How to keep iMac screen black while keeping secondary monitor running for visual experiments in Matlab

Hi,
I'm trying to run a visual experiment using PsychToolbox in Matlab.
I've attached a secondary monitor to my iMac for this purpose and I'm having difficulties trying to
'black out' the iMac screen.
I need the secondary monitor to run at a refresh rate of 120Hz and at linearised luminance (did this for my secondary monitor),
so I can't really use my iMac screen. However, i need my iMac screen to be darken out because I'm doing a vision experiment.
I tried dimming my iMac screen but it doesn't go completely dark. I tried Ctrl+Shift+Eject (or was it Command) but it will darken both
monitors. I also tried mirroring, but it doesn't seem to work too.
I'm really stuck and any ideas will be greatly appreciated!
shui
NB:I'm using OS X Version 10.8.3.

I do not know the details of your experiment, but creating a black monitor is not difficult. For example a completely black page, e.g. in Power Point, set to fill the screen?
The advantage of doing this with PP is that you can move in to or out of the black page with just the space bar. You can set up your monitors so PP is displayed on just one monitor.

Can i use imac screen with another comp?

hi all - can i use my imac screen with my g4 powermac?
I like to run it but my old monitor is big and ugly - be nice to feed into my sexy g5 imac screen
advice - as ever - appreciated
dc/uk

I don't think so. You could use Remote Desktop, but it would be slow and annoying, and it costs more than a decent 19" ViewSonic.
But that would be nice. I'd love to run even my iMac G4 into my wife's iMac G5 screen.

External Monitor with iTunes - iMac screen goes black

I have an iMac with iTunes 7.7/Leopard and an external VGA monitor (I use the standard Apple mini-DVI to VGA converter) then I use the external monitor to watch video from my iTunes library.
All works well - I have my desktop spread over both monitors, I fire up a movie from iTunes, move the video window across to the external monitor and everything is good - I can watch the video on the external monitor whilst continuing to work on my Mac - the iMac screen displays the Mac desktop as normal.
However, if I put the movie into fullscreen mode (view -> fullscreen on the iTunes menu), the external monitor displays the movie in fullscreen mode as it should, however the iMac monitor goes black.
The only way to fix this is to exit fullscreen mode and go back to one of the view options (rg fit to screen).
Any ideas how I can have my external monitor in fullscreen mode and have my desktop back?
Many thanks

Any external monitors as good as imac screen for text?

hi all.
this is my first mac. it's a new 21.5inch imac with a 2.7ghz i5 proc running OS X 10.7.3 and 12 Gigs of RAM (8 Gigs from crucial for $50, who can resist?)
i've got it hooked up to an external samsung syncmaster B2330 running in 1920x1080, which is this monitor's native resolution. works fine. it's hooked up via the dvi port on the screen via the mini-displayport to dvi adapter for the mac. i switch this monitor to the vga port when i want to use it as my pc monitor also running at 1920x1080. there is a source button on the monitor. very convenient.
the issue is that they text on this screen when coming from the mac is not as clear was when coming from the pc despite the fact that the vga port provides much less bandwidth than the dvi port the mac uses. i've read that the mac and the pc display text on screen using different methods. my pc uses an nvidia display graphics card. i believe mac use ati based hardware.
there appears to be much more interpolation when displaying text from the mac. perhaps this is a text size issue i'm not sure. either way i read a lot on this monitor and need it to be as good as possible for that purpose.
so the question is, does anyone have experience with an external monitor that is as good as the imac screen for text display. i can't use the thuderbolt display or a cinema display since they don't switch to different ports allowing my to use a single external monitor for two machines. i'm willing to spend up if there is a reason to do so. i'm on these computers a lot. i work from home with some regularity and my job is all about reading.
any help is appreciated.
best, c

I have an dell 24" lcd as 2ed monitor and text look as clear as the imacs screen
but it having a t-nfilm lcd panel vs. the imacs ips panel the colour and contast look worse
but text look as clear
and it look the same when I boot up in win7 using bootcamp

Mirrored my imac temporarily to my video projector now can't get imac screen back to standard viewing (shows as if a side monitor is added)

I recently mirrored my imac to project some videos. I now want to return my imac to regular use and standard screen presentation but find it remains in the mode as if i have an external monitor connected to it with the monitor on the right side. My imac screen only shows roughly 2/3 of the image, as if there is another monitor connected to the right side. I've disconnected the projector, tried turning mirroring off, searching for displays, putting the computer to sleep. I keep getting this same visual set up.
Thanks for any assistance.

