It might. It could have less lag over DisplayPort than over DVI, but I doubt that's the case. You'd have to test again with DVI to make sure.bb23 said:Oh yeah, I used a DVI to VGA adaptor to allow the Dell to run off my video card. The HP is on the displayport. The HP had to be set down to 1280x1024. Does any of this matter?
If there's no lag at lower resolutions, then it probably doesn't have any lag at the native resolution either.
One thing I'm really interested in is if it can do higher refresh rates, but I don't even know where to begin explaining how to do that. It would require adding a custom resolution, but I've seen people have trouble getting valid resolutions to work due to EDID restrictions in Windows. Single-link DVI also doesn't have enough bandwidth to do higher refresh rates at 1920x1200, so it'd have to be done with DisplayPort. The main thing I want to know is if it skips frames or not, which should be easy to see just by moving the mouse cursor. Then I wonder how high it can go. The specs claim it can only do 59-61 Hz, but the specs are never a good indicator of what the monitor can really do.
