I purchased two screens to plug in a dual DVI and one in Hdmi. Immediately adjust the brightness, once made a glaring difference between Hdmi dvi and especially in black. HDMI makes lighter colors, while the DVI makes the colors more natural, impossible to adjust screen live I had to do with the Nvidia Control Panel. At the end of an hour's work I almost succeeded (to quibble) to make the colors less bright and equivalent to dvi (especially for black phew). So good screen for those who put the PC in superb colors and Hdmi dvi for the game console (I tested on a xbox one superb qualities no problem) but the dual and have the same color will have to go to coal. For making me work one star less ^^
