DisplayConfigX is one of two or three decent tools for making OS X play nice with televisions, with powerful overscan correction settings. However, the documentation is sorely lacking a single sentence that could have saved about 4 hours of my life:
After installing new resolutions and rebooting, you may need to open Display Preferences and re-select the desired resolution.
For whatever reason, the changes I made took hold immediately after rebooting, but the overall display geometry didn't correct itself to compensate. I just couldn't seem to get the settings to do what I expected based on the documented behavior. Switching down to 800x600 and back forced the display geometry to recalibrate.
After about 4 hours of tweaking porches, rebooting, RTFMing, and googling for other folks' run-ins with DisplayConfigX, I figured I should try something different. In hindsight, I feel pretty foolish for not doing it sooner.
At any rate, here are the settings I finally landed on for my Philips 32PF7320A/37 32" LCD TV:

Connection details?
I have a mac mini hooked to my Bravia 40" LCD with a simple SVGA cable and it came up perfectly at 1366x768 the first time, no overscan changes needed. I had a DVI-to-HDMI cable on hand in case I had any problems, but the VGA looked great so I didn't bother.
