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 itThe brightest louver filter you can buy, with the same 30 degree cutoff and far less of the murk.
- Keeps a 60 degree total viewing cone (30 degrees each side) while transmitting far more light than standard black filters
- Rated by the manufacturer's own lab testing as up to 25 percent brighter than its standard black privacy filter
- Reversible glossy and matte faces, and at 0.29 mm one of the thinnest filters available
- Reduces blue light without visibly warming the display's colour balance
- 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
- Monitor size coverage in the Bright Screen range is narrower than 3M's standard black line
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 storage sleeve
- 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
