KVM switch and Vista Beta 2 Video

    I am running a GeForce 6800 GT card with the 88.61 Nvidia drivers.

    I run a KVM switch so I can use 2 computers. One with Vista and the other
    with XP. I mentioned earlier when I switch from one computer to the other,
    I get a device connect or disconnect alert. I have also noticed, if I do
    not have the Vista computer selected and it goes into a screen saver mode,
    if I switch back to it, there is no video signal. I have tried hitting keys
    to "wake it up" with no effect, hence I have to restart.

    If I hit the power button, Vista will go through a shutdown cycle and
    occasionally, the video will return when it displays the "windows is
    shutting down" screen.

    Has anyone else seen this?

    Is there an approved KVM switch for Vista, since I did not see one?

    Could it be related to the Nvidia drivers?

    Are there any key combinations or any other way to wake up the video signal?

  2. I have a similar problem that when I'll turn my monitors off if I'm not
    going to be using the computer for awhile and when I turn them back on my
    primary monitor doesn't come back but my secondary is unaffected. I don't
    yet know what the cause of the problem is though.

  3. I am having a similar problem. I have a 6600GT with the Nvidia drivers. I
    also have a 4-port KVM switch. However, I only use it to switch the monitors.
    I have a seperate keyb/mouse for each machine. (using the KVM causes repsonse
    problems with gaming for me) In XP I could switch the monitor to my server
    whenever. With Vista, when I do this I hear the device disconnect sound and
    my resolution goes to like 800x600 and just one monitor. When I switch back I
    hear the device connect sound and I have to re-setup the monitors all over
    again. It is needless to say this is annoying and I have no idea if it is the
    drivers or the OS itself. Any suggestions would be welcome.

  4. I am having almost identical problems as this. I am using a 6600GT card with
    the nvidia drivers. I find the sounds are identical and i have to re-setup
    the screen everytime.

  6. To all that have this problem, seems that some KVM's when switched off the
    system drop the video signal. Vista can detect when a monitor is unplugged
    from most modern video cards, hence the disconnect sound. I have 2
    different KVM's and have noticed that one of them does this, and the other
    does not. Tested it by directly hooking up a monitor and unplugging it, I
    also get the disconnect sound. So KVM issue, not vista. Weird thing is my
    KVM that does not work is a nicer Belkin 4 port model, the one that works
    fine is a low end Zonet 4 porter.
