Also have a single 4K 28" Can confirm that is has to be DisplayPort "Oh cool, 4K@60Hz KVMs aren't expensive anymore," I thought. And then about 120 dollars in cables and adapters later, I can even get the 4K@60Hz signal to the monitor! Never had that issue with DP before. Never had it negotiate to a spec it couldn't transmit. Never had it drop out 30s in. HDMI is a mess.
