    The difference is more about the uncompressed 7.1 audio, different languages, extra features, etc. that won't be on the iTunes download vs the blu ray content.

    Picture wise, unless it's fast moving, and dark scenes, it's pretty good from iTunes.

    Stichz asked me elsewhere:

    Hey Connector. As you seem to be a very helpful guy, and as you kindly replied to my questions in the Plasma Sky review thread; I'd thought I'd ask you regarding HDMI usage with the iPad.

    I have never really thought of using my iPad 4 as a console-like machine on the TV, but after stumbling upon your HDMI thread it hit me how awesome that would be. I don't know why really I havn't seen that as a possibility, but that matters little now when I've learned that it is possible . Anyways, to the question.

    In your very honest opinion, how is the HDMI gaming working with input lags; do you notice any compared with playing directly on the iPad? Let's take Plasma Sky with iCade for instance, as that game got a very responsive sensitivity, how does that work on your TV through the iPad with input lags?

    Also, if it isn't a bother, how is it working generally with streaming 1080 videos? If I would buy this which I absolutely plan to do (if it is working as I hope), I would definitely watch a lot of Netflix movies but also youtube videos. Would that work flawlessly as you wish?

    I'd like to thank you in advance and I hope that I don't put any annoying or bothering question for you. I couldn't think of anyone better to ask than you.

    Have a great day.
    Best regards

    Hiyas Stichz,

    With my hdmi connector, I see no lags whatsoever, there seems to be a very slight delay maybe from screenshots, but by naked eye, I can not see any delay at all. You might want to read most of the hdmi thread cause there is a lot of info on here that talks about different delays and stuff like apple tv too.

    However, for the new lightning connector, there does seem to be a little more delay concern, read

    http://forums.toucharcade.com/showthread.php?t=173262&page=23

    Plasma sky works great with my icade core joystick and hdmi tv. Though since it is a portrait game, it does not use the whole screen. But plays great, and I notice no delay.

    Streaming movies will be no delay on hdmi tv. Even appletv buffers it well, so appletv should be able to stream with little to no delays.

    I use an app called tubebox to download my youtube, then watch on hdmi tv. Streaming it too will work with no delays.

    Do yeah, in a nutshell, buy hdmi tv! If anyone else wants to answer go ahead, or if you have any further questions, please ask.

    Some speed comparisons

    1, the Lightning adapter has its own About dialog under Settings > General > About, at the bottom of the main (middle) group. It's visible even after removing the adapter, unlike with the old RGB / composite cables (Settings > General > TV Out in the second (iPhone / iPt; below VPN / iTunes Wi-Fi Sync) / last (iPad; below Reset) group). Here's mine:

    [​IMG]

    As you can see, my adapter's firmware is 6.1.0 and the hardware is 1.0.0. (No such dialogs with the old, “passive” 30-pin HDMI / VGA adapters, of course.)

    2,
    I've shot some additional videos to check out whether it's indeed the iPad 3 that delivers far worse HDMI mirroring performance in fast-paced games than any other model. It does – every single other model based on A5 or A6 produces waaaaay faster mirroring speeds.

    My benchmark videos are as follows. First, some explanation.

    a, All direct grabs (non-camera videos) have been shot with the Elgato Game Capture HD in its “Preserve Source Format” mode, which, with all recordings, recorded 1080p30 footage, despite the original output being, in cases (for example, with iPhones in mirrored mode), of far lower resolution.

    b, All dual-monitor camera shots have been shot with a Nikon P300 using its 720p60 mode. This, during playback, is played back with 30p; that is, with half the speed. It's an excellent tool to measure lag – the main reason of shooting dual-monitor shots, in the first place.

    (Note that I haven't shot a demo video in every possible configuration.)

    In all these cases, I was using the 30-pin HDMI adapter (A1388; that is, the first model – see http://www.ilounge.com/index.php/backstage/comments/apples-digital-av-adapter-gets-interesting-little-changes/ ) with the “old” (30-pin) A5+ iDevices (iPad 3, iPhone 4S) and the new Lightning – HDMI adapter (firmware version, as has already been stated, 6.1.0; HW: 1.0.0) on the iPhone 5 and the iPad 4. In some dual shot cases, I used the, otherwise, lag- and resolution-wise, identical VGA adapter.

