3M Bright Screen Privacy Filter vs Kensington MagPro Magnetic Privacy Screen
Which should you buy? Our verdict on both, pulled from our full The Best Monitor Privacy Screens: 4 Compared (and One to Skip) comparison.
The 3M Bright Screen gives up the least brightness and colour accuracy of anything here, which is the tradeoff most buyers underestimate before they fit their first filter. The Kensington MagPro takes a small step back on image quality and repays it with a magnetic mount that makes the filter genuinely practical to remove.
3M Bright Screen Privacy Filter
Buy itA brighter louver filter, with the same 30 degree cutoff and far less of the murk.
- Keeps the standard 30 degree each-side cutoff while 3M markets it as brighter than its standard black filters
- Reversible glossy and matte faces in a thin, low-profile panel
- 3M says it reduces blue light without visibly warming the display's colour balance
- COMPLY adhesive strips and slide-mount tabs give a secure, low-profile fit
- Premium price tier, and you only get the benefit if you notice the brightness difference
- Attachment is designed to be installed once, so it is awkward to remove and refit daily
- Check that the Bright Screen range includes your exact monitor size and aspect ratio
Kensington MagPro Magnetic Privacy Screen
Buy itA magnetic frame turns the filter into something you actually take off, which is why it stays in use.

- Reversible matte and glossy faces, and it doubles as scratch protection for the panel
- Ships with a cleaning cloth and a protective storage sleeve

- The bezel-mounted magnetic frame leaves a visible thin border, most noticeable on edge to edge panels
- Individual size codes are rotated in and out, so confirm your exact size is still stocked
