A monitor can completely change how comfortable and productive your computer setup feels. The right screen gives you enough space to work, makes text easier to read and can provide a much better experience for everything from spreadsheets and video calls to photo editing and entertainment.
But choosing one is not always straightforward. A bigger screen isn't automatically better, and specifications such as 4K, IPS, 144Hz and USB-C can make comparing monitors unnecessarily confusing.
This guide focuses on what those specifications actually mean when you're choosing a monitor and, more importantly, which ones are worth paying for based on how you'll use it.
Start With What You'll Use Your Monitor For
Before comparing specifications, think about what you actually spend your time doing. A monitor for emails, web browsing and Microsoft 365 has very different requirements from one used for graphic design or gaming.
Monitors for Everyday Home Use
For general home computing, you don't need to chase the highest specifications.
A 24-inch or 27-inch Full HD monitor can be a great choice for browsing, emails, streaming and everyday tasks. If you regularly have several windows open at once, moving to a 27-inch QHD display can give you noticeably more usable workspace.
Monitors for Business and Office Work
When choosing business monitors for office work, comfort and productivity should usually take priority over headline specifications.
A 24-inch monitor is still a practical choice where desk space is limited, while 27-inch models give you more room for documents, spreadsheets and side-by-side windows.
Features such as height adjustment, USB-C connectivity and built-in USB hubs can also make a meaningful difference when you're sitting in front of the screen for hours every day.
For larger workspaces, two monitors or an ultrawide display can provide significantly more room for multitasking.
Monitors for Creative Work
Photography, video production, graphic design and other visual work place greater importance on image quality and colour reproduction.
An IPS panel is often a good starting point because of its strong colour performance and wide viewing angles. Higher resolutions such as QHD and 4K can also provide more detail and working space.
If colour accuracy is critical to your work, look beyond resolution and consider specifications such as colour gamut coverage and factory calibration.
Monitors for Gaming
Gaming monitors have their own set of priorities, including refresh rate, response time and adaptive sync technology.
A higher refresh rate can make movement appear considerably smoother, while lower response times help reduce visible motion blur.
We cover these areas in much greater detail in our dedicated Gaming Monitor Buying Guide, so it's worth reading that guide if gaming will be the main use for your new display.
What Monitor Size Should You Choose?
Monitor sizes are measured diagonally from corner to corner. The most common desktop sizes are 24, 27 and 32 inches, although ultrawide monitors can be considerably larger.
The best size depends on your available desk space, how far you sit from the screen and the resolution you're considering.
24-inch Monitors
A 24-inch monitor is a versatile choice for general computing and office environments.
It doesn't require a particularly deep desk and Full HD resolution usually works well at this size. They're also practical when creating a dual-monitor setup because two displays can fit comfortably on many desks.
27-inch Monitors
For many people, 27 inches provides an excellent balance between screen space and physical size.
Full HD is available at this size, but QHD resolution is particularly well suited to a 27-inch screen. It gives you more workspace and a noticeably sharper image without requiring the desk space of a larger display.
32-inch Monitors
A 32-inch display gives you a substantial amount of screen space and works particularly well with higher resolutions.
At this size, QHD can work well, but 4K becomes particularly attractive because the extra pixels help maintain a sharp image across the larger screen.
Make sure you have enough desk depth, though. Sitting too close to a large monitor can be less comfortable than using a slightly smaller screen.
Understanding Monitor Resolution
Resolution tells you how many pixels make up the image on your screen.
Higher resolutions can provide sharper text and images as well as additional workspace, but resolution should always be considered alongside screen size.
Full HD 1920 × 1080
Full HD, also known as 1080p, remains a sensible choice for everyday computing.
It works particularly well on 22-inch and 24-inch displays and is generally the most affordable option.
For email, web browsing, office applications and general home use, Full HD may be all you need.
QHD 2560 × 1440
QHD, sometimes called 1440p, provides significantly more pixels than Full HD.
It's particularly well suited to 27-inch monitors and gives you more room for documents, browser windows, spreadsheets and creative applications.
For someone who spends a large part of their working day at a computer, the jump from a 24-inch Full HD monitor to a 27-inch QHD display can be a worthwhile upgrade.
4K UHD 3840 × 2160
4K provides four times as many pixels as Full HD.
That extra resolution produces very sharp text and detailed images, particularly on 27-inch and 32-inch displays.
It's a strong choice for creative applications, detailed productivity work and anyone who simply wants excellent image clarity. Bear in mind that your computer also needs to support the monitor's resolution and required refresh rate through its available display connection.
IPS, VA or TN: Which Panel Type Is Best?
The panel technology inside a monitor affects characteristics such as colour reproduction, viewing angles, contrast and response time.
There isn't one panel technology that's automatically best for everyone.
IPS Panels
IPS displays are known for good colour reproduction and wide viewing angles.
They're an excellent all-round choice for business use, general computing and creative work, which is why IPS has become extremely common across modern monitors.
VA Panels
VA panels are particularly strong when it comes to contrast.
They can produce deeper blacks than many IPS displays, making them appealing for multimedia use and environments where strong contrast is important.
They're also commonly found in larger and curved monitors.
TN Panels
TN technology traditionally prioritises speed and affordability over viewing angles and colour reproduction.
While TN monitors still exist, improvements in IPS and VA technology mean buyers now have far more choice when looking for a fast display.
For most general-purpose buyers, IPS or VA will usually be the more relevant technologies to compare.
How Important Is Refresh Rate?
Refresh rate is measured in hertz (Hz) and tells you how many times a monitor can update its image each second.
A standard 60Hz display can refresh the image up to 60 times per second, while a 120Hz display can refresh up to 120 times.
Higher refresh rates are most closely associated with gaming, but the benefits aren't limited to games. Scrolling webpages, moving windows and navigating around the desktop can all appear smoother on a higher-refresh-rate screen.
For everyday office work, however, refresh rate shouldn't necessarily take priority over resolution, ergonomics or connectivity.
Monitor Connectivity: Check Before You Buy
It's easy to concentrate on the display itself and forget about how you're actually going to connect it.
Before buying, check the video outputs available on your desktop PC or laptop and compare them with the monitor.
HDMI
HDMI is one of the most widely supported connections and is found on desktops, laptops, monitors, games consoles and many other devices.
The resolution and refresh rate available through HDMI can vary depending on the HDMI version supported by both devices.
DisplayPort
DisplayPort is common on desktop PCs and business monitors and is particularly useful for high-resolution and high-refresh-rate displays.
Some business monitors also support DisplayPort daisy chaining, allowing compatible monitors to be connected together rather than requiring a separate display cable back to the computer for every screen.
USB-C
USB-C can dramatically simplify a laptop-based workspace.
On compatible equipment, a single USB-C cable can carry video to the monitor while also transferring data and supplying power back to the laptop.
This means you can arrive at your desk, connect one cable and potentially have access to your display, keyboard, mouse, network and laptop charging.
Check the specifications carefully, though. Not every USB-C port supports video output or charging, and the amount of power a monitor can provide varies between models.
Should You Choose an Ultrawide Monitor?
Ultrawide monitors provide additional horizontal workspace and can be an alternative to using two separate displays.
They're particularly useful if you regularly work with several applications at once. You might have a spreadsheet open alongside a browser, or your email alongside a document without constantly switching between windows.
They're also popular for video editing, where the extra width provides more room for timelines.
An ultrawide isn't automatically better than two monitors, however. Some people prefer the natural separation provided by individual screens, while others prefer one uninterrupted workspace.
The right choice comes down to how you organise your desktop.
Curved vs Flat Monitors
Curved screens are most common on larger and ultrawide monitors.
The curve can help the outer edges of a wide display feel more naturally positioned around your field of view, which is one reason curved designs are popular on ultrawide screens.
For conventional 24-inch and 27-inch office monitors, a flat screen remains perfectly suitable for most people.
Rather than treating a curved screen as inherently better, consider it as part of the overall size and shape of the display.
Don't Overlook Monitor Ergonomics
If you use your computer for several hours every day, the physical adjustability of your monitor can be just as important as its display specifications.
Height Adjustment
Being able to raise or lower the screen makes it much easier to position your monitor comfortably.
A fixed stand can leave the display too low or too high depending on your desk and seating position.
Tilt, Swivel and Pivot
More adjustable stands can allow the display to tilt forwards and backwards, swivel from side to side or rotate into portrait orientation.
Portrait mode can be particularly useful for coding, reading long documents or working with vertically oriented content.
VESA Mounting
If you're planning to use a monitor arm or wall mount, check for VESA mounting compatibility.
A monitor arm can free up desk space and give you much greater flexibility over screen positioning, particularly with dual-monitor setups
One Monitor, Two Monitors or an Ultrawide?
There's no universal answer to how much screen space you need.
A single 24-inch or 27-inch display is enough for many users. If you're constantly switching between applications, though, additional screen space can make a substantial difference.
Two monitors give you clearly separated workspaces and are particularly useful when one application needs to remain visible while you're working in another.
An ultrawide provides a similar amount of horizontal space without the bezel running down the middle.
Before buying either option, check that your computer supports the number of displays and resolutions you intend to use.
Useful Monitor Features Worth Considering
Once you've settled on the fundamentals, there are several additional features that can help narrow down your choice.
Built-in speakers can reduce desktop clutter for everyday audio and video calls, although dedicated speakers or headphones will usually provide better sound.
A built-in USB hub can make connecting keyboards, mice, webcams and other accessories easier.
Some business monitors include Ethernet connectivity, allowing a USB-C monitor to effectively double as a docking station.
Picture-by-Picture and Picture-in-Picture functionality can also be useful if you want to display content from more than one computer or source on the same monitor.
Choosing the Right Monitor for Your Setup
Rather than looking for the monitor with the longest specification list, concentrate on the features that will make a difference to how you use your computer.
For general home use, a 24-inch Full HD display may provide everything you need.
For productivity, a 27-inch QHD monitor offers an excellent combination of screen space and sharpness.
For detailed creative work or a larger display, 4K becomes increasingly worthwhile.
And if you regularly work across several applications, consider a dual-monitor setup or an ultrawide display.
Connectivity matters too, particularly for laptop users. A USB-C monitor with power delivery can transform a desk full of cables into a much simpler single-cable setup.
Ultimately, the right monitor isn't necessarily the one with the highest resolution, fastest refresh rate or largest screen. It's the one that fits your desk, your computer and the way you actually work.
