DESCRIPTION
USER PRODUCTIVITY

ERGONOMIC DESIGN AND SCREEN FLICKER: Today's widespread move to applications based on graphical user interfaces and higher screen resolutions places greater demands on the ergonomic design of visual subsystems. High resolution graphics modes and white screen backgrounds can promote more noticeable screen flicker, a condition that may affect user productivity. Flicker, however, can be reduced by increasing the screen refresh rate--the number of times per second that the screen image is redrawn. Flicker can also be reduced by non-interlaced scanning--or drawing the whole screen image in one pass. Reducing screen flicker can improve user productivity.

The IBM PS/2 XGA-2 Display Adapter/A supports higher refresh rates up to 75Hz for use with appropriate monitors. Also, the XGA-2 Display Adapter/A now supports non-interlaced scanning in 1024 x 768 mode. Higher refresh rates and non-interlaced scanning combine to enhance ergonomic benefits to the customer in the form of enhanced usability and potential productivity gains.

PERFORMANCE: The IBM PS/2 XGA Display Adapter/A set a new standard for high performance video subsystems, providing the high-performance graphics and high screen content demanded by graphical user interfaces in Operating System/2 (R) (OS/2 (R)) Presentation Manager (R), Microsoft Windows, AIX (R) and other environments. Optimized for windowing and high resolution performance, XGA features: The XGA-2 Display Adapter/A further enhances the performance benefits of several of the key features. Performance of the XGA-2 Display Adapter/A advanced function modes is over twice the performance at the application level, due to faster VRAMs, memory controller redesign, improved busmastering, more efficient coprocessor polling, and significant tuning of the device drivers.
 * Faster VGA
 * Dual-port video memory (VRAM)
 * Bus mastering
 * Drawing acceleration (coprocessor)
 * Hardware cursor (sprite)
 * Application device drivers.

Also, XGA-2 Display Adapter/A provides full coprocessor support for direct color mode, allowing customers the benefit of 640 x 480 resolution with 65,536 colors at a performance level comparable to XGA 640 x 480 with 256 colors.

CLARITY AND READABILITY: The IBM PS/2 XGA-2 Display Adapter/A provides improved 132 column text support. While the adapter still supports the 8-pixel character resolutions of XGA Display Adapter/A, it also provide a 9-pixel character resolutions of 1188 x 200, 1188 x 350, and 1188 x 400. This will further improve the clarity and readability of the text.

GROWTH ENABLEMENT

COLOR ENHANCEMENTS: The announcement of XGA Display Adapter/A enabled customers to take advantage of an increasing number of applications with graphical user interfaces, higher screen content, and more colors. XGA Display Adapter/A was upgradeable to 640 x 480 with 65,536 colors and 1024 x 768 with 256 colors by means of an extra-charge memory feature, the PS/2 Video Memory Expansion Option.

Displaying up to 65,536 colors at once (16-bit color mode) can yield a high-color, lifelike display of scanned or captured color images. The XGA-2 Display Adapter/A provides the same capabilities with 1MB of VRAM on the standard adapter for no additional charge. And 16-bit color mode is now supported by OS/2 and Windows device drivers.

The XGA-2 Display Adapter/A also features 8-bit digital-to-analog converters (DACs), versus the 6-bit DACs used by XGA Display Adapter. With 8-bit DACs, the XGA-2 Display Adapter/A now supports a palette of 16.7 million possible color combinations of which 256 can be displayed at any one time. (the XGA Display Adapter allows 256 of a possible 262,144 colors.) Similarly, the XGA-2 Display Adapter/A provides 256 possible shades of grey, compared with XGA Display Adapter's 64 shades.

