Best large monitor in 2021 | ZDNet

Large monitors with a size of up to 49 inches can reduce desktop clutter and improve the efficiency of knowledge workers and creative users.



| Topic:

In many offices, it is common to see employees sitting side by side on their desks with two monitors. This is useful for keeping financial information updated. For example, financial information is often displayed on one screen in real time, while the second display is used to perform more routine tasks, such as email and word processing. Creative users usually like to view full-size video and graphic files on dedicated displays, while their editing applications and other tools are available nearby. Some people only need two monitors for two computers at the same time, perhaps using a laptop and a desktop PC side by side. 

But when you can only have one monitor, why put two monitors on the table? The latest trend in business monitors is "multitasking" monitors-large displays can provide enough space to accommodate multiple applications or multiple windows on the screen at the same time. These multi-function displays may also include other features, such as the ability to create a picture-in-picture (PiP) effect, where you can focus on the main application displayed in a larger window, while maintaining it in a smaller auxiliary window Pay attention to information such as stock prices or emails. Some modern monitors also provide a split screen effect (also known as picture-by-picture (PbP)), allowing two computers to share a screen.

Functions such as this work best on larger displays, and the new generation of multitasking monitors usually start at 32 inches and go to 49 inches. Even so, these large monitors still take up much less space than a pair of 27-inch screens sitting on a desk (especially if you are working temporarily at home, there have been many such monitors last year) ).  

This is a guide to some of the best multitasking monitors for advanced knowledge workers and creative users.

 A series of ultra-wide curved displays are partly aimed at gamers and video enthusiasts, but also include features such as picture-in-picture (PiP) and picture-in-picture (PbP), which allow knowledge workers and advanced users to combine two computers And view the images in both at the same time. The ultra-wide 21:9 aspect ratio is also very suitable for viewing multiple documents and windows.

For video connections, there are two HDMI inputs and DisplayPort inputs and outputs, and two USB 3.0 ports for peripherals. However, it is worth noting that XR382CQK is not a true 4K display, because its unconventional 21:9 aspect ratio has a resolution of 3840 x 1600 (110.9ppi) instead of the standard 16:9 3840 x 2160. In Acer's support forum, it is recommended that Macs dislike the aspect ratio for some reason.

 It is good value for business users who want a large, multi-function display (especially if you work from home and have to pay for it yourself). This 31.5-inch monitor offers 4K resolution (3840 x 2160, 139.9ppi), which is well under $500, and has useful features for multitasking with multiple applications or two connected computers. 

The monitor provides HDMI and DisplayPort interfaces, as well as DVI and VGA for older PCs and laptops. There is also a built-in USB hub with two USB 3.0 and two USB 2.0 ports, although unfortunately there is no USB-C support.

You can move the second "subsource" image on the screen, change its size, and even switch the audio of the monitor's built-in speakers between different computers. You can also rotate the screen to an upright (portrait) position.

Screens larger than 27 inches used to be a luxury-for financial executives, for example, it was a status symbol. However, extensive remote work has changed all of this, and increased demand for larger displays has also helped lower prices. Dell's new product 

 It is one of the most affordable 31.5-inch monitors we have seen so far.

 In January, the newest member of Dell's UltraSharp family of products is an impressive all-round product that will be suitable for a variety of applications.  


 Not the largest display in the series, but its 37.5 inch screen can provide close to 4K resolution (3840 x 1600, 110.9ppi) and 21:9 widescreen aspect ratio, which is very suitable for processing multiple applications and windows on the screen at once. It supports 100% sRGB color standard, so it will be suitable for various graphics and design applications. It also supports 95% of the DCI-P3 standard for video editing. Although it lacks the true 4K resolution required by broadcast professionals, the UltraSharp 38 U3821DW is still sufficient for editing presentations and streaming content videos. 

It also connects well, with two HDMI ports DisplayPort and USB-C, and a four-port USB hub with a KVM switch, allowing you to connect two computers and share a keyboard and mouse. There is even an RJ-45 Ethernet port to connect your PC or laptop to a wired network.

HP's F-series monitors have always focused on value for money and fashion 

 Managed to provide an attractive 34-inch curved display for less than $500. 

