Connecting laptop to lcd monitor via hdid
Hello,recently I bought Samsung 32" LCD monitor and a Sony laptop. Conected them via HDID cable, set resolution on 1280x768 and it was working fine until yesterday. I'm not sure if it has anything to do with yesterdays VAIO updates but sudenly resolution has changed to 1366x768 and view does not fill the samsung monitor above that it's flashing all the time. When I to change resolution lo lower it asks me to check the cable as there is no signal. Does anyone know what can case it?
