comcast moto box????

03-04-2008, 09:20 PM
what should i have my motorola comcast box set to output 720p or 1080i. i have a 1080p set so therefore have been using 1080i (with a lot of issues i wont go into). according to samsungs site
i found this on samsung in troubleshooting. does this make sense to anyone? anyone done this? does it work?

Resolution Settings

All HD cable and satellite boxes have resolution settings you can set to optimize the picture of your TV. This TV works best when it receives a 720p signal. To get the highest quality picture, set the box to output at 720p. If you do not know how to set the resolution, call your cable or satellite provider.

I personlly have my comcast box on 1080i (obviously there is no 1080i) so i thought 1080i would have been better than 720p, am i wrong?

Well, first I'll ask what do you mean there is no 1080i? There are quite a few Comcast stations that are 1080i native resolution. Did you mean there is no 1080P?

Generally fox uses 720p. I don't know the complete breakdown but I do know that the HD assets that are ONDemand are MPEG2 1080i.

Perhaps try watching Ghost Rider or Cars ONDemand (they should be available on starz or encore HD ONDemand comcast nationwide) in both 1080i and 720p settings. Personally on my setup (listed in signature, sounds similar to yours) the 1080i setting provides more clarity however I do tend to notice that on 720p certain channels seem to maintain their crispness a little better during action scenes.(I'm guessing these are channels that broadcast in 720p)

There is no substitution for sitting down and doing personal comparisons because in the end all that really matters is how it looks to you.
