Overview

This document provides instructions on the installation of the software drivers supplied with the graphics accelerator board.  These software drivers offer performance and quality improvements over the standard graphics software drivers supplied with the computer system, and extend the graphics capability for selected applications by offering options such as increased screen size, color depth and monitor refresh rates, as well as improving overall graphic performance.

1. Microsoft Windows 3.1

1.1	INSTALLATION 
The graphic installation program (SETUP) supports a simple six-step installation procedure for the display driver setup program, the power management program and the UNinstall program.

To use SETUP, follow the 5 steps below:
1.	ENSURE that MS Windows 3.1x is up and running  properly, using the 	standard VGA driver.
2.	SELECT the MAIN group in Program Manager.
3.	CLICK on FILE or press ALT + F4
4.	CLICK on RUN or PRESS R to select command line.
5.	TYPE in X:\WIN_31\DISPLAY\TINSTALL  (Where X is the letter of your CD-ROM drive.) 

Choose Express installation for quick and decision-free installation. Display drivers will be copied into the TRIDENT.HGI directory and Utility files will be copied into the TRIDENT.UTL directory. Once all files are copied, a program group called DISPLAY DRIVER AND UTILITIES will be created.

When all necessary files are copied and a group name is selected, the SETUP program will create three icons:
a.	Screen Control (Used to configure display drivers).
b.	DPMS (Used for power management configurations).
c.	UNinstall (Used to delete the installed TRIDENT drivers).

1.2	SCREEN CONTROL
The Screen Control panel contains controls for setting screen resolution, color depth, font size, refresh rates. 
Color depths of 16, 256, 64K, or 16.7M colors can be selected by clicking next to the desired option. 
Screen resolutions of 640x480, 800x600, 1024x768, 1280x1024 or 1600x1200 can be selected by clicking next to the available options. 
Available refresh rates are dependent on the selected color depth and resolution. 

Configuring the Display Driver
	Select the color depth first.
	Select the resolution.
	Select the font size (if available as an option).
	Select the refresh rate.
	Click on OK. If the current driver does not support the selected 	configuration, Windows will have to be restarted.

1.3 Video for Windows 1.1 Installation
You may perform following steps to install Video for Windows 1.1.

	1. TYPE in X:\Win_31\VFW11E\SETUP  (Where X is the letter of your CD-ROM 	drive.)

6.	Restart Windows 95 to complete installation.

3. TV Display  in Windows 3.x or Windows 95

Make sure that jumper JP14 is not installed (open position) so that your TV will be the default display device if a S-Video TV-Output connector or a composite TV-Output connector is connected to your TV. Your color monitor will be the default display device if only the 15-pin VGA connector of the monitor is connected to the VGA output connector of the ProVidia9685 adapter card or if both the TV-Output connector and the 15-pin VGA connector of the monitor are connected to the ProVidia9685 adapter card.

 In Windows 3.x, use the Display Control program in Display Driver and Utility Program Group to access TV display features and to switch from color monitor to TV as the default display device and vice versa.  The Display Control program allows the user to select Underscan or Overscan, to select interlaced or non-interlaced, to select degree of flicker reduction and to adjust screen shift both horizontally and vertically. 

In Windows 95, use 'Television' control page and 'Display Device' control page  to select television only features in display properties once the display driver for Windows 95 has been installed..  The 'Television' control page allows the user to select 'Underscan' or 'Overscan', to select 'Interlaced' or 'Non-interlaced',  to adjust the 'Screen Shift' of the television display horizontally and to select the degree of flicker reduction under Advance control button. The 'Display Device' control page allows the user to switch from color monitor to TV as the default display device and vice versa.

In DOS, a TSR program "TVDISP" is availabe in the directory of "X:\DOSUTL\TVGAUTIL\UTILITY"	 (where X is the letter of your CD-ROM drive). This program allows the user to select 'Underscan' or 'Overscan', to select 'Interlaced' or 'Non-interlaced', to switch from color monitor to TV as the default display device and vice versa, to adjust the 'Screen Shift' of the television display both horizontally and vertically,  and to contract or expand the size of screen both horizontally and vertically.  More information about the TVDISP program is available in the REAME.TXT file of this directory.

Conventional broadcast TV or VCR content provides an "Overscanned" viewing area in order to ensure that the entire visible screen is used. The result is that portions of the image along the border are beyond the physical screen. The actual visual area lost is dependent on the individual TV model.  On the other hand, a PC system display content should be within the boundaries of the physically viewable screen. This is called underscan. When the TV is used as the display device in a PC, display hardware needs to control the image generation circuitry to drive the underscan timing to the TV.

Besides generating interlaced timing, hardware may have the option to drive non-interlaced timing to the TV. A non-interlaced display will remove much of the flicker effect but reduce the detail of the image.

The interlaced timing of a TV causes a flickering effect on the screen. Depending on the TV standard and tube phosphor material, the severity of flicker differs from one brand and model of TV to another. Since TV content is almost always full-motion video or animation, flicker is not as noticeable as it is when the screen content is stationary. Flickers are caused by TV low frame rate as well as the interlacing of adjacent scans. This flicker is most obvious when a particular scan contrasts highly with the scans directly above and below, such as a black horizontal line on a white background. This type of flicker can be greatly reduced by ProVidia9685's built-in flicker reduction filter.

4. Video Capture Software Installation (Optional) 

Video Capture is  the process of accepting video data from an outside source, such as TV tuner, VCR, Laser Disc Player or a Camcorder and writing it to the frame buffer, from where it can then be displayed or stored.  The ProVidia9685 is capable of video capture through the Feature Connector and the  Extended Feature Connector.

The ability to capture video data is supported by the ProVidia9685 chip set; however, additional adapter or hardware may be required to activate this feature. Please check with your dealer or card manufacturer to find out if this optional feature is available on your video adapter card.

While Microsoft's Video for Windows 1.1e Video Playback program is installed automatically when Display Driver for Windows 3.1 is installed,  Microsoft's Video for Windows 1.1e Video Playback comes pre-installed on  Windows 95.

To installed  Video Capture programs which have to be purchased separately in Windows 95, please follow the installation instructions included with each Video Capture program.  Please look for application programs from companies such as Adobe, in:Sync, Asymetrix, etc which are capable of video capture. 

The ProVidia9685 Video Capture drivers that support application programs which are capable of video capture  can be installed by following these steps below:

1. 	Insert the Trident Installation CD-ROM into your CD-ROM drive.
2. 	TYPE in X:\AVI\AVISETUP  (Where X is the letter of your CD-ROM drive.)
3. 	The Trident AVI Drivers Setup screen will appear.  
	PRESS "continue" to complete the installation process of Trident AVI Drivers. 

5. Microsoft Windows NT 

5.1 	NT 3.5 INSTALLATION 

1.    RUN the Microsoft Windows NT display Setup program      located in the Control Panel of the Main group.
