I have been wanting to upgrade my graphics card for a long time, as my current one is a geforce gr 740 sc and can't run many current games. I've tried 3 different cards in the past 2 weeks and they all get a check display port prompt on my monitor. I've bought and returned a GeForce 1030 sc, and an amd rx 560. My current one that isn't working is an msi GeForce gt 1030. My monitor is a Hannspree HF199H. I have no idea what the problem is, if someone could help, I would be extremely grateful! This has been one of he most frustrating experiences of my entire life.
