Imac g4 vga adapter (mirroring on different monitor)

Hi,
I am wondering what it means to mirror an imac g4. I am going to get a vga adapter ounce I get the imac and use a second 19" monitor. Also, what is the vga display output resolution with it.
Thanks

The resolution of the external will match that of the internal in mirroring. The greatest benefit is to set the built-in to its greatest setting that might be too small on the 15" screen, but should look good on a conventional 17" or larger display.
Again, you will be disappointed with the image on a wide-screen monitor. This is a great opportunity to get more life from an older, working conventional 4:3 ratio monitor that is no longer useful on new computers that support widescreen displays.
The best thing to do is look at the list of res options you have today in System Preferences > Displays. You can tell the aspect ratio by dividing the res width by the res height. Example
1024 by 768 res option:
1024 ÷ 768 = 1.3333
That's the same as 4÷3, thus a 4:3 aspect ratio.
on the other hand, a widescreen res of 1440 by 900 does this:
1440 ÷ 900 = 1.6
which is the same as 16:10. The newer 16:9 ratios would return 1.7777 in the division process.
So look at the res option you have and see if any support something that gives a ratio that divides to give greater than 1.3333. If you find one (unlikely on that vintage iMac) you can go widescreen in mirroring.
I have also heard of some programs from another post I saw that would let you increase the resolution of the second monitor. Are they any good?
I've also heard of then but haven't used one. Maybe someone else can comment.

I have a imac 2308. where can I find a thunderbolt to VGA adapter to add additional monitors

I am trying to attempt to add two additional dell monitors (vga) to my EMC2308 imac. I only have one thunderbolt port and have not had luck finding a thunderbolt to vga adapter. Any ideas?

A notable peculiarity of Thunderbolt is that it uses exactly the same connector as Mini Display Port, and that's not all. The Thunderbolt connector also carries Mini Display Port video signals. That means you can plug a Mini Display Port video cable/adapter in to a Thunderbolt connector and your monitor will work.
If you plan to do other things with your Thunderbolt connector and don't want it wasted on a monitor, you can also choose an HDMI --> DVI adapter, which for your purposes will be functionally equivalent.
You can even use both at the same time.

Will a Mini-Displayport to VGA adapter work with new macbook pro 2011

I was thinking of getting a mini-displayport to vga adapter for my external monitor I wanted to hook up but I wasnt quite sure whether it would work as my macbook pro has the new thunderbolt port, I was confused if the new port would only work with the thunderbolt displays. Could anyone help me as I'm not too sure what will work.

I tried the Apple miniDisplayport to VGA in a Thunderbolt MBP and iMac and they both worked. Same for the Apple miniDIsplayport to DVI.

VGA adapter with iPad 3 creates yellow image on VD

An apple VGA adapter works fine with iPad2, but with iPad3 the image is too yellow.
I tried on two different iPad3. I repeat there is no problem with iPad2.
Is there a new generation of VGA adapters for iPad3 or is this a defective unit?
Regards

I know this thread isnt that recent but the answer can be found when you look at the VGA adapter product page mention in an earlier post:
"The Apple VGA Adapter mirrors exactly what you see on iPad 2 so that everyone in the room can enjoy it.
The Apple VGA Adapter supports video out (only) for iPad, iPhone 4, or iPod touch (4th generation)."
So there you have it - only video out is supported on the original iPad / iPhone 4 / iPad Touch.

No image on screen using Mini DisplayPort to VGA Adapter

Received mini today. After unboxing, read through the packet. Then began to hook everything up as directed. I used a Mini DisplayPort to VGA Adapter to connect the monitor from our now dead desktop to the mini. After double checking all connections, I hit the power button. I immediately heard the apple chime. Then the monitor showed the grey apple start up screen. Suddenly the monitor went black and said it was going into sleep mode. I can't get it out of sleep mode when connected to the mini. It is NOT the monitor or the adapter. I plugged the monitor straight into a netbook and it worked. Then, I plugged the monitor using the adapter into my MacBook Pro and also got it to work that way. So I tried replugging the adapter into the mini. Still can't get an image on the screen. I can't complete set up or use mini because I can't get an image. Any suggestions or ideas? I will call apple in the morning if I can't figure it out tonight. But I'm hoping someone can give me suggestions. Thanks for your help!

I had the same issue when I bought my mac mini last week apart from I wasn't even getting the initial grey screen. I went back to the Apple shop and they gave me another mini and fired it up in the shop using the adaptor on an old VGA monitor. It worked perfectly.
When I got home I set it all up again and still had the same issue. I nearly threw out a couple of monitors as I thought they were broken.
However, had a look around the web and found this suggestion:
Shut down the mac and disconnect the adaptor from it. Now fire the mac up and let it boot up FULLY. Once it has had a chance to boot up fully, only then plug the adaptor in.
Worked for me and I haven't had the issue since (touch wood). Hope this helps.

Connection to external display does not work under windows bootcamp, with a thunderbolt to vga adapter.

Hello guys, after searching a lot in the forum for an answer to this, I could not find a solution so this is the reason for this post.
I have a Macbook Pro (early 2011 I think) running MacOSX Lion and I have installed Windows 7 64-bit through bootcamp (version 4.0).
Everything works fine except that I cannot connect my external display through my thunderbolt-vga adapter.
The external monitor shows only the boot screen of windows (the one with the windows logo) and then, when I get into the login page it goes blank.
After reading the forum, I have done several things in order to fix this problem such as:
Restarting the macbook with the thunderbolt device connected to it.
Updated to the latest ATI drivers through bootcamp.
Removed the graphics driver and re-install it again.
I have tried to identify the external monitor through windows 'screen resolution' tool (attached photo).
but still no luck.
Does anyone have any idea on what else I could do in order to fix this? By the way, I find it very frustrating that Apple does not have a stable solution to the problem with devices that are connected to the thunderbolt port.
Thank you in advance

Apple VGA Adapter, with iPad 1, OS 4.3 upgrade and Data Projector?

