Dual Screens at High Resolutions Don't Display Correctly

ID: Q154983

The information in this article applies to:

Microsoft Windows NT Workstation versions 3.5, 3.51
Microsoft Windows NT Server versions 3.5, 3.51

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):
