I have tried to fix mouse lag on Q70R (as a PC monitor) but no succes so far. I have read that changing from 30hz port to 60hz port fixes the problem but I can't find any information about Q70R's HDMI ports. I tested every ports but the mouse lag remains the same. Resolution doesn't have any effect (UHD and 2560x1440 tested) either. Nothing wrong with the cable (59,90 euros Hi-Speed cable with Ethernet) and Windows or nVidia settings. Can anybody tell which port is the best to connect a PC?
