The human eye is very good at spotting things like this. Alas, I wish it were that simple. I have a few pixels on my 760C that work great on certain colors (blue comes to mind) and on a black background, but fail on red or remain blue. One pixel is partially stuck, and it will flicker under blue only, but is fine everywhere else. A program, as described above, would be great for picking out pixels that do not fail in a on/off-->white/black situation. ------------------------------------------------------------- | Mark Bell |"A sufficient quantity of delusions | |800 College Drive #126 |constitutes a valid reality, while a| | Vineland, NJ 08360 |lack of an appreciable amount of | | 609-327-5994 |reality constitutes a delusion" | | bytehead@mindspring.com| | -------------------------------------------------------------
