Red desktop on second monitor problem

Hi,im having a strange issue with a cinema hd display set up as a second monitor on an imac, its showing the desktop fine but its all red coloured.
If i connect a 17" hanns g monitor using the dvi its fine but if i connect an lg monitor that shows up red aswell although the lg works fine on a pc.
Has anyone else had or know of this problem, thanks.

If it's happening with two monitors, it doesn't sound like a compatibility problem. In fact, it sounds a lot like what happens when either pins are bent or else connections are made loosely.
Try checking the pins to make sure none are bent over in the cable being used. Also, when the cable is attached, make sure the thumb screws that hold it down are fully tightened.

solved i think...
this from Kimomik on the flickr forums
Solved!
I had the same issue: Aperture 2.1, MBP and external display, color shifting in full screen mode.
Searching on the net, I found the following article on apple web site and applied its fix even if the article is dated from June 2006... It worked for me!
# Open the Color Sync utility, located at /Applications/Utilities.
# Click the Devices icon.
# Click the disclosure triangle next to Displays.
# Select your second display.
# Click the Make Default button.
Here is the article: docs.info.apple.com/article.html?artnum=303891
I hope it will work for you too.

Desktop icons off screen when removing second monitor

Hi there, well I have found a few bugs so far using Leopard so thought I should see if anyone else is getting them:
@ I use a second monitor, and if I remove the monitor, although the rest of the OS resizes to just the laptop, the desktop icons are nowhere to be seen.
@ My USB mouse doesn't work any more.
@ Although I prefer the way the connected servers now work, there is a problem in Finder, where I have to restart Finder to be able to see some connections.
Apart from that I am pretty happy with the speed improvements and there are less bugs for me than I had read about (although obviously as production software you would expect minimum bugs!).

I have the exact same problem, MacBook Pro 15" 2.33 GHz and the same type of Apple display. I use the display at the office, disconnect, bring my PB home, and when I wake it up the PB acts like the display is till connected - no desktop icons visible (although strangely, it shows the Dock and the Finder Menu) until after I restart.
Clicking "detect displays" doesn't work, neither does clicking the highlighted configuration.
My daughter also has a problem with her MacBook and her Apple Cinema display, which has to be set as mirrored or it won't display anything, it somehow isn't detected the way it used to be. Why I mentioned this is because I never had this problem before, and neither did my daughter. It started quite recently, so I guess it is related to a system software update.

Desktop icons won't move to second monitor

Happens peridocally. I keep my application bar on my second monitor, to the right of my main one. I also keep a lot of desktop folders and files on that desktop. Once and a while, I wake the machine up from sleep, with both monitors active and working, only to find that all the icons on the second monitor have disappeared from it and realigned themselve to the right edge of my main monitor. The application bar remains on the second. The icons will not move back.
Any idea why this is happening? I think the only way to fix it is a restart unless someone knows a better way.

Did you check your Displays preferences, Arrangement? That is where you define the relationship of the two screens and the main monitor (defined by which monitor you dragged the litte white menu bar to).
At the moment it is not clear to me why sleep would make your system forget the arraignment setting. One way it can happen though is if a monitor disconnects (or the system thinks it disconnects). You can reproduce te effect yourself by unplugging one of the monitor's video connections while both are on.
You said one of the monitors had disappeared so a disconnect may be indeed what is happening. Perhaps that monitor is slowly failing (power supply, whatever). Try running with just the problem one for a while to see what happens.

AE CC loses connection with second monitor and audio mixer (BLACKMAGIC) when switching to desktop

specifications:
Mac OsX 10.7.5
AE cc (part of creative cloud, up-to-date) NOT TRIAL VERSION
software for connecting monitor and adui mix panel: Blackmagic Desktop Video 10.0
second monitor: Sony Trimaster EL PVM 2541
audio mix panel: Behringer Xenyx x1204USB audio mixer
Blackmagic connects the Sony screen + Behringer Xenyx x1204USB audio mixer to the mac computer.
the problem:
When working in after effects, we link the program to show the video preview on the second screen (the sony one)
While the work area is still visible on the Mac screen.
The audio is also regulated through Blackmagic so we can mix on the xenyx mix panel.
Everything works fine as long as we stay in after effects.
If, for a brief moment, even a second, we swhitch to the desktop, or an other program (internet, acrobat reader, etc) After effects looses the connection to Blackmagic (forgets it exists). So we suddenly have no audio, or no longer a seperate video preview image.
The option to select Blackmagic in the dropdown menu is also gone.
If we restart After effects though, it's connected again.
Any ideas?
I added two screenshots to clarify.
The screenshots is when it does work, and after effects still recognizes blackmagic.
Cheers,
Andreas

When this happens, open Activity Monitor. Is Adobe QT32 Server running? That is required for QuickTime video preview. If it is not running, this is the troubleshooting you want to do:

In the next update to After Effects CC, the old QuickTime video preview (on Mac; DirectShow video preview on Windows) is being replaced by Mercury Transmit:

Is anyone else experiencing problems with the thunderbolt port on their Mac Mini's regarding using it to connect a second monitor? I've got the Mini Display Port to DVI-D adapter along with a DVI-D cable and I can't get an image on the second monitor.

I had an dual display image / setup working twice for a few seconds, but then it cut out. I think there may be a problem with the thunderbolt port.

