Hello,

 

I bought an Acer XB271HU a week ago and connected it to a MSI Vortex (GTX 1080 with 2 MiniDP and 2 HDMI). I had to buy a different cable (DP to MiniDP) and the first one was very cheap and flickered on everything above 60 Hz. I did some research and at the end I found a VESA cable listed on DisplayPort.Org (Accell). Everything works great 99% of the time with the new cable (cheap cable often cause the monitor not waking up from sleep, because I read PIN 20 on the cable must be passive and not connected in order to be compliant), but sometimes when I switch on my PC the max refresh rate is 85 Hz. If I unplug and re-plug the cable everything goes back to normal. This doesn't happen every time, maybe 1 time in 3 days, so it's a bit random.

 

I'd be happy to be able to have 144 Hz every time I switch on my PC by default.

 

Any idea?

 

Thanks a lot.
