The Quality is worth the price.
Quality and worth it. Use it in a business, very harsh conditions for a computer, and this one does the job. I did upgrade the keyboard and mouse to wireless. The touchscreen is great, and the display is clear. The power and sleek design is spot on.

1. Does the USB-C Display port on the 840 AIO support "Alternate Mode"? If so, do I understand correctly there should not be any issues connecting a HP monitor with a USB-C connection to the 840 AIO using the USB-C to USB-C provided cable .
