Set the Record Straight: CRTs vs. LCDs Better or Worse?

"Have you heard the horror stories of people's eyeballs exploding from staring at their CRT monitors for too long? Though they are scary, luckily they are not true. This article should clear up the pros and cons of the two main display types-- CRT and LCD."

LCD displays are more visible even in slightly lower ambient lighting conditions.

When each pixel on a CRT refreshes it goes light-darker-darker-black, during the "light" phase the pixel on a CRT is actually harmfully bright! Ever wake up and run to your PC only to blinded by your monitor for a good five minutes? You can reduce the effect of this phenomenon by using a CRT with higher persistence phosphor. In turn, producing a gamer’s nightmare, known as “ghosting”. The best solution being, raise your refresh rate as high as your CRT supports.

In comparison to this, LCDs don't flicker anywhere near as much, which makes them much easier on the eyes.

For now the price of LCDs is the only major drawback. If you can find a good deal on a LCD that fits your bill, do your eyes a favor and treat them to it. I myself am looking around for a good deal on a LCD, I have been getting frequent headaches around my forehead/temple after long sessions on my CRT.

Hardcore gamers and creative pros may have some problems with LCDs though. Ghosting and accuracy is still a problem compared with CRTs. Gamers may find ghosting distracting. Creative professionals may find the comparatively lower contrast, color accuracy, and picture accuracy to be problems that outweigh the benefits of LCDs.

But for everyone else that isn’t concerned with extreme picture accuracy, LCDs offer phenomenal advantages over CRTs, with the picture often being better than a standard, cheap, consumer CRT.
