GL.iNet Comet (GL-RM1) Remote KVM Over Internet
Bottom line: The GL.iNet Comet Remote KVM Over Internet ($99.99 on Amazon as of 2026-10-07): BIOS-level control: reboot, power on, and install an OS without the host OS running; main trade-off: 4K tops out at 30Hz, so motion-heavy work looks less fluid than 60Hz.

Manufacturer description
The GL.iNet Comet (GL-RM1) is a hardware remote KVM that lets you control a computer's keyboard, video, and mouse over the internet, even when the operating system isn't running. You can reboot a machine, enter the BIOS to install an operating system, and power on computers remotely, so you don't have to go to the server closet or data center. Video streams at up to 3840x2160 at 30Hz with low latency. Encoding is done in hardware with H.264, and remote audio output is included. The target computer needs no extra software. Connect the Comet to a laptop, desktop, or server, then open a session…
SpecPicks Verdict
