Monitors features 

Compatibility: First demand for any monitor is compatibility with the other parts of the computer system. Input signal to the monitor must be compatible with output signal from the PC. Check out the documentation for  the video card on your PC to make sure that it will be able to support the resolution and refresh rate of the monitor you select.

Digital/Analog Input: All CRT monitors use a standard analog input from the PC. LCD or flat panel monitors use a Digital Flat Panel (DFP) port. These inputs improve image quality and reduce the price of the monitor. But, these inputs require that the monitor is used with a PC from the same manufacturer that also has a DFP output.

Monitors size: Monitors come in different sizes. Usually you can buy 15,17,19, 21 , 23-inch and more sizes of the monitors. The VIS(Viewable Image Size) is the area that will be your available workspace generally about an inch smaller than the screen size. The large size monitors (17 inches or more) cost more money and use more energy than smaller ones. But you will get additional workspace, more control over image resolution and appearance, and less strain on your eyes. If you look at extensive on-screen documents and spreadsheets, if you design your own web site, or even if you just play many of the newer computer games, a large-screen monitor is the best choice for you.

Resolution: A monitors resolution is measured in number of pixels used to create the image. Most monitors have a resolution of 800 x 600 pixels up to 1280 x 1024 pixels. and more... The first digit is the number of pixels that can be displayed horizontally on the screen, and the second digit how many can be displayed vertically. The higher the resolution, the more pixels that can be displayed. The more pixels, the crisper the image will appear. 

Refresh rate: To avoid a "flickering effect on your screen, you will want to check for a high refresh rate the number of times per second the image is redrawn on the screen. A refresh rate of 75Hz or higher, is essential for standard monitors. LCD monitors have a fixed resolution, so refresh rate is less important.

Dot pitch is the spacing between the colored dots that form the image on the screen. The smaller the dot pitch, the sharper the image. Look for a dot pitch of .28mm or less to ensure a clear, sharp picture.

Aspect ratio: The aspect ratio of the image is the ratio of the number of horizontal  pixels to the number of vertical pixels. The standard aspect ratio for PCs is 4:3, but some resolutions use a ratio of 5:4.

Anti-glare coating makes it easier to look at the screen under a bright light. Lastly, the shadow mask can make a difference in picture quality.

Energy Star Compliant: Energy Star is a voluntary rating system established by the U.S. Department of Energy, the U.S. Environmental Protection Agency and electronics manufacturers. Energy Star labeled products usually surpass Federal energy efficiency standards by 20% or more.

MPR Compliant, Blue Angel Compliant, etc. The term MPR compliant for CRT monitors refers to a Swedish standard for electromagnetic radiation.  This monitor radiation can be from low-frequency magnetic fields, electric fields, x-ray radiation, and static electric fields.  This standard is quite comprehensive and various measurements are made at different points on the monitor for all of the mentioned types of radiation.  These are given certain acceptable limits and it is a good assurance that the monitor is as safe as possible. Most monitors now comply with this standard. "Blue Angel Compliant" means to meet the German's requirements for lower power consumption and environmental specifications. It guarantees employers an easy compliance to the latest European social directives on Visual Display Units (VDU).

Screen Controls: Many monitors have on-screen controls (ONC), enabling you to see the adjustments you're making to monitor as you make them, on screen.
