Dear netlanders,
we have the following problems in connection with video boards,
monitors and Windows 3.0:
Prolog:
We had to exchange the video boards (noname with 1 Meg RAM) of
5 newly purchased PCs which worked perfectly with Windows,
because the Tseng Lab 4000 chip set does not work properly
with DigiTalk's Smalltalk/V 286, which is our basic
development tool (we will port our application to Smalltalk/V
Windows in the medium range). This incompatibility (scrambled
fonts, menu items disappearing) is a known problem (for
users!); any responsible is rejected by either of the
companies. So we decided to get boards three times the price
of the Tseng based card: ATI VGA Wonder plus/512K.
Problem 1:
When using any of the advanced video modes supported by the
Window-drivers which came with the new boards it is not
possible to switch back from a DOS application running in DOS-
mode to Windows: The screen in the upper third is scrambled.
Windows still reacts to keyboard events like it should. This
problem only appears with the new monitors we bought: TAXAN
795 with 1024x768 resolution non-interlaced. Everything is ok
with our old monitors, EIZO 9070S. This problem does not occur
with the Optima card and the TAXAN monitor.
The ATI-drivers are dated November 1990.
Problem 2:
All 256 colour modes of the ATI Wonder + do not work properly
with either monitor: all portions of the screen touched by the
moving cursor, especially window borders and text get
scrambled (but not unreadable).
System-Info:
We use 386SX boards with 4MB RAM, have Windows installed on a
Novell server, use ethernet cards, NetWare SFT 2.15.
Please respond by e-mail because we have a very fast garbage
collector for netnews....
Thank you very much -
Thomas
