I have the sharpness of my display turned to 50 which is the setting for movies as recommended by you in an earlier discussion. I have tried turning it lower and turning the detail enhance level on the AVM higher, but this did not provide good results. Currently, the AVM detail is set to 15 for my satellite input. I've played around with this a bit and this setting in combination with the 50 setting on my display seems to provide the best results. I've heard about providers cramming too much information, so perhaps that is what is causing it especially where I don't think I've noticed it while playing DVD's. It just seems odd that I never noticed it prior to getting the AVM. What is kind of reminds me of as well is a slow refresh rate on a fixed pixel display. I'm not sure if that makes sense or not.
I also used Digital Video Essentials and Monster Cables ISF calibration disk in an attempt to set things up properly.
Because some of the networks broadcast in 720p and others in 1080i, I chose to set my satellite recivers output at 720p. I suppose it is 6 for one and half dozen for the other in this case unless you think setting it at 1080i is my better option?
Thanks,
ps, I know the display is capable of stunning pictures, especially evident while watching DVD's so it should be able to produce at least equal quality pictures through HD. (Unless, like you say it is due to the provider)
Bluemark81,
If your satellite receiver is not able to switch output resolutions automatically according to what's coming in on each channel, my recommendation would be that you set it to 1080i output. Most HDTV is 1080i and you want the receiver to do as little as possible to the signal before passing it to the Anthem, so selecting 1080i output means you get your "best" viewing on 1080i HDTV channels.
If your satellite receiver allows for an easy manual switch of resolutions while watching, then the ideal would be for you to change its output to 480i when watching SDTV channels, and to 720p when watching those few channels that broadcast HDTV in 720p -- generally for sports programming, and then back to 1080i for other HDTV.
If your receiver can't be set to send 480i to the Anthem for SDTV, then using 480p is better for SDTV than using either 720p or 1080i. That means the receiver will be doing the de-interlacing -- probably not all that well -- but it won't be doing any scaling.
The de-interlacers in these boxes are generally pretty bad, and the scalers downright awful.
---------------------------------------------------
Dish does not bit-starve its HDTV to the degree that DirecTV does, but it still does to some degree. So you WILL see some artifacts when there is high motion since the video compression scheme used to encode these images isn't being given enough bits to handle all the changes. However I suspect that setting the receiver to 720p as you've done, and thus forcing it to scale 1080i HDTV channels down to 720p, may be causing even more problems for you.
---------------------------------------------------
In addition I suspect your Sharpness and Detail Enhance settings are still too high.
My recommendation would be that you turn Detail Enhance in the Anthem all the way down to 0 -- its factory default setting. While you are at it, any detail enhance or sharpness setting in your DVD player should also be turned OFF.
Now first make sure your Brightness and Contrast are reasonably set. If they are not perfect that's not a problem, but if they are way off, setting Sharpness properly will be difficult. Contrast too high, for example, can cause "blooming" of whites which will screw up the appearance of the contrasty edges you need to look at when adjusting Sharpness on your TV.
Also make sure any "SVM" or "Velocity Modulation" feature on your TV is turned OFF. SVM will cause vertical black and white lines to not have the same width. Leave SVM off permanently. It is an abomination.
Then also turn Sharpness ALL the way down on your TV. Now go to your calibration DVD's sharpness setting test chart and rapidly run Sharpness up and down on your TV. What you are looking for is white halos on either side of isolated vertical black lines in the pattern. Sometimes it is easier to see the halos at the ends of horizontal black lines. Keep running Sharpness up and down on your TV until you begin to see and recognize these halos. Do not worry at this point about the lines appearing fuzzy when you run Sharpness all the way down. Just look for those halos until you are confident you know what I mean by them.
[Note: If your DVD calibration disc test chart has kind of a zebra stripe pattern of repeated vertical black and white lines in some portion, along with instructions to adjust Sharpness to even out that pattern all the way from the wider to the thinner lines, JUST IGNORE THAT FOR NOW! Find vertical black lines that are isolated away from other stuff so that you see just that line against the gray background. Concentrate on those isolated, vertical black lines exclusively.]
Once you have learned to recognize the halos, now turn Sharpness all the way down again and then SLOWLY raise it. What you want to do is sharpen up the fuzzy vertical lines in the test chart but without even the SLIGHTEST HINT of the halos re-appearing. Record the setting you think is right.
Now run Sharpness up and down rapidly again until you feel comfortable again that you know what the halos look like when they are present, and then set Sharpness ABOVE the point where halos are clearly present and SLOWLY lower Sharpness until the halos COMPLETELY disappear. Compare your result coming up from below with your result coming down from above. Iterate a bit until you are comfortable that you have found the one, best Sharpness setting in your TV where the vertical lines are as sharp as possible without even the slightest hint of halo showing.
That's the correct Sharpness setting. Typically that will be in the lower third of the range of Sharpness settings offered by your TV. For some TVs, the correct Sharpness setting may be almost all the way down.
Again, all this should be done with the Anthem's Detail Enhance turned all the way down to 0. Leave it at 0. You should not need to use this Anthem adjustment with a display device (like your TV) that has its own adjustment.
-------------------------------------------------------------
The resulting image may appear too soft at first. Give yourself time to get used to it.
That said, I think the big win for you will be changing your satellite box to 1080i output for most of your HDTV watching.
