Whether it will be your main display or a secondary screen, if you haven’t treated yourself to a new monitor in a while, then now is the perfect time to do so. You can get excellent image quality without spending too much and the latest designs are better looking than ever.

We’ve reviewed and ranks various monitors here and while some may be a few years old, don’t worry, the technology doesn’t move quickly like phones so they’re still perfectly suitable for the job. If anything, they’re more likely to be reduced in price and a bargain.

Your buying guide for the best monitors in 2020

The first decision is what size you want. Even 24in screens are cheap, or can be, so there’s no point in going smaller unless you have to because of space limitations. 

In many cases, the once thick surrounding bezel has been removed in favour of a tidy, nearly frameless design and modern backlight technology allows for much slimmer, neater displays. This is handy if you want a multi-monitor setup, where the gaps between the displays will be as thin as possible. Some models are also available in different colours.

The panel should be supportable at a comfortable height, which means you’ll want a fully adjustable stand.

4K and Ultra HD monitors

4K TVs have come down in price a lot, but they’re still commanding a decent premium if you want a 4K monitor for your PC.

4K is the same as Ultra HD, as explained hereThey pack in 3840×2160 pixels, which is four times more than a Full HD 1920×1080 screen.

Having this many pixels means you see more detail in photos (without zooming in) and you can watch 4K video on Netflix, Amazon and YouTube. If your PC is up to it, you can even run your games at this resolution, which makes for very sharp and realistic graphics.

Screen types

Even if you’re going for a budget screen, the performance of the display itself will be important. Perhaps the biggest deciding factor here will be your choice of panel technology – and it boils down to twisted-nematic (TN) panels versus everything else.

A TN panel costs less to make and can produce some decent performance results in terms of contrast ratio and the super-fast response times craved by serious gamers. They are, however, let down by restricted viewing angles, which means the brightness and colour of the picture can appear to shift if not viewed straight on. Any movement of your head is likely to make this apparent.

All the non-TN panels in this round-up use in-plane switching (IPS) or plane-line switching (PLS) panels, which typically offer a vastly superior viewing experience and are better suited for general-purpose use. An IPS/PLS screen is often favoured by photo- or video-editors, as they offer better colour accuracy.

Brightness rating is a manufacturers’ arms-race figure that can be largely ignored, so long as the result is above around 200 candela per square metre (cd/m2).

Much more important is contrast ratio, the difference between the very brightest and darkest images a screen can show. Around 500:1 is the starting point for believable imaging, though you should beware brands that promise the earth with millions:1 ratios.

Colour gamut, the spectral spread of reproduced colour within our perceptual limits, has been getting worse in modern displays, tumbling first with the introduction of LCD to replace glass-tube CRT sets. Then colour gamut shrunk again when traditional CCFL backlights were tossed out in favour of white LED technology.

Full coverage of the PC-standard called sRGB is a good first target for decent colour range; Adobe RGB is a more challenging spec that nevertheless gets closer to the vast range of colour the human eye can appreciate.

Colour accuracy meanwhile is about reproducing the exact hue as intended, rather than a rough approximation. Deviation from true colour fidelity is represented by a Delta E figure, lower numbers better. Close to or below 1.0 is a good achievement.

Response time is often quoted in the manufacturer’s specifications, another area for brand one-upmanship, but even for gamers there is little need to seek vanishingly low figures such as 1- or 2 millisecond (ms). The intrinsic lag of the monitor’s electronics is typically well in excess of 10ms, so the added time for liquid crystals to complete their transition as they turn on/off has become inconsequential.

Inputs

The monitors reviewed here all offer at least two inputs, and this will determine what sort of equipment you can hook up to your monitor. Some still have the ageing VGA connector, which should be avoided if at all possible, and instead look for digital inputs, such as DVI, HDMI and DisplayPort. The latest models offer USB-C which can charge a laptop at the same time as transmitting video to the monitor.

Multiple inputs allow you to connect more than one device at a time and switch between them using the monitor’s control buttons – you may want to connect your laptop and a gaming console or a Blu-ray player without having to unplug cables each time.

The most useful connector on monitors is either DisplayPort or HDMI, as they combine digital picture information with digital audio – allowing you to connect up both sound and vision with a single cable. DisplayPort is becoming more common on both Macs and Windows PCs, although you won’t to find such a connector on home AV equipment. DisplayPort is also the best choice for 4K monitors or those with high refresh rates.

The DVI connector provides a high-quality digital video input, but doesn’t carry sound. Some monitors offer ‘dual-link DVI’, based on two DVI streams in one DVI connector. DVI remains popular with gamers who believe that this digital interface cable has less latency and so will better their reaction times.

If you have an Android phone or tablet, you might want to look for an HDMI port with MHL support, but that’s only if you want to mirror your phone’s screen on the monitor.
