Sized for Lenovo ThinkBook Plus Gen 3
This filter is made specifically for the Lenovo ThinkBook Plus Gen 3, whose 17.3-inch display uses a 21:10 ultrawide aspect ratio. A model-specific cut follows the screen's exact dimensions, so it covers the panel neatly without trimming.
For Work on the Move
A simple, effective way to protect sensitive information when working on trains, flights, in cafés, at client sites and in open-plan offices.

Compatibility & Fit
Which Laptop It Fits
This filter is made specifically for the Lenovo ThinkBook Plus Gen 3, whose 17.3-inch display uses a 21:10 ultrawide aspect ratio. A model-specific cut follows the screen's exact dimensions, so it covers the panel neatly without trimming.
Main 17.3-inch Screen
The ThinkBook Plus Gen 3 has a 17.3-inch 21:10 main display and a separate 8-inch secondary display. This filter is sized for the 17.3-inch main screen.
Aspect Ratio Matters
Privacy filters are cut to both diagonal and shape. 16:9, 16:10, 3:2 and 21:10 screens of similar diagonal have different heights and widths, so a filter for one will not fit another correctly. Match both the size and the aspect ratio; this part is 21:10.
Check Before You Buy
Use Lenovo SmartFind to confirm compatibility with your machine type (printed on the label underneath the laptop).
