if You use the maximum LCD's resolution and frequency, and everything is sharp, then it's probably setup correctly... but you can try. new monitors will tell you, that you are out of bounds, if you enter too high or too low values... simply enter higher maximum bandwidth/pixelclock, and use slider to increase it's value, when the picture will disappear, you got probably out of bounds... this way you can find all the values for Hz, kHz, MHz...