ERGONOMIC AND ENVIRONMENTAL REQUIREMENTS -- STANDARDS: With the XGA-2 Display Adapter/A, customers have a growth path to current and new applications that use enhanced-color modes. The XGA-2 Display Adapter/A and the new 95XX family of monitors are designed to meet stringent ergonomic and environmental requirements of emerging international standards, such as the International Standards Organization (ISO). The new adapter card and monitors provide customers the means of meeting governmental requirements where applicable, as well as deriving the benefits of front-of-screen usability features such as... The XGA-2 Display Adapter/A can also be used with non-IBM monitors conforming with Video Electronics Standards Association (VESA) specifications for... To enable customers to take advantage of the XGA-2 enhanced features, new versions of video device drivers are provided, including IBM OS/2 1.3 and 2.0, IBM AIX PS/2 1.3, IBM DOS, Microsoft (3) Windows (4) 3.0 and 3.1, and AutoCAD (5) 10 and 11.

INVESTMENT PROTECTION

As an extension to the XGA architecture, the XGA-2 Display Adapter/A provides all the function and support provided by the existing XGA Display Adapter/A for monitor products. In addition, the XGA-2 Display Adapter/A supports other industry resolutions, such as, the VESA standard of 800 x 600 with 64K colors. Customers, therefore, are assured of continued use of existing 85XX monitors and applications as well as benefit from the enhanced features of the XGA-2 Display Adapter/A and new 95XX monitors. Refer to the Specified Operating Environment section for complete information on monitor support.

All applications that were supported on the XGA Display Adapter/A run unchanged on XGA-2 Display Adapter/A (assuming the applications followed the XGA technical Reference Guidelines and the customer is using an 85XX monitor). This includes applications written to the application program interface (API) of DOS, OS/2 PM, Microsoft Windows, and AutoCAD. A variety of XGA-compatible applications provided by vendors also support the XGA-2 Display Adapter/A. Refer to the Specified Operating Environment section for more information on application support.

Significant performance improvements have been made to the device drivers provided for the XGA-2 Display Adapter/A. These drivers have been designed to maintain downward compatibility with the XGA Display Adapter/A. This will allow existing customers to enjoy some of the performance improvements provided for the XGA-2 Display Adapter/A.

SYSTEMS MANAGEMENT

The XGA-2 Display Adapter/A has been designed to reduced the complexity and therefore cost of systems management. The XGA-2 Display Adapter/A has a programmable PEL clock generator, and as such it does not have any fixed resolutions or modes. The resolutions available are depend on the display attached rather than a function of the adapter card. The XGA-2 Display Adapter/A is also easier to configure. The EPROM is now relocatable and the 1MB aperture can be disabled. In addition, the device drivers are modified to support Display Mode Query and Set (DMQS), a comprehensive new method for identifying monitors and display adapter characteristics.

The combinations of these features provide a new flexibility for system configuration and inventory management of displays and graphics adapter cards.

PRODUCT POSITIONING

The software supplied with the XGA-2 Display Adapter/A automatically exploits IBM 85XX and 95XX monitors at the best resolution and refresh rate possible for the monitor attached.

Supported resolutions detailed above that are not available on IBM displays, are available with some non-IBM (OEM) displays. These displays range in capability from low cost/low function to high cost/high function. Most of these displays respond as an IBM 8514 display when queried by the software supplied with the XGA-2 subsystem. As a result, IBM 8514 resolutions and refresh rates are used as default.

The software supplied with the IBM XGA-2 Display Adapter/A, allows the user to override the default screen resolution. Overriding with a resolution which does not meet (or exceeds) the capability of the attached display, can yield unpredictable results.

WARNING: Some multi frequency displays may appear to function correctly, however damage may occur over time.
 * The user must only select resolutions which are suitable for the display attached to the XGA-2 Display Adapter/A.
 * The use of the resolution override should be avoided if the display attached to the XGA-2 Display Adapter/A is to be changed frequently with displays of varying characteristics.

The IBM PS/2 XGA-2 Display Adapter/A along with certain IBM displays, computers and some software has been certified to meet the International Standards Organization (ISO) standard 9241/3. IBM cannot guarantee that all OEM and 63XX displays attached to the XGA-2 Display Adapter/A will provide acceptable front of screen characteristics or meet the ISO 9241/3 standard.

COMPATIBILITY:

Hardware Compatibility - While providing additional capabilities, the XGA-2 Display Adapter/A is fully compatible with the XGA Display Adapter/A. (Refer to the PS/2 Hardware Interface Technical Reference - Video Subsystem, S42G-2193-00, for additional information.)

