MacBook Pro :: Using External Displays And Graphics Switching?

Jun 7, 2010

I just plugged in my Cinema Display to my MBP for the first time, and for a while couldn't figure out why the heck the computer wasn't recognizing it (though maybe I'd gotten a bad MDP/DVI adaptor).

Then I'd noticed I'd set it via gfxCardStatus to use Intel graphics only. I released it to Dynamic -- and voila! Display recognized. Interestingly, it now also will not accept being set back to Intel only with the monitor connected.

Why Does MacBook Pro Have Graphics Switching

Apr 10, 2012

I was looking through tech specs of the 15 and 17 inch macbook pros and comparing them to iMacs, so i was wondering why they did that? Is the graphics better on the macbook pro?

MacBook Pro :: Graphics Switching In Windows?

Sep 7, 2010

The title is pretty simple, and self explanatory. Will the HD Graphics/330M combo, or the 9400M/9600M GT ever be able to switch back and forth in Windows? And regardless of if it's possible, what is the limitation, drivers, other software, or a physical hardware limitation? It would be a nice way to get more battery life out of Bootcamp.

MacBook Pro :: Graphics Card Not Switching?

Feb 5, 2012

I have a MacBook Pro 15" 2.66 GHz Intel Core i7 (Mid-2010). I have auto graphics  switching turned on in the Energy Saver prefs. But it never switches. It stays on the nVidia card all the time. 

I have tried switching to Text Edit, Mail, BBEdit, and other non-graphics intensive apps. It stays on nVidia. It stays on nVidia even when I unplug and use battery power. 

I can manually change it to Intel, and it works fine. When I change it back to auto switching, it stays on nVidia continuously.

MacBook Pro :: Not Switching To Discrete (AMD) Graphics

Jun 25, 2014

MPBr, 15", Early 2013 with dual graphics (Intel HD Graphics and AMD Radeon)

Running Maverics 10.9.3 

What is happening:

1. Machine doesn't switch to AMD graphics no matter whatever app is running. In activity monitor even if some apps say "Requires High Perf GPU", the graphics card being used is still "Integrated".

2. Connecting to an external display via thunderbolt or HDMI doesn't work (external display doesn't turn on) either as it required discrete graphics too.

3. After a reboot (at what time I believe machine tries to use discrete graphics card), the display is always blank. Even the Apple logo on back of lid is turned off. Only way to get the display back is to close the lid and open it after 10 ~ 15 seconds at which time it probably switch back to integrated and comes alive. 

What I have tried:

1. Reset PRAM.
2. Reset SMC.
3. Tried gfxCardStatus [URL] to no avail. If I manually switch to discrete card, gfxCardStatus checkmark say it has switched, but it doesn't.
4. Tried booting into hardware diagnosis (pressing D while booting) but was unable to get the screen turned on to proceed.

MacBook Pro :: Auto Graphics Switching - Delay?

Nov 4, 2010

Does anybody experience any delays with the auto graphics switching on the late 2010 MBPs? I mean serious delays? Mine seems to be very slow at making the switch. Say if I open a PDF that has a load of images in and start to scroll at high speed to scan the document, everything becomes very stuttery. Then, after a while (very random in how long it takes) everything starts to get smoother, when I assume the NVIDIA kicks in. I thought this was meant to be more-or-less instantaneous?

MacBook Pro :: Switching Graphics Cards Without Logout Possible?

Aug 20, 2009

My primary concern is whether or not uMBP users will ever be able to switch the graphics cards without logging out every time? I remember hearing that it was a software issue, does that mean that it might be supported in Snow Leopard?

MacBook Pro :: Graphics Switching Without Restarting Windowserver?

Apr 14, 2010

Obviously the new Macbook Pros do not require a reboot to switch between graphics cards while the previous generation, the one which had two graphics cards made by the same company, requires a login/logout. The case made for the necessity of this login/logout has been the need for the WindowServer process to be relaunched, and to overcome this, WindowServer would need to be rewritten. Obviously that didn't happen. Further, if random Nvidia insiders are to be believed, this wasn't done using Optimus technology by Nvidia, but rather by Apple... so. How do you suppose they pulled that off?

OS X :: Switching Between Primary And Secondary Displays

Aug 15, 2009

I have a Macbook which is setup with an external display. At the moment the external display is set to "the primary" screen and the Macbook the second. I know in order to change the Macbook screen to the "primary" screen I have to go to System Preferences >> Displays >> Arrangements. But is there a way of automating the process so I can easily switch between the two (say with a icon in the dock). I have had a look through Automator, but nothing seems to fit the bill.

MacBook Pro :: Graphics Not Switching To Intel Hard Drive

Jan 6, 2011

I purchased a Macbook Pro 15" i7 last month, and since doing the migration (using the migration utility) from my old black macbook my graphics are stuck on the Nvidia graphics and is not switching to the Intel HD graphics. This is eating battery power like no tomorrow.

MacBook Pro :: Why Does The Automatic Graphics Switching Turn Itself Back On

Jun 21, 2012

I have a late-2010 Macbook Pro 15" and have been having issues with gaming.  Specifically, the games will freeze the system requiring a reboot.  After reading further, I learned about the "Automatic Graphics Switching" mode under "Energy Saver" in the System Preferences screen.  Upon disabling this setting, and locking the preferences, the games are still freezing.   

I have not re-enabled this setting but when I check the settings again it is enabled.  Seemingly, the OS is changing the "Automatic Graphics Switching" on its own.

