This is the Ratoc Systems HDMI switcher RS-HDSW41-8K. I am selling it because I accidentally purchased it. A part of the outer box was torn when I opened it, but the product is in good condition and unused. I realized I had purchased the wrong product after opening the box. It supports 8K60Hz/4K120Hz. 4 inputs, 1 output. Everything in the first photo is included. Please consider that this is an unused item, but it has been in someone's possession once before.
