• MacBook 12 "and external monitors - experiences

  That I have not found much info on using a MacBook 12 "with external monitors (but have found problems), I thought I would post my experiences here for the benefit of other researchers:

  MacBook 12 "with Dell u3415w (3440 x 1440) via a USB - C adapter Digital AV Multiport (HDMI):

  VIDEO: Experienced random black screens on the external monitor. After update to El Capitan 10.11.4 version which included an update of the firmware of the adapter, the problem become constant, with the external screen crashing to black seconds nonstop. Switching the HDMI on the MHL port on the monitor completely solved this problem.

  VIDEO: I'm only able to get a resolution of 2560 x 1080 scaling to fill the screen, which is a little fuzzy but fine for office tasks - selection reduced 3440 x 1440 or "best resolution for this monitor" translates into a look, windowed 16:9, with black bars on the right and left. I have not yet found solution to reach ultra-wide 21:9 angle at the native resolution (but would appreciate a).

  VIDEO: Macbook 12 discs easily display 3440 x 1440 for tasks of office such as word processing and surfing. Video full HD YouTube is generally good, but gets now and then a little agitated.

  AUDIO: Holding Option and clicking on the speaker icon in the menu bar show selectable option for the audio output to the device (monitor). On this screen, it seems to be a problem of reception of the signal of the Macbook when another device is connected to another port. In my case, a PC connected to the DisplayPort would be "laundered" the audio signal of Mac but ONLY if the PC has been out audio through external speakers, not the monitor (a lot of trial and error to discover this. When the audio PC sent ONLY to the screen, the monitor then accept the audio signal of the Mac, too. But have an external speaker connected via a cable audio 3.5 mm to the pc mobo (taken minijack) would somehow replace the TWO PC and Mac audio signal to the monitor. Something to do through the DP connection maybe)

  with ASUS PB27Q (2560 x 1440) via an adapter, no problem.

  with ASUS PA328Q more ASUS PB287Q (3840 x 2160 or '4 K') using the same adapter. Cursor extremely lag/Office up to that you enable DP (Displayport) 1.2 through settings on the screen of the monitors. This allows the Macbook to drive a monitor 4K at 30 Hz, which is always a little laggy, but realistic enough to be productive for word processing, surfing, etc. Would not recommend a 4K monitor for Macbook 12 for a really "nice" experience until / unless that 60 Hz is an option.

  Hope someone finds this is useful.

• Portege R600 - how to use the external monitor on the docking automatically

  Hi - I just got a new Portege; R600-102. It's a great machine - very light and fast.

  I connect to a Slim port replicator to the office and I wish I could anchor and automatically use the external monitor without opening the laptop. Can someone point me in the right direction on how to do it? This process has worked well on my recently retired Dell X 300.

  More precisely:
  # I have the laptop closed Portégé and standby mode
  # I anchor in the Slim Port Replicator (SPR)
  # I press the button 'on' on the SPR
  # I see the message "recovery windows" and the bars of the countdown on the external monitor. (So I know it's connected and you can see the external monitor)
  # The laptop turns on but use the laptop screen (private) LCD
  # I have to open it and manually tell it 'out to watch.
  What can be automatically?

  Thanks for the tips.

• Refresh rate of the external monitor (closed macbook) reset

  Hello

  Im very new to OS X, I have a macbook air 13 "that I have it plugged into my external monitor acer, when he was in closed mode (clamshell) I changed frequency by accident and now I can't change this back as the ' entry is not displayed. How can I change the refresh rate of the external monitor when the settings show only if the macbook is closed? As I said, I'm new so I am not very confident through many parameters, any help is appreciated.

  If you have previously enabled "Screen sharing" Preferences-> sharing system then you can use another Mac to control this Mac and change it to one that works remotely.

  You could 'open' the Mac to use its built-in screen and then be able to change the settings of the external monitor.

  You can try to reset the setting by following the steps listed here Re: how to restore the display settings

• MacBook Pro retina 15 inch heats up when it is connected to the external monitor

  Hello

  My problem: When I connect my monitor (LG IPS277L) temperature of my Macbook Pro starts to heat upward. This problem often occurs when I use Facetime.

  I found it really strange because I should have a pretty good Macbook Pro for this.

  MacBook Pro (15 inch, retina, medio 2015)

  Processor: 2.5 GHz Intel Core i7

  Memory: 16 GB 1600 MHz DDR3

  Graphics card: Iris Pro 1536 MB Intel / AMD Radeon R9 M370X

  El Captain 10.11.6 OSX

  I hope that someone recognizes this problem and wants to share their solution.

