We haven't had a chance to fully test this product yet, but we've assembled this helpful overview of relevant information on it.
The Samsung UN46ES7100 is the smallest of the UNES7100 series with a 46″ screen. Although the UN46ES7100 is the smallest, it includes all of the features the larger TVs have. These features include Edge LEDs, a 0.2-inch-thin bezel, a 240Hz refresh rate as well as 3D capability. This is the cheapest of the three high-end LED TVs announced at CES, but this is because it lacks the Smart Interaction the 7500 and 8000 series TVs have. This TV does feature Samsung’s “micro-dimming plus” local dimming which allows the TV to dim certain sections of the screen independently. The Samsung UN46ES7100 does not have an announced price as of yet but is expected to commence shipping in April.

Digital Trends’ TV Buying Tips:
Should I worry about viewing angle?
Absolutely. All LCDs will distort when viewed from extreme angles, but the degree of distortion and the angle it starts to occur at varies from TV to TV. If you plan to pack a dozen people in front of a single TV for entertaining, viewing angle will make a huge difference for the unlucky few who get scattered off to the sides. Most manufacturers will state viewing angle in degrees (for instance, 160) in the specifications for a TV, but be warned: methods for measuring this very subjective figure vary, and we can guarantee most companies opt for the most generous figures. When possible, try to evaluate it yourself in person, or read hands-on reviews that can offer anecdotal evidence, rather than relying on easily-manipulated numbers.
What inputs should I look for?
A final consideration when buying a new HDTV is what you can connect to it. Make sure there are ample HDMI (High-Definition Multimedia Interface) ports to connect multiple components, such as a cable/satellite receiver, video game consoles, DVD/Blu-ray player, camcorder, and so on. At least three or four such ports is a must. A convenient bonus is when the TV also offers a USB port to connect a Flash thumb-drive or external hard drive full of music, photos and videos, or a SD or Memory Stick card slot that lets you insert a compatible card that contains photos and videos. If you think you’d like to connect your computer to the television for big-screen web surfing, look for one with PC connectivity. Many TVs today offer these additional features.
What is a LED backlighting?
Traditionally, LCD TVs have used compact fluorescent (CFL) tubes placed behind an LCD panel to provide the backlighting that literally lights up the screen. More modern LED TVs replace these tubes with clusters of light emitting diodes – LEDs.
When LEDs are placed at the edges of the screen, as CFL tubes traditionally were, TVs can be made significantly thinner, and LEDs use less power than fluorescents. The most inexpensive LED-lit HDTVs take this approach.
However, the biggest advantage to using LEDs is realized when they light the screen in a grid from behind. Sophisticated electronics vary the intensity of every LED in accordance with action on the screen, making dark areas of the image darker, and bright areas brighter. This effectively increases the contrast ratio compared to uniform lighting. Although it also increases costs, many people believe this type of LCD is the first to truly rival plasma on black levels.

What resolution do I need?
All consumer HDTVs break down into either 720p or 1080p resolution, which represents the number of horizontal lines in the display. More is obviously better here, but at small screen sizes – like 32 inches – many people find it hard to distinguish the benefit of 1080p resolution. As our guide to screen size points out, viewing distance can also play a factor: The closer you sit, the more you’ll appreciate higher resolution. In general, many people start to see an obvious difference between 1080p and 720p as screens sized 40 inches and up.
Also take into account that much of the content available today doesn’t take advantage of full 1080p resolution. Many shows still broadcast in 720p or 1080i. Technically only Blu-ray discs and digital, non-video sources (like a PlayStation 3, Xbox 360, or PC hooked up to the TV), really offer true 1080p content. This makes 1080p a no-brainer if you want to play Mass Effect 2 with the most detail and watch Star Trek on Blu-ray, but less essential if you just play to watch standard over-the-air broadcast material.
Which other panel specs should I pay attention to?
In short: brightness, contrast, and refresh time.
Brightness is measured in Candelas per square meter, or cd/m2. A typical figure, for instance, might be 500 cd/m2. More is always better, especially if you plan to plant your TV in a bright room where the screen will have to overcome other light sources.
Contrast is measured as a ratio of the brightest white a TV can produce, over the darkest dark. For instance, Insignia’s NS-L42X-10A offers a 4,000:1 contrast ratio. More is also better, but beware of “dynamic contrast ratios,” which use unrealistic measurement conditions (the brightest white is measured with the backlight set to full, and the darkest dark with the backlight to minimum, even though those levels could never occur side by side on the same screen) to inflate the number to levels like 2,000,000:1.
Refresh time is measured in milliseconds, such as 5ms. Lower is always better, and will prevent the “ghosting” that can sometimes be seen in fast-motion video.
