Targus 4Vu Privacy Screen for 20.1-Inch Monitors (4:3, ASF201USZ)

The screen works well – when you're off-angle, it's dark. It's exactly what I need in a open office. The only issue is it slightly reduces brightness at direct view.

I work with confidential data and this screen is a lifesaver. The anti-glare is also a bonus. Easy to attach and remove. Highly recommend.

The privacy function works, but the screen is a bit too big for my 20.1" monitor – it hangs over a little. It's still usable and keeps prying eyes out.

This is a sturdy privacy screen. It snaps on securely and the viewing angle is perfect. It has saved me from many awkward moments in the office.

It takes a few tries to get the angle right so you see clearly and others see dark. Once set, it's great. It also doesn't interfere with touch screen (if you have one).

I've used privacy screens before and this one is top-notch. The adhesive strips are good and it doesn't leave residue. Worth the money.

It didn't stick well to my monitor and the screen wasn't large enough to cover the entire display. The visual effect is okay, but it's a hassle.

I feel much more secure with this privacy screen. My desk faces a window and the reflection is also reduced. Great product.

It does the job of blocking side views. The installation was straightforward. The only downside is that it makes the screen a bit darker, so I turn up the brightness.
