Hello. I have a monitor DELL U2415B which recently started to dim over half of the screen. After many, many restarts it gets back to normal, but after source change or power-off, the issue comes back. I tried several things like:
- Resetting monitor settings to factory settings
- Changing power-cord
- Changing the HDMI cable
- Changing the HDMI port
- Changing power outlet
- Changing the source input (several laptops and PCs, even a console)
- Changing the rotation of the monitor

All of these result in the same issue.

This is what it looks like: https://drive.google.com/file/d/1BwBFGSSxII5ZLNwm_-EiYSGleiI0WsaP/view?usp=sharing

My question is - is it repairable? I wanted to sell this monitor either way, but I want to make sure before sell in what condition it is.
