TAIPEI -- Asus has further added to its now extensive lineup of Zen-branded products with a new Zen all-in-one PC range.

Asus has a long history of all-in-one products -- monitors with PCs built-in -- but this is the first to bear the Taiwan tech giant's premium Zen brand.

The Zen AiO series will initially have two models, the top-of-the-line 23.8-inch Zen AiO Z240IC and the 21.5-inch Zen AiO Z220IC. Both have a slim unibody shell made from a single block of anodised aluminium and an edge-to-edge glass cover over the display.

The specifications will differ from model to model, but at the top specs, you're looking at a quad-core Core i7 Intel processor with 32GB of RAM, 512GB of PCIe Gen 3 x4 SSD storage and an Nvidia GeForce GTX 960M graphics card.

The Zen AiO will also feature the latest USB 3.1 Generation 2 ports -- running twice as fast as USB 3.0, according to Asus, although not with the cool new Type-C reversible connector. On the home entertainment front, the AiO has six speakers, with three on each side of the unit in a combined 8-watt stereo channel.

The 23.8-inch Zen AiO will also have Intel's RealSense 3D camera built in. The RealSense camera can be used to add motion-sensing capabilities as well as functioning as a 3D scanner. Additionally, Asus has added some microphone enhancements designed to clear ambient noise and optimise speech recognition, all in aid of improving the experience of Cortana, Microsoft's voice-activated digital assistant.

No pricing or availability has been announced for the Zen AiO range at present.

Asus also revealed the ProArt PA329Q monitor, a 32-inch Ultra HD (3,840x2,160-pixel) monitor aimed at the professional market. The monitor has a 16:9 aspect ratio IPS display with a wide 178-degree viewing angle to eliminate colour shifting. Again, no pricing and availability details at the moment.
