40 Inch Monitors


Choosing the right monitor is just as important as selecting PC components. Overclockers UK stocks a huge range of 40 inch monitors with features such as NVIDIA G-Sync, AMD FreeSync, high refresh rates, and more. 40-inch gaming monitors can provide a great amount of screen real estate for real-time strategy games, outstanding colour and contrast ratios for the latest RPGs, and a competitive edge in esports titles with super low response times.

Monitor Resolution Explained

Monitor resolutions are usually either 1080p, 1440p, or 4K. The higher the resolution, the more CPU and GPU processing power you'll need to get a stable FPS. If you want to achieve high frame rates to take advantage of a high refresh rate monitor, you'll either need a very powerful PC or a lower resolution. For larger monitors, you will need to choose a higher resolution option as the number of pixels per inch (PPI) will be lower. This avoids the risk of gaming with softer or blurry images. We recommend using at least a 1440p or 4K resolution for a 40 inch monitor.

NVIDIA G-Sync is designed to provide a smooth, ultra-fast gaming experience by syncing the monitor's refresh rate to your NVIDIA GPU. This helps to remove screen tearing, display stutter, and input lag. Thanks to this, you can enjoy a competitive edge over your competition as well as sharp and smooth gameplay.


Similar to NVIDIA G-SYNC, AMD FreeSync allows for GPUs and APUs to be synced to the monitor's refresh rate, providing notably less screen tearing, input lag, and display stutter. This technology helps to create a better gaming experience in fast-paced AAA and esports titles.

Monitor Refresh Rates Explained

For gamers looking to get competitive in titles such as Valorant, CS:GO, and the latest Call of Duty, a high refresh rate 40 inch gaming monitor can help you get the edge you need. Simply put, refresh rates are defined by the maximum number of times a screen can refresh the image. A higher refresh rate accompanied by high FPS allows for notably reduced motion blur, allowing you to better keep your eye on the target.
