Dual Monitors for Extended use using my HP Pavilion Desktop - 550-153w

[phillyoe]

Hello, 

I am trying to set up my computer for dual-screen extended monitor use and I am struggling! My HP Pavilion Desktop - 550-153w has one HDMI output and 1 Dsub output. I went to best buy and bought an HDMI splitter thinking that would be the easy fix but learned that would only duplicate my monitors, not extend them. I have a Dsub to HDMI cord but it will not detect in the display settings. How can I accomplish my goal? WIll I have to add a second HDMI output to my computer? The sticker on the side of the tower says it can handle dual displays, but I never thought it would be this complicated. Thanks to anyone who can help!

@phillyoe Here's all you need to know about resolving your concern:

Step 1: Connect the second display

Computers and TVs have a wide variety of video connection types. The video connection on your computer must match the connection on your TV or monitor.

NOTE: 

If your PC only has DVI and your TV does not have a DVI port, you can use a special adapter or converter cable.

1. Select a connection type based on your second monitor.

   • Monitor: VGA  or DVI  cable

   • TV: Video (composite)  or S-video  cable

   • High Definition TV: DVI  or HDMI  cable

2. Connect the TV or monitor to the computer using the cable you chose.

3. Connect a power cable to the TV or monitor, and then turn it on.

4. TV connections only: Change the TV video input source to match the video source connection from the computer (Line-1, Video-1, HDMI, etc.). Refer to documents that came with the TV for instructions.

   Depending on the TV, the image quality might not be as good as that of a monitor.

5. Turn on the computer.

So I was able to get it to work after purchasing a new adapter. My D-sub to HDMI cable (all in one cord) would simply not work. I had to buy a D-sub to HDMI Adapter to get it to work. The adapter attaches to my tower D-sub output and has to plug in a USB into the tower as well. A normal HDMI cord then goes into the adapter and into the monitor, making the second screen detectable. I bought the adapter at Walmart for about $30. I hope this helps others that find themselves struggling when there is only one HDMI output in your tower but you want split screens!
