DVI and VGA cables connect computers, laptops and graphics cards to monitors, projectors and displays that still use these video inputs. Our range has over 400 models, mostly VGA (D-Sub) and DVI-D cables, plus dual link DVI and a few serial DB-9 and BNC leads. Brands include Delock, InLine, Lindy, Micro Connect and Equip.
How to choose a DVI or VGA cable
Match the connectors on both ends. Check the sockets on your graphics card and your display before anything else. In our range, the most listed connectors are VGA (D-Sub) and DVI-D, available as VGA to VGA, DVI-D to DVI-D and some mixed combinations. Some cables have DB-9 or BNC ends, which are used for serial and professional video equipment rather than ordinary monitors.
Single link or dual link DVI. Single link DVI-D handles Full HD (1920 x 1080) without trouble. Dual link DVI-D (listed as DVI-D (DL)) is the one to choose for higher resolutions such as 2560 x 1600, and it is also fine for lower ones. Make sure the monitor and the graphics output both support dual link as well.
Analogue or digital signal. VGA carries an analogue signal, while DVI-D is purely digital. A plain DVI-D cable cannot be converted to VGA with a simple adapter, because it carries no analogue signal. If you need to go from DVI to VGA, look for DVI-I or DVI-A connectors, or use an active converter.
Length and shielding. VGA is an analogue signal, so long or poorly shielded cables can cause ghosting, soft text and colour fringing. Buy the shortest length that reaches comfortably, and look for double shielding and ferrite cores if the cable runs past power cables or over several metres. Some VGA cables in our range also carry a 3.5 mm audio lead for speakers.

DVI and VGA cables: frequently asked questions
Is DVI better than VGA?
DVI-D is better for most modern displays, because it carries a digital signal straight to the monitor. VGA converts the image to analogue and back, which can soften text at high resolutions. VGA is still useful for older monitors, projectors and many office machines.
Can I connect a DVI port to a VGA monitor with a cable?
Yes, but only if the DVI port carries an analogue signal, as on DVI-I and DVI-A connectors. A DVI-D port is digital only, so a passive cable or adapter will not work. In that case you need an active converter that changes the digital signal to analogue.
What is the difference between single link and dual link DVI?
Dual link DVI uses twice as many data channels as single link, which allows higher resolutions and refresh rates. Single link covers up to 1920 x 1200 at 60 Hz. Dual link is needed for screens such as 2560 x 1440 or 2560 x 1600.
Does a VGA cable carry sound?
No, a standard VGA cable carries video only. If the computer and the display or speakers need to be connected for audio, you need a separate 3.5 mm audio cable. Some VGA cables in our range include a 3.5 mm lead in the same cable to keep things tidy.
