Nintendo Switch Not Connected to TV Solved

When I refer to TV, I mean all kinds of monitors in general.

What Happened?

On a trip, I brought my Nintendo Switch with me. When I connected it to the TV in a hotel, it only showed "No Signal".

Voltage Shortage?

I searched online and found people talking about the same problem. Some say it could the electricity provided by the hotel has too low of a volage tp power the Switch dock.

I tried different  sockets, but with no results.

HDMI cables

Some say it could that the HDML cable is broken. Then, I tried to use a different HDMI cable and it worked.
