    FAQ [EMB-H81B]

    The EMB-H81B issued a twill problem on 1024x768 18bit LVDS and DP display.
    The EMB-H81B issued a twill problem on LVDS and DP display, the root cause is fault LFP configuration setting of VBIOS. According to the EMB-H81B schematic, the LFP Configuration setting should be setted to eDP(LFP Driven by Int-DisplayPort Encoder). If LFP Configuration setting set to No Local Flat Panel, may be cause to abnormal LVDS timing. The EH81BM26 BIOS has been corrected the LFP Configuration setting, if customer has such display problem, please update the EH81BM26 BIOS.
