Overview

The StarTech.com DVIDDUAL6 is a 1.8m DVI-D dual link monitor cable designed for pure digital video transmission. It uses a DVI-D dual link connector (29 pins) to deliver resolutions up to 2560×1600 (WQXGA) without analog conversion, ensuring crisp image quality. This cable is a solid choice for connecting a PC or laptop to a DVI-D monitor or projector, especially when you need the extra bandwidth of dual link for higher resolutions or refresh rates. With a length of 1.8 meters, it fits neatly on a desk without excessive cable clutter. The cable is built with gold-plated contacts and foil shielding to minimize interference, making it suitable for both office and home setups.

Connectivity & Compatibility

Connector type: DVI-D dual link (29-pin) male to male Compatible devices: PCs, laptops, graphics cards with DVI-D output; monitors and projectors with DVI-D input Note: Not compatible with DVI-I (analog+digital) or DVI-A (analog) ports. Only works with DVI-D ports. Can physically connect to single-link DVI-D ports, but dual link mode will not be activated unless both source and display support dual link.

Product Info

Best Use Cases

Office workers with dual monitors: If you need to drive two 2560×1440 displays, this dual link cable ensures stable bandwidth. Make sure your monitor has a DVI-D input. Gamers using high-refresh-rate DVI monitors: For 144Hz at 1080p or 120Hz at 1440p, dual link provides the necessary bandwidth (up to 9.9 Gbps). Check that your GPU’s DVI port supports dual link (most do). * Users repurposing an older DVI-D monitor: If you have a quality DVI monitor and want to keep using it, this cable pairs well with a DisplayPort-to-DVI-D adapter. Lossless conversion is possible with active adapters. Not ideal for users who already have HDMI/DisplayPort-only setups or those using analog VGA equipment.