Hi,
Our school is testing a number of iPads, and I will be buying a iPad 2 on the 25th March. I would like to test my iPad 1 with the Apple VGA Adapter and my data projector in my classroom. (All Apps)
In the past the Apple VGA adapter did not mirror the apps, however the Apple site now has a link to mirror technology with the VGA Adapter.
I could buy the Apple Digital AV Adaptor (HDMI) but would then need to find a HDMI to VGA convertor to connect to my data projector.
I would love to show my students Garage Band on my projector, but need the correct cables.

Input signal out of range with HDMI to VGA adapter LE1901w

Hi!
Recently I acquired an LE1901w monitor to use as second screen. I'm trying to connect it to my Toshiba u925 using an HDMI to VGA adapter (because neither the monitor has a HDMI port nor the notebook has a VGA output).
I'm getting the message "input signal out of range" asking to change to 1440x920 @ 60Hz and it keeps showing until the monitor goes to sleep even when I change the settings as per requested.
I have an integrated Intel HD Graphics 4000 and i'm using the default Windows monitor drivers for Windows 8.1
Any comment will be helpful
Thanks

Hello @fbinim,
I understand that you are getting the message "Input Signal Out Of Range" and it is asking you to change to 1440x920 @ 60 Hz. I suspect this is a driver issue and you will need to ensure that your drivers are up to date on your computer. Just to be sure I would recommend if you could to move the HP LE1901W monitor to another computer and ensure that you do not have the problem there. If you do have it on another computer The issue you are experiencing appears to be a physical issue. Please call our technical support at 800-474-6836.

I am considering a Apple iMac but would be interested in adding a second monitor. Does it have to be an Apple monitor or can i add any monitor with a thunderbolt cable and DVI or vGA adapter?

I am considering a Apple iMac but would be interested in adding a second monitor. Does it have to be an Apple monitor or can i add any monitor with a thunderbolt cable and DVI or vGA adapter?

I found that the Thunderbolt input accepts the mini-DVI (in my case converter to VGA for a tutorial use monitor)
BUT, you have to really oush it in 'til it clicks. I thought it too loose until I tried it. works just fine!!
i get a solved for my own LOL

I have a 27" IMac. I want to add additional monitors to it. There is a vga slot for the first monitor. I would like to add a second monitor but there is not another via slot. Is there an adapter I can get for via to usb?

Here's the problem I am trying to research for you...
There does exist a way to add a second monitor via USB:
USB 2.0 to HDMI Audio Video 1080P Adapter for Windows and Macbook
It's the only device I know of that can do that. The problem is that it wants a HDMI connection. So that means a HDMI-to-VGA adapter or converter needs to be found (not VGA-to-HDMI, those are easier to find).
Interesting article realted to this:
Hdmi to vga adapter
Maybe somthing like this converter will work.

Hi Josh,
To start, it is considered extremely impolite to type in all capital letters as you have done. Please use all lower case, or preferably properly capitalised text, in future.
With regards to the problem you're having.. the reason you only see the desktop background is due to screen spanning. If you want the external display to display the same thing as the internal display, go to the displays system preferences pane, and check the box that says "Mirroring"
The color problem is probably due to a loose connection somewhere, either between the iMac and its adaptor, the adaptor and the cable to the projector, or between the projector and the cable plugging into it. If you're still having problems, try different adaptor cables, or try plugging it into a different monitor to try to work out which one is causing a problem.
Good luck

Mini Display Port to VGA adapter + Monitor Eizo s2231W = CRASH

I purchased a new macbook pro last month with 2 adapters, one for VGA the other for DVI. I'm having some trouble with the Mini-DVI to VGA adapter. The Mini Display Port to DVI adapter works well.
When I attach the VGA adapter to the monitor it works well for a couple of minutes, then I dont know why my MBP crashes and I can see a purple or white screen. The crash is really a crash... cauz I cant do anything. My mac is frozen and the only way to resuscitate him is to keep pressed the power button for a while till it turns off, and then turn it on again.
You can say... why do you need the VGA if the DVI works...
the problem is that I'm probably supposed to use it one day attached to a projector because of a presentation at university.
So I dont wanna see my new macbook pro freezing in front of my professor.
please help.
EDIT:
adding some precious information
My hardware configuration as regard the graphic chipset is
NVIDIA GeForce 320M
The resolution of the external monitor is 1620x1080
I'M NOT using the mirroring ( but the desktop extension)

I had the exact same problem. It actually escalated from there and it would crash at the startup screen (the white one with the apple and the spinning gear). The only way I was able to fix this was to reformat the entire computer. I was lucky enough to have backed up all my data when it first started crashing. I've only reformatted yesterday and things seem fine for now. I don't know what caused it, or how to fix the problem any other way.

Connect two external monitors to mini DP(using a mini DP to VGA adapter) and the VGA out at once

I am trying to connect two external monitors to mini DP(using a mini DP to VGA adapter) and the VGA out at once. Windows recognize both monitors as well. But it dowsn't let me use all three monitors at once(see the below image). In the dropdown, it lists all three monitors. Problem is there are two active displays I can select.

The GPU(s) in your T400 (and most other laptop brands) will support two different displays concurrently. If you want to support more than two different displays concurrently, you will need another GPU external to the T400.
Generally, if you want to use two external displays on a T400 you will nee dto use a docking station.
I have read messages on various fora on this topic and know that there are a number of ways of doing this, but as I have never had a need to do this myself I can't tell you how to go about it.
