Part of display is darker

[mgZero]

Right side of my notebook's display is darker than the rest of the screen. I have contacted hp support but so far, their suggestions did not do the job. My lap[top is about 1.5years old. But I have got extended warranty.

Welcome to the HP support community

I understand that your notebook display is darker, I am glad to assist you.

If you haven't, Please try an alternate monitor to understand if this is either a hardware or a software failure, 

if the issue does not appear on the alternate monitor, you may need to replace the display assembly on your computer, 

if the issue appears on the alternate monitor/TV as well, re-install the graphics card drivers & update it from the official HP Website: Click here 

If you don’t have an alternate monitor, I recommend checking if the issue appears on the BIOS screen (restart the computer and tap on F10 to access BIOS) 

If the issue does not appear in BIOS, reinstall the graphics card drivers & update BIOS using the above link, 
If it does, you may need to replace the LCD/Repair the computer: 

Keep me posted.

If this helps, please mark the public post as an accepted solution so that it benefits several others.

Cheers.