    Note that the lag of the Lightning-HDMI (and VGA) adapters have been widely discussed at both MacRumors ( http://forums.macrumors.com/showthread.php?t=1550766&page=18 ; see the posts starting with #428) and TouchArcade (http://forums.toucharcade.com/showthread.php?t=173262&page=23 ; dedicated posts starts at #221). It's in the 80-100 ms range, as opposed to the, in most cases, lag-less old 30-pin HDMI / VGA adapters. It's still much better than the at least 50% higher lag of the wireless AirPlay (I don't even mention the maximal 30 fps framerate, which is half of that of any cabled solution), which makes action / racing games almost impossible to play.

    For the tests, I used three games:
    - After Burner Climax by SEGA: a very fast-paced game without native TV out (that is, you need to rely on simple mirroring), which very easily shows the vastly reduced framerate of the iPad 3 on the external screen.
    - Real Racing 2: both the iPhone and the HD version support native (non-mirrored) TV out resulting in far better performance on the iPad 3 and far better resolution on small-screen devices.
    - Real Racing 3 (Universal): no native TV out support either, which means having to mirror, rendering the iPad 3 pretty useless and iPhones / iPod touches displaying pixelizated images.

    After Burner Climax (mirrored), 1080p30 direct grabs:

    iPad 3:
    http://youtu.be/qmVQufnjs8g
    As you can see, it's waaaay worse (plenty of dropped frames) than anything else A5-based.

    iPad 4:
    http://youtu.be/yppWpsVZjRo

    While (as with the iPad 3) still having excellent resolution, it delivers waaaaaay better framerate. While the iPad 3 version was pretty useless, the iPad 4 is the opposite.

    iPhone 4S:
    http://youtu.be/KNLrjVPGsRA

    iPad 2:
    http://youtu.be/6YC-OKQ7aWU

    Unlike the iPad 3, it's much better. Of course, its resolution isn't as good – but still far superior to that of the iPhone 4S.

    Thanks a lot for the replies and help Menneiyys and Connector, definitely helped me a lot.
    I've read many threads now regarding that lag with the Lightning connector, and I've watched videos of it, and I must say that it is unfortunately not what I expected. As a hardcore gamer, the lag that have been described, and what is easily seen in many videos that I've watched, is far far away from acceptable to me. I mean I remember the input lags of some ms with Playstation controllers on the PC, and then we're talking minor delays but still enough to not be acceptable. Luckily these days it's working as intended, but seeing the lag expressed here is like going back in time. I'm suprised it was this bad really.

    I guess I'll have to conisder the streaming movies part instead, as that feature will indeed work as intended. I'll see if I go for it, but for now I'll have it on hold.

    Sorry to bother you, and again thanks for the friendly help.

    Do you have an iPad 2 or an iPhone 4S lying around? If you do, use them for playing: they use the lag-free, old 30-pin adapters and are the fastest for gaming WRT the pre-A6 devices - pretty much suitable for most of today's titles, in both mirrored and native mode.

    The iPad 3 is, when mirrored, pretty much useless with many fast games (see my demo videos in mirrored mode). Native - non-mirrored - HDMI output is far better on it, though - if you don't use mirroring, it can be a decent gaming machine too.
     
  6. All Pangea games are free today, read below concerning airplay widescreen support.

    Also, Toucharcade's airplay widescreen list has been updated

    http://forums.toucharcade.com/showthread.php?t=173262&page=6

    Wow, 4 of these games have airplay widescreen support!

    Bugdom 2, cromag rally, enigmo 2, and nucleus all have airplay support, so if you have hdmi or appletv, give it a try. Take a look at this screenshot and notice the controls don't show on the tv version, and there is no stretching needed to play the game in fullscreen.

    I've been testing the natively TV output-enabled games to find out more on their compatibility etc.

