Just got a Blu on ebay. Put plenty of games on it but in many of the emulators etc I get a band of lines 2/3rd of the way up the screen. Is there a difference in the blu tft to the ealier FLU units ? I notice that DRMD starts off with these lines on the screen but if I set the screen options to Tiawanese the situation is instantly corrected and my display is clear. Do I need some util to sort this ?
