Computer Monitors Reviews

It may be amazing to current computer users who are used to small compact LCD monitors. Not only were initial computer monitors huge and cumbersome but that the early monitors used by computer enthusiasts were Cathode Ray Monitors that weren’t color,

Initial vintage monitors were monochrome one color only not the brilliant color displays that we take for granted today.

Some of these monochrome monitors were green or orange iridescent. Others were similar to a black and white television that is grey scale.

It is taken for granted now by young computer surfers and gamers that television was always color”, not so.

Initially TV broadcasts were in black and white .

Color TV had been developed but the technology but the widespread use did not arise till the early 1970’s and even later in any areas.

The broadcasts were seen as black and white on those sets and color on color sets.
Color televisions could receive programs that were in the black and white mode as well. Sort of the backwards compatibility of the day.

What then would be the difference between the picture qualities of a television set a monitor has vastly greater resolution than standard TV sets.

The TV sets of that time (as opposed to current high end LCD and plasma high definition TVs) were basically 1950’s technology even the newer color TV sets. .

A monitor’s screen display should be stable and of good quality, since the computer user may sit very close to the monitor and spend many hours reading the display.

If the images are fuzzy (low resolution) or waver constantly, you would have a throbbing headache and wavering eyes in no time.

Monitors have knobs to adjust for clarity. On vintage monochrome monitors these mostly include a brightness knob which adjusts the illumination of the entire screen, and a contrast knob which makes the letters lighter or darker in relation to the background screen newer color monitors will have additional adjustments for color.

The question will arise how did the vintage CRT (Cathode Ray Tube) monitors initially handle the color technology which came later and became the accepted standard.

A typical color monitor screen worked in much the same way as a standard CRT television.

The inside of the picture tube is coated with three different phosphors: red, green and blue.

Phosphors are special chemical compounds that glow with characteristic colors when bombarded a stream of electrons.

The phosphor gets excited” and thanks to the additive properties of the color wheel the different colored lights resulting get mixed and that all types of combinations of the three primary colors result.

The end result is that virtually any color of the rainbow might be produced.

And as for the color white the eyes play a useful trick. When all three colors are mixed together in equal quantities, the eye sees this as white light”.

Finally the sharpness of the CRT color monitor or a TV set’s image is determined by three factors: the monitor’s bandwidth, its dot pitch, and the accuracy of its convergence.

Although the bandwidth and dot pitch are important to determine a good monitor, convergence is the real measurement.

Indeed we’ve come a long way from the initial easy vintage monochrome monitors. What we now take for granted with LCD monitors and indeed our high definition TV sets all originated with easy CRT monochrome monitor technology which was merged with the technology and tricks gleaned from the color TV industry.

We should all be grateful. We owe much to “Uncle Miltie”.

Computer Repairs

For those who cannot manage it, it is best to rely on the manufacturing company for computer repairs, especially till such time that the machine is covered by extended warranties. After that, they can use the help of a company that provides services at fixed or variable costs. Since computer service is a survival necessity in the present day world, computer users should have ready access to computer repair options. At the same time, they should also know any of the tips and tricks to get things done cheaply, and without hassles.

The first rule here’s for the users to learn any of the basics of computer repairs so that they can manage minor repairs themselves. The operating system will have its own troubleshooting options, and by going through it step by step users will be able to rectify any of the problems themselves. Later versions of windows come with repair disks and when the user boots the computer with it, again, it will have provisions for guiding the users through means to get the problems fixed.

Anyway, repair disks won’t solve the entire gamut of problems that make computer service necessary. Further, there are plenty of people whose technical know-how does not allow them to manage computer repairs even with the repair disk and other troubleshooting options that operating systems provide. They might have to get outside help to have the problem rectified.

While taking outside help for computer repairs, it is better not to rely on help from independent sources till such time that the machine is covered by the manufacturer’s warranty. The warranty terms of different manufacturers will vary, but many machines are covered by extended warranties at additional costs even after the mandatory period of one-year warranty. During this period, computer service by the sellers will always work out cheaper than getting it from other sources. Further, spare parts availability for the brand will also be more with the manufacturing company than others.

In any cases, where on site computer repairs is required, and there could be delay in getting the services of the manufacturers, the user may have to rely on help from other sources. However, the cost equation here will have to be calculated by comparing the extra charges that could ensue from taking that help, and the loss resulting from the delay in getting the manufacturer’s computer service.

In a post warranty period scenario, there are mainly two ways in which computer service will be available. One is by entering into an annual maintenance contract with the service provider. Here, in return for the payment of a fixed amount mostly all year, the service providers will take care of all the computer repairs needs of the user.

Also with the other option, the computer owner will have to purchase each repair separately and also purchase spare parts when necessary. It is a bit difficult to predict which of the two methods will work out to be cheaper in the long run. In the case of businesses where malfunctioning of a computer could result in substantial business loss, contracts that’ll cover all computer repairs could be the better option. For smaller units and home computers, computer service with variable charges may be the right option.

Computer Power Cord

A computer power supply is a component that supplies power to the computer and provide support to the computer to perform its functions. It is one of the most vital components to operate a computer. Without it a computer is just a junk box filled up with metal and plastic.

The SMPS is the device that converts the alternate current that is provided to your home to the direct current that is needed by the personal computer. In a computer the SMPS is the metal box that we find in the corner of the case of the central processing unit. It can be seen at the back of many systems since it contains a cooling fan and the power cord receptacles. The switches that the computer power supply contains actually control the flow of the volt power of the power supply to the computer.

Today you can turn off your personal computer with a small button or the turn off option from the menu bar. These capabilities have been added to all the latest computers that are manufactured today. The operating system can send a signal to the power supply so that it can be turned off. It also has a circuit that supplies 5 volts even when the PC is off so that the button will keep working.

It is not a big thing that cannot be replaced if in case it blows or turns down. They contribute a lot in turning the computer on and off. Trying to mess with it may cause you severe injury since it is an electrical component. There are many important measures that you should keep in mind to safeguard yourself from the blown unit. Always unplug the computer when not in use. By keeping it plugged in even if the computer is off, still there is electricity active between the PC and the wall. So, it is advised to keep it unplugged for your safety.

And also when the weather is bad and there is thunder or the clouds are roaring, unplug it right away. This will keep you safe by saving your computer power supply and make an installation later if it breaks down. The computer power supply can be replaced easily, but to find it is not so easy at your local stores. The computers are upgraded after every two years, so in case you have to replace the computer power supply, you will find it difficult to an SMPS matching your old computer with the arrival of the latest technologies. The best way to replace it will be to contact the computer manufacturer. They will surely be able to find a solution to our problem. There are many online manufacturers where you will find the one that you are required. The local stores can also easily assist you with the basic requirements.

Receiving enough server impact can also damage the computer power supply. That is why; investing in a power surge for the computer components can have you solve the problems quite easily. The other way through which you can safe guard your PC is that you should not leave the computer running for the whole day and avoid frequent switching the computer on and off. All the above initiatives will surely help you to run the computer power supply for much longer period.
