Is the ZBook Studio G4 good for CAD and 3D work?

Yes, for moderate projects. The quad-core Core i7 and dedicated graphics run CAD and 3D apps well, and HP certifies the machine for major ISV applications. Very large assemblies will want more than 8 GB of RAM.

Can I upgrade the RAM and storage?

Yes. The memory is DDR4 SO-DIMM and can be expanded beyond the base 8 GB, and the M.2 SSD can be swapped for a larger drive. Check the service manual for the exact supported capacities.

How does it compare with a standard 15.6-inch laptop?

It is thicker and heavier than a consumer ultrabook but lighter than most mobile workstations. You get ISV certification, a matte IPS screen and stronger graphics, at the cost of battery life and portability.

Does it have USB-C and HDMI?

Yes. It has two USB-C ports, HDMI and USB-A, plus a headphone jack. That covers modern docks and legacy peripherals without an adapter for most setups.

Is the screen good for photo and video editing?

The matte Full HD IPS panel offers stable colors and wide viewing angles, which suits editing. For color-critical print work, check the specific panel's color gamut before buying.

What comes in the box?

Typically the laptop, a power adapter and power cord, and setup documentation. A stylus, dock or carrying case is not included unless a specific bundle lists it.
