Hi cliff24245, and welcome to TSG.
There's no guarantee I'll have a solution, but it might help someone here to help you if you told us the brands and model numbers of both the monitor and the new video controller card (the actual card manufacturer info, not the information about the GPU on the card).
Did you install the latest drivers for your new card?
