This is untrue. What is true is that CRTs lose brightness over time and often aren't made to produce as much light as LCDs are. Just look at the difference between blacks on an LCD and blacks on a CRT.

There is no question that tube will provide you with more accurate color, essentially unlimited resolution, etc.

However, there is no question they are bulkier, use more power, and don't look better to 95% of people who have no sense of the difference even if the two were side by side. Of the 5% who can tell the difference, 4% prefer the convenience of an LCD and other benefits, and 1% need to use CRTs because of their profession and hobbies requiring the absolutely most accurate colors possible.

Even just 3-4 years ago, those numbers would more be like 4.5% of the 5% needing the CRT, but LCDs have gotten better and now gamers have no ghosting issues with LCDs, etc.

So the bottomline is, LCDs are better for consumers, businesses, most end users, etc. For some professionals, nothing yet beats a CRT.

However, LED backlit screens could change all of that...
