BBC News reports here: Chinese computer maker Lenovo offers free software so users can remove hidden software that experts warned made them vulnerable to a cyber-attack.
Some users might think that their current system screen isn’t perfect to meet their desired computing requirements and preferences. It takes a little experience and knowledge to decide an ideal monitor for your productivity companion. Here are some of the general tips that will help you in selecting the right monitor.
No matter whether you’re a homemaker, college student, working professional or a developer, you might be spending endless hours staring your PC screens. Don’t you want your computer components to be stylish enough to catch your friends or colleagues attention? Don’t you think that an appropriate computer screen and optimal PC parts can help you avoid various health issues? If yes, then why can’t you replace your boring box placed right on your workstation? It is true that selecting an ideal monitor might improve your computer viewing experience and also put less strain on your eyes, resulting in optimal productivity without hampering your health. Don’t just get impressed by the specs and monitor jargon that most of the IT manufacturers use in their advertisements instead, you should do the proper research on their features. Simply compare their properties with the below-mentioned details while going for a monitor or computer upgrade.
1. Types of Connections
The first question that you’ll need to focus on is the type of connection your system supports, including the monitor and video output. Sometimes, a video card or motherboard specifications might deny your monitor selection, simply by stating or showing an error related to unsupported computer parts. The two most common connection types for monitors are:
• DVI connectors: These are used as a digital output for PC monitors, and it supports all the modern video cards including DVI video cards and HDMI cards.
• VGA connectors: VGA connectors are generally paired up with an older PC that might not even install a video card or support DVI standards.
2. Screen Size
There is no standard phenomenon behind selecting an ideal screen size as it entirely depends on the user’s preference and personal choice. Cost of the PC monitor also plays a vital role in deciding the screen size.
Following are some of the guidelines you should check before buying a monitor:
• Larger monitors are better for graphics related purposes like watching or editing video, playing graphics intensive video games or giving final touch to your digital photographs
• If you’re looking for a completely productive setup, then use normal-sized multiple displays to finish up numerous tasks within stipulated time-period
• If you don’t use the PC regularly, then you may not need a large display
3. Native Resolution
Modern LCD monitors support pixels technology to provide amazing video and picture quality to its users. Analog CRT monitors can easily use lots of different resolutions without losing the exact quality of an image or video. LCDs employ pixels at fixed points, and this arrangement of pixels combines to make the native resolution of the display.
Consider the following factors to select an ideal computer upgrade:
• Always select a monitor with a high native or recommended resolution
• Ensure that your selected computer components deliver the best possible video quality
• Farsighted users may prefer PC monitors with smaller native resolutions to read small text easily.
4. Brightness and Contrast Ratio
Monitor brightness and contrast ratio can impact the actual functioning of major PC parts and is usually not something that interests a user. Computer screens offering a vast difference between brightest white and the darkest dark settings can be highly dangerous for naked eyes. So keep the following parameters in mind while selecting optimal brightness and contrast ratio of your hardware upgrade for PC monitors:
• Grab a monitor that rates greater than 200 cd/m2 on brightness
• Brighter monitors allow better display of color and better contrast ratios that are ideal for graphics professionals, video editors, and other professionals
• Always avail a device having contrast ratios higher than 350:1 and you can easily find PC monitors at reasonable prices with 1000:1 contrast ratio
• Try to search for monitors supporting Dynamic Contrast Ratios or Advanced Contrast Ratios to enjoy optimal video experience
5. Colors Display
Usually, all computer monitors and displays are capable of producing a full array of 16.7 million colors (24 bit), which is possible by using the entire shades of an RGB colorspace. Some older VGA monitors may not display all of them and only work in color modes having density lower than 24 bit. Old VGA monitors aren’t in style now so replace them with the new DVI monitors that possess all the capabilities to support 24 bit color schemes.
Apart from focusing on all the parameters mentioned above, you can also emphasize on knowing the viewing angles that your monitor supports. Tech geeks claim that enquiring about various computer hardware and PC parts can help you choose the best available option at reasonable prices. An ideal LCD viewing angle falls somewhere close to 180 degrees and can go as high as 170 degrees. Additionally, you should also look for PC response time, and it should have 8ms or faster response time to become a part of the gaming computer components. Practicing these tips while selecting an ideal PC monitor for your system can help you avoid those nasty issues that arise while making hardware upgrade!

The web is full of traps for beginners. While they try to download free software, by clicking on “Download” buttons, in reality they click on fake links that download bundle of toolbars and other junk software. This article will help you in learning how you can avoid downloading of junks into your system.
