For an industrial-grade CAT that assures high contrast and high
resolution, the PVM-91 is an ideal choice. The PVM-91 is built
around an industrial-grade CAT that assures high contrast and a
resolution of better than 800 lines at screen center. The monitor is
ideal for color camera calibration, CCTV, studio control rooms or
even as a computer display. You can also team the PVM-91 up
with a vectorscope or waveform monitor.
