PC connection to monitor

[Nero37]

Now, I know Compaq was discontinued. But I still have a PC. And I would LOVE to get it up and running. Everything seems to function on the PC, but there's one issue I cannot seem to find a way around. Whenever I have the VGA cable plugged in, the monitor says "VGA: No Signal" and then goes to sleep. Yet, when i unplug the VGA cable, it displays "Check Video Cable". I plug the VGA back in and.. It immediately goes to sleep. What is the issue with this? I really can't wrap my head around it..

Thank you for posting on the HP Support Community.

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.

Configure the display with the display driver:

Use the video or graphics card driver to configure touch screen display settings.

1. Look for a graphics card or video card sticker on your computer. Common graphics cards include ATI, AMD, NVIDIA, and Intel.

2. Right-click an empty space on the desktop, and then click the Settings or Control option that matches your graphics card.

   Your graphics card control panel displays.

3. Click the Display, Arrange, or similar option, and then click Multiple Displays, if necessary.

4. Select the display option you want, such as Clone, Duplicate or Extended option.

5. Click Apply or Finish, if necessary.
