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.
