Appendix A – Internal Jumper Settings

These modifications are only required in very rare circumstances. Composite Sync and Sync-on- Green are only required in RGB mode (never Component/YPbPr mode) and typically only with older, large front projectors. The rule of thumb is if you are seeing a picture on your display, then you have the sync settings correct.

To modify these internal settings, you will need to change a jumper that is only available after opening up your iScan Pro unit. Read through these instructions first and if you feel that you are not comfortable with performing this type of operation, please ask your dealer to make the modification for you. They are generally happy to do so.

Removing the iScan Pro motherboard

1)Find an electrostatic-free environment to work at. Having no carpeting or static-free carpeting is strongly recommended. If you can find an area with some heavy metal parts within easy reaching distance, touching these will allow you to discharge yourself before beginning work.

Rear Panel Screws

2)Turn the iScan Pro unit so that the back of the unit is facing you. Remove the two screws on the back of the unit and set aside in a safe place – you will definitely need these screws later!

3)Discharge yourself by touching some grounded, heavy metal object nearby.

4)Pull the back panel and EMI gasket off of the unit. The iScan Pro printed circuit board is seated in the bottom slot in the chassis housing.

5)Notice the three small metal clips straddling the board below the power input connector, the component video connector and the output connector. You will need to remove these clips and put them aside for replacement later so pay careful attention to how it is mounted on the board. (See picture on next page).

6)Pull the board all of the way out of the housing.

Progressive Scan Display Interface specifications

DVDO Progressive Scan Display Interface (PDI) is an advanced technology designed to enhance video quality and user experience in display systems. It serves as a bridge between source devices, like DVD players or gaming consoles, and output displays such as televisions and projectors. The main purpose of the PDI is to provide a better visual experience by minimizing motion artifacts, enhancing color accuracy, and improving overall image clarity.

One of the key features of DVDO PDI technology is its progressive scan capability. Unlike traditional interlaced scanning methods where alternate lines of an image are displayed in each frame, progressive scanning delivers the entire image at once. This results in smoother motion and sharper images, especially beneficial for fast-paced content like sports or action movies.

Another important characteristic of DVDO PDI is its upscaling ability. The interface can take lower resolution video sources and convert them into higher quality outputs, ensuring that older video content can still look impressive on today’s high-definition displays. This upscaling feature is critical for users who still want to enjoy classic films or legacy video games without compromising on picture quality.

The technology also incorporates sophisticated deinterlacing algorithms that intelligently analyze video signals. These algorithms help in reducing visual artifacts such as combing and blurring, commonly found in interlaced video formats. This enhancement is particularly useful for mixed video sources, allowing seamless switching between different content types without noticeable degradation in quality.

DVDO PDI is also designed with various connectivity options to ensure compatibility with a wide range of devices. High-definition multimedia interface (HDMI) compatibility allows for easy integration with modern displays, while additional outputs can cater to older systems, making it a versatile choice for multimedia setups.

Moreover, the user-friendly features of DVDO PDI include adjustable settings for color calibration, contrast enhancement, and image scaling, allowing users to customize their viewing experience. This adaptability makes it suitable for both home theater enthusiasts and casual viewers alike.

In conclusion, the DVDO Progressive Scan Display Interface stands out with its combination of progressive scanning, upscaling, intelligent deinterlacing, and extensive connectivity options. These characteristics work together to deliver an enhanced viewing experience, ensuring that users enjoy superior video quality regardless of the source material. As technology continues to evolve, DVDO remains at the forefront of display innovations, offering solutions that cater to the diverse needs of consumers.
