Ready for prime time? I have a new build with an EVGA GTX 980 TI video card and an ASUS PB287Q 4K monitor connected with a display port 1.2 cable. Been having some issues with the taskbar not working right, monitor taking a long time to come to life after sleep mode and other niggling issues. Googling and reading leads me to believe that there are problems with the display port technology and problems have been caused by cables also. This afternoon I switched my setup to an HDMI connection and now the monitor springs to life quickly after sleep, the taskbar is working as it should and a couple other problems have gone away. Problem is the HDMI connection will only work at 30 Hz vs 60 Hz for the display port. The difference is quite noticeable when playing the Solitaire game and moving cards to different places. At 60 Hz the move is smooth and quick. At 30 Hz it is jerky and a bit slow. No idea how to fix things but I think I'll try a new cable since they don't cost much.
