Strange multiple display problem

I have two displays hooked up to my powermac G4 733 (still works great).
recently after I launched Avid Xpress Pro (I'm sure it's the cause), one of the display's stopped working. It's not getting signal from the computer.
The strange part is that in the displays section of my system prefs, the second display is showing up (it's also showing up on my system hardware list in "about this mac")
Even under arrangement the second display shows up.
I do know that the connection between comp.-monitor is good. When I hit "detect displays" the other screen does come on and flashes twice showing a mirroring of the left monitor (even though mirror displays isn't checked).
I reinstalled the OS, but didn't help. Any ideas?

Unplug the power. Open up the G4 and press the CUDA button. It is a small black button located on the Motherboard. Press and hold it for 3 seconds. Then plug back in and restart. That will reset the motherboard, not sure if this will do the trick but give it a try.

Multiple display problems

I have a mac mini with mavericks and I am using multiple displays. I am having a several problems. The first one is when I use a program like vlc, quicktime, itunes, etc... and go fullscreen, my second display goes black. I found one way around it but i was wonering if there was a setting or something that I missed. My second question if I have a video playing in one screen, can i have the sound come from that and in my other screen have my game playing and have the sound com from that display instead of it both commin out from on source?

The screen going black is up to each app. Often with video apps it will darken the second screen for an uninterrupted experience but has an option to turn it off. I don't use VLC, Quicktime or iTunes for video but if you use MPlayerX or MPlayer OSX Extended for example you simply go into the settings and uncheck the black out second screen option.
As for audio, it gets complex. There are apps which can route sound to a designated device (like each monitor and mini-jack cable). Several video players can let you select an audio-out device; this means while you let your game go to the deafult while VLC for example would go to your designated monitor.

Strange freezing/display problem

Hi,
I've recently started having some strange problems with my 24" iMac 2.16GHz.
What happens is the screen freezes, not just the application I'm working in, but the entire screen. If I move the mouse it looks like the screen tries to redraw itself so I might get a browser window half-duplicated and then other windows look like they leave a trail if you try to move them. I can't click on anything, I can move the mouse for about 10 seconds, then I get the coloured beachball and I have to restart from the back.
A couple of times when I've restarted there has been a high pitched tone before the start-up chime.
I can't say exactly what I was doing when the crashes happened but a couple of times I've been looking at videos on YouTube. It may be related, I'm not 100% sure though.
I can't really explain it any better than that, sorry it's not as clear as it might be. I can't take a screenshot or anything when it happens.
I've run Disk Utility from the OS CD to repair the disk and it didn't find any problems. I haven't installed any new hardware or anything like that.
If anyone had any idea what I might try to find out what's going on I'd really appreciate it.
Thanks.

Sorry to bump this but this issue is still ongoing with me.
I'm nearly positive it is caused by watching videos on YouTube, Googlevideo etc. It just happened again while on YouTube. Screenshot - http://img220.imageshack.us/img220/342/screeniu8.jpg
After about 20 seconds I can click around and the screen goes back to normal when I move the windows. It's almost like using the eraser tool in Photoshop or something, you can 'wipe out' the bits that are not where they're supposed to be.
Yesterday I reinstalled the OS, I did an erase and install as well. Does this mean my graphics card is the problem?
Any advice on this would be a great help because I've got a huge amount of work at the moment and this is proving really disruptive (and before you say it I was taking a break when watching that YouTube thing!).
thanks

Strange ibook display problem

My wife has a 12" ibook g4 1.33 mhz. It has been exhibiting the following symptoms with increasing frequency:
1) the display will completely dim to the lowest setting or cycle between bright and dim, as if pressing f1 and/or f2 repeatedly
2) some of whatever she was typing or working on at the time will be deleted
3) a string of repeated characters (usually q1aq1aq1a) will appear in her typing
4) often the desktop is brought to the front as if pressing f11 in expose
5) other than the problems described, the computer continues to work normally
6) problems are almost always related to moving the hinge position, but sometimes happen randomly, with no movement at all
7) it will sometimes occur many times a day, then not at all for several days
8) it seems to happen more often when the computer is not on a hard surface, but this may just be my imagination or some random bad luck
I am at a loss as to what the problem may be. I was thinking it might be the display cable because of the link to hinge position, but that wouldn't account for the random typing. Then I thought it was the motherboard, but the computer seems to work ok other than this. I did realize the other day that most of the problems are things on the left hand edge of the keyboard (display brightness, the q1a pattern), but this doesn't account for the deleted typing and the mysterious f11 thing.
Does anybody have any thoughts? Am I looking at a display cable (hopefully this is it - I have no problems with disassembling/reassembling things)? Or is it the motherboard (probably means it would be more economical to get a new machine)? Or is it something else?
Thanks for taking the time to read all this, and I appreciate any help you can provide.

