ASUS ROG Strix XG27ACS vs AOC Q27G3XMN
Which should you buy? Our verdict on both, pulled from our full Best Budget 1440p Gaming Monitors (27"): What's Actually Worth It comparison.
For most people the ASUS ROG Strix XG27ACS is the safest buy: fast IPS motion, accurate color, USB-C and a fully adjustable stand at a fair price. If you game mostly single-player and want HDR that actually impresses, the AOC Q27G3XMN's mini-LED backlight is the standout value. Choose the LG 27GP850-B only when it's on sale and color accuracy matters most. We'd skip the Samsung Odyssey G5 - it's a recognizable name asking similar money for weaker motion, a barebones stand and HDR in name only.
ASUS ROG Strix XG27ACS
Buy itThe best all-rounder here: fast IPS, accurate color out of the box, and a proper adjustable stand.
- Fast IPS with 180Hz and near-instant response - clean, tear-free motion
- Reviewers found it accurate out of the box, with 97% DCI-P3 coverage on ASUS's spec sheet
- Full ergonomic stand plus USB-C video input
- HDR is entry-level (400 nits, no local dimming) - fine, not exciting
- 1000:1 contrast means blacks look grey in a dark room
AOC Q27G3XMN
Buy itThe cheapest way to get HDR that actually does something, thanks to a 336-zone mini-LED backlight.
- Real HDR: 336-zone mini-LED local dimming with VESA DisplayHDR 1000 certification
- High-contrast VA panel (4000:1 static) with wide color coverage (101% DCI-P3 on AOC's sheet)
- 180Hz and real HDR at a price others can't match
- VA panel shows mild dark smearing in fast, shadowy scenes
- Visible blooming around bright objects on dark backgrounds
- Local dimming can be fiddly outside of HDR content
