Questions about HP Envy x360 15

That's right, it's a 4k AMOLED display, not FHD as in the text. It has a Type C 10 GBit/s port with power delivery. Source is the datasheet from HP: https://www8.hp.com/h20195/v2/GetPDF.aspx/c06656133.pdf

Can I also charge the device via USB-C? How many watts do I need for this (45 watts or 65 watts)?

Hello, We would need the device for the vocational school, intended use also for CAD programmes. Therefore, the graphics card is important (would be better separately), how much can the processor take over (so in approx. GB data) Thanks in advance.

The description does not quite match the specification yet. Regarding the resolution ; ) And is there really no Thunderbolt 3 on this model, as there is on the other new Envy models? Thanks in advance for an answer.
