Flat Screen Monitors - A Buyer's Guide

By
The tipping point has arrived. Flat screen monitors have become widely accepted as the new standard for media displays in computing, and with good reason. Flat screen monitors are slim, and fit on desks that couldn't hold a conventional CRT monitor, with a tube. They also require less energy to power and thus produce less excess heat, creating a safer and more economical environment in which to complete your work.
Additionally, within the past year or so prices on flat screen monitors have dropped markedly, making them more accessible for buyers everywhere. This combination of factors has come together to create a perfect storm in the market, flooding sales floors all over with a veritable smorgasbord of monitor options. Picking the right one can be a long and arduous process, but can be made much easier if you keep a few simple rules in mind.
RULE 1
DECIDE WHAT SIZE YOU WANT BEFORE YOU GO SHOPPING Picking the correct size monitor for your media needs is an essential part of this process. Will you be primarily watching movies on your computer? If so, consider a wide-screen monitor that will fit the ratio of most letter-box movies, this will not only increase your viewable area on the monitor, but will also result in a more fulfilled viewing experience. Plan on doing word processing, emailing and other standard desktop activities? Then you probably don't need an excessively large or wide-screen monitor.
For the most part, flat screen monitors start at about fifteen inches and work their way up to in excess of thirty-two. Picking a size that fits your needs, and your budget is a critical part of this process.
RULE 2
LCD, PLASMA OR LED - WHAT'S THE DIFFERENCE?
LCDs Liquid Crystal Display, or LCD flat screen monitors use a backlight to send light through the liquid crystal molecules and the substrate. LCD flat screen monitors work through applying voltage to the pixels using a complex series of interconnected diodes, the pixels can be lightened or darkened to prevent the backlight from shining through. The problem with LCDs is their inability to show true blacks. So, if you're a film or photo editing guru, an LCD may not give you the color matching quality you need.
PLASMA Plasma screens are basically a network of multicolored phosphors (red, green and blue phosphors which combine to create a single pixel) mounted between two ultra-thin layers of glass or clear substrate. Plasma televisions use a submicron pulse for each triad of phosphors to excite the argon, neon and xenon used to produce the color information and light. As energy excites the phosphor molecules, the oxygen atoms dissipate and create the fourth state of matter, plasma, and emitting UV light in the process. The gases used within a plasma television actually have a half-life and will fade over time. Meaning, a plasma television is not a good long-term media option.
The problem is that they're relative power hogs, using more than 5x the electricity that a standard LCD uses. So if you're trying to think green, plasma is not the way to go.
RULE 3
YOUR BUDGET
LCD flat screen monitors are much cheaper than their plasma or LED counterparts, so keep that in mind when setting a budget. Also, think about how long you plan to use and have the monitor, if it is for the spare bedroom, you may not need it to have a high contrast ration or display resolution. If you plan on using it daily, and want it to last a while, then it might be time to shell out a bit extra and pay for the quality and longevity you deserve.
CONCLUSION Follow the rules and you'll be sure to end up with a flat screen monitor that matches your exact needs without breaking the bank.

How to Choose The Best Data Recovery Service Los Angeles Has to Offer

Data Recovery Service Los Angeles
"Anything that can go wrong will go wrong." Even if you've archived your important files online or locked your storage media in fireproof or earthquake-proof vaults, you still run the risk of losing them. Storage media can be damaged, files can be hacked online, and vaults can be lost when disasters strike; if you want to minimize the risk of losing important company data further, choose a good data recovery service company.

Know what backup type you need. You can't call them up and say: "I want to back up everything". You won't get what you pay for this way; worse, you may end up paying more. Do you need to back up the soft copies, or do you need some safe place to lock away your storage media? Determine what you want to back up, how much you should back up, and how quickly you need to recover lost data, among others.
Gather recommendations. This is the easiest and most efficient way to get the best companies in your area. You can get recommendations from trusted people, acquaintances, or online forums. Ask around for data management companies, their services, and their reputation; narrow your choices to three companies, at most.
Have a free evaluation. This way, you'll see the quality of their services for yourself. Did the company's representative simply take one look at your computers and give you a one-size-fits-all solution? Or were the computers inspected thoroughly before a detailed solution to your problem was rolled out?
Look at their success rate. Companies that specialize in the data recovery service Los Angeles companies can trust should not hesitate to provide you with references. Contact these references, and verify whether the company's claims are true. Certain cases, such as corrupted files or defective storage media, cannot be helped, so be careful with companies that claim to have a 100 percent success rate. Inquire about their data recovery process and the equipment; good companies, at a minimum, use class 100 clean rooms and careful methods to recover data.
Consider their trustworthiness. You pay for data recovery service Los Angeles companies offer with the understanding that you need to reveal some confidential company information to them at one point. Ask your references about any suspicious incidents, e.g. serious data theft, that may be linked to shady data recovery companies. To be on the safe side, find a way to monitor the data recovery process at all stages.
Secure your data, and secure your company's future. Consider efficiency, reliability, and trustworthiness when in search of the best provider of data recovery service Los Angeles has to offer. For more information, read voices.yahoo.com/how-choose-data-recovery-company-99595.html?cat=15.