Thanks for the suggestion, Richard.
There was definitely never any liquid spilled. I'm not totally convinced that the keyboard is at fault, mostly due to the problem being linked to the position or movement of the hinges. Could the keyboard be flexing when the lid is moved? But, I figured it couldn't hurt to try your idea out.
I didn't have an external keyboard handy, so I exchanged it with the one from my other ibook. I would have expected the problems to have followed the keyboard if that was the issue, but both computers are functioning normally so far. I have no way to tell if this means something, or if I'm just in one of those lucky streaks where it works for a while before the malfunctions pop up again.
Any other ideas?

Multiple Displays Problem - 3rd display shows pointer arrow only

I have a Mac Pro with two Nvidia GeForce GT120 video cards driving three displays. After the upgrade to OS X 10.8, the third display is recognized by the system, but does not show the desktop or any windows... only the pointer arrow is displayed - but the arrow is displayed properly, is mapped properly across all three display spaces, and the system still allows windows to be open (but invisible) on the 3rd display. Is this a general bug or perhaps unique to my configuration?

Mountain Lion Bug: 10.8.0 and 10.8.1
MacPro 4,1 + Dual NVIDIA GeForce GT 120
30" Apple LCD + 23" Apple LCD (rotated 270°)
When computer boots, the rotated display is black; although mouse pointer shows fine. If I physically hot-swap both DVI connectors, one on each card, everything works perfectly until I reboot.
Then after shutdown for the day, reboot the next morning, I have to swap the connections again. Then it works fine.
Come on Apple, there is a serious problem here that was brought-up since 10.8 FC and was ignored in 10.8.1.

Multiple displays problem

Since I upgraded my Mac mini to Yosemite, the secondary display (Thunderbolt->HDMI) is not showing nor detected.
What is wrong and how do I solve it?

*** I'm posting this on all similar questions hoping someone will read it and help everyone out ***
I was having the same problem with Yosemite and thunderbolt to HDMI but have found a sort of a solution or at least a bit more info that might lead to someone having a eureka moment. I have a Mac Book Pro, my partner a Mac Book Air. I bought a thunderbolt to HDMI cable from eBay so my partner could plug her Air into the TV. When the cable arrived, it would not detect our LG TV from either computer. So a bit of playing around and this is what I found.
I plugged the cable from my Pro direct to the HDMI port on the TV and nothing.
I also tried from the Pro to the HDMI port on the amplifier of the surround sound system and again nothing.
However, if I plug the cable from my PRO directly to the TV HDMI and select that HDMI port on the TV initially still nothing. But if I then plug a normal hdmi cable from my amp to the Mac Pro's HDMI port, suddenly the thunderbolt cable works and the Display Preferences see the LGTV. I checked that the correct hdmi port was selected for the direct connection and I could even turn off my amplifier to make sure that I was not seeing the wrong signal and it still worked.
It seems that there needs to be either a base signal or an earthing through the MacBook Pro's HDMI port for it to switch into an external monitor mode that will detect a thunderbolt to HDMI connection. This is fine for my Mac but as my partner's Air only has a thunderbolt port and no HDMI port it still doesn't work with her MAC.
Hopefully someone will see this and have a brainwave.

Multiple display problem in OSX 10.9.2

I just updated to 10.9.2 on my 15" Macbook Pro (Mid-2010) and after the restart my secondary display will not work. When I plug it in to my mini displayport my secondary display comes up black and my primary display comes back with the background and settings that I had set for my secondary display. It seems as though the OS was confusing my primary display for my secondary. After messing with the settings I was able to get my primary display back to my primary settings, but the secondary display is still showing up black no matter how much I mess with the display settings in the system preferences (changes to resolution, mirroring, ect.). Anyone else experiencing this?

My friend just upgraded, and while the second monitor works, (15" Retina macbook Pro and 27" Display (displayport version, not TB version), if selects mirroring, the MacBook display sets to the same resoluiton of the external display, but the external display goes black. Turning mirroring off does not correct it, the only thing he can do is unplug the 2nd display and plug it back in. When he does this it resets the defaults of the displays, so he has to go to arrangement each time.
PITA for someone who teaches a lot, not sure if it is going to be a problem with a projector or related to the display. Something broke ... appears they rushed this update out for the SSL issue without testing enough.
edit: just tried this with the newer Thunderbolt display, same problem.

T450s Multiple Display Problem

I have a relatively new T450s that I'm just breaking in. When I plug in an external monitor it automatically puts it on the right of the main display, but I want it on the left. So I go into the settings and drag the monitor icon to the left of the main display, but it won't stay. As soon as I exit out (or hit 'detect') it reverts back to having the external display on the right. I can't get it to stick. Any ideas?
Solved!

