General

A hotkey command is a short keyboard sequence for selecting a computer, activating computer scan, etc. The KVM interprets keystrokes for hotkeys all the time. A hotkey sequence starts with a Hotkey Leading Code followed by one or two more keystrokes. After the Hotkey Leading Code is detected, the KVM will interpret keyboard commands until the end of the command.

Note 1: For hotkeys a USB-HID compatible keyboard/device must be connected to the white USB-HID ports.
Note 2: Gaming peripherals or other devices may not work in USB-HID, if so just plug it into one of the blue USB 3.2 Gen 1 ports.
Note 3: Don’t use the Num pad on the right side of your keyboard, use the top row instead.

Possible Hotkey Leading Codes:

  • L-Ctrl
  • R-Ctrl
  • Scroll Lock
  • Num Lock

EDID Information (DP 1.2)

Projectors, Radiology displays, and other “special” devices that are DisplayPort, but not exactly, often do not quite respond all the time. The EDID Learning button at the back of the KVM will memorize an EDID at any point in time and then always present that EDID to the computer.

This prevents the computer from “reacting” when a display is active or inactive and does not depend on any software solutions in the computer.

Note: We still recommend software solutions, that is how it is supposed to be per spec, but not everyone follows spec.

Auto-Learning Button (DP 1.2)

EDID Copy will copy and save the current monitor’s EDID. Auto EDID will intelligently detect a connected monitor’s EDID. Unlike the copy though, the Auto EDID is not saved and will be lost on disconnect or power off. If you’re having EDID issues, try the default setting to “reset” your EDID connections.

EDID Copy Auto EDID Default
EDID Button Hold Time 3 seconds 6 seconds 12 seconds
EDID LED (Upon Hold) Flash Fast Flash Slow Flash Fast
EDID LED (Normal Operating) Flash Twice Flash 3 Times Flash 3 Times

Required Cables (DP 1.2)

  • Display Only Cables (1x per Input, 1x per Output)
    For this model of KVM, you will need DisplayPort 1.2 or newer cables. DisplayPort 1.4 cables will work; however, they are overkill for what this KVM. You might consider DisplayPort 1.4 cables if your KVM will be positioned several feet from your inputs and outputs.

  • Data Only Cables (1x per Input)

    • This is a 5-Gigabit model only.
    • USB-A to USB-B 3.0 (Compatible)

Power Delivery Modes
The default power supply that is included with your L1Techs KVM is a ~20v, 70w, DC Adapter. With this power supply, you have two 70w options available. The difference between A and B is how you would like to allocate amperage to the USB-C ports for power delivery. The options are listed “Input 1 + Input 2” to show how the amps will be split (3A total):

  • 70A - 1.25A + 1.75A
  • 70B - 2.25A + 0.75A

If you choose to buy a more potent power supply on your own, you can have access to the other 2 higher wattage options, 90w or 120w. (~5A total):

  • 90 - 2.25A + 1.75A
  • 120 - 2.25A + 3.00A

USB Modes
It is not possible to support the full DisplayPort 1.4 bandwidth and USB 3.0 5gbps speeds with just one wire. That’s why, on the back of the KVM, you will see a toggle switch in the bottom right. The switch is there to give you the option of what to set bandwidth priority to:

  • U2 (USB 2.0) - Prioritizes Video bandwidth. 480mbps USB speed. Full DisplayPort bandwidth.
  • U3 (USB 3.0) - Prioritizes USB bandwidth. 5gbps USB speed. Uses 25% of total DisplayPort bandwidth.

*USB 3.0 mode could potentially take your max resolution down from 4K @60Hz → 4K @30Hz. The dual monitor version is recommended for higher-bandwidth situations.

Note: Only change power delivery or USB modes when KVM is unplugged.

Required Cables (USB-C)

  • Display & Data Inputs
    For this model of KVM, you will only need USB-C to USB-C input cables. Specifically, you will need USB-C cables that support both USB-C and DisplayPort signals. Improper USB-C cables will not work.
    • USB-A to USB-C (Incompatible)
    • Data Only USB-C to USB-C (Incompatible)
    • Display & Data USB-C to USB-C (Compatible)

Note: All inputs must be from a USB-C port (e.g., MacBook, GPU USB-C, or iPad) unless you are using the L1Techs USB-Combiner to convert the DisplayPort signal to USB-C.

  • Display Only Outputs
    For this model of KVM, you will need DisplayPort 1.4 cables specifically. They are usually not marked physically, so be wary of using DisplayPort 1.2 accidentally. This will cause display issues at high resolutions and Hz.
