Cleaning Your Monitor
You will want to clean your monitors from tiem to time if you do not want it to be blurry and covered with dust. You will notice that your monitor needs cleaning if you start having problems like, for example, the screen starts to be blurry due to being covered with dust. Of course, you should unplug your monitor before you start cleaning it. After all, you do not want to damage it while cleaning. You should use compressed air to clean it from the back to the front. Never open any covers of the monitor. Compressed air in general is great when it comes to cleaning computer components, not only monitors. When it comes to the back side of your monitor, use dampened cloth and paper towels to dry it. Do not use too much water, and do not use any liquids near the ventilation hole of your monitor. Humidity is quite harmful, however, actual liquid could deal some serious damage. Remember that the monitor screen should always be cleaned with soft cloth. That way you will avoid any unnecessary scratching.
I hope the advice given above will be useful to you. After all, you want to keep your monitors in good shape for many years. Even if you will decide to replace your monitor for a newer model, you will be able to fetch a higher price if the monitor was taken care of properly. In the long run this can save you a lot of money.
