But because some monitors “overscan” their screens, some desirable parts of your images could be cropped off the screen. If this happens, press this button to shrink the images, both horizontally and vertically, approximately 10% in size. (The button’s green LED will light.) Press the button again to restore the images to their original sizes; the LED will go dark. 9 PROVIDEO CONVERTER AND VIDEO CONVERTER II ANTI-FLICKER BUTTON: When this button has not been pressed, the Converter sends images using fully interlaced composite, S-Video, and RGBS video signals. However, thin horizontal lines in the images might appear to “flicker” on and off at a very fast rate. If this happens, you can use this button to activate one of two levels of flicker reduction. When you press this button once, its green light will flash once and stay lit, indicating that “level 1” of flicker reduction is active. Level 1 may still show some flicker but will preserve a greater amount of detail than level 2. Use level 1 unless you still find the flicker annoying. When you press this button a second time, its green light will flash twice and stay lit, indicating that “level 2” of flicker reduction is active. Level 2 will completely eliminate the flicker but will also reduce the detail in the image. Press the button a third time to turn off the anti-flicker filter; the LED will go dark. FREEZE BUTTON: If you want to freeze a frame of an image sequence on the screen without stopping your computer application, press this button: The image on the Composite, S-Video, and RGBS outputs will be frozen and the button’s green LED will light. When you press this button again, the Converter will resume outputting images received from your computer and the LED will go dark. IMAGE-POSITIONING ARROWS: TV monitors and video projectors may not always display the image in the center of the screen even when it is underscanned. The Converter has four buttons that allow you to move the displayed image up, down, left, and right to properly position it in the center of the screen. Each time you press one of these arrows, the image will be moved one increment in the corresponding direction. If you press and hold an arrow down, the Converter will move the image continuously, slowly at first, then quickly. MAGNIFY BUTTON (ProVideo Converter only): Pushing this button will magnify the image from your computer by approximately 160%. When you first press the button, the button’s green LED will light and the upper left- hand corner of the computer image will fill the full screen of the ProVideo Converter’s output. 10 CHAPTER 4: Operation By using the four positioning arrows, you can show any magnified portion of the original computer image. You can also move the display by pressing the HOME (UNDERSCAN) button: Each time you press it, the display will move to a different portion of the image: First time: Center Second time: Upper left-hand corner Third time: Lower left-hand corner Fourth time: Lower right-hand corner Fifth time: Upper right-hand corner Sixth time, etc.: (Cycle repeats) To restore the image to its original size, either press the MAGNIFY button again or press the TEST button. The MAGNIFY LED will go dark. 4.3 Other Features 4.3.1 THE BLUE SCREEN From time to time the Converter might output a blue screen, either momentarily or continuously. The ProVideo Converter and Video Converter II automatically produce this blue screen under any one of the following conditions: • Output flashes blue briefly: Your computer temporarily changes resolutions while running a program. • Output continuously blue: There is no input signal from the computer. • Output continuously blue: There is a signal from the computer, but its resolution and/or refresh rate are not supported by the Converter. If you think you shouldn’t be getting a blue screen, make sure one of the above conditions is not occurring. 11 PROVIDEO CONVERTER AND VIDEO CONVERTER II 4.3.2 COMPUTER-DISPLAY RESOLUTION SUPPORT The ProVideo Converter and Video Converter II do their best to determine the pixel resolution (for example, 640 x 480) and the vertical refresh rate (for example, 72 Hz) of every image that comes from your computer. While there are published standards for most of the display modes, some manufacturers of older cards may have chosen to vary slightly from these standards. If you encounter a display mode that matches one of the Resolutions and Refresh Rates listed in Chapter 1, but the Converter does not respond to it, notify your supplier of the problem; tell them the make and model of the computer and video-display card, as well as the display resolution and vertical refresh rate you’re having a problem with. 4.3.3 THE COMPUTER-INPUT CABLE The special cable that connects your computer to your Converter, included with your ProVideo Converter or Video Converter II package, is designed to be compatible with both VGA and Macintosh computers. It is specially wired, and DB15-to-DB15HD adapters cannot...
