One of the biggest trends coming out of this year’s CES wasn’t something people will necessarily notice at first glance unless they look closely. After enduring years of cramped, “widescreen” laptop displays, it looks like we’re finally starting to say goodbye to the 16:9 aspect ratio.
An aspect ratio is the ratio of a display’s width to a display’s height (in that order). For example, a screen with a resolution of 500 x 500 would have an aspect ratio of 1:1. Think of it like simplifying a fraction: a 1080p screen has a resolution of 1920 x 1080, which divides down to 16:9.
The aspect ratios you’ll typically see on laptops are 16:9, 3:2, 16:10 (which, for whatever reason, is called 16:10 rather than 8:5), and (occasionally) 4:3. 16:9 is the most common option and also the one with the lowest amount of vertical space relative to its horizontal space.
If you have a modern Windows laptop, there’s a good chance your screen is 16:9. If you have a gaming laptop, its panel is almost certainly 16:9. (It’s unusual to find high refresh-rate panels with other proportions.) There are some notable exceptions: Microsoft’s Surface products have been 3:2 for quite some time, while Dell’s last few XPS 13 models and Apple’s MacBooks are already 16:10. But traditionally, Windows laptops like these have been few and far between.
16:9 screens are cramped — at least compared to other options. I usually can’t comfortably work in multiple windows side by side without zooming out or doing a ton of vertical scrolling, and when I’m multitasking in Chrome, the tabs get tiny very quickly. If you’re used to using a 16:9 screen and you try a 16:10 or 3:2 display of the same size, you probably won’t want to go back. You just have a lot more room, and it’s a much more efficient use of screen space.
But this CES showed that 16:10 and 3:2 displays are inching closer to the mainstream. These are some of the biggest laptops announced at the show that are offering non-16:9 display options:
That doesn’t mean there are no 16:9 displays left — plenty of laptops still use it, and probably will for the foreseeable future. And some of these devices, like the LG Grams, were 16:10 already.
But it’s significant that a large number of the flagships we’ll be seeing in the first half of 2021 will be either 16:10 or 3:2. In fact, when you include MSI’s 16:10 Summit E13 Flip and Razer’s 16:10 Razer Book 13 (both of which were announced prior to CES), I can’t think of a mainstream consumer laptop company that isn’t now selling a non-16:9 flagship-level machine. It’s clear that companies across the board are moving toward laptops with taller aspect ratios, and I fully expect to see more of them in the years to come.
Again, this may seem like a boring change. But it will make a big difference in the lives of this year’s laptop buyers, particularly people shopping for a work-from-home device. I switched from a 16:9 laptop to a 3:2 Surface Book 2 back in 2017, and it was one of the best purchasing decisions I’ve ever made. If you’re using a 16:9 screen now and are looking to upgrade this year, I encourage you to give one of these new devices a shot. You won’t want to go back.
In order to avoid video images which are stretched, chopped, squeezed, shrunk or distorted, be sure to choose a LCD monitor with a aspect ratio (4:3 or 16:9) that matches your camera or other incoming video signal.
There’s no doubt that today’s HD televisions look fantastic. However, are 16:9 aspect ratio monitors really the best choice for your industrial/commercial project?
Aspect ratio is the relationship of the width of a video image compared to its height. The two most common aspect ratios are 4:3, also known as 1.33:1 or fullscreen, and 16:9, also known as 1.78:1 or widescreen. (Larger aspect ratio formats are used in the motion picture industry.)
All the older TV’s and computer monitors you grew up with had the squarish 4:3 shape-- 33 percent wider than it was high. 4:3 LCD monitors can display analog video signals that conform to NTSC and PAL standards. They are not capable of displaying HD (high-definition) video.
The 4:3 aspect ratio dates back to 1917, when the Society of Motion Picture Engineers adopted it as the standard format for film. In the 1930’s, the television industry adopted the same 4:3 standard. But in the mid-1950’s, the motion picture industry began developing several widescreen formats to improve their decreasing audience numbers. Television broadcasting stayed with the 4:3 standard, until the recent move to HDTV and 16:9 widescreens.
16:9 is the native aspect ratio of most high-definition LCD monitors and TV’s (15:9 and 16:10 are very similar). It is 78 percent wider than it is tall, and fully one-third wider than a 4:3 screen. 16:9 widescreen monitors are ideally suited to display HD video signals. Some models can also display SD (standard definition) video signals, but this will require some compromises, as you will read below.
Nearly all experts agree that in order to display optimal video images, it is critical to match the aspect ratio of the monitor to the aspect ratio of the camera (or other incoming video source). Below is a example of a 16:9 image on a 16:9 monitor:
However, the majority of cameras in the industrial, commercial, security, and law enforcement industries still utilize 4:3 CCD or CMOS imagers. Therefore, to display clear, undistorted video images, it is important to utilize monitors with the same 4:3 aspect ratio to match the cameras. Failure to do so will result in distorted images, as shown below.
Unfortunately, despite the continued widespread use of 4:3 cameras, LCD monitors with a 4:3 aspect ratio are getting harder and harder to find, as many manufacturers have transitioned to the newer 16:9 widescreens. TRU-Vu Monitors still offers a complete line of industrial-grade 4:3 aspect ratio LCD monitors. These range in size from 3.5” to 20” screens, in standard, touch screen, rack mount, sunlight readable, medical-grade, optically bonded and open frame LCD monitor configurations. See www.TRU-VuMonitors.com for more details.
16:9 widescreen LCD monitors are the ideal complement to 16:9 format HD cameras, increasingly used in video conferencing, broadcast and medical applications. They display superb, distortion-free, high-definition images. TRU-Vu Monitors offers these in 21.5” to 46” LCD screen sizes, in standard, touch screen, sunlight readable, medical-grade, optically bonded and open frame configurations.
In conclusion, in order to avoid video images which are stretched, chopped, squeezed, shrunk or distorted, be sure to choose a LCD monitor with a aspect ratio (4:3 or 16:9) that matches your camera or other incoming video signal.
