What MacBook model build year and OS X versions are in use with the computer in question?


A Mini would support with its GPU a main display at as high a resolution as the graphic card processor, display, and connection adapters may allow; but a MacBook/Pro/Air, etc would be able to support a second external display based on the graphics support of the supplemental or auxilary card for that outside display. Not necessarily at full resolution.


And, based on specifications, you may need to use a different display adapter &/or cables to attain a higher quality experience with an external/second display. The build specs or technical specifications of the MacBook should tell you the maximum supported resolution of a second display. That may vary, because of feature sets such as Mirroring, Extended desktop, or others. Plus there may be setting options in the preference panel to change the resolution of an external, if the graphics card in the computer allows it.


That is an uneven comparison, in fact none at all.


You may contact an Apple Store to inquire of any

other 'compatible display adapters' for use with MB.

There may be a way to get a better resolution, or

perhaps you may need to get a different display.


Will MacBook Pro 13" (2012) support a 1920x1080?

Based on the following spec:

  • NVIDIA GeForce 320M graphics processor with 256MB of DDR3 SDRAM shared with main memory5
  • Dual display and video mirroring: Simultaneously supports full native resolution on the built-in display and up to 2560 by 1600 pixels on an external display, both at millions of colors
  • iSight camera
  • Mini DisplayPort


..I thought this wouldn't be a problem.

Were you able to see if the instructions in the link provided were able to help you adjust the displays so they'd be equal or close in output? That much of each build year model and OS X version should be similar enough to do this, as the settings have been standard for quite some time in the system preference panel.


Built-in Display13.3-inch (diagonal) LED-backlit glossy widescreen
Resolutions1280 by 800 (native), 1152 by 720, 1024 by 640, and 800 by 500 pixels at 16:10 aspect ratio; 1024 by 768, 800 by 600, and 640 by 480 pixels at 4:3 aspect ratio; 720 by 480 pixels at 3:2 aspect ratio

{info for a MacBook Pro '13-inch, mid 2010' from mactracker.ca}



Graphics CardNVIDIA GeForce 320M
Graphics Memory256 MB of DDR3 SDRAM shared with main memory (Minimum graphics memory usage is 256 MB)
Display Connection1 - Mini DisplayPort (VGA, DVI, or dual-link DVI with adapter)
Display ModesDual display extended and video mirroring
External ResolutionUp to 2560 by 1600 pixels

{if your computer is different than you state, these numbers may vary}


So, the resolution capability is not limited by the MacBook; you may need to acquire the 'dual-link DVI with adapter' after double-checking to see if the display you are using has a similar capability to connect. Note the display modes noted above, and the details of how to use extended and mirroring in the previous link to an ASC discussion; you may be able to tell if you need the 'dual-link DVI w/ adapter' if that doesn't work.


Hopefully this helps.

Good luck & happy computing! 🙂

Well, this does confirm what I thought after research and reading the link I chose to share. However what I didn't know at that time was the specifications of the exact build year of MacBook you have.


So the adapter is a likely necessity,

whether or not the display is. LOL!


Hopefully you can get an adapter at a local source of knowledgeable Apple trained professionals, and ask if they will take the DVI adapter with cable back should it not be an answer, or should it fail to work with the external device you hope to use it with.


You may be able to drag the image around in the system preference> displays panel to see if the on-screen results change, and this may change a bit once you get the better suited adapter.


Good luck & happy computing! 🙂

That's likely due to the higher specs of a more costly MacBook Pro model.


A database download of http://MacTracker (free) covers most information;

a 'serial number lookup' helps determine exactly what build model year,

example: http://www.powerbookmedic.com/identify-mac-serial.php


So the TV does work, nice to know. And via DVI, also on yours.

Good luck & happy computing! 🙂

Now I am having problems with my Avid Mbox 2 sound interface. It is not playing any sound back. I get small clicks and pops here and there. I tried downloading the new driver and that does not change anything.


I upgraded my 2009 mac mini to ios Mavericks, backed it up, and transfered everything to this mbp 2010. The mbox worked fine on the mini even after upgrading to Mavericks. I even tried twice to make sure.


Any knowledge?

There are some drivers for Avid Mbox2 Pro edition (?)

& says some for Mavericks, & were available Jan 2013.


http://avid.force.com/pkb/articles/en_US/Download/Mbox-2-Pro-Drivers?


However I don't really know much about the product

or the difference between the Mbox2 vs Pro, if any...


{The original product came out in about 2006 and used

a FireWire audio interface according to driver site info.}


And then another page goes to other Avid products & drivers, etc.

where they go on to say Mavericks is not supported by those...


Note the Mavericks alert and other later OS X information on the

following page... starts with wording like this:

Important Note: Mac OS X 10.9.1 Mavericks is NOT approved at this time.

I can't say as I have Avid Mbox ^ knowledge of/or where else to look.

One idea may be to revert to an older OS X, maybe have it on an

external hard disk drive & be able to boot from it, to use older Stuff.


Back to the Samsung TV as display, not sure if the 'DVI adapter

and cable' would add High Definition to output final resolution.

Someone at the Apple Sales support or a retail store may know,

but a product specialist for the MacBook Pro should, or a genius.


Sorry to not know more about those things.

Good luck & happy computing! 🙂
