I recently built my new computer, the GPU is an AMD Radeon RX 580, I got the Viotek HA238 as my monitor, using HDMI, it was working great until a couple of days ago when the screen shut off for a few seconds and it came back on stuck in 640x480. I've tried everything, different HDMI cables, which I know arent the cause, they all work on a TV I used to test them, driver updates and rollbacks, i'm out of ideas. I believe this has something to do with the software but i'm not sure. If someone could please help me that would be much appreciated. Thank You!!!
