In an era dominated by HDMI and other digital connections, the venerable VGA (Video Graphics Array) interface remains a reliable method for transmitting video signals. Although it's an analog technology originating from the late 1980s, many desktop computers and TVs still come equipped with VGA ports. This enduring standard can be particularly useful for those looking to connect their desktop computer to a TV without an HDMI port, whether it's for streaming videos, browsing the web on a larger screen, or transforming the TV into an extended or mirrored monitor for work. Here's a comprehensive guide on how to achieve this connection using a VGA cable.
Understanding VGA Technology
VGA carries an analog video signal that supports various resolutions, though it's most commonly associated with a maximum resolution of 640x480 pixels in its original implementation. Modern versions can support much higher resolutions. It's worth noting that VGA transmits video signals only, so if you're looking to transmit audio as well, you'll need a separate solution, which will be covered later in this guide.
What You'll Need
A VGA Cable: Ensure it's long enough to reach from your desktop computer to your TV without being overly stretched.

Step 2: Connect the VGA Cable
Take one end of the VGA cable and plug it into the VGA port on your desktop computer. It's usually marked with "VGA" or symbolized with a display icon and colored blue. Secure the connection by tightening the screws on either side of the VGA connector. Repeat this process with the other end of the VGA cable, connecting it to the VGA port on your TV and securing it similarly.
Step 3: Connecting Audio (If Required)
If you want to transfer audio along with the video, take your 3.5mm audio cable and plug one end into the headphone jack or audio out port on your computer. Plug the other end into the audio input jack associated with the VGA input on your TV. The labeling and availability of this port can vary between models, so refer to your TV's manual if necessary.
Step 4: Power On and Select the Correct Input
Once all cables are securely connected, power on your desktop computer and TV. Use your TV remote to navigate to the input selection menu and choose the VGA input option. It may be labeled as "PC," "Computer," "VGA," or something similar.
Step 5: Adjusting the Display Settings on Your Computer
After your computer boots, it should automatically detect the TV and extend your desktop onto it. If the display doesn't appear as expected, you might need to adjust the settings manually:

- Windows: Right-click on the desktop and select "Display settings." Here, you can adjust whether the TV mirrors your main display or acts as an extension. You can also adjust the resolution here, which should match the native resolution of your TV for the best quality.
- MacOS: Open System Preferences > Displays. Click on the "Arrangement" tab to set up mirror mode or extend your desktop. Use the "Display" tab to adjust the resolution.
Step 6: Enjoy Your Setup
With everything connected and configured, you're now ready to enjoy your desktop computer's content on your TV screen. Whether it's for work or leisure, a VGA connection can breathe new life into older technology, proving that sometimes, older standards still have their place in our modern digital world.
Conclusion
Connecting your desktop computer to a TV using a VGA cable is a straightforward process that opens up numerous possibilities for media consumption, gaming, or extending your workspace. While it may lack the convenience of modern digital standards like HDMI, the ubiquity and simplicity of VGA make it a valuable option for those looking to utilize available technology without requiring significant upgrades or investments.
