Best Computer Screen Protector of 2019

A lot of individuals think that having a strong password or solid encryptions is the solution to keeping their private work in their computers protected. To some extent, this might be true, but one thing you need to know is that, even with these passwords, private information can still leak through visual hacking.

To ensure that your work is 100% safe, you need to get a privacy computer screen protector. Such a screen will prevent curious onlookers from gaining access to your data by just peering over your shoulders or taking snapshots on your display as the filter makes everything appear dark if one is viewing from the sides.

There are a lot of computer screen protectors in the market today making it a little challenging to get the right one for your monitor. Even if you have an idea of the brand you want to purchase from, there are still some important aspects you have to consider first before paying for the filter.


The following are some of the things you need to consider before purchasing a computer screen protector.

Determine Your Screen Type

Different computers have different types of screens. You, therefore, have to ascertain the type of your screen before going for one. Confirming the screen type will help you to get the right measurements which will in return help you to get the right filter for your monitor with ease.

There are two types of screens;

  1. The raised bezel – The screen has a raised frame around the edges
  2. The flat bezel – The screen has an edge to edge glass and lacks a raised frame


Measure Your Screen

After determining the type of your screen, you need to get its measurements to get a filter that fits well. When measuring, you need to do it according to the type of your screen.

For the raised bezel screen, ensure that you measure the length and width of the viewing area. For a flat bezel, you need to measure the full length and width from edge to edge. Getting the correct measurements is very crucial since it’s the only way to getting the right filter for your computer.

Should you find that the selected filter fails to match with your measurements, go for a smaller screen but ensure that it’s close to your values.


Image Clarity

A good filter should not obstruct you from reading the contents on your computer. A filter that blocks you from getting access to your work is useless, and you thus have to get a protector that enables you to see everything with ease.

Privacy filters block some light from computer screens making them dimmer. Go for a protector that even after blocking the light enables you to read from your display with ease.


Reversible Filter

A reversible screen protector enables you to choose a matte or gloss side before installing it.

Going for such a screen is advantageous because, with it, you can select the finish you prefer. The matte one blocks distraction reflections but can also make colors to appear dull.



The way to install a filter screen varies from model to model. You, therefore, need to go for a protector that you can install and remove with ease.

Ask for installation instructions when purchasing as the guidelines make the process less tiresome and fast. If you can get a screen with multiple attachment options, the better.



Screen filters come in different colors, the dominant being black. You can use the black filter both outdoors and indoors without suffering from eye strain.

Filters that give off a gold sheen tend to be more reflective than the black ones and thus not advisable to use outdoors. Whichever color you choose to go for, ensure that it blocks viewers from seeing whatever is on your display from the sides.



Before you go for a screen protector, you have to decide on the amount you are willing to spend on it. Even though you can get privacy filters at as low as $20, always consider the functionality of the screen in question first.

Do not just purchase one because it comes at a low price. Always remember that cheap can sometimes become expensive.

However, if on a tight budget you can consider going for one that comes at a price favorable to you. You should also consider going for screens that come with a warranty so that if you get dissatisfied with the functionality, all you’ll have to is return it and get a full refund.



Always go for screens that have an anti-scratch coating. The coating helps in keeping scratches from your screen enabling you to read with ease. Ensure that you get a micro-fiber cleaning cloth to clean the screen as well.


Micro-Louvre Technology

Micro-louvre technology helps in making everything on your screen only accessible to you when sitting directly in front of your computer.

Anybody else sitting from the sides gets blocked away and no matter how hard they try to crane their necks; they can’t see anything. Always get a screen that uses this technology if you want to use your computer without fear even in crowded areas.
