[citation][nom]clonazepam[/nom]It won't do 120hz. If it did, it'd be listed in the specs on Viewsonic's website and it would be 3D Vision certified. It has no such certification. It uses AMD's 3D method, which does not utilize 120hz. I realize what he was saying about ultra-fast response. It's 2ms grey to grey. That performance isn't uncommon at all in the market.Edit: I did actually go to Viewsonic's website and read the specs listing directly from it before I posted, fyi. Once you read that it's pretty clear... well actually no its still murky, but better. Just remember, if it supports 3D Vision, it'll be plastered everywhere. If it supports blu-ray 3D and AMD, it'll be like I'd said in the previous comment. You can use nvidia gpus but you wont be using nvidia's 3dvision glasses/hardware. It'll be supported through nvidia's software, 3D TV Play and I think it's 30 or 40 dollars. You might be able to get it to work with the software packaged with the monitor, but its probably not supported or reliable.Edit 2 (lol): If anyone's still curious how I magically came across this information, it can referenced on pages 10,13, and 16 of the user manual.[/citation]
AMD HD3D does use 120hz for it's 3D. The part that is unusual is how it uses HDMI 1.4a to pass compressed images in order to get enough info to display two images per 60hz (or 120hz). Not all 120hz monitors are 3D vision certified.
I know this because when I run HD3D on my monitor, the monitor itself shows it running at 120hz. The same as when I run 3D vision. I'll take a closer look at that specific monitor.
EDIT: I'm also not saying you are wrong about this specific monitor, just you also made some overly broad statements. You may be right about the 120hz, since it's not listed as 120hz. I'm not as familiar with the polarized method of 3D.
After looking around, this sight does confirm it won't run at 120hz:
