-**color_palette** (*Optional*): The type of color pallet that will be used in the ESP's internal 8-bits-per-pixel buffer. This can be used to improve color depth quality of the image. For example if you know that the display will only be showing grayscale images, the clarity of the display can be improved by targeting the available colors to monochrome only. Options are:
-**color_palette_images** (*Optional*): A list of image files that will be used to generate the color pallet for the display. This should only be used in conjunction with ``-color_palette: IMAGE_ADAPTIVE`` above. The images will be analysed at compile time and a custom color pallet will be created based on the most commonly occuring colors. A typical setting would be a sample image that represented the fully populated display. This can significantly improve the quality of displayed images. Note that these images are not stored on the ESP device, just the 256byte color pallet created from them.
-**dimensions** (*Optional*): Dimensions of the screen, specified either as *width***x***height* (e.g ``320x240``) or with separate config keys. If not provided the dimensions will be determined by the model selected.
-**height** (**Required**, int): Specifies height of display in pixels.
-**width** (**Required**, int): Specifies width of display.
-**offset_width** (*Optional*, int): Specify an offset for the x-direction of the display, typically used when an LCD is smaller than the maximum supported by the driver chip. Default is 0
-**offset_height** (*Optional*, int): Specify an offset for the y-direction of the display. Default is 0.
-**invert_colors** (*Optional*): With this boolean option you can invert the display colors. **Note** some of the displays have this option set automatically to true and can't be changed.
-**rotation** (*Optional*): Rotate the display presentation in software. Choose one of ``0°``, ``90°``, ``180°``, or ``270°``. This option cannot be used with ``transform``.
-**transform** (*Optional*): Transform the display presentation using hardware. All defaults are ``false``. This option cannot be used with ``rotation``.
-**swap_xy** (*Optional*, boolean): If true, exchange the x and y axes.
-**mirror_x** (*Optional*, boolean): If true, mirror the x axis.
-**mirror_y** (*Optional*, boolean): If true, mirror the y axis.
**Note:** The ``rotation`` variable will do a software based rotation. It is better to use the **transform** to rotate the display in hardware. Use one of the following combinations:
With 90 and 270 rotations you will also need to swap the **dimensions** ''height'' and ''width'' (see example below.
To modify the SPI setting see :ref:`SPI bus <spi>` . The default **data_rate** is set to ``40MHz`` and the **spi_mode** mode is ``MODE0`` but some displays require ``MODE3`` (*).
**Note:** The maximum achievable data rate will depend on the chip type (e.g. ESP32 vs ESP32-S3) the pins used (on ESP32 using the default SPI pins allows higher rates) and the connection type (on-board connections will support higher rates than long cables or DuPont wires.) If in doubt, start with a low speed and test higher rates to find what works. A MISO pin should preferably not be specified, as this will limit the maximum rate in some circumstances, and is not required if the SPI bus is used only for the display.
