All-in-One Desktop Computers

Screen size and stand: you are buying the monitor too

An all-in-one hides the computer behind the screen, so the display choice is permanent. A 24 inch panel suits a desk or counter, while 27 inches suits shared or design work. Read the resolution, panel type and refresh rate in the title, such as 1080p IPS at 100 Hz, and whether it has touch. Check the stand too: tilt only, or height adjustable. Built-in camera, speakers and microphone replace separate parts, but many all-in-ones cannot serve as a monitor for another computer, so look for an HDMI input if you want that.

Processor era, memory and what you can upgrade

Listings cover a decade of processors, from 3rd generation Core to 13th generation, so read the generation, not just i5. Windows 11 officially starts around 8th generation, and Windows 10 has passed its normal end of support, so check older machines for eligibility. Memory is DDR3, DDR4 or DDR5 and is not interchangeable; all-in-ones often use laptop-style modules, and some solder them. Choose an SSD for the system drive, since very small drives fill quickly with updates. Integrated graphics suit office work; a stronger GPU is named in the title.

Questions about All-in-One Desktop Computers

Can an all-in-one be used as a monitor?

Only if it has an HDMI or DisplayPort input, which many all-in-ones lack. Most have outputs only and work as standalone computers. If you want a second screen, look for an input port in the specifications.

Can I upgrade the memory or storage?

Sometimes. Many models have an access panel for memory or an M.2 slot for storage, but some solder the memory or need the case opened. Check the maximum supported memory and the module type before planning an upgrade.

Is 8 GB of memory enough?

For browsing, office apps and video calls on Windows 11, 8 GB works but leaves little headroom. 16 GB is the safer choice, especially if you keep many browser tabs open or run several applications at once.
