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 NT reports the video drivers 'out of date' when he tries the Control Panel Display applet.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.

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. Pete

This may be a configuration issue or a limitation of the driver. I would recommend contacting Microsoft regarding this issue. >>>>>Even more curious is a friend with the same screen and card – he manages to get the high res mode without problems.
