How to pick a gaming monitor?
Start with your priorities. Want crisp visuals? Go for 4K resolution. Need ultra-smooth motion? Prioritise a high refresh rate (144Hz or more) and low response time. If you're after deep contrast and colour 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 play style—from casual console gaming to high-intensity PC competition.
What is the refresh rate of a gaming monitor?
Refresh rate, calculated in Hertz (Hz) refers to how many frames are shown within one second. For example, a 120Hz refresh rate indicates that the display refreshes with a new frame 120 times per second. Gaming monitors with high refresh rates offer smoother visuals with less screen tearing.
How many hertz is good for gaming?
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 240Hz and beyond (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 minimising lag and screen tearing.
*Actual refresh rates may vary depending on computer graphics specifications and configurations.
What are the differences between OLED, IPS, and VA panels?
OLED panels emit their own light at the pixel level, delivering near-perfect blacks, exceptional contrast, and vivid colours. They also offer ultra-fast response times, making them ideal for high-end gaming monitors, premium TVs, and professional video editing.
IPS panels are known for their accurate colour reproduction and wide viewing angles, maintaining clear images from various positions. This makes them well-suited for office work, design, and gaming. Their excellent colour accuracy is especially appealing to gamers who want to experience visuals exactly as the developers intended.
VA panels boast the highest contrast ratio among LCD types, providing an immersive experience for watching movies and videos. While not as fast as TN panels, they offer nearly comparable performance.
Should I get a curved monitor?
If you want a more immersive gaming experience, curved gaming monitors are a great choice. The curvature helps keep your eyes focused on the center of the screen naturally, which is great for long gaming sessions.
LG's UltraGear GX9 supports 800R curvature and 21:9 ultrawide aspect ratio, delivering immersive visuals and an ideal viewing distance. At a 800mm viewing distance, its 800R curvature creates a viewing angle of 90 degrees across both the center and the edge - pulling you deeper into the game.
Is 1440p or 4K better for gaming?
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 prioritise speed or stunning visuals, there’s a perfect fit for your setup.
Can I connect my monitor to my PC with a USB-C?
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.
What is DisplayPort 2.1?
DisplayPort 2.1, the latest version of the DisplayPort standard, delivering 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.
*Note : We have received numerous reports from users of NVIDIA 50-series graphics cards experiencing screens turning off when using DisplayPort 2.1 with 10-bit or 12-bit settings. If you are experiencing the same, as a temporary workaround, you can switch the DisplayPort input to 1.4 in your monitor's OSD menu or adjust the colour setting to 8-bit in the NVIDIA Control Panel. This issue has been reported to NVIDIA, for a more permanent solution.
What is HDMI 2.1?
With HDMI 2.1 support, 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.
