I currently have two PCs (work + personal) with a 3-display setup (48" LG C1 TV + 2x 27" LG UHD monitors). The personal PC has a 40-series Nvidia card and the work PC has a 30-series Nvidia card. All displays can do 4K 120 and are G-sync compatible. The C1 TV is only HDMI 2.1 while the LG monitors can do HDMI 2.1 or DP 1.4. My current setup uses a 3-display HMDI 2.1 KVM where I need to do one conversion from each PC of DP 1.4 to HDMI 2.1 with a Club 3D adapter (each card has 2x HDMI 2.1 outputs but equal or more DP 1.4 outputs).
The setup works enough…but there are a couple of issues with the setup where I’m always looking for something more reliable. One issue is that the DP to HDMI adapter isn’t compatible with G-sync (I’d like to utilize it on all monitors). Another is that I’m not entirely happy with the HDMI KVM, it’s prone to intermittent issues while switching and the switch does not work consistently.
So what I’m thinking of doing is going with the 1.4 Display Port KVM Switch - Triple Monitor - Two Computer (10 Gigabit once available again). Then I just need to convert the DP out to the LG C1 from DP 1.4 to HDMI 2.1. I’m going to try a SIIG adapter (CB-DP2611-S1) that supposedly has the Reltek RTD2173 which can do the DP to HDMI conversion at 4K 120 and HDR 10 (not entirely sure if it’ll pass G-sync). But if that adapter doesn’t work, would the L1Techs EDID Feeder DP 2.0 to HDMI 2.1 essentially do the conversion from DP 1.4 to HDMI 2.1?
And I guess the follow-up there is, in general, can I use a DP 1.4 to HMDI 2.1 converter on the output of the KVM to run to the LG C1 and retain all the features I want (4K 120, HDR, G-sync)?
(I also don’t care about passing audio, so it that doesn’t work, no biggie)
