CRT VS LCD (CAM)

There are important differences to consider between cathode ray tube (CRT) and liquid crystal display (LCD) monitors. Some advantages of CRT monitors include:
  • CRT monitors are less expensive than LCDs, though LCD prices continue to fall.
  • CRT monitors typically produce more accurate colors, though LCDs are improving.
  • CRT monitors don't usually exhibit the blurring and ghosting that LCDs do, because they can redraw the screen faster.
  • CRT monitors support multiple resolutions without a decrease in picture quality.
  • CRT monitors are sturdier and more difficult to damage.

MAJOR ADVANTAGES OF CRT (Pros of CRT, Cons of LCD)
 POINTS
CRT
LCD
Dead / Stuck Pixel
There is no such problem in CRTs as images are painted on the screen.
LCD panels are prone to dead or stuck pixels (or dots) on the screen due to their manufacturing process.
However, stiff competition has made many manufacturers adopt zero dead pixel / stuck pixel warranties for their products.
Response Time
CRTs already have a very fast response time hence this attribute does not apply to it.
This attribute is specially for LCDs as the lower the response rate is, the better the chance of avoiding "ghosting" effect.
Price
Affordable and cheaper than LCDs due to their declining popularity.
17 inch CRT costs around $160
19 inch CRT costs around $225
Considerably more expensive, but prices are dropping fast.
17 inch LCD costs around $275
19 inch LCD costs around $330
Native Resolution
Can be used at any resolution up to the maximum supported. No image quality is lost at any resolution.
Must be used at its native resolution (maximum resolution) for best quality. Using the display at a lower resolution will result interpolation (scaling of the image), causing image quality loss.
This is one of the major reasons for CRTs being in use by gamers as the high native resolution that LCD demands may not deliver smooth frame rates.
Max Colors
32 bit
8-Bit max, 16.7 million colors.
Viewing Angle
Wide viewing angle
Narrow viewing angle, depending on technology employed.
Video
Ideal for any video including HD
Not ideal for Standard Definition videos, but great for High Definition videos
Blackness
True Black
Between Dark Gray to Gray
