The quest for the perfect TV has been around about as long as "rabbit ears" and while technology has changed, the desire to have your TV look good, perform good and offer some nice features has stayed the same.  Today we have the LN40A650 TV from Samsung on the bench and give this 40" FullHD 1080p unit a test drive.  This is an LCD TV that appears to be backlit by CCFL's and offers a dynamic contrast ratio of 50,000:1.  It has a very wide viewing angle and a 4ms response time to boot.  What sets this apart - other than the "Touch of Color" is the presence of an Ethernet port and the ability of the TV to display RSS feeds such as news, weather and stocks.  While a 40" TV is probably considered small by quite a few people in this day and age, it is a perfect size if you have a smaller room and want other things to be the focus of your entertainment.

Before we really begin let's take a quick refresher course on LCD TV technology.  A flat panel LCD is really a type of projector although not really recognizable in the traditional form.   To generate the image that you see from your couch, fluorescent tubes have been used to shine light through a Liquid Crystal Display (LCD).  The LCD panel is used to filter the light that reaches your eyes.  Think of it in a very basic sense as a bunch of shutters that open and close.  Using a fluorescent tube produce the light is a very rough approach and it results in a lot of wasted light as well as a lot of light bleeding through when you want a black color.  With that being said, let's jump on in.

Due to the much slimmer design of the TV over earlier units, the box that the LN40A650 comes in is actually quite slim and is easily managed by a person with gorilla arms.  The overall weight of the unit is much less than my own 40" unit that features a heavy metal stand, aluminum bezel and more.  The Samsung feels like a feather-weight in comparison.  Although packaging was a bit light, the TV arrived in good shape - thanks to Fedex and our local Sears.

Of all of these specifications the 50,000:1 Dynamic Contrast ratio is the most interesting.  You will notice that this number is far greater than the typical 10,000:1 or 5,000:1 contrast ratio that is typical of other LCD TVs.  The other specifications are fairly normal and there is nothing else that is particularly noteworthy.
