IMac connected to tv as dual display

I just updated to lion today and whenever I try to put movies in full screen on my computer it pushes them back to the monitor. It never did this prior to the update. Is there a setting or something I have to change?

Either drag the screen across or you can go to System Preferences -> Displays -> Arrangements and enabled Mirror Displays.

IMac G5 (iSight) wont do dual display? Are you kidding me!

Why in the world did Apple even make a computer that won't do dual display. This is probably one of the first let downs I have experienced with Apple. I just purchased the iMac G5 to use primarily for presentation and need dual screen capabilities. I should be more clear on the specs page that the "all new" iMac DOES NOT DO DUAL DISPLAY. I am thinking of returning the iMac and going another direction (pc) and don't want to, but may not have a choice, unless someone has a fix for my problem.

I understand the risks of hacker-ware, and certainly don't want to void my warranty. But this begs the question: If a hacker can figure out something that usually works, can't Apple fairly easily come up with an official iMac G5 expansion that will always work and that won't void the warranty? Please, Cupertino, Please! I've subscribed to this topic string in hopes of hearing a happy ending.

Imac 27" Intel Core 7 CPU. Screen goes black and will not respond except with a push of power button. Second monitor connected via displayport continues to display fine. Apply Store did full hardware scan and all is fine. Did clean wipe from Mavrick back

Imac 27" Intel Core7 CPU 16 Gig RAM. Screen goes black and will not respond except with a push of power button. Second monitor connected via displayport continues to display fine. Apply Store did full hardware diagnostic and all is fine. Did clean wipe from Mavrick back to Mountain Lion but problem remains. Apple Store can do no more.

I did some more digging, it appears to be a backlight problem only. I can see the screen very dimly if I use a bright flashlight in a very dark room. It also seems to run ok if the brightness is turned down a LOT.
So I'm thinking this is a LED driver board issue or the display itself. I'll open it up and check the connection between the two and see if I can get any more clues. At least I can use it somewhat now by dimming the display significantly...

IMac Dual-display colour profiling on second LG monitor

Hey guys,
I just purchased a second screen for my imac to use dual display, im a graphic designer and really need the space. What is the easiest and best way of mirroring the colour setting of the iMac to my second screen without the use of 3rd party colour calibrating software?

Hi macboydesign
Welcome to Apple Discussions
Lots of practice!
Not included in the current lists there were a dozen other DYI profiles between the iMac and LG that were so bad, I had to delete them.
The following article is dated, but has some great tips and info:
http://www.computer-darkroom.com/colorsync-display/colorsync_1.htm
Oh' almost forgot to mention, uncheck that box "Show profiles for this display only" and try some of those sRGB and RGB profiles to see if you can get closer that away.

An iMac 20" with an 20" Cinema Display as second screen in dual

I'm planning to buy an iMac 20" but I want to be sure of something before. I want to know if the screen of an iMac 20" and an 20" Cinema Display put together will be exactly at the same position. I search a lot online to have a picture of this but I only found some 17" iMac put together of an 20" Cinema Display. If someone can answer and/or give me a picture of this that would be really nice.
Intel PentiumD 830 3Ghz, 2Gb Ram, 7800GTX, 2x36gb Sata WD Raptor 10k, 2x19" LG T910BU Display Windows XP Pro

Here is a quote from the user reviews section of Amazon.com, about the new 20 inch Imac core duo:
Video out - The new iMac, for the first time ever, features a Mini-DVI output. This allows, with adapters, the ability to connect the iMac to a DVI display, a television via composite or S-video, or an analog display via VGA. I have my new iMac Core Duo connected to my 20-inch Apple Cinema Display, and it works perfect! A nice feature. This allows for screen-spanning, so I can take advantage of both screens.

IMac connecting to N channel on a dual band router but only at 54mps

I have an iMac late 2009 model connected wireless to a dual band Netgear WNDR3300 router. My problem is it only connects at 54mps on the N channel and that is with the router placed 2 meters from the computer. My PC laptop similarly placed connects at 270mps no problem. When I option click on the Airport Utility in the menu bar it tells me I'm in 802.11n mode on channel 149(5ghz). When I first got the iMac it connected easily at 270mps. So something has happened. Has anyone had a similar problem?

I had a similar problem with a NetGear DualBand DGND3300v2, the issue in the end was security.
I was initially trying to use WPA-PSK and getting this exact same issue, with my Mac, stuck at 54Mbps on the 5GHz band, disabling the security allowed me to connect at 'up to 270' but obviously not secure, so moving up the security options tried WEP, this also allowed 'up to 270'. WPA-PSK was no go, so I went to and am using WPA2-PSK and it works fine, sometimes I get a connection of 300Mbps.
So give it a try, let me know of it works for you...

