Through a 3D glasses to get the best 3D experience

April 8, 2012 web Tablet PC & Digital

With the rapid development of 3D technology, the 3D glasses is taking over a large market. Especially, as more and more HDTVs are popular with families and becoming a part of household, the 3D glasses is required when people are in the fornt of HDTVs. So The universal 3D glasses are the best answer to how to get the best 3D experience

In the previous time, Most glasses were only compatible with one brand of TV. While at new times,the universal 3D glasses has changed all of that. For example, at hisgadget.com, Universal 3D  Infrared Active Shutter Glasses for 3D HDTVs – Rechargeable is compatible with Samsung , Sony, Panasonic, Phillips and Toshiba. The glasses will automatically sync with whichever TV you have, which means there is no programming whatsoever. All you need to do is turn them on and you can begin enjoying your 3D content.

The glasses are also unique because you can be synced up on one TV (let’s say a Sony), and then if  you walk over to a Panasonic TV the glasses will automatically recognize the new signal and sync immediately. This is important if you have two 3D ready TVs and you want to be able to buy one pair of glasses that will work with both. Plus, if you upgrade your TV in the future, or change brands, you are guaranteed to still have a working pair of 3D glasses.

This kind of universal 3D glasses are specifically designed to fit great over prescription glasses. The nose piece and stems have a silicone rubber padding for added comfort. These help the glasses to stay on your face when you’re moving your head. Some other cheap 3D glasses have a tendency to slide off your face easily if you move or lean forward. While this one is easily the most comfortable universal 3D glasses currently available.

The glasses also feature a physical on/off button with an auto shut-off feature. This means you don’t have to wonder whether the glasses are turned on or off anymore. Having a physical button allows you to turn them off easily to save power. If you do happen to forget to turn them off, the glasses will automatically shut themselves off which preserves battery life.

All in all, Your 3D experience will most assuredly be improved by going with this high quality pair of 3D glasses.

5 Common Mistakes that Shorten the Life of Your Laptop Computer

October 24, 2011 web Tablet PC & Digital

A laptop computer can be a pretty big investment.  Even with prices falling dramatically, replacing a laptop can be quite expensive.  Laptop computer repair isn’t any cheaper unfortunately.  Here is a list of 5 of the most common mistakes that can send your laptop to an early grave.

1) Using your laptop near liquids - This is pretty self explanatory, but is regularly overlooked.  Don’t set anything liquid on the same surface as your computer.  If you must ignore this rule, drink only water and keep the lid on when you aren’t actually drinking.  If a spill does happen, water is a lot easier to recover from than your toddler’s favorite juice.

2) Closing the lid and immediately shoving the laptop into a backpack/briefcase - Most laptop computers are set up from the factory to auto-hibernate when the lid is closed.  Shutting your computer down properly is the best way to go, but if you are in a hurry, at least wait for the computer to turn off before you move it.  The platters in your hard drive spin at around 7200 RPM and the heads hover less than a hair’s width from the surface.  Even the slightest shock or bump can cause the drive heads to crash into the platters destroying the drive along with all of your data.  Even if you don’t cause a head crash immediately, you can significantly shorten the life of the drive.  Be patient, and you will avoid a lot of potential problems.

3) Leaving the AC Adapter (Power Cord) plugged in while storing/carrying your laptop - The power jacks in today’s cheap (ie. low quality) but popular laptops (Yes I mean you HP & Acer) are not soldered very well, and if mistreated, break very easily.  This type of laptop repair is difficult, therefore not cheap.  DC jack repair usually runs about $150 depending on the computer repair shop that you take it to.  The best way to avoid needing this repair is to unplug the power cord while you are not using it in order to avoid any kind of unneeded stress on the jack.

4) Using after-market/generic power cords - If you don’t follow the advice in #3, and are one of the lucky people who happens to break your actual power cord but not your computer, it can be really tempting to buy one of the $3 generic power cords on Ebay.  This is not a good idea because inexpensive AC adapters tend to not run at the exact voltage or amperage that your computer requires.  Over time, this incorrect power source will damage and/or wear out components completely destroying the computer.  Don’t end up replacing a $600 computer early because you tried to save $30 on a power cord.  Stick to genuine OEM ac adapters and you can avoid costly laptop repairs.

