Enable this option if you wish to allocate the color buffer used by LVGL from PSRAM.
Unmatched PSRAM band width with LCD requirement can lead to blurred image display.

10 months ago I have the same display, and was facing the same issue. The display requires the PWR_EN (IO10) to be HIGH for the display to be ON. I added the below code and was able to get the example to work.
First defined the pin PWR_EN
#define PWR_EN_PIN 10
before app_main
static void pwr_en(void)
{
// Set the GPIO as an output
gpio_set_direction(PWR_EN_PIN, GPIO_MODE_OUTPUT);
gpio_set_level(PWR_EN_PIN, 1);
}
in the app_main section on the first line added
pwr_en();
On compile and flash the example was displayed. Hope it helps
