"480i-1080p upconvert enabled" or
"480i-1080i Upscale Active".And when the scaling of the realta isnt active something like this:
"480p Hqv upconvert impossible.Please check source" or
"720p Hqv upscale invalid.Source must be 480i" or
"480p_upconvert disabled".Something along those lines. Another thing, some user settings to enable/disable various settings, mainly being upscale/deinterlace, with the RealtaHqv.In general, there should be a way to permit the bypass of the realta internal signal processor.They definitely have the capability to implement something like this with a firmware update if enough people call them or email them about this shortcoming.
I don't own this TV, but my understanding from other AVS threads is that since you have a 1080p LCD, you can't be looking at anything other than 1080p on your set. It is therefore implied that realtaHqv is taking the source (480i, 480p, 720p, 1080i o whatever, as indicated in the TV's info display) and always converting it to 1080p. By hook or by crook, scaling, adding letterbox bars, whatever, the TV's processor is must create a 1080p image in order to display it on it LCD.
If my mental model is correct, then, the only time the realtaHqv is *not* doing its anything is when your source is already 1080p. In every other case, some amount of conversion is being performed in the TV's processor. Unfortunately, the TV cannot give you the entire picture (so to speak). It only knows what was presented at it input, not what the original media was. (An exception to this is when it is tuning OTA HD channels.)
Forgive me if this is already well understood. When we have a some media input to a source (DVD player, cable box, satellite tuner, etc) connected to the TV:
media ----> source ----> TV ----> your eyes
we have three possible resolutions. The media resolution (DVD: 480i, cable box: varies by programming, etc), the source output resolution (possibly the same as the media if the source device is/can be configured to "native", though often set to be something else) and the TV's resolution (always 1080p in your case).
With the Syntax's high quality processor, it would seem you'd want the source to do as little conversion as possible to the media resolution, thus allowing the TV to the most. In the case of DVD, you'd want the DVD :
DVD disc --(480i)--> DVD player --(480i)--> TV --(1080p)--> your eyes
This also explains your later issues with you DirectTV box.

Earlier, apparently, you where happy with the results. At that time, possibly, this was happening:
Sat program --(480i)--> Sat Receiver --(480i)--> TV --(1080p)--> your eyes
where the TV was doing all of the conversion and producing a satisfactory result.
I'm unfamiliar with DirectTV H20 settings, but perhaps they where changed from what might have been "Output Native" to something else, "Output 1080i" lets say. So now we have all but lobotomized the TV's scaler:
Sat program --(480i)--> Sat Receiver --(1080i)--> TV --(1080p)--> your eyes
relying instead on what is probably a crap scaler in the H20, producing your unsatisfactory result.
Given the media's resolution is controlled by a third party, in some cases you could have this occurring, yielding a less than optimal result with no work around:
Original material --(480i)--> Sat program --(720p)--> Sat Receiver --(720p)--> TV --(1080p)--> your eyes
This might occur, for instance if the satellite broadcaster "promised" 720p but only had 480i material. I don't know about DirectTV, but I think this sometimes happens on OTA digital stations and cable.
