Be Careful With the 3D-capable LCD Monitors Supporting HDMI 1.4a

February 11th, 2011 · 26 Comments · Other S3D Tech


Acer is the first company that already has a 3D-capable LCD monitor with support for stereo 3D over HDMI 1.4a and this is the model Acer HS244HQ (it uses only HDMI) and will have two more models that will have stereo 3D support over both Dual-Link DVI and HDMI 1.4a – the Acer GN245HQ and Acer HN274H. This for a lot of people automatically means that they would be able to replace the need of a 3D HDTV with one of these 3D LCD monitors, but this is not entirely true. You should be for example able to connect any 3D-capable device that outputs stereo 3D content using the frame packaging method defined in the HDMI 1.4(a) specification such as a PlayStation 3 console. But you will not be able to use an Xbox 360 console in 3D mode with games that do have native stereoscopic 3D support with the reason for that being the fact that the Xbox 360 can output stereo 3D in various formats, but not in the frame packaged format. Usually the Xbox 360 uses Side by Side output and that is something that you can manually switch from a 3D HDTV, but not from the any of the mentioned above monitors as the do no have built-in support for any of these additional modes. So again, a word of warning when you are planning what to buy – a 3D HDTV or a 3D-capable monitor with support for HDMI 1.4a, based on what you are going to use it for…

    Is it possible to do 3d with ati/amd card atv120hz via the DL DVI as well as via HDMI 1.4 on these monitors?

  • 2 gadget78 // Feb 11, 2011 at 23:54

    would it be possible for one of the party’s involved (Microsoft, or Acer) to update there device to then support each other ?
    Althou i i presume acer wouldnt ever release any kind of update for a monitor (done over USB etc?), so it prob more likly that we would be waiting on Microsoft in this instance …
    does the Acer HN274H have componant in ? (as ny thinking is that the side by side format was more supported by componant input)

  • 3 Bloody // Feb 12, 2011 at 00:06

    Yunti, for AMD/ATI GPUs only through the HDMI 1.4a interface.

    Monitor firmware updates are not something that a normal user can usually do by himself as they require special hardware to do thew flashing, so that is not an option you can expect. Maybe other vendors that will come out with HDMI 1.4a-capable 3D monitors can add additional modes support…

    The Acer HN274H does not have component input, only HDMI, DVI and DSUB.

    jeez thats retarded, something shouldnt be hdmi certified unless it can do all the formats

  • 5 fnunezj // Feb 12, 2011 at 00:34

    It is possible that Microsoft could update the Xbox 360 in the coming months??Or until the next Xbox???….

  • 6 SikSlayer // Feb 12, 2011 at 01:36

    Chris K:

    It does all formats. It’s just that the 360, and things like cable boxes that were made before the 3D standards came about will only be able to use the side by side techniques, and this display doesn’t know what to do with them. The side by side methods would even work on component, and don’t require HDMI.

    It is sad to see this display not support that though, its just not a matter of certification.

  • 7 Chris K // Feb 12, 2011 at 02:19

    ahh thanks for the info :)

  • 8 park // Feb 12, 2011 at 02:50

    thx 4 ur info

  • 9 craig davis // Feb 12, 2011 at 06:01

    There is no 3d content on the xbox 360 anyway

  • 10 gadget78 // Feb 12, 2011 at 22:06

    yes is a shame that they didnt also include this in with the monitor, as we cannot now say its THE best display to have as there are still some restrictions
    craig, there are a number of games that do support 3D, just not wide spead or advertised very well :(
    Hope MS can fix this with a update ? or is it a hardware limitation ?

  • 11 craig davis // Feb 13, 2011 at 00:30

    what 360 games support 3D?

  • 12 gadget78 // Feb 13, 2011 at 03:15

    its very few well 3 i think !!! But not sure if its a hardware limitation for it to not out 3D Via HDMI
    But for a list of games go here :)

    vga over BNC is much better

  • 14 Gerald // Feb 13, 2011 at 19:30

    Damn – I really was considering to get one of those, glad I know now I won´t get my Xbox running with it (I want to play Crysis 2 in 3D, maybe Black OPs too). I doubt there will be a patch that will get the HDMI output up to speed.
    I really hope there will be a better option available soon. :-(

    Is The Acer HS244HQ compatible with 3DTV Play Nvida??

  • 16 PeZzy // Feb 14, 2011 at 08:47

    The XBox360 is very old hardware so who bothers to use low-framerate 3D on it. I do have a PS3 so it would be nice to plug it into one of these Acer monitors and watch a 3D movie.

