DICOTA Privacy Filter 2-Way Adhesive for 17.3" 16:9 laptops
2-way privacy ±30°Adhesive, stays on screenBlue light up to −42%17.3" 16:9
The DICOTA D50030-2AD is a 2-way privacy filter for 17.3-inch laptop screens with a 16:9 aspect ratio: anyone looking from the left or right beyond roughly 30 degrees sees a darkened screen, while you see the image normally from the front. It suits people who work on trains, in airports, in open-plan offices or at reception desks where customer data, emails or financial figures are on screen.
This is the adhesive version. A self-adhesive silicone layer holds the filter flat on the display without bubbles, and DICOTA states that it can be removed without leaving residue. It is designed to stay on the screen, which makes it the tidier choice when privacy is needed every working day.
Besides privacy, the surface is anti-glare and DICOTA states up to 42% blue-light reduction, so the filter also cuts reflections from windows and overhead lighting during long sessions.
Before you order: DICOTA universal filters are sized by visible screen diagonal and aspect ratio. This filter measures 383.0 × 215.0 mm for 17.3" 16:9 screens. Measure the visible display area (not the outer lid) and check the aspect ratio of your laptop: a 17.3" screen with 16:10 proportions will not be covered correctly.
What's in the Box
- 1 × DICOTA 2-way privacy filter 17.3" 16:9 (383.0 × 215.0 mm)
- Mounting material for the adhesive installation
What It Means in Practice
- From the front the image stays clear, but it looks somewhat darker because the filter transmits up to 75% of the light; most users raise screen brightness one or two steps.
- A colleague next to you or a passenger in the next seat sees a dark screen; someone standing directly behind you can still read it, because a 2-way filter only narrows the left and right viewing angles.
- Touchscreen laptops keep working through the filter, according to DICOTA.
- Once applied, the filter lies flat and stays put; there are no holders on the bezel and nothing to lose in a laptop bag.
What Will Not Work
- Privacy from above or below: this is a 2-way filter. For vertical privacy as well, a 4-way filter is needed.
- Screens with a size or aspect ratio other than 17.3" 16:9: the filter will either leave a strip uncovered or overlap the bezel.
- Frequent on/off use: the adhesive version is meant to stay on the screen. If you want to remove it several times a day, a side-mounted version is the better fit.
- Protection from someone standing directly behind you.

Frequently Asked Questions
How do I know which size to order?
Measure the visible screen diagonal and check the aspect ratio in your laptop specifications. This filter is 383.0 × 215.0 mm and matches 17.3" 16:9 panels.
Does it block someone looking from above?
No. A 2-way filter narrows the left and right viewing angles only.
Can I remove it later?
Yes. DICOTA states the silicone layer comes off without residue, but the filter is designed to stay on the screen rather than come on and off daily.
Singular Expert Insight · Buyer's Guide
Privacy filters fail on fit far more often than on optics: a 17.3" 16:9 filter on a 17.3" 16:10 screen leaves a strip uncovered. Confirm the aspect ratio first, then choose the mounting style that matches how you work — adhesive if it will stay on permanently. For other sizes and mounting types, see our
privacy filters and screen filters.
✓ Buy it if you work in public or shared spaces on a 17.3" 16:9 laptop and want to keep side viewers out with a filter that stays permanently on the screen.
✕ Skip it if your laptop is not 17.3" 16:9, or you also need privacy from above (choose a 4-way filter).
→ Also consider a DICOTA 4-way privacy filter if you work in standing environments where people view your screen from above.