As far as I can tell you have only listed that you have a DVI monitor connected to the Mini Displayport socket (i.e. the Thunderbolt socket) via presumably the Apple Mini Displayport to DVI adapter and a DVI to DVI cable.
You don't appear to have listed what the second monitor is and how it is connected (even though not working). As such I cannot tell what may be wrong.

Problems with my second monitor after upgrading to Mountain Lion

Basically I have a Mac Pro 8-core with two video boards (2 x NVIDIA GeForce GT 120 512 MB) connected to two monitors. After upgrading to the Lion Mountain, 90% of the time when I start my MAC the second monitor doesn't show it image, keeps in full black screen, what puzzle me is, I can see the mouse arrow on it, so its alive, but its in black, than I have to restart the computer over and over again until it finally make the second shows it contains.
Have anyone experienced the same problem?!

Hello Carlo!
Sorry but I don't understand which part of my question is not clear. I've been to the Apple Store, they asked me to bring my 20kg Mac Pro and both 24" inches Eizo monitors to central London to have it checked. Well, honestly, this is impossible, is an invitation for an accident.
Is just unbeliavable that no one has experienced my problem, looks like I am the only one person with two monitors using the Lion Mountain.

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".

Bonjour,
Travailler avec 2 écrans ? Je suppose que ma question est la même, mais je ne suis pas sûr !?!
Question : si l'on branche un 2e écran sur la prise monitor d'un iMac 20' (2006-01), est-il possible, de se servir de ce 2e écran pour y mettre les palettes de ces logiciels, tout en ne gardant que la fenêtre principle du fichier sur l'écran de l'iMac ?
Merci.

Can my computer display 'extended desktop' with a second monitor?

I believe I have a G4 Quicksilver 867 (2001) (bought it used and figuring out which model G4 is not that easy). I recently got a second monitor, but I only seem to have the option to have a mirrored setup (which works well). Is there anything I can do or rather what are my options to get it to show extended desktop. My video card is
Chipset Model: GeForce2 MX
Type: Display
Bus: AGP
Slot: SLOT-1
VRAM (Total): 32 MB
Vendor: nVIDIA (0x10de)
Device ID: 0x0110
Revision ID: 0x00a1
ROM Revision: 1049
Will I have to get a new graphics card or is there a workaround of some sort?

Thanks, not what I wanted to hear, but helpful. hope you'll answer a couple of questions. I bought this computer as a second (do taxes, surf the internet, connected to my wireless router, escape my three kids wanting to use the primary). I've been very happy with it for its limited use (my primary is one of the first Imac G5's).
1st: Do you think it's worth putting a faster processor in it? My G5 has the latest OS, but I'm hesitant to go past 10.411 with the G4 867
2nd: Would you recommend a video card update to run extended desktop?
3rd: Can you run extended desktop on the original IMAC G5's (1.8 ghz, GeForce FX 5200, 64 mb ram)?

I upgraded to 10.10.1 today and the brightness dimmed on my mac monitor - I've checked both display and accessability and dont see a problem. My second monitor which is not a mac monitor is bright still.

I have a second generation shuffle and even though (after charging ) the green battery light is on - soon after it turns orange and then red. Is there a problem with the battery and is it fixable?

I have a second generation shuffle and even though (after charging) the green battery light is on it soon turns orange and red. Is there a problem with the battery and if so is it fixable?

If it's a 2nd gen shuffle, it is probably about six years old at this point. The cause is likely to be a worn out battery that is no longer able to hold its charge for very long.
It is technically fixable. This web site has repair guides
http://www.ifixit.com/Device/iPod_Shuffle
But it is very small, so you need to be good at doing such things. The cost to have a repair shop do the work is likely to be uneconomical, compared to the cost of a brand new 4th gen shuffle ($50), which has more features (and possibly double the storage) plus a one-year warranty.

Problems with second monitor

Hi all,
I have a MBP described bellow, and I have a problem, started after I changed the background image (I don't know if its had to do) to change each 15 minutes.
After this change, the second monitor started to be scratched, unreadable and freezing my MBP. Only solution was disconnect the mini port and force shutdown the machine. I tried this actions some times, but now, MBP doesn't recognize mini port any more. What might be happening?
OSX 10.9.5
2.5 GHz Intel Core i5
4 GB 1600 MHz DDR3
Intel HD Graphics 4000 1024 MB

Thanks in advance.

I have a macbookpro with a second monitor connected using an Apple connector. The two screens show different parts of the desktop. My cat walked across the keyboard, and now the two monitors are showing the same thing. How do I undo what the cat did?

Have you tried HELP in FINDER? If you open HELP and enter 'displays' in the field in the upper right hand corner you will get a list of topics on setting up monitors. Specifically read 'Setting up multiple displays to show the same image' and 'Setting up multiple displays as an extended desktop'.
Ciao.

Envy 15t-J100 Problem connecting second monitor

Hi!
So I have that problem that I want to know if someone ever had or have the answer for.
Each time I plug a second monitor using an HDMI cable, in order to get it to work I need to go to the device manager, disable and enable the Intel HD 4600 driver.
It's was OK when I used to connect the second monitor once in a while.. but now I use it on daily bases and each time it goes to sleep mode I need to do the disable/enable thing again.
Please let me know if you have any solution,
Thank you,
Ron.

@Berkomb ,
Hello and thank you for posting on the HP support forums. This issue may be due to a possible update from Microsoft. If an updated driver has been loaded that is not from the HP support site it may cause a change in functionality.
You may want to try a system restore back before you noticed the problem.
