3 The variance of color coordinate via R,G,B gains:

	x	Y
R ↓	X ↓	-
G ↓	-	y ↓
B ↓	X ↑	y ↑

4.Adjust 6500K temperature color by changing Gamma-Rgain, Ggain, and Bgain.

5.Open Factory OSD and set the factory default value :

user>setup>white	C0	C1(5400k	C2(6500k	C3(7500k
Gamma-Rgain	512	512	512	512
Gamma-Ggain	512	412	467	479
Gamma-Bgain	512	398	452	490

9.Follow step 1 to 8 to adjust 5400K, 7500K color temperature.

10.For auto-alignment, use Command Y31/Y32/Y33 to save 5400K/6500K/7500K temperature

11.For auto alignment, use Command to reset Temp4 color temp to 6500K
