Answer: Digital Projectors
If you’ve ever sat very close to a projection screen during a digital slideshow at work or school, there is a good chance you’ve seen the “screen-door effect” up close and personal. In digital projection, the effect is a visual artifact created by the fine lines between the individual pixels in the panel inside the projector.
The reason we can see the little lines is because the optical components of the projector (the lens system) can project the display with a greater degree of image resolution than the actual digital panel inside can create. As such, it’s like holding a powerful magnifying glass up to a printed page and seeing imperfections in the offset printing process.
Some of the tricks engineers have employed to deal with this visual artifact include depixelization, which uses various optical methods (a microlens array, for example) to eliminate the visibility of the spaces between the pixels, and setting the lens very slightly out of focus so that the individual pixels bleed into each other just enough to erase the black lines in the process.

Windows software downloads are a mess. Many programs try to drag adware and other malicious junk onto your computer. Even safe programs we test sometimes turn to the dark side and start bundling junk later.

MAC address filtering allows you to define a list of devices and only allow those devices on your Wi-Fi network. That’s the theory, anyway. In practice, this protection is tedious to set up and easy to breach.
