How to make an independently switch video sources on a DisplayPort 1.4 multi-monitor sharing KVM switch

So many users asked if they can do independently video switching or video parking ( assign and lock a shared monitor to get from one of the connected systems).

The function is called "asynchronous switching" the video on a multi-monitor sharing KVM switch.

In order to do it on a KVM switch, the KVM switch MUST meet the following qualifications:

  1. have built-in full-time video EDID emulation and EDID feeding on the hardware PCB to each channel connected to every connected system, and to each video output to the shared monitors.

  2. Can control the switching via Keyboard hotkeys, IR remote, or serial console (via the RS-232),

  3. At least two physical video output ports ( 2 or more video-sharing ports)

The video shown in this post is an example using a dual-DisplayPort 1.4 sharing DDM-class KVM switch.

The video shown is using hotkey commands.

<hotkey><hotkey><v><x><p><y> for having video x monitor showing video source from the system connected to channel y. x=1 or 2, y=1 or 2 (for 2-system KVM switch), y=1,2,3 or 4 (for 4-system KVM switch).

release the video parking /lock using the following hotkey commands

<hotkey><hotkey><v><x><p><0> accordingly.


Why your KVM switch is required to have built-in EDID emulation and EDID feeding to make the independent video switching and parking/ locking meaningful?

If the KVM switch does not or can not keep the correct EDID communication to the monitor and to all connected systems of a KVM switch, then when shared monitors are switched away from the current connected system, the video ports of the old connected system would be terminated from outputting correct video signals unexpectedly.

As the result, even if the KVM switch can let you do independent video switching, you will not get the correct video signals and contents from new or old connected systems. It could be showing a blank screen or a screen with randomly assigned contents.

So, a KVM switch equipped with full-time EDID emulation and EDID feeding to all connected systems is not only for making a fast switching between/among connected systems' video, but also is for the independent video switching to become meaningful and useful.


What applications or user groups will get the most benefits from independent video switching and full-time EDID emulations/feeding included within the advanced class KVM switches?

  1. Software developers, Games developers, Software testing and evaluation.

  2. Operation control and monitoring center, control desk console controllers.

  3. Manufacturing Automation control room operations,

  4. Data Center control room operation desks,

  5. Professional AV (audio/video) creation and edition,

  6. On-line technical support operation,

  7. WFH (Work From Home) workers who are required to do multi-tasking or get balance between job work and gaming.

  8. Whoever wants to make his work follows smoothly, changing the paths easily.

Again, you, the user, the human being should be the center of all the hardware devices you have (or the company gave you). If the combination of existing hardware devices can not serve you well, replace them to fit your needs.


The Perspective Goal of ConnectPRO

The hardware and devices we developed should serve the users and make their lives easier, rather than the other way around. If the combination of existing hardware devices isn't serving users well, it's important to explore other options that better fit users' needs. It's important to prioritize the users' own needs and preferences as final users, rather than simply accepting the limitations of the devices currently have . By doing so, we can ensure that we are using technology in a way that maximizes the users' productivity, comfort, and overall satisfaction.
