Overall Functional Description
The VX-4000ci system consists of the DHD Controller and the VX-4000ci Projector. This system is unique in the way it is controlled; the control center for this system is located within the DHD Controller. The DHD Controller tells the Projector to turn on or off, controls its brightness, contrast, color tempera- ture and more. All of this is accomplished by Runco's unique ComLink, which is the transfer of informa- tion between the DHD Controller and the Projector via their ComLink ports on a CAT5 cable (or similar) with RJ-11 connectors. Therefore, only the DHD Controller's remote control is necessary to control all aspects of this system.
Besides being the system's control center, the DHD Controller is also a high-quality scaler, which outputs all signals in the native resolution of the VX-4000ci Projector. The Composite, S-Video and Component (non-progressive) signals are sent through the DHD Controller's 10-bit decoder, de-inter- laced, then scaled to the native resolution of the Projector. In the case of HDTV or progressive DVD sig- nals, these are input to the RGB/Component port.
In the next chapter, the menu system will be described in detail. There are many adjustments available to perfect the VX-4000ci's image, including typical 'front-panel controls' as well as color temperature and other image-quality controls.
