Lenovo ThinkVision LT1421: An In-Depth Review

When it comes to travelling and working on-the-go, nothing can beat the functionality and convenience of a laptop. Sure tablets and fablets/phablet (phone tablet) offer more convenience, as they are easier to carry around, slip inside our bag, and pull anytime we want, but these devices can’t be trusted in getting work done while on the go. This is the reason why most business travelers still can’t let go of their trusted portable computers. As a matter of fact, many laptop users even find their laptop screen insufficient, especially in working with a couple or more applications, opening multiple windows and document files, spreadsheets or giving presentations in a small group of people. Enter Lenovo ThinkVision LT1421a USB powered 14-inch portable display that will extend your laptop’s real estate for a dual monitor laptop setup.

Who is it for?

The Lenovo ThinkVision LT1421 is designed for road warriors who usually find that their notebooks and laptops isn’t enough for their computing needs. This portable monitor provides an extra screen real estate that could help laptop users do more in less time, while travelling.



Excellent Travel Companion for Users Who Need Extra Screen Real Estate 

Link most ThinkVision monitors, the Lenovo LT1421 is designed to be paired with the ThinkPad notebook series. The 14-inch TN+ panel shows images at 1366 x 768 resolution, and is coated with a matte finish to keep glares and reflection at minimum. It’s quite a neat-looking display, and despite of few limitations, the display provides good color quality and text performance.

Thin and Lightweight Display, Great Solution for Travelers and People On-The-Go

With the Lenovo LT1421, you have the luxury to use your laptop in a dual monitor setup. Weighing just a little over 2 lbs., this portable monitor is easy and very convenient to carry around and use anytime, anywhere. Its slender body and outstanding image quality makes it a perfect choice for travelers.

It also comes with a protective cover that doubles as a stand or support base, great for keeping the screen safe while traveling.

Great Color Quality and Small Text Reproduction for General Use

Despite the 200c/m2 maximum brightness capacity, this Lenovo monitor scores fairly in DisplayMate Color Scale test; colors appear well-saturated and uniform, though it’s not as punchy compared to its glossy counterparts. It’s also supported by an excellent backlighting that doesn’t show color bleeding whatsoever.

The panel does a good job in displaying dark shades of gray, but not quite well in white shades of gray, as the last two shades seem whitewashed in 64-Step Grayscale test.

One of the biggest strengths of this display however, lies on its great small text reproduction, as fonts look crisp, clear and well-defined even at 5.3 points.

However, this monitor may not be a perfect solution for entertainment, particularly for watching color-critical movies, as it’s only capable of displaying 262K colors, quite far from16.2 million that most 6-bit panels have today.


Decent Viewing Angle

Off-angle performance of this Lenovo display looks decent, but things on screen look dull if you go beyond 70° from the center of the screen. This is usually the weakness of TN panels. The screen darkens when viewed from bottom and top, but still make colors look identifiable.


Design and Features

If you like the ThinkPad’s business-like aesthetic, then you will surely love the look of Lenovo LT1421. This 14-inch TN+ panel is housed in an attractive and extremely thin (0.4 inch bezel in top and sides) matte black plastic casing. The cabinet is scratch-resistant and provides good grip, though it’s not as soft to touch as the ThinkPad X220 laptop.

The bottom part of the bezel is 1.1 inch thick, with silver Lenovo logo at the center. There’s a ThinkVision badge placed on the upper bezel. It is equipped with a matching black plastic cover that easily snaps into place to cover and protect the monitor’s screen while travelling. It can also be used as a stand for the monitor. This device also comes with a brightness rocker and a bendable arm that lets you position and adjust the angle of your display.


Light and Slim to Fit Inside Your Bag and Use Anywhere, Anytime

Weighing only 2.4 lbs. (with cover attached), the Lenovo ThinkVision LT1421 is a light and slim USB monitor that you can conveniently slide and fit in your large messenger bag.


Sturdy Cover that Doubles as Stand for Secure Transit and Comfortable Use

As said above, this Lenovo portable monitor comes with a detachable cover. The cover works by snapping to the front of the monitor and protect its screen from marks and scratches while it’s inside your bag.

When the detached, users can place the display on top of the cover and use it as a base for better ergonomics (though the display can stand up just fine when placed on to a flat surface), though it’s not a requirement. Usually, you will just need one USB connector to power up the screen, but certainly applications may require drawing power from the laptop from both USB ports.


USB Connectivity

The monitor gets its power from the host PC and does not need a bulky power brick. The only thing you will need to bring with when planning to use this portable monitor on your next trip is its USB cable. LT1421 is completely bus-powered, and it comes with a Y cable that has a single microUSB port in one end and two full-size USB plugs on the other end to attach to your laptop.


Controls and Adjustments

Along with the USB port are some controls for the LT1421, including the single rocker switch that toggles 16 brightness levels, a cable lock slot, and an arm stand for picture frame-style which lets you tilt your display as far as 40° back. Unlike your typical LCD monitor, this portable Lenovo monitor doesn’t come with any picture settings like Contrast and Color Controls.


Easy Setup

The Lenovo LT1421 is easy to setup and use. All you have to do is install the drivers and DisplayLink software to your computer and monitor will do the rest once you plug in its USB cable. If your laptop doesn’t come with an optical drive, then simply download the software from Lenovo’s website. Mac users also have dedicated DisplayLink downloadable software available from the site.

When the screen powers up, you can right click the DisplayLink icon from the system tray and set the orientation and resolution for your screen. From here, you can also choose the setup you want for your extra monitor, either have it as a duplicate or as an extension from your laptop’s display. Launch the pop-up menu by pressing the Windows key and P button simultaneously for quick setup and choose between duplicate, extend, computer monitor only and projector (in this case, the Lenovo LT1421 extra monitor) only.

Bottom Line

(image from Amazon)

If you fancy having an extra monitor you can bring with you as you travel to improve productivity or for your presentation needs, then the Lenovo LT1421 can be a good choice for you. It is thin, compact, and very light to fit inside your messenger bag and carry around. Build quality is great, and it comes with a cover that will protect its screen from risks of scratches as you keep it inside your bag, while single USB port requirement and DisplayLink feature makes it very convenient to pull out from your bag and use anytime, anywhere. Performance wise, it has a lot to offer to laptop users and travelers; colors are surprisingly bright, with good color and text quality.

This monitor is designed to work as a secondary screen on the road. Thus, it’s hard to expect too much, as it’s simply not made for great performance. If there’s something we can complain about, it will be the lack of picture settings and weak light grayscale performance. Other than that, the Lenovo ThinkVision LT1421 makes a great travel companion for computer users requiring extra display while on the road, not to mention it comes with an affordable price tag.
