Question Does anyone know what this is?

[Lag724]

I have a VIEWSONIC VG1921wm 1600x900 display LCD moniter. I just started using it after it being in storage for 1 year. It worked fine the last time i used it. the moniter works fine but shows a grayish-black overlay of some sort. I uploaded this image, to show you what i mean i used a black background.

Does anyone know what this is?

The screen is damaged. Where was this stored?

 

[Lag724]

It was stored very poorly in a cardboard box and the screen was placed horizontally(screen facing downwards).
Do you think it can be repaired?

rather than repairing you can purchase a new one as it will have warranty... or else if you want to repair then you need a LCD replacement. cost-wise it will be similar

okay thought so, do you know which one would you prefer for coding and gaming LED, LCD, IPS or any other type

For your needs, IPS will more than suffice in colour accuracy and motion. There is OLED but may be too pricey. Look at LG UltraGear IPS models in your price range. 400$ or there abouts will get you a pretty decent display.
