Hello,
I have the Acer Predator Z271, bought in April 2017. I am now using this monitor with a gaming laptop, using a hdmi 2.1 cable. The problem is that it is running at 60hz, even with this brand new good hdmi cable that should in theory support at least 120 hz for 1080p. I have gone to the display settings and looked at countless tutorials but to no avail- the maximum refresh rate shown in display settings is always 60hz. Therefore creating this post is a last resort- is there any way to resolve this issue?
Btw, the pc im running does not support display port as far as I can tell, but I figured that the monitor should be able to support a hdmi 2.1 cable since I've heard its used to run PS5s etc at 144hz.
