I look for an 2nd Opionion if I found the Manufacture of the HDMI Matrix Switch

[Boy2006]

Hi
I love Delock Products since the normally import Chineese Pc Stuff into Europe who are perfect for our nerds. Stuff normally sold on Aliexpress.
I bought there HDMI Matrix Switch. Since I bought the wrong Thinkpad Dock I could use only one HDMI Port currently.
This is the Switch: https://www.delock.de/produkt/66454/mer ... anguage=en
Normally when there is a "Service" Port I look for the Original Manufacture to see if the offer some Updates since Delock sadly dont offer them.
So ofter Googeling a while I found the "German Company" who claim to manufacture it: https://feintech.eu/collections/hdmi-ma ... tor-scaler
Hmm normally the stuff come from a Chineese Company. Ok ok the offer some Updates how it seem.
Does anyone recognise the Switch and know the original Manufacture if its not the German?
Thanks!

EDIT: I found a Chinese Company who offer them (to): https://www.bungpung.com/en-nz/products ... -extractor
