Our take on the HP 21.5" All-in-One

The HP 22-dg0034 is a 21.5-inch all-in-one desktop built around Intel's low-power N100 quad-core processor, 8GB of DDR5 memory and 128GB of UFS storage. The 1920x1080 VA panel is anti-glare and non-touch, and the machine runs Windows 11 Home in S Mode. It suits light everyday work: browsing, email, documents, video calls and streaming. Against rivals it trades speed for quiet, low-power operation, and the small UFS storage and single memory slot limit how far it can grow.

Questions and answers

Is the HP 22-dg0034 good for everyday home use?
Yes. It handles browsing, email, documents, video calls and streaming comfortably. It is not built for gaming or heavy editing.
Can I upgrade the memory or storage?
There is one memory slot, already filled with 8GB DDR5, so upgrading means replacing that module. Storage is 128GB UFS, which is not a standard user-swappable drive.
Does it have a touchscreen?
No. The 21.45-inch VA panel is non-touch and has an anti-glare finish.
What is Windows 11 S Mode?
S Mode limits you to apps from the Microsoft Store for security and speed. You can switch it off once to install other Windows apps.
What ports does it have?
Two USB-A 2.0, two USB-A 3.0, one USB-C 3.1, HDMI out, Ethernet, a microphone input and a headphone jack, plus Wi-Fi 6 and Bluetooth.
Is it good for gaming?
No. Intel UHD Graphics and the N100 processor suit light tasks only, not modern games.
