IMac - Dual Screen Monitors. Windows issue

Hi,
I have an imac 27inc and a 27inc led samsung side by side.
I have connected the samsung to my imac and the dual screen works perfectly in the Mac operating system.
However.
When booting up in windows (using bootcamp) the samsung has black borders around the screen and is not displaying a full image ?
Is there a fix for this ?
I have connected the imac and the samsung through HDMI.
Cheers,

I sounds like Windows is not correctly reading the screen's capabilities. There should be something like a Control Panel to reset the screen resolution to the screen's best native resolution.
With CRT's there was a huge expanse of phosphor on the inside of the tube, and you could fudge the resolution quite a bit. With LCD, you have one "best" resolution, and if you don't hit it perfectly, you get fuzziness or black borders.

Dual Screens in Windows 7 (Boot Camp)

Hi,
I recently installed Windows 7 in bootcamp and I would like to use dual screens with my Mac Mini. Windows only recognies one of my monitors (the Mini-Display Port) and cannot find the Mini-DVI monitor. Am I missing a driver or something (I have installed the Windows Drivers off of the OS X CD Already)
Thanks in Advance!

mp4 is just a wrapper... doesn't tell, what's inside.
use a tool such as iMediaHUD

Dual Screen, missing windows ?

Hi there
I've got a second screen setup with my iMac and all is working well until the last OSX update. The issue mainly exists with both Thunderbird and Firefox (latest versions of each).
For example if Thunderbird is open and located on my secondary monitor - when I hit "write" to compose a new email the modal window doesn't appear. If I check Thunderbird > Window I can see I have a new mail message window yet can't get to it to compose a mail.
If I move Thunderbird to my iMac screen and do the same thing I see the new empty mail ready for me.
This function has worked ok in the past so I'm not sure whats changed ?
It's possible these windows could be minimised somewhere yet I can't find out how to resize/access them ??
Any suggestions ?
Thanks,

Dual L2206tm monitors - Windows 7 - Can both do touchscreen?

I have a custom-built desktop computer and I recently got two HP L2206tm monitors because they were on sale. My computer runs Windows 7 Ultimate 64-bit. I have both monitors plugged into USB ports on the desktop, but if I touch one of screen of one of them, the click or the scroll or whatever action happens on the other monitor. Is there a way, and if so, what is the easiest way to set up both monitors to be able to use the touchscreen feature? Is there any software to help make this process easier?

Swap 15" iMac flat screen monitor for 17" one?

My mom has 2 older G4 iMacs, the one with the hemispherical base. One of them has a 15" monitor (that's the one that works); the other iMac has a 17" monitor, but the power supply on that one is dead.
Can we swap out the 15" monitor for the 17" one? Any links for how to do that?
Thanks,
Barbara

Hello and Welcome to Apple Discussions.
I'm fairly sure the part numbers are different for the PSUs on these two iMacs. Could you let us know the processor speed against screen size for each one so we can check that out? ( menu > About this Mac)

IMac Dual Core - Airport conflict issue.

Hi folks,
I am having a problem with my neighbor. Not that he's even aware of it. I have a secured wireless network entirely locked down by MAC addy, and all that good stuff. When he powers up his LinkSys wide-freeking open "access point", my Airport goes bonkers, looses my strongest connection to my Netgear Extended-Range Router. I look at my airport status now greyed out, which now shows no network selected, and none available. Check it again in 10 minutes, shows mine and the Linksys one, OR shows just the weak linksys one and my mac asks me if I'd like to join that "access point".. Is there any way I can lock my airport into my Router Signal ONLY and not let this weak "access point" knock me offline? This is beginning to suck! Thanks in advance for any help/advise - and no, I would rather not go hard-wire.. 8^)

Thank you so much! I am still getting used to being "wireless" and seems my neighbors all use our systems at about the same times... I have made these changes and now, my wife and I shall enjoy our Macs when we want!
I hadn't realized I had set these options to be "automatically join".. Which probably really ***** unless one is "on the road".. I shan't be hoisting my 20" iMac out of the house .. unless we move! Thanks again for you quick and concise help!
In System Preferences->Network->Airport, select "by
default join preferred networks, and make sure your
neighbor isn't in the list. Under options, select
"ask before joining open network" and uncheck
"automatically add new networks to preferred networks
list".

