A 27-inch wireless smart screen, FHD IPS display, 100Hz refresh rate, 5ms response time, HDR 10, smart power saving, flicker-free, reading mode, Wi-Fi, Bluetooth, 27U511SA-W The screen was bought two months ago and I don't need it, but it has a very faint green line that is barely visible. I uploaded a white picture so you can see the line. It doesn't affect it at all and is barely noticeable, and the screen is new.
