Hi, we got dell u2711 monitors, and geforce 580 gtx cards (with displayport). We want to check the cards if they are capable of 10bit display or not (win7, gtx580, display cable, u2711). But we are having problem making a proper test. We tried viewing the usual ramp.psd (from ati) in photoshop cs5 (as some adobe forum topic suggested), with performance options set properly, but the ramp remained striped. It wasn't a surprise, but it was when the same happened with a quadro fx 1800 also (with which should be fine). We checked with moninfo.exe, and it displayed that the geforces are using 10 bit color. In nuke setting the viewer to half-float, and checking "use gpu for viewer" makes ramp smooth on any monitor/card, not just the dell/geforce. So my question: is there a way to test 10bit display mode for sure? Or is there anyone using similar monitor/card combo and can confirm? I read a lot forum topics, but the statements are contradictory, some saying the geforce drivers are not supporting yet, some aren't. Any advice on this?
Thanks, Gabor
