MyKneeCannyWhackIt Posted January 18 Share Posted January 18 I have a 4k monitor plugged into DP1 of my card. However, when I populate any of the other DP ports or HDMI ports with my 4K TV, the new display doesn't work properly (it'll come up for a second then disappear to no signal/black screen). MacOS recognises that there is a 4K TV plugged in, but the TV its' self shows no display. The same setup works perfectly in Windows. EFI & specs attached below. https://drive.google.com/drive/folders/1-qMuoPuhizR3d-FKcYpkthXq-EFl3bt1?usp=sharing macOS 12.7.1 i7 6700 MSI Z270N Gaming 5 MSI RX580 8GB Armor Edition Broadcom BCM4352Z Quote Link to comment Share on other sites More sharing options...
