A KVM switch designed to let two computers share a single monitor and USB peripherals, with support for smooth 4K display when everything is compatible. Free up desk space and stop swapping cables, ideal for office multitasking or a dual-PC streaming and gaming setup. How reliably will CMSTEDCD HDMI KVM Switch handle high-resolution video and multiple USB devices?
⚡ At a Glance
- • Image Quality: Supports up to 4K@60Hz when both source, HDMI cable and monitor support 4K@60Hz, colours display vividly
- • Best for: Office users, streamers and gamers who need one monitor and shared peripherals across two PCs
- • Not ideal for: Setups that rely on keyboard hotkeys or require high-draw USB devices over 10W
Two-port HDMI KVM shares a single monitor and up to four USB 3.0 peripherals, switching via a wired desktop button. External 12V power keeps USB peripherals stable and supports higher bandwidth connections for reliable use.
Crisp 4K visuals - with support for 4K@60Hz HDMI
Supports resolutions up to 4K at 60Hz when both connected computers, HDMI cables and the monitor support 4K@60Hz. HDMI cable length should be kept to six feet or less to ensure reliable signal transmission.
Sharper images for video playback, editing and gaming when every link in the chain is 4K-capable. Expect more vivid colours and smoother motion in supported setups.
Faster peripheral transfers - with four USB 3.0 ports at up to 5Gbps
Four USB 3.0 ports deliver transfer rates up to 5Gbps and remain backward compatible with USB 2.0 and 1.1. Note that devices drawing more than 10W are not supported.
Quick file transfers and responsive mice or keyboards for everyday tasks, while mass-storage and webcams that stay within power limits work well. Avoid relying on high-power USB devices without checking draw limits.
Stable peripheral power - thanks to the external 12V adapter
External 12V power supplies USB peripherals independently of host USB current, avoiding reliance on limited host power. The desktop-wired controller includes an LED indicator to show which source is active.
Reduced disconnects and steadier behaviour for standard peripherals like keyboards, mice and printers. Some power-hungry hard disks and cameras may still be incompatible despite the external supply.
