DVI splitter

 On AliExpress i found this cheap 2 port DVI splitter. It can send a DVI signal to two output ports.

I looked interesting, i did not test it yet and don't know if i will work for DVI-D signals. A power supply is included. See below for some more photos.

According to the manual the button is for EDID mode. I don't know how it should work. Here is a link to more info for EDID https://www.extron.com/article/uedid
