Is there a way to enable a native pass-through on the STB?

I've receieved conflicting information about the output resolution of FiOS set top boxes. As I understand it, there is no native resolution pass-through option, so one must choose between 1080i converted to 720p and vice versa. But then I was told by a Verizon rep that all signals are converted to 720p! I would like a qualified Verizon rep to verify if this is true and if there is a way to have the native 1080i and 720p signals pass directly to my TV. If not, i want to know if I should choose 1080i or 720p output for my 720p TV. Thanks.

There is no native passthrough on the STBs.

To set the output, go to...

Menu -> Settings -> Video Settings -> Video Format and select either 720p 16:9 or 1080i 16:9.

As fas as what you should choose, I would try either one and see which one looks best on the HD channels I watch the most. Granted, I don't see much of a difference between the two settings. 

(On a side note, if you don't like stretch-o-vision on your SD channels, set SD Overide to OFF)

Thanks Carl. What you wrote about "not seeing much of a difference between 1080i and 720p" is exactly my point. A Verizon rep told be that all HD signals received by Verizon (720p and 1080i) are converted to 720p. Sounds crazy, I know. But that's the statement I'd like verified by Verizon.

Collective group of employees [edited] agree that it is whatever the provider gives us. If its 1080i and u have it enabled you will get a 1080i picture, If its 720 then 720

I don't understand what this response is trying to say.The end user, the customer, will not see 720p or 1080i depending on how the provider distributes the signal to Verizon, they will see what they have set in their HD STB.

Very clearly the HD STBs that Verizon uses do not pass 720p to the TV for one channel  and 1080i for another. There are four choices for output to the TV: 480i, 480p, 720p, and 1080i. Whichever setting the user chooses is always sent to the TV for the HD channels (the SD Override setting controls the output for the SD channels), and of course to view an HD channel in HD the setting must be 720p or 1080i. You can verify this by viewing, from the TV's menu, what type of signal it is receiving (at least I can, my Sony LCD has an option to display that). Change the STB output, the TV says it is seeing a different input.

I don't know why the OP really cares about how the original signal is handled, there isn't anything he or she can do about it. As a previous responder said, try both settings and see which you like best on your particular TV. FiOS TV has the best picture available anyway IMHO, so I don't understand why anyone would worry about it, you get what you get, and if you don't like what you get, you don't use FiOS - I can't see why anybody wouldn't want to use FiOS, but to each his own .....

Justin, you misunderstood what Tektronic said. He said you will get whatever you have enabled, he meant with your box settings. Also, some people do care about native passthru. Cisco boxes have native passthru. The less processing to your TV, the better the quality of the signal. If you have your box set to 1080i and the signal is 720p, the box has to reprocess it and then your TV has to reprocess it again if it's something other than 1080i.

If I misunderstood what he said, perhaps he should write more clearly {edited}  

I'm sorry, but to me that is absolutely NOT what he said. He said: "it is whatever the provider gives us. If its 1080i and u have it enabled you will get a 1080i picture, If its 720 then 720." Wrong! Whatever Verizon gets, some HD channels will be reprocessed somewhere, from 1080i to 720p or 720p to 1080i, depending on the channel, either in your STB or possibly at some Verizon site. Always! There is no way you can always get what the provider provides to Verizon, unless I guess if you change the setting in your STB every time you change from one channel to another, that might do it if Verizon has not already reprocessed it upstream somewhere.

To me, the much more important thing for FiOS users to understand is that with FiOS, there is no possibility of passthru in the STB, and so what? I understand that some people think that is important, I have seen others say that; but you can't get it on FiOS, so what difference does it make whether you think it is important or not? If that is the most important thing in your TV life, then FiOS is not for you. Seems simple to me, just go to some other TV provider offers passthru if one is available to you and I guess you will be happy.

And for completeness, I have a 40" Sony LCD, native is 768p, I have tried multiple times over 3+ years setting the STB to output 1080i and then 720p, back and forth, viewing multiple channels that are supposedly distributed in both 1080i and 720p, and guess what? My TV displays the best picture with the STB set to output 1080i, on all HD channels (at least the ones I watch). Whether or not the STB and/or the TV is/are making multiple conversions is irrelavant, my picture is better with the STB output set to 1080i. That is why I have always recommended to people that they try it both ways and pick the way that looks best ON THEIR TV.

And after all of this discussion, I bet 99+% of the FiOS TV users don't know about passthru, and more importantly don't care, and this kind of discussion with what I view as unclear posts, about archane subjects, creates confusion I think. I certainly didn't know about it when I got FiOS, I found out about it reading on a couple of forums, found that FiOS didn't offer it, and gee, I kept FiOS in spite of knowing about it.

Yes your dvrs setting is for Max received, If there is a 1080i broadcast, found rarely in sports and vod library, then you will get a 1080i picture. If you set your box is set to 720p then the Max received is 720.

I think you meant to say the MAX delivered not the MAX received.  You receive it at whatever resolution Verizon sends it and the box then processes it to the output resolution you select.  If you select 720p on the STB then 1080i content is downconverted in the STB and if your TV is 1080p it has to be reprocessed by the TV to match the native resolution.  The converse is true if your TV is 720p (accepting 11080i) and you select 1080i on the STB.
