I have 9 point connection on my computer and am trying to do a double monitor. The 9 point says 10101 A. Is there a connector for this to an HP2009m Monitor?

I think that the port you're referring to is a RS-323 port (Serial Port). This port was used for serial communication back before USB existed (For connecting a mouse and that sort of things). The 10101 label on the port is just a string of ones and zeros (Serial communication).
This port doesn't output a video signal, so you can't hook up a monitor to it.If you want to connect a monitor to your computer, you should look for a VGA, DVI, HDMI or DisplayPort port on your computer. If there aren't any or they are all occupied, you can buy a video card and install it on one of your PCIe slots.

I'm an expert in computer hardware and connectivity, and I can confidently provide information on the concepts discussed in the provided article.

The user, Dana Miller, is facing a challenge with a 9-point connection on their computer and is attempting to set up a dual monitor configuration with an HP2009m monitor. The 9-point connection is labeled as 10101 A. A response from Ahmed Ashour suggests that this port is likely an RS-323 port, also known as a Serial Port. This port was historically used for serial communication, such as connecting a mouse.

However, Ahmed Ashour clarifies that the 10101 label on the port is merely a string of ones and zeros representing serial communication and that this port doesn't output a video signal. Consequently, connecting a monitor directly to this port is not possible. The user is advised to look for VGA, DVI, HDMI, or DisplayPort ports on their computer for monitor connectivity. In case these are unavailable or occupied, the suggestion is to purchase a video card and install it in one of the PCIe slots.

The article also mentions relevant tags such as "windows-10" and provides links to related questions, including one about connecting a VGA monitor to a 9-pin serial port.
