Mele, I don't understand what is going on here either. What is your video card, is it new, what is the model? Consider replacement of it, or see if you can get a buddy to swap his for a few days. Or better yet, try your 1901 on any other PC, either in analog or DVI mode. It just doesn't make much sense that two monitors now are bad. Trust me, I put my trinitron out to pasture 2 years ago when I went to the 1900FP, and now the 1901FP. So your experience is unique, you are just going to have to believe me and thousands of others. Hang in there.
