HP Recommended
Product: 15-cx0811no
Operating System: Microsoft Windows 10 (64-bit)

I know this is difficult question, but can my laptop (HP Pavilion Gaming 15-cx0811no, from 2018) do more bandwidth via it's USB-C port (with 1 USB 3.1 Type-C™ Gen 1 (Data Transfer up to 5 Gb/s, Power Delivery, DisplayPort™ 1.2, HP Sleep and Charge)) than through it's HDMI 2.0 port? (Specs say it's HDMI 1.4 port, but it's 2.0 for sure). 

 

I have 32" 4K 10bit monitor, that can support 4K 60hz 10bit with DisplayPort 1.2 and 4K 60hz 8bit with HDMI 2.0. Im using HDMI 2.0 now, and it's working well but it would be nice to try 10bit colours.

 

I don't have the needed USB-C to DisplayPort cable yet, but I read elsewhere that video signal via USB-C (alt mode) is somehow limited compared to normal DP bandwidth, but with Thunderbolt 3 support and cable it should exceed it easily. But im not sure about all this. Does my laptop support Thunderbolt 3 then? Probably not, because it's not mentioned in the specs.

 

Im also aware that consumer GPU's didn't support 10 bit colours before (for OpenGL apps like Photoshop), but they should have working drivers for GTX 1050 now.

 

But this is not super important, im fine with 4K 60hz 8bit with this "old" laptop.
