How to force RGB in Mac OS X
Download the patch-edid.rb script from the forums thread above and put it in your home directory.
Connect only the external monitor(s) in question (I closed my MacBook lid, for example). The script will make override files for any connected monitor.
Type “ruby patch-edid.rb” in Terminal.
A new folder will be created in your home directory. Move it into the “/System/Library/Displays/Overrides” folder. If Finder tells you that you are overwriting an existing folder, consider backing it up first.
Restart your computer, enjoy your monitor.
To undo the changes, either delete the folder you had copied to the Overrides folder (if it didn’t already exist) or replace it with the folder you had backed up.

Using an external display

Whats the highest resolution external display that the eMac can support? Because I wanted to use the external display as a main screen and set the eMac in the floor.
Also, does anyone recommend a widescreen external diplay?

Hi cosmic,
when I was still using my eMac I had it hooked-up to 23" monitor & the rez. on that one was 1440 x ? (don't remember the height). I was surprised that it could do it (that's why I can remember the width).

Mouse skipping problem when external display connnected

I recently purchased a Macbook, and I connect it to a Dell 3008 display using the mini DisplayPort to dual-link DVI adaptor. My issue is that when the Dell is connected and in use, the mouse pointer skips across the screen when I move it, like something is interrupting the input for a very brief period, and it's being interpolated wrongly when the input comes back.
The problem doesn't occur when the external display is disconnected, and it happens with wired USB, wireless USB and wireless Bluetooth mice.
No adjustment of mouse sensitivity options seems to fix it, and the interruption in the pointer movement seems to happen at semi regular intervals of between 5 and 10 seconds apart, although I can't be 100% sure.
Interestingly, it doesn't happen when I connect a lower resolution external display using the same adaptor. So it only happens at 2560x1600. I'm wondering if it's a problem with a hardware accelerated mouse cursor and the NVIDIA graphics driver.
Anyway, it's a real barrier to me using the Macbook, so hopefully someone has a solution.
Thanks!

Same problem here: wireless MS Laser Mouse 6000, either a samsung or LG external display connected via mini adaptor. Have the MS intellipoint drivers installed. It began to happen about a fortnight ago, and seemed to coincide with the Java update 4/Bluetooth Firmware/ Safari update applied on 24/6. This may have been around the time I changed display preference to 'best performance', so could well be a graphics driver issue?
In my case, it tends to happen in certain spots on the screen, and the likelihood of a skip seems to depends on the speed I'm moving the pointer. Faster = more likely.

Phantom external Display

I've started to notice a strange symptom on my MBP 15" 2.0GHz CoreDuo.
I regular switch back and forth from home and office and when I'm in the office I have the MacBook Pro connected to an external Dell 22" display. When at home or traveling it's just the laptop with it's internal LCD.
Lately, whenever I reboot the laptop as a standalone (no external display connected) it starts up thinking that it has an 800x600 resolution external display connected. It always positions that display to the top left of the built-in laptop display. I first discovered it when I was moving up to the Apple menu and the mouse cursor would disappear. When I opened up the Monitor Control Panel, I see the option to Gather Windows as well as the Arrangement Tab. If I click on Arrangement it shows two displays connected with the orientation. I can also see the Detect Displays button which if I click on it a few times it eventually sees that there is not an external display and moves it back to the normal mode.
I even checked the System Profiler in this state, and it also thinks that there is an external display connected until I go through the sequence to clear the reference to the external display.
I recently sent the MBP back for a fan repair where they replaced the motherboard as well (unknown reason). Has anyone else seen anything like this? I'm wondering if there is something obvious I'm missing before I call AppleCare on it.