MacBook Pro :: How To Avoid Switching To Integrated Graphics Card

Jun 27, 2012

See the new Macbook Pro that I recently got has two graphics cards. One, the integrated, standard issue Intel HD4000 and the other one, a Nvidea GT650M. Personally, I was thrilled to learn this. However, my Macbook Pro seems to switch in between these two and I really don't want it to do that. I would rather just make the GT 650M the main graphics card and avoid using the integrated graphics.

MacBook Pro :: Automatic Graphics Chips Switching - Extended Battery Life

Apr 13, 2010

the new machines will switch between graphics chips. all very nice (at last), but my 15" MBP 2.8 doesn't and it's a real pain for me as I often go between apps than need the extra speed and then back to e.g. Word, and could really do with the extended battery life (I have the old style battery pack) any news if the older graphics systems can be worked to switch on the fly...i.e. without having to logout and shut down all the open apps, and work?

MacBook Pro :: Screen Flickers Black For Short Moment On Switching Graphics

May 9, 2010

I just got a new MBP i7, and whenever the graphics switch from the Nvidia 330m chip to the Intel chip, the screen "flickers" black for a short moment before reappearing. Can anyone with a new MBP comment on this behavior? It doesn't happen on the switch from Intel->Nvidia, just the other way around.

MacBook Pro :: Stop Automatic Graphics Switching Setting Automatically Reverting

Jun 25, 2012

Macbook Pro 15" Mid 2010

OS X 10.7.4 

I have a recurring problem where my screen (built in or external monitor/projector) will just go blank at random times. It is an unrecoverable situation and I have to do a hard power reset to get working again.

After testing several theories without success I struck upon one that showed promise. The blanking tended to occur when I was in Lion Fullscreen mode, or using a gesture to start expose - so I figured maybe it was a graphics switching issue.

So I went into System Preferences and disabled 'Automatic graphics switching'. I then ran trouble free for several days (I was typically crashing 1-2 times a day)

Then several days later it happened again and I thought I was back to square one. However, a colleague suggested I check the graphic switching setting to see if something had changed it back, and sure enough it was re-enabled.

Now I find myself in a constant battle with the system to keep disabling the 'Automatic graphics switrhing' in System Preferences.

I have tried setting it and locking it, but sooner or later it reverts. I need to know if it is possible to force it to stay disabled.

Mac Pro :: Finding Displays And Graphics Card Options For Matrox M9188

Nov 12, 2009

ven an everyday user may consider such a card if the price is within budget which currently isn't. It isn't targeted at gamers who need every ounce of performance though.

It appears to be geared towards Apple since it debuted with onboard DisplayPorts. However, it should be noted on their specs page that the system requirements currently do not list any version of Mac OSes. Matrox do list Linux support though. Do note that they didn't leave out regular DVI users. Direct Link for more details on the specs.

MacBook Pro :: Its Support For Two External Displays?

Jun 21, 2012

I keep seeing articles since yesterday stating that the new MBP retina display supports 3 external monitors and the new Macbook Air supports two (through just one ThB port?) but how come no one says anything about the new regular MBP's support? If the Air supports two isn't the regular MBP also supposed to be able to work with two external monitors?

MacBook Pro :: How Many External Displays Does The Retina Support

Jun 14, 2012

How many external displays dose the Retina MBP support? I have herd conflicting information about this, an apple store employee told me that it could support 2 thunderbolt displays while simultaneously running a HDMI connected display (witch would be awesome if true) but I am extremely skeptical, that seems like to much for one GPU.

MacBook :: Safari 5 Kills Flash Support On External Displays?

Aug 12, 2010

I have a blackbook running 10.6.4 with a GMA 950 that I use dual monitors with. If I use the extended desktop mode, and drag a safari window with a flash player onto the external display it will freeze and become unusuable (can't interact with it). The audio will still play through the speakers, and dragging the window back onto the main display brings back the flash functionality. This is a fairly new problem, it never used to happen before.

MacBook Pro :: Late 2011 No Longer Connects To VGA External Displays?

Apr 21, 2012

My late 2011 MBP (lion 10.7.3) used to connect to external displays through a VGA cable.  It has stopped doing so since recently and I am trying to find out why, and how to fix it.  The only changes I've applied to the system are (1) connect to a Thunderbolt display and (2) installed gfxCardStatus.  The MBP and Thunderbolt display work flawlessly together, with network, USB, and firewire connections operating.  gfxCardStatus has noticably increased my battery life (so I recommend it) and I'm aware that it needs to be in dynamic or dedicated GPU mode for external displays.  The VGA external displays do not work when gfxCardStatus is running in either dynamic or dedicated mode, or when I disable gfxCardStatus completely so that it does not show on the process list.

MacBook Pro :: How To Connect Two External Displays That Are Not Mirrored And Turn Off Retina Display

Dec 9, 2014

I have two questions:

1.  Is it possible to use two external displays either mirrored or not and turn off the retina display, and if so how it is done?

2.  Is it possible to close the MBP and use an external keyboard while using two external displays?

I am using a music production DAW Persons Studio One-2 Pro and it would be great to be able to have this type of a setup.

OS X :: How Do Achieve 2 External Displays

Apr 5, 2010

I currently have a 15inch MacBook Pro with final cut studio, I use an external HD monitor for my main editing and the MBPs display for secondary. I am running out of screen real-estate for my secondary and want to get a 3rd monitor. The only problem is that there is not way to upgrade the graphic cards in the MBP. My question is: How can i have a total of 3 displays all displaying different images(ie. not mirrored).
