How to change an hdtv in sd mode to get a hd picture?

Posted on 16. Nov, 2009 by admin in HDTV

Hello there! If you are new here, you might want to subscribe to the RSS feed for updates on this topic.

I recently bought a 37″ Vizio LCD HDTV. However, when I press info to see the show it says the show then 480i SD. But I have an HD Cable Box and everything. How do I make it so I have an HD picture instead of an SD picture?

The KINDLE…See what all the fuss is about!

You have to make sure you’re subscribed to HD service through your cable company, and that you’re actually watching an HD channel. An HDTV and HD cable box do not convert standard definition programming to HD.

you have to set your TV to 480i to make that work correctly.

Need more info: Is the connection between the TV and cable box an HDMI or 3 component video cables? Finally, is the channel an HD channel? Depending on service, you may only get 5 to 20 HD channels out of the hundreds you may be getting via cable/satellite.

FIRST, you NEED to check your cable box….make sure in the menu that it’s set to OUTPUT a 1080 signal…..if it’s set for 480, that’s all it will deliver to your TV set.

The TV itself is automatic….no settings in your TV to adjust.

Now, YOU NEED to use either an HDMI cable or a COMPONENT cable to get HD. You can’t use your standard 3-wire cables to get HD.

Then tune your box to an HD station like Discovery HD…
