The M14 comes with a meter-long USB Type-C cable. You can connect to a laptop using either the right or left USB-C port on the panel, depending on which side of the laptop you want the display to be placed. The USB-C ports support DisplayPort over USB-C, as well as USB PD (power delivery). Those two buttons are the extent of the M14's onscreen display (OSD) controls. The HP EliteDisplay S14 has a wider selection of OSD controls, with four buttons letting you change settings such as brightness, contrast, and color mode. (Selections for the latter include Low Blue Light, Night, Reading, HP Enhance+, Multimedia, and Photo.) That said, I didn't find myself fretting over the limited controls when testing the M14. With its long USB-C cable, I wish there was some form of cable management. You won’t be able to tweak its display much beyond brightness or use different display profiles, like you can with the Asus ZenScreen MB16AC, and, unlike the larger and barely heavier Viotek LinQ P16C, there are no speakers. Plus, if you plan to take this on the go often, as is intended, you’ll almost certainly want to buy a replacement carrying case to replace the flimsy one Lenovo includes. Also, the display only works with USB-C (DisplayPort 1.2 over Alt mode); there’s no DisplayLink tech, so some laptops won’t support it. One really impressive thing about the ThinkVision M14t, which we also saw in the original M14, is its color-gamut coverage, which is unusually good for a portable monitor. Lenovo states that the M14t covers 72 percent of the NTSC color space, a gamut designed for analog TV that is still often used as a point of comparison: 72 percent NTSC is approximately 100 percent of the sRGB space. In my testing, the M14t covered 97.9 percent of the sRGB space, a tad more than the M14’s 97 percent.

In addition to our formal testing, I viewed a selection of film clips and photos using both a 16:9-aspect-ratio Lenovo ThinkPad T490 (using the monitor's Original AR setting) and a 16:10 HP Pavilion Aero 13. In both cases, videos were bright, with well-saturated colors, and showing very good contrast in both light and dark areas. Photos also looked bright, with natural-looking colors and excellent contrast. Buying an impressive computer displays doesn’t have to be complicated or expensive. Browse our inventory of options based on group, activity, connections, resolution, aspect ratio, and more to find the best fit for your lifestyle. With the right monitor complementing your PC, you can fully realize its potential as a business, gaming, or everyday machine. The Lenovo also did a better job at color production than the Asus in all three color gamuts we tested for: sRGB, Adobe RGB and DCI-P3. The biggest difference was in the sRGB color gamut, where the Lenovo hit 98% coverage and the Asus only reached about two-thirds of that (66.4%).

VGA is a more dated method of connecting your PC and visuals but there are still plenty of PCs around that may require this input method. The ThinkVision M14t can only connect to a computer that outputs via USB-C’s alt mode, specifically using DisplayPort over USB-C. Modern generation Lenovo ThinkPads can all do this as can laptops from many other vendors, but if you don’t have this capability, don’t buy this monitor. Scale new heights of productivity, flexibility, and style with a touch-enabled mobile monitor. The slim and light ThinkVision M14t is a 14-inch Full-HD display that provides you with an extra screen whenever you need it. In the end, the M14 isn’t quite the all-supreme champion that portable monitors have been missing, but it’s definitely the one that comes closest so far. Display quality exceeds expectations, especially for colour accuracy, and the sleek design is both stylish and smart. We have a large selection so you can find the perfect monitor for your needs. And no matter what screen size or image quality you prefer – or even where you intend to use it – Lenovo has all the most popular display sizes, and resolutions. Even if you are on the go Lenovo has portable monitors that attach to your laptop or plug into your laptop and give you a second screen to keep your productivity up.

As mentioned, there are two USB-C ports, on each side, and Lenovo advertises this as a way to make it easier to display the monitor to the left or right of your laptop. However, with the included 1m-long USB-C cable, you could probably achieve the same effect even without two USB-C ports. Including an HDMI port instead would have added more versatility by allowing the monitor to easily connect to more device types, like a TV or Raspberry Pi. But with USB-C you can connect the monitor to a tablet or smartphone too. As monitor technology has evolved over the years, so have the types of inputs you’ll potentially use to connect your monitor to your PC and other devices. The most common way to connect your PC to your preferred display is by HDMI, but most modern monitors feature either HDMI or USB Type-C input options to be easily compatible with today’s tech. Still, this is brighter than most portable monitors. Their measured brightness tends to cluster in the 180-to-200-nit range. Exceptions are the ThinkVision M14 (280 nits), the ViewSonic VG1655 (245 nits), and the ViewSonic TD1655 (219 nits). The compact, lightweight Lenovo ThinkVision M14 is a winning choice as a mobile monitor for business or personal use. It is well equipped to provide you with a second screen while traveling, and bright and glare-free enough for passable viewing in a variety of challenging lighting environments. This USB-C-only display can be powered from your laptop over the same cable from which it's receiving data or video; additionally, its "power pass-through" design lets you run the M14 and charge your laptop with a single AC adapter. The monitor's advertised contrast ratio is 1,500:1; I measured it at 1,231:1, which is obviously less but still among the best we've seen from a mobile display. Most competitors have contrast ratios somewhere between 700:1 and 1,000:1.Home monitors need to be versatile enough for a wide range of activities. When watching Netflix, you’ll want a widescreen monitor with powerful color quality and crisp resolution. When surfing the web at different times of day, the display should have adjustable brightness controls that match your lighting conditions. With a 14-inch screen, the M14 is smaller and lighter than the Asus ZenScreen MB16AC, which has a 15.6-inch display, measures 14.2 x 8.9 x 0.3 inches and weighs 1.7 pounds. But you can still get a larger screen without adding too much weight. The 15.6-inch Viotek LinQ P16C is just barely heavier than the Lenovo (1.4 pounds versus 1.3 pounds) than the Lenovo, despite being 16 inches and having speakers. Be sure to research and consider the type of input option that will best connect with your PC and support your usage habits before you buy. The ThinkVision M14t comes with a USB Type-C cable, as well as an L-shaped USB-C-to-USB-C connector. You can connect to a laptop using either the right or left USB-C port on the panel, depending on which side of the laptop you want the display to be placed. You can even connect to an Android smartphone, provided that it has a USB Type-C port. The USB-C ports support DisplayPort over USB-C, as well as USB PD (power delivery).

You can connect the M14d to a laptop using either the right- or left-side USB-C port, depending on which side of the laptop you want to put the display. You can even connect to an Android smartphone if it has a USB-C port. The ports support both DisplayPort over USB Alternate Mode and USB power delivery, letting you power or charge a laptop connected to the monitor with the latter plugged into a wall outlet.Best of all, the ThinkVision M14t’s color accuracy is right up there with that of the ThinkVision M14. It's considerably better than what we have tested on any other general-purpose mobile monitor. A note also for those who might want to use a portable monitor at home with their desktops when they aren’t traveling: Most desktops or motherboards with USB-C ports do not support alt mode (unless you happen to have a board with Thunderbolt ports). But, if you have a recent Nvidia graphics card with a USB-C VirtualLink port, that port does support alt mode. So you should be able to plug this monitor into your graphics card’s USB-C port for desktop connectivity. Just note that VirtualLink doesn’t make an appearance on Nvidia’s latest 30-series cards.
