beam deflection वाक्य

:: : OK, then that's a very different problem, it is called " beam deflection ", there are multiple online calculators that can do calculations for you, but right now I can't find the one that matches your needs precisely ( most will do calculations for a beam that is attached at one end, or for a solid beam on two supports ).
This does not usually cause a problem as the porches are merely intended to act as blanked-video buffers offering a little overscan space between the active area and the sync pulse ( which triggers, in traditional CRT monitors, the phosphor beam deflection " flyback " to the upper or left hand side of the tube ) and thus can be safely overrun into by a certain amount when everything else is operating correctly.