Multiple display problem

I have a 2010 2.8GHz Quad core all stock no upgrades. It is currently connected to a VGA monitor with a dual link DVI to VGA adaptor through a KVM switch and all works great. I am trying to connect a Vizio TV via mini displayport to HDMI then cat6 HDMI extender. If I plug in he TV when the computer is sleeping and I wake it up the two work fine for about 30sec then the TV says no signal and the VGA monitor cycles between the desktop and the extended desktop of the second monitor. Any thoughts?

TV alone also works. So the two together are the only problem.

I have a strange second display problem.

I have a late 2007 20"iMac with a Dell UltraSharp 18" second display. I am running Snow Leopard with all updates.
This setup has been working great for some 3 1/2 years up to about two weeks ago. Suddenly it is like the left 20% of my second display is unresponsive to the mouse, display is displaying everything OK and the muse pointer can move there, but the click is not doing anything. For example, if I put a Safari window on this screen and click of any of the links in this area nothing happens, however if I move the whole Safari window so the left side is 20% or more from the left edge of the display the same links are just fine.
Anybody ever seen this and know how to fix it?
Thanks, Bjarne

OK, no trouble shooting. The first thing I'd attempt is restarting in Safe Mode. If you still don't have luck try doing both a SMC and PRAM reset, it wouldn't hurt to do the SMC reset a couple of times. If still no luck let us know.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

K7D Master-L graphics problem: multiple display adapters/no winxp star

Hiya,
I just recently bought a new K7D Master-L and I've had a few problems with it. Other than these issues the board has been great, but this is getting pretty annoying and I can't seem to fix it, so I'm posting here for advice/help/solutions.
System Specs: I have two AthlonMP 1900+ and 786MB Corsair RAM (registered PC2100, 512MB in slot 1, 256MB in slot 2). I have a WD400JB (40GB ATA100 drive with 8MB buffer) and a generic IDE CD/DVD-ROM. I have an ATI Radeon 9700 Pro AGP card running at 4x.
When I first installed the motherboard I tried to load Windoze XP on it (actually I first used Linux but had ...driver problems). Anyway XP seemed to install fine, but upon reboot, the system would get to the "progress bar"/"OS loading" screen (the small blue bar that goes back and forth) and the bar would get stuck exactly 2 "bars" from where it started--every time. I could boot into safe mode, but nothing seemed screwy. Doign the command-line boot (I think) where it shows the drivers it is loading, it got to the "agpgart" file then stopped, maybe this was the problem. I gave up after a dozen reboots or so, trying various things, and installed Windows 2000+SP3.
Win2K installed fine, and after installing the drivers on MSI's site for northbridge, southbridge, audio, and lan, and installing ATI's latest Catalyst 3.4 drivers (I also tried 3.2), device manager had no more problems, save one.
The problem is that there are two display adapters listed: "RADEON 9700" and "RADEON 9700 (Secondary)". There were two adapters listed before I installed the drivers, called something like "Display Adapter" and "Display Adapter (VGA compatible)". In Properties it says "PCI Slot 4 (PCI bus 1, device 5, function 0)", is this normal for AGP cards? Here is a screenshot (I disabled one to see if that helped my settings-loss problem, but it doesn't):
[ALIGN=center][/ALIGN]
Whats worse is that the display settings don't seem to stick around across reboots--it always reverts to the default settings of 640x480x16--which is extremely annoying. These problems exist regardless of whether I have a Service Pack installed (currently I'm running on a fresh Win2K install with no updates and having the same issues). I've tried multiple drivers for the card and no change, I've tried with/without the updated chipset drivers, and I've had this same setup work on my previous motherboard (Tyan Tiger MP) without seeing multiple display adapters.
Any ideas? Or is there something that might fix my WinXP startup freeze? If so I could reinstall WinXP and see if that has the same multiple adapter problem...
Thanks for any advice.
Josh

Well my system just booted into 640x480x16, so it appears those registry changes didn't fix the issue. The registry settings were simply changed back to 640x480x16 for some reason. I haven't reinstalled the motherboard drivers, but I gathered them all up and I'll try this later today. Here are the latest drivers I found, all from MSI's site:

We shall see if this fixes the multiple adapter problem. As far as the display settings problem, I don't know that the deal is. It works fine on other motherboards with the same hardware and drivers, so it must be something with the K7D, Windows, and ATI interaction.

P.S.: There is a bug with this forum software and apostrohpies. Every time you preview your post it inserts escape characters ("\") before apostrphies, and also inserts escape characters for these escape characters, so quickly you have something like "\\\\\\\'" where you want "'".

