What we like about this LG UltraGear 27GX700A-B monitor
Primary RGB Tandem OLED panel
The LG UltraGear 27GX700A-B uses LG’s newer Primary RGB Tandem OLED technology, bringing self-emissive pixel control to a 26.5-inch viewable QHD gaming display. OLED allows individual pixels to generate their own light and switch off for black, while the newer panel architecture is designed to improve brightness compared with earlier UltraGear OLED generations.
Up to 1,500 nits peak brightness
LG rates the monitor for peak brightness of up to 1,500 nits under the applicable measurement conditions. This is a peak highlight figure rather than full-screen sustained brightness, but it gives the panel substantially more luminance headroom for small HDR highlights while LG’s revised APL and ABL behavior is intended to improve brightness across larger image areas.
VESA DisplayHDR True Black 500
VESA DisplayHDR True Black 500 certification complements the panel’s increased brightness with OLED’s extremely low black level. Rather than relying on local-dimming zones, individual OLED pixels can shut down independently, allowing bright highlights to appear immediately beside black pixels without conventional LCD backlight blooming.
280Hz refresh rate
The native 2560 x 1440 panel can operate at up to 280Hz with an appropriate graphics card and connection. At maximum refresh, a new display cycle begins approximately every 3.57ms, making the 27GX700A-B particularly well suited to high-frame-rate competitive gaming.
0.03ms GtG response time
LG specifies a 0.03ms grey-to-grey response time, complementing the high refresh rate with extremely fast pixel transitions. OLED’s rapid response helps prevent slow pixel transitions from becoming a major source of motion smearing when displaying hundreds of frames per second.
99.5% DCI-P3 color
Up to 99.5% DCI-P3 coverage gives the monitor considerably broader color capabilities than a basic esports display. LG also cites UL verification for Perfect Black, Perfect Color with 100% Color Fidelity, and Perfect Reproduction, broadening its appeal for visually demanding games and media alongside pure competitive use.
FreeSync Premium Pro and G-Sync compatibility
AMD FreeSync Premium Pro and NVIDIA G-Sync compatibility allow the refresh cycle to follow compatible GPU output as frame rates fluctuate. This can reduce tearing and uneven frame presentation without requiring the graphics card to maintain precisely 280 FPS continuously.
HDMI 2.1 connectivity
Two HDMI connections are provided, with HDMI 2.1 explicitly supported, alongside DisplayPort connectivity. This makes the monitor suitable for a mixed PC and console setup rather than limiting its high-performance features to a single type of source.
Who should buy this OLED gaming monitor deal?
The LG UltraGear 27GX700A-B is primarily aimed at gamers who want the motion performance of a high-refresh esports monitor without sacrificing the black levels, HDR contrast, and color reproduction associated with OLED. Its 2560 x 1440 resolution is particularly sensible at this screen size because it offers substantially greater detail than Full HD without imposing the same rendering workload as 4K. Competitive players can make direct use of the 280Hz refresh rate and extremely fast OLED response characteristics. Shooters, racing titles, fighting games, and other rapidly moving games stand to benefit most when the PC can consistently generate high frame rates.
It also makes sense for users who divide their time between gaming and visual work. The combination of 99.5% DCI-P3 coverage, HDR support, strong black reproduction, and LG’s cited color verification gives it much broader image-quality credentials than a monitor designed solely around maximum refresh rate.
As with any OLED desktop monitor, long-term static content remains a consideration. OLED protection measures can reduce the risk of uneven pixel aging, but they do not change the underlying self-emissive nature of the panel.
