HP Envy X360 Laptop 13"HD Touch I7 16GB Silver

Is this compatible with the HP Pen? Model number?

Yes, it is HP pen compatible.

What about the model number?

The laptop? 5130664

is this the 4k version?

I’m also curious if this is the 4k version and the model number.

The 4k version is 3840 x 2160 and this one says its 3200 x 1800 so maybe not?

This one is QHD+ which is not quite the same as 4K.

Model number: 13-Y034CL
