Abstract
In a CRT display exhibiting a Rho-Theta format where certain of the lines would normally extend beyond the edges of the CRT screen, feedback signals from at least a deflection coil are used to terminate display lines at the edge of the screen and to initiate immediate retrace. Compensation is applied to at least a deflection voltage to compensate for display line bunching caused by unequal scan line times.
