LG UltraGear OLED 27GX700A-B 27" WOLED Gaming Monitor
280Hz · 0.03ms4th Gen WOLED QHD1500 nits · True Black 500G-Sync + FreeSync Pro
The LG UltraGear OLED 27GX700A-B, part number 27GX700A-B.AEU, is a 27-inch (26.5-inch viewable) WOLED gaming monitor with QHD 2560 x 1440 resolution and a 280Hz refresh rate, built for competitive gamers and streamers who also want HDR brightness. It is LG's first display to use the 4th-generation Primary RGB Tandem WOLED panel, reaching up to 1500 nits peak brightness with VESA DisplayHDR True Black 500 certification, a 1,500,000:1 contrast, 99.5% DCI-P3 coverage and a 0.03ms (GtG) response, all behind a matte anti-glare coating. Typically in stock with fast delivery across Cyprus.
Good to know: The full 280Hz needs a DisplayPort 1.4 or HDMI 2.1 connection from a compatible graphics card; PS5 / Xbox Series X run at up to 1440p 120Hz over HDMI 2.1. As an OLED, leave the built-in panel-protection routines enabled to guard against burn-in. The matte coating favours bright rooms over the glossy look of QD-OLED rivals.

Frequently Asked Questions
Does the 27GX700A-B work with a PlayStation 5 or Xbox Series X?
Yes. The HDMI 2.1 inputs support QHD gaming at up to 120Hz from a PS5 or Xbox Series X. To reach the full 280Hz you need a PC connected over DisplayPort 1.4 or HDMI 2.1 with a compatible graphics card.
Is the 27GX700A-B bright enough for a well-lit room?
It is one of the brightest OLED gaming monitors available, reaching up to 1500 nits peak with DisplayHDR True Black 500. Its matte anti-glare coating also reduces reflections, making it more usable in bright rooms than glossy QD-OLED alternatives.
What is the difference between the 27GX700A and the 27GX790A?
Both are 27-inch QHD UltraGear OLEDs, but the 27GX700A runs at 280Hz over DisplayPort 1.4 / HDMI 2.1, while the 27GX790A pushes 480Hz using DisplayPort 2.1 (UHBR20). Choose the 27GX700A for high-refresh QHD with peak brightness; pick the 27GX790A only if you need 480Hz.
What should I know before buying the 27GX700A-B?
It uses a WOLED panel, so keep the built-in OLED care features enabled to protect against burn-in. The matte coating suits bright rooms, the stand offers height, tilt, swivel and pivot, and it is VESA wall-mount compatible. Use DisplayPort 1.4 or HDMI 2.1 for the full 280Hz.
Singular Expert Insight
The 27GX700A-B is the brightness specialist of the QHD OLED class: its 4th-gen WOLED hits up to 1500 nits and carries DisplayHDR True Black 500, a step above the True Black 400 rating of most QD-OLED rivals, and the matte coating makes it the easy pick for brighter rooms. If you want maximum HDR brightness and glare control, choose this. If you prefer glossy QD-OLED colour saturation and a slightly higher 360Hz refresh, the ASUS ROG Strix XG27AQDNG is the alternative; for raw speed, LG's own 480Hz 27GX790A is the step up.
Buyer's Guide
Buy it if
You want the brightest QHD OLED (up to 1500 nits, True Black 500), game in a well-lit room, and value 280Hz with 0.03ms and a full ergonomic stand.
Skip it if
You need 4K resolution, prefer glossy QD-OLED colour pop, or want 360-480Hz for pure esports - consider a UHD OLED or the 480Hz 27GX790A instead.
Also consider
The 480Hz LG 27GX790A (DP 2.1), the 360Hz ASUS ROG Strix XG27AQDNG (glossy QD-OLED), or a 4K OLED for desktop detail.
