1. First and foremost, you need a video cable to make the connection happen. Depending on what format you’re using, you can use an S-Video cable, a VGA cable, or an HDMI cable, the latter two offering the best visual quality.
The simplest and cheapest way of connecting your laptop to your TV, regardless of how old either component is, consists of connecting the laptop’s S-Video port to the TV’s S-Video input.
For a higher quality of visual, a VGA cable used with VGA ports is the way to go. Once again, since VGA is a fairly old format, most laptops and TVs have the port, and its visual quality is better than S-Video’s.
But the best visual quality will come from using an HDMI cable to connect your TV’s HDMI input to your laptop’s DVI or HDMI output. If you can go HDMI to HDMI, you will have about the best visual quality possible.
2. Once you have connected the laptop and TV, you can open "display settings” on your HP laptop and activate TV screen output.
3. Assuming you have a TV that isn’t too old, your next step is to switch to "External Inputs” on the TV’s menu. If you’re connected with HDMI, you must switch the default from "Video 1” to "HDMI”, or else "Video 2” if you’ve made the connection with S-Video or VGA.
And then you should be ready to watch laptop visuals on your big screen. Please note that you may have to adjust the resolution on your TV screen once your HP laptop is connected, as the picture may appear distorted at first.
