Startup Issue: 4 split screens with tearing

Hello All,

I just got a new gaming pc (Ryzen 3600 / Radeon 5500 XT 8 GB), and it should run HotS really smoothly. On the new PC though, when I load, it looks like it’s trying to load HotS on 4 separate split screens on my monitor, and each has significant tearing or appears fuzzy (can’t really see what’s going on…). I tried the command -displaymode 0, and it starts fine in windowed mode, but once I move it to full screen the same thing happens.

I really don’t want to play this in windowed mode. Anyone know what’s going on? I tried running Borderlands 3 and it runs great…

Thank you for your suggestions and advice in advance.