Thank you Malcolm for the response. An excellent idea which I hadn't tried.
I actually had zapped the PRAM several times (and even reset PMU) but did not think to do it with the DVI->VGA adaptor removed, so I just tried this. Unfortunately this didn't solve it. After removing the DVI-> VGA adaptor from port 2 and zapping PRAM (twice), I now am getting an "unsupported input" message on the monitor connected to Port 1 with the DVI->VGA adaptor still removed from port 2. So if anything this state is worse.
This is very strange--because when I put the DVI adaptor back on port 2, the situation returns to where it was before as described. After a hardware reboot I have the aqua screen with missing login window again. It seems zapping the PRAM did not do it here. It also seems this DVI->VGA adaptor is definitely having an effect on the situation. Why would connecting a DVI-VGA adaptor on port two cause port one to regain function and why would removing it cause port 2 to go dead essentially?
At any rate, I am still unable to use the computer...

IMac screen cleaning product advice.

Hi,
I note the Apple Store (device care) offers Techlink products but not specifically for a iMack screen.
What is safe and recommended to keep my iMac screen clean.
Cheers.

I always follow Apple's advice on how to clean a display, they describe it in How to clean Apple products

Photosmart C6280 won't print after trying to clear library/startupitems error

I have had a Library/Startupitems error ever since updating my HP software a couple of years ago. In trying to finally resolve this issue myself, the HP website suggested removing and reinstalling the software. There is no active link within the HP support pages for a download. I found a C6200 series driver online, which I've installed, but now I cannot print anything but a test page, and I still have the Library/Startupitems error. As it is, I cannot even find that file at all to fix the error.
This question was solved.
View Solution.

Hi @Eric_V67
Since the C6280 doesn't have full feature software and drivers, I can't image the error is stemming from the printer. I can however, provide you with instructions to remove ALL HP software including the HP driver that was provided from the apple software update.
If I understand one of your previous messages, it looks like perhaps you had this printer installed previously and then upgraded the Mac OS. If this is the case, then old software that was previously compatible could be the root cause.
Once the HP software and drivers are removed, you can restart the computer and see if the error persists. The final step would then to be reinstall the Apple software update.
Follow the instructions below. I apologize in advanced this is not a fun task! I will try to make it easy to follow. Some of the files described in the following steps may not be found, if you can't find one of the files or folders on your computer, don't be alarmed.

Attention: HPIO Trap Monitor wake issues on Leopard

Guys, I've never had any sleep issues with my Intel iMac before; but it seems like the latest 10.5 updates are NOT compatible with the HPIO Trap Monitor, which is part of the software package installed for HP all-in-one printers on Macs...
In 2 or 3 occasions during the last couple of months, I wasn't able to wake my iMac from sleep, having to resort to a hard reboot. It's nothing with 10.5.7, because this ALSO happened with 10.5.6.
After some analysis of console messages, I discovered the following:
Process: HPIO Trap Monitor [97]

My question: my printer works fine so far, but I am afraid this driver or specific process is not compatible anymore with Leopard...what happens if I erase it from my system? Thanks in advance!

Reinstall the latest HP software. I have no such crashes with my Photosmart 4280 AIO attached to my iMac. Version 2.6.0 runs without issues.

IMac screen: the light colors are gone to white

iMac screen: the light colors are gone to white. Not only in my windows, also in all browsers, etc. Must be a software problem, if I start up from an external disk it's OK. Possible a bad file in my User library but which one?? I did fresh install Snow Leopard, then it was OK again, but when I started some applications it went wrong again. Has anyone ever seen this?? I went to the Apple store and they could not help :-(

Screenshots do not show what you are actually seeing on the monitor.
Try holding the (Control Command Alt) keys and pressing the (Comma) key several times.
Alternately go to: Apple / System Preferences / Universal Access and in the Display section make sure that Enhance contrast: is set to normal.
