Hi Chris, I received a U2417h monitor as a replacement for the faulty U2414h, the first day seems ok.  But in the 2nd day when I turn on the computer from monitor's power saving mode the monitor wouldn't detect my hdmi cable, I had to turn off the monitor, unplug and re-plug the cable, turn monitor back on and then it would work but then it would randomly go into black screen with the hdmi cable not detected floating box again and I had to redo everything again.  I don't think it's my hdmi cable's problem since I've used it for the previous monitor without any issues.  It's getting way too frequent and it's really annoying.  I'm trying to turn off auto detect input source from osd menu, see how it goes.
