It might be that your horizontal size knob on your monitor is adjusted too wide and part of the CRT beam is bouncing off the side of the CRT tube and causing a band of light color. On another note: One strange problem I noticed is when the 2320 is de-interlacing, the odd and even fields don't line up on the right hand side of the screen. I.E the HSYNC pulse takes a little longer on the even field for one frame, then it takes longer on the odd field for the next. This creates a vertical rolling effect of pixels on the right hand side. And, when any part of my pointer touches this area the entire pointer starts this rolling effect! It takes about 8 seconds for any particular pixel to travel up the screen. Hmm... 470 lines * 1/60 sec = 7.8 seconds = appox 8 seconds. I wonder whats going on here! ------------------------------------------------------------------------------- Chris Conrad CJC105@psuvm