Problem with resolution of external display

Hi,
I am trying to use external display with my Unibody Aluminium Macbook Pro (NVIDIA GeForce 9400M, 2.26Gh, snow leopard). Cable setting I use is quite complicated as it is: macbook: minidisplay port>hdmi> DVI D : display. Display is LG Flatron W2242T (4:3).
So I hooked everything up and macbook detected display without any problem. The problem arises when it comes to resolution. Maximum resolution I can set (and in fact the only except 800xsomething) is 1152x870 and not only it is to low, but also it does not respect 4:3 ratio so it looks quite bad. So bad, that i cant really work on a setup like that. When I try to change resolution to any other, Display goes black. I tried using some apps, but they dont really work.
What can be the problem here? Is it connection?
I would appreciate any help.

And once you've cut thru the clutter of cables and adapters, remember the max you will be able to push the Flatron is its "native resolution", that happens to be:
Screen Size
22"
Screen Type
TFT LCD
Wide Screen
Yes
Brightness
300cd/m²
Contrast Ratio
8000:1
Viewing Angle
(Horizontal/Vertial)
160/160
Response Time
5ms
Resolution
1680X1050
Supported Colours
16.7M Colours
(data taken from LG's product page)
If you happen to have a late model MBP with the widescreen option, the Mac and the display will be on a 1:1 ratio, both are the same. Else, if you have a regular MBP, the monitor has more resolution than the Mac (1440x900) and distortion will occur if you do video mirroring.

EXACTLY what cable(s) do I need to connect my MacBook Pro (early 2011) to an external display with a 2560x1440 resolution?

I am trying to connect my MacBook Pro (early 2011 w/ Intel HD 3000/ 384Mb) to an external display with a 2560x1440 resolution. Specifically, what cable/connections do I need to display at this resolution? I cannot get the display to work using a "Thunderbolt to HDMI" or a "Thunderbolt to DVI" connector. Note: I used both older and newer (uni-directional) HDMI cables on the first config, and a Dual-link DVI cable on the second config. Apple specs state this is possible ( support.apple.com/kb/SP619 ), but I am at a loss as to how this can be done. Thanks in advance for the help!

You use a Mini DisplayPort to either HDMI or dual-link DVI adapter. If that component doesn't work, something's wrong with either the cable or something else in the connection.

Macbookpro doesn't recognize max resolution of an external display

hi
i have a macbook pro 7.1
i just bought an external display, LG IPS237L-BN 23 inch Full HD IPS LED Widescreen Monitor (250 cd/m2, 1920 x 1080, 5000000:1, D-sub, HDMI)
my mac doesn't seem to recognize the resolution. after some internet research, it seems to be a common problem, except that all i've seen are some solutions via dvi port. My monitor has only 2 hdmi (from what i can tell, i'm no expert), and some "d-sub", whatever that is.
I've had a small mdp adapter, connecting via hdmi-to-hdmi cable to the monitor, but to no success. I thought it may be the prob with the adapter as i've bought it a while back, so i went and got a mdp-to-hdmi cable (this one: http://www.amazon.co.uk/gp/product/B00675Q2UY/ref=oh_details_o01_s00_i00?ie=UTF8 &psc=1), but again, the max resolution in display preferences is 1600x900, and all is blurred, while my main purpose is photo and video work.
Any advice?

Hi
did you found the solution?
I have MBP 7.1 too, and just bought an LG 22" FullHD monitor, but i got the same problem.
I can set the resolution to 1920x1080 but the screnn on external display is not like fullHD, and its not as colorful as it can be(I tried the monitor with my windows laptop, and the colors and resolution was ok).
I'm using Mini DisplayPort to VGA adapter to connect them.
Help me if you can!
Many thanks,

Can i choose the resolution of my external display for when the lid is closed when my lid is open

When I close the lid of my MacBook Pro for an external display apple chooses a resolution that isn't compatible with my display can I choose the resolution when the lid is open in any way of my external display for the mode when the lid is closed?

Hi there, I had a similar problem and was unable to resolve it. I spent about an hour on the phone with a very helpful AppleCare rep who was also completely stuck. It would seem that the only solution is to choose a setting with trial and error while the lid is closed.
My MacBook ended up getting stuck on a closed-lid reoslution that wasn't supported, so I had to do a screen-share with another device to see what the video card was sending to the external display and change it back that way.

