Without a doubt, you can see just how complicated monitors and TVs are. Once you get a taste for all that is going on inside, you really learn to appreciate just how reliable your monitor is. On top of that, you just might begin to realize how unsurprising it is when a cheap monitor fails on you.
A heavy amount of engineering goes into the construction of a CRT display, and what we have here barely even scratches the surface of that engineering. For the end user, it doesn't really matter, since you'll depend on your eyes to determine whether a given monitor's image quality is "good" or "bad." That determination may vary widely from person to person, and can probably be attributed to not only individual taste, but also due to simple variances in human vision from person to person. Nevertheless, most people should be able to spot a good monitor over a bad monitor any day.