Dual display help for a recently converted mac user

I have a 24" Intel IMac and I wanted to set up dual displays. I may have jumped the gun a little because I didn't do much homework but I found a big cheap monitor at Best Buy which is an HP w2338. I bought that and the mini-DVI to VGA adapter. I hooked everything up and both monitors work but I have a couple small issues that I can't seem to find how to fix. First, I have about a 1.5 inch strip along the left side of my hp monitor that isn't used at all. It is just a black strip that taunts me. When I drag things from my IMac to my HP it drags fine, but it just acts like the monitor is smaller than it is. The resolution on my IMac is set to 1680x1050 and on my HP it is 1920x1080. Second, I have very faint vertical stripes in my new HP monitor. They can be seen the best in the grey parts of my windows. Any help with either issue would be greatly appreciated.

On your 24-inch iMac's screen, the native resolution is 1920x1200. You can use a lower resolution, but the display will seem a bit fuzzy (the pixels are being approximated). So you should use 1920x1200 on the iMac's screen, unless you have a good reason to use something else.
On the HP display, it sounds like the native resolution is 1920x1080. That's the resolution of an HDTV, so it should work. However, when you connect an HDTV, it connects with a digital connection, HDMI. So I think it will work if you connect it HDMI. If that monitor happens to have DVI, use DVI.
If it only has VGA and HDMI, there was a recent topic that was very similar (same display I think). Is your iMac the older model (not the brand new 2009 model) with a Mini-DVI port? If so, take a read there to see if the information is applicable to your situation.
http://discussions.apple.com/message.jspa?messageID=9247482
Now, if that display you have is different, and it has a DVI connector, please post back.

How to Dual Display with Dell U2711

Hi,
I am looking to connect my iMac (late 2013) to a Dell U2711 in a dual display configuration. I'd like to be able to use all 2560x1440 pixels of the Dell.
the Dell has DVI-D (dual channel), Displayport (not mini displayport), HDMI and VGA.
which port will give me the cleanest picture and best performance and what cable do I need to buy ? (obviously thunderbolt to something...)
thanks !

Or if I need to use GPT or MBR?
Your disk is already partitionned so you don’t have to choose between GPT or MBR, the choice is already made.
You don’t partition “C:”, that is the name of a Windows partition. You partition a drive.
Grub or syslinux, use whatever the beginners guide tells you to. Personally I think syslinux is simpler which is why I’m using it (but I’m not dual-booting, if that matters).
You’re not saying what your problem is with partitionning, so it’s hard to help.
Thanks for getting back to me, I'm not sure if I just create one large partition for Archlinux or if I have to create multiple? Where I'm also confused is with the Creating Filesystems part of the guide. I don't understand how I'd do this in Windows, or what /dev/sda1 is referring to.
As for the bootloader part, the Beginner's Guide gives you a choice between syslinux and grub, what I'm not sure about is which to use considering I'm dualbooting. How it will affect my windows bootloader, do I disregard that and use GRUB now? I'm unclear on how that works.
I'm also aware I need to disable Secure Boot, I just searched my BIOS options and couldn't find anything remotely relating to that, so I'm assuming it's not an issue since this computer was originally on Windows 7 anyway?
Thanks again, Expi.

How I connect a 27 " Mini DisplayPort Display to a Mac Pro 2006?

Dear All,
I need to know if I can connect a 27" Mini DisplayPort Display to Mac Pro 2006
Thanks a lot in advance
Subalv

You can certainly do that, the Apple Online store sells it for US$150.
http://store.apple.com/us/product/H3938LL/A?fnode=MTY1NDA5OQ&s=topSellers
I have not tested it. It is certainly good to know it exists. I hate paying the premium for "leading edge" equipment, so I am writing from my 2009 Mac Pro with used Apple 30 inch Cimena display.
If I were to pay what that new display costs, I would buy a new display card to drive it directly. My recommendation is to upgrade your diplay card for US$100 more (than the cost of the adapter) and get a card capable of Dual-Link DVI AND two Mini Displayports.

I am currently running a mac mini mid 2011. As I've understood (according to the below statement). Am I only able to use 2 secreen with 1920x1200 or could I use one screen with 2560x1600 and one with 1920x1200. I do NOT want mirroring, only dual displays.
I am going to connect the screens in the following way:
1x mini-dvi - HDMI to one screen.
1x HDMI - HDMI to the other screen.

