UHD TV by Minh-Tam Doan

Ultra High definition (Ultra HD)--four times better resolution than full HD--is a true breakthrough. LG brought the first Ultra HD TV into the market last fall and has just developed second generations.

These new TV’s are un astounding 2160p give a resolution four times better than full HD. The second generation LG’s are going at a retail price of $5999.99 for a 55-in. and $7999.99 for a 65-in. display.

As Taylor says, “As screen sizes get larger and as consumers buy larger and larger screens, they are going to demand more resolution.” This means that Ultra HD, or 4k, will enable bigger screens at clearer resolution.

The 4k TV sets will upscale most HD movies, and Hollywood is already developing their movies in 4k too. To add on, 4k cameras and camcorder are now on the market allowing the production of 4k films and clips.

Currently, Sony has a $24,999.99 84-in. Ultra HD TV as well as a 55-in. at $4999.99 and a 65-in. at $6999.99. Along with this Sony has a 4k media player preloaded with 10 4k films and a unlimited 4k download service at around $7.99 to $24.99 a month.

"Ultra HD TV also provides greater depth to picture quality, giving a more immersive experience," says Sweta Dash, senior director of display research and strategy at research firm IHS. " And with upscaling technology, consumers can see better picture quality even when watching (current) HD content. Learning from past experience, many TV brands are actively working to provide Ultra HD content, either through upscaling or through the creation of proprietary UHD content."

Ultra High Definition TV’s really do hold the future for HD TV’s.

Preventing Touch Screen Smudges by Minh Tam Doan

A person is on an Android tablet after he eats garlic bread. His cousin manages to get ahold of the the tablet and figures out the Android passcode. He was puzzled at first, until he raised the screen into the light. He saw the smudge marks he made with the oil from the garlic bread, and wondered how to prevent this.

Because of the pattern feature of the Android lock, it is relatively simple to redo the code by looking at the smudges. In fact, you can recreate the code 90% of the time according to the University of Pennsylvania.

Of course you can use a pin code to lower the risk or go through the hassle of wiping the screen every time to prevent an intrusion. Or you can use the app called Whispercore. According to Lifehacker, “it arranges the numbers vertically and it then asks you to wipe the screen in order to unlock the phone, obfuscating the original smudges. If you use a pattern to lock your phone, after you input the correct pattern, it's a screen full of stars. Swipe the highlighted stars to unlock the phone, again obfuscating the original smudge pattern.” This then acts a reminder to wipe your screen.

Another thing you could do is to use more than four digits. For example, if you have a six digit code, you can use the same digit more than once so that the hacker will have trouble finding the amount of digits there are.

According to Breakthrough teacher Edwin, it is “an issue we should address...always make sure to erase our code.” Also, he recognizes that “in regular school, when your classmates steal your phone, they can easily hack it.” Edwin finds that this problem is common in school as this is where your phone can be stolen easily.
