How do you change monitor type in win2k?

[fburleigh]

My Geforce 256 card's fan became noisy and was replaced by a Geforce 2 MX card (Visiontek), 32mb, apparently ddr, on a win2k box. I had run the Hitachi CM812 at 1920x1440x16bpp at 72hz. However, the new card with the latest Nvidia 6.5 driver only offers me 60hz at 1920x1440 no matter the color depth. It is also odd that the "monitor" tab in the display settings dialog claims the monitor to be "Default monitor" with the "properties" button unavailable, meaning presumably I can't change the monitor type, at least not by that method.

I got mon_inf.exe from Hitachi support, unpacked it, right clicked hitachi.inf and ran the "Install" option but nothing seemed to happen. In the registry I see both "Default monitor" and the Hitachi CM812. "Default monitor" may in fact refer to the Hitachi, but I can't really tell. I use another win2k machine on the same monitor (using a switch box), and its monitor setting does in fact read CM812.

One final point: the CM812 manual claims the max resolution is 1200x1600. I discovered by accident that the monitor can do higher resolutions and rates, and that's how I've been running for a year.

Any advice is appreciated.

Go to device manager and delete the entries for your monitor, then while still in device manager, right click and scan for hardware changes, windows will find a new device, pick the second choice and point it to your inf file.

Also be careful about unsupported resolutions, your monitor is usually the piece of hardware you keep the longest before an upgrade, you could damage or certainly reduce its lifespan.

Thanks for your reply. This is one of the odd things: there is *no* Monitor item within the device manager, therefore I can't delete a monitor.

I had progress this morning using this technique:
- visited visiontek, downloaded 6.31 driver (not the latest 6.5 driver);
- safe mode, device manager, properties for the nvidia card, driver, uninstall. This had the effect of removing the display item from device manager.
- reboot, go through new hardware wizard, chose 6.31 driver.
- reboot, and now I have the refresh rates and resolutions known for the nvidia device.

I'm happy that I'm where I was, but now don't know whether I've merely "shaken" something or whether the 6.50 driver caused this problem to begin with. I'm now afraid to mess with it for fear the success isn't reproducible. ;-)

And I still have a Monitor folder in the device manager, and the Monitor tab of the display dialog still reads Default Monitor with its Properties button still not available.

Any thoughts in these behaviors?

I have the exact same problems using my Radeon on my Mitsu Pro900. Still haven't found a solutions yet..
