I have a 7th gen i7 U processor in my transformer pro 3 and the Y processor in the V beats it handily.
Here, let me fix this for you:
Nothing. Nothing at all for the next 5 or 6 years at least. You’ll actually be better off with a HDMI port. Which - surprisingly - is a pain in the ass to find on 2-in-1s.
I think for most people the ideal port selection would be 1xUSB-C (for charging as well) , 2xUSB-A and 1xHDMI.
The USB-C port could also be TB3 but that would add cost that I think most people won’t make use of.
