How To Change your PS3 from 720 to 1080p - YouTube

hi there, you did not mention what you are actually watching on the bluray player, i.e is it 720p or 1080p ?. Also, how do you know it is actually 1080p from your cable box ?. And what is the model number of your TV ?.

Most likelly it is your DVR that has a problem. Their are a lot of issues with those DVR's from the cable or satellite companies. I would recomend swapping it out.

If it's the first time using your PS3, use the composite cables that came with it. Turn on the PS3 go to video settings and switch the input to HDMI. After you've switched to HDMI, turn the PS3 off and connect your HDMI cable, go back to video settings and change the resolution to 1080p. If this isn't the first time you've used HDMI for your PS3, make sure your T.V. is on the correct input. If the T.V. is on the correct input, try switching the HDMI cable to a different input. If that doesn't work try using a different HDMI cable, testing different HDMI connections if you're still getting the black screen. If none of those work then it's probably a problem with the PS3, but just to make sure try plugging something else with HDMI to see if that works. If another HDMI device works, then it's your PS3, if it doesn't then it could be a problem with your HDMI connections on the T.V.

What are the specs on your emerson, does it support 1080p? Make sure you have the right settings on your ps3. If your emerson supports 720p and 1080i then it will not give you a 1080p picture and you might run into issues.

Thats the highest setting, for component, that TV will show. it really is that simple. You would need HDMI connector to possibly go any higher. but I think you will find it is the TV.

whats the p rating on your 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.

depend if your TV dos 720 & 1080 ill look into this more for ill get back 2 u soon

get a component cable
