There are two separate issues here :
1. The X server is not reporting a mode which you feel your TV can support
2. When you try to switch modes to 1920x540 via KDE something goes wrong and there's no record in the log
Using xrandr will immediately help with #2. You can also use xrandr to add a mode but you'll need the same timing info as if you were adding a modeline in xorg.conf.
