We haven't had a chance to fully test this product yet, but we've assembled this helpful overview of relevant information on it.
Samsung’s PN42C450 offers a 42″ Plasma screen with 600Hz Sub-field motion that creates crisp clear images. The Samsung Clear Panel and E3-panel filters ensure crisp clear images even from off-angle reflections that would normally blur the image. Connect a thumb drive or digital camera and view your images and videos with the USB port and easy to use menu options. Two built-in speakers provide 10 watts of surround sound – standard in most TVs. Three HDMI ports standard and exceeds Energy Star requirements. The resolution comes in 720p .

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.
Do I need an ATSC tuner?
If you plan on watching, free, over-the-air programming, then yes. As of 2009, all over-the-air broadcasts use the ATSC standard. Pretty much all HDTVs manufactured over the past few years will include this feature.
LCD or Plasma?
Debating between LCD or plasma can almost get as subjective as debating between chocolate and vanilla. But unlike the never-ending ice cream debate, there actually is a superior TV choice, depending on how you plan to use it.
Check out some of our previous guides on the subject to get a better look, but in short, plasmas use more electricity, come in bigger sizes, have deeper blacks, don’t suffer from motion blur, and offer an unlimited viewing angle that’s best for off-axis viewing. LCDs are more energy-efficient, have fewer problems with glare due to their matte screens, can hold an image for hours or days without suffering “burn-in,” and generally look brighter.
What are widgets?
Many of the top television manufacturers – including Sony, Sharp, Panasonic and Samsung – include Ethernet jacks on the back of their premium televisions for high-speed Internet connectivity (or in some cases, have integrated Wi-Fi for wireless connections). TV viewers will then use the remote to select “widgets,” graphicalicons on the screen that plays relevant (and customized) content ranging from YouTube videos and Flickr photo galleries to local weather, news, sports updates and stock quotes, usually delivered by Really Simple Syndication (RSS). Even more exciting is the partnership between Netflix and various TV companies, such as LG and Sony, allowingtelevision viewers to access tens of thousands of movies on-demand, many of which are in high-definition.
