28-inch Ultra HD screen houses noise cancelling microphone, webcam
Lenovo has revealed even more monitors at CES, including another 4K-resolution model to accompany the ThinkVision displays unveiled yesterday. The 28-inch LI2821 offers another Ultra HD option to consider, while the 21.5-inch LI2223s and the 23-inch LI2323s displays are IPS screens with a 1080p resolution and a borderless design.
The 4K-capable LI2821 has a 5ms response time, a dynamic contrast of 10 million:1, and the ability to split the screen to simultaneously show up to four sources. DisplayPort, HDMI, VGA, and MHL connectivity, is touted, along with a built-in 1080p webcam with privacy cover, a dual array noise cancellation mic, volume and mute buttons, and JBL speakers meant to make VOIP or video conferencing simpler.
The 21.5-inch and 23-inch displays do not come supplied with the webcam and speakers of the Ultra HD monitor, but still offer a matte 1920x1080-resolution display with a response time of 7ms and an identical dynamic contrast. The LI2223s and the LI2323s use VGA and DVI inputs, with the 23-inch display stretching to include HDMI as well, with both including a tool-free option to remove the aluminum stand for VESA wall mounting.
The 28-inch LI2821, 23-inch LI2323s and 21.5-inch LI2223s will be shipping in June, priced at $799, $220, and $180 respectively.