How to keep full screen mode from blacking out 2nd screen with dual screens in windows

MSI gtx 570 twin frozr III - Dual Screen Windowed mode issues

Ok, so... I was running a solo monitor 1440x900 resolution, i recently purchased a brand new asus 24 inch 1900x1080 monitor. Basically what is happening is when i play WoW or Battlefield 3 in windowed mode on the 1080p monitor the colors are not perfect. When i go full-screen on the new monitor no issues, but that is not what i want to have to live with. When i say the colors are not perfect what i mean is, for example when i look @ the sky instead of being a smooth transition or blend from one shade of the sky to the next it is bars or stripes of each shade as if i am looking at the sky in 8 bit color instead of 32 bit color. Another thing to note is that when i login to windows 7 the blue screen where i input the password has the same effect. The 1440x900 monitor is running everything just fine. the only issue is with the 1080p monitor.
I am using DVI cabling for both, and have swapped them around to see if that was the issue, and sadly it is not. I am running the updated gpu driver, which i uninstalled and re-downloaded and installed again tonight.
When i use the HDMI cable, that fixes the issue but i need the HDMI for my 42 inch tv.
Also in windows, just to cover my bases with this post, i have the native resolutions properly configured, as well as in the game for the given monitor it is being played on.
Anyone know of a fix for this?
i7 2600k
asus PBZ68-v Pro/Gen3
Msi gtx 570
Samsung syncmaster 953bw (1440x900)
Asus VS248 (1900x1080)
I am more than happy to re-explain anything that may not be as descriptive or clear to you just let me know!
EDIT!
When i run the 24 inch 1080p new monitor as my only monitor on the system, everything runs perfectly...
Edit #2
Ok so i have pin pointed a possible cause
This msi gtx 570 struggles with operating multiple displays with different resolutions, while dual screening with my 1080p television and the 1080p display, everything runs as expected. Having to also render a 1440x900 display is probably the reason i am having the graphic issues. Is there any type of utility, setting, or other fix to this type issue? also this gpu is certainly less than 2 weeks since i purchased i could get a different card to remedy this... any suggestion? if you suggest a different card can you say so with certainty that it will work properly under the condition in which 2 resolutions will be required?

Ok, the problem is fixed and Svet i skipped a step or two. I installed the new driver with the clean install to save time for an initial attempt. What is interesting is that with the Geforce driver, only one 1920x1080 resolution was available
The msi driver gave me 2 options, 1920x1080 and 1920x1080 (native). The latter resolution fixed the issue for whatever reason.
The solution to this problem is so easy, when i purchased battlefield 3 it prompted me to download the geforce.com driver and i did not think anything of it at the time, lesson learned.

New window opens in main monitor when using dual screen

I am using dual screens and my "main screen" is on the left. Ever since Firefox updated to 32.0.1 on Monday I've been having this issue. Before the update, I would have my main Firefox window opened on the left and, when I click on a link to open a new window, it would open on the right screen. Now, it will only open on the left screen, where the other window is. If I drag the original window to the right monitor and open a link, the new window will open on the right monitor. But once I drag the original window back to the left, new links will open in the left again.
Before if I had this problem, I would simply drag the new window to the right monitor, then back to the left and close it. Then click the link again and it would open in the right. Kind of a work around I guess. But since the update, even this will not work. Any suggestions? Or is this a new function of the updated version? Is there a way for me to go back to the previous version? Any help is appreciated!

Hi hollytotheg,
I understand that links opening in new windows are opening in the active screen, not on the right, second monitor.
This may be helpful: [https://addons.mozilla.org/en-US/firefox/addon/monitor-master/] the search recommends this.
However I would also recommend suggesting an enhancement in input about dual monitor new window restriction.

Can I use my old iMac(late2009) as a monitor for my new iMac i.e. dual screens?

I have a iMac late 2009, just purchased this week,but not received a brand new iMac, i want to use both iMacs,the older one as a second screen.
The older one has mini display port, but no thunderbolt.The New one has thunderbolt,USB3 can i connect them together t ouse older iMac as a monitor?

so if thunderbolt is backward compatible,can I use a thunderbolt to Thunderbolt cable , would the data rate be increased if i did this?, Ive seen those available, but mini port to mini port seems to be more difficult to find, I take it that the mini port connection end of the cable is compatible with Thunderbolt. loads of variations of mini port with usb, mini port to firewire etc me

