Review on 🔀 CABLEDECONN 8K DisplayPort Switch Bi-Directional Converter for Multiple Sources and Displays, supporting 8K@30Hz and 4K@120Hz. by Chris Lemm

It's very important to know that this switch doesn't act as the monitor part of a KVM switch. The KVM switch simulates the presence of a monitor for devices that are not actually displayed, so they don't know the monitor isn't there. It's more like unplugging the monitor and plugging it into another device - the computer going offline registers a disconnect event and the desktop is reconfigured. I have a PC with a GTX 1660 Ti with 3 DP monitors and a Mac Mini which I usually use via TeamViewer. But sometimes I need to see the Mac start up, or I want to use it directly with its own keyboard and mouse, so I used this to switch between PC and Mac on one of the monitors (Dell 27 inch with only one DP port). when i turned on a mac the pc registered a shutdown event and reconfigured the desktop without the 3rd monitor and all the windows on the 3rd monitor moved to the other 2 it thought it was headless and gave a resolution of 1280x 1024 out. If they could make a version of this thing that works like a KVM and spoofs the EDID for each device that would be perfect as true high resolution DP KVMs are very expensive. I ended up buying a mini DP to dual link DVI adapter that will allow me to use a different high resolution input on the monitor and I will be switching the display from PC to Mac that way.
