Unable to run 144hz. Generic pnp monitor

[greenery]

I'm using a Acer KG271A monitor. When i try to switch it from 60hz to 144hz, it will black screen for awhile and then back to 60hz. Also on device manger it is called Generic PnP monitor rather than the model name.

What cable are you using?

display port

Are you using crimson to set the monitor refresh rate or general display properties?

 

[greenery]

General display settings. (Right clicking on desktop)

 

[atomicWAR]

I assume you are running AMD GPU since a free-sync monitor? Yes?

 

[greenery]

Nope. Running on a gtx 770, is that the reason?

 

[atomicWAR]

It is possible. I have seen some free-sync display issues with nvidia cards at higher refresh rates. Regardless lets see if we can fix this. Go to nivida control panel by right clicking the desktop.

1. right click desktop choose Nvida control panel.
2. Under change resolution choose the 144hz as your refresh rate.
3. Click apply at the bottom of the control panel window.
4. lmk if this works.

Might be... the 770 is an outdated GPU not capable of such high end refresh rates

I tried this just now, after i press apply, it will hang for a moment but nothing happens. I read else where to uninstall generic pnp monitor and followed it. Now there is no option for 144hz, only 60, 59, 50hz.

I believe the gtx 770 is capable of 144hz. though I am not sure if it require dual link DVI...looking into that now though

 

[atomicWAR]

I was wrong a GTX 770 can only handle 120hz with a single cable...see if setting 120hz works the way i mentioned earlier.

 

[greenery]

there is no 120hz to select, only 60, 59 and 50hz.

unfortunately nvidia not playing nice with freesync displays is a known issue but it isn't an across the board problem, just a frequent problem. You may need to If your display is new you should return it for a g-sync version if possible...otherwise you may be stuck with 60hz regardless of the nvidia GPU you use...that or switch to AMD based solution.
