ESP32 NodeMCU + SSD1322 OLED 256x64

i'm trying to figure out how to connect my SSD1322 OLED via SPI to my ESP32 (using the U8G2 library).

Here's my ESP32 Board:

here's my SSD1322 display:

I managed to run it using these settings:

#define SPI_CLOCK 14
#define SPI_DATA 12
#define SPI_CS 15
#define SPI_DC 27

U8G2_SSD1322_NHD_256X64_F_4W_SW_SPI u8g2(U8G2_R0, SPI_CLOCK, SPI_DATA, SPI_CS, SPI_DC);

But it's SW mode and therefore extremely slow (about 2 fps only).

So I need to know how to run it in HW mode but i don't know which U8G2 initialization to use and how to connect it properly.

I think it's this setting:
U8G2_SSD1322_NHD_256X64_F_4W_HW_SPI u8g2(U8G2_R0, SPI_CS, SPI_DC, SPI_RESET);

Can anyone help me out about the pinout plz?
Thanks!

Very wise to start with the SW constructor.
Now change SPI_CLOCK to 19 and SPI_DATA to 23. Verify SW connstructor.
Repeat with the HW constructor i.e. VSPI.
Repeat tests with 14, 13 for HSPI

Edit. Your photos make no sense. An orange wire goes from GPIO4 pin on the ESP32 to DC on the SSD1322.
Arduino numbers for ESP32 tend to match the GPIO number e.g. digital#19 is GPIO19
I am not at a PC. Which board have you selected in the IDE ?
