2014 mac mini dual monitor problem

I just brought a mac mini (Late 2014) i have two displays monitors connected, one HDMI to DVI. and one thunderbolt to DVI. I can have both thunderbolts connected and the problem its the same, when back from sleep ,one monitor doesn't turn on. i have to disconnect one and then both work, it only happens when the mac goes to sleep. on cold restart or turning the mac on, this problem doesn't occur. any help.

I have this same problem too. I purchased the Mac Mini with the intention of running dual monitors. I'm using the HDMI and mini-display/Thunderbolt to DVI. I've also tried MiniDisplay/Thunderbolt to HDMI and I'm experiencing the same problem as angelfromfullerton. Whenever it tries to wake from sleep, it can't decide on monitor arrangement and keeps flicking between the two, making the OS unusable and forcing a reboot... EVERY TIME. I've also experienced the issue once or twice on a cold boot. It doesn't matter which Thunderbolt port is used either.
I'm going to have to return my Mac Mini unless this problem is fixed asap.
Mac Min, OSX Yosemite (10.10).

  • Mac Mini DVI Monitor Problems

    Hi all,
    I'm running OSX10.8.5 on a Mac Mini 2.5 GHz Intel Core i5 with 4 GB 1600 MHz DDR3 memory and Intel HD 4000 512MB graphics.
    I've just upgraded my monitor from a VGA 17" to an AOC E2462VWH 24" monitor, plugged into my computer via DVI with a Thunderbolt adaptor.
    In a normal boot-up, the monitor displays video for a split second and then cuts to black. The picture works fine in Safe Boot mode but video is jerky, everything loads slower, I can't play .mov files (Quicktime tells me unknown error -101) and there is an annoying flicker every 10 seconds. The fact the monitor works fine in Safe Boot suggests to me the problem is software. Resolution is set to 1920 x 1080 @ 60Hz and OSX is not letting me change that via Settings.
    I went searching for drivers only to lean it sounds like OSX deals with monitors in a plug-n-play format. Is this true?
    Firstly, can I confirm my mini has the power to drive this monitor?
    Besides that, can you please help me figure out how to boot this computer so the monitor displays in normal boot-up mode?
    Thanks for your help!

    Then it sounds like yo need one of these:

  • Mac Mini 2011 - Monitor Problems - Help

    My picture is not sharp... just blury. Icons, pictures, text, mostly everything is bad except high quality video files.
    I just purchased a Mac Mini 2011 second option and a Samsung TA531 monitor that arrived today. Hooked it up and to my surprise, it is blury and bad quality no matter what kind of resolution i use. I also try to text smoothening through terminal.. nothing helps.
    My setup:
    Mac Mini 2011 - second option stock
    Samsung SyncMaster T27A531
    Cable: HDMI
    After reading about this issue, some people recommends to use a DVI or VGA cable and claims that HDMI is not suitable for computer monitors, especially Samsung.
    Please, feel really sad and lost among a lot of new computer equipment that doesn't work properly

    I had the same issue and didn't want to give up my Thunderbolt port, so I opted to get a Gefen HDMI Detective Plus. What this does is make the CPU think an HDMI display is attached so that your graphics CPU 'unlocks' and full speed is back. The Gefen box can either 'learn' the code of any HDMI display in your office/home, or you can preset it as a stock 1080p display. TOTALLY solved my problem... even though it did cost $85.
    Apple needs to fix this as so many people use the MINI headless.

  • Mac Mini dual monitors?

    Hi Guys!
    Can a brand new Mac Mini (latest edition) support 2 monitors, and if so how (what should i buy)?
    ** I have 2 brand new monitors with DVI cables.
    Cheers!
    I.

    Marina,
    I do not know the exact pixel resolution of my monitors, but I did connect my mac mini to two 24" monitors of different make and I still like the result. The "HDMI to DVI" adapter was supplied with the mini (server with 8GB RAM but I use it as a normal mac only, not as a files server). I bought the "Thunderbolt to DVI" adapter separately and I needed two DVI cables (one I found in the office, the other I had to buy). That was it. I tried to connect the second monitor directly using a HDMI cable but that had a downside. That monitor was not switched on and off by the mac via the HDMI cable. The HDMI cable is more suitable for TV connections. With the DVI cable that problem was solved.
    I hope that this helps.
    All the best and merry Christmas

