    • Hi,

      this looks like a hardware issue.

      Which driver are you using?
      GUIDRV_Lin?

      Are the clock settings for the LCD correct (like HSYNC, VSYNC, pixel clock, front and back porch etc.)?

      Regards,
      Sven

    • I think its more with stemwin.
      Previously I was able to use graph widget in LPC1788, library released by NXP.(Hauyo board)

      Also with the same configuration (Clock and external sdram) I was able to use touchgfx on ST board.
      Which driver should I use?
