HOLEPLUS T81 Wireless HDMI Extender 1080p/60Hz

HOLEPLUS T81 is a compact plug-and-play wireless HDMI transmitter and receiver kit that streams video and audio from laptops, set-top boxes, and cameras to TVs, projectors, or monitors up to about 100 ft away.

The T81 wireless HDTV extender eliminates messy cables by creating a direct HDMI bridge between a source device and a display — no apps, no Wi‑Fi network, and no Bluetooth pairing required. Equipped with dual-band (2.4G/5G) processing and an LDS antenna, the kit supports smooth, low-latency transmission with 4K decoding and 1080p/60Hz output. It ships with adapters to fit Micro/ Mini HDMI and USB Type-C sources, plus a randomly matched white or black USB cable for power.

How does the T81 make setup faster and neater?

Setup is immediate: plug the transmitter into your source’s HDMI output (adapters included if needed), plug the receiver into the display, and power both units via USB. There is no network configuration, no passwords, and no companion app to install, so you avoid common wireless setup headaches.

• Plug-and-play connection with no software required
• Includes Type-C and Micro/Mini HDMI adapters for broad compatibility
• Random included USB Type‑A to Type‑C power cable (white or black)
• Small footprint keeps desks and AV racks tidy

What kind of picture and audio quality can I expect?

The T81 decodes 4K sources and delivers up to smooth 1080p at 60Hz to most HDTVs and projectors, giving clear, colorful images for presentations, movies, or gaming. Audio is transmitted alongside video for synchronized playback on the connected display or sound system.

• Supports 4K decoding with 1080p/60Hz output
• Low latency transmission (<0.01s nominal) for near real-time playback
• Stable, high-performance signaling for clear video and synchronized audio

How far will the wireless signal reach and how reliable is it?

Using dual-band 2.4G/5G chips and an LDS antenna design, the kit achieves reliable wireless range up to approximately 100 ft (30 m) under open-line conditions. Signals can penetrate typical walls and ceilings, though distance and throughput may vary depending on building materials and interference.

• Up to about 100 ft (30 m) line-of-sight range
• Dual-band transmission helps avoid congestion and improve stability
• Signal resilience through common obstacles, with expected variations in challenging environments

Which devices and situations is the T81 compatible with?

The T81 accepts HDMI sources from laptops, PCs, cameras, TV boxes and set-top boxes and outputs to HDTVs, projectors, and monitors. Included adapters broaden compatibility, but devices must support HDMI output on the used port.

• Works with PCs, laptops, cameras, TV/set-top boxes, and many tablets that provide HDMI output
• Connects to HDTVs, projectors, monitors with HDMI input
• Includes Micro/Mini HDMI and USB-C to HDMI adapters for varied hardware

Who is this for: The HOLEPLUS T81 is aimed at professionals and home users who want a quick, cable-free way to mirror or extend screens — ideal for conference rooms, classrooms, trade-show booths, home theaters, and live events. It suits users who need fast deployment, clear video at 1080p/60Hz (with 4K decoding capability), and consistent wireless range without joining a local Wi‑Fi network.
