Cool TV how to boot directly into HDMI mode?

Recently, users have reported that, “There are elderly people in the home. Every time you turn on the TV, you cannot directly enter the HDMI interface. That is, you need to manually adjust the past. The old man will not change the interface.” I read it at that time, combined my TV, and I also thought about it. Ah, it's impossible to solve such a big TV brand. It's too bad. I haven’t noticed this problem!

Today, I was thinking, wouldn’t it be so bad to open a TV? Open your TV and take a look. It’s not. I’ll talk about how to make cool TV (A55M, that is, 1905 Mango Time Cool TV). Enter HDMI interface mode directly after startup:

After the A55M starts up, the default interface is as follows

Press the right arrow key to enter the following interface

Select settings to enter the next step as follows

After selecting "General Settings", enter the following interface

In the "default source" select "HDMI", note: because my TV has only one HDMI interface, so there is no HDMI1, HDMI2, my TV only memory mode and HDMI, memory mode should be the last boot or shutdown Enter the mode.

Then select "Startup Home" and select Close.

After the setting is completed, the computer will enter the following mode only after the shutdown is initiated.

No boot box is like this
