What to know before buying

Listing details to confirm

Listing details are inconsistent on video modes: the title and main feature claim 8K@60Hz and 4K@120Hz, while another section also lists 4K@144hz and other modes. The listing also alternates between saying a power cable is included and merely requiring a DC5.5mm cable, while confirming that the power adapter is not included. Confirm the exact mode and cable supplied for the selected listing. The stated installation guidance is input HDMI cable within 1m and output HDMI cable within 2m. A 5V/1A or higher power source is required.

Who is it for?

A good fit for

People with up to three HDMI sources and one TV, monitor or projector who want to select which source is displayed.
Buyers considering high-refresh-rate gaming setups who can verify the required resolution and refresh rate across their source, display and cables.

Less suited to

Anyone who needs automatic input switching when turning devices on or disconnecting a source.
Setups that require confirmed 4K at 144Hz without first resolving the listing's conflicting mode claims.

Customer feedback reports easy setup and solid build quality, while functionality, device compatibility, image quality and switching speed receive mixed reactions. Some feedback describes compatibility problems with Nvidia Shield Pro, imperfect results at 4K 120Hz or 144Hz, and delays switching inputs. For buyers relying on high-refresh-rate modes, those reports make it especially important to confirm the desired mode and compatibility with the full setup. Remote-control and value opinions are also mixed. The overall rating distribution leans positive, but includes a notable one-star share and does not explain individual experiences.
