This is a EDGE lit LED screen. And my research based on other forums leads me to think that this screen is only lit up by a strip at the bottom.

So I do not understand how the backlight-led can be perfect at the bottom and up about 18% of the screen, and then go dim. I can see all the pixels perfectly, it only very dim compared to the 18% at the bottom.

Not seeing how changing the lightstrip might solve this, since they are strong and bright at the bottom.

I have done factory reset of the screen and this is happening on the system-graphics of the screen as well so it should not have anything to do with any signal or HDMI-cable.

On images you can see this. The camera made it burn at the bottom, but on the macbook-screen you can see how even the light is.
