For the last month or so, I got a metre strip on the screen just like watermark! It shows some percentage from 0% to 100%. Sometimes, in weeks, as the percentage increases, the screen goes black and revives only after 4-5 hours! Re-starting the computer doesn't help either!!!! It remains black!

This time when this happened, I waited for two hours, then I push the + button from the + and - buttons on the front of monitor (I think they are meant for controlling visibility of the screen! ) AND the screen came back to normal!!!

Can someone tell me, what is this watermark and how can I get rid of it?

I tried to take its picture by clicking on "print screen" but it didn't show on the captured image!!!!

I tried to draw the picture, though its not the exact replica of the actual image that appears, but it can help you understand and recognize what it looks like....I'm uploading it:
