A Wireless and an Almost Wireless LED Monitor from Samsung and AOC


Do you know that you can now do away with the clutter of cords and wire that usually comes with using flat screen displays with your computer or laptop? Well, if you’re like me who’s tired of all the ugly tangle of cord then you might appreciate what AOC and Samsung have come up for us. Yes, these two companies are currently selling a couple of neat LED backlit flat screen LCD displays that have eliminated this problem. Well, at least the Samsung has totally solved the problem with wireless technology while the AOC nearly got there. I will explain that one in a bit but let’s start off with the Samsung.

The Wireless Samsung C27A750X

This LED-backlit LCD flat screen monitor is basically a docking display and computer monitor rolled into one. It uses wireless technology to hook up with your laptop, notebook (or even desktop) so you can use it as a docking station and a display extension. This means you don’t have need to get a docking station so you could extend your displays. You just need this one Samsung! Definitely a boon if you use a small-ish notebook/laptop for your mobile needs but would want something bigger when you get home! It is 27-inch with a full HD (1080p) resolution so you’d get ample pixel space if you need it. Wireless connection for this unit is achieved using a USB adapter that you will need insert into one of your notebook’s USB ports. You could also hook it up via wired USB cable if any situation warrants so. And since it’s also a docking station, it comes with a sufficient number of the standard connectivity features like USB3, USB2, HDMI, etc. See following unboxing video for the Samsung C27A750X:

The Almost Wireless AOC E1649FWU

If you’re not really looking a monitor with docking capabilities like the Samsung then the AOC E1649FWU might be good enough if you could get over the fact that it isn’t really wireless in the same sense as the Samsung. But it does have one very neat capability; that is, it does not require a power cord. It gets all its power from the wired USB connection to your laptop/notebook. It’s value is in its portability and it works well as a presentation device. Just prop it up on a table and you can run your presentation. It has an auto-pivot feature to re-orient image depending on whether it’s in portrait or landscape position. Resolution is 1366 x 768 so it should be nice for casual viewing or showing of images but feedback from users indicate it’s really not for high-quality image or video editing work so be advised. Well it’s also way cheaper than the Samsung so features should be limited.


Packing more pixels into those flat screens with 4K!


The race to cram more pixels into those displays isn’t only limited to smart phones, tablets or computer screens as it has also benefited the ubiquitous television. If you think we’re stuck at HD (high-definition) then I guess you’ll be happy to know that we’ve actually moved on from that by what many considers a big leap in pixel count— about 4 times more pixels, to be more precise, compared to the standard 1080p HD television.

What is dubbed as 4k television, otherwise known as Ultra HD (UHD) flat screens with resolutions of 3840×2160 to 5120×3200 depending on the aspect ratio (HD resolution is just 1920×1080), has actually been around for a bit of time but I’ve not really paid much attention to them since they’re really still pretty expensive (the way LCD flat screens were when they were new in the market). However, the recent Consumer Electronics Show (CES 2014) has made developments in the 4k arena a bit harder to ignore with some cool demonstrations of head-turning TV displays that are reportedly bound for the consumer market— all of them packing some mean pixel firepower!

Take, for example, the stunning display of curves from Samsung and LG with their respective 105 in. curved screen TVs which they both claim are the world’s first. Both TVs sport Ultra HD pixel count levels with 21:9 ratio which makes it pretty wide indeed and will be a true centerpiece of any living space. These two same companies also showed prototypes of a TV screen that bends. Yep, bendable TVs may be in your living rooms sooner than you think, provided that you can afford them at their first mass market release.

Another interesting development is the fact that companies are truly making them televisions smarter for a more interactive viewing experience by putting in more sophisticated operating systems (OS). LG showed off a new flat screen unit installed with a proprietary OS called WebOS (which they actually acquired from HP) which can make the TV access more than traditional TV shows as it can also show Internet content and can be used as a communication device as well (e.g. using Skype, etc.). Hisense also showed a TV installed with its own version of Google’s Android OS which isn’t really surprising as it isn’t the first non-smartphone device that got “Androidized” but is still, I think, a clever way to innovate more on the smart TV experience.

But the best news is yet to come as one of the best developments all in all is the price war trend developing among these top companies. Vizio beat them all to it by releasing the first sub-$1,000 unit which, incidentally, is also their very first offering on 4K! This is a 50-inch model which is indeed pretty surprising considering the current price levels of TVs of such size from the bigger brands (Samsung, Sony, etc.). While lower prices have been seen in smaller, relatively unknown brands, such trend creeping into the Samsung or Sony territory would be welcome development indeed.

Electronics companies are obviously betting on the 4k as the wave of the future but is their bet well-founded? Is the market adopting? Reports indicate that it’s slowly doing so and that things are also slowly happening in other 4K-related devices as well. Some new set-top boxes are adopting 4K as well which bodes well for those wondering if 4K content will be supported well into the future.

Will you buy 4K anytime soon?

52-Inch Samsung LCD TV Repair Video for Fixing Power-up Failure


Here is another video showing a step-by-step procedure on how to fix a Samsung 52” LCD TV having some power issues, which I am seeing is one of the most common issues people encounter after a while of using their flat screens. This is actually a very similar to the Polaroid LCD TV problem I posted about a while back.

This problem is characterized by the failure of the unit to turn on. Trying it a number of times might eventually do it but if you leave it as is and not do anything to fix the problem, it may get worse and stop turning on altogether.

Like the Polaroid TV problem in my previous post, the problem can be traced to capacitors gone bad and the video will show you how to get to them safely and replace them using very simple tools, one of which is a soldering iron. Operative word here is “safely” so if you are in doubt whether you can do this due to safety concerns, I’d suggest you just bring it to a professional.

This fix can also be performed on other Samsung models in the same line like the LN46A750 46” LCD TV and will cost you just around $15. You will definitely get charged more than that if you have it done at a repair shop.

As usual, if you are interested to learn more about how to repair LCD TVs, I’d recommend checking out this LCD TV repair course by Kent Liew.
