This category holds privacy filters and screen protectors for laptops, with a few options for tablets and monitors, from brands such as StarTech.com, Lenovo, Dicota and Mobilis. It suits anyone who works with confidential documents in offices, trains or cafés, or who wants less glare and blue light on the screen.
How to choose a laptop privacy filter
Screen size and aspect ratio. Filters are cut to a fixed size, so measure the visible screen diagonal and check the ratio instead of relying on the laptop name alone. Our range runs from 13.3 inch to 16 inch, with 14 inch and 13.3 inch among the most listed sizes. Ratios of 16:10, 16:9 and 3:2 are all available, and a 16:9 filter will not fit a 16:10 screen properly.
Viewing angle. A privacy filter darkens the image when someone looks at it from the side. Many filters in our range limit viewing to 30° either side of centre. A narrow angle gives more privacy, but you need to sit squarely in front of the screen.
Filter features. Some filters only provide privacy, while others add an anti-glare surface for bright offices, an anti-reflective layer or blue light reduction. The blue light figures in our range go up to 51%, with other products at around 25% to 47%. Stronger blue light filtering can slightly shift colours, so keep that in mind for photo or design work.
Fit and attachment. Check how the filter attaches (adhesive, clips or sliders), because that decides whether you can remove it for presentations or when sharing the screen. Most filters in our range are listed as frameless types that sit directly over the display. Touchscreen owners should confirm in the product details that the filter works with touch input.
Device type. Most products in our range are made for laptops. A small number suit tablets, and one is listed for both monitors and laptops, so confirm the device type before you order.

Frequently asked questions
Does a privacy filter make the screen darker?
Yes, a privacy filter reduces screen brightness a little, even when you look straight at it. This is because it blocks light at wider angles. Raising the display brightness usually makes up for it, though battery life may drop slightly.
How do I find the right filter size for my laptop?
Measure the visible screen diagonally in centimetres or inches, excluding the bezel, and note the aspect ratio. Then match both to the filter, for example 14 inch in 16:10. Filters cut for the wrong ratio may leave gaps or overlap the bezel.
What does blue light reduction on a screen protector do?
It filters out part of the blue light that the display emits, and the product details state how much. In our range the figures go up to 51%. It can make the picture look slightly warmer, but it does not replace regular breaks from the screen.
Can I use a laptop privacy filter on a tablet or monitor?
Only if the filter is made for that device and matches the screen size and ratio. Our range includes a few filters for tablets and one listed for both monitors and laptops. For other devices, check the product details before buying.
