Switch for Using One Monitor w/2 CPUs?

In passing, I heard someone refer to some sort of switch that can be used to share 1 monitor w/two CPUs. I already have a setup w/2 monitors on my G5, but I need to get a cheap-o PC tower to run a couple of programs. REALLY don't want to use Virtual PC and I don't want to buy a new Intel Mac quite yet. So regardless, this switch is supposed to be able to help you go back and forth between the Mac and the PC on one monitor.
Any leads on who might manufactor something like this? And any experiences, good, bad, etc?
Thanks!

Hello! You are referring to a kvm (keyboard, video, mouse) switch. They're a couple of types (usb and ps2). You'll have better luck trying to use a usb type but be sure the pc has usb ports. I have 3 pc's and 1 mac connected using a kvm and like it fine. There are several companies that make them. One is Monoprice.com which is where I got mine but the model I have is discontinued. Here's some links. Tom

  • Ho do I use one monitor for OSX and Windows 8.1 bootcamp

    I am a long time Mac user, but find the fairly recent Apple switch to thunderbolt for monitor input very frustrating.
    For several years I have ran a Mid 2010 IMac 27" and input video from a Mac Mini running Boot Camp Windows 7 using Target Display Mode on the IMac. 
    This worked fine until I upgraded to a Late 2013 27" IMac and discovered that the  IMac has moved to thunderbolt as the input for Target Display Mode.  The new late 2013 27" IMac just will not display native Windows 7 or 8 from a Boot Camp Mac anymore.
    My problem is that I have two business/job related Windows apps that must run on a native windows 7 or 8 platform, and won't function under either Parallels or VMWare Fusion.
    I have tried. 
    And there appears to be no way to get any Windows machine with DVI or Mini Display Port output to drive a late 2013 IMac in Target Display mode.
    So, with great frustration, I have concluded that I need to purchase a non-Apple 27-30" monitor, and drive it with either a Mac Mini, or my Early 2013 15" MacBook Pro retina, running one of the Macs into on of the mini-Display Ports on the monitor and a native Windows 7 or 8 machine into a second mini-display port, switching between the two video inputs.   The Dell 30" monitor seems to get the nod.
    Has anyone found a better solution to switching between OSX and native Windows on one monitor?
    Thanks...

    Hi William,
    I had the same experience in December 2013 and contacted Apple about it. According to Apple it's an issue of Windows with Thunderbolt. Your older iMac from 2010 is using DisplayPort and not Thunderbolt for the Target Display Mode. Note that just the connector looks the same but it's still a different technology. Please further note that the response below does not apply for the new iMac 27" with the 5K display because this iMac does not support Target Display Mode at all, hence can't be used as external display. Of course you can still attach one or two external displays to the iMac 27" 5K.
    Hope this clears things up for you and the others.
    Thanks,
    Martin
    So, here is the important part of the official response from Apple:
    "... The Thunderbolt controller in an iMac is running exclusively in host mode. As such it cannot emulate a device mode Thunderbolt display. Instead it implements a custom Target Display Mode protocol that shares video between two peer to peer machines running with both controllers running in host mode. The "client" side of the driver does not exist on Windows so windows cannot speak to the "server" half in the iMac. There are no plans to implement a client driver for Windows since there is no Thunderbolt SW stack available for Windows. The reason this used to work is that the older iMacs used DisplayPort for Target Display Mode. In this scenario the iMac was able to expose the panel in such a way that it looked exactly like a Display Port Device which Windows does have driver support for. ... "

  • How to use one monitor with two Power Macs

    I searched this forum and was unable to find an answer. Although I believe it's probably here.
    Nevertheless, I have a Power Mac G5 and a rarely used Power Mac G3. I'd like to share the G5's VGA Accusync 120 CRT monitor with the G3. I know there is a way to switch the monitor between computers without pulling plugs in and out of the machines.
    Does anyone have any specific switch I could buy to solve this issue. I don't care so much for picture quality for the G3. But I don't want to compromise picture quality for the G5.

    You're looking for what's called a KVM (Keyboard, Video, Mouse) switch.
    This one should do what you're looking for. I've not used it, but it does VGA switching like you want and is inexpensive.

  • Can I daisy chain two mac pros so that I'm using one monitor and keyboard

    Can I use two mac pro's with one monitor, keyboard & mouse? The two different machines have two different operating systems (Snow Leopard / Lion). One machine is brand new and the other is 5 or 6 years old.
    I want to use both machines in tandem so that I can leave something to render while I work on something else.

