BENFEI Active DVI-D to VGA Adapter, DVI-D 24+1 to VGA Male to Female Adapter

Product Information

High-Definition Multimedia Interface (HDMI), a forward-compatible standard that also includes digital audio transmission So you can use it to connect to a secondary old monitor or TV that only has DVI or VGA inputs. The output resolution will be good enough for documents and watching movies but it won’t be true-HD and I definitely do not recommend it for games. DVI is limited to the RGB color model while HDMI also supports YCbCr 4:4:4 and YCbCr 4:2:2 color spaces, which are generally not used for computer graphics. Digital video pixel data is transported using multiple TMDS twisted pairs. At the electrical level, these pairs are highly resistant to electrical noise and other forms of analog distortion.

The Best DVI Cable for 144hz | The Technology Land". thetechnologyland.com. 2019-08-21 . Retrieved 2022-07-14.An earlier attempt to promulgate an updated standard to the analog VGA connector was made by the Video Electronics Standards Association (VESA) in 1994 and 1995, with the Enhanced Video Connector (EVC), which was intended to consolidate cables between the computer and monitor. [3] [4] EVC used a 35-pin Molex MicroCross connector and carried analog video (input and output), analog stereo audio (input and output), and data (via USB and FireWire). At the same time, with the increasing availability of digital flat-panel displays, the priority shifted to digital video transmission, which would remove the extra analog/digital conversion steps required for VGA and EVC; [5] :5–6 the EVC connector was reused by VESA, [6] which released the P&D standard in 1997. [3] P&D offered single-link TMDS digital video with, as an option, analog video output and data (USB and FireWire), using a 35-pin MicroCross connector similar to EVC; the analog audio and video input lines from EVC were repurposed to carry digital video for P&D.

Like other ways of transmitting video, there are two different regions: the active region, where pixel data is sent, and the control region, where synchronization signals are sent. The active region is encoded using transition-minimized differential signaling, where the control region is encoded with a fixed 8b/10b encoding. As the two schemes yield different 10-bit symbols, a receiver can fully differentiate between active and control regions.

To promote interoperability between DVI-D and HDMI devices, HDMI source components and displays support DVI-D signalling. For example, an HDMI display can be driven by a DVI-D source because HDMI and DVI-D both define an overlapping minimum set of supported resolutions and frame buffer formats. Most modern graphics cards have abandoned VGA ports but they still have one or more DVI ports. It’s rumored these connectors will be abandoned soon too. DVI connectors use digital signals, and the DVI-I version has a couple of pins for analog signals, so you can easily convert to VGA with a simple port converter (more on that later). Intel Newsrom – Leading PC Companies Move to All Digital Display Technology, Phasing out Analog (8. December 2010)DVI's digital video transmission format is based on panelLink, a serial format developed by Silicon Image that utilizes a high-speed serial link called transition minimized differential signaling (TMDS).

However, DVI-I and DVI-D are still found on monitors and computers. I won’t be talking about DVI-A in this article because it’s rarely used today. Because P&D was a physically large, expensive connector, a consortium of companies developed the DFP standard (1999), which was focused solely on digital video transmission using a 20-pin micro ribbon connector and omitted the analog video and data capabilities of P&D. [4] :3 [5] :4 DVI instead chose to strip just the data functions from P&D, using a 29-pin MicroCross connector to carry digital and analog video. [8] Critically, DVI allows dual-link TMDS signals, [9] meaning it supports higher resolutions than the single-link P&D and DFP connectors, which led to its successful adoption as an industry standard. Compatibility of DVI with P&D and DFP is accomplished typically through passive adapters that provide appropriate physical interfaces, as all three standards use the same DDC/EDID handshaking protocols and TMDS digital video signals.

Do remember that only DVI-I supports both analog and digital, DVI-D only works with digital, so you’ll need an active adapter to convert that to another type of connector.

IEEE 1394 was proposed by High-Definition Audio-Video Network Alliance ( HANA Alliance) for all cabling needs, including video, over coax or 1394 cable as a combined data stream. However, this interface does not have enough throughput to handle uncompressed HD video, so it is unsuitable for applications such as video games and interactive program guides.a b "VESA Standards".
