CRT (cathode-ray tube) monitors are still being manufactured, but in far fewer numbers than the preferred LCD monitor - and for good reason: a CRT computer monitor is heavy, bulky, and has a lower resolution compared to more modern versions such as the LCD monitor. They also display in a 4:3 aspect ratio, which is not ideal for watching movies shot in widescreen (16:9) format, unlike the preferred LCD monitor.
A computer monitor's aspect ratio is the ratio of an image's width to its height, so an LCD monitor with a 4:3 aspect ratio is almost square, while one with a ratio of 16:9 is wider than its height.

The LCD monitor has become the preferred standard monitor in households and offices.
A 15-inch LCD monitor, once the standard, is now almost impossible to buy brand new. A 17-inch LCD monitor is usually the smallest available nowadays, and is usually inexpensive to purchase. If you do not have a lot of money to spend and find yourself in need of a computer monitor, a decent, basic 17-inch model can be purchased at an affordable price. However, compare prices of LCD monitor models for the next size up, as you will probably find that for a small additional expense you can have a larger computer monitor size.
A 19 to 20-inch LCD monitor is about the median size right now and can be obtained at a very reasonable price. You can comfortably view photos and videos, enlarge text for easy reading, and wo
