ST2420L/ST2421L Monitor problems

So my Pc and 21inch dell monitor turned 1 the other day and now the montior is being a bugger. I started to notice a bit of flickering but didn't think to much of it. I turned it off and let it sit for a few hours. But when I booted her up this morning the screen was dark. Not off, I could still see my desktop and all that but it real dark like my backlight has died or something. I'm kind of upset because even typing this is straining my eyes. I have tried turning the brightness up and all that jazz, nothing seems to work.

I would appreciate it if someone could help me figure out what has happened, Thanks!

First, run the monitor  Self-Test and then the Built-in Diagnostics. What are the results?

Ok, when I did the Built-in Diagnostics the top right corner of my screen was a lot lighter. As you shift your vision towards the bottom left it gets darker. Same with all the colors and the colors are solid across the screen.

Thanks For giving the time to help.
