CRT computer monitors give you more pixels for the money compared to an LCD. More pixels allow you to see more detail on the screen, and you’ll be able to view more of a document or web page without scrolling. A 19-inch CRT monitor with 1600 x 1200 resolution can easily display two full-sized documents side-by-side, but to get that same resolution in an LCD, you’ll have to spend upwards of $350 on a 20-inch or larger model.

Another area of concern, especially for graphic artists, is color fidelity. Again, improvements have been made to contrast ratio and the number of displayable colors in LCD displays, but many photographers and graphics pros still feel that they get truer color, for the most part, on a CRT. Still, this is a segment that has begun to move to LCD in growing numbers.

Finally, there’s the viewing angle issue. If you’ve ever looked over someone’s shoulder onto a laptop or LCD, you’ll understand this problem immediately. The best view on an LCD monitor is always straight on. The primary user will get the best screen image. People who might be sitting to the left or right won’t get the best color or clarity, and if they are sitting too far to one side, the image disappears from view entirely. Again, in this area, LCDs are improving, but CRT monitors still have the upper hand. CRT images look virtually identical from wherever you are viewing the scree

Which Monitor is the Best to Buy?

Introduction

This question is actually much less valid than it was several years ago. Many companies have cut the production of CRT monitors except for the extremely high end and the very low end. In fact, most desktop computer systems sold now by default come with LCD monitors. Still for those that what to know the difference and which they would be better off purchasing, I have updated this article to be more relevant to the current technologies and products offered today.

CRTs

The primary advantage that CRT monitors held over LCDs was their color rendering. The contrast ratios and depths of colors displayed were much greater with CRT monitors than LCDs. While this still holds true in most cases, many strides have been made in LCDs such that this difference is not as great as it once was.

Many graphic designers still use the very expensive large CRT monitors in their work because of the color advantages. Of course, this color ability does degrade over time as the phosphors in the tube break down.

The other advantage that CRT monitors held over LCD screens is the ability to easily scale to various resolutions. This is referred to as multisync by the industry. By adjusting the electron beam in the tube, the screen can easily be adjusted downward to lower resolutions while keeping the picture clarity intact.

While these two items may play an important role for CRT monitors, there are disadvantages as well. The biggest of these are the size and weight of the tubes. An equivalent sized LCD monitor is upwards of 80% smaller in size and weight compared to a CRT tube. The larger the screen, the bigger the size difference. The other major drawback deals with the power consumption. The energy needed for the electron beam means that the monitors consumer and generate a lot more heat than the LCD monitors.

Pros:

* Multisync Capable
* High Refresh Rates
* Color Clarity and Depth

Cons:

* Very Heavy and Large
* Use Large Amounts of Energy
* Generate Excess Heat

LCDs

The biggest advantage to LCD monitors is their size and weight. As was mentioned earlier, the size and weight of an LCD monitor can be upwards of 80% lighter than an equivalent dimension CRT screen. This makes it possible to users to have larger screens for their computers than was possible before.

LCD screens also tend to produce less eye fatigue to the user. The constant light barrage and scan lines of a CRT tube tend to cause strain on heavy computer users. The lower intensity of the LCD monitors coupled with their constant screen display of pixels being on or off produces less fatigue for the user.

The most notable disadvantage to LCD screens is their fixed or native resolution. An LCD screen can only display the number of pixels in its matrix and no more or less. It can display a lower resolution in one of two ways. Using only a fraction of the total pixels on the display or through extrapolation. Extrapolation is a method whereby the monitor blends multiple pixels together to simulate a single smaller pixel. This can often lead to a blurry or fuzzy image particularly with text when running the screen below is native resolution.

Video was problematic with early LCD monitors because of lower response times. This has been overcome by many improvements, but there are some that still have low response times. Purchasers should be aware of this when purchasing a monitor. However, the improvements are often work arounds that can actually lead to another problem of reduced color clarity. Unfortunately, the industry is very poor about properly listing the specifications for monitors to help buyers understand and compare monitors.

Pros:

* Smaller and Lighter
* Energy Efficient
* Causes Less Eye Fatigue

Cons:

* Blurry Images Outside Native Resolution
* Motion Blur on Fast Moving Images
* Come Models Have Reduced Color Clarity

Conclusions

At this point and time, most consumers will likely be purchasing LCD monitors over CRTs. There is almost no difference in the cost to consumers thanks to production improvements in LCDs and the reduction in the production of CRTs. Typically CRTs will only be seen sold with the least expensive of desktop computer systems or by those with special imaging needs such as graphics and medical professionals.
