The gt9xx-1080x600 module is not a random part; it appears in specific, high-volume hardware ecosystems.
It is rare to drive 1080x600 directly from an MCU because of RAM limitations. 1080x600 at 16-bit color depth = 1,296,000 bytes (1.2 MB) per frame. A standard STM32F4 has 192KB RAM. Therefore, you almost always need an external SPI RAM or an SPI-to-MIPI bridge chip (like the SSD2828) for MCU usage. gt9xx-1080x600
