So I recently bought a 20" Trinitron endoscopy monitor to use for old school games. It has the best color I've seen on any monitor. I was blown away by the realistic contrast on all the sources I put through it.
A problem arose when I got to a scene with a large white beach, I noticed that I have three very small scratches very close to each other on the screen, making an area less than a square half-centimeter (which is very noticeable when you're sitting close to the small monitor). They're pretty distracting, because they look black against most uniform backgrounds.
I couldn't feel the scratch with my fingernail, so I know it is possible to buff it out with some sort of fine grain abrasive. However, I feel they wouldn't be very noticeable if I could simply polish the spot with something that would fill the scratches and allow some light to pass through.