How to change external display resolution WITHOUT clicking "CONFIRM"?

I have a somewhat unusual situation. My MacBook laptop is actually now a ModBook (a pen-tablet computer), and as such I no longer have a trackpad attached to it. All of my inputs are via the stylus, tapping directly on the built-in display.
This works perfectly fine, except when I need to give presentations on an LCD projector (which is quite often lately). I like to use the projector as an external monitor, so that I can run the Keynote presentation on it while using my laptop screen as the presenter's display, with the upcoming slide, etc. If the projector doesn't give me an ideal native display option (sometimes, the aspect ratio for the 3 or 4 resolutions available in the Displays drop-down in the menubar turn out to be stretched or squeezed), then I, naturally, have to open the Display System Preferences and try out different resolutions.
The problem is, since my stylus only interacts by clicking directly on the built-in-display, I have no way of moving the cursor over to the external display when the dialog box with the "Click here to confirm change/You have 15 seconds..." message appears. So I can never click it ... so I can never confirm the new settings.
The workarounds I've used so far are:
- Mirror displays (not ideal, as I need the presenter preview of the next slide)
- borrow a mouse from someone (usually from a Windows desktop, frankly) and plug that in to briefly mouse over and click the confirm button
I'd love to find a software workaround that allows me to NOT mirror displays and also doesn't require me to carry around a mouse all the time (my laptop bag is already overstuffed...).
Thanks.

Conflicting information about external display resolution - please help!

I have a MacBook Pro (15-inch, Mid 2009) with the non-reflective screen, Mini Display Port and NVIDIA GeForce 9400M Graphics processor.
According to these technical specifications (http://support.apple.com/kb/SP544), the built-in NVIDIA GeForce 9400M Graphics processor supports full native resolution on the built-in display and up to 2560 by 1600 pixels on an external display.
Armed with this information, I just purchased a shiny, new DELL U2711 (http://accessories.us.dell.com/sna/productdetail.aspx?c=us&cs=04&l=en&s=bsd&sku= 224-8284&redirect=1) external display which has a resolution of 2560 x 1440. Unfortunately, all I can get out of it is 1920 x 1080 (This is the maximum resolution I can select in the monitors system preferences panel.)
So Apple tells me this graphics card supports 2560 x 1600, but I also contacted NVIDIA directly who told me that this particular card's maximum resolution is 1920 x 1080.
Somebody has to be wrong. Is this monitor supported? Am I doing something wrong? Do I need to send this monitor back and buy a smaller display?
Any advice would be greatly appreciated.
O

Well - seeing as nobody could provide any help on this, I'll post the answer in case anybody else has the same problem.
It turns out that the monitor's resolution IS supported by the NVIDIA GeForce 9400M, so the information NVIDIA gave me was wrong.
The issue was the adaptor.
A regular Mini Display > DVI adaptor can only handle a resolution of 1920 x 1080. Turns out I needed a Mini Display > DUAL LINK DVI Adapter, which is a combination of USB and DVI which provides the required resolution of 2560 x 1600.

Leopard "Forgets" External Display Resolution

I have a 17" MacBook Pro C2D (Oct 2006 revision) that I use at work with an external display (Dell E197FP) that is connected to the laptop via the DVI-to-VGA adaptor. The Dell has a native display resolution of 1280*1024 @60Hz and this is set via the System Preference's Display panel. The problem is that quite often when I connect the display in the morning OS X (10.5.6, at present) "forgets" the resolution that has been set and reverts back to its default for the display, which is 1152*864 @75Hz. It is baffling to me that it keeps forgetting the selected resolution for the display, despite recognising it, and that it selects such an odd resolution as a default. This happens about once per week at the moment.
Does anyone have an idea what is causing this and how I can stop OS X from being so forgetful?

