Hello

I have Samsung Odyssey G7 32'' and I have connected cable usb-b (printer connector on monitor?) to usb-c but it does nothing ? only shows that display connection might be limited, when I connect smartphone it doesn't charge. So what is usb-b 3.0 or is it 3.1 or 3.2 ? What is is for ?  The USB-A both charging phones.. 

Thanks

 I didn't know, in menu says fast charging so thought it support it but usb-a ports do charge phone but slow basic charge only ..

You can activate fast charge via settings 👌

Hi I know but it doesn't work for smartphones so again another useless thing it is just normal 5V 1A or maybe 2A  power  .. So it is only for keyboard and mouse charge basically
