Connecting to PC Monitor with KVM Switch

I'm still setting up my new MacBook Pro laptop. I thought it would be nice to take advantage of my 21" PC monitor while I'm at home, so I purchased my first KVM switch.
I plugged everything in as instructed, and it appears to be working at about 75%. In other words, I can use my mouse and keyboard with my PC just fine, and when I click the Scroll Lock key twice, the monitor shifts to Apple mode; it has the same bluish background my laptop does.
However, it doesn't display anything I see on my laptop's built-in monitor - the menu bar, open programs, etc. Curiously, it displays one folder, titled "untitled folder 3." My mouse works, though there's nothing for it to manipulate, save one empty folder. I can't tell if the keyboard works or not. The trackpad that's built into my laptop also works on my PC monitor. In other words, I can move the cursor on my larger PC monitor with either the mouse or the trackpad.
Next, I reversed the wires, plugging the PC into the KVM node that had formerly connected to my MacBook Pro and vice versa. The results are pretty much the same, except that now when I toggle to Apple mode, my mouse moves the cursor on the laptop's built in monitor, not on the larger PC monitor. Also, my MacBook told me it didn't recognize my keyboard, so I replaced it with a Mac-compatible keyboard. (I learned how to do the hot key trick so I can toggle by hitting the CTRL key twice.)
So my KVM switch is obviously almost working. I just have to convince my laptop to ignore its built in monitor and display everything on my PC monitor, not just one empty folder. Can anyone tell me what's going on, and how to fix it? Thanks.

Though for 10.3 this will work for 10.4

2nd Monitor with KVM switch

hi,
i work for a major broadcast company who use a MacPros for trade shows (NAB, IBC etc) with a mirrored output.
monitor two goes directly into a 23" Cinema Display.
monitor one goes onto a geffen KVM to a 42" panasonic plasma running at the same resolution as the cinema display.
when we switch back to the mac from another computer the cinema display seems to run an autodetect again and takes sometimes up to 30secs to detect, correct and return to use (so we can keep using the k+m).
does anyone know a way to disable this autodetect? i can't seem to find anything, neither can the apple people i've spoken to. i've tried using a single geffen DVI splitter but with similar results.
thanks

i think i can get hold of some to test. thanks.
is there no unix code i can apply to disable the autodetect? i've applied code for various other "niggles" we've had to great success, i'm just not sure about this one.
thanks.

Can I use the HDMI out on a HP ALL IN ONE TOUCHSCREEN Desktop to connect a second monitor with HDMI

Can I use the HDMI out on a HP ALL IN ONE TOUCHSCREEN Desktop to connect a second monitor with HDMI in without any additional software or graphics adaptor. I have a 520-1070
HP - 23" Touch-Screen TouchSmart All-In-One Computer - 8GB Memory - 2TB Hard Drive ? I used a HDMI to HDMI cable and the monitor was not recognized.

Here are the specs for your HP TouchSmart 520-1070 Desktop Computer. As previously stated your computer Doesn't have a HDMI output, instead it has a HDMI input. This is designed to let you connect a game console, a DVD/Bluray player, etc. to use as a monitor.
If you wish to conect a second monitor to your computer, you will need to use a USB-to-video adapter such as the EVGA UV Plus+ UV39 or EVGA UV Plus+ UV19. Using an adapter like these with the touch feature of your computer may cause issues with pointer control and you may need to disable the touch feature to use "extended desktop".

When connected to lg monitor with hdmi cable i get no sound

when connected to lg monitor with hdmi cable i get no sound

The issue here is that HDMI cables, as the name indicates, carry audio signals to the monitor. Therefore if the monitor has no built in speakers then there will be no sound. If you have external speakers you can plug them into the audio out slot on the back of the monitor and the problem will be solved.
However, if the screen does have built in speakers you need to go Control Panel>Hardware and Sound>Manage Audio Devices and set either your headphone jack or the screen to be the default device. And then you ca pick which device the sound will play from. Either yourlaptop speakers or whateer speakers are plugged into the laptop or the Monitor and whatever speakers are plugged into the monitor

Monitor blacks out when booting with KVM Switch in the middle

Hi
I have attached my Xserve with an iMac G5 to a KVM Switch. When I boot up the Xserve the monitor blacks out after the apple logo.
I know that the Xserve tries to autodetect the monitor. Apparently it fails in its job when the KVM is in the middle. Everything works well when I remove the KVM and connect the monitor directly to Xserve.
Any ideas how do I disable the monitor autodetect feature - or something?
Xserve (intel) Mac OS X (10.4.1) dkvm-4u KVM switch

Hi all
I did try that. No luck.. Strangely enough, I realized that when the server boots up, the login screen defaults to 85HZ refresh rate. I found a site that explains the plist file that you can change to force it to 60HZ. What is weird it if I boot the Mac connected to another LCD, then move the cable to the KVM, it works. It almost seems like when the mac is booting, it sends some sort of signal just before the login screen comes up, that screws up this KVM. Tried updating firmware, still in the process of speaking with the KVM support people...
very strange..

