AMD HD3D Technology + Panasonic 3D HDTV (TX-P50VT20E) and iZ3D

October 30th, 2010 · 19 Comments · Other S3D Tech

After trying the Panasonic 3D HDTV (TX-P50VT20E) with the latest DDD TriDef software with no success in making the TV work with stereo 3D content from the PC, I’ve decided to switch to iZ3D. And I was not even sure if the iZ3D Driver actually does have support for working with 3D HDTVs using HDMI 1.4(a)’s frame packing through AMD’s video driver.The reason for that is due to the fact that they don’t clearly state that and the naming convention of their stereo 3D outputs in the driver is not helping for that at all. But after some discussion about it here and going through the iZ3D forums I saw people confirming that the driver has the support and should work, so back again to the testing…

Unfortunately after a few hours spent in making sure everything is right – reinstalling video drivers with the latest Catalyst 10.10c, the latest iZ3D Driver 1.12 build 4016, trying with different cables and cable adapters there was still not luck in making things work the way the should. The closest thing was kind of making them act as they should, but not exactly as you can see in the video above. I’ve managed to get the same results as with the TriDef Ignition software – the picture is there, you can see some depth of the objects on screen when wearing the glasses, but there is annoying flicker and artifacts all over the screen making it totally unusable in this state.

As you can see from the video the driver shows “ATI Presenter”, which means that it is using the Quad buffer support which in turn should mean that the sync should be perfect and everything should be working just fine, however it is not. Note in the video that even before activating the stereo 3D mode the on-screen image is having the same strange behavior, just no 3D, and after activating the 3D mode the FPS counter still shows 120 fps in the game which is kind of strange… shouldn’t it be 24 or maybe 48, after all this is in the 1080p/24Hz? After switching to 720p resolution from the game to ensure support for 60/120 fps the strange behavior of what is being displayed on the screen is still not gone – the artifacts and flashing are still there. So still no luck with the AMD HD3D technology in terms of support for my Panasonic 3D HDTV, and the problem is that I’ve only seen a lot of complaints from other people trying to make their 3D HDTVs work too. But since both iZ3D and DDD have the same issue I’m starting to think that they are not at fault here (although they can improve in a few areas too), but the actual problem lies withing AMD’s Catalyst driver that probably needs an urgent update or yet another hotfix to resolve the issue.

Trying AMD HD3D Technology with Panasonic 3D HDTV (TX-P50VT20E)

October 28th, 2010 · 53 Comments · Other S3D Tech

When I got the Panasonic 3D HDTV (TX-P50VT20E) I was eager to try out the recently announced AMD HD3D Technology with the TV as well as the 3DTV Play functionality from Nvidia, although I’ve already seen the later in action. So I started with a quick test with 3DTV Play and as expected everything worked just fine by using a 5 meter DVI to HDMI cable to connect the GTX 480 to the 3D TV, the driver immediately detected the TV and enabled the 3DTV Play functionality. Everything was running just fine and I was able to try out some games in both 720p and 1080p in 3D, as well as Play a Blu-ray 3D movie with PowerDVD 10 Mark II, watch a few clips with the 3D Vision Video Player and play a few 3D photos. Everything worked pretty much fine, apart from having some trouble with a few games to make them work in 3D mode at 1080p resolution with 24Hz. The other thing that kind of surprised me was the red warning message I’ve got when I tried running a game at 1280×720 at 60Hz per eye in stereo 3D mode with 8xAA – the drivers have automatically lowered the AA to 4x to ensure better performance. Now, that would be acceptable if you have a low end video card, but with two 480s in SLI running at 720p 3D mode with 8xAA should be like a breeze… I’d might want to try playing at 64xAA, because at 4xAA with that resolution you are still quite far from smooth edges. But anyway, I’ll dig more into that later on when I have more time to test that, so now let me get back to the AMD HD3D Technology with the 3D TV…

Now, switching to the other AMD-based system with an ATI Radeon HD 5970 video card I was ready to test the Panasonic 3D HDTV with the same cable and with the software that AMD and their partners provide for ensuring the support for their AMD HD3D Technology. Just to make sure I reinstalled the required Catalyst 10.10 drivers, installed the latest DDD TriDef software that has support for HDMI 1.4a transmission of stereoscopic 3D content (the latest iZ3D Driver still does not support that). However when I ran the TriDef 3D Experience launcher (you can see that on the video) or TriDef 3D Ignition with a game the result was kind of disappointing. The depth of the 3D objects can be seen, however there is a weird flicker and a lot of annoying flashing artifacts on the screen that totally ruin the experience. I’m not sure where the problem lies yet, because for example on AMD’s supported hardware page there is no mention of the TX-P50VT20E, but there is support for TC-P50VT20 which is pretty much the same. But the reason for the problem might not be that at all, but in the fact that you need a 6000 series video card in order to use that mode, although AMD and DDD say on their websites that the AMD HD3D Technology is compatible with 5000 and 6000 series of GPUs.

So if you have a 3D HDTV and an ATI/AMD video card from the 5000/6000 series you can try the DDD TriDef software and its HDMI 1.4a mode for 3D and report your success or lack of such in the comments below. The TriDef software is available with a 14 day trial period, so you can download and test it on your system without actually having to buy anything. Also anyone else having the same issue with his setup as shown on the video above?
