I have a mid-2012 13" Macbook Air with Intel HD Graphics 4000 1536 MB  My monitor died recently so I'm in the market for a new one, and I would like to know the maximum supported resolution for external displays @ 60hz refresh rate on this model?  The Apple info page here  ...states that max res is 2560x1600 but it doesn't state the refresh rate.  I don't want to go for that if only 30hz is supported.  The canonical question for Macbook display resolution answers is:   This provides a link to  which has more detailed specs info than provided by Apple.  However when I lookup my MBA on EveryMac I only find the following info:     2nd Display Support: "Dual/Mirroring*   2nd Max. Resolution:  2560x1600 (x2)   Details:   *Although Apple makes no mention of it, third-parties have discovered that this model can simultaneously support two external displays up to   2560x1600 "daisy chained" via Thunderbolt."   As with the official Apple specs, this does not give the refresh rate supported at 2560x1600.  Commenters have suggested that 2560x1600 is only supported @ 30hz... in which case my question still stands: what is the max resolution supported @ 60hz (for my specific model of Macbook)?

How do I find out the number, type, resolution &amp; refresh rate of additional monitors I can attach to my MacBook or MacBook Pro?  This is an attempt at a canonical QA, as per the Meta QA -   to try prevent the myriad "same but different" questions we get on every possible combination of computers, cable &amp; monitors There are perfectly good resources out there that Ask Different should not have to duplicate the efforts of.

This is on an Early 2011 Macbook Pro 17" with i7 2.2ghz and the Intel + Radeon HD6750:     If it is a screen error then I don't mind fixing it myself, but if the GPU is the problem, I'm worried I might have to buy a new logic board assuming I can't use the GPU.

The new MacBook line has a new turbo boost added to the processor:     2.3GHz Quad-core Intel Core i7, Turbo Boost up to 3.3GHz   What exactly does this mean? From what I've heard, the processor can runs above the clocked speed for a short period of time.  How does it work?

My Mac doesn't recognize my TV's resolution on (so far) 3 VGA cables I've tried but it works just fine using other seemingly old VGA cables. My roommate had the same experience on Mint Linux.  What's the difference between VGA cables? What should I look for in a VGA cable that I buy? Are those still being made?

I know the LG UltraFine 5K monitor has the  ability to supply enough power to charge a 15" MacBook Pro () but is there a way to tell if a different monitor supports this function?

I am running Mac OS X (Version 10.10.5) on a MacBook Pro (13 Inch, Mid 2010) and want to arrange an external monitor of the same type to different positions.  First, let me explain my setup:   monitor at my office: DELL U2312HM (located above the MacBook's screen) monitor at home: DELL U2312HM (located left of the MacBook's screen)   As you can see, I am using different monitors of the same type (they have different serial numbers displayed in the System Overview window). However, they are located either above or left of the internal screen.  Since the only way I know to arrange an external monitor is draging the blue boxes in the monitor section of the system preferences, I need to do this every morning after connecting my monitor in the office and every evening after coming home. The monitor arrangement does not depend on the monitor's serial number but on the model since saving the arrangement of different models works as desired.  So is there a way, a hidden setting, a hidden setting accessible through the terminal or even a third-party app which enables different monitor arrangements for the same monitor model but based on the monitor's serial number as shown in the system overview?  The behavior which seems to be a system default is very annoying and does not feel very apple-like.

I'm on a MacBook Pro (15-inch, 2018) with Mojave 10.14.1. When I connect MBP to a external displays (either via HDMI or via Thunderbolt 2 adapters), the temperature raises sensibly (i.e., CPU temperature lies constantly over 90°) and fans start running fast (i.e., more than 50%) frequently, even if I am doing very simple tasks (e.g., writing in Word with a couple of Chrome tabs open with stackoverflow).  I'm not sure that the problem started with Mojave or if it isn't actually related to the OS version.  I'm wondering if there is a way to limit this annoying overheating as well as fans activity, while using external monitors.

I am considering purchasing a Mac for my godson who will be using it to run Blender 2.8.  I know very little about this program.  All I can find are requirements for a Mac that will run earlier versions of Blender.  Would someone please recommend a list of requirements for a Mac (or a link to a list of requirements) that I could use to find a model that can run 2.8?  Thank you in advance for all your help! Sincerely, M. Lap

My 15 inch MacBook Pro recently has horizontal stripes on the screen. It looks like this:  It happens randomly and sometimes it gets worse (flickering with horizontal lines,stripes)  Does anyone know what might cause this and how to fix it?  No such issue during the past year...it has just started happening since yesterday.