    KVM is an answer -- maybe.  I use one for two machines to share one of my monitors (a VGA) and my keyboard (the second older machine seems to have sleep problems if I share a usb mouse on the kvm however).
    The trickiest part of choosing a kvm is trying to find one that can handle the video; one that can handle the required bandwidth, and the connections.  If one computer uses, say DVI, and the other mini-displayport, then you need to figure out which kvm can handle that with one (or both) of the machines using adapter(s). 
    You said one of the machines is brand new.  Then it probably has thunderbolt.  So you would need a mini-displayport, dvi, or vga adapter depending on the monitor.  That means the older machine will need a similar connection since whatever kvm you get will have the same kind of ports for both inputs and its output.
    A wild card here (at least in my mind) is if the newer machine has thunderbolt.  While a mini-displayport display can be plugged into a TB connection, it is not clear that such a thing will work through a kvm.  That is unknown territory I think at this point.

  • Proceedure for using external monitor - help

    I have a 2nd Gen MacBookPro with the FW800.
    I was told that in order to properly utilize my external flat screen monitor I have to do the following:
    1. Plug in external keyboard and mouse (not the monitor)
    2. Start the laptop and log in using the laptop monitor
    3. Once all is running, close the laptop lid, wait for the computer to go to sleep then connect the external DVI monitor.
    4. Wake up the computer and the external monitor will display correctly.
    This does work but is a pain.
    If I connect the external monitor in the beginning, and then close the lid, the display is distorted (maybe simply a much lower resolution).
    Is this normal? I was thinking about buying a dock and the benefit would be diminished if I still had to go through all this.

    This process is only necessary if you are really constrained for space. Having both the MacBook's display and the monitor open simultaneously you get an extended desktop to move windows around. Closing your display, you lose a lot of workspace.
    Yes it is distorted at the lowest resolutions. Though some monitors have better support for the progressive scan built-in to the MacBook Pro than others.
    Also if your monitor is a 4:3 ratio display, the 16:9 "stretched" resolutions will appear distorted because you are trying to fit rectangular pixels on square ones!
    Use a non-stretched resolution if you want less distortion on a 4:3 display, if that's what it is.

  • Using one monitor/keyboard/mouse with Mini

    Good morning.
    I'd like to have one of my minis connected to a monitor/keyboard and mouse that would be shared with a Windows systems.
    What is the best device I can use to accomplish this? What type of connections should I look for, etc.
    Thanks.

    For best video performance you should look for a KVM that used DVI outputs although it's not important of you are using VGA display with no DVI support. BGreg's post gives you all the information you need on that score.
    Now, another option if you don't already have a display or you are thinking of replacing your display is to go a model that has multiple video inputs (which are easily selectable) and has an in-built USB hub. By doing this you can connect your mini to one video input (hopefuly DVI) and the PC into another (probably VGA) and simply select between them. As for the keyboard and mouse, you plug them into a USB port on the display and all you them have to do is to swap the uplink to whichever computer you want to use.
    While not quite as nice as an external KVM solution (having to swap cables whereas on a KVM you push a button) I think you will get better video performance as both computers are directly connected to the display and don't need to go through another device. Additionally it will more than likely be cheaper overall as good KVMs can get quite expensive and you can put that cost into getting a better display. My Dell 2405FPW will work (future tense as my mini still hasn't appeared out from the shipping ether - I think I've upset the shipping Gods in some way) perfectly in this way.

  • Connecting two Mac minis and using one monitor

    I am thinking about getting two Mac minis to run concurrently, accessing both on the same Thunderbolt Display (also to be acquired) using screen sharing and connecting the two Macs via firewire (or thunderbolt).
    I have certain programs I need to run in Windows (Bloomberg terminal and MS Excel in Windows version) but don't want to run them in parallel on one computer as (in my experience) the performance is very slow.
    By running two computers at the same time, I'm hoping that can avoid the entire system griding to a halt. I also think it will allow me to upgrade more cheaply as the Mac mini is improved over time.
    Is this a completely daft idea? Would I be better off with a new iMac or a refurbish Mac Pro?
    Any feedback is welcome, even of the abusive variety.

