First of all, sorry for my bad English. I have a problem of windows 8.1 and my laptop (HP EliteBook 8560w). My display is full HD (1920x1080), 15.6", GPU: nVidia Quadro 2000M. When I installed windows 8.1 (all version, 64 bit) the GPU driver is updated automatically at lastest version (327.31). But some 3rd application ex: Google chrome... is blurry. Then, I choosed the option "Let me choose one scaling option for all my displays" at 125%. All thing is OK. But whenever i started my windows, my display always flashing one time, abour 1-2s. it's very incovenience. Because of that problem, i downgrade to windows 8.0. But i still want to use windows 8.1. Help me, please!!
