One monitor magically turns to three.

    I've recently switched video cards from a GeForce 2 MX to a GeForce 4 MX and did a fresh install (uninstall and reinstall) of the same drivers (Omega). The problem is, my computer is convinced that I have three monitors, when I only have one. Even when I try to remove the clones from the device manager, Windows (98 SE) keeps detecting it to bring it back (for the fun of it, I changed the two "Default Monitors" to use my Samsung drivers). I'm trying to see if the NVidia drivers have any settings to turn off for something along the lines of "multiple monitor support," but I can't seem to find any.

    Here's a link to show you what I mean.

    Did you remove ALL the monitors and reboot?

    That was my first act to deal with this issue. And no that didn't work as all three returned. I'm assuming the only way to "remove" the monitors are to simply delete their entries on the device manager. Interestingly enough, the first-party drivers (Samsung) do not have an entry in the add/remove programs.

    Hi K-16
    Did you remove the ghost devices while in Safe Mode?

    Ok now I'm stuck with two. After removing all three again without using safe mode, only two returned (both as default monitor, but I changed them to my Samsung drivers). I'm going to assume I removed two instead of three last time and that I need to get my head examined. That said, I tried safe mode just now with no luck. Two monitors returned. I'm assuming one monitor is a fake. I still think it's the NVidia driver, but I don't know where the option is to disable whatever is causing this.

    What exactly does it say for the two monitors? The reason I ask is my nVidia dual monitor setup actually displays four, like this:

    The one on the right is the safe mode version. And for the record, the safe mode version has the bottom two as "Default Monitor" while the one on the left has both as "Default Monitor" before I made the driver change. I suppose I could be stuck with two monitors if NVidia does not have an option to disable multi-monitor setups.

    You could always just uncheck the "extend my desktop onto this monitor" in the windows native display properties. I'm somewhat certain that the nVidia driver automatically sets up dual monitor support and that extra monitor appears whether you have a monitor or not. It's basically just detecting a dual head video card.

    Well the main monitor selection has that option checked and grayed out, while the other selection already is unchecked. Should I start thinking that this is a feature and not an issue at all whatsoever?
