Hi guys,

I have been using a laptop as a video source for my beovsion 8-40 for about a year. I have noticed banding in a lot of videos, have just been watching netflix and nothins else and assumed it was due to netflix compression, recently played a bluray on the laptop and noticed the same banding on the TV in color gradients. Fired up the laptops display and the banding is not there, tried a different monitor hooked to the laptop thinking its HDMI output was maybe limited to 16 bit color. On the internal display and an external monitor there is no banding. Also checked the settings in windows and it is putting out in 32 bit when hooked to the beovision, but it looks like 16 bit. Is the display in the beovision 8-40  really only 16bit or is there a setting in the service menu im missing?

What it should look like

so I just hooked up to the TV with VGA and the banding is not there Getting the full color depth, so it seems to be a problem or limitation on the TVs digital signal chain. Any firmware updates available?
