Key specs explained for LG 39GX950B-B
Panel Type: OLED
OLED panels use organic light-emitting diodes that produce their own light. This allows for perfect black levels because pixels can turn off completely. You get infinite contrast, making dark scenes in games look deeper and more realistic. This technology also offers faster response times than traditional LCDs, reducing motion blur. If you prioritize visual fidelity and deep blacks over absolute peak brightness, this panel type is ideal for immersive gaming and media consumption.
Resolution: 5120x2160
This 5K2K resolution provides a pixel density of 143 PPI, ensuring sharp text and detailed images. The high pixel count eliminates the screen door effect common in lower-resolution ultrawides. You benefit from crisp visuals in both gaming and productivity tasks, such as editing photos or coding. Compared to standard 1440p ultrawides, this resolution offers significantly more screen real estate and clarity, making it suitable for users who want a high-end desktop experience without scaling issues.
Refresh Rate: 165Hz
A 165Hz refresh rate means the screen updates 165 times per second, delivering smoother motion than standard 60Hz or 144Hz displays. This reduces stuttering and tearing in fast-paced games, providing a competitive advantage in shooters or racing titles. While not as high as 360Hz monitors, 165Hz strikes a balance between smoothness and resolution. You will notice improved fluidity in animations and gameplay, making it a versatile choice for both casual and serious gamers.
Response Time: 0.03ms (GtG)
The 0.03ms gray-to-gray response time indicates how quickly a pixel changes color. This extremely low figure minimizes ghosting and trailing artifacts during fast movements. For competitive gamers, this ensures that fast-moving objects remain distinct and clear. Compared to IPS panels that may struggle with motion clarity, OLED technology excels here. You will experience sharper visuals in action-heavy scenes, enhancing your ability to track targets and react quickly in high-intensity gaming scenarios.
Aspect Ratio: 21:9
The 21:9 aspect ratio provides a wider field of view than standard 16:9 monitors. This expansive screen allows you to see more of the game world or fit multiple windows side-by-side for productivity. You gain an immersive experience in supported games and increased workspace efficiency for multitasking. Compared to narrower displays, this format reduces the need to constantly scroll or switch windows. It is particularly beneficial for strategy games, video editing, and users who value a seamless, continuous visual canvas.

Before You Buy This Monitor
Owning this LG 39-inch UltraGear requires specific hardware preparation. You must verify your graphics card supports DisplayPort 1.4 or HDMI 2.1 to drive 5120x2160 at 165Hz. Without a compatible output, you cannot utilize the full resolution. The built-in AI upscaling helps older games, but native 5K2K content delivers the best results. OLED panels benefit from pixel shifting and screen savers to prevent image retention, so enable these features in the OSD. This monitor sits uniquely in our 1 reviews due to its 39-inch size and 5K2K resolution. Most competitors offer either 16:9 4K or 21:9 4K. The 5K2K format provides sharper text and more vertical screen real estate than standard ultrawides. It suits creators and immersive gamers who need detail without switching monitors. If you primarily play competitive shooters, consider the Dual Mode for 330Hz performance. Otherwise, the 165Hz mode offers a balanced experience for single-player titles.