6 Easy Ways to Make Your Website Tablet-Friendly

Ipad-illustration


Ux-magazine-0c394f3746

There are nearly 70 million tablet users in the U.S. alone, a figure that has doubled from the year before. This means that nearly 30% of the country's Internet users are browsing on a tablet device.
Tablet traffic to e-commerce sites grew by 348% from 2011 to 2012, overtaking smartphone traffic for the first time. With the tablet market as young as it is, its footprint is only going to expand.
This trend sends a strong message: If you haven't already, now is the time to prioritize your website's design considerations for tablet functionality. Ignoring this could negatively impact your website's overall conversion rate, return visits, sales and more.

What Is Tappiness?

When a website exhibits "tappiness," it's easy -- or even delightful -- to use on a mobile or tablet device. Tappiness encompasses smart use of space, text that is easy to read, logical interaction clues and large touch targets that allow visitors to navigate with confidence.

The large font sizes and wide touch targets in this design offer a positive experience, even when reduced in scale on a tablet.
The opposite experience exists when text is too small to read and navigation links are so close together that unintended navigation occurs. This adds time, complexity and frustration to the navigation experience, which will quickly drive away your visitors.

Small font sizes and narrow touch targets in this design prove to be much more difficult to read and use on a tablet.
While it may be ideal to redesign your website with a responsive layout for all devices, time and cost may inhibit you from a complete overhaul. But you do have other options. Here are some tips to help you improve the way tablet users experience your website, with just a few simple changes that you can make today.

 

How to Improve Your Site's Tappiness

Just a few subtle adjustments to your CSS can greatly improve legibility and navigation dexterity on a tablet.
1. Increase the size and margin for buttons and calls-to-action. The average width of the index finger for most adults translates to about 45-57 pixels. Why make your visitor work harder to find and tap the "Buy" button?

2. Ensure links and calls-to-action look tap-able without hover states. Hover states do not exist on a tablet. Style your text links to use a clear, contrasting color. And don't be afraid to use underlines for the default link state.

3. Increase font sizes for legibility. Bumping up your font sizes by a couple pixels or partial em's can make a difference. A little goes a long way.

4. Increase padding around navigation menu items. Try increasing padding by 5-10 pixels to start -- or more, if your design allows.

5. Increase margins on pages and content blocks. This improvement supports overall legibility and reduces visual complexity. Increased "white space" can result in the impression that your website's content is easier to consume, as compared to a website with crowded content.

6. Increase form field size and spacing. Make it easier for your visitors to tap and enter information into form fields. Improvements to your forms may make the greatest impact to your conversion rate.

As an added bonus, these simple CSS changes will likely benefit your desktop visitors as well. But, as always, be sure to run QA on your changes for all platforms and browsers before committing to them.

Great Examples of Tablet-Friendly Websites

Below are a few websites that exemplify tappiness. Try these out on your tablet as well as your desktop. Notice these sites don't employ separate layouts or versions for tablets. Yet the same site looks good and works well on both platforms.
Fitbit uses a healthy amount of white space coupled with large text and generously-sized touch targets.

Comcast's website offers large text and spacing. You'll also notice clearly indicated links, well-spaced navigation and sub-navigation and large, easy-to-use form fields.

While Skillshare could bump up the size of their body text a bit more, they do offer large, easy-to-use buttons for navigation and calls-to-action. There is also plenty of space surrounding content blocks.

It's no surprise that Apple's website has tappiness (after all, they did pioneer the design for hand-held touch screens.

Does your site provide tappiness? Check it out on a tablet device and see for yourself. Your website may be losing visitors, conversions, and money by creating an unpleasant experience for tablet users.
The good news is that you don't need to spend a lot of time or money to make tiny, incremental changes that will vastly improve your user experience on tablet devices. For many of you, that means money in the bank.
