So I just plugged in my other computer into the vga port and the display is shaking, kind of like what happens when the refresh is too low. Monitor is the 2405, one system pluged into the dvi...no problems there...the other system with an old Geforce2 Pro 32MB card...with the res set to 1280x1024 and 75 refresh. The vga cable is a 12 footer, but has noise condenser things at each end. This problem didn't happen with the CRT trinitron 20" flat monitor I used before I got the 2405 hooked up...anyone know what I can try to fix this?

I would try setting the refresh rate to 60 Hz. If that does not do the trick, try a shorter VGA cable. A 12' cable may very well attenuate the VGA signal to a level where the 2405 is unable to re-digitize it reliably. Good luck.
 
thanks...I'll try that...in fact it was set to 60 Hz at one time, but didn't help...I'll try the cable...funny how the CRT didn't have any problem...are LCDs really that different in terms of how they process a signal?
