[comp.sys.ibm.pc] Problems with Video7 VEGA-VGA

kirchner@uklirb.UUCP (Reinhard Kirchner) (11/21/88)

Hello,
I do have some strange behaviour of my VGA-Card.
The configuration:
Epson Equity III+
Video-7 VEGA-VGA
NEC Multisync II

When I display some graphics in CGA-Mode ( must be, are Demo-floppies -8),
sometimes the screen show every second pixel-line shiftet appr. 1 cm to the
right, so a vertical line looks a little like

---------*----------
--------------*----
---------*----------
--------------*-----
---------*----------
--------------*-----

This is not constant, it comes and goes for minutes. Now even more strange:
It happens only in the leftmost slot ( Number 1 ), I then put the card
into the rightmost slot ( Number 9 ), where it works.

I used the card for some time in an XT-286, also leftmost slot, without that
problem.

Does anybody on the net have or here about this or similar things with
Video-7 VGA? My Problem: is the computer or the VGA to defect?

BTW: I asked Epson-Germany, they could not help me ( would be a wonder if ),
     but they told me: the Video-7 VEGA-VGA does not work under OS/2 !
     It looses syncronization totally. They named other cards which work,
     namely the EIZO and the Paradise ( EIZO uses Paradise chips ).
     So the Video-7 may not be as compatible as everybody says ( and writes ).

Please send comments to these things to the net, not by mail to me, since
many may be interrested.
