PRODUCT DESCRIPTION
Lenovo 14-inch Bright Screen Privacy Filter for X1 Carbon Gen 9 from 3M (4XJ1M77973) - 1 Year Warranty, Singapore Local Warranty
Privacy Without a Dim Screen
The Lenovo 14-inch Bright Screen Privacy Filter for X1 Carbon Gen 9 from 3M keeps on-screen work private from people beside you while staying bright for you. Lenovo rates it at about 85% light transmission, roughly 25% brighter on average than standard 3M black privacy filters.
3M Nanolouvre Technology
Built by 3M with proprietary nanolouvre technology, the filter blacks out the screen for anyone viewing from outside the narrow central viewing zone, making it well suited to open-plan offices, trains, flights and cafés.
Made for the ThinkPad X1 Carbon Gen 9
This is a model-specific 14-inch filter sized for the ThinkPad X1 Carbon Gen 9 16:10 display, so it covers the screen neatly instead of being trimmed from a generic sheet.
Easier on the Eyes
Lenovo states that its Bright Screen filters from 3M block 35% of harmful blue light, a useful extra for long working sessions.

Compatibility & Fit
Which Laptop It Fits
Lenovo names this filter for the ThinkPad X1 Carbon Gen 9; it is sized for a 14-inch 16:10 display. Lenovo UK also lists this part against a number of other 14-inch 16:10 ThinkPad and ThinkBook models (for example X1 Carbon Gen 10 to Gen 12 and T14/T14s Gen 3 to Gen 5); because cut sizes can differ between generations, please confirm your exact model in Lenovo SmartFind before ordering.
16:10 vs 16:9 Matters
Privacy filters are cut to both the diagonal and the shape of the screen. A 14-inch 16:10 filter is taller than a 16:9 filter of the same diagonal, so it will not sit correctly on a 16:9 laptop, and vice versa. Always match size and aspect ratio.
Check Before You Buy
Lenovo provides the SmartFind accessory checker. Enter your laptop's machine type (found on the label underneath the notebook) to confirm compatibility before ordering.

Frequently Asked Questions — Lenovo 14-inch Bright Screen Privacy Filter for X1 Carbon Gen 9 from 3M
Which laptop does this filter fit?
It is designed for the ThinkPad X1 Carbon Gen 9 (14-inch, 16:10). For any other model, confirm in Lenovo SmartFind first.
Will the screen look much darker?
Less than with a standard black filter. Lenovo rates it at 85% light transmission, about 25% brighter on average than standard 3M black privacy filters.
How wide is the private viewing zone?
Lenovo lists a 60° viewing angle, so the screen is clear from straight ahead and goes dark for viewers more than about 30° to either side.
Can I use a 16:9 filter on my 16:10 laptop instead?
No. A filter for the wrong aspect ratio will leave gaps or overhang. Choose the filter made for your model.
What warranty applies?
Lenovo lists a 1-year warranty, and every SourceIT purchase includes Singapore local warranty support with a GST invoice.
