Just got my gp2x today. While playing with the LCD setting I found there is no difference in any of the brightness/contrast/gamma no matter how I adjust the LCD setting bar (left most or right most, no difference). Is this normal?
Do you not notice anything chancing? Wavy lines?
He probaly has an MKII which does not have the scanline problems like the MKI. If you have an MKI then your stick will not be concave. For an MKI it is best to set it to "4" with the left most being 1.