    So far, I've tested most titles on Connector's list ( http://forums.toucharcade.com/showpost.php?p=2638368&postcount=52 ) on the iPhone 5 (6.1.2, with the Lightning-HDMI adapter), the iPhone 3GS (5.1.1, with the RGB cable) and the iPad 2 (6.1.2, with both the RGB cable and the 30-pin HDMI adapter). I've found out the following:

    - Asphalt 6 and 7 are absolutely cr@p when it comes to TV out. Over HDMI, it used low resolution, even on the really fast iPhone 5. You won't want to play either of them on a hi-res external screen if you have an iPhone or Asphalt 7 on the iPad 2. (There, Asphalt 6 is rendered at 720p with substantially better quality.) An example framegrab from the directly grabbed video:

    [​IMG]

    (direct link to full-size image: https://dl.dropboxusercontent.com/u/81986513/042013/hdmi/asph7-grab.jpeg )

    This is the dual (camera) shot:

    [​IMG]

    (direct link to full-size image: https://dl.dropboxusercontent.com/u/81986513/042013/hdmi/asph7-dual.jpeg )

    - the RGB cable on the iPhone 3GS is supported by quite a lot of games. The most important exceptions are all Gameloft titles (which, otherwise, run just fine on the phone) and FIFA ones. These same titles work just fine over the low-res RGB on newer 30-pin iDevices; for example, the iPad 2.

    - some Pangea games are buggy on the natively 16:9 iPhone 5. For example, both Bugdom 2 and Cro-Mag Rally exhibit major bugs when run on the latest iPhone over the HDMI adapter:
    a, the field-of-view (FoV) is somewhat narrower than that on the screen – as opposed to the case on 4:3 iPads. (See previous images posted in the thread)
    b, pretty low framerates
    c, there's only picture in the lower left corner of the screen.

    Let me show you two framegrabs of this:

    [​IMG]
    (dual mode; original image: https://dl.dropboxusercontent.com/u/81986513/042013/hdmi/bugdom2-dual.jpeg )

    [​IMG]

    (direct grab of the same frame; original image: https://dl.dropboxusercontent.com/u/81986513/042013/hdmi/bugdom2-grab.jpeg )

    - several titles with, otherwise, native TV output support switch back to plain mirroring on the iPhone 5.

    The current version of my comparison chart is at https://dl.dropboxusercontent.com/u/81986513/042013/hdmi/tvout-games-1304272351.ods (LibreOffice format) / https://dl.dropboxusercontent.com/u/81986513/042013/hdmi/tvout-games-1304272351.xls (Excel)

    I've shot demo videos of ALL the tested apps; for the time being, on the iPhone 5 only. I've created two types of videos:

    1, a 720p half-speed one (shot at 720p60) so that you can see both the Lightning adapter lag (see my previous, dedicated posts on this) and the true framerate of both the original screen (if there's mirroring) and the external TV screen. You can easily spot dropped frames if you advance over the YouTube video frame-by-frame. (You may need to download the video files first.) You'll also directly see whether a title is just mirrored; if it's mirrored, whether the on-screen controls are mirrored too etc.

    2, a 1080p30 direct video grab using the Elgato Game Capture HD, directly recording the output content. You can use this for quality (e.g., effective resolution) testing. I really recommend, among other things, the video at http://youtu.be/Z8k07uNV_eA and http://youtu.be/NmAg_15btK0 so that you can see the rendering quality and speed of Asphalt 6 and 7, respectively. (The titles start right at the beginning in both videos. Dual camera shots are at http://youtu.be/LyzXesztE8E and http://youtu.be/x1mWHCxXkm0, respectively, should you want to see how I started the games etc.)

    I've denoted the camera shots as “dual” and the direct Elgato grabs as “grab”. Note that some other duals (Real Racing 2, Race Illegal- High Speed 3D, Nucleus, Pilot's path, Cro-Mag Rally, Touch Tanks 5, Bugdom 2, DH4, Pinball HD, Chopper 2, Enigmo 2, Beat Hazard Ultra) and grabs (in additio to the ones listed with duals, Max Adventure, NOVA3, MC4, Metalstorm, Sky Gamblers – Air Supremacy, Sky Gamblers - Rise Of Glory, Zombie gunship, Sonic and SEGA All-Stars Racing) are still being uploaded to YouTube. I'll update the list when they're there:

    Grab: http://youtu.be/b7txO8W1_f0

    EDIT (Sunday 14:20 GMT):

    I've added two benchmark videos showing the HDMI pass-through and the RGB -> HDMI conversion lag of the Elgato Game Capture HD capturer unit. I used this model to simultaneously capture the full-res video of the iPhone 5's screen along with passing its HDMI signal through to the external monitor so that I can shoot the "dual" videos at the same time.

