It worked fine two minutes ago. I can still get image via Analog. HDMI cable works fine. PC works fine with same cable, another monitor. Monitor works fine with another PC. I tried the problem PC-monitor combination with a second HDMI cable, doesn't work either. All items works fine with other equipment except this setting.
Is there any reason why that particular PC does not work with that particular monitor through that particular port? Except maybe the fact that they had a fight that I'm not aware of?
