BENFEI DisplayPort to VGA Cable, 1.8M Display Port of Computer/Laptop to VGA of Monitor/Projector Gold-Plated Adapter (Not Bidirectional,Not Compatible with HDMI or USB)

Product Information

standard and fully backwards compatible • Supports resolutions up to 1920x1200 (60Hz) • DDC Speed control for use with long VGA cables • ED. For analog VGA/YPbPr and dual-link DVI, a powered active adapter is required for compatibility and does not rely on dual mode. i was able to get one of them working on the HDMI port, but am having trouble with the second monitor on the vga port. Display port to just about anything else on the computer side works because the computer is built to handle both the analog and digital output needed to make it happen, it's part of the standard.

I've used active HDMI to VGA since HDMI has the opposite issue, and it worked surprisingly well, but I wouldn't want to use it permanently, I don't trust stuff like that not to burn out. Connect a VGA monitor to a mini DisplayPort source; ideal for connecting a secondary display • Compliant with DisplayPort version 1. Today in History: 1814 Congress of Vienna opens to re-draw the European political map after the defeat of France in the Napoleonic WarsThe ‘long 19th century’ was a period of relative peace that began arguably with the Congress of Vienna in September 1814. The active adapter externalizes the analog to digital conversion, and it will probably need a power source - probably a USB port, to power it. You're both right, in my experience a digital to analog usually works without the extra power because it uses the power from the digital signal, while an analog signal cannot provide enough power hence the need for external power on the active adapter.However, for really high resolutions and frame rates, other options like a DisplayPort might be better.

There needs to be a conversion of the signal, and that requires external power, usually there's a USB connection on an active adapter. If I remember correctly**, displayport actually can be run from VGA without an active adapter because displayport was based on DVI. Displayport cables are high performance digital cables used to connect computer monitors, laptops, and other devices to display screens. Connect a VGA monitor to a DisplayPort source • Integrated chip provides active conversion • Supports PC resolutions up to 1920x1200 and HDTV resolutions up to 1080p • Easy installation, no software required • DisplayPort male to VGA female connections .

Portable adaptor that lets you connect a legacy VGA display to a DisplayPort source, ideal for adding a secondary display to your laptop or PC. DisplayPort is a newer standard originally developed to support the higher performance requirements of personal computers, enabling an increase in performance and integration. My guess is that DVI-D to Display port with work, HDMI to Display Port, and obviously Display port to Display port because they're all digital. Long story short, it's cheaper to go all digital from a manufacturing perspective, no more A to D conversion, and the picture looks better anyways.