    "File sharing preferences" is indeed how to do it.  Connect both minis to your router (one by ethernet cable, one by wifi, it doesn't matter.)
    Then turn on "File Sharing" in Sharing Prefs on both minis.  Also, give them both meaningful, different names under "Computer Name".
    Then, when you open a finder window on one mini, the other one should appear under "Shared", like this:

  • Using LMS 3.2 to setup switches for archive config

    Is there a way in LMS 3.2 to setup switches for using the archive config feature such that the filename could be automatically set to be the switch mgmt address or hostname?
    So for the below example:
    archive
    log config
      logging enable
      notify syslog contenttype plaintext
    path disk0:switch01.archive
    write-memory
    time-period 1440
    Would there be a way to set (I'm guessing in netconfig) "path disk0:switch01.archive" with something like "path disk0:$HOSTNAME.archive" or "path disk0:$IP.archive" ?
    -Dave

    Nevermind. Figured out that there are variables in the path that I can use for this:
    $h - hostname
    $t - timestamp
    archive
    log config
      logging enable
      notify syslog contenttype plaintext
    path disk0:$h-Backup-$t
    write-memory

  • How can i use two monitors in my application?

    Hello,
    Background
    I have a dual monitor card and two monitors which I want to use in my LabView application. The application gathers data from a complex sensor and calculates a number of results which need to be displayed graphically, this happens every 10 seconds or so. There is an awful lot of graphs which may be needed to be seen at some time but not routinely. The idea is that one monitor will display all the standard routinely displayed things and will not have any user input whilst the second monitor will display a tab control which has all the other graphs pickable.
    Question
    What I want to know is how I can programmatically tell labVIEW to put one vi up in one monitor and another vi in the other. I would then have them both maximised (which I know how to do). I would rather have the monitors set up as individual and that way I could keep the windows control bar on one monitor only. Thus one monitor would be a true user interface and the other simply a display.
    Basically how do I tell LabVIEW to use one monitor for a specific vi and not the other.
    The card I have is a matrox p650. Any comments would be appreciated.
    Regards
    Kevin

    Hallo,
    with new version of LV its more easy, but it also hasn't any troubles with LabVIEW 6.x or 7.x.
    Especially with Matrox P650 you will get no any problems (we using
    exactly this card together with G550 and our application supported
    three monitors at the same time.).
    I recommend to you following sequence:
    - After installing driver turn on option for supporting different
    resoluton on different monitors. As result you will get two absolutely
    separate monitors.
    - In Windows define which one is primary and which one is secondary.
    (On primary monitor located taskbar and all messages dialog boxes will
    appear.).
    - Arrange secondary monitor in display properties - where he located (left from primary, or right)
    - In your VI (which must appear on second monitor) use
    FrontPanel.PanelBounds Property Node for positioning. You must set four
    values for two corners. Easiest way to found right values is following:
    read this property node in while loop and put indicator on front panel.
    Then run VI, drag front panel onto second monitor and resize if
    necessary, and then you will see right values for PanelBounds. You can
    write this property node programmatically in run-time too.
    hope it help,
    good luck.

  • I can't use dual monitors since upgrading to Lion

    I use my HD TV as a second monitor for streaming movies etc.  Since upgrading to Lion, I can only use one monitor at a time.  Is anyone else having this problem?
    Thanks

    Yes, the blanking of secondary monitors is an issue.
    In fact, it is the reason why I went back to Snow Leopard on my 3-screen iMac
    I encourage you to contact Apple with feedback
    I have taken the following actions:-
    Provided feedback to Apple viahttp://www.apple.com/feedback/aperture.html
    Provided feedback to Apple viahttp://www.apple.com/feedback/macosx.html
    Submitted a bug/enhancement request via my free Apple Developer account
    Written to pretty much every mainstream Mac publication
    Encouraged every poster, like yourself, to raise this with Apple in your own words
    Next week, I will call Apple Support under the AppleCare agreement for my iMac
    Please give them feedback, and we might get this silly design decision changed.

  • How to use one module pool program in another module pool programming?

    Hi
    I have one moodule pool program.
    In one of my screen i want to use some code which already developed in another module pool program.
    Is there any direct way for using one module pool programcode  in another module pool program.
    If there any approaches for this plz help me in this issue.

    Dear,
    If you want to use the code.
    first you can write your code in a subroutine in module pool program 1
    and then you can use it from module pool  program 2 by
    perform subroutine_name(program_name)
    using P_1
    changing C_1
    if you wan to use one module pool data into other module pool.
    so that is another requirement.
