Can I use the CS1824 with a 4K monitor?
Yes. The CS1824 supports both 4K DCI (4096 x 2160 @ 60Hz) and 4K UHD (3840 x 2160 @ 60Hz), so it works with virtually any modern 4K HDMI display.
What does Audio Mixer Mode actually do?
It mixes the audio output from any two of the connected computers at the same time, so you can stay on one computer's KVM focus while still hearing alerts, calls, or notifications from another.
How many computers can I connect?
Up to 4 computers, each connected via HDMI, USB, and audio, with instant switching between them.
Do I need to install any software?
No. The CS1824 works out of the box. Switching is handled via front-panel pushbuttons, hotkeys, or the built-in OSD menu.
Does the USB hub support USB 3.0 speeds?
Yes. The built-in hub runs at USB 3.1 Gen 1 speeds (5Gbps), so shared peripherals like external drives run at full speed regardless of which computer is currently selected.
