2 Converting Scoring Overhead CRT’s to LCD displays
Replacing scoring CRT monitors with LCD displays provides a significant improvement in
readability and consistency of display. The conversion is simple and immediately improves
the overall look of any scoring system.
LCD monitors are “fixed pixel” displays which can’t suffer from mis-convergence, focus and
color tracking problems so frequently seen in CRT displays. In addition, they don’t rely on
kilovolt power supplies, so they won’t attract dirt to the screen.
There are also things an LCD can’t do. It’s important to be aware of these when
contemplating a conversion.
1) LCD’s can’t increase the resolution of the picture. They can display the existing
resolution in much finer detail and with greater clarity, but a 320x240 picture will
remain a 320x240 picture enlarged to fit the LCD screen. The scoring display won’t
suddenly become High Definition because you installed a new monitor.
2) Bad video with hum, snow, sparkles and jitter will remain bad video with hum, snow,
sparkles and jitter, displayed brighter and clearer than ever. Replacing the display
isn’t going to fix-up the bad video. You have to clean up the interference and noise
and get rid of the hum to realize the full benefits of replacing the monitor.
