Mac Monitor settings, no external monitor

I'm a few months away from buying an external monitor and my videos are looking much different on a TV than on my 24" mac monitor. I have a NVIDIA GeForce 8800 GT graphic cards. How would you all suggest I get as much color/ brightness accuracy as possible when editing with just a Mac monitor? Where should my brightness be?
Thanks!

Your Mac's computer monitor will never be able to accurately reproduce NTSC colors and gamma.
However, you could use a Matrox MXO.

Apply MacBook display settings to external monitor

Hi. The display on MacBooks and other Macs is beautiful, and I wish I can bring those display and color settings to my external monitor, because no matter how much I calibrate using the one under system preferences or adjust the setting directly on the monitor itself, it does look as nice as it does on my MacBook Air to which the display is connected. I can see all the figues in System Preferences -> Displays -> Color tab -> Open Profile, of both MacBook Air and the external monitor, but is there a way I can manually change those figures of the external monitor so that they are same as those of MacBook Air?
Thanks.

Yeah, I've changed the Display Profile of my HDTV (connected as a monitor).
If you go into System Preferences > Displays then click Gather Displays and click on the Color Tab for your monitor, deselect "Show profiles for this display only." You should be able to chose the same Display Profile for you monitor as your Mac.

HT6065 I have a problem with my Mac book pro, my external monitor is not working and i need it to do my business. Please can someone help me with this. I am running windows 8 on parallels.

Since I have up dated my Macbook pro, my external monitor does not work. Who can help me

It was working untill i did the update

Dual monitor (w/laptop): external monitor is blank.

Hi! just installed arch for the first time a day ago. Right now what I'm working on is on getting my second monitor running (mostly for development purposes... and movies ^__^).
I'm using Arch64 with the open ATI driver and KDE. Whenever I connect the external monitor, the monitor seems to detect a connection occurred (the "check video cable" message disappears when I connect it and comes back when I disconnect it), and so does KDE. When I open my display settings, it tells me a new monitor was connected and asks me if I want to configure it.
Then I choose to configure and use the two monitors giving the following screens (right now I'm at college testing with monitors in there, thus the low resolution, but behavior seems to be exactly the same):
(EDIT: resized. In case of wishing to read full images, just take the "resized/" out of the URI)
However pretty the full screenshot looks like (... I just mean that even if it looks like the second monitor is working), the monitor remains blank.
Using arandr (xrandr's gui), it is exactly the same result. I might be doing something wrong (almost certainly I am ) (EDIT: decided it was a good idea to show what I did with xrandr).
In /home/<myuser>/.xinitrc my file looks like this:
#!/bin/sh
# ~/.xinitrc
# Executed by startx (run your window manager from here)
xrandr --output VGA-0 --mode 1440x900 --pos 1600x0 --rotate normal --output LVDS --mode 1600x900 --pos 0x0 --rotate normal --output HDMI-0 --off
if [ -d /etc/X11/xinit/xinitrc.d ]; then
for f in /etc/X11/xinit/xinitrc.d/*; do
[ -x "$f" ] && . "$f"
done
unset f
fi
exec ck-launch-session startkde
# exec gnome-session
# exec startkde
# exec startxfce4
# ...or the Window Manager of your choice
The laptop's model is Toshiba Satellite L775d. I'm not sure what other information should be required in this situation, but I will be loving to give anything that isn't compromising
Thank you!
(PS: so far Arch has treated me nicely let's see for how long)

I wondered the same. I initially only used KDE for it (that's how it worked in other distros, but I'm guessing Fedora and Kubuntu have way more stuff on top). I moved to xrandr later after searching for options and I did select "Ignore" when KDE asked me to configure and just went ahead with xrandr. The same still happens.
Thanks, I hope I gave the right information.
EDIT: Adding some extra information. I tried rebooting with the CRT cable connected. When the kernel initiated its loading, the messages only appeared on the external monitor. It was afterwards (it was pretty quick, but I will assume it was when radeon's modeset hit) that the external monitor went blank again and, in that situation, the laptop's monitor went blank (so none of the two monitors worked... and I was so hopeful!)

