Dell Dimension E521
Service tag:<Admin removal of service Tag>
Monitor: Dell 20-inch LCD model IN2020M
The button battery on the motherboard was failing, so I replaced it.
Upon rebooting, the quality of the monitor image had degraded. It's still usable, but small fonts are not nearly as sharp as they were.
I reset BIOS to factory defaults, but that didn't fix the problem.
I have no idea how this could have happened. Suggestions are eagerly requested.
I edited your post to remove you service tag. Posting that is TOU violation and is for security reasons.
Have you tried reinstalling your video drivers
