[Official] L1Techs KVM FAQ -- Ultimate Guide & Help!

Would the USB-C KVM Switch v3 (with USB Power Delivery / 135watts) work for this Setup

Laptop 1: Work Laptop Dell Precision 3580
Laptop 2: Person Asus Zephyrus G16

Monitor: Dark Matter by Monoprice 34in Ultrawide Monitor - 3440x1440p, UWQHD, 165Hz

Laptop 1 (Work Laptop) I want to hook up to support USB C PD and have everything connected to it via the USB C Connection

Laptop 2 (Personal Laptop) Same as above but instead of USB C PD I will be using the power adapter that came with the laptop so I can use the 4070 GPU in the laptop but will be passing Video and Keyboard/Mouse over the KVM.

I want to make sure I will at least get 144HZ from the monitor to my laptops (I know that’s what the KVM is rated for at 1440P) and if I get 165HZ that would be great.

Getting a new office setup done and want a quick and easy way to swap between the 2 laptops but the L1Tech KVM is the only one that I can find that supports both the resolution and the refresh rate so just want to make sure what I mapped out above would work before I buy the KVM.

1440p 165hz should be no problem thanks to DSC.

This whole setup seems fine. Make sure you have hight quality thunderbolt and displayport cables.

Disable deep sleep mode on the monitor if it has it.

I tried the UGreen bididrectional „8K“ USBC to Displayport 2.1 cable and can confirm that it is in fact bidirectional and has enabled VRR, but poorly insulated, as it tends to artefact on my setup.

Hi L1 Team. Is there any way to have a 4pc USB C or USB C+DP kvm? I have a couple laptops and a desktop for 1 monitor setup.

I can also confirm that the CableMatters USB-C to Displayport 1.4 Cable works bidirectionally without it saying it does with Flawless VRR and it fixed my flickering and blackscreen issues, although at the trade-off of 120Hz max on WQHD, just putting it out there for someone else with the same issues

Unforunately not at the moment

Got it. If a 4 PC USB C KVM is not on the table, could someone use the USB C combiner to connect a USB C PC to the DP DVM? Essentially, using the combiner in a “reverse” direction.

Really random question. I have a PC that outputs to 2 monitors (a normal monitor and one companion touchscreen). Only the normal monitor is connected to a KVM via DP. I don’t want the companion monitor connected to a KVM.

When I switch PCs on the KVM, my PC reconfigures the companion monitor as the only monitor. It’s as if the normal monitor no longer exists to my PC. Is there a way to prevent this from happening? I am using the 4 PC single monitor DP KVM.
