In case the laptop does not have an HDMI port

Step 1: Connect the image

Prepare an HDMI – VGA converter. This type is currently on the market in many forms: one with one cable available, one that only has an adapter without a cable, … but the usage is similar.

For example, if you buy an adapter that doesn’t have a cable, you have a VGA cable and an HDMI cable ready. Then you use the VGA cable to connect the laptop through the VGA adapter, use the HDMI cable to connect the TV and the adapter via the HDMI port.

Then press the SOURCE, INPUT button (or the button with the arrow…) on the TV remote > Select the data input for the TV as the HDMI port you plugged in.

On the other hand, if you buy an adapter that already has one of the two cables plugged in, just buy the other and connect the same.

Step 2: Connect the audio

The point to note is that the VGA port is a port that only transmits images, not audio. So if you complete the connection step 1, the picture will play on the TV, but the sound will still be on the laptop . If you want the sound to output to the TV, you must connect the audio using an audio cable.

There are 2 common ways to make this connection:

• Method 1: Connect through the white – red Audio Print port on the TV.

To connect, you need to purchase an AV – 3.5 mm cable. The AV head you plug into the AUDIO IN port on the TV in accordance with the red and white colors, the 3.5 mm head you plug into the headphone jack on the laptop.

• Method 2: Connect via 3.5 PC Audio jack on the TV.

This is the port that allows you to receive audio from the laptop. On this port, there will usually be the word AUDIO IN or the word AUDIO with the arrow icon going into the circle.

To connect, you need to purchase a 3.5 mm cable. One end of the cable plugs into the PC AUDIO IN port on the TV, the other end into the headphone jack on the laptop.
