Combo USB-C Power Delivery & DisplayPort 1.4 KVM - Triple Monitor

Combo USB-C Power Delivery & DisplayPort 1.4 KVM 

With previous models, you would have to choose: DisplayPort KVM, or USB-C KVM? What if I have both? You could put together a solution, but it’s kind of expensive and inconvenient. Using a MAC with one of our DisplayPort 1.4 KVMs would mean that you lose the power delivery option that people really enjoy from our USB-C KVM. Introducing: The COMBO KVM. 

Listen. No KVM is perfect BUT our customers tell us -- The L1Techs KVMs are pretty darn good. 

Example Setup: 

PC 1 (DP Only Desktop) 

Input 1: DP 1.4 -> DP 1.4 

Input 2: DP 1.4 -> DP 1.4 
Input 3: USB-C Combiner* -> Bottom USB-C 

PC 2 (M1 Mac) 

Input 1: Moshi USB-C** -> DP 1.4 

Input 2: Moshi USB-C** -> DP 1.4 
Input 3 -> Bottom USB-C*** -> USB-C 

Monitors 

Output 1: DP 1.4 -> DP 1.4 

Output 2: DP 1.4 -> DP 1.4 

SEE NOTES 

DisplayPort Only PC Compatibility* - L1Techs USB-C Combiner 

To use the bottom USB-C port with a DisplayPort only device you WILL need the L1Techs USB-C Combiner. If you want to use a MAC + PC, typically you would have to use a DisplayPort KVM & convert the USB-C device output to DisplayPort. Cables like the Moshi USB-C to DisplayPort cable cannot be flipped around to be a DisplayPort PC output to USB-C KVM input. Therefore, if you want to use this L1Techs combo KVM with a DisplayPort device, the best solution we offer is the USB-C Combiner. 

DisplayPort Inputs for USB-C Device** - Moshi USB-C to DisplayPort 1.4 

If you have a USB-C device (e.g. MAC), every input besides the bottom USB-C will require a USB-C to DisplayPort 1.4 cable. We highly recommend Moshi as they have performed the best in our testing.  

Display & Data USB-C to USB-C (Bottom ports)*** 

The KVM uses USB and DP input on the same USB-C connector. It is not thunderbolt, but often thunderbolt ports can fallback to USB + DP on one USBC connection. Sharing USB and DisplayPort on the same USB-C cabling will limit the total bandwidth of the cable. You will need a display & data capable USB-C to USB-C cable for your USB-C hookup (e.g. MAC). 

Features: 

• Two DP 1.4 connections from each computer (up to 4k/120hz or 8k/30hz). 

• Lower resolutions + Higher framerates possible e.g. 144hz @ 1440p work just fine because of full DP 1.4 compatibility. (Overclocking not supported) 

• DisplayStream Compression Supported 

• Intelligent EDID Engine for HDCP Rekeying (computers know when the port is inactive. Check out the Level1Techs repeater if you need monitor emulation). 

• HDCP Passthrough Supported (maintains HDCP signal integrity) 

• Intelligent USB HID passthrough (includes work-arounds for known problematic devices) 

Import Usage Information 

MAC 2 External Monitor Limit 

MACs with an M2 Pro chip have a limited amount of 2 monitors they can be connected to!! If you buy this KVM to hook up your MAC, make SURE it can connect more than 2 external monitors! For up to 4 external monitors, you will need the M2 Max chip. There is a workaround with DisplayLink drivers and cables, but you will be severely gimped with resolution and refresh rate. 

According to MACWorld, here are some MACs and their external monitor capabilities: 

• M1 MacBook Air: Maximum one external display 

• M2 MacBook Air: Maximum one external display 

• M2 MacBook Pro: Maximum one external display 

• M2 Pro MacBook Pro: Maximum two external displays 

• M2 Max MacBook Pro: Maximum four external displays

U2/U3 Switch 

Unfortunately, it is not possible to support the full DP 1.4 bandwidth AND USB 5gbps speeds with just one wire. So, we give you the option. At the back of the KVM is a switch that lets you pick between USB3 and USB2 speeds. This switch prioritizes DisplayPort bandwidth or USB bandwidth, in other words.
