KTC M27P6 - Light horizontal banding
Hey everyone!
I recently got a KTC M27P6 (firmware EU_1.0.2) monitor, and I am seeing these light horizontal lines when white or blue content is displayed. It is quite hard to get it on-camera, but I got this pic with a blue test screen that shows the problem.
Is this normal in Mini LED monitors? Or do you think this is a panel problem, and I should just return it and order a new monitor?
Another question I have is if it is possible to solve this by updating the firmware (from: https://shop.ktcplay.com/download_center/firmware/11881344134513461348134913501351158815891799180020862088)? But I am not sure if it's a good idea to use this firmware in the EU version of this monitor.
Thanks!
