Description, Features 
and Benefits
The Runco Reflection CL-420 DLP Projector combines a highly efficient optical light 
engine with broad installation and integration options. 
Runco has implemented a host of advancements into the projector’s light engine to take 
full advantage of its widescreen, high-definition SuperOnyx™ Digital Micromirror Device 
(DMD™) chip. The CL-420 features Enhanced GEN 3™ technology to produce deeper 
blacks, greater contrast ratio and brightness, and richly saturated colors. 
Among the CL-420’s features are a sophisticated color-balancing system that results in 
the industry’s best gray scale tracking, and far surpasses the capabilities of CRT 
projectors. Accurate gray scale reproduction is vital to vibrant, true-to-life color 
reproduction, as well as superior black level and white level performance. Runco’s 
acclaimed Vivix™ video processing and scaling assure pristine video imagery, while the 
CL-420’s generous light output capability is powerful enough to handle screens as large 
as 96 inches wide with ease.
The CL-420 features a 16:9 aspect ratio resolution of 1280 x 720, and provides a DVI 
input for pure digital video signal transmission. In addition, the projector’s broad lens shift 
capability, variable throw distance, and electronic horizontal and vertical keystone 
correction allow for flexible placement within virtually any theater environment. Discrete IR 
and/or serial control makes it simple to partner the CL-420 with other audio/video 
components and automated control systems for a truly high-end, home cinema system.

 Native Resolution: 1280 x 720 (16:9 Native Aspect Ratio)
