5.3.2. How to change the “Brightness” setting.

The following is a sample of procedures to control the monitor, these are examples of "Get

parameter", "Set parameter" and "Save current settings".

Step 1. The controller requests the Monitor to reply with the current brightness setting and

capability to support this operation. (Get parameter)

Notice

(1) CURSOURCE Setting Value
AV1:0, AV2:1, AV3:2, COMP1:6, DVI:9, DS UB:10

(2) MAX_ILLUMINANCE Settings
Setting Value = Ambient Level (by LUX) / 100
Ex) Desired Ambient is 10000 Lux, Setting is 100 (= 10000 / 100)

(3) MIN_ILLUMINACE Settings
Setting Value = Ambient Level (by LUX) / 10
Ex) Desired Ambient is 200 Lux, Setting is 20 (= 200 / 10)

(4) TEMP_THRESHOLD Settings
Setting Value = Desired temperture(by Celsius) x 2 + 60

Ex) Desired temperature is 60℃, Setting is 180 (= 60 x 2 + 60)

(5) TEMP_HYSTERESIS Settings
Setting Value = Desired Hysteresis(by Celsius) x 2

Ex) Desired Hysteresis is 2℃, Setting is 4 (= 2 x 2)
