Second monitor wallpaper disappears

Ever since I installed 10.7.2 I've had problems with the desktop wallpaper on second monitor disappearing. Its;m replaced at random intervals by neutral gray screen. Icons remain and everything works, just wallpaper is missing. If I turn the montor off and then back on wallpaper reappears and then some time later it goes away again. Yes, I've checked the cables
I'm stumped and have googled my brains out. Anyone have a solution of is it a bug?

I have exactly the same problem. Mostly happens after the wakeup.

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.

How can I make disappear the finder tool bar in the second monitor?

How can I make disappear the finder tool bar in the second monitor?
(I have to use ProVideoPlayer, a professional application for presenting videos and I really need a clean second monitor!)

After changing that setting and logging out and back in as it indicated, do you still have two menu bars?
If you are already set up that way and want to move the menu bar to the other monitor, drag it there in the Arrangement tab of the Displays system pref.

Photoshop CS6 goes crazy on my second monitor now I have updated to Mavericks

I've had a look around to see if anyone if having the same issues but haven't come across anything to help yet.
When I updated to mavericks my java installation disappeared & so Dreamweaver wouldn't work. Now I've installed jdk-7u51-macosx-x64.dmg & it's working again.
However now I'm seeing an issue with Photoshop CS6 when I drag it across to my second monitor- see image below
The only way I've found to get rid of this weirdness is to drag the screen back to the primary screen and wait for it to settle. Dragging the screen in itself is really laggy & I can sometimes manage to get it to appear normally on my second screen if I wait a bit or wiggle it around. But this time I can't even get the window to appear on my screen at all. It's as if the programme isn't open any more. But if I select 'show windows' I can see it is still open & still flashing with the mess shown in the image below.
Really quite frustrated with Apple about this, now I can't brag as much about how amazing macs are compared to PCs!!
Help?!?

The Mavericks Mac I'm writing on still has CS6 on it so I'll see if it happens to me when I'm near my desktop monitor.
Well, I just tried moving the Photoshop CS6 window around between two monitors in Mavericks and didn't get the same problem, so I really don't know what the problem is. But you could try asking at the actual Photoshop user forum since they'll know better questions to ask than we would in this forum.

Late 2009 imac as second monitor

Hello, I just purchased a new iMac retina 27 inch. I am trying to use my late 2009 iMac 27 inch as a second display using a mini display port. I can get it to work my old cheap second monitor, but when I try the 2009 mac, and I press command F2, it shows the options to set up as a second monitor on the new retina mac but then after a few seconds the options disappear and they go back to being separate monitors. Just wondering if anyone has been able to make this work as I'd hate to have to sell my 2009 mac. Thanks in advance.

You're starting in Target Disk Mode not Target Display Mode. Follow these instructions:
Make sure both computers are turned on and awake. (This is where you're going wrong)
Connect a male-to-male Mini DisplayPort or ThunderBolt cable to each computer.
Press Command-F2 on the keyboard of the iMac being used as a display to enable TDM.
Note: In Keyboard System Preferences, if the checkbox is enabled for "Use all F1, F2, etc. keys as standard functions keys," the key combination changes to Command-Fn-F2.

Duplicate mouse cursor appears (but doesn't move) on second monitor

I have a Mac Pro with the ATI XT1900 video card and 2 Dell 2407WFP LCD monitors attached via DVI.
When I'm using an application, such as a web browser, and the cursor changes state (like the black arrow with spinning wheel in corner) a duplicate of this cursor state appears on my second monitor, on the left-hand side of the screen.
This cursor DOES NOT MOVE, but does animate, and will not disappear unless I move my "live" cursor over to the second monitor, which I imagine causes OS X to "refresh" the position of the cursor. It realizes the duplicate shouldn't be there and it vanishes. The second cursor seems to appear only when the primary live cursor changes state, as in the black arrow becoming a black arrow with spinning wheel in the corner, etc.
This is not a duplicate cursor due to having Displays set up to mirror one another. The second cursor doesn't move.
This has happened in more than one software application, so it appears to be some sort of display driver error at the system level.
Anyone else experience this or have a way to fix it? There have been several Apple Updates to OS X since this problem first started happening (on day 1 with the Mac Pro) and it has not been resolved.

Can Second Monitor Play VLC Videos?

I use a mid 2012 Mac Pro; run Mavericks. I plan to use my TV as a second monitor. I know that I have to use AppleTV to connect wirelessly to my TV. Will AppleTV allow me to play "VLC" videos?