I am, like so many other graphic designers, very excited about the new MacBook 15" with retina display. But there is one thing that I really am concerned about. With 4 times the pixels as on ordinary screen, how can we be sure, that the preview of an image, is what we really get?  When images are optimized for web usage, how can we be sure that the optimized image, is what the end user (with a non-retina display) wil be seing?

I want to connect my laptop (Inspiron 15 5000 Series) to a 4k display. When I read online about this it seems that HDMI 2.0 is a necessaity to handle the large resolutions / refresh rates involved to get full benefits of a 4k display.  Use case: I'm not going to use this to play games. Most of my use-case is editing documents, emails, spreadsheets and some engineering drawings and video (watching not editing).   The goal behind going 4k is to boost productivity by having more things open at once to read side by side.   I looked into the Dell specs and they only mention an HDMI without going into the details of what type or whether it will support HDMI 2.0 / 4K TV.     How do I tell whether my Dell Inspiron Laptop (i7 7500 U processor) supports this?  I looked under the Display Adapters and can see that I have an "Intel HD Graphics 620"  listed.   Will this suffice to tell me if this display adapter will support HDMI 2.0 / 4k display?   Or should I be checking out some other settings?  Thanks!

When I have my external monitor hooked up, I access it by mousing off the left hand side of my Macbook display. Can I switch this so that I can access the external by mousing off to the right of My Macbook display?   The reason I ask, is my monitor is on the right side of my macbook, and it's unintuitive to mouse left to get to a screen on the right.

I have a Dell S2316H monitor which I connect to my MacBook Pro (early 2015) using the built in HDMI port. The fonts are looking very blurry on the external monitor.  I own the MacBook for about a week. Previously I used my monitor with my Dell laptop which had Ubuntu installed on it. When I plug the monitor with my Ubuntu machine, the fonts are smooth and looks good. But when I plug it with the MacBook, the fonts are very blurry.  I know this is a common issue but I'm unable to find a solution. I do not have any DVI port on my monitor so I can't use the solution from . Also tried this script , but no changes. I tried with different font smoothing level too. Is there really any solution for this problem?

I noticed in this thread the OP successfully managed to connect a 30" cinema display to the new Macbook Pro USB-C, with full resolution:    I have the official Apple dual DVI adapter, going to a displayport > USB-C adapter like yours, however the screen does not fire up.  I then tried a multi adapter instead of the single displayport > USB-C, which worked but only at 1280 resolution:    Would the official Apple Dual DVI adapter not work?

I have an external monitor with a VGA connection. What is the best adapter to use for my Retina MacBook Pro? I think I've seen Thunderbolt to VGA, or USB to VGA? Or HDMI to VGA? What are the differences?

I have never really paid any attention to the refresh rate setting on computers with LCD screens.  I thought with LCD displays the pixels are either on or off, they don't flicker like in old CRT monitors.  Seems trivial to me, but my own graphics card allows me to select 59Hz or 60Hz - which leads me onto my question:  Does the refresh rate affect LCD screens?  Technical info to back up any answers would be great.

I have that problem which seemingly afflicts many using the proprietary Nvidia driver:     Video tearing: fine horizontal lines (usually near the top of my display) when there is a lot of panning or action in the video.   (Note: switching back to the default nouveau driver is not an option, as its seemingly nonexistent power-management drains my battery several times faster)  I've tried Totem, Parole, and VLC, and tearing occurs with all of them.  The best result has been to use X11 output in VLC, but there is still tearing with relatively moderate action.  Hardware:  MacBook Air 3,2 -- which has an Nvidia GeForce 320M.    There are two common fixes for tearing with Nvidia prop drivers:   Turn off compositing, since Nvidia proprietary drivers don't usually play nice with compositing window managers on Linux (Compiz is an exception I'm aware of).  But I use an extremely lightweight window manager (Awesome window manager) which is not even capable of compositing (or any cool effects).  I also have this problem in Xfce, where I have compositing disabled. Enabling sync to VBlank.  To enable this, I set the option in nvidia-settings and then autostart it as nvidia-settings -l with my other autostart programs.  This seems to work, because when I run glxgears, I get:  $ glxgears  Running synchronized to the vertical refresh.  The framerate should be approximately the same as the monitor refresh rate. 303 frames in 5.0 seconds = 60.500 FPS 300 frames in 5.0 seconds = 59.992 FPS   And when I check the refresh rate using nvidia-settings:  $ nvidia-settings -q RefreshRate Attribute 'RefreshRate' (wampum:0.0; display device: DFP-2): 60.00 Hz.   All this suggests sync to VBlank is enabled.  As I understand it, this is precisely designed to stop tearing, and a lot of people's problem is even getting something like glxgears to output the correct info.   I don't understand why it's not working for me.   xorg.conf:   Example of observed tearing::
