RATOC SYSTEMS RS-BDHDSW21-8K Bi-directional HDMI Switcher

I've used this for about 3 years, but I'm selling it due to moving and reorganizing my PC environment and equipment.

This is a bidirectional HDMI switcher RS-BDHDSW21-8K made by RATOC Systems, compatible with ultra-high resolutions like 8K60Hz and 4K120Hz.

It can be used bidirectionally, either to switch between 2 PCs/game consoles on 1 monitor (2 inputs, 1 output) or to switch 1 PC to output on 2 monitors (1 input, 2 outputs), making it very convenient for building a custom multi-display environment.

[Product Condition]

Operation has been confirmed.

There are minor scuffs on the surface of the unit due to normal use, but no noticeable major scratches or rust on the terminals.

The outer box and instruction manual are not included. (The instruction manual can be downloaded as a PDF from the manufacturer's official website.)

[Included Accessories]

HDMI Switcher Unit x 1

Dedicated AC Adapter (5V/0.6A MicroUSB connection) x 1
*Everything shown in the photos is included. Please prepare your own HDMI cables.

[⚠️ Please Read Before Purchasing (Important)]

To output and switch at high resolutions/refresh rates like 8K60Hz or 4K120Hz, all connected input devices, monitors, and HDMI cables must support Ultra High Speed HDMI (HDMI 2.1 standard).

Symptoms such as no video display or blackouts when using non-compliant older or low-quality cables are rarely due to defects in the switcher unit itself. Please ensure your own equipment and cable environment are fully compatible before purchasing.

As this is a used precision electronic device, please refrain from purchasing if you are looking for a perfect, like-new condition. Bidirectional HDMI switcher compatible with 8K@60Hz, supports 2-port connection.
