And now they have unveiled two new 3D plasma TVs for the US market. The C680 is official now and C490 should be in stores soon as a low-price 3D alternative.<br /><br /><p align=center><a id="thumb" href="pictures/samsung3dplasma-1l.jpg" class="highslide" rel="highslide"><img class="imgresponsive" src="pictures/samsung3dplasma-1.jpg" alt=â€ťSamsung 3D plasma" title="Click to enlarge" /></a><br><i>Samsung 3D plasma</i></p><br />C680 will be available in 50 inches called PN50C680 and will incorporated a 1920x1080 3D-panel with a dynamic contrast ratio spec of 2,000,000:1. It's based on the active 3D technology that requires active shutter glasses.<br /><br /><p align=center> <img class="imgresponsive" src="pictures/samsungc680-1.jpg" alt="Samsung C680 3D plasma"><br><i>Samsung C680 3D plasma</i></p><br />The panel is also slimmer than most plasma-TVs, although not as slim as the flagship Samsung plasma models. C680 comes with 4 HDMI inputs and Samsungâ€™s Internet and DLNA AllShare functionality. Samsung has also integrated a USB port for media playback and a game mode to reduce input lag.<br /><br /><p align=center> <img class="imgresponsive" src="pictures/samsungc680-2.jpg" alt="Samsung C680 3D plasma"><br><i>Samsung C680 3D plasma</i></p><br />The cheaper C490 series is the first 3D 720p plasma-TV from Samsung. It will feature a new so-called e3-panel and 3 HDMI inputs. No Internet or DLNA has been confirmed for this model.<br /><br />C490 will be available in 50 inches called PN50C490. The 3D glasses will have to be bought separately.<br /><br /><h3>Official now</h3>C680 is official on the <a href=http://www.samsung.com/us/consumer/tv-video/televisions/plasma-tv/PN50C680G5FXZA/index.idx?pagetype=prd_detail&tab=features target=_blank><b>Samsung US site</b></a> now. C490 is still not official. No prices have been mentioned.<br /><br />The TVs have only been confirmed for US launch but I think itâ€™s safe to assume that Europeans can expect to see some announcements during the huge consumer electronics fair IFA 2010 in Berlin this September.
