make sure it has enough airflow

25
Display Technologies If you have Dead Pixels on LCD monitors
If persistent get a new one. Manufacturers allow for small numbers of them but you don't have to.
26
Display Technologies Artifacts
Video Ram - replace snap in new ram card t and test it. (no testing video ram - soldered in)
27
Display Technologies Incorrect color patterns
Check cable especially if VGA snap in new ram card t and test it. (no testing video ram - soldered in)
28
Display Technologies DIM image
Not enough light Replace
29
Display Technologies Flickering image
Replace cables - notorious for this especially HDMI cables
30
Display Technologies Distorted Image
Run at native resolution adjust geometry of projector a little bit
31
Display Technologies Burn in
Old school plasma monitors LCD - image persistance - fix it by putting a different screen on it
32
Display Technologies - Symptom Oversized images and Icons
Windows tools will help to adjust
