Your computer monitor is the device that connects to your PC, laptop, or console to provide the image. There are plenty of different types, sizes, and an array of features, such as Nvidia G Sync and AMD FreeSync ,that synchronise your refresh rate to your GPU. Overclockers UK stocks an extensive range of monitors perfect for PC gaming, console gaming, and work. All of which come in a huge variety of sizes such as 27 inch, 32 inch, 40 inch, and beyond.

Which Monitor Is Right For Me?


For modern AAA gaming, a larger resolution and screen size, such as 1440p or even 4K, with super high refresh rates, can be a great choice. What’s more, with features such as NVIDIA G-Sync and AMD FreeSync to reduce screen tearing at high refresh rates, you can game in confidence. Notably some gaming monitors even include addressable RGB to blend perfectly into your gaming aesthetic.

Professional Users - Graphics, Photo, Video

For professionals and creators' colour accurate, high-resolution monitors are ideal to help bring to life every detail and accommodate your application UI.

Console Gaming

Next gen consoles offer a truly exceptional gaming experience. Due to their ability to game at 4K with high FPS and refresh rates, a gaming monitor can be a superb upgrade to the living room TV.

Office & Home Users

Working from home, media browsing, and more can all be made easier with a high-quality 1080p monitor. Larger screen sizes offer more space for multiple windows, and with sizes up to 40 inch and beyond, you can level up your binge-watching experience.

Monitor Panel Types


TN panels can often support higher refresh rates at a lower price point, the trade-off being that they have a narrow viewing angle, and limited colour depth. Whilst this might be a deal breaker for some, they're excellent for gaming newcomers and home users - who will be sitting directly in front of their monitor and who won't require high colour accuracy.


IPS panels tend to come at a higher price point, but also offer far greater colour depth and great viewing angles. These are a prime choice of monitor for creatives and video editors where colour accuracy is paramount, and for gamers. Whilst they are usually more expensive, more IPS panels are available with high refresh rates and low input lag.


VA panels combine some of the features of both TN, and IPS whilst remaining a budget option. VA monitors offer higher colour depth than TN, alongside wide viewing angles. This makes VA monitors ideal for gamers.


OLED panels offer a truly outstanding and vivid image. Organic Light Emitting Diodes remove the need for a separate backlight or sidelight used in traditional monitors. These diodes are able to illuminate the pixels independently, allowing for unmatched colour performance, contrast ratios, and awe-inspiring visuals.


TFT is the technology that makes up most modern monitors and displays. Thin-Film Transistor (TFT) displays are a type of Liquid Crystal Display (LCD) that use transistors as individual pixels. TFT gaming monitors offer outstanding colour, response times, refresh rates, and contrast ratios. All of this makes them ideal for gaming, content creation, and productivity. Overclockers UK stocks a huge range of TFT monitors perfect for any application.


LCD monitors are available in three main types - VA, TN, and IPS. Each panel type offers different features, such as lighting, fast response times, high refresh rates, and exceptional colour accuracy. Overclockers UK stocks a huge selection of LCD monitors perfect for gaming, content creation, simulator PCs, and professional use.

Colour Depth and Colour Gamut

Colour depth and gamut are often confusing, with monitors stating various scores in different colour ranges such as Adobe RGB or sRGB. In simple terms, this is how accurate the colour on your screen is being displayed. This is a hugely important point for visual creatives - whether in video, photography, or print media - as having an inaccurate representation on your screen can significantly alter your finished product.

Additionally, you may also see various percentages before these names. This refers to how accurate the representation of that colour space is on a given monitor. For example, anything below 100% may appear washed out and unsaturated, whilst going above this may appear overly vibrant, and as expected - the closer to 100% you get, the more "true" the colours will appear.

Whilst Adobe RGB and sRGB produce more true-to-life colours, they do differ. Adobe RGB is favoured more for those producing graphics in professional grade printing - giving more accuracy to the final product. The one main drawback for this larger colour space is when uploading Adobe RGB images online, they will be converted to sRGB and potentially lose some colour information. The same can occur when printing on non-professional hardware. For photographers and digital artists, an Adobe RGB monitor might be the best choice, as colour profiles can be changed depending on the task.

sRGB (Standard Red, Green, Blue) dates back to the mid-1990s, and is still a great choice for all users, including professionals. It doesn't require conversion for use online, unlike Adobe RGB, and for professional print, is more than acceptable for colour-accuracy.

Size Matters

Choosing the right size monitor can be hard decision. Some people prefer having one gaming monitor and a second larger monitor for productivity. There is no right way to set up your desk, and choosing between one large monitor or even several smaller ones comes down to personal preference.

Your screen size is measured corner to corner, and will most often be simplified to 24 inch, 27 inch, 30 inch, and so on. For most users, this will answer the question of how big they can go. It is worth noting, that when you increase your screen size, it's wise to follow with resolution to have a sharp image on screen. For example, a 40 inch monitor with a 1080p resolution can look "soft" due to the pixel density. For larger monitors such as 40 inch we recommend a resolution of 4k or at least 1440p. Generally speaking, for gaming, you’ll want at least a 24 inch monitor with a resolution of 1080p. To view content more comfortably, we recommend 27 inch or above with a resolution of 1440p.

NVIDIA G-Sync and AMD FreeSync

These technologies are very similar and use the GPU to help smooth the graphics on the monitor, meaning that lower refresh rate monitors can avoid tearing. This happens because the monitor's refresh rate (Hz) is being dynamically changed to match the game's frame rate (FPS) as closely as possible.

Refresh Rates

Refresh rate is how many times a monitor updates the image each second. For home users, a lower refresh rate is fine. However, for gaming, the higher the refresh rate, the smoother the visuals will appear. Overclockers UK stocks an extensive range of monitors with high refresh rates such as 120Hz, 144Hz, 240Hz, and 360Hz.

Response Time

This is the time it takes for a pixel to change from one colour to another. Previously, it was measured in black-to-white (BTW), but more often, you'll now see grey-to-grey (G2G). A lower measurement of G2G means the monitor will appear less blurry when displaying fast-moving content. Overclockers UK stock a huge range of gaming monitors with response times as low as 1ms.

Monitors FAQ

What is a Monitor?

A computer monitor is the device that connects to your PC, laptop, or console to provide the visual output of your device.

How do I setup dual monitors?

On Windows, to setup two monitors, you simply need to plug both of the monitors into your graphics card (or motherboard if using an APU). Once you have both connected, simply right-click on the desktop and select “display settings”. In these settings, you can decide whether to duplicate, or extend your displays.

Is a second monitor worth it?

There is no correct answer to this question. Most people can survive on a single monitor set-up, but there is an advantage for two or more monitors, especially for gaming, creators, and professionals. For example, with two monitors, you can play a game whilst also monitoring your discord, stream chat, or even watch a YouTube video.

Should I get a curved monitor?

Curved monitors do give less distortion towards the edges, and can be more comfortable for users . The curve can give more immersion and easier pick-up in your peripheral vision. Larger curved monitors are great for simulation set-ups.

What is HDR?

HDR stands for High Dynamic Range. This means a display can produce a more "realistic" representation of colour, shadows, and even brightness. For example, the shadows will be less dark and undefined, and the highs will not be as blown-out. For this to happen, both the monitor and the content you’re playing or watching need to be compatible.
