12.3 inch 3:2 privacy filter

The 3M BP123C3E is a Bright Screen Privacy Filter designed for 12.3 inch laptop displays with a 3:2 aspect ratio. It limits the viewing angle so that on-screen data is visible only to the person directly in front of the screen. The filter is supplied new and carries UPC 051144065332.

For users who need visual privacy on a 12.3 inch

This accessory suits professionals who work in shared or public spaces and want to prevent side-angle viewing of confidential information. It is not intended for screens with different dimensions or aspect ratios, nor for users who do not require a privacy layer.

12.3 inch 3:2 screen compatibility

The decisive specification is the exact match between the filter and a 12.3 inch display with a 3:2 aspect ratio. Only panels of that size and shape will align with the filter's viewing-angle restriction and physical dimensions.

Questions about this item

Which screen sizes and aspect ratios does the BP123C3E filter cover?

The filter is made for 12.3-inch displays with a 3:2 aspect ratio.

What physical clearance does the BP123C3E need around the display bezel?

The filter sits flat on the screen surface and requires a clean, smooth bezel area for the adhesive strips or tabs to bond.

How is the BP123C3E attached, and what step do people often miss?

Clean the screen thoroughly, align the filter, then press the adhesive strips firmly; skipping the cleaning step causes dust bubbles and poor adhesion.
