Hi community,

I have Dell s2716dg monitor and two different Win 10 laptops (Lenovo Yoga 7 pro and HP EliteBook 745 G6), one day my external monitor just stopped being detected and no matter what I do it just won't detect, I tried all of the usual steps recommended. I'm using uni USB-C to DisplayPort Cable and it worked without issues for more than a year, now same issue is with both laptops and I tried with different Dell monitor and it was the same issue. I know cable and external monitor are fine, I connected my Samsung phone and it worked fine. Probably windows issue? I'm running out of options here, if anybody has ideas pls help.
Thanks!
