The P134-000-50BK is a bulk pack of fifty (50) P134-000 DisplayPort to DVI Cable Adapters (M/F). Each adapter connects a DisplayPort computer or tablet to the DVI input port on a monitor, projector or television. With a male DisplayPort connector and a female DVI-I dual-link connector, each adapter lets you use your existing DVI display instead of buying a new DisplayPort monitor.Ideal for displaying video on a large monitor or digital sign, these six-inch adapters support DVI-D single-link computer video resolutions up to 1920 x 1200 and HD video resolutions up to 1920 x 1080 (1080p). Because they are passive adapters, these units require that the connected source device have a DP++ port, which allows HDMI and DVI signals to pass through (check your DisplayPort source's documentation for compatibility). Foil and braid shielding delivers reliable, error-free signal quality and protection from EMI/RFI line noise that can distort or destroy data. Fully molded ends with corrosion-resistant gold-plated contacts provide maximum conductivity and minimize data loss. Integral strain relief gives the cable extra flexibility, reduces stress, and helps the cable and connectors move freely without cracking. These P134-000 adapters are plug-and-play units with no software, drivers or power supply needed. They fit easily in a briefcase, backpack or laptop bag for connecting on the go.
