OLED or IPS? Choosing a 27-inch 1440p monitor

At 27 inches, 2560 × 1440 is the resolution most people settle on: sharp enough for work, light enough for a mid-range graphics card to drive in games. The real decision is the panel type — and, for OLED, the screen finish.

OLED or IPS, in plain terms

Glossy or matte?

A glossy finish makes colours and blacks look richer, but reflects lamps and windows. A matte/anti-glare finish tames reflections at the cost of a little clarity. If your desk faces a window, lean matte.

ASUS ROG Strix OLED XG27AQDMG

26.5-inch OLED · glossy

Resolution / refresh
2560 × 1440 · 240 Hz
Panel
26.5-inch WOLED, glossy
Warranty
3 years (ASUS)
Inputs
1 × DisplayPort 1.4, 2 × HDMI 2.0

Why: 240 Hz OLED with a glossy finish, for a darker room where reflections aren’t a problem. ASUS lists a 3-year warranty.

The catch: glossy means reflections. Its HDMI ports are 2.0; for high refresh rates from a PC, use DisplayPort.

Panel
26.5-inch OLED, anti-glare

2 years (LG)
Inputs
2 × HDMI, 1 × DisplayPort

Why: the same resolution and 240 Hz, with an anti-glare, low-reflection surface for bright rooms.

The catch: LG lists a 2-year warranty — a year less than the ASUS. For a burn-in-prone panel, check exactly what the warranty covers before buying.

Dell UltraSharp U2724D

Panel
27-inch IPS Black
Colour / contrast
100% sRGB, 98% DCI-P3 · 2000:1
Warranty
3 years (Dell)

Why: no burn-in worry with static windows, an anti-glare coating, wide colour coverage by Dell’s figures, and a 3-year warranty.

The catch: 120 Hz, not 240, and blacks won’t match an OLED. This is the office and photo-editing pick, not the gaming one.
