50hz/60hz signal

[evandl100]

Hi
Excuse my ignorance but please can somebody explain exactly what the real difference is between these two signals for gaming. I've always set the xbox to 60hz and everything seems Ok but have recently read that not many games run at this speed. Is this true? This has come to my attention due to Burnout 3 highlighting the difference during the log on process.
Thanks

Its always better to run at 60hz instead of 50hz as most newe TVs now support 60hz and it provides a smoother gaming experience and better detailed image.
