UP2716D, pink stain appearing, need help diagnosing

Hello everyone,

I have a Dell UltraSharp UP2716D that suddenly started showing a pink stain at the bottom of the screen. I ran a color test, and it seems the stain only appears on white, green, and grey backgrounds.

Does anyone know what might be causing this issue? I tried using a new HDMI cable, but that didn’t help. I also reset the monitor to factory settings, but that didn’t resolve the problem either. Any recommendations on what else I could try?

Cheers
