①. If dark of Gray is deflection, press “CH+/-”and adjust:
1.White.BRoCVBS (vMin=0,vMax=100,vDef=50) →50,
2.White.BBoCVBS (vMin=0,vMax=100,vDef=50) →50,
3.White.BGoCVBS (vMin=0,vMax=100,vDef=50) →50,
②. If sharpness of Gray is deflection, press “CH+/-”and adjust:
4.White.BRgCVBS (vMin=0,vMax=100,vDef=50) →50,
5.White.BBgCVBS (vMin=0,vMax=100,vDef=50) →50,
4). When the Gray is ok, change input signal to white picture at P936, Use colored analysis
instrument Chroma7100 measure colors temperature value of picture at present (whether
Chroma7100 is it given to picture center to pop one's head), On pressing the remote

the projects adjust：
4.White.BRgCVBS (vMin=0,vMax=100,vDef=50) →50,
