What to know before buying

Listing details to confirm

Listing details are inconsistent or unconfirmed: the title describes a USB-C wireless HDMI set and claims 328FT/100M, while body details also describe 4K output and give mode-specific 1080P refresh rates. The 4K output wording does not establish that all modes run at 4K. Check the selected source device, required output mode and exact package listing. The claimed maximum range requires an unobstructed path, and the listing says wall obstructions affect range and speed.

Who is it for?

A good fit for

Phone or computer users who want to mirror or extend a screen to an HDMI display without a long HDMI cable.
Presentations or viewing setups where the transmitter and receiver can operate in the same unobstructed space.
Buyers willing to confirm device compatibility and choose between the listed point-to-point and WiFi modes.

Less suited to

Setups that need dependable transmission through walls or between separate rooms.
Buyers who require 4K at a specified refresh rate, since the listing's mode-specific refresh rates are given at 1080P.
Owners of Lightning iPhones, Galaxy A or F series, Moto G, or Edge Neo/Lite models, which the listing says are unsupported.

Frequently asked questions

Does the S9 Pro need Wi-Fi to mirror a screen?

The listing says its plug-and-play point-to-point mode does not require Wi-Fi. It separately describes a WiFi mode, so confirm which mode fits your setup.

Does it provide 4K at 60Hz?

The listing claims 4K output but specifies 1080P/60Hz in point-to-point mode and 1080P/30Hz at the receiver in WiFi mode. It does not substantiate 4K at 60Hz.

Will the claimed 328 ft/100 m range work through walls?

The claimed maximum is for an unobstructed, interference-free environment. The listing warns that walls and other obstacles can reduce range and speed and says use between rooms is not recommended.

Which phones are listed as incompatible?

The listing names iPhone models with Lightning, Galaxy A and F series, Moto G, and Edge Neo/Lite models as unsupported. Confirm your exact device and its USB-C video capability before buying.
