Transparent vertical line on screen

I have an HP Omen 15-ce0xx laptop - it is only a few months old. Yesterday when I opened the lid and turned it on, there is a 3 inch wide transparent vertical line, off-center (right) of screen. It is transparent enough to still work with, its just slightly darker where the line is (like the brightness is turned down). When the background (or opened window) is white, it just shows as a transparent line (like a grey transparent block) but when the background is black (like my desktop) you can see a ‘burned’ image of the last thing I was working on (photoshop), but only where the vertical line is - I never noticed before if anything else prior was burned onto the screen. It has only been about 20 minutes since I closed that program, so I don’t know if it is permanently burned on there. As I type this, the grey line covers half of this window so it doesn’t prevent me seeing what I need to type
