| The upcoming LG 32GX870B will be LG's first 4K monitor with its Tandem OLED panel. |
The buzz at CES 2026 just reached a new pitch. LG, already making waves with its new lineup of UltraGear evo 5K displays, has dropped another bombshell for performance-hungry gamers and creators. The company is officially expanding its revolutionary Tandem OLED technology into the 4K arena with the brand new UltraGear evo 32GX870B—and it’s poised to redefine what we expect from a high-end gaming monitor.
This isn't just another spec bump. The 32GX870B is the very first 4K gaming monitor built around LG’s cutting-edge 4th-Gen Primary RGB Tandem OLED panel. For those catching up, this "four-stack" structure debuted last year in 1440p models, offering unparalleled brightness and longevity compared to traditional OLEDs. Now, that same robust technology is powering a 4K dream machine.
Sharpness Meets Speed: The Core Specs
While LG is holding some details close to its chest until the full CES reveal, the confirmed specs are enough to get any tech enthusiast's heart racing.
- The Perfect Pixel Density? The monitor features a 32-inch 4K (3840 x 2160) panel. This combination hits a sweet spot, delivering about 138 pixels per inch (PPI). For perspective, that’s significantly sharper than the ~109 PPI of a popular 27-inch 1440p monitor. Text will be crisper, and in-game details will pop with stunning clarity.
- The Tandem OLED Advantage: You can expect the exceptional contrast, perfect blacks, and lightning-fast response times OLED is famous for, but with the enhanced brightness and durability that the Tandem structure provides. LG confirms 99.5% DCI-P3 coverage and VESA DisplayHDR True Black 500 certification, guaranteeing breathtaking color and HDR performance.
- Refresh Rate Royalty: Here’s where it gets wild for competitive gamers. The 32GX870B natively runs at 4K 240Hz, offering buttery-smooth gameplay at the highest resolution. But for esports titles where frames are king, it can dynamically switch to a blistering 480Hz refresh rate at 1080p. This flexibility is a game-changer.
Built for the Future
LG understands that not all content is native 4K. To bridge the gap, the monitor will feature AI-powered upscaling, designed to sharpen lower-resolution game streams and videos, making them look closer to true 4K.
Connectivity is thoroughly modern, ready for next-gen GPUs and consoles. The monitor is listed with DisplayPort 2.1 and HDMI 2.1 ports, ensuring support for high-bandwidth signals. For laptop users, a USB-C port with 90W Power Delivery offers single-cable connectivity for both video and charging.

Where Does It Fit in the Market?
The introduction of a 4K Tandem OLED panel is a major milestone. Until now, enthusiasts had to choose between the speed and clarity of Tandem tech at 1440p (like in the impressive Gigabyte MO27Q28G) or opt for a different 4K OLED technology. The 32GX870B aims to end that compromise, offering the pinnacle of both resolution and panel performance in one package.
The Big Questions Remain
As with most CES announcements, the crucial details of price and exact availability are still under wraps. Given the premium technology, expect the UltraGear evo 32GX870B to command a premium price tag, likely positioning it as a flagship product for 2026.
One thing is clear: LG is not just iterating; it's innovating. By bringing its most advanced OLED technology to the coveted 32-inch 4K format, the 32GX870B isn't just a new monitor—it's a statement. We'll be watching closely for hands-on impressions from the CES show floor.
