You've got a PS4 Pro, a Chromecast Ultra, and a work laptop all fighting for the one HDMI port on the TV. Every time you want to switch, it's unplug, replug, pray the signal lands. Done.
The Simplecom CM323 slots three sources into one output. Plug them in, hit the button (or let auto-switch grab the active one), and you're watching. No drivers, no software, no fiddling.
It runs full 4K at 60Hz with HDR and 4:4:4 RGB over a 18Gbps HDMI 2.0 link, so your game console's colour depth and motion stay intact. HDCP 2.2 means the latest streaming content plays clean. Older 1080p or 720p gear still works – it's backward compatible down the line.
One thing to know: Apple TV and a few streaming boxes keep their HDMI port 'awake' in sleep mode, so auto-switch may grab them instead of your console. In that case, just press the select button. Ten seconds, sorted.
Self-powered. Plug-and-play. Three cables in, one out, and you never unplug anything again
