WiDi
Wireless Display (WiDi) is discontinued technology developed by Intel that enables users to stream music, movies, photos, videos and apps without cables from a compatible computer to a compatible HDTV or through the use of an adapter with other HDTVs or computer monitors. Intel WiDi supports HD 1080p video quality, 5.1 surround sound, and low latency for interacting with applications sent to the TV from a PC running Windows 7 or later. Using the Intel WiDi Widget, users can perform different functions simultaneously on their PC and TV such as checking email on the PC while streaming a movie to the TV from the same device. WiDi development was discontinued in 2016 in favor of Miracast, a standard developed by the Wi-Fi Alliance and natively supported by Windows 8.1 and later. Intel's Wireless Display should not be confused with Microsoft's Windows 11 operating system's built-in ''Wireless Display'' app (formerly ''Connect'') which works with Miracast.

Wireless HDMI
Wireless HDMI is the wireless transmission of high-definition audio and video signals between devices, using unlicensed radio frequencies like 5 GHz, 60 GHz, or 190 GHz. This technology eliminates the need for an HDMI cable, allowing users to transmit signals wirelessly between the component device and the display device. Wireless HDMI converts the HDMI cable signal into a radio frequency which is broadcast across the wireless spectrum. This allows for video source and display device to be in different rooms, without the need for cables. The technology emerged in the early 2000s. Examples * Proprietary protocols for wireless transmission, e.g., LG "Wireless 1080p", Philips "Wireless HDTV Link", Sony "Bravia Wireless Link", Asus "Wireless Display Connectivity", etc. * Proprietary video compression schemes that work over 802.11n and similar wireless interfaces * WirelessHD * Wireless Home Digital Interface * WiGig * Asus WAVI (Wireless Audio Video Interaction) wireless HDMI us ...

WiGig
WiGig, alternatively known as 60 GHz Wi-Fi, refers to a set of V band, 60 GHz wireless network protocols. It includes the current IEEE 802.11ad standard and also the IEEE 802.11ay standard. The WiGig specification allows devices to communicate without wires at multi-gigabit speeds. It enables high-performance wireless data, display and audio applications that supplement the capabilities of previous wireless LAN devices. WiGig tri-band-enabled devices, which operate in the 2.4, 5 and 60 GHz bands, deliver data transfer rates up to 7 gigabit, Gbit/s (for 11ad), about as fast as an 8-band IEEE 802.11ac, 802.11ac transmission, and more than eleven times faster than the highest IEEE 802.11n-2009, 802.11n rate, while maintaining compatibility with existing Wi-Fi devices. The 60 GHz millimeter wave signal cannot typically penetrate walls but can propagate by reflection from walls, ceilings, floors and objects using beamforming built into the WiGig system. When r ...

Mobile High-Definition Link
Mobile High-Definition Link (MHL) is an industry standard for a mobile audio/video interface that allows the connection of smartphones, tablets, and other portable consumer electronics devices to high-definition televisions (HDTVs), audio receivers, and projectors. The standard was designed to share existing mobile device connectors, such as Micro-USB, and avoid the need to add video connectors on devices with limited space for them. MHL connects to display devices either directly through special HDMI inputs that are MHL-enabled, or indirectly through standard HDMI inputs using MHL-to-HDMI adapters. MHL was developed by a consortium of five companies: Nokia, Samsung, Silicon Image, Sony and Toshiba. History Silicon Image, one of the founding companies of the HDMI standard, originally demonstrated a mobile interconnect at the January 2008 Consumer Electronics Show (CES), based on its transition-minimized differential signaling (TMDS) technology. This interface was termed "Mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Computer Display Standards
Computer display standards are a combination of aspect ratio, display size, display resolution, color depth, and refresh rate. They are associated with specific expansion cards, video connectors, and monitors. History Various computer display standards or display modes have been used in the history of the personal computer. They are often a combination of aspect ratio (specified as width-to-height ratio), display resolution (specified as the width and height in pixels), color depth (measured in bits per pixel), and refresh rate (expressed in hertz). Associated with the screen resolution and refresh rate is a display adapter. Earlier display adapters were simple frame-buffers, but later display standards also specified a more extensive set of display functions and software controlled interface. Beyond display modes, the VESA industry organization has defined several standards related to power management and device identification, while ergonomics standards are set by the TCO. ...
