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 .

    Asked by: moolachaser
    Thank you for your question about the HP EliteOne 840 G9 All-in-One PC Wolf Pro Security Edition (A27JLUA). Yes, it will be able to work with the provided USB-C cable that comes with the HP Series 5 Pro 23.8 inch FHD USB-C Monitor - 524pu (9D9V7AA). You will want to make sure you use the correct USB-C port on the rear of the 840 G9 (A27JLUA) that has DisplayPort Alt support.
