Older computers or monitors may have a d-sub port. D-sub (VGA) only sends analog video. You will not get digital quality or 4k resolution. D-sub does not send audio. You need another cable for sound. For new displays, you can use a USB-C to VGA adapter. These adapters work for basic video up to 1080p.

LimitationDescription
Analog SignalLower image quality, more interference
No AudioNeeds a separate audio connection
Resolution LimitsNot good for 4K or high refresh rates

Tip: Always check compatibility when using adapters. Some monitors need special drivers or settings for the right resolution.

For Multi-Monitor Setups

Displayport is best if you want more than one monitor. Displayport lets you connect many monitors with one cable using MST. This keeps your setup neat and easy. HDMI can work for two monitors. Displayport is better for three or more screens. D-sub does not work well for multi-monitor setups.

  • Displayport supports daisy-chaining to link monitors.

  • You get high refresh rates and 4k on each monitor.

  • This is good for work, gaming, or streaming.

Always check your device ports and cable length before buying. A good digital cable gives better video and fewer problems.

Tips and Mistakes

Check Ports

Always look at your device ports before buying a cable. Not all monitors have the same ports. New monitors often use hdmi, displayport, or USB-C. Old monitors might only have D-Sub. Here’s how you can check:

  1. Look at the back of your monitor and computer.

  2. Find which video ports are there. You might see hdmi, displayport, or D-Sub.

  3. If you use a desktop, check if the ports are on the graphics card or motherboard.

  4. Choose the port that matches both your monitor and computer.

  5. Make sure both devices are turned on before you connect the cable.

  6. After plugging in the cable, set up your monitor in your computer’s settings.

Tip: If you use more than one monitor, try to use the same port type for each. This helps keep the picture and brightness the same.

Most monitors made after 2020 have displayport, hdmi, or Thunderbolt ports. Always check your ports before buying a new cable.

Avoid Adapters

Adapters may seem useful, but they can cause problems. Cheap adapters can show errors like “No Signal” or “Invalid Format.” Sometimes, adapters lower your monitor’s resolution or refresh rate. Here’s a table with common problems:

IssueDetailsImplications
Compatibility or performanceSome adapters don’t work with all displayport or hdmi featuresLower resolution, refresh rate, or no signal
Extra failure pointsAdapters can break or stop workingErrors like “No Signal” or “Invalid Format”

Try to use a direct video cable between your computer and monitor. This gives you the best picture and sound.

Upgrade When Possible

If you still use D-Sub, think about upgrading. New hdmi and displayport cables give much better image quality. You will see sharper pictures and smoother motion, especially with high refresh rate monitors. Here’s why upgrading helps:

  • hdmi and displayport support higher resolutions and refresh rates than D-Sub.
