May I ask what kind of video card you are using at the moment? are you running windows 10?
It is possible that either the drivers for the card, update for windows or new firmware for the cac-1051 is needed. preferebly update all above
for me to determine where the problem could occure i really need above information, you could also send the question with the information requested to [email protected]
additional you could run a dxdiag on your system and send the outcome to [email protected]
