| The LG 27GX790B Tandem OLED monitor with 720 Hz dual mode is now available in the US for $999.99. |
For competitive gamers and display enthusiasts who thought OLED technology couldn't get any faster, LG has just raised the bar dramatically. The highly anticipated LG UltraGear 27GX790B-B, previously launched in China, has now officially landed in North America. This 27-inch QHD monitor isn't just another incremental update; it's a showcase of LG Display's latest 4th Gen Primary RGB Tandem OLED panel, pushing refresh rates to mind-bending new heights that challenge the very limits of current gaming monitors.
Priced at an aggressive $999.99 in the US, the UltraGear 27GX790B-B enters the high-end arena with a compelling proposition: unmatched speed meets next-generation OLED picture quality.
The Need for Speed: 540Hz Native, 720Hz at the Ready
The headline feature is, without a doubt, the monitor's staggering refresh rate. At its native 2560 x 1440p resolution, it operates at a fluid 540 Hz, instantly outclassing most QD-OLED and fast IPS competitors. But LG has included a secret weapon for esports purists: a dedicated 720 Hz mode that activates when the resolution is dropped to 720p.
This dual-mode approach caters directly to professional and aspiring competitive players in titles like *Counter-Strike 2*, Valorant, and Rainbow Six Siege, where every millisecond and frame of clarity counts. Combined with a near-instantaneous 0.02 ms GtG response time and support for both NVIDIA G-SYNC and AMD FreeSync Premium Pro, the monitor promises buttery-smooth, tear-free gameplay that feels almost telepathically connected to your inputs.

More Than Just Speed: The Tandem OLED Advantage
While the speed is groundbreaking, the shift to a Tandem OLED architecture brings substantial quality-of-life improvements over previous WOLED generations. The most notable upgrade is in brightness. The monitor boasts a peak HDR brightness of 1,500 nits, allowing for spectacular highlight detail. Even in Standard Dynamic Range (SDR) mode, it sustains a robust 335 nits, making it more usable in bright rooms than many earlier OLED panels that often struggled with ambient light.
Color performance also sees a bump, covering 99.5% of the DCI-P3 color gamut. When you pair this with OLED's perfect per-pixel dimming and infinite contrast, the visual experience for both gaming and content consumption is expected to be exceptional. LG also touts a ClearMR 21000 certification, a rating that indicates superior motion clarity by minimizing blur in fast-moving scenes.
Modern Connectivity and Availability
Recognizing the need for future-proofing, LG has equipped the 27GX790B-B with a DisplayPort 2.1 interface, ensuring ample bandwidth for its high refresh rates and resolutions. This is joined by USB-C connectivity and a fully adjustable stand for ergonomic comfort.
The monitor is available now in the United States through major retailers like Amazon. Canadian gamers can currently secure a pre-order for CA$1,299.99, with shipping estimated to begin on January 15, 2026.
The launch of the UltraGear 27GX790B-B marks a significant moment in the gaming monitor space. It successfully answers the demand for higher refresh rates without sacrificing the visual virtues of OLED technology, all at a price point that undercuts some spec-similar competitors. For the gamer seeking the ultimate combination of responsiveness and image fidelity, LG's new contender is now on the battlefield.
