I have an Acer monitor that quit working with the computer. When it is initially powered up the self test runs so I know the lamps working and I assume the circuitry controlling the screen is working since there is text printed etc.

However it will not display anything from the computer. A secondary monitor works ( a little 15" Viewsonic) with the G card and on the Motherboard serial as well.

Does anyone have an idea what the issue is? Is the monitor toast?

Any help would be appreciated.
