Who it fits
Good fit for
You should consider this monitor if you play fast-paced competitive shooters or racing games. The 240Hz refresh rate and 0.03ms response time help you track targets with minimal blur. The 800R curve enhances peripheral vision, which is useful for immersion in single-player titles. If you use a PC with an NVIDIA or AMD GPU, the sync technologies ensure tear-free gameplay. The USB-C port with 65W power delivery also suits users who want to connect a laptop with a single cable.
Who should skip it
Look at another option if you prioritize a flat screen over a curved one. The 800R curve is steep and may not suit all desk setups or viewing preferences. You might also skip this if you need a 4K resolution, as this is a WQHD panel. Users who require a very small monitor will find the 39-inch size too large for limited desk space. Additionally, if you do not have a compatible GPU for G-SYNC or FreeSync, you will not get the full benefit of the sync features.
Verdict: The LG 39GX900A-B offers high-speed OLED performance with a steep curve for immersive gaming. It is best for competitive players who value refresh rate and response time over flat-screen aesthetics.
LG 39-Inch OLED Key Specs
Panel Type: OLED
OLED pixels emit their own light, allowing each one to turn off completely. This creates true blacks and an infinite contrast ratio, making shadows look deep and colors pop. You will notice better detail in dark scenes compared to LCD panels. This technology is ideal for cinematic gaming and media consumption where visual fidelity matters most.
Refresh Rate: 240Hz
The screen updates 240 times per second, showing more frames than standard 60Hz or 144Hz monitors. This results in smoother motion and less blur during fast-paced action. Competitive gamers benefit significantly from this speed, as it helps track moving targets more accurately. You get a fluid experience that reduces perceived input lag.
Response Time: 0.03ms (GtG)
Gray-to-gray response time measures how quickly a pixel changes color. At 0.03ms, transitions are nearly instantaneous, minimizing ghosting and trailing artifacts behind fast objects. This speed complements the high refresh rate, ensuring that the extra frames are rendered clearly. It is crucial for fast shooters where clarity determines performance.
Resolution: WQHD
WQHD typically refers to a 3440x1440 resolution, offering more horizontal pixels than standard 1080p. On a 39-inch screen, this provides sharp text and detailed imagery without the heavy GPU load of 4K. You gain a wider field of view, which is advantageous for immersive games and multitasking workflows.
Sync Technology: FreeSync Premium Pro & G-SYNC Compatible
These technologies synchronize the monitor's refresh rate with your graphics card's frame output. This eliminates screen tearing and stuttering, ensuring smooth visuals even when frame rates fluctuate. FreeSync Premium Pro adds low framerate compensation, while G-SYNC compatibility offers similar benefits for NVIDIA users. You get consistent performance across different PC configurations.
Design And Build Overview
The listing describes the LG Ultragear 39GX900A-B as a white unit with a 39-inch WQHD OLED panel. It features a steep 800R curve. This curvature wraps around your field of view. According to the listing, this design enhances peripheral vision for deeper immersion. The anti-glare OLED surface minimizes reflections. This helps you stay focused on objectives without visual distractions from room lighting.
Physical dimensions are specific. The monitor measures 35 inches in width, 23.9 inches in height, and 12.7 inches in depth. It weighs 25.4 pounds. These figures indicate a substantial footprint. You need a desk that can support this width and weight. The white finish may require regular cleaning to maintain its appearance. The build suggests a stationary setup rather than a portable one.
Connectivity options include HDMI 2.1, DisplayPort 1.4, and USB Type-C. The USB-C port supports up to 65W power delivery. This allows for single-cable setups with compatible laptops. You can charge your device while transmitting video and data. The layout supports high-res, high-frame gameplay. It also simplifies cable management for serious gamers who want a clean desk. The design prioritizes both visual immersion and functional connectivity.
Setup And Daily Use Guide
Setting up this monitor requires connecting the included cables to your source device. You can use HDMI 2.1, DisplayPort 1.4, or USB Type-C. The USB-C port supports up to 65W power delivery. This allows you to connect a laptop with a single cable for video and power. The unit weighs 25.4 pounds and measures 35 inches wide. Ensure your desk can support this weight and width.
Daily use involves navigating the on-screen settings to match your system. The monitor supports both FreeSync Premium Pro and G-SYNC Compatible technology. You must enable the correct sync mode in your graphics card software to match the monitor’s capabilities. This ensures frames render smoothly without tearing. The 240Hz refresh rate and 0.03ms response time are designed for fast-paced games. These specs reduce motion blur and input lag.
The 800R curve places the screen edges closer to your eyes. This geometry may require you to position the monitor centrally to avoid neck strain. The anti-glare surface helps reduce reflections from overhead lights or windows. You should adjust the brightness to suit your room’s lighting. The OLED panel offers high contrast and deep blacks. This enhances visibility in dark game environments. The built-in tools like Black Stabilizer and FPS Counter are accessible via the menu. You can toggle these features to gain a tactical advantage. The display handles high-resolution content with sharp detail due to its WQHD resolution.
Before You Buy This Monitor
Owning this 39-inch OLED requires attention to screen care. OLED panels can suffer from image retention if static elements remain on screen for too long. You should enable pixel shift and screen savers to protect the panel. Keep the area around the monitor clean to maintain the anti-glare surface. Dust on the screen is more visible on OLED due to the deep blacks. Use a microfiber cloth for cleaning. Do not use harsh chemicals. Check your GPU drivers for optimal FreeSync and G-SYNC compatibility. This monitor fits well in a high-end gaming setup. It pairs best with powerful PCs that can push 240Hz at WQHD. If you play slower games, the high refresh rate may not be fully utilized. Consider your desk space. The 39-inch width is significant. Ensure your setup can accommodate the curve and size comfortably alongside other gear.
Check before you buy
- Verify your GPU supports 240Hz at WQHD resolution.
- Enable pixel shift to prevent image retention on OLED.
- Check desk depth for the 800R curve fit.
- Ensure HDMI 2.1 or DP 1.4 cables are available.
- Clean screen with microfiber cloth only.