    As you can clearly see in the video I posted to http://youtu.be/HV7kSZtWl5U , there isn't any HDMI pass-through lag. Note that I used the iPad 2 as the source as it has the old, 30-pin HDMI adapter, which doesn't lag either - unlike the new, Lightning-HDMI (and VGA) ones. As you can see, the 60 fps benchmark video playback (which I shot at 120 fps, as usual) doesn't show any lag on the external screen in mirroring mode.

    Note that I've also shown on the video the lag between tapping the pause / play icon and the actual video stop / start. (This is why I quickly tap the icon, making sure I lift my finger quickly so that you can exactly count the frames between the system's registering the tap and the playback to restart / stop.) It's about 4-5 frames, that is, around 60 ms. This was necessary to find out whether the RGB->HDMI converter of the Elgato Game Capture HD has any lag. Using the standard "let's stop playback and see whether there's a different number on the external screen than on the internal and if there is, let's count the difference given that the video played back is a 60fps one and the recording was shot at 120fps" as it's not possible to mirror the internal screen over the RGB (or the composite) cable. As it turns out, there isn't any added lag when using the converter in the Elgato Game Capture HD, which is indeed great news.

    The RGB converter lag demo video is at http://youtu.be/PvK1_zdIP-Y

    EDIT (Sunday 14:59 GMT):

    My two iPhone 3GS + RGB half-speed videos (which means there isn't sound) are also online:

    http://youtu.be/nHK-wPDzuyM

    http://youtu.be/Piv_MPGRzdw

    I'll also upload the direct grabs some time - after publishing the iPad 2 videos.

    BTW, on my iPad2, I've run into exactly the same problem as on the iPhone 5 over HDMI. At least here the FoV is somewhat wider on the external screen, unlike when mirroring from the 16:9, where the opposite is true. This can also be seen in the next framegrab. (Will later upload the iPad 2 videos.)

    (Over RGB, there's only 4:3 mirroring. At least it's not buggy.)

    Just uploaded a new, enhanced version of the chart to https://dl.dropboxusercontent.com/u/81986513/042013/hdmi/tvout-games-1304282339.xls (Excel) / https://dl.dropboxusercontent.com/u/81986513/042013/hdmi/tvout-games-1304282339.ods (Libre).

    1, I've added the following games:

    War Pinball
    Quarters!!
    Touchgrind BMX

    2, I've extended and cleaned up the device- and connection-specific columns; most importantly, the iPad 2 HDMI and RGB ones.

    Feel free to comment on it!

    I plan to publish the entire article & final list sometime next week, preferably after having finished uploading all the iPad 2 dual & grab videos to YouTube.

    I am a little puzzled by your comments about ipad 3 hdmi mirroring. I kinda have to strongly disagree since I game with an ipad 3, ios 6.1.3.

    One thing is, you seem to use a vga adapter with your ipad 3 for your youtube vids. That vga adapter probably uses some real old technology, so that is what is influencing your results. Second, do you have the latest ios 6.1.3 on your ipad 3? The latest updates are very important for fast hdmi framerate play on the ipad 3.

    None of your youtube views of the ipad 3 are what my ipad 3 with hdmi tv look like. I know it is hard to view the youtube clips cause youtube itself doesn't have high framerates and the clip is small, but your ipad 4 youtubes are very close to what I see with my ipad 3 with hdmi.

    For example, afterburner climax for the most part is silky smooth like your ipad 4 vid, there are some times on the ipad 3 where if there is a ton of enemies on the screen, it lags a little, but this is an inherent cpu thing, not a hdmi mirroring issue.

    In fact, from all the articles I have read, it would seem that ipad 3 mirroring would be better than ipad 4 mirroring, due to the lessor resolution of ipad 4 hdmi and also the seemingly more delay.

    Most every mirrored hdmi tv game looks way better on the tv screen than on my ipad 3 screen, and almost no game on the market really has poor framerate issues. Afterburner climax maybe the best example of a game with really fast framerates, but for the most part, it looks fine on my ipad 3 on hdmi tv. Clearly nothing close to your youtube vids, I will take a look at some of your other stuff, but there is something wrong with your ipad 3 vid comparisons, I think it is either the vga adapter or not being on the current ios or something else.

    1. Could you post a demo video of your iPad 3 running the game in mirrored mode? I'm dead sure the framerate will decrease to even 2-3 fps when there's action - unlike on the screen of the iPad 3 itself. Not so with any other (current, that is, A5+-based) iDevice I've tested (iPad2, 4, iPhone 4S, 5) - they have much faster and almost flawless mirroring.

    2. I've tested it on two of my iPad 3 6.1.2's. One JB'n and the other isn't - that is, it surely wasn't a JB problem. The same cr@ppy framerate on both on the external screen, while the internal one was just fine (close or maybe even equal to 60 fps) even when there were tons of action.

    3. I've re-run the tests with the 30-pin HDMI adapter (the older model, not the iOS 5.1+ only one) - basically, all my new tests are done with it because I can directly capture its signal with the Elgato capture box. Exactly the same results.

    4. I have Afterburner Climax version 1.0, officially purchased (not pirated); size: 225,512,239 bytes.

    BTW, very important: my "dual" videos are all played at half the speed as I've shot them at 60 fps so that the framerate can easily be assessed on a 30 fps-only platform like YouTube too.

    Today, while shooting the War Pinball demos, I did find out the Lightning lag was VERY annoying - much more so than in racing games. (After all, in pinball, timing is VERY important - much less tolerating lag than in a racing game.)

    When played over a lagless connection (RGB or the old HDMI adapter), the game wasn't at all frustrating.
     
  15. Yeah, what is the easiest way for me to capture it? I don't have a nice vid cam, only an iphone 4. I can try to get something up on my skydrive, but my setup isn't jailbroken, is there any easy way for me to get the vid? Or is using my iphone 4 using video mode, the only way? How did you get your vid captures to look so nice?

    But yeah, your ipad 4 vids are pretty much what I see on my ipad 3 hdmi. I'm sure the ipad 4 version is better than the ipad 3 versions framerate wise on many of the higher end games, but I am still trying to determine if this is a cpu issue or an hdmi issue. It is important to note that I have never seen ipad 4 mirrored hdmi in actually operation, since no one I know has it.

    But something is amiss, I can't quite figure out what it is yet. I think that vga adapter that you use in most of your ipad 3 vids is old and not representative of hdmi on the ipad 3. But there seems to be another issue here too. Maybe it is ipad 4 vs ipad 3 cpu/gpu power, maybe it is lightning vs 30 pin hdmi, maybe it is ios or jailbroken issues, or something else. I am not sure yet.

    Let me try to get something posted vid wise, but let me know what is the best way to do so.

    Also, I am going to link some of your posts to the hdmi toc (table of contents on the first page this week). I will let you know soon about it.

    Sample of what I am doing on...

    Also, I will add an entry for you to have a dedicated page linked to the first page, I am still working on it, so give me a couple of days. :D

    Could his tv be the issue?

    Both of you seem to have stock iOS iPads and connectors running the same games, so I guess it could be due to the differences in your tvs, and perhaps in how your tvs decode those HDMI signals.

    Also, tv settings like game mode (i.e. no post processing) and noise reduction could also affect it...

    No post processing here - this is why I have zero lag with non-lIghtning cable / adaptor types (RGB / composite / old 30-pin HDMI and VGA).

    Today, I'll make more experiments with my iPad 3's - will shoot the same suite of games I've created videos on other iDevice types with.

    The iPhone 4's video capturing capabilities are more than sufficient - it records excellent video footage, even if it's 720p30 "only". Just put it on something while recording as I've done in, say, this setup (here, shooting a resolution chart, but the same can be done with shooting a screen):

    Thanks!

    BTW, I see you're linking to the Panic article, Lightning-wise. It has pretty much misleading info. While I did have encountered "blocking" in some cases (particularly in Max Adventure), it was in no way as bad as those on the Panic pictures. Text is output with absolutely no MPEG compression artefacts, unlike what the Panic folks have stated.

    In the meantime, I've switched to HDMI because I can directly capture it (see all my "grab" videos). The video at https://www.youtube.com/watch?v=qmVQufnjs8g already uses this setup.

    Note: this is a 1080p30 video played back at nominal speed, unlike my "dual" shots filmed at 720p60 and played back at half the speed. Nevertheless, it still shows the issues I've encountered; for example, check out the major framerate drops at 0:08.

