Question Viotek GN24CB Monitor Flashes/Flickers on 120hz and 144hz Thread starter Thread starter KevinTH Start date Start date Aug 11, 2020 You are using an out of date browser. It may not display this or other websites correctly.You should upgrade or use an alternative browser. Aug 11, 2020 1 0 10 #1 I've had this monitor for over a year now and this has never happened to me. I noticed that now when I set the monitor to 144hz or 120hz the screen starts to flash/flicker. I have made sure all my drivers are up to date and I have also reset my computer and changed multiple HDMI coords.This is what it looks like- View: #2 I have a Viotek GFT27DB that has similar issues, although I'm not entirely sure it's monitor related. I built my new computer in january this year, running with a 3800x, RTX 2080 Super, 16GB 3200MHZ Ram, ASRock X570 board, and that monitor. Ever since I got it, had some weird graphical issues. Flickering and flashing like crazy on Skyrim near water regardless of refresh rate (Although 60 makes it happen far less frequently and take longer to begin, once it starts it won't stop). WoW does it too but barely. Overwatch barely does anything glitchy but a black box/rectangle likes to appear and flicker in the top left of the screen when I first join matches oftentimes.I thought it was the monitor but then I tried my old monitor and discovered it was still happening on that, and then even my old computer began doing the same issues.So I'm wondering if maybe there's some kind of weird driver issue or software issue out there, maybe with ASRock motherboards (My old PC had one too) or with Ryzen's or NVIdia cards or maybe Windows 10, I have no idea.Anyway my point was that my monitor does things too but I have no idea if it's Viotek or if it's a different cause. #3 I have a Viotek GFT27DB that has similar issues, although I'm not entirely sure it's monitor related.
