SYMPTOMS
If you have a dual screen system operating at a high resolution (2048 pixels wide across both screens, and more than 64K colors), and your hardware does not support OPENGL, you may have trouble with the right side of the display after performing a screen update.



CAUSE
The viewport limit is currently set to 2K. This is insufficient to hold information necessary for such a large resolution. Any information that cannot be held is not updated.



STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.51. This problem was corrected in the latest Windows NT 3.51 U.S. Service Pack. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
