Gave up trying to use the Multi Screen option in Windows 11 with a GL-RM1, all I could get was to Extend Screen which is no use. It just won’t work and I’ve tried every combination and dumbing down my graphics and custom EDID’s. My current solution is to tell the graphics card to output only to monitor 1 and I switch that monitor off when I’m away. That then lets it switch to the KVM and works well. At the moment I use a Homekit Smart plug and I can use iOS to remotely switch the monitor off but I’d rather have a single interface solution.
I’m using an ATX Board to power on the PC remotely but I don’t need the Reset option. Can anyone tell me what current the ATX Board Reset Pins can handle? I’m planning to use the Reset Channel to switch a relay to toggle the power state of the monitor. I suspect it’s not capable of more than a few mA but the spec would be useful so I can build a logic board if needed.
I’m aware of the FingerBot but I haven’t had a good experience with similar products so wouldn’t rely on that to toggle the monitor power state. Another option would be to dismantle a FingerBot and use it to toggle a relay.
If your Windows does not display the mirror settings, there is only one possibility: you have connected the monitor and the KVM to different graphics cards. You need to plug them into the same graphics card.
Regarding ATX boards: the maximum output mA is approximately 15mA to 20mA. Additionally, in case you need to use the relevant commands for the ATX board:
My graphics card has tripple monitor support. The KVM is set as monitor 2 and my other monitor is number 1. The chip in the KVM only supports 30hz at the resolution I use. I’ve tried setting the resolution and frame rate lower and then cloning the settings so both are identical. It’s an nVida card and I’ve dumbed everything down so no HDR, no high bit depth etc. Windows will not accept mirroring the display, just extending it. Only option is to power off monitor 1 when I want to use the KVM which is fine, it works and I don’t have to sacrifice the resolution or frame rate. I have a GL-RM10 on order as I liked the HDMI passthrough option. Unfortunately that appears to have the same chip and won’t support my resolution at 60hz so I’m trying to get everything setup by trying to utilise the ATX board Reset as a switch for my monitor. The current GL-RM1 will be going on a headless server so I’m just using it on my main PC in the meantime to get everything the way I want it. I’m not interested in Mirroring my display any more as the frame rate support is too much of a compromise so I’m trying to design a logic board, triggered by the ATX Board to switch a power relay.
