Hi,

i have 3 optx running surround. all was well until one of the monitor turns black all the sudden !

its turn on, looks like the back light is on and the ON light is lit. thing is, cant access the OSD, no matter what i try. Nvidia control panel and Device Manager says that no problem with the monitor. but why there no display. did the self test, change Dvi ports on the cards, nothing works. check my dvi port on gc with the other two monitor, no problem. change the cable with the other two monitor = no problem. only with this one monitor ??

upluging all dvi cable from all three monitor, the two which is ok pop out the normal "no signal" prompt, but not with this one monitor. can anybody assist before me going thru dell ?

thank a bunch in advance.
