Have TV Questions? Ask a TV Technician
Hello, We can't look up the set from the serial number - I would need the model number, which is on a sticker on the back of the TV. Can you get that please?
A Vizio model number would be something similar to: B550-B1
Are you still with me here?
Another way you can find out if the set is HD or not, is simply look at the back of the TV for any jacks labeled "HDMI". Those are HD jacks by their very nature.
