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 up to 25 percent brighter than other black privacy 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 Flip Attach and COMPLY adhesive strips give a secure, low-profile fit
- Premium price tier, and you only get the benefit if you notice the brightness difference
- The COMPLY Flip Attach swings the filter up for screen sharing, but the mount is designed to stay on, so it is awkward to remove and refit daily
- The Bright Screen sizes listed on 3m.com are laptop and tablet cuts, so check your exact size and aspect ratio before buying for a monitor

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.
- Magnetic strip frame lets the filter snap on and lift off in seconds with no residue
- Published viewing angle of plus or minus 30 degrees, so the privacy claim is verifiable
- Reversible matte and glossy faces, and it doubles as scratch protection for the panel
- Ships with a cleaning cloth and a protective case
- Blue light reduction rated up to 52 percent, which warms the picture more than the 3M filter does
- 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
