Went through past posts, but did not find a clear answer to my problem. I have now 2 monitors, an CRT (named CTX) and a new one LCD Samsung. I installed Matrox P650, which is double DVI. The picture on LCD is superior, but the picture on CRT is worse, not so sharp. Tried change settings, resolutions, nothing helps much. I use DVI cable for LCD, and RGB cable for CRT (with interface). I wonder what I do wrong, or just the Matrox 650 will not work well with the second monitor which is CRT? Thank you for any help to fix my problem.
