Still images recorded using the Exchangable Image File Format (EXIF) for digital still cameras and Design Rules for Camera File Systems (DCF). 2. Standard digital images with a maximum size of 5-megapixels (2560x1920). 3. File name maximum of 50 characters ending with a .jpg extension. For MP3 or WMA7 Audio files: 1. Files recorded with sampling rates of 32 KHz, 44.1 KHz or 48KHz. 2. Files recorded with fixed bit rates. 3. File names with .jpg or .wma extensions. NOTES: Images opened and resaved on a computer may not playback or may not be able to display a picture in the thumbnail list. This is because the computer may change the file to an incompatible format. For audio playback, the audio output from the TV to the A/V receiver is analog. Digital audio output is not available. PerfectColor™ With conventional tint controls providing only a tradeoff between red and green, PerfectColor was developed to provide precise control over the 6 individual primary and secondary colors. Introduced in the V20 Chassis, PerfectColor was initially limited to 480i composite video sources only. For the V22 and V23 chassis, PerfectColor can be setup individually for each and every Input and is compatible with all video source formats. (480i, 480p, 1080i) A colorbar chart with slider controls is provided in the menu for easy reference. See Figure 8. PerfectColor can also provide automatic color correction. Compared to conventional “Auto Color” systems, it can better sense and correct for color differences when changing channels. It is specifically designed for the customer that watches a wide range of channels where no one setting can be used. NOTE: Improperly set, PerfectColor can exhibit a wide variety of color symptoms. These symptoms will not affect the on-screen menus or a black and white picture. In such instances, be sure to check the PerfectColor settings prior to troubleshooting.

MonitorLink provides a proprietary connection for Mitsubishi's HD-5000, Monitor/Receiver, allowing Mitsubishi's upgradeability promise to be fulfilled using a digital, rather than analog, interface. While MonitorLink is a proprietary connection, it uses industry standard technologies that may provide even more versatility. • RS-232C - Provides device communication and control. • Audio - Standard analog stereo connections. • DVI - (Digital Visual Interface) Provides a digital video connection. RS-232C… The RS-232C connection interfaces communications and control between the receiver/ controller and display. Commands such as Power On, Input, Mute, etc., make the system operate as one via the customer's remote control. Audio… Analog Left and Right Audio connectors are provided for the set's internal audio/speaker system. The V23 chassis has digital audio outputs and IEEE1394 for more advanced connections with an external A/V receiver. DVI… Technicians experienced with computer monitors may already be familiar with DVI and its features. However, because it is new to home theater, it will be covered here further. Figure 9: MonitorLink Input Digital Visual Interface (DVI) DVI was originally designed by the Digital Display Working Group (DDWG) to provide a universally accepted digital connection between a PC and a display device. At first glance, another digital interface would seem unnecessary with the presence of IEEE1394, Firewire. However, differences between IEEE1394 and DVI make them each suitable for different applications. A comparison of the two interfaces, as applied to home theater, is provided in Table 4. Simply stated, 1394's bi-directional, compressed data, and AV control capabilities make it suited for recording and networking between various devices. DVI's high speed, full bandwidth capabilities make it most suitable to connect a display device.
