Dear @deepakrajpoot,

Thank you for your message. You could try the following to get your display up and running:

  1. We advise you to set-up display configuration in U-boot (Display Output, Resolution and Timings (Linux) | Toradex Developer Center) and saveenv. Please make sure to enter your display resolution and RGB (based on the bit), depending on the monitor. This shoudl solve the issue

  2. If the issue still persists, you can modify the file ( drivers/video/fbdev/mxc/mxc_lcdif.c ) with the necessary vsync and hsync settings (from the monitor’s datasheet) and re-compile the kernel.

Thank you and regards,
Janani.