In VGA mode, XGA-2 Display Adapter/A is fully compatible with XGA Display Adapter/A. No application modifications are required.

In 132 column text mode, XGA-2 Display Adapter/A supports the same 8-pixel characters and resolutions (1056x200, 1056x350, 1056x400) as XGA. In addition, XGA-2 Display Adapter/A provides 9-pixel characters with resolutions of 1188x200, 1188x350, and 1188x400. 132 column text mode can be displayed with either ISO or non-ISO refresh rates, but should be invoked only when the attached monitor can accept the appropriate video rates. Refer to the Display Units Supported section for details on video rates.

IBM recommends that applications developers use the BIOS mode 14h call to invoke 132 column text mode to ensure future compatibility. Applications written to XGA hardware for 132 column support (1056 PELS) will also get 1056 PELS with XGA-2 hardware. Applications written to BIOS mode 14h will get 1056 PEL on XGA hardware and 1188 PELS on XGA-2 hardware.

In extended graphics mode, XGA-2 Display Adapter/A supports all the same functions as the XGA Display Adapter/A and provides the following additional capabilities:
 * Enhanced coprocessor support for 16-bit direct color mode.
 * Enhanced DACs for expanded color selection.

Application modifications may be required depending on the type of monitor attached (refer to the Software Compatibility section).

Software Compatibility

 * full screen windows support.

Un-supported applications
 * 8514/A OS/2 adapter interface applications.
 * DOS XGA application in a windows on the PM desktop.
 * DOS VGA graphics applications in a window on the PM desktop.

NOTE: Support of non-interlaced frequencies requires the installation of Service Pak XR06050 for OS/2 V2.00, or the purchase of a system unit pre-installed with OS/2 V2.00.1 or higher. OS/2 V2.00 level does not supply seamless Windows support (only full screen support).

Windows 3.0, 3.1 Environment

Supported applications
 * Windows applications.
 * VGA DOS text mode applications in a window.
 * full screen VGA applications (text or graphics).

Un-supported applications
 * DOS XGA application (full screen or windowed).
 * VGA graphics applications in a window.

NOTE: For above support, the customer must utilize XGA device driver diskette V1.2 or higher.

DOS Environment

Supported applications
 * VGA applications.
 * 132 column text mode applications (written using the BIOS mode 14h call).
 * DOS adapter interface applications (8514/A AI compatibility).
 * XGA applications.
 * applications written to the AI of Image Adapter/A supporting resolutions up to 1024 x 768.

Un-supported applications
 * applications written to the 8514/A hardware registers.

NOTE: For above support, the customer must utilize XGA device driver diskette V1.2 or higher.

The following XGA device drivers will provide XGA function when used with XGA-2 Display Adapter/A and existing PS/2 85XX monitors:
 * OS/2 1.3 Presentation Manager XGA device driver (requires installation of CSD # XR05100 for OS/2 SE v1.3 or CSD # WR05100 for OS/2 EE v1.3)
 * OS/2 2.00 Presentation Manager XGA device driver
 * Microsoft Windows 3.0 XGA device driver
 * AutoCAD release 10 XGA device driver.

No application or driver modifications are required for extended graphics mode on existing PS/2 monitors. Support of new 95XX monitors, however, requires modification to applications and device drivers to implement Display Mode Query and Set (DMQS), a comprehensive new method for identifying monitor and display adapter characteristics. DMQS better enables applications and drivers to maintain compatibility with changes in adapter and monitor products. (Refer to the PS/2 Video Subsystem Technical Reference, S42G-2193-00, for additional information.)

IBM recommends that XGA-2 applications be written to the API's of OS/2 Presentation Manager and Microsoft Windows rather than to the XGA-2 hardware registers or the XGA-2 DOS AI. If writing to the hardware registers, consult the PS/2 XGA Adapter Interface Technical Reference, S15F-2154-00, to ensure XGA/XGA-2 register compatibility. The XGA-2 DOS AI does not support 132 column text mode or direct color mode.
