For 5 weeks, monitor worked great with USB-C input, also charging my laptop. Using the provided cables. Loved the minimal cables required. It stopped working. I'm now connected through HDMI.   

Also, won't charge laptop. When I plug it into my laptop, the laptop gives me a message that it may be slow and lower resolution. Regardless,  the S2722QC never recognizes an input.   

It will charge my phone for some reason?  

I've now updated the firmware. Also installed Dell Display Manager 2.1 on the Dell laptop I use. Running Windows 11, which I believe is what came standard on my Latitude 7430.   

How can I get it to work again?