Sounds like you have "other" issues, perhaps a corrupt cache file.
Backup your data off the machine just in case and disconnect all drives, then run all of OnyX's maintenance and cleaning aspects and be sure to reboot at the end.
See how that works for you, like giving your OS X a enema.

No zoom level controls on second monitor!

I use a second monitor to display a loupe view of the photo I have selected in the grid view, which is on the first monitor. I have always had the zoom-level controls (Fit, Fill, etc.) at the bottom of the loupe display on the second moitor, until I replaced my first monitor this week. Everything else is still the same, but I no longer have the zoom controls on the second monitor. This means that I cannot change the zoom levels that are availabel to me. I either have Fit or 100% zoom. Without the zoom controls on the second monitor I can't change the settings. Does anyone know how to get the zoom controls back (or why they might have disappeared)?
Thanks for any help.

Never mind. I found the problem (the second monitor was in full-screen mode). Nothing
to see here. Keep moving.

Second monitor very dim on Vista 32 Boot Camp 2.1

I have a NVIDIA GeForce 7300 GT graphics card driving two Apple Cinema HD monitors (first is 23" and an older 24") and after installing BC 2.1 the second monitor becomes dim and the NVIDIA control panel can't be used to get a satisfactory setting nor does the brightness button at the front do anything. The 23" monitor is fine and the brightness buttons on the side can be used perfectly. When I run OS X I find the brightness has been turned down to the minimum setting on the 24" monitor- having changed it in display properties on OS X, it becomes dim again when Vista is started on BC (it remains bright during the startup process for Vista!). It seems this is a BC 2.1 issue as when I roll back to installation disk drivers the problem disappears. Any ideas?!?

Hi Stefan
Thanks for the suggestion. However, in the Boot Camp Control Panel with BC 2.1 I have two tabs (Startup Disk and Power). I seem to recall that under a previous version there was a Brightness tab. This may be a problem with BC 2.1 installation- I can't seem to locate drivers install facility for BC 2.1, only Update to 2.1 seems to be available.... Kuldeep

Why won't my second monitor work?

Hello,
I am new to the forum, as well as macs, and had a basic question I was hoping to get some assistance wit
I've got a 13" macbook pro, and cannot get a second monitor to run on it. I have purchased the Mini Display Port to HDMI adaptor, but when its all plugged up, its a no go.
The monitor (Samsung SyncMaster) will show activity when plugged with the HDMI (running through diff input sources) and the screen on the 'puter will go blue ...
After this, however, the screen on the Samsung remains blank and appears to be in sleep mode.
Any thoughts or suggestions would be greatly appreciated.
Thank you in advance,
S

On your computer, if you open the Displays preferences and do not see an Arrangement tab (or there is an Arrangement tab that shows only a single monitor) then there is something physically wrong with your connection. Try clicking Detect Displays just to see if the computer can now sense the presence of the connection. Check your cables and make sure the mini-displayport plug is pushed firmly in so that essentially all the metal part disappears inside the socket. Mini-displayport plugs can be a little tricky in that you need to make sure the plug is fully seated in their socket.
If you do have an Arrangement tab, and it shows two screens, then click Gather Windows to bring the second monitor's Displays preferences on to your main screen if the second monitor is not yet showing an image. Set the proper resolution. Set the refresh rate if that preference is shown. You should see a picture at this point.
Specifically which model Samsung SyncMaster?

XWindows/Quartz apps on second monitor

I have some Windows apps that I run using WineSkin (I believe uses XWindows/Quartz for the UI). After upgrading to Mavericks they would not show any display to the screen, but I found another thread mentioning that you had to reinstall Quartz after installing Mavericks. That fixed my first issue.
My second issue is when the apps open on my primary monitor on my MacBookPro, it's not possible to drag the open app to the second monitor. The mouse moves across to the second screen but the app window doesn't move with it - the window just moves off the screen and disappears. I can drag any other native OS X app between monitors and that works fine, but an app using XWindows/Quartz does not want to display on the second monitor.

