This article covers LG 27GP850-B.

Overview

The ATEN 2L-7D02D is a 2-meter dual-link DVI-D cable designed for professional environments where high-resolution digital video transmission over DVI is still required. With support for resolutions up to 2560×1600 (WQXGA) and refresh rates beyond 120Hz at lower resolutions, this cable is a reliable choice for digital signage, medical displays, and industrial workstations that rely on legacy DVI interfaces. Dual-link DVI-D doubles the bandwidth of a single-link connection, making it possible to drive high-resolution monitors with a single cable. Although HDMI and DisplayPort have largely replaced DVI in consumer settings, many business-grade monitors, projectors, and KVM extenders still use DVI-D as their primary input, keeping the demand for quality DVI cables steady.

Connectivity & Compatibility

Connector type: DVI-D dual-link male to male (24-pin configuration). Physically incompatible with single-link (18-pin) or DVI-I (analog+digital) ports Maximum supported resolution: 2560×1600 at 60Hz, or 1920×1200 at higher refresh rates (up to 144Hz depending on GPU and monitor) Digital-only signal; no analog (DVI-A) compatibility. Use a DVI-I or analog adapter if you need legacy VGA output Cable length of 2 meters suits most desk setups, but for longer runs (e.g., rack-to-desk) consider signal degradation beyond 5 meters without active repeaters

Product Info

ATEN is a well-known Taiwanese manufacturer of KVM switches and video extension gear, and the 2L-7D02D is part of their 2L-7 series of premium DVI cables. Market positioning is entry-to-mid range, with a retail price around $8-10 USD (approximately 1,000 JPY). The cable comes with a standard 2-year warranty from ATEN and is widely available through online retailers like and electronics stores. In the box you get just the cable itself—no additional adapters or accessories. It ships in simple polybag packaging, keeping costs low. Availability is generally good, with frequent restocks.

Best Use Cases

Users with older dual-link DVI monitors that require 2560×1600 resolution for CAD, medical imaging, or financial trading screens System administrators or event technicians maintaining DVI-based video infrastructure in conference rooms, control rooms, or digital signage setups * Budget-conscious builders who need a reliable DVI-D cable from a reputable brand without spending on overbuilt audiophile cabling

Things to Consider

Always verify that both the monitor and the graphics card support dual-link DVI-D before purchase. Single-link ports will not physically accept a 24-pin plug. Modern GPUs increasingly omit DVI ports entirely; if you are using a DisplayPort-to-DVI adapter, ensure it supports dual-link bandwidth—many cheap adapters only pass single-link signals. The 2-meter length is practical for desktop use, but for longer runs (e.g., ceiling-mounted projectors) you may need a 3-meter or 5-meter variant—ATEN offers the same cable in various lengths within the 2L-7 series.
