Question Half screen different contrast

[Norm272]

very strange yesterday I was watching a video on youtube about color grading, and since then my screen is split in two with one half having more contrast, I tried rebooting and even whent in the bios to reset to default and nothing changed, still have that line and it is driving me crazy, my laptop is an Asus X456U with intel graphics and a nvdia 920mx, any ideas ?

Try this...

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.

You may also want to try hitting CTRL + SHIFT + WIN + B to try and reset your graphics driver as another possible fix.
