Fixed the accuracy of backlight level in PWM and D/A mode. (It was found that the backlight level is not linear to the percentage of the level and different ranges for different PWM frequency or in D/A mode, also the system backlight level control function was replaced by own method) 2. Add a RS-232 Backlight Status Query command - 0xe1 "S" or 0xe1 "s".

The controller will set the preferred timing based off the dip switch setting selection, but also be able to go higher to 1920x1200. For example, if the panel is a 1024x768 and the dip switch setting are set for 1024x768. The preferred EDID resolution should be 1024x768. It should also have the capability to set the max resolution to 1920x1200. Remark: This function supports on HDMI and Display port only (2) Bug fixed on overflow the RS-232 command Bare PCB: 017270002-3; P/N 417270122-3 BIOS: U10, V1.30.00 (Flash PCT25VF040)(changed) U13, V0.40 (ARGB DDC, 24C02)(no change) U12, V0.40 (HDMI DDC, 24C02) (changed, 1920x1200, CS= 45,48) U20, V0.40 (Display Port DDC, 24C02) (changed, 1920x1200, CS= 45,48) Page 1 of 2 ECN# 870689642 PRODUCT REVISION RECORD Prepared by: DV-HK Page 2 of 2 Date: 21 April 2017
