All-in-one PCs are a great middle ground for those seeking a great home computer — they take up less room than traditional towers, and offer more screen space than most laptops. These unique PCs pack their components, ports and monitors into a single unit, allowing you to easily prop one onto your desk, plug in and get to work (or play).

How We Test All-in-One PCs

Every all-in-one we review goes through a variety of benchmark tests in Purch Labs as well as long hours of real-world use. As with our laptop reviews, we use a colorimeter to measure the brightness, color accuracy and color gamut of each all-in-one's display.

For performance, we use the Geekbench 4 test to measure a system's overall processing abilities. We also run a custom spreadsheet test to see how long a PC takes to match 20,000 names to addresses. To evaluate each system's hard drive speed, we measure how long it takes to copy 4.97 worth of files.

If an all-in-one has discrete graphics, we run it through many of the same benchmarks we use for gaming PCs. That includes 3DMark Fire Strike, as well as the built-in benchmark tools of games like Rise of the Tomb Raider, Hitman and Grand Theft Auto V. If an all-in-one is made to support virtual reality, we'll also run the SteamVR Performance Test.

Most importantly, we spend a ton of time simply using each all-in-one PC for everyday activities. We watch movies, do work, play games, and blast music on the speakers, all to get a better sense of which ones are worth your money.

    Stay away from the Zenbook Pro UX501VW 4K, MSI GS63VR Stealth Pro4K, and Inspiron 15 4K, in this list.

    The Zenbook Pro UX501VW, MSI GS63VR Stealth Pro, and Inspiron 15 4K all use the RG/BW Pentile matrix to cheat the ability to advertise as 4K.

    The screens are way wore than the TRUE 4K displays available in the Dell XPS 15, Lenovo IdeaPad 700 4K, Lenovo Yoga 910 4K, Dell Precision 4K, Lenovo Thinkpad P50 4K, and aren't even as good as the 15.6" 3K screens in the Thinkpad T560 and Aorus X5.

    The article is wrong, slightly. The $899.99 for the iMac at Best Buy is for the 21.5". You are stating you are getting the 27" for $899.99 and that is not accurate.
