How to connect Nextion Display 7" to PC through USB-TTL adapter?

Hi everyone, I bought a Nextion Display 7" (enhanced version) and at the beginning I connected it with Arduino Mega. It works well, but I want to change the baudrate value so I've red that I have to connect the display to PC through an USB-TTL adapter. When I try to connect it, and for example I try to upload my project from the editor, an error message is showed; the text is: "Connection failed. Forced interrupt!". So I cannot send command to display. How can I solve this problem?