5) Using your laptop on your lap (or other soft surfaces) - Heat kills electronics, and your laptop computer needs to be able to “breathe” in order to cool itself.  Most laptops “breathe” through the bottom.  When you use a laptop on your lap, bed, or carpet, you cover up the air vents that your laptop needs to cool itself.  Not to mention you can develop a nasty problem known as Toasted Flesh Syndrome from using a laptop on your lap (this is why all “official” sources now call them notebooks instead of laptops to avoid lawsuits).  Always set a notebook computer on a hard surface that will leave the air vents unobstructed.  Consider buying a cooling pad for your laptop as well.  This is essential for computers that are easily damaged by overheating (anything from HP/Compaq).

Laptop repair can be expensive, but fortunately, most problems can be avoided with a little common sense.  One of the biggest mistakes that people make, but we didn’t cover, is thinking that you can get a quality laptop computer for less than $600.  Buying quality up front will also go a long way towards making your computer last longer.  This is a topic for another article though.

Active Displayport Adapters vs. Passive Displayport Adapters

Active Displayport adapters vs. Passive Displayport adapters

There seems to be a ton of confusion around here about

1) what is required for eyefinity,
2) what an active adapter is, and
3) the difference between active and passive adapters.

I am making this thread, hopefully to clear that confusion.

Examples of passive adapters:DisplayPort Male to HDMI Female Converter Passive Cable

Examples of active adapters:DisplayPort Male to VGA Female Converter Active Adapter

1) Eyefinity requires an ACTIVE adapter to enable a third monitor on HD 5000 cards. Passive will NOT work, except for the first two monitors on the eyefinity 5 and eyefinity 6 cards. For the other three/four monitors, active is still required. A quick explanation of why is because DVI/HDMI requires a special clock, which the card is only able to provide two of. Displayport does not use this clock, so ATI used it as a workaround.

2) An active adapter converts a true displayport signal into DVI/HDMI/VGA/whatever else. It will have either a converter chip or a DAC built in to do said conversion. Contrary to popular belief, they do not need to have a usb power connection, in fact there are many that do not.

3) This is the big one I have been seeing a lot lately. The difference between active and passive is simple.

Passive adapters are merely a cable to go from displayport to DVI/HDMI/VGA/w.e. The video card detects the monitor as such, and outputs the required signal (DVI/HDMI/VGA). This does require one of the two aformentioned clocks, hence why they do not work with eyefinity cards.

Active adapters, on the other hand recieve a displayport signal from the video card, and convert it to DVI/HDMI/VGA. They will always have some sort of onboard DAC or video converter chip which they use to convert the dp signal. Lately, most everyone has been referring the DAC ones (which are the converters that go DP->VGA) as ‘passive.’ This is not the case.

How to Clean a Laptop Screen Yourself

August 18, 2011 admin Tablet PC & Digital

Laptop repair could cost much so that it is essential to take a good care of the laptop screen . The best way to prolong life of your laptop and its screen is to use it with a proper care.

  1. Make a special cleaning solution or use commercially available cleaning kit designed specifically for use on LCD screens.
  2. If you do not use a special commercial cleaner, the ideal solution is plain distilled water. If more heavy cleaning is needed a 50:50 mix of white vinegar and distilled water can also effective.
  3. Make the cleaning mixture and keep it in a small container nearby.
  4. Shut down your laptop before cleaning.
  5. Apply the solution to a very soft cotton cloth; it is better to use lint-free lens wipes instead of a cotton cloth. A large cloth is best, since it will help to reduce the risk of leaving streaks across the screen from finger pressure.
  6. Soak cloth in the cleaning mixture, then wring it out completely. It should be damp but not wet. Wipe the computer screen down gently in long motions rather than hard circles. Dry the screen with a dry cloth.
  7. If your screen is damage or you prefer to replace with better one, you may find third-party companies on the market that are selling laptop screens since most laptop manufacturers charge too much.

Things You Will Need

  • Distilled water
  • A soft cotton cloth

Warnings

  • Do not use paper towels, tissues, or napkins – they can contain wood fibers that can scratch the screen.
  • Use either a soft, lint free dry cloth or a commercially available cleaning kit designed specifically for use on LCD screens.
  • Using a lint-free microfiber cloth is best, an old cloth can introduce dust.
  • Avoid using products such as Windex because these contain ammonia and it can degrade the screen.
  • Do not use any products that contain alcohol, ammonia, or other strong solvents. Do not use soap.
  • Do not spray any liquid directly on the LCD screen.
  • It is better not use tap water, especially, if the water in your area is rich in minerals.
  • Use only enough pressure to hold your cleaning wipe on the screen. NEVER press hard, scrub, or scour when cleaning an LCD screen.
  • If in doubt, test a small area of screen first.