Low cost does bring some compromises: 34f is closer to 3K resolution than true 4K, but its 3,440 x 1,440 pixels (109.7dpi) and widescreen 21:9 aspect ratio still provide enough space to run multiple applications in parallel Procedure-side. It also provides a "low blue light" mode and anti-glare coating to reduce eye fatigue. There are two HDMI ports and a DisplayPort, allowing you to connect multiple devices, and a pair of USB 3.0 ports for connecting a keyboard, mouse or other peripherals. Unfortunately, there is no audio support, so you have to rely on the built-in speakers of your PC or provide a set of external speakers yourself. 

This model also does not include USB-C, although it is expected that new models with similar prices will soon add USB-C and some additional USB 3.0 ports.

HP introduced several new displays at CES in January, with a focus on "ultra-wide" displays, which provide plenty of room for multitasking through multiple applications and even multiple devices. 

 It also has an attractive price, offering a 43.4-inch curved display for less than $1,000. It is not completely 4K, but its 3840 x 1200 resolution (92.7ppi) provides a widescreen 32:10 aspect ratio, which can accommodate multiple browser windows, emails, and some very large spreadsheets. If you need to do some photo editing or presentation work, it also supports 99% sRGB color standard. 

There are HDMI, DisplayPort and USB-C inputs for connecting computers and other devices. The USB-C port can charge the laptop, but the S430c also provides a four-port USB hub and another USB-C port for charging other devices. The monitor provides a split screen mode, so you can connect and view two devices at the same time-and even includes a feature called HP Device Bridge (see HP’s 

 (For more information), allows you to drag and drop files between two Windows, Mac, Android or Ubuntu devices. Coupled with the pop-up 1080p infrared webcam, you will get multitasking capabilities.

We like it very much 

 We reviewed it in 2019, but this model is quite expensive for a 32-inch display (and it seems not currently available in the US). Newer 

 Provides a cheaper alternative to office work at a very competitive price of US$538. 

The 346B1C can be upgraded to a larger 34-inch display, although the low price means it cannot provide true 4K resolution. Even so, 3440 x 1440 resolution (109.7dpi) and widescreen 21:9 aspect ratio still provide enough space for running multiple applications in parallel. It also has a 100Hz refresh rate, anti-glare coating and low blue light mode, which can reduce eye fatigue during work. The monitor supports 119% of the sRGB color standard and 90% of Adobe RGB, so it is very suitable for graphic work and photo editing. 

The 346B1C's USB-C, HDMI and DisplayPort for video input, as well as a three-port USB hub and KVM switch, can also be well connected, allowing you to connect two computers and share a keyboard and mouse.

Philips makes many curved displays designed for games and videos, but its top products 

 Mainly aimed at the B2B sector-especially financial institutions such as banks and trading floors, where multi-display settings are very common. 

The curved design is designed to occupy your entire field of vision, providing "best visual comfort" by eliminating interference, allowing you to immerse yourself in the world of data. The 48.8-inch display offers a resolution of 5120 x 1,440 (109ppi) and has the same ultra-wide 32:9 aspect ratio as a similar 49-inch display (unfortunately, this can be troublesome for Mac users). However, just like Philips' moderately sized "dock monitor" series, the 499P9H is equipped with useful connectivity features, including two HDMI ports and a DisplayPort, as well as a USB-C port that can handle data, video, and laptop charging. 

There is also a built-in KVM switch that allows you to control two computers with a mouse and keyboard, and the "multi-view" function provides a split screen option to view two computers on the screen at the same time. Philips 499P9H even has a webcam for video conferencing and Gigabit Ethernet for connecting to wired networks.

Samsung's latest M7 series display 

, Very suitable for multitasking, very suitable for home work and entertainment. Described as "full-screen display" M7 provides a 32-inch display with a resolution of 4K (3840 x 2160, 137.7dpi), which is very suitable for running various office and productivity software. Samsung did not mention the level of support for Adobe RGB or sRGB color standards, so the 32M70A is not the best choice for professional-level graphics or video works, but when this multifunctional display is only $349.99, it is hard to complain. 

The 32M70A also performs well in other areas, with impressive connectivity features, including two HDMI ports and a USB-C port. Built-in wi-fi (802.11ac, Wi-Fi 5) allows M7 to act as a remote terminal for editing MS Office documents stored in the cloud, and it also supports Bluetooth 4.2. When you finish your work, the 32M70A includes Samsung's Smart Hub, which can effectively turn it into a smart TV to stream Netflix, HBO and other video services. By supporting Apple's AirPlay, the multi-faceted display can also stream audio and video from Apple devices.