T530 multiple display configuration

I have the T530 with the NVIDIA Optimus option that should allow a triple display configuration (two external displays and the laptop LCD).
I have been able to get a working configuration with the laptop LCD and two external displays over DisplayPort through the docking station.
I have found that upon some boot cycles, I am either stuck with just the laptop LCD as the only display or I am able to turn on only one external display. Sometimes a reboot will change it, sometimes it will not.
What's strange is that the NVIDIA control panel and the Windows display settings show all three LCDs, I am just not able to turn on one or both of the external displays (even if I turn off the laptop LCD).
Has anyone found a solution to this problem?
Thank you!
Solved!
Go to Solution.

Hi, admarsha
There are updates available for both your BIOS and Optimus that may help this issue. The BIOS update can be found here and the Optimus update can be found here. Looking over the ReadMe for the Nvidia update, part of the update does help with issues connected to multiple displays through docking stations so it may help.
Best,
Adam

Analysis Authorization based on Hier node with multiple display hierarchies

Hi guys - I've got a problem where s.o. might have an idea of how to switch on the light at the end of the tunnel, I am currently standing in:
Requirement:
Cost Center Authorization should be given through RSECADMIN, reporting should be possible for any hierarchy that exists for the authorization relevant info object.
Preferred solution:
The Cost Center Analysis Authorization should be given through RSECADMIN - Hierarchy node assignment.
u2022     A dedicated Authorization Cost Center Hierarchy will be maintained in ECC6 as an alternative cost center hierarchy and extracted into BW.
u2022     The RSECADMIN Hierarchy node assignment should be based on a particular node (Type 2).
u2022     The display level will be specified as required (here: Level 7)
u2022     The Authorization granted should be independent of hierarchy name and version (validity 3).
Reporting Scenario and technical impact:
As mentioned above, when designing and running a query the user should be able to freely select other (i.e. than the authorization) display hierarchies for the authorization relevant reporting object 'Cost Center' as well. The technical names of the semantically relevant hierarchy nodes could therefore vary. E.g. cost centers 1, 2 and 3, being assigned under hierarchy node u2018Au2019 of the RSECADMIN relevant authorization hierarchy, could be subsumed by hierarchy node u2018Bu2019 in another display hierarchy, which the user may want to display in accordance to his reporting needs. Ideally, the alternative display hierarchy should therefore display node u2018Bu2019.
My findings so far (based on prototyping) turn out that this is not possible as long u2018Bu2019 (and its hierarchy) is not authorized in RSECADMIN. Can these findings be confirmed? And if not, would anyone have an idea of how to facilitate the reporting scenario?
Would there be any other way to grant access, possibly based on RSECADMIN single values, and also enable the user to flexibly display hierarchies with only those hierarchy nodes whose single cost center values the user has been given access to?
Thanks everyone for your input...
Claus

HI CLause,
On Jul 14 2009, you wrote in SDN and said:
FYI: Found a solution...
The hierarchy analysis authorization will be based on a navigational attribute of cost center.
With analysis authorizations it is possible to declare the Auth object (e.g. 0COSTCENTER__RACCAUT0) as authorization relevant and leave the superior object 0COSTCENTER auth irrelevant.
The auth will be given for 0COSTCENTER__RACCAUT0. This object will be placed as a filter of the query, being restricted by an Authorization variable for hierarchy nodes.
Due to the concept of Analysis Authorizations, this variable will automatically pick up the nodes granted as part of RSECADMIN Hierarchy based Authorization.
As mentioned above, 0COSTCENTER as the regular reporting characteristic remains auth irrelevant and can therefore take any hierarchy thatu2019s available. Reporting on single values will be possible, too. Only those nodes show up that hold the authorized cost centers in accordance to the authorization.
If the auth relevant 0COSTCENTER__RACCAUT0 is not used in the query definition by either not taking it in as a filter or skipping the Auth variable, the query will launch the message that the authorization is missing. No data show up at all.
Claus
See this thread:
Analysis Authorization based on Hier node with multiple display hierarchies
I am also in the same situation as you and need to understadn your solution. I understand that you created a Nav Attr on 0COSTCENTER and made this auth relevant whilst ensuring that 0COSTCENTER is NOT auth relevant. This is all fine. The issue was you have multiple hierachies for 0COSTCENTER, how did the new Nav Attr help you solve your issue. When loading 0COSTCENTER what values did you load ino the new Nav Attribute and how did that link to the hierachies? Also, in RSECADMIN you created hiearchy nodes based on the Nav Attribute but I am confused as to what values you have in the Nav Attr.
I appreciate if you can share your solution from the past in more details.
many thanks
