Hold on to your hats, gamers! Prepare for a monitor that might just redefine "fast." The LG 27GX790B is here, and it's not just another high-refresh-rate display; it's a potential game-changer, boasting a blistering 540Hz refresh rate and an even more mind-blowing 720Hz dual-mode. This could be the smoothest, most responsive OLED gaming experience ever. But is it all just hype? Let's dive in.
Following closely on the heels of the ViewSonic XG273F-2K-OLED, the LG 27GX790B enters the arena as part of LG's esteemed UltraGear lineup. What makes it special? It all starts with its 27-inch panel, built around LG Display’s cutting-edge 4th-Gen WOLED technology. This isn't your grandpa's OLED; it incorporates a new 4-stack ‘Primary RGB Tandem’ panel structure, designed to deliver enhanced brightness, color accuracy, and overall picture quality. Think richer colors, deeper blacks, and a more immersive gaming experience. On top of that, you get a crisp 1440p resolution, striking a sweet spot between detail and performance.
Now, here's where it gets controversial... That 540Hz refresh rate is impressive, no doubt. But LG takes it a step further with a dual-mode function. Engage this mode, and the monitor cranks the refresh rate all the way up to a staggering 720Hz! Yes, you read that right. The catch? You have to drop the resolution to 720p (HD). Is the trade-off worth it? That depends on your priorities and the games you play. Competitive gamers who prioritize every millisecond of response time might find the 720Hz mode invaluable, while others may prefer the higher resolution for a more visually stunning experience. It's a choice, and choices are good!
Let's break down the LG 27GX790B's specifications:
- Panel Size: 27 inches (technically 26.5 inches).
- Panel Type: WOLED (4th Generation).
- Curvature: Flat.
- Resolution: 2560 x 1440 (1440p).
- Pixel Density: 110 PPI (Pixels Per Inch).
- Response Time: 0.02ms G2G (Gray to Gray).
- Contrast Ratio: 1.5 million:1.
- Brightness (SDR): 335 nits.
- Viewing Angles: 178/178 degrees.
- Color Gamut: 99.5% DCI-P3.
These specs translate to a monitor that should be incredibly fast, responsive, and visually impressive. The wide color gamut ensures vibrant and accurate colors, while the near-instantaneous response time minimizes ghosting and blurring, providing a competitive edge in fast-paced games.
And this is the part most people miss... It's not just about raw speed. The LG 27GX790B also boasts adaptive-sync technology, supporting variable refresh rates (VRR) from both NVIDIA and AMD systems. This means you can say goodbye to screen tearing and stuttering, even when your frame rates fluctuate. The monitor has been certified under NVIDIA's 'G-sync Compatible' and AMD's 'FreeSync Premium Pro' schemes, guaranteeing a smooth and seamless gaming experience, regardless of your graphics card.
A Word of Caution: Pay close attention to the dual-mode resolution. The LG product page contains a slight inconsistency, listing it as both 1920 x 1080 @ 720Hz and HD @ 720Hz. The correct resolution is HD @ 720Hz, which translates to 1280 x 720.
LG has packed in other gaming-centric features, including Black Stabilizer (to improve visibility in dark scenes), Crosshairs (on-screen aiming aids), and an FPS Counter. The monitor is also VESA ClearMR 21000 certified, indicating excellent motion clarity performance. However, there's no mention of Black Frame Insertion (BFI), a technology that can further reduce motion blur, but at the cost of brightness.
For HDR enthusiasts, the LG 27GX790B is certified under the VESA DisplayHDR True Black 500 tier. Thanks to its 4th Gen WOLED panel, it can reach a peak brightness of 1500 nits (at 1.5% APL - Average Picture Level). It also offers 800 nits at 10% APL and 335 nits at 100% APL. These numbers suggest a capable HDR performance with bright highlights and deep blacks, creating a more dynamic and realistic image.
Beyond gaming, the LG 27GX790B offers the LG Switch smart function, which transforms your screen into a hub for work, gaming, and streaming. It allows you to customize image quality and brightness settings and apply them with a hotkey depending on the task at hand. The stand offers tilt, height, swivel, and rotate adjustments for optimal ergonomics, and the hexagonal backlighting adds a touch of style. LG also includes various OLED Care features to prevent image retention and burn-in, backed by a 3-year warranty for peace of mind.
One key difference between this LG model and some of its competitors, like the Asus ROG Swift PG27AQWP and the ViewSonic XG273F-2K-OLED, is the panel coating. The LG 27GX790B uses a standard matte anti-glare coating, while the Asus and ViewSonic models seemingly opt for a glossy finish. The matte coating excels in brighter environments, minimizing glare and reflections. However, glossy coatings often provide a more vibrant and contrast-rich image in controlled lighting conditions. Which is better? It's a matter of personal preference and your typical usage environment.
Connectivity options are plentiful, including 2x HDMI 2.1 ports, 1x DisplayPort 2.1 input (UHBR tier unspecified), a 4-pole sound and mic jack, 2x USB 3.0 Type-A connections, and 1x USB 3.2 Type-C connection (with DP Alt Mode). The monitor also supports PiP/PbP (Picture-in-Picture/Picture-by-Picture) for multitasking with multiple devices.
Availability and Pricing: The LG 27GX790B has initially launched in China. Hopefully, we'll see it released worldwide soon, perhaps with a grand unveiling at CES in January.
So, what do you think? Is 720Hz overkill, or the next evolution in gaming displays? Is the trade-off in resolution worth the extra speed? And which panel coating do you prefer: matte or glossy? Share your thoughts in the comments below!
