Monitor maker Viewsonic is to enter the all-in-one PC market with the launch of the VPC 100. Available initially in the US, the Viewsonic VPC100 will have an 18.5in LCD screen and run off a 1.6GHz Intel Atom processor. A Windows XP machine, it will have a 160GB hard disk drive and a DVD drive that is mounted vertically into the back of the machine.

Viewsonic UK and EMEA product manager John Barnes told PC Advisor that the VPC100 will come with 802.1b and g wireless connectivity and Bluetooth and will have a three-in-one photo card reader. The Viewsonic VPC100 will launch this quarter in the US for $499 inc VAT.

A larger screen model, which has yet to be formally named but which has a 21.5in flatscreen LCD display, is set to launch in Q2 and will go onsale in the UK and Russia. This all-in-one PC is set to improve upon the basic 1GB RAM provision of the VPC100 and will be a partially touchscreen device offer access to media control and playback buttons via a vertical touch-sensitive menu on the righthand side. It is also likely to run Windows Vista rather than Windows XP.

Barnes acknowledged the likely shortcomings of the entrylevel VPC100 model and said the larger 18.5in all-in-one PC would almost certainly have more onboard RAM, a desktop processor and an HDMI connection to hook it up to a high-definition Blu-ray player.

Pricing for the 18.5in Viewsonic all-in-one PC has yet to be determined, but it is expected to go onsale in Q2 of this year.

Viewsonic is primarily known for its business and consumer PC monitors and for its TVs but is looking to diversify by extending its screen-based product range with 3D gaming monitors, home cinema projectors, digital photo frames and all-in-one devices such as the VPC100 all-in-one PC.

Also at CES, Viewsonic has been showing off its 3D projector and its stereoscopic 3D gaming monitors which work with the latest nVidia 3D graphics card. A 22in VX2265 flatpanel monitor was used to demonstrate both 3D video footage and 3D games. In common with Samsung, Viewsonic is punting 120Hz displays and the ability to show smooth 3D games playback when used in conjunction with nVidia's 3D polarised glasses.

Unlike LG, Philips and Samsung, Viewsonic will stick to producing stereoscopic 3D (which requires the user to don special 3D glasses) and won't develop lenticular screens. The latter can be viewed without the need for viewing apparatus, but requires the viewer to stand dead centre in front of the screen image and to view the screen at a certain distance in order to appreciate the effect.
