Kramer Introduces the 840 DVI Pattern Generator Which Includes Unique Movement Patterns

07 February 2005

Hampton, New Jersey – February 7, 2005 - Kramer Electronics, Ltd., a worldwide supplier of audio, video and computer graphics signal distribution, switching and processing equipment for the broadcast, production, security, education, home theater and ProAV presentation markets, is pleased to announce the newest addition to its product line -- the 840 DVI pattern generator. The 840 is the ultimate DVI display evaluation tool and is an essential product for all engineering and sales personnel in the business of selling and calibrating DVI capable displays and accessories.

The 840 comes with 32 built-in patterns including some unique patterns containing movement to allow testing of display refresh rate performance. All 32 patterns in the 840 have been carefully chosen to ensure that the 840 can effectively evaluate every important aspect of a DVI display or accessory. These include, but are not limited to, the refresh rate performance, testing of overall linearity, the linearity of each pixel component and identifying missing pixel components of fixed resolution display devices such as LCD and plasma monitors and LCD and DLP projectors. The 840 also has patterns that are designed to aid in the testing of DVI accessories such as scalers, distribution amplifiers and switchers, as well as DVI cables.

“The 840 is a product that engineering and sales professionals in the display business should not leave the office without. They should grab their keys, their cell phone and the 840,” states Chris Kopin Vice President of Product Development for Kramer Electronics. “With its compact size, a comprehensive offering of 32 patterns including some very unique patterns that include motion and its support for multiple output resolutions including computer graphics video, widescreen and HDTV standards, the 840 is the ideal product for evaluating, calibrating and troubleshooting today’s fixed resolution DVI displays, cables and accessories.”

The 840 has 12 output resolutions, four of which conform to VESA standards including SVGA (800x600), XGA (1024x768), SXGA (1280x1024) and UXGA (1600x1200). In addition to those computer graphics video output resolutions, the 840 also offers a 1400x1050 (4:3) output resolution along with seven widescreen and HDTV resolutions including 480P (720x480), 852x480, 960x540, 720P (1280x720), 1366x768, 1080i (1920x540) and 1080p (1920x1080). All these signals are output at @60Hz.

The 840 supports both 4:3 and 16:9 aspect ratios and has circle patterns to allow the evaluation of proper aspect ratio reproduction. For convenience of use, an on board EEPROM saves the last setting used. The 840 has one DVI-D output, 7 control buttons, and a 7-segment display indicating the pattern number being output. It is housed in a compact Kramer DigiTools™ size cabinet and powered by a standard 12VDC power supply. It can also be used with the Kramer VA-100 portable/rechargeable power supply.
