Mode: Cinema

Picture: 75
Brightness: 43
Color:35

Color Temp: Warm
Sharpness: 0
Black Level: Light
All NR: off

B: -8.2%

I have updated the recommended settings based on an HDMI, High-definition input. These are a little different (especially the Color setting) from my original post when I was using test patterns from a Standard Definition component input.

It turns out that the observation I made before about the red primary being so accurate in the Standard mode was only part of the story. What I saw was the result of 3 variables: Standard mode AND component input AND SD (480i/p) resolution. 720p and 1080i (component and HDMI) and 480p HDMI are essentially the same whether in Standard or Cinema. All show an oversaturated red primary, even with the Color control turned down to get reasonably good decoding. Odd.

Also, like a lot of modern digital displays, this one definitely performs the best with the HDMI input. With component inputing a 1080i signal, a 37.1MHz multiburst shows very rolled off luma resolution and non-existent chroma response. In comparison, the HDMI response looks crisp and clean. I also noticed significant color bleeding from test patterns on component inputs.

This is too bad. There is no technical reason why a display's component input can't offer perfect response with 1080i signals, but manufacturers just aren't making much effort.

I also finally checked the HD processing. Not perfect, but quite good. I set my Blu-ray player to output 1080i and used the Silicon Optics Blu-ray Benchmark disc for the test. I saw almost no jaggies and good detail. The Panny correctly deinterlaced 1080i video-based material, retaining the full resolution of the original source. However, it did NOT correctly deinterlace film-based material, discarding some of the available resolution. On the other hand, it did correctly apply 3/2 pulldown. The real-world implications of this are not serious, since Blu-ray stores the data in 1080p format on the disc anyway.

I checked the HD processing with actual program material using my favorite torture test Blu-ray disc, Mission Impossible III. The Vatican wall in chapter 7 showed just a hint of moire distortion in the lower right-hand corner and the staircase scene at the beginning of chapter 8 showed a small amount of line twitter. All in all, this was pretty good performance.

I am not particularly sensitive to motion judder inherent in the 3/2 processing necessary to display 24 fps film-based material in 1080p/60 format, so I did not test its 1080p/24 processing ability.

BTW, tests and tech talk aside, this plasma provides a VERY good image. The detail and depth are stunning and post-calibration the color is very convincing, though the oversaturated red primary gives skin tones a somewhat rosy appearance that was often, though not always, evident. Perhaps the most telling testimonial I can offer concerns a very high quality CRT that I love. I was amazed to find that it is now difficult to watch because the Panny plasma's detail and that "looking-through-a-window" experience is so much more compelling. This is true even for SD material where the CRT should have a natural advantage. The CRT looks dull and fuzzy in comparison. I have not seen any motion artifacts or problems with white field uniformity (perfect on my unit) that some others have complained of.

Settings for HDMI, High Definition

Mode: Cinema
Picture: 80
Brightness: 42
Color: 41
Hue: -2
As far as I can tell, the Sharpness control has no effect on the image when using the HDMI input.

i used it to get the th-50pz85u. not sure about the others. as usual.... be careful, load silver bullets, etc, etc....you know the drill by now.

Nope, this is the service manual with info on the service menu, rgb cuts, drv, for greyscale calib, etc. Some Ppl in the 77u thread have been posting these settings along with their user settings, hope ppl here start too eventually.

see example - http://www.avsforum.com/avs-vb/showt...6#post13481066

If you throw up a multi-burst pattern (series of vertical lines with gradually narrowing widths) and adjust sharpness up you will start to see white borders behind them and the very thin lines can start to shimmer if you turn sharpness up too high.

I'm going to run the DVD over night and see if it gets better with time.

4. What is the "break-in" period and what should I do during the break-in period to minimize any risk of image retention? When your plasma TV is initially installed, the first 100 hours of use is known as the "break-in period." During this time, to minimize any risk of image retention, you should:

1. Make sure the plasma TV is in a viewing mode (aspect ratio) that completely fills the screen. The panel is shipped in this condition, in what is called the "Just" mode.
2. Turn down the Picture setting (in the Picture menu) to +0 [note: on the 85U 0=50].
3. Briefly engage the 4:3 mode and confirm the side bars are set to "Mid", or "Bright". This can be adjusted in the Set Up menu.
4. Always return the display mode that fills the screen (such as Just, Zoom, Full, or H-FILL).
5. Try not to view channels with stationary backgrounds or logos for extended periods of time.
6. Avoid extended display of static images (video games, computer images, DVD title screens, etc.).

I saw one in BB hanging and the shelf just looked out of place. However, on the pedestal it just blends right in and I rather like how it looks. I really like how the sides of the TV taper and curve back slightly. Panasonic says this is supposed to make it seem thinner and I think it actually works.

I only have one complaint. I'm still seeing a slight greenish tint throughout the middle of the screen with reddish around the edges when there's a light color or white screen. This is being discussed further at http://www.avsforum.com/avs-vb/showt...9#post13467429

I have a tech coming tomorrow to look at it. We'll see what he has to say. It's really not a problem during normal viewing. I see it when I'm running the break-in DVD, when the TiVo displays a solid gray screen while changing channels etc, or if the programing has a large light color or white on the screen. I'm still not sure if it's just something that some sets have. I can see it in some degree and in different patterns on about every Panasonic plasma I looked at in the store. Still undecided as to whether I should exchange it. I should know more tomorrow.

In conclusion, I think this TV is simply excellent and a great TV for the price especially.
