Comparision of LCD with CRT Monitor

While CRTs are capable of displaying multiple video resolution without introducing artifacts, LCDs produce crisp images only in their “native resultion” and, sometimes, fractions of that native resolution. Attempting to run LCD panels at non-native resolutions usually results in the panel scaling the image, which introduces blurriness or “blockiness” and is susceptible in general to multiple kinds of HDTV Blur. Although LCDs typically have more vibrant imagenes and better “real-world” contrast ratios than CRTs, they do have a lower contrast ration than CRTs in terms of how deep their blacks are. A contrast ratio is the difference between a completely on (white) and off (black) pixel, and LCDs can have “backlight bleed” where light leaks out and turns black into gray. Nowadays the very best LCDs actually surpass the best plasmas in terms of delivering a deep black, but most LCDs still lag behind. Many LCDs cannot truly display as many colors as their CRT and plasma counterparts, typically ones that have lower-end panel types such as Twisted Nematic panels.

Some LCDs have significant input lags. If the lag delay is large enough, such displays can be unsuitable for fast and time-precise mouse operations (CAD, FPS gaming) as compared to CRT displays or smaller LCD panels with negligible amounts of input lag. Short lag times are sometimes emphasized in marketing.

LCD panels tend to have a limited viewing angle relative to CRT and plasma displays. This can reduce the number of people able to conveniently view the same image – laptop screens are one example.

Some LCD monitors can cause migraines and eyestrain problems due to flicker from fluorescent back lights fed at 50 ot 60 hz
