Graige Wireless HDMI Transmitter and Receiver 1000 FT

This wireless HDMI kit from Graige lets you stream 4K video and audio from HDMI sources to displays across rooms, useful for home theater setups, presentations, and surveillance monitoring. It supports long-range transmission and includes IR pass-through so you can control the source device from a different room while maintaining a low-latency 1080p 60 Hz option for smoother motion when needed.

Key Points

The system transmits audio and video from HDMI-output devices such as set-top boxes, DVD players, PCs, and game consoles to HDMI-input displays like TVs, projectors, and monitors. Transmission supports progressive scan formats including 2160p, 1080p, and 720p, while interlaced formats are not supported. According to the manufacturer, the unit uses hardware decoding to deliver 4K at up to 30 Hz, and it can provide 1080p at 60 Hz for reduced latency and more responsive playback. The kit includes one transmitter and up to three receivers to distribute a single source to multiple rooms.

Benefits

Built-in IR extend functionality means you can operate the source device from another room using your existing remote control, which is practical for concealed set-top boxes or stereo racks. The dual cooling approach combines a near-silent fan with large nano-sprayed aluminum heat plates, which helps manage temperatures during extended use and may extend device longevity according to the manufacturer. Multiple selectable frequency bands reduce the chance of interference in crowded wireless environments and allow simultaneous transmissions for different signals.

Usage Recommendations

For best results place the transmitter and receivers with clear line of sight and minimal obstacles. Use the HDMI loop-out on the transmitter to drive a local display while sending the same feed to remote receivers. Keep in mind that while 4K at 30 Hz is supported, higher refresh rates at 4K are not available, so consider using 1080p 60 Hz when low latency is a priority. Also consider that performance can vary depending on building materials and wireless congestion in your area.
