I have same problem and I opened utouch.cpp and make some change with disp_x_size and disp_y_size

void UTouch::InitTouch(byte orientation)
{
	orient					= orientation;
	_default_orientation	= CAL_S>>31;
	touch_x_left			= (CAL_X>>14) & 0x3FFF;
	touch_x_right			= CAL_X & 0x3FFF;
	touch_y_top				= (CAL_Y>>14) & 0x3FFF;
	touch_y_bottom			= CAL_Y & 0x3FFF;
	//disp_x_size				= (CAL_S>>12) & 0x0FFF;
	//disp_y_size				= CAL_S & 0x0FFF;
	disp_x_size				= 800;
	disp_y_size				= 480;
	prec					= 10;

	pinMode(T_CLK,  OUTPUT);
    pinMode(T_CS,   OUTPUT);
    pinMode(T_DIN,  OUTPUT);
    pinMode(T_DOUT, INPUT);
    pinMode(T_IRQ,  OUTPUT);

	digitalWrite(T_CS,  HIGH);
	digitalWrite(T_CLK, HIGH);
	digitalWrite(T_DIN, HIGH);
	digitalWrite(T_CLK, HIGH);
}
