Problem with my Benq XL270Z

[IAmAGoodPerson]

Hello guys, I regularly lurk the forum and was able to overclock my monitor to 175hz.

Because of college I stopped playing CSGO and stopped overclocking it, today after browsing the internet this happened suddenly:

Half of my screen is brighter, I checked the settings, tried to update the drivers and even punched it a couple times but nothing happened.

What it could be? Anyone had this problem?

Definitely a display defect. Sometimes from vibrations caused by transportation, other times it just appears.

if you are able to do a warranty claim, do so.
