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.

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 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.

Displayport To Vga Adaptors

If I remember correctly**, displayport actually can be run from VGA without an active adapter because displayport was based on DVI. Mini - commonly used for the DisplayPort output on notebook PCs including Apple products which includes Thunderbolt. Benefits of DisplayPort

VGA on the other hand is analog and requires extra equipment on the monitor side to convert analog to digital. 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. Displayport cables are high performance digital cables used to connect computer monitors, laptops, and other devices to display screens. It supports the transmission of high-resolution video and audio signals, making it a popular choice for connecting devices that require high-quality display output. A display port is always male on the cable and female on the device. All DP cables have the same basic layout and wiring and will support any feature including audio, daisy-chaining, HDR and DSC. You can learn more in our guide to DisplayPort cables. How are DisplayPort Cables Classified? So, I setup a new tunnel today with one of other buildings, and the tunnel will not connect. I get an IP spoof in the SonicWALL logs, and the link never establishes. I am assuming because both of the public IPs are in the same subnet and sonicwall doesn't...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. essjae That's not entirely true. VGA is an analog signal, but the DVI interface is a digital interface which was engineered in a way to be electrically identical to a properly functioning VGA signal, so only a pinout change is needed. (Isn't a true digital signal really just a square waveform?) Before choosing the cable, you will need to consider the connector type on each end of the cable and also the cable length. Types of DisplayPort DisplayPort cables are used with a range of devices including tablets, notebooks, desktop computers, monitors and televisions and include benefits such as: https://en.wikipedia.org/wiki/DisplayPort Opens a new window (Article indicates passive DP/HDMI adapters are possible, so I don 't know why a passive VGA>HDMI wouldn't be possible but I've never seen one)
