The Sharpest 27-Inch Monitors Under $400
Twenty-seven inches is where the resolution argument actually happens, because both 1440p and 4K are sold at that size for under $400 and the marketing gives you no way to tell what the difference looks like. Pixels per inch does not settle it either — it cannot be compared between a 27-inch and a 32-inch screen, since nobody sits the same distance from both. Pixels per degree can: it is how much resolution lands on your retina from where you actually sit, and 60 is the point where 20/20 vision stops resolving the grid.
How this list is ordered: Ranked on pixels per degree of vision at a 24-inch viewing distance, then by price where two are level. 11 of the catalog’s monitors qualify.
1Dell

3Lenovo
~$200Lenovo Legion R27qe
Two hundred dollars, 180 Hz at 1440p, and a stand that lifts 120 mm and rotates into portrait — that combination is the entire argument for this monitor.

4ASUS
~$209ASUS TUF Gaming VG27AQ3A
The spec worth knowing about here is not the 180 Hz — it is ELMB Sync, which runs backlight strobing and adaptive sync at the same time.

6MSI
~$250MSI MAG 274QRF QD E2
Quantum-dot film over a Fast IPS panel is what gets 98% of DCI-P3 out of a $250 monitor, and a KVM at that price is close to unheard of.

7AOC
~$270AOC Gaming Q27G3XMN
Local dimming starts here: nothing else in this catalog costs less and still has a backlight that dims in sections.

8Acer
~$300Acer Nitro XV272U V3
Three hundred dollars is the whole story here, and Acer spent it on the two things people notice: 1440p at 180 Hz, and 95% DCI-P3 coverage on a panel rated at 0.5 ms grey-to-grey.

9BenQ
~$300BenQ GW2790QT
White, quiet and built around one USB-C cable, this is a video-call monitor before it is anything else: the microphone has noise cancellation, the speakers have a noise filter, and an ambient sensor trims brightness as the room changes.

11Acer
~$350Acer Predator XB273U V3
Predator is Acer's gaming brand rather than a specification, and on this model the difference from the cheaper Nitro amounts to 50 more nits, a red-accented chassis and G-Sync Compatible certification on top of FreeSync Premium; the panel underneath is the same class of 27-inch 1440p IPS at 180 Hz with 0.5 ms rated response.
