GL-RM1 Comet - How to show multiple displays?

Hello: I recently bought a GL-RM1 Comet to connect from my home computer to my work computer - both of which have multiple displays.

Whenever I’m using either computer, I want all displays to show the content from that computer. But when I connect with my Comet (which works fine otherwise), it only shows the display from one of my work’s displays.

Is it possible to add more than one remote-controlled display using Comet KVM? If so, how is this done?

Thanks for any assistance provided.

Theoretically, Comet is acted as a monitor in your remote device, so multiple screen display might cannot be achieved and there is noway to switch the display from varied displays.

Sorry, I don’t think I understand what you mean - you’re saying it’s theoretically possible, but then you say it cannot be achieved?

You can think of Comet as an additional monitor for your computer, with the key difference being that you can access it remotely. However, just like a physical monitor can’t display the screen of another monitor, Comet operates independently in that sense.

It’s important to note that Comet is not a KVM switch, which is designed to receive and manage multiple displays. That said, some customers have successfully used Comet in combination with a KVM switch, and this setup may meet your needs. You can refer to the post below for more details. Please note, however, that we can’t guarantee the compatibility or performance of such a configuration

Thanks for the clarification! I appreciate it. Unfortunately I think that means Comet isn’t for me. Thanks anyway!

On Windows this is possible but finicky.

First or best is to know the port order of your gpu, this way you will know if monitor 1 is 1, and monitor 2 is 2, this is necessary to avoid conflicts when going advanced as stated here under about virtual monitors.

Virtual monitors:
Windows merely saves monitor states when one monitor connects the state is saved to your main/active monitor, this is maybe not that important for you but will be if you spawn virtual monitors (i.e artemis/apollo, dummy plugs for game streaming), you can also make others shutdown as soon the virtual monitor connects, for dual monitors it is called only view on (1-2) and for more it is called: shutdown monitor for this screen

Inside the Windows settings (I assume win11), you have a section for the screens, just set your main screen to duplicate and all screens render the same output, theoretically you could set the kvm as default and duplicate them to other monitors.

Cerveats:

  • it will not work nicely if other monitors have different mixed resolutions, you really want to match this or you will have issues and glitches especially with the mouse, as for refresh rate it can downgrade it to the lowest available max refresh rate of one of your monitors.

  • it is not wise to use the kvm on hdmi 1, unless you use displayport, otherwise your bios will never project the boot screen on the monitor unless windows had been booted.

Display ports have always higher boot priority than hdmi, and only when windows has been booted the other monitors become visible.

Between hdmi the priority goes also as 1-3 (as example).

^ alot of these black screen issues has to do with these priority issues, a bios can only load one monitor, and only windows can load more, so if there is a bootloader password screen you will get a black screen.

also sometimes you need to manage screens on the kvm, and sometimes on the monitor it really depends on what is going on, sometimes win+p helps to switch screen modes I often use arrow down and press enter if for some reason it is impossible to control due to complexity.
