How to get 1080 resolutions?

[jphhughes]

THis is my first post on this forum. I just connected the cablevision 8300HDDVR to my new 50" Plasma TV. I was sure when It first came up it was showing a resolution of 1080. Then I made the mistake of reading the manual and did the wizard thing now it only shows 480 resolution. Is there a way to change the resolution back to 1080? The box is currently connected with component cables supplied by Cablevision. Thanks.

ps I did go into the setting menu but did no see anything for that type of setting change.

Did you do the wizard on the cable box/DVR or the display itself?

What is the displays make & model?

EDIT: Is this your cable box?

You can get the user manual here if that is where you ran the wizard and this one I attached is not the correct one. * See pg4

I did the wizard from the cable box, by pressing the Guide and INFO button at the same time. The display is a Panasonic TH-50PX60U Plasma 50" TV. Native Resolution 1366 x 768. Thanks

You should try setting the 8300 to match your display:
720p

Ok thanks to all. The setting is under additional settings (cable Box) and chaning display from fixed to pass-through brought it up to 1080i. Much sharper picture. Regards,
