While 4K gaming is often associated with traditional 16:9 monitors, ultra-wide displays can still play a key role. A 21:9 monitor ratio provides a wider screen than the traditional 16:9, offering an immersive experience ideal for strategy and simulation games without requiring excessive space. The 32:9 monitor ratio is two 16:9 screens side by side, ideal for multitasking but less practical for gaming due to the extreme width.1

If you prefer a wider field of view, 21:9 ultra-wide monitors are the sweet spot for most gamers. They offer a balance between screen real estate and practicality, enhancing the gaming experience without the drawbacks of extreme width. On the other hand, while 32:9 ultra-wide monitors provide unmatched multitasking capabilities, their gaming benefits are more niche and require additional tweaks for compatibility. If you're looking for a 5K gaming monitor, explore the LG Ultra-Wide 40WP95CP-W for an immersive 5K2K OLED gaming experience.2
A 4K monitor delivers a high-resolution experience with 3840x2160 pixels, offering four times the detail of a standard 1080p display.3 This increased clarity enhances visuals, making in-game environments more immersive and lifelike. If you prioritise visual fidelity and have a capable gaming setup, a 4K monitor can significantly enhance your gaming experience.

For gamers seeking a true-to-life experience – such as from story-driven or cinematic games – and those eager to future-proof their setups, a 4K gaming monitor is a compelling choice.

Compared to lower-resolution options like 1080p or 1440p, a 4K monitor boasts sharper textures, reduced jagged edges (aliasing) and smoother lines, creating more realistic visuals. While gamers don’t need a 4K monitor, for RPGs, adventure and open-world games, the visual clarity and immersion could be worth it.
Typically higher refresh rates provide smoother gameplay.4 For high-intensity gaming scenarios, step up to a 144Hz or 240Hz 4K gaming monitor. LG UltraGear™ OLED monitors support 240Hz refresh rates, ensuring ultra-smooth visuals for competitive gaming.
Let’s look at some of the 4K 16:9 monitor options available from LG:
The LG UltraGear™ 32GS95UV-B is a high-performance 32" 4K UHD OLED gaming monitor with VESA DisplayHDR True Black 400 and DCI-P3 98.5%, delivering vivid visuals and exceptional colour accuracy. It features a 240Hz refresh rate, 0.03ms response time, and dual-mode technology (4K at 240Hz or FHD at 480Hz). NVIDIA G-SYNC, AMD FreeSync™, DTS Virtual: X™ speakers, and anti-glare technology ensure immersive, distraction-free gameplay.5
The LG 32UN650K-W is a 31.5" UHD 4K monitor designed for immersive visuals and ergonomic comfort. With a 60Hz refresh rate, 5ms response time, AMD FreeSync™, HDR10, and DCI-P3 95%, it delivers smooth, tear-free gameplay and vibrant colours. Its Dynamic Action Sync reduces input lag, while the adjustable ergonomic stand enhances usability.6
In fast-paced games like shooters and esports, players want to prioritise frame rates and 144Hz 4K monitors, and 240Hz 4K monitors or higher can achieve smoother motion and faster reactions.3 In more cinematic games the preference may be for ultra-sharp visuals rather than FPS (frames per second).

4K gaming has slightly higher latency because more pixels need to be rendered, requiring more GPU power. Higher refresh rates (120Hz, 144Hz, 240Hz) help reduce latency. Lower resolutions tend to have less motion blur at higher refresh rates, improving motion clarity in FPS and esports games.
Displays that support Variable Refresh Rate (VRR) help maintain smooth gameplay even when FPS fluctuates, reducing lag. With LG’s NVIDIA G-SYNC compatibility, the refresh rate adapts to the FPS.

LG UltraGear™ monitors such as the 32GS95UV-B 4K 240Hz gaming monitor have a Unity Hexagonal Design and a swivel, tilt and height adjustable stand to enhance user comfort. The space-saving L-shaped stand minimises desk clutter. Similarly, 4K 60Hz monitors such as the LG 31.5" 32UN650K-W also feature an ergonomic design with a One-Click stand for easy setup, with adjustable height and tilt.
LG's Smart Energy Saving function automatically adjusts monitor brightness based on on-screen content. This reduces energy usage during darker scenes while maintaining image quality – and extends monitor lifespan and reduces environmental impact.7
