Question about Samsung S65UA
My Lenovo laptop has a USB-C port. Can I connect my laptop and this Samsung screen with a USB-C cable (USB-C connector on both sides) to transfer power and data so that only the Samsung screen then needs to be plugged into a power socket because the screen then also directly supplies the power for the laptop?
Yes you can, however I would not recommend this model as it is wider than a 32 inch 4K screen with much higher resolution of 3840x2160 pixels.
This monitor does it better and costs no more, it has Thunderbolt 3 interfaces and even a LAN connection, charging a notebook is also possible with it:
