“Whether it is studying, working, or gaming, many consumers have a new-found consideration for their long-neglected monitors as uncertainty about the office and school attendance persist,” said IDC research manager Jay Chou. “With inventory still at healthy levels and enticing promotions for gaming as well as bigger displays, IDC believes the solid momentum should last well into the first half of 2021,” Chou added. 
Having a larger display is obviously easier on the eye when you’re staring at the screen all day long, and can also help to reduce neck and back problems as you don’t have to keep bending over your laptop while working. 
There are other key factors as well, with size being the most obvious. If you’re simply running Microsoft Office and firing off emails to colleagues, then a low-cost 21-inch or 24-inch monitor might well be adequate (especially if it’s hogging your kitchen table). However, 27-inch monitors are increasingly popular – and increasingly affordable, too. Larger screens are obviously good for graphics work or presentations, but number-crunching software such as Excel can also benefit from as much screen space as possible.  Cheaper monitors tend to be limited to FHD resolution (1920 x 1080 pixels) and that’s acceptable for web browsing or simple word processing and spreadsheet work. However, higher resolutions such as QHD (2560 x 1440) provide more room for browsing through documents and having multiple documents or windows on-screen at the same time. Meanwhile, 4K or UHD displays (3840 x 2160) are tempting, and pretty much essential for graphics and video software, but remain something of a luxury for routine office work.

Many laptops and PCs use either HDMI or DisplayPort to connect to external displays, although there may be a few old PCs still floating around that use the now-ancient VGA or DVI interfaces. And, of course, many new laptops (PC and Mac) include USB-C, which is ideal for monitors in use at home as a single USB-C cable can provide video and data connections, and even charge your laptop too.
Acer’s ConceptD displays are quite expensive and are primarily designed for professional graphics, design and video work. The CP5 is Acer’s mid-range 27-inch model, priced at $599.99. Its 2560-by-1440 resolution (108.8ppi) is relatively modest, but the CP5 supports 99% of the Adobe RGB color standard, along with HDR 600. There are three video input options – HDMI, DisplayPort and USB-C – to provide compatibility with a wide range of devices, and the USB-C port can charge your laptop at the same time.   The 144Hz refresh rate will be easy on the eye, and the display also includes a light sensor that automatically adjusts brightness levels as the ambient light changes throughout the day. The CP5 includes a hood that helps to block out external light sources and glare while you’re working. Video editors who need 4K resolution can opt for the top-of-the-range CP7, which costs around $2200 – although that’s still a lot cheaper than Apple’s Pro Display XDR.  Pros:

Excellent color volumeUSB-C charging and video output144Hz refresh rate

Cons:

144Hz through DisplayPort only

A large screen is great for graphics work or delving into large spreadsheets, but sometimes a smaller, portable display can come in handy – especially if you’re quickly trying to fire off a few emails on a smartphone or tablet while working from home.  AOC makes a number of portable displays, all with 15.6-inch screens and 1920-by-1080 resolution (141.2ppi). The 16T2 is the top-of-the-range model, priced at $289.99, but it’s packed with useful features. The screen measures just 8.5mm thick and weighs 1kg, so it’s easy to carry around at home or in a bag when you’re travelling. It includes two USB-C ports and micro-HDMI to provide compatibility with a wide range of devices and has its own built-in battery so that it doesn’t drain your laptop’s battery. There’s a small set of stereo speakers built-in, and the display is touch-sensitive too – when connected via USB-C – allowing you to jot down notes and annotations while you’re working quickly. Pros:

Decent touchscreen size2 USB-C portsIntegrated speakers

Cons:

No stylus includedThe screen is somewhat dim at 250 nits

AOC’s ‘Basic’ range focuses on providing large-screen displays at a competitive price. The 27B2H is the successor to last year’s 27B1H and manages to offer even better value for money, with a 27-inch display priced at just $179.99.   The specification is fairly basic too, with just 1920-by-1080 resolution (81.6ppi), although that’s still adequate for mainstream office software such as Word and Excel and Zoom calls when you’re working from home. The 27B2H also provides a 75Hz refresh rate, along with flicker-free and ’low-blue’ modes to help reduce eye strain while you’re working. There’s no USB-C or DisplayPort interfaces, so it’s not the best choice for newer laptops and PCs, but the HDMI and VGA ports will be handy for people who are still making do with older devices. The low price means there are no built-in speakers, but there’s a 3.5mm audio jack for external speakers or headphones. Pros:

Great priceGreat picture qualityBlue light filter

Cons:

No integrated speakersNo DisplayPort connection 

If you’re burning the midnight oil working from home, then you may appreciate a display such as BenQ’s Eye-care GW2480. As well as the blue light and flicker-free filters now offered by many monitors, the GW2480 has a number of ‘brightness intelligence’ features that are designed to enhance visibility and reduce eye strain.  A built-in sensor monitors ambient light levels in the room and adjusts the screen brightness for comfortable viewing. It can also analyze the image being displayed on the screen itself and enhance darker areas or tone down harsh, bright parts of the image. And, for people with color vision problems, there are filters that allow you to adjust the levels of red and green displayed on the screen.  Prices start at $119.99 for the 24-inch model shown here, which has 1920 by 1080 resolution (92.6dpi). A 27-inch model, the GW2780, is also available for $179.99.  Pros:

Adaptive screen brightnessColorblind filtersIntegrated speakers and cable management channels

Cons:

Somewhat dim at 250 nits

Video conferencing has been the key application for remote workers during the pandemic, and Dell’s P2418HZ is ready-made for that purpose.   The 23.8-inch display is fairly conventional, with 1920 by 1080 resolution (92.6dpi), and at $315.41, the P2418HZ is pricey for a display with modest specifications. However, it’s loaded with features that will be handy for video conferencing and general office use.  The video side of things is handled by an integrated 2MP webcam, which is certified for use with Windows Hello and Skype for Business. There’s a built-in set of stereo speakers (2 x 5W) and a 3.5mm combo audio jack for headphones or microphones. The display can pivot into the upright (portrait) position for talking-head video sessions, and there’s also an integrated USB hub with four USB 3.0 ports for all your office peripherals. The P2418HZ includes VGA, HDMI, and DisplayPort for the video connection, but there’s no USB-C. Pros:

Integrated webcam and speakers4 USB portsTilt and pivot

Cons:

No USB-C portsDisappointing 60Hz refresh rate 

The Dell E2720H that we covered last year is still available from Dell if you’re after a low-cost ($174.99) 27-inch 1920-by-1080 (81.6ppi) display for working from home. The newer Dell S2721DS is a little more expensive, at $299.99, but it steps up to a more useful 2560-by-1440 resolution (108.8ppi), which will be ideal for running Microsoft Office and other productivity software. The stand allows you to adjust the height, tilt and even rotate the screen into the upright (portrait) position if you need to, and there’s a built-in set of stereo speakers as well.  The display provides three input options for connecting multiple devices – two HDMI ports and a DisplayPort –, and the S2721DS supports a 75Hz refresh rate to reduce eye strain, along with a ComfortView mode that reduces blue light emissions. There’s also a tempting 4K (3840 x 2160, 163.2ppi) model, the S2721QS, which costs $374.99.  Pros:

1440p resolutionPortrait and landscape modeIntegrated speakers

Cons:

Low 75Hz refresh rateNo USB-C ports

HP has embraced USB-C for its new range of ‘Advanced Docking’ monitors. Admittedly, the E27d is fairly expensive at $534 for a display with 2560-by-1440 resolution (108.8dpi), but its impressive connectivity features will ensure that it earns its keep – especially when you’re working at home on a laptop.  There are HDMI, DisplayPort and USB-C connectors for video input, with a built-in KVM switch (keyboard/video/mouse) that allows you to connect two computers to the display and share the same keyboard and mouse. Using the USB-C input allows you to charge your laptop via the monitor and also provides access to the monitor’s integrated USB hub, which provides four USB 3.0 ports for connecting your office accessories, along with an additional USB-C port for devices, such as hard drives, that may require power over USB-C. There’s even a built-in 1080p IR-equipped webcam with a privacy slider that you can use for video calls or just to log into your PC using Windows Hello. If you want a more in-depth look at the HP E27d G4, you can read our full review.  Pros:

Any 4K display costing less than £500 is good value, but HP’s $419.99 U27 manages to throw in wireless connectivity along with other useful features. The slimline 27-inch display provides attractive image quality with 3840-by-2160 resolution (163.2dpi) and 99% of the sRGB color standard, making it suitable for graphics and photo editing and word processing web browsing. It also includes an anti-glare coating and a ’low-blue’ mode to reduce eyestrain.  There are HDMI and DisplayPort interfaces for wired video input, along with a set of internal speakers and a three-port USB hub. It’s a little disappointing that there’s no USB-C as well, but the key feature of the U27 is, of course, that wireless option. If you’ve got a PC running Windows 10, then you can just hit ‘Windows-Key + K’ to pair with the monitor over Wi-Fi, making it easy to get a bigger picture from your laptop at home quickly or to get set up for a presentation in the office quickly. Pros:

4K resolutionGreat color volumeWireless connectivity

Cons:

No USB-C portsOnly one HDMI port

Affordable monitors tend to max out at 27-inches, with larger displays being a luxury enjoyed by well-heeled business executives. However, Philips’ 346B1C provides an imposing 34-inch, ultra-wide curved display for a very competitive price of just under $600 (£640). It does have to compromise a little - rather than providing true 4K resolution, it’s actually closer to 3.5K (3440x1440), but that still provides plenty of room to juggle multiple apps and documents on-screen all at the same time. The extra-wide 21:9 aspect ratio helps, too, while the curved screen lets you really immerse yourself in the task at hand. That’s the only real compromise, though. The 346B1C includes a wide range of additional useful features, including two HDMI ports, DisplayPort and USB-C that will allow you to connect two computers simultaneously and also charge your laptop too. There’s a KVM switch that lets you share your keyboard and mouse with two computers’ built-in stereo speakers, and the USB-C connectivity allows the 346B1C to include a handy hub with four USB ports for your office accessories and an Ethernet port for a lag-free wired network. Pros:

 Ultra-wide 34" screen HDMI, DisplayPort and USB-C input Built-in USB hub competitive price

 Cons:

Not quite 4K resolutionNo webcam

Priced at just $459.99, the Philips 279P1 provides a 27-inch display with full 4K resolution (3840 x 2160, 163.2dpi). It supports 122% of the sRGB color standard, making it suitable for graphics, presentations and photo-editing work, as well as general office productivity software. The stand also allows you to adjust height, tilt and swivel, and even to rotate the screen into the upright (portrait) position.  The 279P1 includes two HDMI ports, DisplayPort and USB-C for video input. The USB-C port makes it ideal for working from home with your laptop, as it can charge the device; it also allows you to use the built-in USB hub that includes four additional USB ports and RJ-45 Ethernet for a wired network connection. Pros:

4K resolutionExcellent color volumeUSB-C charging and video output

Cons:

No VRR support
