Not sure if this is a support question as I haven’t actually ordered yet but is this combination going to work? And if so, will USB from the Pi itself be enough to power the screen so I don’t need two wall plugs?
Just wondering if I need a ribbon cable like you do with the 7" but I couldn’t find anyone even asking this question so wanted to check first.
From HDMI side, there should be no problem. USB3 has a power limit of 900mA, which is slightly below the 1A of the 10"-display. The Pi5 has a budget-limit of 1.6A for USB, but I don’t know if they enforce the 900mA of the standard or not. And the limits in the datasheet are not always limits that are actually used.
