RE: Custom Resolution Utility (CRU)

The audio is embedded in the video signal during the blanking periods, so DVI monitors might not sync correctly with that data present.Thanks, thats the explanation that I was looking for. It seems that the DELL 2007FPs can't sync correctly with audio embedded in the vidseo signal. Too bad.

They should if they can handle UHD/4K resolutions because 3840x2160 @ 30 Hz uses more bandwidth.It's worth a shot. Both the receiver and the splitter can handle UHD just fine. I'll try that.

Up to 3 displays are fine and the driver is perfectly bringing the clocks down to 135MHz GPU and 405MHz MEM while sitting idle on the windows desktop. As soon as the 4th display is added, the idle clocks jump to 925MHz GPU (lowest 3D clock) and 4050MHz MEM (3505 MHz when not overclocked). Using the 'Multi Display Power Saver' restores idle clocks back to 405MHz on GPU and MEM (and sometimes even 135MHz on the core) without any noticeable side effects. The only problem is that you have to maintain the triggers that bring the card up to either video clocks or 3D clocks based on usage or running processes. Not ideal, but usable. |