Usually, geeks know how to dodge the junk files while executing free software download. But novice users mostly don’t know this. In fact, many even don’t know that when they download free game or any other free software, they are also downloading many other junks, which can also be malicious. In the temptation of free games and software, people fall for these tricks.
Read below to enhance your knowledge in this regard so that you can avoid the installation of unwanted files in your system:
Fake Download Links
When you download free software, the first trap that you encounter is the fake download link. You must have seen brightly colored, large buttons flashing the words “Free Download” or “Download Now.”
These buttons are just advertisement banners and are mimicking of real download links. It is created intentionally to trick you into clicking those links and installing different unwanted software.
Next time, when you go for free software download beware of such fake download links. Now the question is how to identify fake links? Just hover the mouse cursor over the link and check where it leads.
For instance, you want to download Adobe Photoshop. You get to a page that gives you a Download button. Now, bring your mouse cursor over that button and check where it leads. If it is a fake link, then it will not take you to the Photoshop page rather it will lead you to a page like “googleadservices.com” that is clearly an advertising link.
Junk Selected By Default Installers
Free software comes with software installers. Even the legitimate installers carry numerous junk software and browser toolbars. The catch is that the developer distributes the software for free and he is making money by including this junk. If you download installers bundled with junks, then it might change your browser’s homepage or default search. Of course, you never want that to happen.
You can easily avoid the downloading of these browsers toolbars and junk. While you download the installer, you go through an agreement process, where you tick the checkboxes and accept the Terms and Conditions integrated with the software. In this page, by default, the check box admitting the downloading of these junk files remains checked. Invoice users just neglect that unknowingly and accept the condition that along with the primary software even the additional junk software will get downloaded. So, you must uncheck the checkbox that permits the downloading of additional software.
Uninstalling the Junk software
However, if you have forgotten to keep that box unchecked and as a result of that junk software got installed in your system, then you must uninstall them.
To delete the bad software, you need to hunt it down. For that head to the Control Panel and here check the list of installed programs. You will find many toolbars or programs that you never downloaded intentionally. These are all junk downloads. You need to install a junk removal tool and run that on those extra and unwanted free software.
You should also run an antivirus program installed on your PC. As many of these junks that came along during free software download are removable even by your antivirus program.
It is unfortunate, but it’s a fact that in the Windows software ecosystem, bundling of unwanted software with installers has got widely accepted. So, it is not going to get over very soon. That is why, you can’t have the careless attitude while you download free games or software. You have to be a bit alert and check whether you are downloading a fake link, or if you have unchecked the added software box, etc. Being careful is the only solution here.

You just turned on your TV and suddenly the picture disappears just a second after it appeared, but you’re hearing the television program through the speakers. If this occurs, your LCD TV’s backlight has gone out. It is like a blown light bulb when you walk into a room, flip the switch and it suddenly blows.
And now you are wondering what to do next.
One of the most common issues responsible for LCD TV failure is backlight failure, but this is not a reason for you to replace your LCD TV. As a matter of fact, you can replace the backlight and do so affordably.
One way you can achieve LCD TV backlight replacement is to take the task on yourself or engage the services of a professional to do it for you, but there are times in which you can troubleshoot the issue on your own.
When the backlight goes, you can take on the task of replacing the inverter board if you can find the exact part. You can contact the manufacturer for this. If you cannot obtain the part, you may need to replace the entire LCD panel.
But you may notice that there may be a note on the back of your TV that says “no serviceable parts.” This doesn’t mean that it can’t be fixed. This simply means you may have difficulty finding the parts. Nevertheless, the job is usually as simple as removing the dead cathode and replacing it with a new inverter and tube. This is actually not as dangerous as opening up non-LCD TVs and trying to replace the parts.
As for what you invest in the task, it is possible for LCD TV backlight replacement to take about thirty minutes of your time and cost you as little as $20. Online outlets, school surplus, and stores selling new and/or used replacement parts are places you can buy what you need.
Take note that you may need to desolder and solder wires depending on the model of your television.
Being that the job of LCD TV backlight replacement can take less than 30 minutes of your life and cost you very little, it can be difficult considering a professional. However, not everyone is comfortable with taking their expensive LCD TV apart and desoldering, soldering, and putting in a replacement part.
A professional is able to find the part, take care of the installation, test it to make sure it is working, make it right if the TV is not working, and can offer some degree of a guarantee if the backlight fails within a certain amount of time. However, such a service does cost money and you must compare the cost of such a service to you buying a new television. If you find that buying a new television would be an option, then it would be worth you attempting the LCD TV backlight replacement on your own. If replacing the backlight on your own does not work, the amount of money you are out of is small and you can go forward with buying a new LCD TV.
Nevertheless, it may be worth attempting the replacement task on your own.
