YINGHUA Wireless HDMI KVM Extender 200M 1080P 1 TX 4 RX

Wireless HDMI KVM extender 200M 1080P

This wireless HDMI KVM extender transmits 1080P video and USB keyboard or mouse signals up to 200 metres between a single transmitter and up to four receivers. It suits installers who need to share a PS4, camera or PC display across multiple screens without running cables. The system also supports a multi-to-one switch mode where four transmitters connect to one receiver.

Splitter and switch modes with USB control

The bundled one-to-multi splitter mode lets one transmitter drive up to four receivers for simultaneous screen sharing. The multi-to-one switch mode allows four transmitters to share a single receiver. A USB port on each unit accepts a keyboard or mouse only; it cannot be used for storage, cameras or other peripherals. IR remote control functions only in a one-transmitter-to-one-receiver configuration.

Installation notes and common issues

Both transmitter and receiver must be powered and paired; neither unit works alone. Adding receivers reduces the effective wireless range, and walls or obstacles shorten it further. For best results through a single wall, use one transmitter with one receiver. The USB port rejects non-input devices, which is the most frequent setup mistake.
