#Speedstar 64 and NT 3.5
4 messages in this thread
I recently installed a Speedstar 64 in my DECpc 450ST. I'm running Windows NT
3.5 and I'm having some problems with the drivers that come with NT 3.5.
Whichever 1280×1024 mode I pick, the display is always interlaced. Yet of the
modes listed only one is marked as interlaced.
With Windows 3.1 I managed to get 1280×1024 @60Hz without interlace, though the
picture flickers somewhat. On NT, the frequences go from 45Hz up to 71Hz.
I'm using 1024×768 currently on NT simply because it works and it isn't
interlaced. My original graphics card could drive my screen at 1280×1024 with
no problems but isn't supported by NT3.5.
When I was trying out the highest resolution mode, I had problems returning to
VGA. My monitor would display a 'horizontal sync out of range' when I shut down
NT. On one occaison, VGA worked but I got a screenful of garbage.
Even more curious is a friend with the same screen and card – he manages to get
the high res mode without problems. NT reports the video drivers 'out of date'
when he tries the Control Panel Display applet.
Any ideas?
Pete.

I am considering buying NT3,5 Workstation. How do you like it? Is support for
the SS64 built-in (I have one also)? Thanks!
NT 3.5 has drivers for the SS64 built in. I'm not sure why they don't appear to
be working properly on my system.
As for NT itself, it seems to do everything I could do with Windows 3.1. Since
I'm writing software for Windows, it's a great development platform.

Our testing here has also produced the same results. This may be a
configuration issue or a limitation of the driver. I would recommend contacting
Microsoft regarding this issue.

It sounds like he has installed our Windows NT 3.1 drivers.
