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 .
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.
Sometimes a shadow can be used to create a visual effect. Areas of the blue screen or green screen with a shadow on them can be replaced with a darker version of the desired background video image, making it look like the person is casting a shadow on them. Any spill of the chroma key colour will make the result look unnatural.
The remaining icon overlay handlers are not used. [2] Many applications such as versioning software like TortoiseSVN and cloud storage synchronization software like Nextcloud, Dropbox, and OneDrive add their own icon overlay handlers to the Registry upon installation. Below is a table of shell icon overlay identifiers by software.

Greenshot is a free and open-source screenshot program for Microsoft Windows. It is developed by Thomas Braun, Jens Klingen and Robin Krom [1] and is published under GNU General Public License, hosted by GitHub. Greenshot is also available for macOS, but as proprietary software [2] through the App Store.
Most importantly, the architect can focus on the problem being solved without the added design difficulty of forcing the processing into steps constrained by the overlay size. Thus, the designer can use higher-level programming languages that do not allow the programmer much control over size (e.g. Java , C++ , Smalltalk ).
From 2005 to 2008, 16:10 overtook 4:3 as the highest-selling aspect ratio for LCD monitors. At the time, 16:10 made up 90% of the notebook market, and was the most commonly used aspect ratio for laptops. [2] However, 16:10 had a short reign as the most common aspect ratio.