  When you connect to an external monitor, you use the AMD Chip for graphics (without the external screen, most of the software needs only the graphics engine Intel).  It attracts more power and therefore heats up.  All MacBook Pro for this to some extent.  This should be considered normal.  If the computer is actually overheating, it will stop.

• External monitor flickering Macbook 2016

  I have a Macbook 2016 and an Apple USB - C for Multi AV-HDMI adapter and a LogiLink USB - C for adpater DisplayPort.

  I am using a Dell 3008WFP as an external display monitor (maximum resolution 2560 x 1600 @60 Hz) with my MacBook, but it doesn't seem to work well.

  The monitor will often empty after a short time ('economy' mode) or only occasionally displays a picture and then turns off again. Using a LogiLink USB - C for Displayport is a bit more stable then the adapter Apple, but also often suffers the same problem.

  On a small monitor Samsung 1920 x 1080, the Apple Multi AV adapter seems to work perfectly well, but on the Dell, it is not stable (via HDMI to a resolution of 1920 x 1200, as the Dell only supports supported resolutions higher on DVI or DisplayPort).

  The map is updated latest firmware 2.33. Is there a problem with my MacBook (again)? Or is it a software problem? Is there a work around? Does anyone have a good experience with the MacBook to 2560x1600@60Hz on an external display?

• MacBook pro at 1920px external monitor via hdmi?

  I just got MacBook pro 13-inch retina and the default resolution is 1280px in width, and the maximum value is 1600px.

  If I connect the laptop to an external monitor via HMDI 1920px resolution, the resolution will actually be 1920, max mobile as 1600?

  You can set the external display to the monitor native resolution or HDMI resolution according to your preference.

  Don't use mirror display on external monitor because when you mirror on the screen display resolution is also in reverse. Use extended display mode.

• Why I can't have a decent resolution of my Macbook Air with an external monitor?

  MacBook Air 13 "(early 2014)

  I bought a Samsung S32E590C 32 '' nice monitor but cannot get above 1920 x 1080 @ 60 Hz (1080 p) using Thunderbolt to HDMI. The resolution is so low that I can't use the screen correctly. I'm afraid I won't be able to get a better resolution with my Macbook Air and will have to sell the monitor...

  Suggestions please.

  Hi sansthwaites,

  Welcome to the communities of Apple Support! I'm sorry to hear you're having problems with your MacBook Air and your new view. I'm sure we can help you understand what can happen.

  Based on your model described, it seems that the beginning of 2014 MacBook Air should be able to produce a somewhat higher resolution for a monitor external, as shown here:

  Graphics and video Support

  • Intel HD 5000 graphics card
  • Dual display and copy video: simultaneous support for native resolution on the built-in display and up to 2560 by 1600 pixels on an external display, both at millions of colors

  MacBook Air (13 inches, beginning 2014) - technical specifications

  However, the max possible resolution may be limited by the type of connection, or the specific adapter you use. For example, this Mini-DisplayPort-HDMI adapter supports up to 4 K (~ 3840 x 2160) resolution:

  Belkin 4 K Mini DisplayPort to HDMI adapter - Apple

  .. supported .While this Mini-DisplayPort-HDMI adapter only supports 1920 x 1200:

  Amazon.com: AmazonBasics Mini (Thunderbolt) adapter DisplayPort to HDMI: computers & accessories

  Then how you connect to an external monitor can certainly affect the maximum resolution available. In this case especially, however, I suspect that the issue is actually the screen itself, as it appears from the Samsung S32E590C screen to list a 1920 x 1080 max resolution:

  Support - curved screens S32E590C | Monitors Samsung

  I hope that was helpful.

  See you soon

• External monitor retina has no power for MacBook Pro

  My external monitor retina stopped providing power to my MacBook pro (OS 10.10.2) and so will not come.  I tried to reset the SMC, but it did not help.  I plugged the MacBook to external Retina to another (same model) and it works fine.  I unplugged everything, plugged the screen on a multiple power outlets different without success.  I plugged the screen on a different MacBook and encounter the same problem - no power.  The problem seems to be in the monitor, no not the computer.    Is there a reset of the monitor or something else, that I can do?

  Hello sh5345,

  Thank you for using communities of Apple Support.

  Looks like you have isolated well enough the issue of power to a problem with the display. You can take a look at this link for your technical support options to get repaired display.

