Hi All, Apologies if this has been asked numerous times, I must confess to flicking through a few previous threads but couldn't immediately see what I was looking for.

I have a KD-49X8305C and a HT-CT80 and a BDP-S4500 that all work OK together whilst viewing TV using the TV's internal YouView (YV) receiver (Digital TV channel). However I also have a BT TV UHD YouView box plugged into HDMI1 and this is what I use mainly as I want to be able to use the features of the STB. However I have two main issues.

1. When viewing the input from the TV's internal tuner I have full control over all Picture Settings (Wide Zoom, Normal, Full, Zoom, etc), however when watching input from HDMI1 I can't control any Picture settings at all & I get a message saying "Not available with current signal". I have also noticed that ALL HDMI input settings are defaulted to Wide Zoom, which is clearly not ideal from an image quality perspective, as whilst the image appears slightly larger, I am assuming it is effectively stretching & cropping the image :(.

2. On some channels received via the HDMI1 port via the BT UHD YV STB I get either a series of white dashes or a flickering in the top row of pixels of the screen. That is why I was looking at Picture Settings to see if I could throw this top line off the screen.

Here are some photos to show what I'm seeing:

With both the TV tuner (referred to as “Digital TV” in the photos) and the BT YV box (referred to as “HDMI 1” in the photos) both set to Channel 101 (BBC One HD):

Starting with the Digital TV Options

You can see the Bravia settings available to me, and you can see that the Wide Mode setting, which seems to automatically default to whatever type of signal it is receiving per channel, is set to “Full” mode. The photo below shows the options that this could have selected, or I could over-ride if I chose to:

Now, if I change the input to the TV to be HDMI1 and do the same, this is what I get:

You can clearly see that the TV has automatically selected “Wide Zoom” mode, which explains why people look “bigger” when I’m watching from the BT YV box. However, when I try and change this option I get the following message “Not available with current signal”:

Now, for my next experiment!

If I set both the TV tuner and the BT YV box to a channel where I know I have “flickering” at the top of the screen, like (Drama - Channel 20).

I start with viewing the options set for the TV Tuner, and this is what I see (you will see Wide Mode set to “Wide Zoom” by default and the picture fills the whole of the TV screen:

However, when I switch the TV to the HDMI1 port, this is what I see (you will see the Wide Mode is set to “Wide Zoom” by default, but this time the picture is only showing in a small window in the centre of the screen and is not “stretched” at all.

If I try and adjust ANY of the Picture settings when watching any of the HDMI input’s I get the following message (Not Available with Current Signal):

Any help, most appreciated as I am totally baffled, and only want to a) get the flickering top line to go away when I am watching the channels afected whilst watching from my BT YV box and the ability to control Picture Settings on my HDMI ports - it's not too much to ask of a load of new Sony kit, surely?
