I tested it with 4 different HDMI cables at home, but the symptom did not improve at all. About 30 percent boot at once, and the remaining 70 percent do not boot at once and have to boot twice. This is quite annoying. There are users in Korea who have similar symptoms with various products using n100 cpu. They say that if they turn off the monitor completely, turn on the main unit, and then turn on the monitor again, the booting goes normally. It definitely seems that some products using n100 cpu have compatibility issues with specific monitors.
