I had no idea until now that this query had moved over here.
To the best of my knowledge we've had just one poster (MARKALSTON) in the Anthem D2/AVM50 "tweaking" thread (cited above) who has posted his video setup for getting "native" 1366x768 into his Panasonic from the Anthem Statement D2. Here's his post from back in December with the settings he used:http://www.avsforum.com/avs-vb/showt...&&#post9081443
There was no follow-up, but based on some posts he made in other threads later, it looks to me like he had success with these settings. In any event, this gives you an idea of the sort of flexibility available in the D2.
These are settings that are entered into the D2 as a "custom" video resolution, using an Anthem supplied, Windows PC program called Live Video Settings Editor. The "custom" resolution then becomes available to select as an output resolution in the D2's own user interface -- in addition to the various built in resolutions Anthem provides. Apparently as of December, 2006, the built-in 1366x768 resolution in the D2 didn't match what his particular Panasonic needed, but he was able to derive what he needed as a "custom" resolution from information found in other scaler-related threads -- most likely here.
I don't know if these settings are "perfect" for the Panasonics, but evidently they are at least very close and could be tweaked as necessary.
On the issue of verifying 1:1, here's a link to the complete response I gave Jim E.http://www.avsforum.com/avs-vb/showt...&&#post9744728
A little further down he asked about the DVD player I was using to do this. All very civil and certainly appropriate for that thread.
As I said in that response, I think the D2 would be a better product if it included an easy-to-intepret, edge to edge test chart along the lines of the Avia Pro Pixel Cropping chart.
An image that detects rounding errors such as the one in the Crystalio product would also be nice. The test bar patterns that are in the Anthem now are helpful for left/right edge stuff, but not really fine enough to detect 1 or 2 pixel mismatches. And they can't be used to test the top or bottom of the image.
I'm a big believer in eliminating places where errors can sneak in, and so test charts generated internally by the D2 would certainly be better than having to rely on ANY source device based charts such as from Avia. Once you know you've got the output side set up properly in the D2, THEN is the time to use source based tests to confirm things are also correct on the input side.
That said, D2 software upgrades have already shown steady improvements in their internally generated test charts, so I'm hopeful this will also be on the list.
There are quite a few people actively participating in the D2/AVM50 "tweaking" thread over in the amps/processors forum here -- as evidenced I suppose by the 4K+ posts mentioned above. It's a sufficiently complicated device that we are all learning as we go.
Feel free to chime in over there as well if you'd like!
And Jim E., I hope you didn't feel put off by all the other discussions that were going on at the time you posted your question. It was a good question, and I, for one, am glad you asked it. But it CAN be a bit daunting when there are 12 other continuing discussions going by simultaneously.
Hope this helps!
