I just bought an LG W2253 model monitor, i have attached the DVI cable andthe monitor will only display a desktop image. (a pic i took in the mountains). i cant get it to respond in any way. analog side works fine. the only change i cant find was i used the install disk this morning and *BAM* no mor digital. it worked fine prior to the disk but i cant seem to see what has changed ??? can anyone please help??
