Ranked #3 in Best 1440p 144hz Gaming Monitors

AOC Q27G3XMN

4.4

3 sources1 derived$229.99as of Aug 1

The AOC Q27G3XMN is a 27-inch 1440p VA gaming panel built around a 336-zone mini LED backlight, which is what gets it a DisplayHDR 1000 badge at a price where HDR is normally a sticker rather than a capability. TFTCentral's read is that the feature set is unusually aggressive for the money. It runs at 180Hz with FreeSync Premium Pro over a native 4,000:1 contrast ratio. The compromises are real: sRGB content oversaturates unless the emulation mode is on, local dimming blooms around small bright objects, and there is no HDMI 2.1 or USB-C.

Strengths

— 336-zone mini LED FALD backlight for excellent HDR performance
— VESA DisplayHDR 1000 certification with 1300-nits peak brightness
— 180Hz refresh rate with AMD FreeSync Premium Pro support

Watch-outs

— sRGB emulation mode needed for accurate sRGB SDR content
— Potential blooming/halo effect from FALD local dimming

Dell Alienware AW2725DF

4.6

5 sources$650as of Aug 1

The Dell Alienware AW2725DF runs a Samsung Display QD-OLED panel at 360Hz, which puts it among the fastest OLED monitors tested. Tom's Hardware praised the high refresh rate and adaptive-sync support, and TFTCentral noted the panel's rated 0.03ms G2G response time and fully adjustable stand. Reviewers also pointed out that the screen wobbles during adjustments and that the cooling fan is audible. Hardcore gamers chasing ultra-high refresh rates are the fit; anyone who wants a rock-steady stand or silent operation is not.

Strengths

— 360Hz refresh rate with adaptive-sync support including AMD FreeSync Premium Pro and VESA AdaptiveSync
— Samsung Display QD-OLED panel with 2560 x 1440 resolution and 1000 nits peak brightness
— 0.03ms G2G response time for gaming

Watch-outs

— Screen has noticeable wobble during adjustments
— Active cooling fan audible when listening closely

How they stack up

AOC Q27G3XMN

Mini LED backlights at this size normally cost considerably more, and the trade the Q27G3XMN makes to get there is zone count: 336 against the 576 or more that pricier full-array displays use, which is the direct cause of the blooming. Against a standard edge-lit VA panel at the same price it is a straightforward upgrade in contrast and peak brightness; against an OLED it wins on brightness and loses on microcontrast, viewing angles and VRR behaviour.
