I am using NX4827P043-011C nextion display but I face an issue is that when power is on the display will flicker a moment and then back to normal as shown in the video below

this is my code to control the brightness of the display when powered on:
dim=0
delay=1000
for(dim=0;dim<100;dim++)
{
delay=100
}
delay=2000
dp=1

 

What happens when you remove the code to control the brightness altogether?

@ericgibbs used the VLC freeze frame to isolate the “flash” and see what was really happening.
