I have a Hp 27x monitor (1080p, 144hz, 1ms). A week ago all was good until one day i turned on my laptop and lo and behold, 900p and 60hz?! I tried reinstalling drivers, putting dp mode 1.1 and 1.2 but to no avail, hdmi worked yesterday but now i can't get it to, rn im using my DP at 900p 60hz, my specs are i7 8750h. 8gb ddr4 ram 2400mhz, 1060 6gb, nvidia driver version 389.27, help a homie out, i can't stand 900p!

 

 

(forgot to merntion i tried custom display, 1080p works but 144 makes my laptop screen flash while my monitor having no signal)

You can set separate refresh rates for different monitors, can't you?

Try newer ones, say 399.24 if not the newest 419.17

When the hp 27x is selected and i pick 144 that happens, newest drivers don't  work