According to the copy&paste from wikipedia, HDMI should support higher resolution than 1920x1200. So the question is, does it aupport that on the mid 2011 mac mini. It says in the specifications
"Mac mini is designed to work with HDMI devices that comply with versions 1.0, 1.1, 1.2, 1.2a, 1.3, 1.3a, and 1.4 of the HDMI specification."
That should mean it should be able to support it, but I don't know : <

How do i use my imac 21.5" 2011 as a display for my macbook pro late 2011, through thunderbolt cable ? I have tried and it doesnt seem to work, neither does target disk mode.
Could it be a borked cable ? I just bought it new from the store today, i have updated both imac and macbook pro to latest thunderbolt firmware and updates. Both 10.7.3.

You are correct, here is what Apple Says:
http://support.apple.com/kb/TS3775
I was able to find these instructions, however they referr to 2009-2011 27" iMacs. I think it's the same, if it's not then contact Apple directly for instructions. If either of the machines is less than 90 days old or covered by AppleCare then call AppleCare tomorrow for help, they should be able to easily answer this for you. You will find the number in your manual or you can use the AppleCare Contact Info link.
Your iMac should automatically recognize the presence of a digital video signal at the Mini DisplayPort and enter Target Display Mode.
If your iMac does not automatically enter Target Display Mode, press command + F2 to manually enter Target Display Mode.

Dual display color and other related issues...

I have posted this on painter forums, though some of the issues coming together here are directly related to issues w/ Snow Leopard and dual displays. Thought I would try here....
This is so bizarre. When I ever I run P11(I think this is going on in P10 too?) w/ the OS X (snow leopard, 10.6.2 on quad core Intel Xeon Mac Pro, 10 GB of RAM) menu bar on my Eizo(making it the main display), and the Apple Cinema display left as the #2 monitor, I get very annoying brush cursor artifcats left randomly on the Eizo screen after strokes. One cannot predict when the cursor will leave it's gray "marks", but it will do it, sometimes 5 strokes in a row, sometimes after 15 strokes or so? If I move my brush back over them, or change the image percantage view, they vanish, obviously new ones coming back, as I work.
However I put the OS menu bar on the AC display, yet work back on the Eizo, this does NOT happen. No cursor artifacts. Well, at least I can summon the issue
The reason I am doing this is Snow Leopard has bad color issues w/ dual displays (well documented, much to Photoshop CS4 users frustrations, and mine). Apple needs to fix it... but for me to see the right color on the Eizo(this is my main color and superior display), it needs to be the main monitor(menu bar) in 10.6.2.
So, you can see my trap - Accurate color, or annoying cursor artifacts left on the screen (sorry, it really bugs me as I work) as I work in Painter.
Attempted fixes: Trashed all of Painter's prefs, all of Wacom's Intuos 4(latest driver) prefs and software, switched plug ins on the back of the mac for the displays(lots of restarts), ran cache cleaning Cocktail and DiskWarrior, etc. -- no change, as I can duplicate the issue w/ the above set up. A sidebar or maybe be very related note: I have an iMac w/ max amount of ram (model not very old -- maybe 1 or 2 old) and I have had a long standing issue working on the iMacs we have had w/ this brush cursor artifact problem (in Leopard and Snow Leopard). I am on one monitor w/ the iMac, so you know here the menu bar is...hmmmmmmmm.....?
Thanks!, T

Possible to do dual display with a mini?

I have an early 2008 Mac mini (Intel) - with the standard DVI connector; using the supplied DVI/VGA adapter to connect to an LCD monitor.
I'm just wondering if it is possible to use two displays with this model and if so, how do I connect the second monitor?

Several ways of doing it in this thread:
http://discussions.apple.com/thread.jspa?messageID=8335705&#8335705
If you want to go the usb route, see also:
http://eshop.macsales.com/item/Other%20World%20Computing/VIDU2DVIA/
Be sure to examine the limitations of each method.
(I'd also consider that your 2008 Mini likely has substantial resale value and that you might prefer getting a 2009 Mini which natively supports dual displays.)

Dual Display - help with Cinema Display for MacBook Pro where MB won't detect displays.

I just got a Cinema Display (a1081 20") ("CD") off eBay to use as a dual screen with my Macbook Pro OS X 10.6.8 ("MB"). However, I can't get MB to recognize CD! I've tried power cycling both the MB and the CD with and without USB cord connected. MB won't recognize CD display in any situation. However, it is recognized in some capacity although I can't use dual display because the CD power button triggers MB to ask me if I want to restart, shutdown, or cancel.
Any help is appreciated!!

Have you tried smc and pram resets?
Try Detect Displays in the Displays preference pane.
Does the Displays preference pane Arrangement show two screens? If so do click gather windows and check the resolution setting of the new screen.
