Benq XL2546 240hz problem!

Try another input, not another displayport. Theoretically, if the ports on the card were back, changing cables won't help.
I highly doubt the ports/card is bad, but better to check that initially.

Monitor defects come in a variety of shapes and sizes, and the symptoms displayed here certainly look like other monitor defects I have seen.
