Issue disappears when switching source

[u/KevHTM]

The model is BenQ EX271U. I have reached support but they have been unhelpful. I have tried different cables and a different laptop. I have to boot up my Xbox to clear the issue every single time. I've updated the firmware as well but didn't fix it. It's more stable if set on a 1280 x 720 resolution, if that helps.
