Had a faulty Idek 17" VDU, replaced with one seen working ok. Idek & others
are of the opinion that the remaining problem is due to the G.Card, a DS64
2MB *DRAM* which had a very chequered history.
Prob: 1024@72Hz - text has light-patch ghosting after text.
1280@72Hz - unusable.
Both @60Hz - matters improve
Matrox/Orchid - no problem!
... so the card is suspected as faulty or not up to it in terms
of bandwidth (RAMDAC of 135MHz + DRAM + 1280 = poor mix).
Solution:
- I have the option of exchanging the card for a DS64 Video? VRAM card,
which I am told will provide a better quality image.
- BUT I have a few questions here! ...
o DS64 Video VRAM ok under - Linux & Windows95:347 (Beta) ?
o What are the known driver problems ? (long AFAIK)
o Are there two RAMDAC versions, 175 & 220MHz, available ?
Many thanks for replies.
(If the card is definately faulty they will replace it, if it's a matter
of 'well they are just poor at 1280@72' they will replace with a VRAM.)
