Note that 16 color resolutions are not supported at this time for the Vision864 product. Known Limitations - ADI 4.2: 1. AutoCAD 11, 12 - With a combination of dual screen mode and shell edit, ACAD screen is corrupted. The problem occurs in all resolutions under AutoCAD 11, and only 640x480x8 in AutoCAD 12. Use the command "REINIT S" to correct the display (only in ACAD 12). 2.

Pressing the space bar in this condition causes the command prior to the last one to appear. 3. AutoCAD 12 AVE - REPLAY IMAGE to a non-black screen will result in inaccurate colors in the replayed image. 4.
