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 .
A video overlay device can be connected between the graphics card analog VGA output and the monitor's input, forming a "VGA passthrough". The device modifies the VGA signal and inserts the analog video signal overlay into the picture; the rest of the screen is filled by the signal coming from the graphics card. The driver software informs the ...
Players can add non-Steam games to their libraries, allowing the game to be easily accessed from the Steam client and providing support where possible for Steam Overlay features. The Steam interface allows for user-defined shortcuts to be added. In this way, third-party modifications and games not purchased through the Steam Store can use Steam ...
Some games, in an attempt to increase player immersion and reduce potential screen clutter, have most or all elements disappear when not needed (usually when the status they display is static), a method commonly referred to as a "dynamic HUD". In most cases, the player can display them all by pausing the game or pressing a button.
The Akai VS-2 was the first VCR with an on-screen display, originally named the Interactive Monitor System. By displaying the information directly on the television screen, this innovation eliminated the need for the user to be physically near the VCR to program recording, read the tape counter, or perform other common features.
In Blue Only mode only the blue pixels of a display render the picture on the screen - or, for CRT displays, the blue cathode ray tube. Thus we see only the blue channel of the image, but rather blue tinted than black and white. Areas with blue color in it appear bright and those without blue color appear dark or black.
One of the limitations of WDDM driver model version 1.0 is that it does not support multiple drivers in a multi-adapter, multi-monitor setup. If a multi-monitor system has more than one graphics adapter powering the monitors, both the adaptors must use the same WDDM driver. If more than one driver is used, Windows will disable one of them.

The Vectrex, in contrast to other video game systems at the time, did not need to be hooked up to a television set; it had an integrated (vertically oriented) monochrome CRT monitor. A detachable wired control pad could be folded into the lower base of the console. Games came with translucent color overlays to place over the screen.
