In their newest video about the Pro Display XDR Linus mansions, that, on Windows, you only can have 4k resolution.
I think he used a thunderbolt add in card and hooked that up to the monitor. Most of them are quiet old or just support DP v1.2, which would make sense, because the max res of 1.2 is 4k60.
However in a Video made by Snassy labs the display worked with a surface laptop 3 at 6k. Which doesn't even has Thunderbolt. So I think thunderbolt isnt needed for the Pro Display XDR and you just need a DP 1.4 USB type-C connector. And isnt the virtual link port on the new RTX lineup just that?
So the Pro Display XDR should work at 6k with the Virtual Link provided by the RTX lineup, or am I wrong?
