Hi I have just set up my new Pi B with Wheezy Linux and find that the HDMI output gives the correct picture on my 32" tv, but when I use the RCA composite video output to feed the 15" LCDtv with 1024X768 resolution which I want to use on a permanent basis the picture is incorrectly sized and does not show the top and bottom of the raspberry logo and the text is faint. Is there a file somewhere that needs changing to give the correct size? 
Hi thanks for your reply. iI have changed the config.txt file as detailed in these articles but it does not change my screen.

Yes, I believe that there is a resolution limit on the RCA socket output. See this article: http://en.wikipedia.org/wiki/List_of_display_interfaces which says the maximum resolution with RCA composite is 720x576i@50Hz or 720x480i@ ~60hz.
So the 1024x768 resolution is not possible on the RCA connector. (as far as I know).
