Curated comparison
These displays target different size and resolution choices: a compact 23.8-inch 1080p panel and a 27-inch 1440p panel. This comparison uses their manufacturer-listed specifications, checked on 9 September 2026, and transparent pixel-density calculations. It is not a hands-on image-quality or response-time test.
Requirements first
Compare known specifications and compromises. Personalised Fit Scores appear only when you have supplied requirements.
Bottom line
Choose the AOC for a smaller screen and a lower pixel workload at native resolution. Choose the ASUS for more desktop workspace and finer pixel density, provided your desk and graphics output suit 1440p. Both advertise up to 180 Hz, so the maximum refresh number alone does not decide this comparison; supported modes depend on the input and connected computer.
A compact 1080p setup, where physical screen size and native-resolution graphics workload matter more than extra desktop pixels. Its approximately 93 PPI is lower than the ASUS; fine text will not have the same density.
A 27-inch 1440p workspace with approximately 109 PPI, about 17% greater density than the AOC. It renders about 78% more pixels per frame; that is a workload comparison, not a predicted frame-rate penalty.
Lowest planning cost: AOC 24G4XE Gaming Monitor at £120. This is a catalogue estimate, not a current offer or a claim of best value. No performance or overall winner is awarded without comparable evidence.

The ASUS has 2560 × 1440 pixels, compared with 1920 × 1080 on the AOC. That gives more potential workspace at the same scaling percentage, while its larger diagonal offsets some of the difference in text size. Compare readable scaling in the applications you use.
ASUS lists up to 180 Hz through DisplayPort and a vertical HDMI range up to 144 Hz. Do not assume that an advertised maximum is available through every port, dock or console. Check the AOC input timing table and the output modes of your own device as well.
ASUS documents a 61.5 cm casing width, 21.4 cm stand depth, 3.6 kg weight without stand and 100 × 100 mm VESA mounting. Use those numbers for desk and arm checks. The AOC mounting and weight fields are not yet verified in this comparison; missing values are not treated as a compatibility pass.
Neither refresh rate nor an IPS label proves better motion handling, calibrated colour or panel uniformity. This page does not award a tested performance winner. For creative work, research gamut, calibration and the specific panel revision before choosing.

Common questions
Using the manufacturers’ diagonal and resolution figures, the AOC is about 93 PPI and the ASUS about 109 PPI. The ASUS has higher pixel density, but viewing distance, scaling and text rendering affect the visible result.
1440p contains about 78% more pixels than 1080p. Actual frame rate depends on the game, graphics settings, GPU and CPU, so pixel count cannot predict a fixed performance penalty.
