Hello everyone on the Tech Support Forum. This is my first ever post. For past few days I am facing problem with the monitor. It's a LG 500G CRT monitor. Few days back it automatically started changing resolution. Initially it was momentary but two days back the picture (Screen!) appeared stretched horizontally & didn't restore to normal. I reinstalled drivers (LG 563N that I have been using). Also tried with the monitor's H size adjustment using monitor control panel. Recently I have installed Microsoft optical mouse which has a USB as well as PS2 connection. The PS2 is mount on USB & connected to PS2 port. Could this be the cause? Presently I have changed resolution setting to 1024*768 which is OK. But if I restore resolution to 800*600, then picture gets stretched. Also during this time sometimes the screen would turn light blue with wavy lines! Pls help as soon as possible.
