Displays Weird black border around screen

I picked up an old Dell 1905FP at a second-hand store today, but after plugging it in I noticed a black border all around the screen.





In the right lower corner it's just barely noticeable...


... But in the left upper corner quite the opposite


Now since it's not supposed to be my main monitor I don't really mind the border itself, but given its age I was wondering if this might be the first sign of the monitor giving up the ghost completely.

The store has a very nice return policy and I was wondering if I should better return it if it's going to fail quickly anyway. If the black border is just a defect and not "the beginning of the end" I'll probably keep it.

 

If it was mine I would consider returning it. Maybe do a factory reset just to rule out bad settings?

 

Is there a chance you have something like "overscan" turned on in either the monitor settings or in your video card settings? From the weird CRT-esque curves of what is happening I don't think that's the problem, but it's worth making sure first.

If it's old then imminent death will most likely come from the CFL backlight burning out. If you don't mind the weird artifacts at the border and you got it cheap enough, then I'd just keep it and use it.

 

Your LCD monitor is getting very old. There is no fix to it. Old LCD panels does this. I believe it is the polarize layer that is getting unstuck.

 

Thanks for the replies.
I did a factory reset but it didn't help.

Having read the warranty paper a little better it seems I can get a complete refund if it fails within a year, so I'll probably just keep it and see what happens. I really like the adjustable, heavy stand and the great viewing angles (PVA panel, google says), and the border doesn't bother me that much.