    Will re-shoot the dual setup (in 720p60 mode) today, via HDMI.

    BTW, which HDMI connector type do you have? Mine is the older (A1388), not the newer (A1422) - see http://www.ilounge.com/index.php/backstage/comments/apples-digital-av-adapter-gets-interesting-little-changes/ on the differences.

    Nevertheless, as these 30-pin adapters are all passive, I'm pretty sure they aren't the culprit here.

    When I first saw some of your ipad 3 vga vids, I thought them quite slow compared to hdmi. But after you posted one what you say was hdmi ipad 3 vid, with clearly poor performance, I was really puzzled.

    But now that you mention that you are using the older adapter (which was primarily made for the ipad 2), it is starting to make more sense now. Yes, I am on the newer adapter. I am almost positive the performance of it in all ways is far superior to the old one.

    I was under the impression that the older hdmi adapter only outputted 720p (which might have to cause more delay to upscale the picture by the tv to 1080p) and also did not mirror games well from reports that I have read. That is why I have always posted here for people to buy the newest and greatest from Apple not a generic from China.

    Take a look at this photo, this is from Syntheticvoid's generic China hdmi adapter.

    Granted this is an ipad 2, but compare this to mine with a newer adapter... This almost looks like a snes game. While I am not sure if that generic is close to the older Apple ipad 2 connector, you can tell there is a significant performance and graphic degradation.

    I think there is alot of processing done in the hdmi adapter themselves, so they are like mini computers. I didn't think so at first, but the more I read and seeing the innards of some, the newer versions they are, the better in terms of processing speed.

    Now, that leads me to the question, is the new lightning hdmi connector faster than the newest 30 pin hdmi in terms of processing speed?

    But that maybe one big flaw in your comparisons, not having the latest hdmi connector for the 30 pin, I think. Also, ios 6.1.3 did increase framerates which helps with hdmi. 6.0.1 did too. Certain ios upgrades seem to do a lot performance wise to framerates both to ipad 3 and hdmi tv.

    In most games, it actually seems like framerates are doubled on tv. What I mean is, if I play NFS Most wanted on my ipad, I feel like I am going about 50 mph. But on hdmi tv, I feel like I am going around 100 mph.

    There is NO visibile lag, delay, or framerate drop from ipad 3 to tv. There is no way that I can see any difference. Yes, there is maybe a milisecond delay time or something as evident in my screenshots, but there is no way that a naked eye can see this. I surely can't and my eyes are almost perfect.

    Take a look at this Iron Man screenshot, you can see if you look at the trees or stripes on the street, the small amount of delay. But there is no way to see this with my eyes, and the tv sense of speed seems much faster than on my ipad 3 screen.

    However, there are two considerations for improved hdmi experience in an ipad 4. One is the 2x better cpu/gpu. I am sure for a game like Afterburner climax, since it is probably the #1 cpu burner game on ios right now, it runs better framerate wise on a ipad 4. So naturally this game will look better on ipad 4 hdmi cause the framerates will be better on the ipad 4 itself. On the ipad 3 though, after ios 6.1.3, the framerates got WAY better, and I think are between 30-60 fps most of the time. Same on tv.

    Second, the lightning hdmi connector may have a faster processor than the newest 30 pin hdmi connector. This is actually something that I would be curious about. I will try to get a fairly good video to state my case, and then maybe if we both agree that it is far better looking than your video of hdmi ipad 3 performance, then it would be cool to try upgrading to 6.1.3 and possibly maybe purchasing a newer 30 pin hdmi connector (you should be able to return it within 30 days, and then again, I would only recommend getting one from an applestore cause anywhere else you may just get an older model).

    But in reality, it maybe better to use a better test of an average framerate intensive game, cause afterburner climax is the worst game on the ipad 3 framerate wise, though it isn't too bad after 6.1.3. Only slight lags.

    Maybe something like Real Racing 3 (with outside car view, not cockpit view) would be a fairer game to do a comparison between ipad 3 and ipad 4 hdmi.

    Kinda makes me wish someone I knew had an ipad 4 with the lightning hdmi. It's kinda sad that apple doesn't really promote it much, and I can't see it on display at an apple store. :)
