BUG: GDI Limits DirectDraw Surfaces to 2048x2048 (171249)
The information in this article applies to:
- Microsoft Win32 Device Driver Kit (DDK) for Windows NT 4.0
This article was previously published under Q171249 SYMPTOMS
When an application tries to open a direct draw surface greater than
2048x2048, the call fails at the GDI layer. This can happen even when the
video driver supports resolutions greater than 2048x2048.
CAUSE
The Windows Graphics subsystem range tests requests for direct draw surface
dimensions. These are compile time constants that dictate the minimum and
maximum values. These values are set to 2048x2048.
RESOLUTION
The only workaround is to stay within the current maximum resolution of
2048 X 2048.
STATUS
Microsoft has confirmed this to be a problem in Windows NT version 4.0. A
fix to this problem is in development, but has not been regression-tested
and may be destabilizing in production environments. Microsoft does not
recommend implementing this fix at this time. Contact Microsoft Technical
Support for more information on the availability of this fix.
Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.
