Specifications [ edit ] A passive DVI-to-VGA adapter. This adapter will not work with a DVI-D output. It requires a DVI-I or DVI-A output to get the analog signal to a VGA input (even if the adapter looks like a DVI-D). A more expensive active adapter (or converter) is required to connect DVI-D to VGA. Digital [ edit ] DisplayPort is common on new graphics cards and monitors, but this can lead to problems when you have older hardware without a DP interface. To ensure a basic level of interoperability, DVI compliant devices are required to support one baseline display mode, "low pixel format" (640×480 at 60Hz).

One of the purposes of DVI stream encoding is to provide a DC-balanced output that reduces decoding errors. This goal is achieved by using 10-bit symbols for 8-bit or less characters and using the extra bits for the DC balancing. Dual-link DVI connections aren’t widely used, but you would need a special dual-link cable if your device does have this interface. Can You Convert DVI to HDMI? DVI-A connectors have 17 (12+5) pins, do not have a dual-link option, and only carry analog signals. These signals are identical to VGA signals but are presented as an altered configuration. A VGA to DVI adapter is necessary to connect a VGA video card to a DVI-A monitor or a DVI-A video card to a VGA monitor. Due to VGA being the dominant connector for analog monitors and DVI as a standard for digital signals, DVI-A connectors are quite rare; instead, DVI-I and DVI-D connectors are more common. DVI-A cables will work with both DVI-A and DVI-I connectors. Male DVI-D cables may fit in a female DVI-A connector, but will not work as they do not carry any analog signals.

Single Link and Dual Link

Therefore if your display device only accepts DVI-D (digital), this won’t work. Can You Connect DisplayPort to DVI?

Female M1-DA connector pins (view of plug) DVI port on a Sony HD CRT TV that complies with EIA-861 DVI output connector on a computer 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. VESA Plug and Display (P&D) Standard, Version 1" (PDF). Video Electronics Standards Association. June 11, 1997. Archived from the original (PDF) on July 4, 2003. It doesn’t send audio, so you must make a separate sound connection between the source device and the speaker system.

Signal quality considerations

Generalized Timing Formula (GTF) is a VESA standard which can easily be calculated with the Linux gtf utility. Coordinated Video Timings-Reduced Blanking (CVT-RB) is a VESA standard which offers reduced horizontal and vertical blanking for non-CRT based displays. [15] Digital data encoding [ edit ] This VGA to DVI-A adapter lets you connect an older device with a VGA output – like a graphics card – to a DVI-A input on your display device, like a monitor or projector. The DVI specification includes signaling for reducing power consumption. Similar to the analog VESA display power management signaling (DPMS) standard, a connected device can turn a monitor off when the connected device is powered down, or programmatically if the display controller of the device supports it. Devices with this capability can also attain Energy Star certification. DisplayPort only natively supports single-link DVI, not dual-link. However, active dual-link adapters are available, which are more expensive. DVI-D single link has the same bandwidth as DVI-I single link, so the maximum resolution is the same at 1920×1200 at 60 Hz.

DVI-I (Digital Video Interface - Integrated): As the name suggests DVI-I supports both analog and digital signals but not both at the same time. The user has to choose the type when both are supported at the other end. DVI-I port can be connected to both VGA monitors and HD monitors. There are two types in DVI-I. They are Single Link DVI-I and Dual Link DVI-I. The pin configuration for both is given below. You can see in pin diagram the DVI-I pins are a combination of both DVI-A and DVI-D. DVI-I (Single Link) supports a video stream at 1920X1200 @ 60 Hz. DVI-I (Dual Link) support a video stream at 2560X1600 @ 60 Hz. Fortunately, DisplayPort is compatible with DVI; you just need to buy the correct cable or adapter.To convert DVI to HDMI you’ll need a passive physical adapter. The good news is both DVI-I and DVI-D can be converted to HDMI because they both use digital signals.
