ST7789 Display Don't Work

Using Arduino Displays
1

Hello everyone. I have a 1.3" ST7789 OLED Display. I try connect to Arduino Nano like this video:

I use Arduino ST7789 Fast library and Adafruit Benchmark like this👆🏻

However I upload the code and when I start, the screen is really black and sometimes I see colours but it's wrong. But if I press the reset button, I see only a frame.

Why? And What should I do?

In the video, an Uno is used, not a Nano.

You should read the forum guide in the sticky post at the top of most forum sections. This will tell you what to post and how to post it, so that the forum will be able to help you.
