Wireless HDMI G9R Pro Extender Kit 1TX + 4RX - Multi-Screen 165FT

In this review the Wireless HDMI G9R PRO extender kit is evaluated for users who need to send a single HDMI source to multiple displays without messy cables. The bottom line: it is best for conference rooms, classrooms, bars, and retail displays that require easy setup and stable 1080P@60Hz video across several screens. The kit ships pre-paired and delivers near-zero latency streaming across long distances, so the biggest reason to buy is the ability to wirelessly expand one HDMI output to four TVs or monitors with consistent picture and simple plug-and-play operation.

Key Features

• Multi-screen expansion: Sends one HDMI output to four receivers simultaneously so you can mirror a laptop or TV box to multiple screens without a network.
• Long range transmission: Dual-band 2.4GHz and 5.8GHz support up to 165ft in open areas and about 50ft through walls for flexible placement of displays.
• High refresh rate: Supports smooth 1080P@60Hz playback for video and presentations with ultra-low 0.1s latency for tear-free viewing.
• Plug-and-play setup: Pre-paired transmitter and receivers require no drivers or apps, making initial installation fast and straightforward.
• Heat-control technology: The transmitter includes cooling management to prevent overheating during extended use in live events or meetings.
• Portable and adapter included: Includes a USB-C to HDMI adapter for connecting modern laptops and keeps the kit portable for on-site setups.

Who It's For

The G9R PRO suits IT administrators, event technicians, and small business owners who need to duplicate a single HDMI source across multiple displays quickly and reliably. It is ideal for live sports broadcasts, multi-screen menus in restaurants, classroom presentations, and conference-room setups where running long HDMI cables is impractical.

Those who should look elsewhere include users who need native 4K source output from the transmitter (the TX outputs 1080P only) or users who expect TVs to act as HDMI sources because most TVs lack HDMI output capability. Also, if you need distribution over a managed IP network, a networked AV solution would be a better fit.

Pros & Cons

Pros

• Reliable pre-paired connection eliminates time-consuming pairing and reduces setup errors.
• Strong wireless range with dual-band support provides flexible placement of screens up to 165ft apart in open areas.
• Low latency 1080P@60Hz streaming preserves audio/video sync for presentations and live action.
• Includes USB-C to HDMI adapter for modern laptops and a portable design for field use.

Cons

• Transmitter supports 1080P output only, while receivers can decode 4K input, so source resolution must be set accordingly.
• Transmitter cannot be plugged into a TV to act as a source; it must connect to an HDMI output device like a laptop or TV box.

Frequently Asked Questions

Can this kit stream to more than four screens?
Yes, the system supports additional receivers under certain conditions to reach up to six displays when using two mobile receivers in addition to four dedicated RX units.

Can the transmitter be plugged into a TV?
No, the TX must be connected to an HDMI output device such as a laptop or TV box because most TVs do not provide HDMI output functionality.

What power is required?
Both transmitter and receivers require a stable 5V/1A power supply; powering the TX from a laptop USB port may need the laptop to be plugged into mains for reliability.
