Need help with external monitor during live boot

I am going to be cloning multiple laptops at the same time using Clonezilla. I need to have their clamshells closed so they can sit on top of each other. I have a KVM switch connected so I can do 4 laptops at the same time. I have an external monitor attached to the KVM switch to watch the laptops progress as they boot Clonezilla live. I have tried every Clonezilla boot option but none of them seem to allow me to use an external monitor to view the Clonezilla boot progress. Can I adjust the SyslinuxCFG file to load video drivers for the external monitor so it will work as soon as the first Clonezilla screen appears?
I believe so. You can put parameter like "video=VGA-1:1280x1024" in the boot parameters.

@steven_shiau Could you please make Clonezilla wake an external monitor that is in power saving mode, and mirror what is happening on the laptop computer to the external monitor? If someone has a broken monitor but still wants to use clonezilla, then the user needs to see the output. Don't extend the screen, but only mirror. If the user wants to change it so it's not mirrored, perhaps then, for now, a command could be entered in the shell. But by default, I think clonezilla's output should be mirrored to the hdmi port.
Sure. Do you know how to do that? I can not find the method to mirror the console, text mode.

Oh.. So you need to control the underlying operating system, eh? I thought maybe you had that built-in functionality already.
I guess there's a program called "xrandr"

and a program called "screen"

Again, it sure would be nice if Clonezilla could output text to the external monitor through hdmi by default, in case my computer screen breaks. Any updates on this?
BTW, you can remove "nomodeset" from the boot parameters so that your console can be mirrored to the external monitor.
