Acer GN246HL Screen flicker

tylerbogue

Bought an Acer GN246HL from Newegg this past November. It's setup as the main monitor, secondary is a Acer S211HLbd. I set up the GN at 144hz with the correct DVI cable, and the S2 at 60hz. I have an EVGA 02G-P4-2676-KR GeForce GTX 670 FTW LE 2GB 256-bit GDDR5 PCI Express 3.0 x16 HDCP Ready SLI Support Video Card.

 

Anyways setting the monitor up was a breeze, always happy with Acer products. This issue is that when my PC wakes up from sleep mode, the Acer GN screen will flicker, mostly a grey static looking line horizontally across the middle of the screen. I tried doing a screen cap and recording but the software doesn't catch it. 

 

Unfortunately the only ways I know how to resolve the issue is to either restart the PC or go and change the refresh rate of the Acer GN to something other than 144hz, but I just choose not to "save changes" and have it revert back to 144hz, both fix the issue but I am baffled to what is causing the problem. Any advice or suggestions would be appreciated. I can post any logs, pictures or specs that you need. 

 

My first thought is to change the cable but didn't want go out and buy another one if I didn't need to.

 

Also drivers are up to date. using GeForce Experiance to get the latest drivers.

Not sure what you could try other than another cable or different type of input. Do you have another monitor you can test with to see if it does the same thing with a different monitor. It could be the signal from the computer and not the monitor or cable.

I'm probably going to get another cable soon to see if that helps. I was using the other ACER as my main for 2+ years with an old LCD as my secondary with zero issues, so I think it has to do with the 144hz setting and I can only get the 144hz with the current cable/input. Thanks the response and idea's I will try them and let you know.
