Why do old crt monitors have better picture quality than lcds?

Q. I have a 22" 1920x1080 lcd monitor on my computer. Well the other day I went over my friends house and he had a old CTX 17" crt monitor, and it was the clearest thing I ever seen. Perfect black levels, very crisp text, and the colors were much richer. Why does his crt have a better picture than my 22" 1080p full hd monitor?

A. It really depends on your LCD monitor, there are cheaper models with less mature technology, whereas CRTs have been around a long time and hence it's cheap to produce good models, and they don't (afaik) make them anymore.

Try look at high-end IPS monitors, which do have much better colour reproduction, viewing angles and then the price :P.

People moved to LCD, not because of image quality, but for energy-efficiency and how light it is.


How has computer LCD monitors changed over time?
Q. i need help! pls tell me how has the computer LCD monitors changed and developed over the past years!!!!! a million thx to u all!

A. Yes.

The biggest change has been the drop in price.

TN technology has been a mainstay of LCD panels, but has become faster to respond and the introduction of prismatic layers has improved the viewing angle.

Alternative liquid crystal orientations have improved viewing angles - In-Plane-Switching (IPS) and a variety of vertical alignments and also has better gray scale tracking for luminance and colour. Usually at some level of price, brightness and response time.

Improvements in the scaling algorithms has made the display of non-native resolutions better (but still not especially good)

Improvements in the DLP processor in the monitor have given better uniformity and better response time (by overdriving the pixel for 1 cycle to get the crystals to move faster)

Improvements in the CCFL backlights have made them brighter.

Improvements in the colour dyes have produced better colour ranges.


The breakout of LCD TVs has also meant that prices have dropped and screen sizes have gotten larger as the manufacturers have set up production lines for bigger and bigger pieces of glass.