Yes Maverick install is messing with X11/XQuartz. A reinstall of Xquartz fixes that.
For the monitor situation I found this on the X11 mailing list:
A work around is to go into System Preferences->Mission Control and uncheckDisplays have separate spaces.
This will put you back into a sort of legacy mode. The new dual monitor features of Mavericks won;t work but X will behave as it did before.
According the mailing list this is a dual problem. There are some changes that need to be made to Xquartz and there are problems in Mavericks. The Xquartz team can only fix there end. Apple will need to fix their end to resolve this as well.
BTW if you are not aware of it there is an Xquartz mailing list where question like this are better asked

How to sychronize second monitor to be an extension of my 20" iMac

I have a second 19" Flat Wide Screen Monitor next to my 20" iMac. However, there are a couple of things that I don't know how to adjust.
1- The Wallpaper on both monitors are different how can I have the same Wallpaper or the same rotation of images to be the same on both monitors
2- I can't sychronoze both screen to display the same size for the browser or whatever I'm viewing. I have gone to Display and to Arrangement and moved the second monitor up or down but somehow the page on the second screen RT side it's about 3" longer. How can I make the Browser or page extend to the second screen appearing exactly or close to the same size as on the iMac

What Al said is correct. With two different size monitors you will not be able to have things "line" up. Your primary display, in this case the iMac, is what your settings are based on.
Lets say the bottom of both of your monitors are at the exact same height and the top of your iMac is 2 inches taller than your secondary display, if you were to slide a window that was aligned at the top of your monitor over to your secondary display, the top of that window would be cut off by that 2 inches. As far as your computer is concerned both monitors are at the same height.
Another example is to draw an imaginary line from the top of your iMac display across to your secondary display, Your window that you slid over in the previous example would be inline with that "imaginary" line.
Like Al said in his post, if you want things to line up you need two monitors that are the same size.
I use my secondary monitor for (a 20" Samsung) to house all of my tool pallets when working in graphics programs. Or if I'm working on multiple things at once "multi tasking" I'll move some of the windows over to the other display for reference.
I hope I didn't confuse you even more, it's a bit difficult to explain without visuals.

I managed to get it working again but i can't get the resolution higher then 640x480, It should be 1920x1080
edit:
I had to unplug my monitor and reboot.Then i pluged it back in and used gksu/kdesu nvidia-settings and got a resolution of 640x480.After that i just had to reboot again and everything was back to normal.
Also ,the files that were missing from my /home/user/ where easily replaced from the /etc/skel directory and any others that were missing like my .rtorrent.rc just had to be re-downloaded and configured again.

How to connect my Cinema Display as a second monitor

I just purchased a new 27-inch iMac, and I explained to the Apple folks that I had a 17-inch cinema display (silver clad model) that I wanted to connect, for a dual monitor set up. They told me just to get the Mini DisplayPort to DVI Adapter, but I was surprised to realize that's not going to work.
Can anyone tell me how to do this, and what connector is actually needed? I have the big old white power brick that I bought to daisy chain my old 17 and 23 inch displays with my old configuration (Mac Pro).
Or can you not have a second monitor with an iMac?
Thanks in advance.

Lightroom 5.4 jumps to second monitor when attempting to edit an image in Photoshop CS 6.

Hello,
I have a brand-new HP z620 with an Nvidia Quadro K 4000 display adapter and apparently a software and/or hardware conflict.
I am experiencing an issue with Lightroom 5.4 window not working correctly with my second, not primary, monitor. When Lightroom is working on the second monitor and I need to edit an image in Photoshop cs6, I want Lightroom stay where it is and Photoshop to open on my primary monitor. And this has worked well for me on my previous system which was also a Windows 7 64-bit machine with an Nvidia GeForce GTX 570.
When I click the Lightroom option to "edit in Photoshop CS 6” The Lightroom window will move itself to the primary monitor for no apparent reason. This is the problem I am seeking to remedy.
No other external editing programs opened through LR behaves this way, such as NIK or OnOne Perfect Photo Suite, and I really need LR to stay on the second monitor on the extended desktop.
I’ve tried every monitor cabling setup I could think of to try and even unplugging the primary to make windows identify it as the 2 monitor in the screen resolution settings, but that does nothing for me. My new workstation is running the same OS version and a K4000. Monitors are currently connected to the display ports via dp to dvi adapters. I’ve already tried moving the connections around and plugging one into dvi, there doesn’t seem to be a setting I can change within windows or adobe to change this behavior.”
On a related note, I have similar instability in software made by X-rite that supports the use of a colorimeter allowing me to build profiles for monitors and evaluate colors precisely. During the profiling process I place the colorimeter in the designated place on the secondary monitor and direct the application to begin showing the colorimeter different colors on that monitor. At this point the colors jump to the primary monitor while the rest of the interface along with the colorimeter is a secondary monitor. I have a workaround that I'm using for this particular problem but I am fairly sure that the issue that causes the problem with Lightroom is also the source of my trouble here and I need to eliminate it.
thanks for your time,
Larry Garvey
