Hello everybody,
has anybody successfully connected a DEC 17" monitor VRT17-PA to a
Intel-based PC? How? Which graphics adapter? Which driver?
Is this monitor identical to a Sony 17se?
Can anybody list the differences in the technical specifications (e.g. timings)
between this monitor and a "standard" PC monitor?
Can I operate a DEC ZLXp-E1 PCI graphics card in an Intel-based PC and then
connect the VRT17-PA to it?
Which drivers for Windows95? Where from?
Background information:
We bought an AlphaStation 600 5/266 with a ZLXp-E1 graphics adapter and the
already mentioned VRT17-PA monitor. Xwindows applications on DU display O.K.
(excellent picture) on this combination.
We use this workstation as a kind of server, so we don't need the console
display, and I tried to attach the monitor to a PC (Motherboard: ASUS SP3G)
with a PCI graphics card: SPEA V7 MIRAGE P-64. (video chip: S3 Vision864,
RAMDAC ATT20C498/ATT21C498, up to 135MHz, 2MB graphics memory) (this has
been successfully operated before with a Sony 15sf)
Result: Dramatic Convergence problems at the upper right and lower left
border. Cannot be corrected with the built-in monitor controls. Same
problems at all available frequencies, resolutions and jumper settings
(Maybe I missed some combinations of these parameters :-)
Similar results with a new Hercules graphics adapter (don't know the exact
model) on a different PC.
Picture is visible at all frequencies, so this monitor is _NOT_ a
fixed-frequency monitor as were the old DEC ones. Seems as if the fly-back
timing is different compared to "standard PC" monitors. Is it possible to
change the timings in the S3 chip on the graphics card? How?
Any other suggestions?
Thanks in advance for your ideas
