Can't Get Dual Monitors to Work

My main monitor is connected via DVI and my second monitor is using a VGA cable. I've tried just about everything and can't get the 2nd monitor to display.
When using AMD Catalyst Control Center, the "Detect Displays" section can only find my main monitor.
When using Window's "Screen Resolution" settings, the 2nd monitor is found, but it will not allow me to set it to "Extend these displays" in the Multiple Displays dropdown. The only option that works is "Show desktop on on 1", which ofcourse, only allows me to use the main monitor. I've attached a screenshot below.
Please help! I bought this computer because it allowed for 1-3 monitors and if I can't even get 2 working, I'll have to return it.
Thanks!

T410 with 4337 docking station - can't get dual monitors to work

running win 7, unit has the Intel graphics. I can't figure out how to get any display to work off the docking station, VGA or digital. Discovery does not seem to pick up the external monitors.

Got the latest BIOS and graphics drivers?

How can I get Activity Monitor to work?

I've searched the discussions to no avail, so I have this question: how can I get Activity Monitor to work? It launches and its window opens but then the spinning beachball appears. I've checked the Console and it shows that the Activity Monitor is attempting to fully launch but then it "exits" and then it tries to fully start up again, goes into an infinite loop or something. Issued a "force quit" succesfully. I've deleted the Activity Monitor's .plist, no joy. What to do? Thanks!
I'm running 10.6.8 on a MacBook Pro (late 2011)

I wish I could be more positive but I have no experience of MacBook Pros and whether their demands on the system differ from my simple iMac. If you have the time to scour through 'More like this' ( to the right of your initial post) and the links within it, you may find leads.
I also found this thread via Google which in parts seems to echo your troubles. I hope it helps; thank you for the star.

Seeking a clear description of getting dual monitors to work

I've spent a long while researching the issue of getting dual monitors to work on a new mac mini - which I will be purchasing as soon as I figure this one out! But I am bamboozled by references to the various types of connections and ports. If anyone has the patience to explain this really simply and clearly, I'd be very grateful.
Interestingly, the Apple guy on the phone today told me it isn't possible - it's either/or for the display connections. But clearly it IS possible, because there is so much discussion about it here...
Here's where I confess my technical limitations, and say that I am confused about what I need (to purchase, presumably) to get my two existing monitors to work with the new mini.
They are presently connected to my PC (soon to be ceremonially consigned... etc) with cables which have regular D-sub connectors at each end. This means they are vga, right? There is no digital connector on either monitor.
So I am trying to figure out
a) is it possible to use these two monitors in a dual display setup with a mac mini? If so:
b) How?! And then;
c) what leads and/or connectors do I need to buy in order to connect them up?
Thanks for being here, I hope for some patient guidance.
Jeff

Welcome to the Apple Discussions!
An '09 Mac mini has two video out pots on the rear; a mini-DVI port and a mini-DisplayPort. The Mac mini comes with a mini-DVI to DVI-D adapter. If you use what came in the box with the mini, you need a DVI-D to VGA cable to connect one of your monitors. Otherwise you need a mini-DVI to VGA adapter and a VGA to VGA cable for one monitor. For the other monitor you need a mini-DisplayPort to VGA adapter and a VGA to VGA cable.

Can't get two monitors to work on my G4 533 Dual

Hello,
Does anyone know how I can get 2 monitors to work on my G4 533Dual. if I plug them both in at the same time the clear monitor goes out (Apple Studio Disply 17 inch transparent monitor). If I plug it in first then add the 17inch Apple ColorSync display the Studio display wont work. I have restarted and tried all different things the ports all work as do the monitors just not at the same time. I want to be able to see different things on both monitors. I also have a 733 with the same GeForce2 MX card so swaping them wont help. Can anyone tell me what I need. thanks.

The other monitor is the 17 inch apple studio display (transparent)
Thanks

If you can find a used one. That is the only dual card Apple was selling at the time. There a other choices now, from adding a PCI card, to replacing your current card with a dual. I'm not sure of the AGP speed of your machine, so can't recommend a specific card, but when you do buy one, insist on a money back guarantee that it will work with your machine. Some cards don't work with all the machines the claim to be compatible with.

Can't get external monitor to work

I've used a Mac laptop for the last 8 years, finally decided to get an external monitor for home use.
I purchased a 25" Hanns-G HZ251. It's not working as I would expect it to work. I've got a standard DVI connection on my older MacBook Pro so I'm connecting via a DVI to DVI cable.
The only way I can get the monitor to display what is actually on my laptop is to have my laptop open and mirroring turned on. I thought I could have my laptop shut and the monitor would still work when connected, but when I shut my laptop it just goes black.
If I leave my laptop open but turn mirroring off, I get the generic purple Mac desktop, not my desktop.
What am I doing wrong?
There's an install CD that comes with it, but that only runs on a Windows machine. I appreciate any advice, I'm fairly technically handy but this is my first foray into using external monitors, so I'm definitely struggling to figure this out. Thanks.

Yes, it's connected to the power adaptor and I have an external trackball and keyboard.
You will have to keep them both open and play around with monitor settings until you get them both working. Keep doing "Gather windows" in System Preferences to get the display preferences window for the 2nd monitor and change it each time it doesn't display anything.
I don't know what it means "you will have to set it".
You have to set the desktop for the additional screen. Once you get closed clamshell to work, the external monitor will be your primary screen and you won't have to worry about it.

