I just bought a H79, but the service menu shows it is a H77, and my computer also recognize it as a H77! I did not saw H77/h79 before and can not tell the difference. Since the H79 looks identical with H77, I don't know which model I got, maybe I pay the money for H79 but just got H77? Can anybody here tell me the difference? Thanks.
Sorry, I can't; The wife recycled the carton labeled the serial # of my unit during Grand Cleaninghouse before Chinese New Year. The post # 750 on the following AVSforum thread may help you to verify the actual model of your unit:
Thanks a lot, Powertrip can read the monitor information including the serial No., My serial no. is O81L550A1052. If it read from the registry, it shows the model as OTM3748, otherwise it shows OPTOMA H77.
