Tualatin, Ore., October 27, 1999 — ViewSonic® Corporation, the top-selling monitor manufacturer in the United States, will be shipping in the fourth quarter of 1999 two new flat panel LCD monitors powered by Pixelworks™ ImageProcessors. The new ViewSonic flat panel monitors are the first flat panels to incorporate digital, analog and video inputs into the same display. ViewSonic chose Pixelworks' innovative single-chip ImageProcessors as the best display controllers capable of handling the complex task of delivering outstanding images on the screen regardless of the source.

The ViewSonic VP181 and VP151 ViewPanels®, an 18-inch SXGA-resolution and 15-inch XGA-resolution LCD monitors respectively, provide five inputs including two digital inputs, two analog inputs and one video input. The VP181 and VP151 accept DFP and DVI digital interfaces as well as worldwide video standards including NTSC, PAL and SECAM. The maximum input resolutions are UXGA for the VP181 and SXGA for the VP151.

The single-chip Pixelworks ImageProcessors are capable of handling the current analog and video standards and state-of-the-art digital standards including VESA Digital Flat Panel and the Intel-led Digital Display Working Group's Digital Visual Interface (DVI). The Pixelworks ImageProcessors offer wide ranging compatibility with nearly every personal computer and video source including broadcast, satellite, cable and digital television, VCRs and DVD players.

"ViewSonic is committed to making our ViewPanels as versatile as possible by giving our customers the ability to connect with virtually every computer and video source. Pixelworks ImageProcessors have made this a reality by delivering an innovative and cost-effective chip capable of handling the current and cutting-edge digital visual standards," said Marc McConnaughey, Vice President of Technology and Sourcing for ViewSonic.

"ViewSonic has a solid track record in developing innovative, award-winning display products. We are pleased that our ImageProcessors are enabling industry leaders like ViewSonic to quickly develop and introduce the next generation of high-performance advanced display products," said Allen Alley, CEO and Chairman of Pixelworks.

The Pixelworks ImageProcessors automatically interpret and adjust incoming computer graphics and video signals to ensure that the highest-quality images are displayed. Pixelworks' state-of-the-art ImageProcessors enable ViewSonic to offer advanced image enhancement features in its flat panel monitors. The unique Pixelworks' automatic image optimization gives users true "plug and play" functionality.

Both the VP181 and VP151 employ Pixelworks' exclusive picture-in-picture (PIP) feature. For the first time customers can simultaneously have a video window on the screen while showing an analog computer source.

Another feature powered by the Pixelworks ImageProcessor is ViewSonic's ViewMatch® color control system. Using the ImageProcessor's gamma control, a user can adjust the shade and tone of colors on the screen. For example, a graphic designer could set her display to show colors exactly as they appear on a printed page.
