As ThinkPad enthusiasts at ThinkPad.com report, Chinese PC manufacturer Lenovo has announced three new Full-HD LCDs. The screens, in sizes of between 21.5 and 23.6 inches, all have a native resolution of 1,920 x 1,080 pixels. The 23-inch model also supports multiple finger control via Multitouch.
With a screen diagonal of 21.5 inches, the smallest of the three newcomers, the Lenovo L2261, offers a relatively high pixel density of 103dpi. As a display, a TN panel with white LED backlight has been used, with a maximum brightness of 250 cd/m². This, typical, or static contrast ratio is 1,000:1 and the response time is five milliseconds.
The viewing angle stability indicated applies for a resting contrast of 10:1, with typical TN values of 170 degrees (horizontal) and 160 degrees (vertical). The number of monitor inputs is also not overwhelming: one VGA and one DVI connection, no HDMI. The user will also look for ergonomic functions in vain, since the 16:9 monitor is not height adjustable or pivotable, but can only be tilted and turned.

More elegant and a size class higher is the Lenovo L2361p. 1,920 x 1,080 pixels are provided on a screen diagonal of exactly 23 inches. Otherwise, there are not many differences. Like the L2261, the L2361p has a TN panel with White LED backlight, a maximum brightness of 250 cd/m² at a static contrast ratio of 1,000:1 and a response time of five milliseconds. The aspect ratio and viewing angle are also identical to those of the smaller model.
Instead of DVI, the 23-inch monitor has a HDMI input as well as VGA, plus a USB hub which allows for three USB connections via an uplink. The connection to the webcam integrated into the monitor together with a microphone is achieved via USB. However because of its special design, which is reminiscent of an all-in-one PC for the living room, the screen can only be tilted and does not have any additional ergonomic functions.

Lnovo’s third new arrival, the L2461x , is more amply equipped in some respects. Its TN display has a diagonal of 23.06 inches, but does not differ to the smaller models except in terms of the maximum brightness (300 cd/m²) and the higher resolution webcam. Four instead of three end devices can be connected to its USB hub.
The most striking feature of this model is its Multitouch ability. According to the datasheet, it has 120-Hertz MEMC technology (Motion Estimation / Motion Compensation), which evaluates and balances movements. Seemingly, this is a capacitative touch monitor. Not much is yet known about prices and availability; it is only known that the L2461x will be sold for 549 to 580 Dollars by American retailers.