Monitoring via 2nd / external monitor

Is there a way to have playback to a second / external monitor?
It seems like an obvious feature for an on-set tool, but I can't seem to find it. I have one monitor facing me with the main program controls, and a second monitor which would face the client / director and just show the video that is either being captured or played back. It would be similar in concept to the playback settings in Premiere, where you can have it use a video overlay to take over another monitor or external DV device to make it a fullscreen playback feed.
I also tried working around this by using Premiere's capture for the same effect. No dice. Premiere only allows it in timeline playback, not capture.
Anyone?
Thanks very much in advance.

OnLocation CS4 does not support sending video out to a second monitor. You're far from the first to request it, so rest assured that that capability is on our radar. I'll add a vote for you.

Touch on non-primary external monitor controlling primary external monitor

SP3i5 connected to two external touch monitors (AcerT232HLs) via minidisplay on dock to hdmi on monitor2 and minidsply to hdmi on monitor3 and usb3s from dock to each monitor. SP3 is monitor1. Displays work fine. Touch works fine.
HOWEVER, touch on monitor2 control monitor3 display. monitor3 is set as the primary monitor. I get that this is NOT a bug since each monitor is in effect two device (display and touch) AND since most touch input devices WOULD want to control
the primary display.
So either there is a setting somewhere to explicitly redirect the touch on monitor2 away from the primary and TO display of monitor2 or there is a driver issue.
In W8.1 I believe there was a setting as part of the 'touch tablet' settings where you would monitor by monitor go through a click process to say that the touch should control the display on its own monitor. I can't find that in w10 (maybe it's all
supposed to happen automatically? or maybe it just hasn't been gotten to yet?)

Yesterday I found the same problem. I disconnected from a Dell Projector and then later that night I noticed that my computer still showed two monitors. I'm still able to connect to an external monitor and it will detect it. However, immediately after disconnect the phantom display is back.
A little annoying because I'm always having application windows open on that phantom display.
Also I noticed that when I plugged into the projector the color was off significantly, as if there was a bad connection. I tried a variety of connectors and connected my laptop to a variety of different external monitors and all of them work flawless except for the Dell Projector. (I didn't try it on another projector because I only have the one.)
My conclusion is somehow when I disconnected from the projector I hadn't fully shut down or gone to sleep or my computer was in the middle of a disconnect when I closed the lid and this interruption as my computer transitioned from 2 displays to 1 created the phantom display. Hope to see a solution to this.
Thanks

IMac bad monitor. Bought external monitor, how do you shut off main?

I am one of the poor unfortnuate masses that have a bad iMac monitor - the one with all the lines going down it. Bad pixels. Sheesh.
I bought a HP 20 external monitor and hooked it up, it's working fine.
QUESTION: Am I able to shut down the main monitor down without affecting the external monitor? If so, how?
No sense in having both monitors working.
As always, thanks in advance!

There is no way to turn off the iMac's monitor, however there is a way to dim it to black like Dave suggests using Shades.

Best rgb and gamma settings for external monitor with mountain lion

Hi,
I'm using an LG LED 22 inch monitor with my MBP mid 2010 via minidisplay to hdmi. on OS X side the settings have been default. On the LED side the settings , if set to preset RGB it tends to fade the whites a lot. when i set to user definied and let the preset rgb be at it is, the colors are quote decent. currently they are on R 50, G 58 and B 59 and Gamma 1. Which is the best RGB and Gamma value for OS X Mountain Lion?

Welcome to the forum.
First off, you need to go and buy a hardware monitor calibrator, such as an OptixXR or similar. This will build a custom monitor profile for your specific screen. Without this starting point you can forget ANY attempt at accurate colour matching.
Never (and I mean never) use a working space such as sRGB or Adobe98 as your monitor profile, that's not what they are designed for. Working spaces control what colours are possible in the image, monitor profiles control how those colours are shown on screen. Aperture uses it's own working space so you don't have to worry about that too much.
To answer the rest far too briefly, I'd suggest setting the proofing profile to sRGB and of course use sRGB for the export preset. The gamma setting you will have to adjust depending on how dark the Lightjet prints look compared to your screen. You will have to do test-strips to start with.
Your images looking crap on flickr on Windows machines is partly because Windows web browsers generally do NO colour correction, and only partly to do with the different gamma.

Mac Book Pro with external monitor?

I have a MBP that I have hooked up to an external keyboard, mouse and monitor. When I am booted to OS X I can see the display on my external screen but when I boot into Windows 7 I have to open the lid on the MBP to get anything on the external display.
How can I get Windows 7 to show up on the external display without having to open the lid on the MBP?

Never mind, I found it.

Mac won't find external monitor

Hi there,
my old Titanium Powerbook connected seemlessly with my Samsung plasma TV with a DVI to HDMI cable.
However, my new Intel iMac, which I have connected with the mini-DVI to DVI adapter and then the DVI to HDMI cable , fails to recognise the TV. I have tried reconnecting several times and also, turning the Mac and the TV on and off at different times. Even restarting the Mac won't help. Searching for displays in Preferences doesn't work either. I can only assume there is something wrong with my connection. Please help.
Cheers

MBP 15" 2007 with internal monitor off, main monitor signal on external monitor

My MBP 15" 2.2 2007 2 MB RAM NVIDIA GeForce 8600 internal monitor has no video after startup. If I connect my Apple Cinema Display to it, the video of the main monitor is on it, and the internal screen stays off. If I hit the "Detect displays" switch, nothing happens. I have tried the following: reset PRAM and NVRAM, reset SMC, repair permissions using Mac OS X Lion Disk Utilities, and Onyx software as well. I have also formatted the MBP and reinstalled MAc OS, and the problem persists. Can anybody help? Many thanks in advance

No problem... happens to all of us.
Glad it was simple - you wouldn't have liked my next few suggestions!!
Thanks for the star...

Trying to view playback on an external monitor

I need help understanding why I can't view my playback correctly.
I've tried what I think is all troubleshooting possibilities.
I am running FW out into an XL2 to a NTSC monitor.
View/External Monitor/All Frames is selected and I have tried an array of different preference settings.
I have tried all things in this thread:

g5 Mac OS X (10.4.7) FCP 4.5

I to am having trouble viewing playback on an external monitor.
I just upgrade from FCP 4 to FCP 5. When I was using FCP 4 I had it set up that all I need was to click on the clip and it would be displayed on the external montior.
In FCP 5 the only setting I can find for external monitor all through firewire.
On my powerbook G4, I want to use the svideo out to an external monitor.
I have gone through at there setting with no luck. Is there any setting that I am missing to get a signal to my external monitor?
What do I need to do to get this fixed?

Yosemite dual external monitors not recognized?

I upgraded my Macbook Air this morning to Yosemite 10.10 from Mavericks. Now, my Mac only recognizes one of my two external monitors. By this I mean that only one of my two external monitors appears in the Arrangement tab of the Display settings dialog box. This setup worked previously under Mavericks though the mouse motion was jerky on the USB monitor. Is this a bug or does Yosemite not support 2 external monitors? The external monitor that works for Yosemite is connected through the DVI port. The one that no longer works is connected through a USB port via an HDMI to USB adapter. I've rebooted my Mac and the monitor several times and tried the second USB port on my Mac. Both monitors are Samsung though they are different models. Suggestions?

Same issue - but I fixed it! I had the same issues with my MBP while running Mavericks. I tried updated to Yosemite (my co-worker runs Yosemite and has no monitor issues) to no avail. It still did not want to acknowledge any external monitors. Finally I did away with the HDMI connections altogether. I bought to DVI to Thunderbolt cords (Cable Matters, Gold Plated) from Amazon and BOOM! Fixed. Both monitors fire right up every time I plug it up.
I know its not a real fix...its still an issue that Apple needs to address, but it seems to be a great way to get around it until they do. Ive been using these cables for a couple of weeks now and still rocking. I hope this helps someone!

No video to second external monitor but recognized by system

When I connect two external monitors(22 inch AOC) using mini display adapters to VGA or USB to VGA adapter from my MacBook Pro (Retina, 15-inch, Late 2013) with an Intel Iris Pro 1536 MB graphics driver and recently updated to OS X Yosemite Ver 10.10, I only have one of the external monitors showing a picture, the other is a black screen. When going to 'Displays' through settings both external monitors are recognized and shown. I can arrange them how I want. When going into 'About this Mac' and selecting 'Displays' both monitors are displayed as active. No matter which port I use and no matter which monitor I switch around it is always the same. One monitor dark and the other working but both always recognized by the system. Any ideas for me? Thanks
