[SOLVED] Acer XG270HU - max refresh rate 75Hz instead of 144Hz

[MitjaHD]

On the box it said that the monitor supports 144Hz, but I've been using HDMI for past few months so I got 70Hz max. Yesterday I bought DisplayPort cable in hopes od gettting 144Hz, but instead I got 75Hz max (so only 5Hz more). My graphics card is Nvidia GTX 1060 3GB, resolution is 2560x1440p. Even on smaller resolutions max option is 75Hz. I tried setting refresh rate manually through Nvidia centrol panel but got to max 77Hz and then the display said no signal. I also tried reinstalling drivers.

Looks like my monitor only supports 75Hz because of the part number on the back: UM.HG0EE.A01 despite advertising it being 144Hz.

That is Acer XG270HUA (not Acer XG270HU) - 60Hz screen.

If box says 144Hz, then you have been scammed.
