GeForce 7800GT - latest drivers - TV Out Resolution issue

Discussion in 'Nvidia' started by rhox, Jan 18, 2007.

    I used to use my television (NTSC) as a second monitor, had it running
    last night actually, and in the NVIDIA control panel I could change both
    my monitor's resolution and my television's resolution independently.
    Now, however, my only choice is to have both of them act as a horizontal
    span. How can I make it so that I can use "Dualview" like before and
    switch the resolutions separately?

    I have a FX5600 and ran into this problem before too. The solution
    that worked for me was to set the display properties to a single
    monitor. Make sure that the TV is connected so it's detected on
    boot-up. To know if it's working, you should see your motherboard
    logo (windows logo) when the computer starts. This action is what
    displays the dual-view option in Nvidia's control panel. I don't
    know why the dual-view option disappears now and then but that's
    how I was able to get it back.

    Thanks Sam, that works. I just wish I didn't have to reboot anytime I
    want to re-enable Dualview.

    Glad to hear it worked. I know what you mean, I hate rebooting too,
    it's annoying. At least now we know it's a software issue and not
    hardware since we both have different cards. When I get a chance,
    I'm going to let Nvidia know about the problem and hopefully it'll
    get fixed in the near future.

    Mhmm. It doesn't happen with two actual monitors.

    With two monitors, you can change the settings on the fly without
    losing the dual-view option?

    Yeah, I use DualView and two monitors fulltime, occasionally add a
    third. All mine are on DVI, but that doesn't make a difference to the
    DualView. What does make a negative difference (IMO) is coming out of
    SLI everything has to be redone, even when saving/loading profile. And,
    the driver still requires a reboot going into and coming out of SLI.
    Crap. But you can change all the other display settings on the fly
    without rebooting.

    Actually I'm not sure. I haven't tried to disconnect the 2nd monitor
    while leaving the computer on and replugging it.

    I didn't structure my question very clearly. I wasn't referring to
    disconnecting and replugging the second monitor. I was trying to
    confirm what I 'thought' you said. Did you mean with a 2 monitor
    setup, you don't lose the dual-view option when you make changes
    like you can with the tv & monitor setup? Or where you refering to
    not having to reboot when you said, "It doesn't happen with two
    actual monitors."?

    Scalable Link Interface. It combines the use of two (or even more)
    GPUs to accelerate full screen 3D apps for one display. Some 3D
    applications probably make use of it for real time display of 3D scenes
    being modelled. For most of us, games benefit from increased
    performance, even at higher resolutions.
    The current nature of this form of SLI means that multiple displays
    aren't possible. You have your choice of which connected display to use
    when going to SLI mode.
    It's, in short, another way to Go Faster.

    I meant that I don't lose the Dualview option if I change back to single
    display mode.

    That's a really interesting point that you brought up. My initial
    thought of being a software issue was incorrect, it is a hardware
    limitation. Now it makes sence. A monitor is able to operate with a
    bi-directional signal of sending and receiving where a standard TV
    only receives. The software doesn't receive a signal back from the
    TV and by default hides the dualview option. It's not likely that
    Nvidia can fix this problem. Looks like we're stuck with this
    annoying feature.

    That's interesting, I'm going to look more into this. Thanks for

    I didn't know that. Thanks for the extra knowledge, Sam. Sounds
    understandable. I don't like having to reboot, but it isn't something
    that is too hard to deal with. I don't use the TV all that much, so it
    should be fine.
