According EE class A requirement we need to set default from 300-350 nits to 210-245 nits , but it may cause CDE4302 has lower brightness. 

Here are the testing equipment and method for testing the 350 nits spec.

1. Using KONICAMINOLTA CA-210 or CA-310 pattern generator and color meter to get the following testing result.

2. Increase the brightness of the machine from the current 70 to 100. Using the white screen to test the brightness will be much brighter. According to the difference of the panel itself, the brightness is between 300-400.
