FAQ

Q.

How to pick a gaming monitor?

A.

Start with your priorities. Want crisp visuals? Go for 4K resolution. Need ultra-smooth motion? Prioritize a high refresh rate (144Hz or more) and low response time. If you're after deep contrast and color accuracy, consider OLED or Nano IPS, Nano IPS black panels. Don’t forget adaptive sync tech like NVIDIA G-SYNC or AMD FreeSync™ Premium to eliminate screen tearing. 

LG’s UltraGear™ series offers a range of gaming monitors tailored to your playstyle—from casual console gaming to high-intensity PC competition.

Q.

What is the refresh rate of a gaming monitor?

A.

Refresh rate, calculated in Hertz (Hz) refers to how many images in a display are updated within one second. For example, a 120 Hz indicates that the display refreshes 120 times per second. Gaming monitors with high refresh rates offers smoother visuals with less screen tearing. 

Q.

How many hertz is good for gaming?

A.

For most gamers, 144Hz hits the sweet spot for fluid, responsive gameplay. Competitive players may want even faster refresh rates like 240Hz for that extra edge in fast-paced shooters or esports titles. LG’s lineup of UltraGear™ Gaming Monitors include models that go from 144Hz to 480Hz (when used in dual mode, LG's models support 165Hz and 330Hz OR 240Hz and 480Hz)*, all designed to keep up with the action while minimizing lag and screen tearing. 

 

It depends on what—and how—you play. Many gamers go with 144Hz for fluid, responsive gameplay. Competitive players may want faster refresh rates like 240Hz for that extra edge in fast-paced shooters or esports titles. LG’s lineup of UltraGear™ Gaming Monitors includes models that go from 144Hz to 240Hz and 480Hz, all designed to keep up with the action while minimizing lag and screen tearing.

 

*Actual refresh rates may vary depending on computer graphics specifications and configurations.

Q.

What is the difference between IPS and VA panels?

A.

IPS panels deliver an impressive color performance. They are best for gamers who like to take in the visuals of the game as intended by the artists. They are ideal for RPG and open world games.

VA panels have the most contrast among the LCD varieties. While they do not have the response time of TN panels, they perform nearly as well. 

Q.

What is the best curved monitor for gaming?

A.

If you’re looking for a more immersive gaming experience, curved gaming monitors are a great choice. The curvature helps keep your eyes naturally focused on the center of the screen, which can make longer gaming sessions more comfortable.

 

LG's UltraGear evo GX9 (39GX950B) gaming monitor features the world’s first 39-inch 5K2K OLED display with a 1500R curved ultrawide design. Its 1500R curvature aligns more naturally with your field of view, helping maintain clarity from the center to the edges of the screen. The 39‑inch ultrawide format provides an ideal screen size for immersive gameplay. It also features AI Upscaling technology that lets you enjoy 5K2K at 165Hz without frame drops, even without a high‑end graphics card. In addition, AI Scene Optimization automatically detects your usage scenario and adjusts the picture settings for optimal image quality.

With LG’s own DQ‑C2 chipset, the monitor is equipped with AI Sound technology that makes sound effects, background music, and voices feel even more realistic.

The UltraGear evo G9 (52G930B) also features a 1000R curvature on its world’s largest 52-inch ultrawide display, providing an expansive field of view. Its tighter curvature enhances immersion across the ultrawide screen while maintaining visual clarity and viewing comfort from center to edge. It also features a 240Hz refresh rate for smooth, responsive gameplay.

Q.

Is 1440p or 4K better for gaming?

A.

Both have their strengths. For many gamers, 1440p (QHD) hits a sweet spot between resolution and performance, especially for competitive gaming where frame rate matters most. It’s easier to push higher FPS without overloading your GPU. 4K, on the other hand, is all about detail and immersion—perfect for single-player adventures or next-gen console play. LG’s UltraGear™ gaming monitors offer both QHD and 4K options, so whether you prioritize speed or stunning visuals, there’s a perfect fit for your setup.

Q.

Can I connect my monitor to my PC with a USB-C?

A.

Connecting your gaming monitor via USB-C* is simple—just plug one end of the cable of your gaming monitor into your device’s USB-C port, and you’re good to go. 

You can charge your laptop too if your PC is connected to your monitor with a USB-C port.

*Supported model may vary.

Q.

What is DisplayPort 2.1?

A.

DisplayPort 2.1*, which is the latest version of the DisplayPort standard, delivers ultra-fast data speeds for flawless high refresh rate gameplay. 

It is developed by VESA (Video Electronics Standards Association) to provide high-performance display connectivity for computers and monitors.

 

Many of LG’s latest models support DisplayPort 2.1, which doubles the bandwidth of DP 1.4. That means you get higher resolutions, smoother frame rates, and lower latency—perfect for fast-paced gaming. 

