You have a laptop, game console or media PC in one room, and screens in several others. The Coolpie Wireless HDMI Transmitter and Receiver, model GT-HDWL-150B, takes one HDMI input and mirrors that picture and sound to four separate displays without running cable through the wall.
Each receiver needs its own power outlet at the television, so count your wall sockets before buying. The transmitter also needs power at the source.
The kit supports 4K input and outputs 1080p at 60Hz. If your television is a 4K panel, the receiver downscales the signal rather than passing it through, so we'd skip this kit if native 4K at every screen is non-negotiable for you.
How the signal travels to each screen
Everything rides a 5.8GHz single-band link with external antennas, and the transmitter and receivers pair themselves once powered. There is no app to install, no Wi-Fi network to join and no Bluetooth pairing, which matters when the person at the other end is not technical.
Coolpie rates the reach at up to 100 meters (350 feet) with clear air, or 50 meters through solid barriers, and cites latency near 0.1 seconds. Treat those as line-of-sight ratings. Walls between rooms will shorten usable distance, so a room-to-room run through brick is a real question mark.
Check the HDMI port on each destination. A television with only coaxial or older composite inputs will need an adapter, and the kit has no pass-through for a local source at the receiver end.
Where this kit earns its place
A bar, restaurant, classroom or sports room with several televisions showing the same feed is the natural fit, because each receiver has its own place in the room and its own power point. The aluminium body and vented housing are built for long sessions rather than a quick demo.
At $189.99, the kit sits below its typical price over the last 90 days of $219.23, and it matches the lowest price we have recorded. That is the strongest case for this set: four receivers and a transmitter for less than the usual run rate.
We'd pass if you need 4K at every display, if your screens lack HDMI, or if you want to place the transmitter and farthest receiver through several walls. Confirm the port count on the source device, note how many outlets sit near each television, and settle how the room clears before you commit.
Four receivers plus one transmitter for $189.99, which matches the all-time low we have seen.
Typically $219.23 over the last 90 days, so the current price is $29.24 below that run rate.
