Samsung TV Evaluation

Monday, December 17th, 2012

On this review, we’re taking the 60-inch Samsung UN60ES8000 for a field-test to determine how brand new features such as voice control, motion control and face recognition work in the real world.

Certainly, the graphic quality is a critical aspect for any TV purchase. Sadly, I dont have an environment where the lighting is controlled neither the tools to determine color precision (spectroradiometer), but again, most of the people dont adjust their own monitors, have a lab in their living room or make use of 5000k white lighting. Instead, Im going to concentrate on real-world stuff like how the television acts in direct sunlight, and to external light sources etc. This is pretty subjective, but at least you know where I come from.

I found the Samsung ES8000 to make a great picture quality with plenty of brightness (even in direct sunlight) and I found the colours reproduction to be great not over saturated or otherwise. It would be nice to determine this with a real benchmark (gotta like science), yet I have seen numerous TVs and worked for 15 years in computer graphics, so I have some knowledge of what precisely graphic quality means.

One thing that is rarely scientifically measured is the amount of image processing which occur in those tvs. Samsung too does employ numerous filters to the picture coming from video resources (cable TV etc), but I need to state that they dont overdo it. Many TV makers utilize too much Sharpening or colour vividness, however the Samsung ES8000 series looks good out of the box and thats significant simply because most of the people dont want to tweak the settings and have no great calibration to do so. You can consequently tune according to your tastes, should you want to.

Remarkably, I found the 60 UN60ES8000F to look slightly more blurry -in relative terms- than my 55 Samsung UN55D8000YFXZA. This is normal as it shows the same 1080p image on a bigger surface. This shows that large-size TVs would eventually require something much better than 1080p resolution (1920◊1080 pixel). In absolute terms, the majority of people would call the image crisp, and unless youve seen many 4K demonstrations like we did, its difficult to complain about 1080p on a 60. But if you come from a 50?, you may want to know this bit of information.

Setting Up Your TV The Best Way

Friday, December 14th, 2012

You prefer viewing television. You only bought a new HDTV, hooked it up, and only want to sink into your couch and luxuriate in that beautiful HD picture. Which is perfectly sensible. You have to be able to just press a few buttons and access hundreds of channels and watch them in high definition with total convenience.

But unless you set things up properly, that may not be easy to attain. An incorrect cables, picture modes, standard-definition channels, and even screen cleaner may adversely affect your high-def gratification. Thankfully, it only takes a few easy steps to get things proper. Here are 6 of the most common HDTV viewing errors, and how one can fix them in a snap.

Not Utilizing HD Connections We have seen this one too many times. Joe drops a grand on a brand new HDTV, takes it home, and sets it up just to find that the picture looks much softer and less detailed than it did in the store. This isn’t mainly because the set is malfunctioning, or Best Buy used black magic to optimize the picture to get him to buy it. Joe connected his set-top box towards the tv with a composite video connection, or he simply screwed the white coaxial cable from his set-top box right into the back of the TV.

Simply because your HIGH DEFINITION TV can display 1080p HD video does not mean it always displays 1080p video. The resolution of the video source is essential, but so is the connection you use. There are lots of different ports in the back of HDTVs, Blu-ray gamers, game systems, as well as cable boxes, and many of those selections will get some type of picture on your screen. It just might not be the best picture.

The simplest way to connect your video source-cable or satellite box, game console, or Blu-ray player, for exampleto your HDTV is HDMI. That is the trapezoid-shaped port-most HDTVs have trapezoid-shaped port-most HDTVs have a minimum of 3 of them.

Up to 1080p video and 7.1-channel audio can be moved through one cable, providing the best picture and sound with the quickest connection. If you run out of ports, or if your video source does not have an HDMI output, you can utilize component video cables, which commonly top out at 1080i and also deliver stereo audio; video will still look good through 5 cables (three for the red, green, and blue color channels, and 2 for the audio channels).

Taking a Look at LED HDTV Technology

Monday, June 27th, 2011

Today’s televisions can be completely unrecognizable from their previous variants within the marketplace. In the past, the more hi-tech TV’s which were around were the bulky, black and white models. But these days, thin units that includes flat, colourful displays are already the trend. Tv innovation could possibly have just attained its highest with the arrival of such high-definition TV’s that can generate realistic as well as high-resolution pictures. HDTV’s can be considered as being a global phenomenon, with various manufacturers introducing superior-quality products at each launch date. And the latest addition to this huge series of remarkable technology is the LED HDTV. This particular type of tv offers home entertainment and technology similar to no other.

LED or Light Emitting Diodes is basically a technology designed to enhance the backlighting of LCD HDTV’s. While LCD TV’s integrate Cold Cathode Fluorescent Lamps (CCFL’s), LED technology works by using numerous LED tubes set up all around on the side or at the rear of the television screen. This lets the display to provide lighter and deeper colours for images and due to this, the pictures come off as far more vivid as well as lifelike. All these (blank) tubes also permit such television sets to become leaner compared to other kinds of HDTV’s, because the source of light is usually strategically located right behind or on the edges of the display and the over-all sizing of the television drastically decreased. With a few diffusion layers and light pipes, more streamlined LED HDTV’s is possible.

There are also LED HDTV’s which are only an inch thick. LED and LCD HDTV’s tend to be different with one another due to their backlighting, with the former using LED lights and the latter making use of fluorescent tubes. With this, LED TV’s provide much more attractive and innovative capabilities compared to their LCD counterparts do. A LED HDTV is practically simply an LCD TV that integrates the LED technology. Nevertheless, most electronics manufacturers often choose to refer to these items as distinct types of tv set; nonetheless, in doing so it creates further misunderstandings to customers.

LED backlights can in fact appear in 3 kinds, each one featuring its own layout of LED tubes inside the Television. The first kind is Dynamic RGB LEDs that will display colours at excellent contrast ratios. The LED tube backlights in this particular design are placed in the rear of the panel. Another one is full-array LEDs where the backlights are positioned at the rear of the screen. Even so, full-array LEDs are incapable in presenting a much faster image display as its LED tubes can’t brighten or dim separately. Last but not least, there’s also the Edge LEDs which offers a more uniformly distributed colour through the entire screen. Edge LEDs can easily produce images more precisely since their backlights are spread around the display screen.

Because LED’s are separately controlled it is simple for the LED tubes to automatically turn off to show the deepest shade of black for its pictures, while on the other hand, lighten up smartly to brighten the screen and deliver the proper contrast. Both of these functions of the LED tubes enable them to produce a remarkable contrast ratio all through the screen. This equates to superior, more dynamic and defined images.
