Hello @vipuljain91,
You could try modifying those values in display_support.h file:

[guix_washing_machine -> board -> display_support.h]
Please modify the DEMO_PANEL_WIDTH, DEMO_PANEL_HEIGHT, and DEMO_BUFFER_COUNT (lines 25 to 29) to the values your display has. Example:
#define DEMO_PANEL_WIDTH 320
#define DEMO_PANEL_HEIGHT 480
#define DEMO_BUFFER_COUNT 1
Hope this helps.
Best regards, Raul.
