I’ve been waiting for the HDMI 2.1 KVM to get back in stock, as I previously concluded it would be the best fit for my setup. I have a Work Lenovo laptopn in a thunderbolt dock, with displayport an dhdmi output, a long with my desktop pc with a rtx 3070 (soon to be 50xx).

So I could go for either the displayport 1.4 or hdmi 2.1 kvm.
As I understand it, the HDMI 2.1 KVM will support higher bandwith than the DP 1.4, so it seem like the one.

I am also looking to buy the LG ultragear 45GX950A-B. The max resolution listed in the specs for this monitor is 5120 x 2160 at 165hZ with HDMI 2.1 or DP 2.1…

I read that the HDMI 2.1 KVM supports the following resolutions:

  • 7680x4320@60Hz ( 4:4:4 )
  • 5120 x 2880 @ 60Hz (4:4:4)
  • 5120 x 1440 @ 120Hz (4:4:4)
  • 3840 x 2160 @ 144Hz (4:4:4)
  • 3840 x 2160 @ 120Hz (4:4:4)

What could i expect for a 5120 x 2160 resolution? Have tried looking around in the forum for a clear answer, but i couldnt find one for the 2.1 HDMI model.
I dont know much about DSC, but for higher refresh rate, im all in for it, not sure if my hardware supports it, but i would expect it did (for the desktop and monitor at least. )

When you see this resolution list:

^^ This is not including DSC (Display Stream Compression)

HDMI 2.1 is compatible with this resolution / refresh rate so long as you have DSC.

Make sure you have suuuuper high quality cables. Probably fiberoptic is your best way to go for lossless quality.

I’ll splurge for the highest rated cables according to these forums if I end up buying it :v:
Good to know the fact with DSC. That does make sense. :saluting_face:

Guess theres not much more to it, than make the desicion, or hold out for a DP2.1
