Macbook won't recognise maximum resolution of 32" Panasonic HDTV

Question

My white Macbook (2007, 2.13GHz, 2GB RAM) will only output 1400x1050 to my Full HD HDTV (a Panasonic TH-32LZ80, Japanese model). Everything looks stretched... I'd like to use it as I intended at 1920x1080! I tried messing with SwitchresX in a novice way and I succeeded only in getting zero output from the monitor when I tried making a custom 60Hz refresh 1920x1080 resolution
Any help? I've outputted what SwitchresX has to say about my monitor below, not that it seems very useful...

Answer 1

I was connecting it through VGA when I posted the details above. Someone said it would be better to try it through HDMI so I'm just waiting for my Mini DVI-to-HDMI adapter to come through the mail before I give this another bash.
@BSteely: Thanks for your response. The "zero output" I was getting was from the same as the timing parameters above except I put 1920 in the horizontal box and 1080 in the vertical box. Subsequent reading around has led me to believe there was no way it was ever going to be that simple!
