ABSTRACT OF THE DISCLOSURE This invention discloses a high frequency two way scan circuit for causing trace and retrace scans on a cathode ray tube having a yoke. A sweep means is connected to the yoke for causing the trace to sweep across the tube and a receiving means is provided to receive a trace sync signal. A first circuit turns off the sweep means during the retrace and a second circuit is provided for turning on the retrace means. The cathode ray tube having this circuit permits an extremely high resolution cathode ray tube display which has unparalled clarity and resolution when compared to the prior art devices.