 

*Important Update: NVIDIA has released the GeForce Hotfix Display Driver 576.26 (April 28, 2025) to resolve screen blackouts when connecting to DisplayPort 2.1 on NVIDIA RTX 50 series GPUs. NVIDIA GPU users should download and install the latest display driver before connecting their DP2.1-supported monitors.

Q.

What is HDMI 2.1?

A.

With HDMI 2.1 supported, you’ll enjoy features like Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), and support for 4K at up to 120Hz. Whether you’re gaming on a console or PC, these upgrades give you the flexibility and performance to match any setup.

Q.

What are the new 2026 gaming monitors lineup from LG?

A.

LG’s 2026 UltraGear lineup introduces a range of high-resolution gaming monitors designed to support both immersive gameplay and productivity. The lineup spans multiple panel technologies, screen sizes, and aspect ratios, offering resolutions up to 5K2K. Select models also incorporate on-device AI upscaling and AI scene optimization to help enhance image clarity across different use cases.

Q.

Why should I consider buying a 1000Hz gaming monitor?

A.

A 1000Hz gaming monitor can help competitive players gain an edge when reaction speed and precision matter most. Higher refresh rates help improve smoothness, motion clarity, and responsiveness, supporting quicker reactions and greater aiming precision in competitive FPS games.

 

LG's UltraGear™ 25G590B is the World's First Native 1000Hz FHD Gaming Monitor*, designed specifically for this type of competitive gaming. Its 24.5-inch Full HD IPS display, ultra-fast 0.5ms GtG response time, MBR Pro (Motion Blur Reduction Pro), and native 1000Hz refresh rate work together to help players track fast-moving opponents more effectively during fast-paced gameplay. The monitor can also be overclocked to 1100Hz** for even higher refresh-rate performance.

 

Unlike dual-mode displays, it delivers native 1000Hz performance in Full HD at all times, helping players maintain a consistent esports-focused experience without changing display settings. Furthermore, it delivers a buttery-smooth gaming experience with NVIDIA G-SYNC® Compatible and AMD FreeSync Premium support, while built-in AI features like AI Scene Optimization and AI Sound enhance your strategy and immersion.

Designed for competitive esports gaming, the UltraGear™ 25G590B delivers the speed, precision, and consistency that competitive gamers demand.

 

*Based on publicly available information as of May 19, 2026 (KST), among gaming monitors introduced by consumer brands.

**Overclocked 1100Hz operation may limit Adaptive-Sync functionality, as AMD FreeSync™ Premium is not supported and NVIDIA G-SYNC® compatibility is only certified at 1000Hz, where performance is guaranteed.

1100Hz overclock is evaluated based on internal testing.

Q.

What is the difference between 500Hz and 1000Hz refresh rates in gaming monitors?

A.

The key difference between 500Hz and 1000Hz gaming monitors is that a 1000Hz refresh rate delivers visual updates twice as often as a 500Hz refresh rate. A 500Hz gaming monitor refreshes the image every 2ms, while a 1000Hz gaming monitor cuts that refresh interval to 1ms for more frequent visual updates. The difference may not stand out in every game or for every player, but it can become more meaningful in competitive FPS moments where fast mouse turns, target tracking and full-screen camera movement make visual timing harder to read.

 

LG UltraGear™ 25G590B, the world's first native 1000Hz FHD Gaming Monitor*, is designed to maximize this advantage. It delivers native 1000Hz Full HD performance and pairs this with an ultra-fast 0.5ms GtG response time on an IPS panel. This helps deliver rapid 1ms refresh intervals with enhanced motion clarity and minimal ghosting, helping support smoother motion clarity, sharper visual confirmation and consistent responsiveness in esports gaming. Real-world benefits depend on game frame rate, PC performance, settings and player sensitivity, making 1000Hz most relevant for players who want to reduce visual delay in high-speed competitive scenarios.

Q.

What is the best LG gaming monitors for esports?

A.

LG's UltraGear™ 25G590B stands out as LG's most esports-focused gaming monitor.

 

As the World's First Native 1000Hz FHD Gaming Monitor*, LG's UltraGear™ 25G590B is built specifically for esports competition. Its 24.5-inch Full HD display features the screen size widely adopted in esports, supporting quick situational awareness during gameplay.

 

The 25G590B's 1000Hz refresh rate, ultra-fast 0.5ms GtG response time, and MBR Pro (Motion Blur Reduction Pro) support the fast visual response and target tracking required in competitive play. Native 1000Hz performance at Full HD also allows players to train and compete under consistent visual conditions without changing display settings.

 

Designed for competitive esports gaming, its compact, esports-focus design enables a gaming setup tailored for competitive play. The 25G590B's stand base has been redesigned to occupy 49% less area compared to a similar existing model, 25G550B. This enables users to maximize the available space in front of the monitor for flexible keyboard and mouse positioning, making it ideal for esports environments.
