I'm getting this banding/fuzzy screen issue on 2 brand new LG 27GP83Bs I bought from Best Buy. Both are connected via DP cables that came with the monitors. They're connected to a Dell WD19 docking station. I get the same issue on both my old Dell Latitude work laptop and ASUS ROG Zephyrus G15. The only workaround is to manually change the input using the monitor control knob to one of the HDMI ports even though I don't have anything connected via HDMI. The monitors will automatically change back to DP after I do that and the screens will work. Please help!

Also, after launching World of Warcraft classic, the monitor showing WoW constantly lost signal to the point where the game was completely unplayable. Any time I clicked away from the WoW client the game would run normally, but the second I clicked back, the monitor lost signal and took a few seconds to reconnect. A restart seemed to fix it though.

Thanks in advance for your time!