• application (adobe reader software) opens in the external monitor; How can I do ap open in the primary?

  Running Win 7/64 with 2 monitors.  Program opens in the external monitor, not primary.  Have you tried a primary mobile window, exit ap, then re-opening: no solution.

  Hello

  ·          The same thing happens with other programs?

  Try this:

  a. open a PDF file. Now, UN-maximize the file. Hover over to the other monitor. Now, close the document WITHOUT maximizing it on the new monitor.

  b. now try to open a PDF file. It should open on the new monitor. Blow it up and close it again. Now, a new PDF opens on the new monitor, and it will be maximized when opened.

  c. therefore, apparently, the trick is to close when it is not expanded on any monitor you want to open on. Adobe will remember whether or not a document has been expanded and open PDF one another in the same way, but it will update the monitor to use when a document is closed so that not maximized.

  Look at this link in the Adobe forums: http://forums.adobe.com/thread/392726

• External monitor (projector HDMI) not recognized in CC AE or AE CS6 with the new Macbook Pro

  You have a very difficult problem that maybe someone can help me find a solution.  I had an old Macbook Pro (2009-ish) I was using with AE and my HDMI projector to do the work of projection mapping.  The laptop computer motherboard used recently (not linked, I don't think) but now I bought a new Macbook Pro and am trying to use the HDMI output to the projector as my external monitor in After Effects (I tried both CC and CS5.5 and CS6). Under Preview video it does not appear as an option to send to (the choices are computer monitor only or Firewire).

  I'm a mess that I'm supposed to do a show tonight with the installation I did many times with my old Macbook and AE and now can't do it at all. I have to be able to have the projector receive EI feed - and nothing I've done so far has helped. The system sees the projector, then why doesn't AE?  I can't drag the window of the program in the projector window space and expand - there must be exactly 1920 x 1080 in order for me align correctly.

  If there is Adobe TAPI people this morning, I'd CERTAINLY appreciate your comments, as well as any other person who might have had similar problems. It should work, it should be a no-brainer. Right now I'm running a new STANDARD Apple Macbook Pro with HDMI output and the latest version of AE CC with all updates done. Please, please help!

  Thanks in advance,

  Bill

  After Effects does not come with components for an HDMI output.

  Your other computer must have installed additional components that adds this functionality.

• 10.11.6 beat external monitor

  I have a MBP of 2015 the retina with a Benq 27 '' LCD monitor connected via HDMI. Everything was working just dandy and candy, until what I've updated OSX this morning and after restart - no monitor can be found. I tried SMC and NVRAM reset without success. Obviously fed the Mac and the monitor down and up several times too. Tried to "Detect displays" - nothing. Any ideas?

  Hello cameronreilly,.

  Thank you for reaching out to the Community Support from Apple. Use an external monitor everyday with my MacBook Pro, so I know how useful it can be, and I will do everything I can to help. You were on your way to a very good start with resetting the SMC and the NVRAM. Here what I would recommend is starting up from your Mac in a test user to see if the problem is specific to your user account or if it is systemic.

  To do this, you can open your system preferences and select «Users & groups» Then, click the icon of a padlock at the bottom and enter your password to unlock the options. Click the plus sign (+) to add a new user. Don't forget to make the administrator user. Once the account is set up, log on your current account and in the new test user. If the monitor is not detected in the test user, I recommend reinstall the update by using the recovery mode. This will not delete the files from your mac. This article will guide you in this process: How to reinstall OS X

• External monitor only up to 720 p using HDMI

  I recently bought a Samsung curved (S27D590C; 1080 p). My setup is a MacBook Pro 13 "(mid-2012), connected to the screen using an adapter 3-in-1 (mini DisplayPort to VGA, DVI and HDMI). When I use the VGA, I can get up to 1080 p. For some reason, I can only 720 p when you use the HDMI cable.

  The HDMI cable is probably good as I am able to get a 1080 p using a Windows laptop without adapters.

  Additional information: by using the same configuration (MacBook + 3-in-1 adapter + HDMI cable), I am able to connect to another TV which has a native resolution of about 720 p.

  Finally, connecting with the HDMI, my MacBook is able to detect the monitor but the monitor does is display a blank screen.

  I would really appreciate everyones help, because this is my first purchase of external monitor. Thank you.

  Hi Danne18,

  Looks like you can't get good resolution on a monitor, and you get just nothing to display on another using your MacBook Pro. I would use the following article to help you get that resolved. There's a lot in there and some of it is basic, but it should lead you to getting this problem:
