You're missing my point, pnayak15. Look at the pinout for a VGA connector:

That pinout certainly does not match your FPGA output. This is an analog interface, not DVI/HDMI as I suspected. So your FPGA output is driving the input to a video encoder chip on your board. Please find out what that chip is, get a data sheet, and make sure you're using the chip correctly (giving it all of the proper input signals that it needs).
