Prolonged display (that stays on the screen in a fixed position, remaining static) of HUD elements on certain CRT-based screens may cause permanent damage in the form of burning into the inner coating of the television sets. It is a risk for players who play games with HUD elements for extended periods of time.
In computing, hardware overlay, a type of video overlay, provides a method of rendering an image to a display screen with a dedicated memory buffer inside computer video hardware. The technique aims to improve the display of a fast-moving video image — such as a computer game , a DVD , or the signal from a TV card .
The two images are usually positioned in the compositing phase in close overlay registration (of the main subject), and are then combined using an additive blend mode. Plugins for some of these programs as well as programs dedicated to anaglyph preparation are available which automate the process and require the user to choose only a few basic ...
Video overlay is any technique used to display a video window on a computer display while bypassing the chain of CPU to graphics card to computer monitor. This is done in order to speed up the video display, and it is commonly used, for example, by TV tuner cards and early 3D graphics accelerator cards.
A reticle, or reticule [1] [2] also known as a graticule, is a pattern of fine lines or markings built into the eyepiece of an optical device such as a telescopic sight, spotting scope, theodolite, optical microscope or the screen of an oscilloscope, to provide measurement references during visual inspections.

A major difference between augmented reality and straightforward image recognition is that one can overlay multiple media at the same time in the view screen, such as social media share buttons, the in-page video even audio and 3D objects. Traditional print-only publications are using augmented reality to connect different types of media.
Each overlay inherits its colour from the previous overlay, so only the first of any colour grouped overlays needs to have its colour set. Each overlay is configurably wikilinkable by the template. The overlays can be turned off by setting overlay to 'no', which will result in the only the image and legend being displayed.
