Television Type

The type of technology used to produce the screen images. LCD, DLP, Plasma, LCoS, and CRT are the most common. 2 newer technologies include LED and OLED which use light-emitting diodes (LEDs) as a backlight, as opposed to conventional LCD TVs, which use cold-cathode fluorescent lamps (CCFL) for a backlight.

LED technology integrates LCD display technology with LED backlighting. On LED television, both LCD and LED will be selected here.

3D Ready
This means that the television is compatible with 3D images. Some televisions will require special glasses to view the 3D images, while other TVs can display the image without the necessity of glasses.
Screen Size
The screen size dimension is measured diagonally in inches.
Aspect Ratio
The standard ratio of 4:3 (width:height) is one that most are familiar with; however, today we're seeing more models with widescreen 16:9 aspect ratios, which closely matches the most common movie theater screen ratio and HDTV broadcasts too.

Selectable aspect ratio means that the user has the option to choose which aspect ratio they would like. This feature is usually found on televisions.

Selectable Aspect Modes
This is the number of aspect ratio modes that the television or display is capable of. Having multiple options here allow the viewer to choose the best aspect ratio for them.
Resolution (pixels)
A display's pixel resolution defines its ability to resolve fine details. Digital TVs and projectors measure screen resolution in pixels. The higher the resolution, the more detailed the picture will be.
1920 x 1080 
The level of brightness; measured in candela per square meter (cd/m2), a calculation that measures light intensity emitting from the screen. The higher the value, the brighter. Some manufacturers will measure brightness in NIT. These measurements are equal. 1 cd/m2 = 1 NIT.
500 cd/m2 (NIT)
Dynamic Contrast Ratio
This is the maximum contrast ratio that the display is able to produce. Typically, the dynamic contrast ratio is about 5x the normal, or static, contrast ratio.
Refresh Rate
Refresh rate is the number of times in a second that the display will draw the picture on the screen.
240 Hz
Response Time
In relation to LCD monitors, the response time is the amount to time it takes for a pixel to go from black to white, and then return to black again. The time is measured in ms, or milliseconds. The lower the response time, the smoother the display can playback video. A high response time results in less blur and a crisper image.
2.4 ms
Viewing Angle
This represents the angle at which the monitor can best be viewed at.
178 °


WiFi Capable
This feature allows devices to download new software updates, stream video content through various services, or connect with BD-Live features wirelessly when connected with a compatible wireless link.
Video Broadcast System
Most cameras and displays will be compatible with a NTSC video broadcast system. Others will be compatible with a PAL system. Many units will be compatible with both.
ATSC Compatible
ATSC is the new high definition format that will become the standard in 2009. It will be replacing the former NTSC television system.
QAM Tuner
A QAM tuner allows select digital televisions to receive a digital signal without the use of a digital set-up box.
HDTV Compatibility
This means that the television, projector, or monitor is capable of receiving and playing back a high-definition signal.
Display Format
High-definition televisions will display the image at 1080i, 1080p, or 720p. To be considered full HD, a television must display at 1080p.

Standard televisions will display the images at 480i or 480p. This means that there are 480 horizontal lines that create the picture.

CableCARD Compatible
CableCARD is a wireless card that allows the viewing of digital cable television channels on digital video recorders, personal computers and televisions. They do not require the use of equipment provided by a cable television company.


Number of Subs/Speakers
This value represents the number of speakers or subwoofers that the enclosure accommodates.
Total Peak Power Output
The total peak power output is measured as the wattage per channel multiplied by the number of channels, and is calculated at the lowest level of operating impedance.

It is measured during a brief musical burst, such as a sudden drum accent. Some manufacturers display peak power ratings on the face of their products to increase the appeal.

The RMS power rating is more accurate, and we recommend using it for product comparison.

20 watts
Premium Surround Speakers
This means that the television has high quality speakers built-in that provide a surround sound feel. While this feature does not replace a 5.1 or 7.1 Dolby surround sound system, it does have a notable difference above the standard television speakers.

Awesome TV

August 10, 2010

I Love this TV. I purchased this approximately 6 months ago and it was delivered within 1 week - no tax and no shipping! Saved over $400 by purchasing here rather than my local Best Buy store. The t.v. is crystal clear with a beautiful display. Easy to keep clean. Totally recommend this t.v.!
