[NAME] A DP 1.2 input can support 4K 60 Hz.  The only reason you need HBR3 bandwidth levels is to get a 4K 60 Hz signal to the hub while you're also carrying USB 3.x.  So as long as the hub can receive an HBR3 signal and then pass out through its DP output as HBR2 -- which I think it should be able to do -- then you would be fine.  In terms of cabling, if it's a USB-C hub rather than a Thunderbolt hub, then you would just need a USB-C cable rated for at least USB 3.x Gen 1.  Some USB-C cables are only rated for USB 2.0 and power, and they would not be suitable.  And then for the DP cable, you shouldn't need anything special there.  DP 1.2 has been around for a very long time, so any DP cable you find should support at least that standard.
Hi! Sorry for asking a dumb question. SO, I have an XPS 15 (2021 with 3050ti), and it has TB4. I want to output 4k 60hz in SDR. Can these dongles work? They claim 4k 60hz. [URL] [URL] The second link is esp concerning, as it says 4k 60hz only works with NVIDIA 2070... I saw an answer about an older XPS and wonder if it applies to these above docks and my newer XPS: [URL] "Newer systems that support DisplayPort 1.4/HBR3 over USB-C can run 4K 60 Hz and USB 3.x simultaneously even over regular USB-C if the device on the other end supports it, but again you don't have that." Sorry, I re-read the guys post, but I'm not the brightest...Any advice?  PS. If they won't work. Will something like this cable work for me? [URL]
