For analog VGA/YPbPr and dual-link DVI, a powered active adapter is required for compatibility and does not rely on dual mode. Active VGA adapters are powered by the DisplayPort connector directly, while active dual-link DVI adapters typically rely on an external power source such as USB This converter facilitates the connection between a device with a Mini DisplayPort and a DVI display or monitor. The audio support you need: If you need audio support, make sure to choose a converter that supports audio.

While you can go from a displayport to VGA monitor with a basic adapter(displayport provides power, where VGA doesn't) , I don't believe it's possible (and the your link mentions) that its not possible to go from VGA to DisplayPort, what's powering the conversion of the signal? The system has detected a link failure and cannot set the requested resolution and refresh rate. Your display might not support the requested resolution or there may be an issue with the cable connecting the display to your computer." Read the instructions that come with your converter. This will help you to ensure that you are using the converter correctly. Thankfully, most DisplayPort problems are relatively easy to avoid or fix. Here are four common DisplayPort problems, along with advice for diagnosing and solving them. Display Adapter Link Failure 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. They probably just don't have the A to D hardware in the monitor and really didn't gear the thing for people putting the adapter on the other end.

They just work.

VGA on the other hand is analog and requires extra equipment on the monitor side to convert analog to digital. Convenience: DisplayPort converters are easy to use. Simply connect the converter to your DisplayPort device and then connect the converter to your display. If I remember correctly**, displayport actually can be run from VGA without an active adapter because displayport was based on DVI. Flexibility: DisplayPort converters allow you to connect a DisplayPort-equipped device to a display with a different type of input. This can be useful if you have a new laptop or computer with a DisplayPort output, but you have an older monitor or projector that only has HDMI, DVI, or VGA inputs. This converter is used to connect a device with a Mini DisplayPort to a VGA display or monitor, enabling video output.

DisplayPort to multi-monitor converter: This type of converter allows you to connect multiple displays to a single DisplayPort device. DisplayPort to USB-C converter: This type of converter allows you to connect a DisplayPort-equipped device to a display with a USB-C input.

USB-C

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. On the monitor side however, it sounds like the monitor itself may be pure digital. 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.

Troubleshoot any problems. If you are having problems with your DisplayPort converter, try troubleshooting the problem by following the steps below: The item(s) are returned within 30 days of cancellation. The 30 days start the day after you have notified us of the cancellation

so what I'm trying to find out is if there is another adapter i could use to get the second monitor to connect and work properly.
