3D Vision format questions!
Hi all,

I'm looking for a bit of help before I take the plunge and upgrade to 3d projector set up. I have some experience with an old planar style half silvered mirror set up. I am looking to upgrade to a projector set up for 3 main reasons though, gaming on an 80" screen, watching blu ray films in 3d and watching the new Sky 3D channel launching in the UK later in the year. My questions are as follows

- What format do the 3d Vision drivers output to a 3d monitor/projector (side by side, interleaved, frame sequential etc)?
- On my Planar style set up, I output at 1280x1024 to each screen, if 3d vision outputs as side by side, does that mean the actual output on a single cable will be 2560x1024?
- From what I've read, you need a dual link dvi-d cable to run at 120hz, what happens if the monitor/projector doesn't have this input? Will VGA or HDMI work instead?
- Is there a 'maximum' cable length from pc to projector? I know the shorter the better but the realistic minimum distance I need would be about 6m?
- Has anyone found a 'best' 3d projector as from what i've read they all have their individual flaws?
- Sky 3D will be broadcasting in side by side format, I've noticed on stereoscopic player that it has the option to process live video and convert to 3d vision format, has anyone tried this yet and does it run the glasses in sync?
- Can 3d Vision Video player play 3d blu ray movies?
- Is there a maximum number of glasses that the 3D Vision emitter can run?

Sorry for all the questions, just getting really confused as this technology seems to have went so far in such a small space of time from the old DIY set up days with polarized glasses!

Thanks!

Hi

Nvidia 3D vision does not output a specific format that all displays must comply with. Each supported display is registered by Nvidia in a database and modifies the output according to the type of display and display input capabilities. This is performed automatically by the driver and the user has absolutely no control over it. You cannot force a certain type of output, so if your display isn't in the official supported display list it will not work.

Nvidia 3D vision does not support Planar style set-ups any more. They used to be supported by outputting full resolution using two separate DVI or VGA outputs. (one for each eye)
Side by side outputs can be full resolution or half resolution, both are possible although most applications use half resolution (pack 2 frames within the resolution of one single frame) so that the display does not need new input chips.

The requirements for Dual link DVI cables depend on the screen resolution. Low resolutions like 720p or lower can fit through single link DVI but if you want higher resolutions like 1680x1050 or higher, the bandwidth in Single link DVI is not enough, you need a Dual link connection.

Maximum cable length depends on the cable quality and resolution used. High quality cables allow for longer distances, you should be able to find good quality cables that can carry the picture over 6 meters.

Thanks for the quick response!

Can I just clarify then that the 3D Vision drivers aren't limited to Frame Sequential mode? Also, the native res of the PJ i'm looking at is 1280x720 (Acer H5360), would I be able to connect a 6-10m DVI-VGA cable and still achieve 120hz at this res?

Thanks!
