Pre-Orders Open for LG's 31.5-Inch 4K Tandem OLED Gaming Monitor 32GX870B-B!
The 32GX870B-B is a 31.5-inch gaming monitor with 4K resolution (3,840×2,160) that features the latest organic EL panel, Tandem OLED.
By evolving the light-emitting layer structure from the conventional three layers to four layers, it achieves both high brightness and improved color reproduction while maintaining the exceptional black reproduction unique to organic EL.
The brightness reaches 335 cd/m2 as a standard value, and 1,500 cd/m2 at APL 1.5%, covering 99.5% (standard value) of DCI-P3.
Compatible with VESA Dual Mode
It supports VESA Dual Mode, which allows you to switch between two modes: 4K (3,840×2,160) / 240Hz and Full HD (1,920×1,080) / 480Hz.
You can enjoy games with beautiful graphics such as RPGs and MMOs at 4K / 240Hz, and FPS or action games that require high-speed display at Full HD / 480Hz.
When displaying in Full HD, the screen size can be switched to 27 inches or 24.5 inches, allowing you to play at the optimal size for FPS games.
The response time achieves 0.03ms (GTG), providing crisp imagery even in scenes with intense movement.
Equipped with Three AI Features
It is equipped with the following three AI features to improve video and audio performance:
- AI Upscaling: The built-in processor upscales low-resolution content to 5K2K resolution in real time.
- AI Sound: Optimizes the acoustics according to the content, making sound effects such as footsteps clear.
- AI Scene Optimization: The AI recognizes the displayed content and automatically adjusts major image settings to optimize the display.
Equipped with a USB Type-C Port Supporting Up to 90W
It supports AMD FreeSync Premium Pro Technology and NVIDIA G-SYNC Compatible, which suppress tearing and stuttering.
It features USB Type-C (USB PD Max 90W), allowing you to handle display connection, power supply, and data transfer all together with a single cable.
It has built-in 7W+7W stereo speakers, enabling you to enjoy immersive sound by turning on the AI Sound feature.
It also supports 4-pole headphone output.
In addition, it features functions that support gameplay, such as OLED Care to prevent burn-in and the Live Color Low Blue Light feature to reduce blue light without color shifting.
