it does ! what does it have to do with the usb hub, nothing is connected to the monitor usb, neither is the monitor's usb even connected to the pc.
Does your monitor have a USB hub?
What do you mean by similar problem?
Does your system also freeze?
Or only the PG278QR can't detect a signal?
Both HDMI and DP? Tried selecting the input manually?
During I playing some games (Company of Heroes2,World Of Tanks etc) the monitor(PG278QR) stops and message appear ''display port No signal''(both input HDMI or DP) and only restart needed to come back
I 'm trying reinstall drivers of vga card(ASUS MATRIX-P-980) ,previous drivers of Nvidia,change the card to another pci-e slot(ASUS RVE10),change resolution from 2K to 1920x1080 60hz and fresh windows 10 install nothing at all.Of course trying another cables DP or HDMI,unpluged the usb hub of monitor,try to select from menu of monitor input manually the HDMI to DP no good result.
I try my old ASUS monitor VS248H and everything its OK.
I bought this monitor before 2 months for better performance and the problems remains from the first date of use.
I 'm wondering if there is any problem of compatibility about monitor and card but I dont have another card with display port to try this..
