I have a new PC HP Omen 870-258nc (PN 1JV36EA) and monitor HP Envy 27 s (Y6K73AA). Usualy when I start to play some game monitor starts blinking and sometimes go black - power light on monitor is still on, but OSD is not reachable. This happens only if I use display port cable, when I use HDMI cable I have no problem. When the monitor is black or blinking and I press the shortcut Win+E and Win+arrow up (run explorer in fullscreen) or I connect to PC with VNC, the monitor is normal again.
By now I tried this:
-buy shorter (1 meter) display port cable with gilded connectors
-uninstall Windows nVidia drivers and install newest drivers from nVidia.com site
-change resolutions from 4K (3840 x 2160) to 2560 x 1440
-change monitor frequency 60 / 59 / 50 Hz
-use other display port on graphic card (graphic card on this computer has 3 outputs)
-update BIOS on motherboard
-change monitor setting by OSD menu - Input Control and Power Control
Can you please help me to use display port cable? I like to use 4K - 3860 x 2160 with 60 Hz.
Thank you for any advice.
