Hi,

I discoved a bug or a very strange behaviour on my 58PFL9955. If I watch digital TV and have chosen the zoom mode "unscaled" I can see on the left and right sides of the video more content than in the other zoom modes. Or: in all zoom modes (different from "unscaled") I can see less video information than available!

Unscaled:

Zoom mode "16:9":

In the above two pictures you can see, that in the first one (unscaled) one can see more image content on the left side of the broadcaster logo. On the second image ("16:9" zoom mode) one can see less information.

Both together:

I could also verify this behaviour when I play a Blu-ray from my BDP9600 (via HDMI 1 ARC).

Why is image content missing on the left and right sides in all zoom modes?

Hi,

after some comments in my blog it seem that this is an old relict from the analog age and it is called Overscan (http://en.wikipedia.org/wiki/Overscan).

What I don't understand is why it is necessary to cut these parts off in the digital age - especially with Blu-ray content!

Hi Toengel,

assuming the 58PFL9955 is similar to the 32PFL9705 (just a LOT BIGGER! ;) ), you can fix this by setting the Zoom Mode to Auto-Zoom and the Edge Size to 0.
Does that solve your problem?...

Hi,

yeah - I found out, that the edge size was set to 9 - extremly to high... That fixed it...
