What To Look For In A Computer Monitor

A computer monitor is important for any computer because it is what brings the world of computers to people visually. There are all sorts of different things to use for a computer monitor. Among the things to look for in a computer monitor, include the resolution of the monitor, its size, the type of display and the refresh quality of the monitor. The size of the pixels in the monitor should also be considered when you are considering what to look for in a computer monitor.

The first thing to look for in a computer monitor is the resolution quality of the monitor. The resolution is based on the number of pixels that are in the monitor screen. When there are more pixels in the monitor the resolution will be better. For instance, a monitor with a resolution of 1600x1280 is better than a 1280x1024 monitor. The horizontal number of pixels is listed first followed by the vertical number.

The next thing to look for in a computer monitor is the size of the monitor. The size of the monitor will refer to how big the screen is from a diagonal measurement. Sixteen-inch monitors are popular but there are other sizes available at typical stores that sell computer monitors. When looking for the monitor that has the right screen size the ability of the user to read what is on the monitor should be greatly considered.

The display type that is used in a monitor is similar to what is used with a television set. Cathode ray tubes are used in larger monitors that have picture tubes working to display images. Liquid crystal display monitors are becoming more popular. This uses a liquid film to display images and is incredibly popular because of the thinner size of the monitor.

It should be noted that the display type is going to make an impact on the colors in the monitor. A cathode ray tube monitor will be easily visible from multiple angles and will do a better job with displaying images. However, a liquid crystal display monitor will be able to bring out higher quality resolution for images. Technology for this is improving though. In fact, it is easier to place on a typical desk because of the smaller width of the monitor.

The refresh quality of the monitor is another thing to think about when looking for a computer monitor. This refers to the highest number of vertical scans that a monitor can produce. A typical monitor will have a range between seventy and two hundred vertical scans per second. When the monitor has a higher number of vertical scans per second that means that monitor will be able to refresh what is on it at a faster rate. There will be less flickering when there are more vertical scans in a second.

While the number of pixels in the monitor is one of the things to think about when you consider what to look for in a computer monitor, the size of those individual pixels should be considered also. Each pixel will have a size in a specific amount of millimeters. The size will determine the dot pitch in the monitor. A typical dot pitch for a quality monitor will be .25. This means that the pixel will be especially small and less than a millimeter in size. Overall, when the dot pitch is smaller the monitor will be better. This means that greater levels of resolution can be created on smaller monitors.

That is what to look for in a computer monitor. The resolution, size, refresh quality, display and the pixel size should all be considered when looking into buying a computer monitor. Not all computer monitors will be the same, so it is important to look into all of these aspects so that it will be easier to find a monitor that is right for one’s individual needs.

Recycling Old Computers To Save The Environment

Many cities, towns and townships are now thinking about computer recycling as well as TV recycling methods to protect the environment and avoid possible soil contamination. Because computers contain many parts that could release toxins into the soil, city governments are seeking alternative ways to dispose of your old computers as well as all your old electronic equipment. This eventually will become a normal practice as more city governments become aware of the potential danger of dumping computers and all electronic products into a landfill. Many groups are also spreading the word about computer recycling and want to find better ways to dispose of the equipment. 

In many cities, there are local electronic stores or recycling centers that will take your old computers and other electronics, dismantle them, and place the right parts in the right containers for disposal. This method of disposal will soon become a necessity because of the computer industries continued upgrading and making more computers that are newer more affordable for the average person to buy. If the computers make it into landfills as they have in the past, it could eventually cause environmental issues that would then need to be addressed by the federal government. 

The issue of recycling computers and other electronics has become a hot computer topic and will continue to be addressed by conservatives and government officials in order to protect the land. Because the monitors as well as televisions have gases and other toxins that if placed in landfill sites could sooner or later release these gases into the atmosphere as well. This is a concern for all who have the ozone and air quality in mind. The gases inside a monitor need to be released safely as you do with a refrigerator or air-conditioner. Without proper release, the air can become filled with these toxic gases. 

When recycling computers, monitors and any printers, people need to take the equipment to a place that is accredited for safely disposing of the equipment in a safe and proper way rather than dumping the equipment in a pile somewhere and hope for the best. It is vital that everyone disposes of their computer equipment properly and take it to a participating recycler in the area. You may have to pay a small fee to drop off your old electronic equipment, but you will also be spending the money wisely to protect the environment. 

One of the issues surrounding computer disposal is the already thousands if not millions of computers, printers and monitors as well as other electronics that are already in landfills all over the world. Many people express concern about ways to clean up landfill sites that already have the electronics dumped there, but the cost would be in the millions to do such a huge project of this sort. Besides the fact that electronics that have been in landfills for some time now have probably already done what harm they could do already. 

Printers just need the ink cartridges and toner cartridges removed before dismantling them. Many stores such as Office Max and other retail electronic stores have barrels for disposing of your old cartridges. Many ink and toner manufactures that sell to stores, supply pre-paid envelopes for sending the old cartridges back for recycling. These practices have been around for quite a while now. This has cut down on ink cartridges and toner cartridges from being pull in landfills. If everyone would learn to recycle computer and electronic equipment, then it will save millions of dollars for future clean up of these landfill sites. 

Recycling old computers to save the environment is necessary and everyone has a responsibility to abide by this practice to protect and preserve land and air quality. With the newer computer systems becoming available for an affordable price and the way technology changes daily, people are going to need new computers and other electronic equipment to keep up with the changing world. Recycling is needed to accommodate all the old equipment that will double if not triple over the next few years.
