    You mean like Best Buy? :lol:

    The one here has over 80 HD units on display, and I suspect not one of them is calibrated correctly. Out of the box they come, and up on the wall they go... :D

    But seriously...you are correct. Even a $30 HD calibration DVD can get you pretty solid results...if the $400 is out of the budget.

    I experimented several dozen times and I always return to native on, if it matters or not I am convinced is the best way to go.

    If I have a 1080P Samsung Display Device and I Check my DVR's Resolution with only 720P, 1080I and 1080P Checked with Native On, would that work better than Deselecting 480I, 480P & 720P and letting the DVR Scale/Deinterlace everything up to 1080I and then let the Samsung Display Deinterlace the signal to 1080P?

    I believe that the artifacts around static parts of the iamge are due to the mpeg4 compression or from the source and no calibration can help with that problem. Having said that if the TV is oversharpening then.....

    Calibration can help with brightness, tint and color saturation for example and it could help if what you are seeing is from the TV itself oversharpening the image.

    So Calibration may or may not help.

    Why not go to the settings and see if there is a sharpen control and turn it down as well as adjust the other settings to see.

    Great info by everyone... thanks for the replies!

    I have done some testing since I originally started this thread and I can say that in my case, setting Native On results in a better quality picture for both SD and HD.

    So how do you folks calibrate for D*? I have a couple of DVDs like Avia and GetGray but they use a different input to the TV. I have scheduled to record the HDNet Test Patterns which I thought would be good to use since they are the same source and input.

    This is a great thread! I was just looking at this very feature this morning as I got a new LED-LCD TV for xmas. I would love to put native on, but when I change channels the TV takes a couple of seconds to switch each time and its really annoying!:D

    I couldn't locate the exact manual for carillon's Sharp, but if it has adjustments comparable to the page attached from a Sharp LC-52LE810UN, I'd also look at the settings like "motion enhancement", "active contrast", "digital noise reduction", and "3d YC". They all look like they have the potential to affect PQ, either for good or bad. E.g., it says: "Motion Enhancement" may cause image noise. If this occurs, turn the function "Off"

    You have a Sharp I believe you said...Go to the DirecTv input, Toggle your video until you get to the USER (not Vivid or Standard, etc) and go into your menu, go to picture, write down all the settings. Then go to advanced, and for each menu, write down all the settings.
    Then enter in these settings. These are for a 46" sharp, but should work for you. If not, just restore your previous settings with RESET, or reenter your settings from where you wrote them down, if you have changed any prior to doing this. If they changed the menus, then maybe someone with a calibrated set newer than mine can post their settings.

    I keep native off & 1080i/1080p checked.

    The picture is only slightly better with native on but its not worth it because of the annoyingly longer channel tune in time.

    If i just wanted the best pic i would get fios but they have drawbacks too.


    edit:
    oops didnt mean 720p.

    Which means if you don't manually change the resolution, it stays at the last resolution. Might as well leave it to the same as your TV's native is then.

    How is it— and is it measurable—[FIOS]- better than DirecTV's picture?

    It is somewhat better but again its up to the viewer to decide what is measureable.

    Some peeps cant even see that directv is better than dish so.

    Indeed they have! In the hands of a knowledgeable technician with the proper equipment it would appear they could dial in the calibration with all that control. For me, I'm probably just going to reset everything to default values and use the HDNet Test Patterns to so basic calibration.

    Can you be in any way specific? Can you not estimate that it is x% sharper, y% less artifacting, or whatever?? Or cite something that does?

    I just got a new Panasonic 50" 3D Plasma (nice gift from our kids for holiday + 45th anniv :) ) to replace our 5yr old NEC PDP which died. So I decided to try Native ON with my HR20-100. It was horribly slow switching on the OLD set but I was pleasantly surprised that it was almost instantaneous switching with the HR20-100 and new Panny.

    Today DirecTV replaced the HR20-100 with an HR22-100 because the HR20-100 didn't support 3D and the "native" channel switching is like 10x SLOWER on the HR22. I went back to the HR20-100 again and it was back to "fast." I thought it was the old TV that was slow but now it seems either the HR20-100 is way faster then the HR22-100 in "native channel switching" or my HR22-100 is defective which I doubt because it works flawlessly in every other way.

    Those Panny 3D sets are outrageously good in 2D. I'm gonna buy one just for that reason. One of these days, when the prices drop.
