3D PC Gaming with 3DTV as monitor

post #1 of 4
Thread Starter 
Hey guys, I hope this is the right section. This topic didn't really seem to fit anywhere -

I'm currently building a PC, and will be using my 3DTV as a monitor (42" Passive 3D, 120Hz, 1080p).

I've done some research and it doesn't look as simple as I thought it would be to get this setup up and running (figured it'd be plug and play, like a console is.)

What exactly do I need to do to make this work. Do I need to make sure my graphics card is nvidia so I can use nvidia's 3D vision? I was looking at getting an AMD card, but I don't know if it's going to support 3D gaming. It does have HD3D, but I read some things that said it doesn't work well for gaming.

Can anybody clear this up for me? My main questions are:

1) What do I need for my graphics card.. Can I use the AMD I was considering, or do I need to use nvidia for nvidia's 3D vision?

2) Do I need something like Tridef?

3) Can I just use HDMI to connect to the TV, or do I need to use displayport

4) Is there anything else I'm not considering

5) Do you have a similar setup (PC gaming on a 3DTV)?

Thank you for your help. I have the power to change anything at this moment, and I want to be clear on what I need before I go and start ordering parts. Please remember that I am referring to a passive 3D system, so the burden on the gpu should not be anywhere near as intense as it would be on an active shutter based display.

Hmmm... nobody has experience with this?

If you want 3D, whether it be a 120hz 3D ready monitor a 3D HDTV, you would be foolish to go for an AMD card. AMD's 3D system is vastly inferior to that of nvidia's, and nvidia's 3D vision is better supported by more games. AMD's system is barely functional, I believe there are very few, if any, AMD 3D gaming setups. However, its important to know the limitations of each video connection (HDMI/ dual link DVI), particularity since you want to use a 3D HDTV which is limited to HDMI inputs. HDMI v1.4 only supports 1080p res at 30hz(60hz total) when in 3D mode, while at 720p it can do a full 60hz(120hz total). Only with a dual-link DVI input can a display run full 1080p at 60hz (120hz total) in 3D mode. So even with an nvidia card, your quite limited in regards to gaming, you're essential locked to 30hz(60hz total) at 1080p. However you do mention you have a passive display, and I'm not sure how that may change this, but simply put HDMI does not have the bandwidth for 1080p resolution at 120hz(60hz 3D), if your TV can recreate a 60hz "3D" image (120hz total), from a 2D 60hz input, then I'd have to guess you won't be limited by frame-rate issues, but a "fake" 3D image, for lake of a better word.

Nvidia full supports 3D HDTVs, with 3DTV Play you can use the glasses that come with the TV, I'm not sure which TVs are and aren't support though, you should check it out.

Thanks for the post but I just wanted to clarify that in a passive 3d display/tv if is 120hz then it is 120hz in 3d. Passive uses the polarization of light and each lens i the glasses filter a different kind of polarized light leaving your eyes with two different images. This is unlike an active shutter display that display two different images and blocks one eye at a time very quickly reducing your refresh rate to 60hz.
