Other Considerations in Choosing Monitors
Cost and Picture Area
There is a direct link between the size of the picture tube and the cost of the monitor. The CRT is the most expensive part of the monitor. GUI operating systems have increased the demand for big screens, to allow for more working area so that the user can have more applications open at once, or more working room for graphics.
Bandwidth
When referring to computer monitors, the term bandwidth is used to denote the greatest number of times an electron gun can be turned on and off in one second. Bandwidth is a key design factor, because it determines the maximum vertical refresh rate of a monitor. It is measured in MHz. Higher numbers are better. The lower the resolution, the faster the bandwidth. When comparing products, remember to measure bandwidth at the same resolution for each product.
Interlacing
Interlacing refreshes the monitor by painting alternate rows on the screen and then coming back and sweeping the sets of rows that were skipped the first time around. This increases the effective refresh rate, but can lead to eyestrain. Interlacing is found on less expensive monitors, and should be avoided unless achieving the very lowest initial cost is the client's key concern.
