I have a display that does not include HSYNC or VSYNC, only a pixel clock. It is my understanding that I can only use the FMC interface (the old FSMC) and not the LCD TFT embedded controller (I have a STM32F429). Is this correct? I just started investigating this, but any pointers in the meantime are greatly appreciated. I'd like to use the LCD TFT embedded controller with the display I already have instead of looking at a new display.
