Resolution Problem

I had made my custom resolution into 1366x768. But when I go to display setting and apply 1366x768 my monitor become blank.

But when I apply xrandr --output VGA1 --mode "1368x768_60.00" this command my screen resolution become 1366x768. After restart It again become 1024x768.

Now what to do?