  • Mac mini dual monitors setup

    Hi, i just got my mac mini and have placed the order for 2 Dell U2312HM monitors. I want to get the correct cables for the dual monitors setup before the delivery. Could any one comment if i got it right? Thanks. -Jason
    - Mini DisplayPort to DVI adaptor x 1
    - HDMI to DVI-D Cable x 1

    You have it right.
    Your monitor has:
    Full HD resolution, 1920 x 1080 at 60 Hz
    The 2012 mini supportds:
    supports 1920x1200 on an HDMI or a DVI display (using the included HDMI-to-DVI adapter) and2560x1600 on a Thunderbolt or Mini DisplayPort display or even a VGA display (with an optional Mini DisplayPort-to-VGA adapter, which is compatible with the Thunderbolt port).

  • Mac Mini VGA monitor problem: monitor powers off after 15s

    Hi
    Trying to hook up a Mac Mini to an ancient VGA monitor (Logix). Bought a Mini Display Port to VGA Adapter. On power up the apple logo displays on the monitor, but then the monitor screen goes black and the power light on the monitor flashes.
    Is this the Pin 9 problem referred to here?
    http://en.wikipedia.org/wiki/VGA_connector
    The monitor only has a VGA input. If the solution is to go buy a new monitor that is fine, but seek advice on which type (budget is an issue)
    thanks

    Update: I have determined that this is due to a bad connector on the internal fan. One of the wires in the connector popped out, and when I put it back in, the first time it went in backwards, so when I tried to attach the fan cable, it crimped the end of the wire connector. That means that it doesn't securely fasten to the internal board. I can situate it to the point where it touches for awhile, and during this time, the Mac Mini does boot up with a solid power light, and stays on. However, eventually the wire goes loose, shutting down the fan, which in turn shuts down the Mac Mini.
    Things I've tried:
    - I've searched for a fan replacement on the web, but it cannot be found for purchase (not even on eBay).
    - I went to Frys Electronics, but they don't have the fan nor that connector.
    - I went to the genius bar at the local Apple store, and was informed that Apple nor Apple Authorized businesses are "allowed" to sell me the part. They did confirm that the fan not properly connected would cause the symptoms I'm experiencing.
    I guess at this point, I need to do one of the following:
    1. Find an unauthorized Apple repair business would be willing to sell me this part.
    2. Figure out how to fix the connector on the wire so that it securely attaches to the prong.
    3. Pay Apple over $100 to fix what is basically a $5 repair (this option is largely undesireable).
    4. Find someone who is throwing out a broken Mac Mini where I can scavenge for the fan.
    Any other suggestions, or any help in accomplishing my goal would still be greatly appreciated.

  • Advice: Mac Mini / Dual Monitors / PC Mac Configuration

    Hey Guys, need some advice for a semi-switcher friend.
    I have a business associate who has asked me the following questions and wanted some advice from the mac forum.
    My friend's background is as professional web site developer. He is currently using Windows XP with dual monitors.
    His boss is going to buy him a Mac Mini to work along side his PC. He wants to know what would work for dual monitor / PC / Mac Mini configuration.
    Here are his questions:
    "One, what do I need to do to run dual monitors on a Mac Mini since it doesn’t have another graphics card like my PC?"
    "And two, what is the best way to use my dual monitors with my Mac and PC? Should I trash the PC and use Bootcamp/Parallels or use something like a KVM switch since the Mac doesn’t come with a keyboard or mouse?"
    "I still need to be able to do testing with IE7 and Firefox (which I believe is different on a Mac than a PC), so that’s why I considered using Bootcamp or Parallels. (I prefer Parallels due to the rebooting of Bootcamp, but am wondering if I might experience any troubles otherwise and am better off with Bootcamp since it’s a Mac product and not third-party software. I’m neutral on this.)"
    Any help or suggestions would be welcomed.
    Thank you in advance.
    Mac Mini   Mac OS X (10.4.3)  

    There is one factor you might want to pass on to your semi-switcher friend in his consideration of a mac system.
    There's a subtle difference between MacOS and Windows that can significantly impact on how well a Windows user adjusts to the Mac, particularly when used to dual head operation. Windows attaches a menu to each and every window (and application) whereas MacOS does not. While a Windows user only has to navigate to the menu bar at the top of each window, a MacOS user has to navigate to the single menu bar along the top of the screen (or primary screen if on a dual head system.
    It's not a major issue, but for a pro used to simple and quick navigation off on the secondary display, having to navigate over to the top of the primary display to do something instead of quick flick up and done, there can be a small degree of frustration and a slight impact on workflow.
    I hasten to add that with those I have seen make this very transition, the effects were short lived, but it leads to the thought that where the Mac is concerned, it might be marginally better to go for a single widescreen display than dual head.

