It seems someone already tried that. And this one does have EDID.
Time to waste my wallet again. TBH, it’s way cheaper than the L1KVM I just bought (and the accessories). Pleb tier HDMI and USB Type B 2.0 are dirt cheap. On the L1 KVM, had to look for short length DP, to ensure signal integrity (because the L1 store didn’t have them in stock, RIP) and I needed USB Type B 3.0 (I probably could’ve gotten away with just usb 2 cables, given I only have a kb and 2 mice attached).
Anyway, having remote, non-rooted Android devices that I can control from afar without installing spyware on my main device is what I’m looking for. I think I cracked the code.
