As has annoyingly become the norm with Dell LCDs, the outfit has seemingly just thrown three new ones onto the world’s platter tonight with nary a peep from its press line. Up first is the 23-inch ST2310 (shown above), a slick widescreen panel with a Full HD (1,920 x 1,080) resolution, narrow bezels, a curved rear, DVI / VGA / HDMI inputs, 250 nits of brightness, a useless 50,000:1 dynamic contrast ratio, five millisecond response time and audio in /out ports for good measure. The 22-inch E2210H and 20-inch E2010H (shown after the break) both tout an all-business motif, with the former pushing a Full HD native resolution and the latter handling just 1,600 x 900 pixels. The whole trio looks to be available right now, with retail marks set at $229, $199 and $139 in order of mention.

Having recently refreshed its G-series of monitors, BenQ is back for more with an update to its pricier E-branded panels. The pair of new models come with the SensEye 3 auto-calibration sensor, which corrects contrast, color and clarity according to the mode you choose. Set for worldwide availability this month, the 21.5-inch E2220HD and 24-inch E2420HD both come with 1920 x 1080 resolution on 16:9 displays, 300 nits of brightness, 1,000:1 contrast ratio, and a “class-leading” 11 ports that include four USB, two HDMI, a DVI and a VGA input. The external redesign is highlighted by a side-mounted power button, sure to appeal to — well, just about anyone. Click through for higher resolution shots, including a close-up of that Vaio TT-inspired button.

DisplayPort may still have some ways to go before it’s widely accepted as the next HDMI, but with more and more outfits now pumping out panels with these very sockets, we reckon that wide market recognition is nigh. Take NEC’s MultiSync EA231WMi for example, which boasts a 23-inch LCD, four-way swivel stand, a two-step ECO mode for showing Ma Earth some love, a three-step ambient light sensor for automatically adjusting brightness and DisplayPort / VGA / DVI connectivity. Further specs include an integrated four-port USB 2.0 hub, built-in carry handle, down-firing speakers, a headphone socket, native 1,920 x 1,080 resolution, 270 nits of brightness, a 1,000:1 contrast ratio and a 3-year warranty to keep your mind at ease. Catch it later this month for $379, but good luck scoring that bodacious frog wallpaper.

HP’s just announced its new 27-inch, 16:9 display, the 2709m. This giant puts out a native 1080p picture, and boasts two HDMI inputs, one DVI and one VGA port. With a 30,000:1 contrast ratio, we can expect the display to be nice and vivid, and it’s got two built-in 2-watt speakers, and a reported response time of 5ms. The 2709m is available from HP now for $499.

Sure it’s summertime in New York and not January in Las Vegas, but that didn’t stop LG from rolling out a couple new lines of LCD HDTVs today. The new SL80 and SL90 models don’t bring new high water marks on the spec sheets, but feature LG’s take on the “borderless” design trend that’s the rage these days, built from a single edge to edge piece of glass with a slim bezel and Invisible Speaker design. The top of the line SL90 is due later this year for an unspecified price range in 42- and 47-inch sizes with LED backlighting contributing to its 3,000,000:1 claimed contrast ratio and 1.15 inch depth, plus 120Hz TruMotion processing. The SL80 line has 240Hz processing, but older CCFL backlighting means a 300,000:1 measured contrast ratio and 1.8-inch thick design, but the 42-, 47-, and 55-inch models will be available this August for $1,599, $1,899 and $2,799, respectively.