    It would be interesting to know how the Acer HN274H performs with a PS3 as there have been so many poor implementations of HDMI1.3 on monitors in the past.

    AMD may have HDMI 1.4a but it does not have 3D driver like nVidia 3D Vision so to play games using ATI graphics card one must use third party hackware like tridef to get the DirectX hacked and be able to output 3D game content trough HDMI 1.4a

    Are you sure Xbox 360 won’t work? From what I understand the Xbox 360 Slim Console 250GB only supports 3D output via HDMI 1.4a and is the only console built with that kind of HDMI. I was really hoping to buy the Acer 27 for it to work with X360. What kind of 3D display do you recommend that actually support X360, PC and PS3 alltogether? I’m thinking 27-32 inch in size.

  • 19 Bloody // Feb 17, 2011 at 13:29

    The Xbox 360 has one general issue regarding stereo 3D support and that is the fact that the console does not come with native support. This means that in order to have stereo 3D support you need a game that has a built-in native S3D support in its engine. So the compatibility with 3D displays is generally down up to what the specific 3D output types are supported. So there is no guarantee what may and may not work with specific display, especially if the display does not have support for multiple S3D formats and the user being able to switch between them. That is precisely why a 3D HDTV is the best choice to ensure compatibility with the Xbox 360 when talking about 3D support. And most if not all 3D LCD monitors with HDMI 1.4 are not going to work, because they need specific frame packaged 3D content through the HDMi 1.4a, and the usual output from Xbox 360 in 3D format is in Side by Side format which apparently is not supported by the 3D LCD monitors.

    Bloody, can I complain to Acer writting an email where I say that they sold me a HDMI 1.4a product without all the formats that HDMI 1.4a supports?Because I am reading in the official HDMI website that HDMI 1.4a supports “Side by Side”..I didnt read in any catalogue of Acer that the Acer HS244HQ doesnt support “Side by Side”..

  • 21 Bloody // Feb 19, 2011 at 13:12

    Fernando, you can output Side by Side even without having HDMI 1.4(a) and that is probably causing the issue when the monitor needs to detect it is getting 3D content and automatically activate the 3D mode as it does not have an user switchable menu for different modes.

  • 22 Fernando // Feb 19, 2011 at 21:10

    But this monitor doesnt support “Side by Side” automatically/manually…and I didnt read in any Acer catalogue that the Acer HS244HQ doesnt support it.They MUST WARM this.

    And the Side by Side isnt only for Xbox.In Spain (where I live) Digital+ is using “Side by Side” in his 3D channel. In PC I am using TriDef and when I try to watch a 3D Side by Side video, the monitor doesnt reproduce it..

  • 23 SG // Mar 24, 2011 at 18:35

    The HDMI 1.4a standard clearly states that all formats (frame packaging, side-by-side horizontal and top-and-bottom) are mandatory. The “problem” with the acer hs244hq seems that it does not support 1.4a but “only” 1.4 (which means that the fancy stuff is optional and only frame packing is mandatory). Alas, on Acer’s homepage the HS244HQ is advertized as 3d-ready and not as supporting HDMI 1.4a. I have also read this from users (that actually bought this monitor).

    If true the GN245HQ will indeed have this standard and should then by definition also work with the corresponding formats (see also http://www.engadget.com/2011/02/09/acer-debuts-gn245hq-monitor-with-hdmi-3d-support-from-nvidia/).

    So, IMHO, the heading of this article should be revised.

  • 24 Bloody // Mar 24, 2011 at 18:49

    The article covers not only Acer HS244HQ, but also the newer Acer GN245HQ and Acer HN274H models. These monitors do not recognize 3D content not in frame packaged format and do not have an option to switch between different inputs in their menu (I’ve personally verified that!). So although some specific Top and Bottom and Side by Side inputs have been added as mandatory formats for 3D TV broadcasts in 1.4a it seems these monitors do not have support for them. And we are just about to start seeing affordable 3D DLP projectors with HDMI 1.4a support and I suspect that we may have the same issue present there as well…

    I have tried Sky 3D with it and does not work. The picture is displayed side by side. So this is to back up Bloody’s comment.

  • 26 poplar // Apr 15, 2011 at 10:03

    I bought HS244HQ as I expexted it working with 3DTV PLAY on my GTX465 PC. The result is, Nvidia cannot recognise is as a 3DTV, stereoscopic pane disapeared in Nvidia control.
