LG DT255W-H Wireless HDMI Extender 1080P 98FT/30M Kit

LG DT255W-H Wireless HDMI Extender Kit

The LG DT255W-H is a wireless HDMI extender kit designed to transmit 1080p video and audio from a source device such as a laptop, PC, or camera to a display like a projector, monitor, or HDTV. It targets users who want to eliminate long cable runs in home, classroom, or meeting-room environments. The compact transmitter and receiver units connect via HDMI and draw power from USB-A ports on the host devices. No driver installation is required for operation.

1080p at 98 ft line-of-sight range

The single specification that determines suitability is the maximum wireless transmission distance of 98 ft (30 m) for 1080p Full HD signals. This range applies only when there are no obstacles such as walls or floors between the units; obstructions can reduce the effective distance to 32 ft (10 m). The system operates on a 5 GHz frequency band for lower latency. Buyers needing 4K resolution, longer range through walls, or support for HDCP 2.2 protected content should consider other solutions.

Plug into HDMI and USB-A on both ends

Each unit requires an HDMI input or output and a USB-A port for power, so the source must provide both an HDMI output and a powered USB-A port, while the display needs an HDMI input and a USB-A port or a separate USB power adapter. The kit includes HDMI, component, and composite interfaces on the transmitter side for legacy source compatibility. It frees up floor space by removing the need for in-wall or across-room HDMI cabling, but it does not carry Ethernet, IR return, or USB data back to the source.
