asus desktop and lg monitor
I have a mind boggler, I bought a brand new asus desktop last week, and an lg hdtv monitor, i got it home turned it on installed ms office and ran the necessary disks, to start it off it worked fine, i had it near to the phoneline to use internet initially. then moved it the same day to where i wanted it as there is no internet there just yet, tried to turn it on again 3 days later, and there is no communication between the desktop and the monitor, the monitor works fine on the tv side of things, but will not work with the desktop, I have tried 2 monitors and different leads none of which provide any success, Is there any reason anyone can think of that would cause this? am i missing something simple? or is it just going to be a loose connection and neccesitate me taking the desktop back to get a new one?
any help would be greatly appreciated.