Problem with dual screen (24" imac 2006 ver)

hi
i've got a 24" intel imac (2006 ver) and i've connected it using apple's mini-dvi => vga adapter to my 2nd 22" lcd monitor, a samsung 2232GW, which is set to 1680 x 1050.
however, the samsung lcd displays (when i'm using as dual screen) is quite blur and double imaged. quality is readable but very irritating. i'm also using the same monitor for my ps3 (uses the DVI side) and have no problem with any visual aspect. I've tried playing around with the settings like resolution and calibration and tuning but didn't help at all.
anyone might have any ideas and enlighten me on this issue?
thanks

Did you get any resolution to your question? I have the Samsung monitor almost like yours, and I posted two seconds ago. I think I have a similar problem. I had been using my Samsung with my PC, and just switched to Mac. I loved my Samsung, but now ,for the first time using as a second. Hooked up to mini dvi to dvi, and reported a glow, or tinge coming around any window that I may place on the Samsung.Also, when Ilook at the background around the window I can see that the resolution is not perfect and is breaking up a little. Did you try VGA? and did it help? Curious to know

Mountain Lion Dual screen window Full screen problem?

I could not upgrade from Snow Leopard to Lion on my iMac because dual screen operation was broken when a window on one screen was set to full screen. Has this been fixed in Mountain Lion?

Hey Cuckoo
i Use an iMac with 2 dual screens and the problem you are describing is fixed in the final build release of ML.
i have not seen the breaking of activity when switching too full screen on even all 3 monitors. so looking good in the multiscreen support.

How do I play a video in full-screen mode on one screen of a dual-screen Windows 7 system without blanking out the other screen?

How do I play a video in full-screen mode on one screen of a dual-screen Windows 7 system without blanking out the other screen? Not losing the other screen would be useful as I would like to, for example, monitor my emails whilst watching a video or to work on a project whilst watching an instructional video.
Note : Resizing a window to fill the screen is not acceptable as it still leaves unsightly borders.

Black screen in Windows 8.1 on Late 2009 27" iMac

Hi,
My Late 2009 27" iMac i7 will not allow the display to turn on under Windows 8.1. It's not just black, its as though its powered off. This is some kind of a software problem. I am certain of this because I ran Windows 8.1 just fine since its release (10/17/2013). Hoestly, I ran it for months without a problem. I think it was an upgrade install over Windows 8 and not a clean install. Anyways, last week I upgraded to an SSD and needed to re-install Win 8.1. Now the display won't turn on. It works fine when you first boot it up after the setup runs, then a windows chime sounds and the screen goes blank and never turns on again. If you enable RDP before this happens you can still access the computer. I have re-installed Windows 8.1 and also I have tried BootCamp 4.0.4033, 5.0.5033, and 5.1.5621. None of them have enabled the display. Nor has the vanilla driver from AMD/ATI. I am at a complete loss as to what to do. My only hope is there are a handful of other users with this model of iMac who also have this issue and have solved it. If I ever find the solution you can count on me writing it in detail here in this thread or linking to a thread that solves it.
Thanks,

Summary: The ATI Mobility Radeon HD 4850 and other "legacy" graphics cards are not yet supported by AMD/ATI on Windows 8.1.
If you are disatisfied with a perfectly serviceable series of video cards being dropped from support make yourself heard: http://emailcustomercare.amd.com
---Details---
Okay after some pretty exaustive research I have found out a few things.
First, that AMD/ATI has decided to not include several series of "legacy" video cards in their support for Windows 8.1. This support may come in the future. There are conflicting reports about wether or not this is happening.
Second, there is a small community that is devoted to unofficial modified drivers that are supposed to allow legacy cards to be used on Windows 8.1. -> http://forums.guru3d.com/showthread.php?t=372799. I had no success whatsoever with these drivers, even on a clean install of Windows 8.1. I did get the drivers to install, but no games could start and Windows warned me about the drivers being unsigned frequently. So I would be hesitant to devote a lot of time to installing those drivers.
Lastly, I am pretty disapointed with AMD/ATI. Sure, the card is approaching its sixth year anniversary (~June 25, 2008) but it works just fine for most uses. It is a perfectly serviceable card for desktop uses. I just installed an SSD with the hopes of getting four more years out of this computer. I guess I will be religated to Windows7/8 on this machine till the end of its life. People considering the SSD upgrade may want to take this into consideration. I suppose its a non-issue if you are OK with using Windows 7 for four more years.
There seems to be a potential for upgrading the video card to the part used in the 2011 iMac, but for now that part costs $500 or $600, if its even stocked.
