Any idea what could be the cause? As it is on all 4 edges.Yes looks like an extreme case of backlight bleeding, it should be covered by warranty.
Yes it does. I can even see some indication (this corresponds directly with the lit regions in the pics) for it even when the monitor is powered off.Does it look the same when you are booting from BIOS?
Ran the tests. Results for all of them seem satisfactory to me. But are you recommending looking for something specific in those tests?Run these tests.
