Long-range wireless HDMI extender kit

The StarTech ST121WHDLR transmits an HDMI signal up to 656 ft (200 m) over the 5 GHz band. It supports 1080p at 60 Hz and LPCM 5.1/7.1 audio for full HD viewing. The kit includes transmitter, receiver, IR blaster, IR receiver, HDMI cable and two universal power adapters. Rack-mountable plastic housings suit permanent installs.

Replaces long HDMI cable runs

Instead of pulling expensive shielded cables through walls or conduit, this kit sends video wirelessly across large venues, classrooms or digital-signage networks. The jump is worth it when cable length exceeds reliable HDMI limits or when installation labour and material costs outweigh the extender price. No daisy-chain function is provided, so each link is a single point-to-point connection.

Handles 1080p sources with IR control

The extender comfortably drives 1920 x 1080 at 60 Hz plus 720p, 1080i and legacy VGA through SXGA resolutions. It runs out at higher resolutions such as 4K or high-refresh 1080p beyond 60 Hz. Infrared pass-through lets you control the source from the display side. Operating range is 0-40 °C with 25-60 % humidity.

Questions about this item

What mounting hardware is included for the 1.00" x 2.50" x 4.50" transmitter and receiver units?

The kit includes two sets of mounting hardware designed for the transmitter and receiver, allowing you to secure each 1.32 lb unit to a wall or rack as needed.

The kit includes IR blaster and receiver cables; how should these be connected to the IrDA ports for remote control passthrough?

Plug the 3 ft IR blaster into the transmitter's IrDA output and the 3 ft IR receiver into the receiver's IrDA input, then position the receiver eye with line-of-sight to your remote.

The universal power adapters supply 5 V DC at 2 A; what ongoing maintenance do they require?

No scheduled maintenance is required; simply keep the adapters and unit vents free of dust and operate within the 0 to 40 °C range to ensure reliable power delivery.
