Hi.

I'm wondering if anyone else is experiencing coloured dots with the new feeds of TV1 & Tv2 since they changed over at the start of the month?

The coloured dots only apper with the non-HD feeds. HD programs and they disappear.
1 white dot in the extreme top left. 1 red and green dot in the extreme bottom right.
All other channels are clear.

My TV is a Panasonic TH-42PZ850AZ

I have yet to contact Sky about this.
Been on holiday until now and I thought I'd see if I was the only one 1st.

Thanks.

Have you got overscan turned on or off on your tellie? If it is 'off' then dots may be the info carried at the edge of the picture that is not normally seen.

Thanks Dingbatt. Turning the overscan on pushed/zoomed the picture slightly out. The dots are now off screen.

Not to get too far off topic but is it normal to have the overscan switched on?

For tv yes it is. By default all tv's use overscan.

Yes as garvani says traditionally TVs use overscan so you don't see the ragged edge. However I operate my PZ850 with the overscan off in the hope that I get 1x1 pixel mapping when watching a 1920x1080 HD source.

So, when I watch my Blueray movies, I'd best try to remember to switch it back to "off" to experience the full effect of the movie and then back "on" for normal TV viewing.

ummm....seems a hassle. Best not try and explain that step to the better half. She's just got the swing of the multi-remote vs all the toys that are plugged into the TV. LOL

The use of overscan makes having a panel the same res as the source pointless since its still going thru the image mangler in the TV...

If you use a PC type screen they typically have no overscan options so this crap on the edge of the picture is a real pain with digital.

I just leave the overscan off all the time. It doesn't take long before you ignore the occasional tic or dot around the periphery.
