Have you tried a different port or even a different cable, I've had a weird issue like that before with a disport cable, would work on one system but not the other, I hate problems like that, but if you have, probably be best to contact the manufacture.
Yeah Asus do have good products, but their warranty service sucks, If I were you, I'd bring it up and ask for a new card since its under warranty.Hi, yes tried it All, ASUS says its DOA, and Will try a reapair 🤢 its only 5 months old, why dont they give me a new one.