Can't get 2 monitors to work at the same time G4 533

Hello all,
I have a G4 533 Dual with the stock card in it I think it is a nvidia GeForce 2MX I have a 17 inch clear monitor It is the one that matched it new. I also have a old apple 17 inch display this is the old tan one with the colored apple on the front( I have an adapter to plug this one in). The video card has 2 ports and both monitors will work in their port but if I plug them both in at the same time the clear monitor goes out. If I plug it in first then add the older one the older one wont work. I have restarted and tried all different things the ports all work as do the monitors just not at the same time. I want to be able to see differnt things on both monitors. I also have a 733 with the same 2mx card so swaping them wont help. Can anyone tell me what I need. thanks.

Hi Sarkis,
I note that this is now the subject of another thread that you started - it's better to stick with one thread per subject otherwise there's "double handling" involved in answering your issue.
For what it's worth, the older (none core image) cards that will do extended desktop are:
Mac Radeon ATI 8500
Mac Radeon ATI 9000
Mac GeForce4 Ti
As a rule of thumb, a card with 64 mB or more will generally be able to do extended desktops.
If you want core image support, then any card later than the ATI Radeon 9600 will do, with the ATI 9800 probably being the card of choice.
This has been posted your other thread as well.
Cheers!

Can't get dual monitors to come back up when docking. T500 with mini dock & XP

I have a T500 with XP installed. I am using it docked into a mini dock attached to two 20inch Viewsonic monitors. One connected via VGA and the other DVI. I setup the dual monitors just fine. Anytime after I undock and boot up the laptop I can't get the dual monitors to automatically display. I have to go into the display properties and re set it up each time. Can anyone suggest any ideas?

When your T500 power-on , press F1 to log in BIOS, and change the option in >config>Display>Boot-Display-Device to Both or VGA, I suppose that it will reslove your problem.

I can not get my monitor to work!

Hello everyone. I have a first gen MacBook Pro 1.8 GHz with ATi graphics X1600. I can not get my external monitor to work. I have updated the drivers and installed the ATI catalyst control to no success. When I plug my monitor in, my laptop display immediately becomes monitor #2 and the external monitor will not wake up. I can not bring up any preferences or anything because everything is on the sleeping monitor. I have searched but haven't found a lot, maybe i'm just bad at searching which is possible. This is driving me nuts! Any help would be greatly appreciated!

Can't get 2nd Monitor to Work

I have a MacBook Pro 2.16 Core Duo. I also have a Dell LCD display, about 3 years old. I can connect the Dell monitor with a DVI cable, but the MacBook doesn't sense it.
My only clue is that on the MacBook, there are four pins right by the horizontal "blade" pin in the DVI output, but the Dell monitor, which is also DVI, does not have inputs for those four pins. I notice that some DVI cables have those four pins, and some don't.
Help!

Thanks for the help. I now understand DVI better, but that didn't solve teh issue.
I took my Mac and Dell monitor to the genius bar today. They confirmed that my Mac external port supports other monitors, but not this one. We plugged another Mac into the monitor and still nothing. SO either the Dell LCD monitor is not compatible with Mac, or there is some keystroke that must be made to sense the Dell that I haven't figured out. Was on the phone with Dell also - they suggested command-F2, but that didn't do anything.

How do i get dual monitors to work with bootcamp (windows 7)

i have a macbook pro intel core i7
using a VGA adapter for connection of the monitor
when i use the mac side the dual screens work perfectly, but when i use bootcamp with windows 7 the screen stays blank, i know it ver recognizes it because when i drag my mouse over to the right it goes out of the screen and then i have to drag for a while before its back on the mac screen, so it is being used but not being displayed. also when i first start up windows its shows the boot screen on the monitor aswel but then goes blank.

If you are talking about MS Windows then you need to launch either Boot Camp or run it in Virtualization app such as Parallels or VM Fusion. You also need a valid license of MS Windows.However if that is not what you mean then you must be much more specific. For example:
"I want to share some files between my PC running Windows 7 and my new iMac running 10.9.3, how do I go about that?"

Can't get video monitor to work

I inherited the JVC TM-A101G, but I can't seem to get a picture on it (well, I did once, but the next time I logged on it had disappeared again).
Here's my setup:
I use a Panasonic mini-DV camcorder as my "deck"
Firewire from the camcorder to the G4
Firewire from the G4 to a DAC 200 converter
S-video from the DAC200 to the JVC monitor
What do all those connections get me? A blank screen on the video monitor. Can anyone help?

Yeah, Final Cut Pro is REALLY confused as to what device to send or receive a signal.
Camera...or deck...or converter. ONE ONLY.

HT3258 Upgraded to Lion and now I can't get my monitor to work

I just upgraded to Lion and now I can't connect to my Dell monitor. I am using a MacAir. I have tried chaning the input. But that didn't work. Any suggestions?

That was a widely publicized fact, it is a good idea to always check compatibility before upgrading. Your options are to go back to SL or find another app.

Help... I can not get my microphone to work

Help.... I can NOT get my microphone to work with my Blaster X-Fi XtremeGamer Fatal1ty Professional card. When I plug it in and test it (in either Configure Speech Recoginition - Windows Vista / or in Counter-Strike Source, Test Microphone Button under the game options) both indicate that the system is not receiving any sound. However, both the speakers (5.1) and headphones work fine. I am using a Plantronics headset.
I am not sure what I am doing wrong. Below are my complete system specifications. Let me know what additional information you need, if any.
