i have bought this montior like 3 or 4 months ago, when i alt-tab from a game i get a very long black screen (2-3 seconds) delay that i didnt have before on my older monitors,also on display port i sometimes get a blackscreen after i log in the windows and i have to remove and replug the display port or turn off the screen for a second then turn it on again,when i switched to the DVI today i dont get that blackscreen however the max refresh rate i can get is 60hz, so my question is why do i have such a big delay when alt-tabing and is there a way to get more than 60hz on the DVI connection ? my graphics card is gtx 760
