XGA-2 Display Adapter/A - Monitor Compatibility

Applicable to: World-Wide

The following are examples of the resolutions that are available with the XGA-2 Display Adapter/A when running XGA applications or device drivers that exploit DMQS, cross-referenced with the resolutions supported by IBM monitors. The XGA-2 Display Adapter/A is limited only by a maximum PEL clock rate of 90MHz. Many other IBM and non-IBM SVGA monitors will work with the XGA-2 adapter, in all mutually compatible resolution/color/frequency modes.

*1	These monitors are designed to operate with any video controller that meets the following specs:
	Addressability range - 640x480 to 1280x1024; and
	Horizontal Frequency range (Line Rate) - 30 to 64 KHz; and
	Vertical frequency range (Frame Refresh) - 50 to 130 Hz non-interlaced

*2	These monitors are designed to operate with any video controller that meets the following specs:
	Addressability range - 640x480 to 1280x1024; and
	Horizontal Frequency range (Line Rate) - 30 to 64 KHz; and
	Vertical frequency range (Frame Refresh) - 50 to 110 Hz non-interlaced

*3	These monitors are designed to operate with any video controller that meets the following specs:
	Addressability range - 640x480 to 1360x1024 (9527) or 1600x1200 (9521); and
	Vertical frequency range (Frame Refresh) - 50 to 110 Hz non-interlaced
	Video Input Signal: Analog, direct drive, 75 ohms, 0-0.7V

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 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 default screen resolution to be over-ridden. Over-riding with a resolution which does not meet (or exceeds) the capability of the attached display, can yield unpredictable results.

Warning: Some multifrequency displays may appear to function correctly, however damage may occur over time.

Note: Only resolutions that are suitable for the display attached to the XGA-2 Display Adapter/A must be selected.

Note: 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.
