Why won't hd channels be found when I tune my 42 inch baird tv
It depends where you are. Digital has replaced analog signals. If you don't receive channels, ask a friend or neighbours on the situation with their TV. If their hd TV are working properly, then you may have not tuned the TV properly. Have you chacked the Antenna cable? Yes? Then tune it with care and watch what happens. Normally, the TV will show if a signal has been detected. If you have no signal, you need a technician because there are more than one reason this is happening, probably you haven't connected the Antenna cable. Who knows. Again, check the antenna cable, is it lose or wrongly inserted? If you have a small digital TV, connect the antenna to that TV and see if the channels are working. If not, it's probably the cable from the wall socket to the TV (change the cable) or the Antenna cable had been a meal for a rodent on the roof. As I said, who knows?
SOURCE: how do I get from 480 to 1080p on my tv?
1080P is a quality you'll only get with a blue ray quality video. Therefore, you won't get 1080P on cable tv. If your cable provider has HD channels available, you'll be able to get 720 or 1080i quality video (on those channels only). For the best quality, make sure you are using an HDMI cable. Just be sure your cable box supports an HDMI output. Your Vizio definately supports that type of input. If you have a PS3 or alternative blue ray player, you'll be able to watch 1080P.
