TL;DR
LG is releasing a dual-mode GX7 OLED gaming monitor in the US that can operate at ultra-high refresh rates. The 26.5-inch 27GX790B uses LG Display’s fourth-generation WOLED panel and offers 540Hz at 1440p or 720Hz at 720p, with a mode toggle to switch between them.
What happened
LG has introduced a new dual-mode GX7 OLED gaming monitor for the US market, the 26.5-inch model designated 27GX790B, priced at $999.99. The display is built on LG Display’s fourth-generation WOLED panel and is presented as offering industry-leading speed and brightness. The monitor supports two distinct operating modes: a 1440p mode that runs at up to 540Hz, and a lower-resolution 720p mode that can reach up to 720Hz. The product includes a dual-mode option that allows users to switch between the 540Hz and 720Hz settings, though the source excerpt trails off before specifying exactly how that switching is performed. Beyond the model, panel generation, size, advertised brightness claim, price, and the two resolution/refresh-rate combinations, other details such as release timing, full specifications, port selection and real-world performance metrics are not confirmed in the source.
Why it matters
- Ultra-high refresh rates like 540Hz and 720Hz target competitive gamers seeking the smoothest possible motion and lowest input latency.
- Offering two refresh/resolution modes highlights a trade-off between pixel resolution and peak frame rate, letting users prioritize speed or image detail.
- Use of LG Display’s fourth-generation WOLED panel indicates continued development in OLED monitor technology from LG’s panel division.
- At a $999.99 price point, this monitor positions itself in the premium segment where buyers will weigh frame-rate benefits against resolution and other features.

Quick glossary
- OLED: Organic Light-Emitting Diode; a display technology where each pixel emits its own light, enabling deep blacks and high contrast.
- WOLED: A type of OLED panel that typically uses white OLED subpixels combined with color filters to produce full-color images; used by some manufacturers for high-quality displays.
- Refresh rate (Hz): The number of times per second a display updates the image, measured in hertz (Hz); higher rates can produce smoother motion.
- 1440p: A display resolution commonly called Quad HD (QHD), typically 2560×1440 pixels, offering higher detail than 1080p.
- 720p: A display resolution with 1280×720 pixels, lower than 1080p and 1440p but sometimes used to reach higher frame rates.
