Trident 3DImage 9750/9850 3D and Video Accelerator With optional TV Display

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 (TINSATLL) supports a simple five-step installation procedure 
for the display driver setup program, the power management program and the UNinstall program.

To use TINSTALL, 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:\VGA\T9X50\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.SGI 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 TINSTALL 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.

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

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 Trident 3DImage 9750/9850 adapter card or if both the TV-Output connector and the 15-pin VGA
connector of the monitor are connected to the 3DImage 9750/9850 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 'TV' control page and 'Device' control page to select television only features
in display properties once the display driver for Windows 95 has been installed. The 'TV' 
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 available 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 
3DImage 9750/9850'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 3DImage 9750/9850 is capable of video capture through the Feature 
Connector and the Extended Feature Connector.

The ability to capture video data is supported by the 3DImage 9750/9850 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 3DImage 9750/9850 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:\VGA\T9X50\AVI\SETUP  (Where X is the letter of your CD-ROM drive.)
