The Lenovo ZenBook Duo. Cramming a second display onto a laptop has been challenging for makers like Asus, HP, and even Apple. However, we think Lenovo is closest to nailing the concept for a more seamless user experience.
The Lenovo ThinkBook Plus Gen 3 directly succeeds last year’s ThinkBook Plus Gen 2. Though you can’t tell from the name alone, the Gen 3 model is a significant change from its predecessor in more ways than most other laptops. While the Gen 2 model is a 16: 10 13.3-inch convertible with a secondary 12-inch E-Ink touchscreen, the Gen 3 model is a 21: 10 17.3-inch clamshell with a secondary 8-inch IPS touchscreen. The two models are so different that arguments could be made about the naming of the Gen 3 model in relation to Gen 2 as they both serve very different purposes.
Our Gen 3 review configuration includes the 12th gen Core i7-12700H CPU with 16 GB of soldered RAM and 512 GB PCIe4 storage for approximately $1600 USD. A Core i5-12500H SKU is available, but all options come with the exact same primary 3072 x 1440 matte IPS touchscreen, secondary 8-inch 800 x 1280 IPS touchscreen, and integrated Iris Xe graphics.
Alternatives to the ThinkBook Plus Gen 3 include the 15-inch Asus ZenBook Pro Duo series and other 17-inch laptops designed for content creators or office productivity like the LG Gram 17 or Dell XPS 17.

The chassis shares the same aluminum alloy materials as on other ThinkBook models like on the recent ThinkBook 16 G4 Plus. Thus, if you’ve held a ThinkBook model in the past, then the smooth dark gray surfaces of the ThinkBook Plus Gen 3 will feel instantly familiar. The design targets casual offices and SMB environments in between the consumer-centric Yoga and more traditional ThinkPad models.
Build quality is slightly below that of a Yoga or ThinkPad X series model. The lid and base are a bit more susceptible to twisting and creaking likely due to the larger 17.3-inch form factor and relatively thin skeleton. Alternatives like the smaller ZenBook Duo or heavier XPS 17 feel firmer and with a more solid feel especially in regards to their hinges.
The elongated aspect ratio has resulted in a chassis that’s both wider but shorter than other 17-inch laptops. It’s thankfully still thin and lightweight when considering its size category. The XPS 17, for example, is half a kilogram heavier.
It would be a crime if the Gen 3 model came with fewer ports than the much smaller last generation model. The system integrates two USB-C ports much like its predecessor plus new USB-A and HDMI ports along the rear for a wider variety of options. Note that only one of the two USB-C ports is compatible with Thunderbolt, but either can be used for charging or DisplayPort.
There is no SD card reader which is a little disappointing considering the large form factor and focus on office/editing tasks.
An Intel AX211 comes standard for Wi-Fi 6E and Bluetooth 5.2 connectivity. We experienced stable transfer rates when paired to our 6 GHz network.

The 2 MP camera is sharper than the ones on the XPS series but still not as good as the 5 MP cameras on many newer HP models. Both an IR sensor and shutter are present for Hello support and privacy, respectively.
The bottom panel is secured by nine T5 Torx screws. We recommend removing the pen from the rear first and then using that opening to more easily detach the panel from the base.
There is not much to upgrade once inside as both the WLAN and RAM modules are soldered.
The system integrates an active stylus much like on last year’s Gen 2 model. The standard one-year limited manufacturer warranty applies if purchased in the US.
The typing experience remains identical to other ThinkBook laptops including the ThinkBook 14 G4 despite the inclusion of the secondary touchscreen. The wider footprint allows for a relatively spacious clickpad, touchscreen, and keyboard all on one laptop whereas they can feel cramped on a smaller 14-inch or 15-inch ZenBook.
Key feedback is shallow and light not unlike the keyboards on many Yoga, IdeaPad, or midrange Ultrabook models. ThinkPad keyboards are generally firmer and with deeper travel in comparison.
The clickpad is of a decent size unlike the tiny one on the ZenBook Duo UX481 (12 x 7.5 cm vs. 5.5 x 7 cm). Gliding is smooth and responsive due in part to the faster 120 Hz native refresh rate of the main display. Clicking on the clickpad is firm and with a loud auditory click for satisfying feedback.
The main IPS display may be of an atypical aspect ratio, but it carries the same characteristics as most other high-end IPS panels. The ~1000:1 contrast ratio, reasonably fast black-white response times, fast 120 Hz native refresh rate, and >95 percent P3 color coverage all make the display surprisingly good for both graphics, editing, and everything in between. Both colors and response times in particular are deeper and faster, respectively, than the panel on the ThinkBook Plus Gen 2 while maximum brightness remains about the same.