Mac mini with KVM switch

I'm thinking of getting a Mac mini, but I need my Windows PC for some apps that aren't available on Mac and some other stuff. I can't afford to get a large monitor for a Mini if I get one, but my current PC has a big flat panel display.I noticed the KVM cable way of moving your stuff (a cale taht lets peripherals like monitors, keyboard and mice be connected to two computers so you don't need a separate one for eache computer), and was wondering if that's a possible way of using both without buying monitors, etc. for the Mini.
Is anyone doing this, and if so, what do you think of using the Mini this way? Does it work well, and what are the pros and cons of doing this?
Thanks,
Ilya Smirnov

My experience with my Belkin KVM is also good, with the exception of one thing. I can't switch back to the Mini once I've switched to the PC. I have to unplug the PS2/USB adapter from the Mini and THEN do Scroll Lock-Scroll Lock 2. The KVM then switches, and I can plug back in. Everything works fine after that. It gets cumbersome though if you want to switch seamlessly between the two.
I only use the KVM for the KM part these days since my monitor (Samsung 930b 19" LCD) is able to switch between DVI and VGA by itself. And since I'm using the Windows box mostly for gaming these days, I use the DVI with the PC and the VGA with the Mac. The KVM was able to handle it without any distortion when I ran VGA on both of them. To the best of my knowledge, there isn't a cost-effective DVI KVM switch out there yet. I could be wrong.

Problems Usingt External VGA Monitor Through KVM Switch

I have my ThinkPad x201 connected to a KVM switch along with three other machines. The KVM is attached to a monitor with a resolution of 1920x1200.
Does the ThinkPad have to be rebooted with the KVM switch attached to the VGA port and with the switch set to the THnkPad?
I plug in the VGA connector with the KVM switch set to the ThinkPad. I then press fn-F7 and get four choses: Computer Only, Duplicate, Extend and Projector Only. I only want to display on the external monitor but Projector Only does not seem to be the correct choice although it does switch to the monitor it also puts up a message box saying the projector was not found. When I go to change the resolution I am offen limited to 1680 x 1050. Other times I can set it to 1900 x 1200.
When I switch the KVM to another machine I hear a tone from the ThinkPad that indicates something has changed. Then when I switch the KVM back to the ThinkPad I briefly see the display on the monitor at a lower resolution and then the monitor goes dark and the ThinkPad screen lights up.
I have also tried Extend mode with the output set to go only to the monitor. Again, if I switch the KVM away from the ThinkPad I hear a tone from the ThinkPad. When I switch the KVM back to the ThinkPad I again briefly see the display on the monitor at a lower resoulution and the the monitor goes blank and the ThinkPad's display lights up.
Is there a way around this behavior that will stop the ThinkPad from switching its output or can an external monitor only be used if it is directly connected to the ThinkPad?

I am also having the same problem with a ThinkPad T420s and a Trendnet TK-409 KVM. This KVM has worked for so many other laptops and desktops, I find it difficult to believe the ThinkPad would not work with a KVM - particularly this one. Any suggestions and help would be highly appreciated. Thank you.

Using iMac with KVM switch

Hello --
Can someone tell me if I purchased a new iMac with either the corded or cordless keyboard, could I hook up the keyboard, mouse, and monitor to a KVM switch and use the keyboard, mouse, and monitor with a PC? The KVM switch uses USB for the keyboard/mouse input.
I have to use the PC for work, but I don't want two keyboards, mice, and monitors on the desk, if anyone's curious why I'd want to do this.
Thanks!

Future iMac Mac OS X (10.4.4)

Someone correct me if I'm wrong... (I'm sure they will!)... but I don't believe the iMac can display a video signal input from another source (pc). It certainly can output to a second monitor, but that won't solve the space problem posed by two monitors on your desktop.

New Apple Keyboard for Dual G5 with KVM Switcher

Hi Everyone,
I have a Dual Mac G5 and a Dual Mac G4 with a Belkin KVM Switcher, so they are able to both share one monitor. I am not sure of the model number of the Switcher, but I bought it because it was recommended by Apple. It has worked flawlessly since I installed it over a year ago.
My problem is this. I plugged the new Mac keyboard into the G5, where the old one was. When I did this, the Switcher just kept switching back and forth, on and off, and just was not behaving.
Is there some software out there that I have to install that will enable me to plug in the new Mac keyboard without any problems with the KVM Switcher?
Thank you for reading this. I would sincerely appreciate any help. Best Regards, Luke 77

Just make F5 as your Dashboard...
System Preferences---> Keyboard---> Shortcuts---> Mission Control---> (check mark Show Dashboard)---> Double click the current state (could be F12). When highlighted, hit the actual key "F5".
From then on, you should be able to hit "F5" and it'll show the Dashboard for you.
I believe there are at least two Apple Wireless keyboard out there. The one that I am on right now shows 6 squares on the F4 key. The other has the dial face on the F4 key. This one also has brightness control for the backlighting on the keyboard, or rather the built-in keyboard of a Mac Book (Air and Pro). Which are on the F5 and F6 keys. Why Apple did that, I have no idea.
You could also use a Hot Corner to open the Dashboard. For instance use the upper left for it.
System Preferences---> Mission Control---> Hot Corners (lower left of the window)---> Select the upper left and scroll to Dashboard.
I personally like to have the Dashboard "fly" over my current screen/desktop. So I unchecked "Show Dashboard a Space."

