I've got dp cable and ports on monitors and 3 on pc. Can't get dp ports working or the second hdmi pc port at the top separate from the others.
Turns out while we were out walking the dog or son found a setting in w11 and selected something. When we got home it still didn't work until my oartner pulled one dp out of the pc then plugged it back in. It suddenly came on. He showed us the setting it was where you switch which monitor is left or right side.
I must admit w11 to me has a difference to it over w10 I'm used to. Might take some getting used to it when work changes our laptops over to it. Might be later this year or 2025 but I'll have to play around with it when we do get it. Don't like being the guy who has to go to his son to fix something!
