I recently purchased the Panasonic TH-50PZ800U, and let me tell you it is awesome. I am however having a problem with one of the channels. I currently have an HD antenna and when I tune in to NBC-HD I notice that there is a yellow line on the far left hand side that runs from the top to the bottom of the screen. This problem doesn't occur when watching movies or other HD channels. I don't know if it is my TV or if it is the channel. I thought I would ask someone that knows more about this unit than I do. There is still time for me to return the TV, what should I do?

In the picture menu, go to advanced picture controls at the bottom. Change HD Size from 2 to 1. Problem should be solved.

This issue happens because not all broadcast material is full 1920x1080 resolution. If it's not, there will be lines on one or more picture edges. Save Size 2 for Blu-Ray movies and for those broadcasts and games which you really want to enjoy at maximum quality and which you know (from trying it) are at proper HD resolution.


Size 2 is the optimal quality, but needs a proper signal from your source. This problem is in the signal, not the TV. Size 1 zooms by 5% to avoid this problem.

Thanks Johnnylighton, problem solved. Now each time I use my blu-ray player do I have to switch it back to Size 2 for the best picture quality?

I would use HD Size 2 on your Blu-Ray if it doesn't have the extraneous lines.


As to whether you have to change the setting when you switch sources each time, I don't know the answer to that. Can you do a test to see if your chosen picture mode (I'm assuming it's THX) maintains your specific settings for each of your sources, and report back?


E.g., you set your TV tuner for THX, HD Size 1, and your Blu-Ray for THX, HD Size 2. When you switch back and forth between sources, does it remember the HD Size settings?

 

[Mattsbay18]

No it doesn't remember the HD Size setting. When I changed the Blu-Ray setting to HD Size 2 it changed the TV tuner setting to Size 2 as well.

 

[johnnylighton]

Oh well, that's too bad. Thanks for the test results, though!


Personally, I would change to Size 2 when sitting down to a Blu-Ray movie and change back for other viewing. But that assumes I can see the difference, and I haven't bought a Blu-Ray player yet. (I'm not a gamer so I'm not planning to go the PS3 route.)