I've lost OpenGL support with KVM switch. Help!

I have a Win7 64 machine and an XP machine at work. I installed an Iomega KVM switch to use the same monitor/keyboard/mouse with both computers. Problem is, once I installed the KVM, Photoshop can't detect my video card, so I lose OpenGL support. Very irritating. Anyone had this problem and/or know of a solution? Thanks!

Did you reboot Windows after plugging the monitor into the computer?
On another note, it's possible a recent video driver update changed the behavior. Photoshop queries the OpenGL system for its capabilities, and if something's gotten broken Photoshop might not allow the OpenGL operations. What video card do you have?
There is a workaround you can try - a registry tweak - that will instruct Photoshop to use OpenGL calls anyway:
Go to this site: http://www.adobe.com/support/downloads/detail.jsp?ftpID=4056
Download the file and extract AllowOldGPUS_ON.reg. You don't say which version of Photoshop you're using, but if it's CS4 the file is good to use as is. If CS5 then you'll need to edit the file with a text editor to change 11.0 to 12.0. Make sure you're an Administrator and double click the file to enter it into your registry.

How do I connect 2 external monitors with full HD to my MacBook Pro?

I would like to connect up my 2 external monitors to my MacBook Pro. But I want to have full HD resolution. I want to have the desktop stretched so I don't want mirror displays. What is the best way to accomplish this? Is there an adapter that I should use?

Thanks for the reply. Haven't gotten anything as yet. Just that I burned out my older PowerBook using it as a primary screen w/ a secondary 20" monitor. Would be nice if the MacBooks could be used as a CPU only, connect 2 different monitors, and use the LCD screen when portability is needed. But I suppose that is why Apple makes different types of computers. I know I can rig the video SCSI cable to bypass to LCD screen and use the other built-in monitor. But there goes the warentee and any kind of AppleCare... not that I have ever used it, (until a day after it has expired!)
But thanks for the feedback. Your reply is what I expected. Being that I am a mercenary graphic designer and need to be able to work whenever, and where-ever I need to, the MacPro is not my hardware of choice. As well, I don't have $4000 in my budget. But man do those machines rock! Just think of what NASA could have done with one of those in 1969 when we were going to the moon! But now that the U.S. has decided that manned space travel and even scientific space exploration is not worthy of having a budget, the MacPros are religated to creating new episodes of Jersey Shores!
Thanks again for your feedback!

Connecting two Acer monitors with VGA and DVI output to my Macbook Pro (mid 2010)

Hi All,
I need to connect 2 Acer monitors that have both VGA and DVI ports to my MacBook Pro. What's the best way to do that?
Thanks for your help!

hey! Thats normal for notebook! That actually happens to almost all of us - as there are a small fraction of people with two and more thunderbolt displays or with newest rMBP and external multi-monitor setup.

Connect 2 externa monitors with different resolutions?

Is it possible to oonnect 2 external monitors, with different resolutions to a mbp pro?
I've read some about the "matrox solution", but that one requires that the monitors uses the same resolution.
And, just to be clear, I don't want to just duplicate the screens, one should be primary.

You may want to phone OWC and ask whether what you want to do is possible if one monitor is connected to the mini-Displayport and the other is connected to a USB port using this adapter:
http://eshop.macsales.com/item/Other%20World%20Computing/VIDU2DVIA/
Note that the OWC adapter, like most USB video adapters I've seen advertised, is limited to a maximum resolution of 1600 x 1200, so you won't want to use it with a monitor whose native resolution is higher than that.

Connecting a regular Monitor with DVI

I'm wondering if I can connect a pc-monitor to the apple TV using a HDMI-DVI cable?
Instead of using a TV I want to use a pc-monitor with DVI input.
Is this possible or do I have to connect really a TV?

Welcome to the  Discussion Forums.
There would be a couple of issues to overcome. One is already mentioned by JG, HDCP is often not supported by DVI, you would need to check. Then there's a resolution issue the GPU of the tv may not support the native resolution of a large monitor, also your picture may or may not fill the screen and WS tv is 16:9, WS monitors are typically 16:10. Finally DVI doesn't carry audio so you would need to take care of audio in another way.
It's not impossible, there are those that use them with the tv, but you would need to check your particular monitor would work.

Closed lid, connected to external monitor with no image...

So I followed the directions on Apple support regarding setting up a Macbook Pro (Early 2008) to an external monitor. I'm using a Gateway FPD2275w (if that helps) connected to the DVI-VGA adapter, or whatever Apple calls it. I'm using a Bluetooth mouse and keyboard and have set the option to wake the Mac from sleep with them. I've set the display to mirror, though it doesn't seem to matter what I set that option to. WHen I close the lid the Mac goes to sleep and the external display goes to sleep as well, but when typing on the keyboard it shows on the screen, when I open it up again. Any thoughts?

You must also have an external USB or BlueTooth keyboard connected, not just a display. Alternatively, you can try the third-party utility InsomniaX - VersionTracker or MacUpdate.