Are you getting one to extend your desktop? I don't, I use my MacBook with the screen off using my external only with a keyboard and mouse plugged in. I run my Late 2008 2.1GHz MacBook with a GMA X3100 using a 23" Samsung wide ratio no problem in 1680x1050. It is high resolution. Make sure you click "mirror" in Display Prefs. Be certain that you don't simply boot to both because the external will appear grainy and only be putting out the native 1280 X 800 13" MacBook resolution on the new big LCD. There are many different ways to achieve this. With the LCD on and hooked to the MacBook, turn the MacBook on then quickly close lid after the chime. Give it some time. After it boots to the external, I open the lid to provide proper airflow, some may argue it's not needed.

External display resolution

I have Dell up2414q monitor which is capable of displaying up to 3840 x 2160. But when I connect my 11-inch Macbook Air (the latest 2014 model), which is capable of 2560 x 1600, shows only 1920 x 1080. This is the highest resolution listed in display setting.
I'm using Display Port cable and enabled Display Port 1.2 setting on the monitor. I went to Apple Store and asked, but they had no idea what was wrong. My OS is 10.9.3.

External Display Resolution Issue...

I have a Mid-2012 MPB running Mavericks. Recently, I've tried connecting 2 different external display's to the MBP via an Apple Thunderbolt to VGA adaptor. I can't get the resolution of the connected displays to go above 800 x 600, and it looks awful.
The first screen is a Samsung SyncMaster T260HD with a native res of 1920 x 1200, and the other is a Samsung SyncMaster 933HD, with a native res of 1366 x 768. I plug them into my Windows box via a VGA cable, and it will drive each display at it's native res just fine. So what have I missed to get the MBP to do this???
Thanks in advance. :-)

My MBP has Thunderbolt and I have a mini displayport to DVI adapter. This is connected to the DVI port in the display.
That option key selection did not increase the alternative resolutions available.
I did reset PRAM according to a advise hee in the community. That did not help either.

External display resolution changes after returning from display sleep

I often use an external display as a second screen with my Macbook Pro (OS X 10.8.2) However, when I return to the computer after the display has gone to sleep, the external display resolution changes when the display reappears. Then I have to go into System Preferences > Display and "Detect Displays" in order to return the external display to the proper resolution.
Does anybody know of a way for me to avoid having to do this every time my display sleeps?
Thank you,
Adam

I have the exact same problem.
I found the key combination ⌘ alt F2 also restores the proper resolution on both displays, however it's still a bit annoying

External display incorrect resolution when MBP lid is closed

Hi,
I've just bought a 24" Samsung monitor for use with my 2011 MBP. The optimum resolution for the monitor is 1920 x 1080. I ahave it hooked up through a minidisplay to vga adapter. When I have this resolution selected in extended display mode it works fine, however when I close the lid and run the monitor with the same resolution as the main display, the image gets squashed and the screen flickers, I can also see faint lines in the background and the display is not centred, leaving black gaps on either side of the screen.
The frustrating thing is it was originally running fine before I temporarily changed the resolution in display preferences when in closed lid mode. Is there any kind of fix for this?? I know it's not the monitor's fault because it's displaying the correct resolution when in extended desktop and on other systems.
Any help would be greatly appreciated!
Chris

What else can I try??
Any bossy third party apps trying to control things?
Run Apple Hardware Test, and/or a trip to the "genius" bar.
No thrid party apps have access to my display prefs as far as I know. And the hardware test did not indicate that anyhting was wrong. I would like to leave the "Genius" bar as a last resort, they weren't much help last time...
Ok so moving the menu bar is allowing me to use the external as native desktop, but this doesn't fix the resolution problem when I close the lid even though the resolution in display prefs is set the same. Is it possible then to tell the mbp not to sleep when I close the lid?? I know you can do this in windows. Please note that I am still using Snow Leopard v10.6.8
