Need help with laptop and tv display

[Roy Dennis]

Sorry I did not answer you earlier but was doing my own show last night.
Just an after thought, could it be to do with the settings on the TV itself, you usually have somewhere on the TV to adjust for wide screen, 4.3 zoom or show black bars top bottom and sides, my own TV allows for 4.3 or 16.9 while connected to laptop or do you have PIP selected (Picture in Picture) ?
Perhaps having the wrong aspect selected on TV is causing this to alter your laptop display.

You never did tell us how you were connecting to your laptop to the external, is it via s-video, rca video, HDMI, VGA lead or through some converter box ?
I should think connecting through an RCA video connection less likely to change your laptop picture when attaching it.
