3DTV play owners - please help
Hi mates,

I just got my Samsung 55" 3D TV and hooked it up with my PC. Everything went well.
I read these forums about how you can use the checkerboard option by renaming "HDMI/DVI" to "DVI PC" in your TV and then connecting the HDMI cable to that HDMI/DVI connector. Well it works and I can finally see checkerboard option available in 3D mode. But I observed following issues on which I definitely need help from people already using such setup.

1) Basically checkerboard is useful when we want to play at 1080p@60Hz. However whenever I launch any game in my PC at 1920*1080@60 resolution, I still get the same error message saying that such resolution is not supported, so the 3D is not enabled. This happens when I try to use Nvidia's 3D by using Ctrl+T hot key.
However if I turn off Nvidia's 3D and use TV's own 3D, I can definitely get the game in 3D Checkerboard format. But I don't feel satisfied with this since
a) The 3D effect is just not good as compared to Nvidia's 3D.
b) Nvidia's 3D gives me more options like more depth and convergence to play with.

Please tell me can I use Nvidia's 3D at 1080p@60 in checkerboard format? If yes, what I need to do for that?

2) If I connect to TV through HDMI/DVI connector, games' performance in 3D gets hurt severely. It just becomes similar to as when I use 3D gaming on my PC monitor where graphics card uses 2 images to display 3D.
However if I connect to TV through HDMI connector, game's performance in 3D clearly becomes faster. It is similar to playing on PC monitor without 3D where graphics card just displays a single image.

Example: Connected through HDMI only, if I play metro 2033 with "Very High" settings DX11 at 1920*1080@24Hz, the experience is much smooth and completely playable most of the times.
However connected through HDMI/DVI, even if I play metro 2033 with "Very High" settings DX11 at 1280*720@60Hz, game stutters become frequent. Is it normal?

3) If I connect to TV through HDMI/DVI connector, colors and picture quality of the TV image become really poor as compared to when I connect through HDMI only connector. Is there any way to fix this?

4) If I connect to TV through HDMI/DVI connector and play some DVD in any media player, TV doesn't enable the options to zoom the picture.
However connected through HDMI only, TV allows me to choose options for "Zoom" and "Wide Zoom".
Please note that I use these options for cutting down the black parts at the top and bottom of the screen so that I can see the movie on all my TV screen excluding those black lines. Anyway to fix this?

5) If I connect through HDMI only connector, then if I enable 3D in powerDVD while watching a DVD, the TV does not enable 3D even if I can see 2 images on TV screen at the same time. Of course, I use the 3D compatible resolutions on my PC while watching movies.
Please note that this behavior is only with PowerDVD software. Using other software like ArcSoft 3D Total Media Theatre, TV successfully switches to 3D.
I want to use PowerDVD for 3D playback, so is there any way to fix this behavior?

Based on various of my previous points, I wonder how do you guys manage to use Checkerboard 3D at 1080p@60 while connected through HDMI/DVI connector?

Please help!
Thanks in advance.

At least with Samsung 3D ready HDTVs it is possible to use either 1080p@60Hz checkerboard or flicker free 1080p@30Hz page flipping (30 unique frames per eye). Both modes are superior to what 3DTV Play has to offer. But you need the 3D vision emitter as dongle to get access to these modes in the nVidia 3D setup wizard. (It is actually not used to sync the glasses as this is done by the TV, so the Samsung or Xpand 103 glasses have to be used, not the 3D vision glasses.)

Unfortunatelly the current 3DTV Play beta driver does not allow the selection of the "Generic DLP" option required for checkerboard or the "Generic CRT" option required for page flipping if it detects a HDMI 1.4 device connected to the graphic card.
So you stuck with either 720p@60Hz or 1080p@24Hz.

To solve the problem you have to trick the driver to think that a monitor or HDMI 1.3 TV is connected.

Hi there,
Thanks a lot mate.
After using the hack, do I still need to use HDMI/DVI connector on back of my TV or can I just connect through HDMI only connector?
I don't want to use HDMI/DVI connector because using that severely deteriorates game performance and also the picture quality becomes much worse than that using HDMI only. Did you also experience this?

This is the price for stereoscopic gaming. The extra rendering of the second view costs extra performance, so you have to expect a frame rate loss of about 30-50% compared to mono gaming.
The TV internal 3D is just a gimmick real time conversion which looks most of the time totally wrong and is at best a good way to quickly get a headache. This has nothing to do with real 3D.

Hm, I don't have any image quality degeneration using this port. And as far as I know this port must be used to get access to the extra 3D modes. You should check the settings of your TV or maybe reset to defaults and make a new start.
Btw. I can actually play in any resolution through that port in checkerboard 3D (4:3 or 16:9 or 16:10 modes). The TV does not stretch up the picture to the full display area but draws it in 1:1 pixel format, using a black frame around the picture.

You may also take a look at the iZ3D stereo driver, as it supports the checkerboard format to. You can install both drivers parallel and activate the one you want to use for a particular game. iZ3D also supports windowed mode and has an internal upscale function, wich can adjust the resolution of some older games with limited screen size selection to the full HDTV screen resolution without loosing the ability to use checkerboard format.

Thanks again mate for information.
You missed the other half of this point; I said if I use Nvidia's 3D using HDMI only connector, there is almost no performance cut at all so I can play Metro 2033 in DX11 at very high settings at 1280*720@60Hz or 1920*1080@24Hz SMOOTHLY most of the times. However if I use HDMI/DVI port, I clearly see the said performance cut and so I experience frequent stutters while playing Metro 2033 even at 1280*720@60Hz in DX11 mode at very high settings.

I don't understand why, but sure I have tested this behavior at least 3 times.

The only idea I have is that this has something to do with the sound. The nVidia graphic card can also transfer sound via the HDMI interface to the TV set. Maybe your sound output setting changes when connecting yout PC via the HDMI port and the sound driver is causing the stuttering.

I had an equal problem with COD Black Ops, after changing audio output to the PC on-board sound interface all stuttering has gone and Black Ops runs smooth as silk.
