Okay, does anyone at all have a 55" (or larger) Nvidia Vision 3D display? - AVS Forum

I've been searching and searching, I can't seem to get updated information on what 3D TVs will work with Nvidia 3D vision.

I'm ready to buy a 3D TV for my HTPC; and, want to make sure it is optimal for 3D bluray; and some light 3D gaming.

I went to Nvidia website; but have a very limited selection of tiny LCD monitors; which obviously isn't intended for home theater/3D bluray.

I think Arcsoft TMT5 supports Micro-polarized 3D LCD displays; but, might be limited to only 60hz; whereas, Nvidia 3D Vision Ready displays can directly work at 120hz for 3D.

Hopefully someone has already been through this and knows all the details.

Thanks,
MKANET

Requirements for a GeForce card:

- BR 3D: Any HDMI 1.4a 3D display + 3D glasses bundled + TMT/PowerDVD
- Stereoscopic 3D gaming: Any HDMI 1.4a 3D display + 3D glasses bundled + NVIDIA 3DTV Play (software, $40). The resolution is limited to 1280x720@50/59.94/60Hz per eye (= 1280x1440@50/59.94/60Hz in total [in Frame Packing format]; that's HDMI 1.4a 3D specs).

NVIDIA 3DTV Play (software) converts standard PC games into 3D. You don't need NVIDIA 3D Vision Kit = IR transmitter + 3D glasses + 3DTV Play, nor does it work with a HDMI 1.4a 3D display.

BTW most 3D Vision-ready monitor work at 1920x1080@60Hz per eye (= 1920x1080@120Hz in total [in Alternate Frame-sequencing format]) over dual-link DVI, that's beyond HDMI 1.4a 3D specs. The current HDMI does not have enough bandwidth for 1920x1080@120Hz (nor 1920x2160@60Hz).

Maybe I understanding this wrong, but Nvidia TV play doesnt look like it's what I want; which is good to know; since I dont want to have limited display resolution of 720. I'm currently looking at various Mitsubishi DLP TV's. Several of them are Nvidia 3D Vision certified.

Do these Nvidia Vision TV's require two separate DVI cables plugged into the TV at the same time? I remember reading something about "dual-DVI"

These older DLP displays support only checkerboard 3D format so that half of the resolution will be lost for BR 3D (if that matters for you). I am not sure about gaming. Perhaps the same is true for gaming, 1920x1080@60Hz per eye is actually halved, unless there is a "dual cable" solution as you mentioned (I highly doubt it). But PQ of checkerboard is surely different from downresolutioned 1280x720 because

Left eye image (1920 x 1080) -> *downsampled* in an offset grid pattern ((1920 x 1080)/2) -> *upsampled* to the full resolution (1920 x 1080)
Right eye image (1920 x 1080) -> *downsampled* in an offset grid pattern ((1920 x 1080)/2) -> *upsampled* to the full resolution (1920 x 1080)

Downsampling is necessary to transmit both left and right images combined into a 1920 x 1080 frame at the rate of up to 60Hz over HDMI 1.3. A relevant thread.

Renethx, what Nvidia driver settings would I need for 60Hz per eye with duallink DVI cable? Would it be NVIDIA 3DTV Play (software) or real Nvidia 3D using Nvidia 3D glasses? I am guessing I would HAVE to use a display that supports native 120hz to split it to 60hz per eye.

EDIT: I found the below information from one of your older posts. I want what you mentioned below. Which large TV's support this? Maybe Mistubishi 120Hz DLP displays?

A "120Hz Frame-sequential 3D Display" is a display that takes 120Hz frame sequential video *input* over dual-link DVI or VGA or HDMI (only 720p or lower). This is exactly NVIDIA 3D Vision (-ready display) and this works only with NVIDIA graphics and NVIDIA 3D Vision Kit.

MPEG-4 MVC
-> frame packing 1920x2160 @23.976Hz (decoded by GPU or CPU/PowerDVD)
-> frame sequential 1920x1080 @120Hz for certain PC monitors or 1280x720@120Hz for certain non-full HD DLP projectors (converted from frame packing, with 2:3 pulldown)
-> over

dual-link DVI or VGA for 1080p@120 or HDMI or VGA for 720p@120 (output by a 3D Vision ready NVIDIA graphics card)
-> frame sequential 1920x1080 @120Hz displayed.

Dual-link and single-link DVI cables are just normal DVI cables (see monoprice.com) where dual link uses all the 24 pins, while single link uses only 18 pins out of 24. Single link supports up to 1920x1200@60Hz, beyond which dual link is required.

Most 3D displays support 120Hz native refresh rate (60Hz per eye) with active shutter glasses or DLP glasses (for DLP displays). An exception is interlaced (interleaved) polarized 3D displays.

NVIDIA control panel has Stereoscopic 3D section. You will need NVIDIA 3D Vision Kit if you are going to use a 3D Vision-ready display.

It looks like the latest Samsung 3D ready plasma/LCD display is a good option because it supports HDMI 1.4a 3D for BR 3D and checkerboard for 3D games. Read roller 11's threads:

- NVIDIA forum: HDMI1.4 checkerboard for all! 3D Vision software fix here!.

from what I remember reading:

if you do NOT buy anything special (other than a 3D tv and 3D bluray software) you will be able to watch 3D bluray movies as long as your drivers are up to date.

3DTV Play is basically a paid driver update allowing you to not only watch 3D bluray, but game as well.

please someone correct me if im wrong.

No, Mitsubishi/Samsung 120Hz DLP does not support 1920x1080@120Hz input (they don't have a dual-link DVI connector). Only 3D Vision-ready 23"-27" PC monitors support it.