  • Mac Pro Dual Monitor Problem

    I have a MacPro 4,1 with an ATI Radeon HD 5770 video card. I'm running OS X 10.6.8.  I have an Apple 20" Monitor and a Hannspree 23" monitor.  The problem I have is that when the computer goes into standby mode, 2 times out of 5 it will come back up with the primary monitor switched from the Apple to the Hannspree.  I then have to go into the Display Preferences and switch the monitor arrangement, and the menu bar.  Not a huge problem I grant you, but one that is vexing me nonetheless.
    Also on an occasion...perhaps 1 time out of 25 the Apple monitor has a case of the jaggies, and is only fixable by shutting down the whole computer and restarting.  This is really bad, considering it reminds me of when I get migrane headaches and my vision is constricted.  It almost makes me nautious.

  • 2014 Mac Mini connected to Samsung s22b310b monitor colors bad upon waking from sleep.

    Occasionally when I wake the 2014 Mac mini from sleep the colors on the monitor are very bright.  I go into systems preferences and then display.  I click on the color button and it will change back to normal.  I have tried both a DVI to mini displayport and VGA to mini displayport.  Problem occurs with both.  What else can I try to prevent this from happening?

  • Can I use a VGA/DVI-D monitor to a new 2014 Mac Mini?

    My wife's PC just died (it was a cheap 300 pc that lasted probably 5 years.
    She basically emails, web surfs, looks at pictures and plays candy crush on Facebook so she doesn't need anything too high end.
    I was thinking of getting her the basic 2014 mac mini but I have a VGA/DVI-D monitor (an older Dell) and it fits perfectly on her desk.
    Can I somehow hook up a new mac mini to either the DVI-D or VGA input?
    If not, what is the best monitor to get HDMI or should I look into a thunderbolt monitor?
    Thanks,

    Yes. You will have to purchase one of the following adopter:
    - HDMI to DVI and use the Minis HDMI output
    - Mini displayport to DVI adopter and use one of the Minis Thunderbolt ports
    - Mini displayport to VGA adopter and use one of the Minis Thunderbolt ports
    I would use the monitor's DVI input over the VGA input

  • Dual boot OS X 10.10 plus OS X 10.6.8 on new 2014 Mac Mini?

    Hi,
    I am currently thinking about buying a 2014 Mac Mini. As I still need to use some very expensive (albeit old) software, I would like to run a copy of OS X 10.6.8 (strapped for cash).
    I currently own a 2011 MacBook Pro 17" and I have partitioned the disk and run OS X 10.9.5 on 700GB and OS X 10.6.8 on 50GB. This has worked great for the past 2 years. I simply press ‘alt’ on booting and select my OS depending on which software I need to run.
    My question is, can I do the same with a new 2014 Mac Mini using one of my Time Machine back-ups (install from Time Machine option on istall)?
    I would be very grateful to anyone who can offer me some advice.
    Many thanks,

    Other than running Mac OS X 10.6.8 Server in a virtual machine as previously suggested your next best option is to consider buying a secondhand older Mac that is capable of running 10.6.8.
    Just to make it clearer, 'ordinary' 10.6.8 is not allowed due to Apple's license terms to be run in a virtual machine only the 'server' version is. The server version of 10.6.8 can run normal applications and you do not have to use the server bits itself. If you try installing the 'ordinary' 10.6.8 in to a virtual machine it will not work as they check for this.
    The new 2014 Mac mini will not run 10.9.5 either, the 'oldest' version the 2014 model will run is 10.10, it will of course also run 10.10.1.
    1)     Older Macs are just that: older and out of warranty.  So of course the user is subject to the risk of hardware failure without necessarily much warning and little or no recourse (other than purchasing another older Mac) when the hardware does fail.  This may also be a different problem for the OP, as cost appears to be a major consideration here.
    2)     The use of Snow Leopard Server in Parallels will cost about $99 retail (less, if some shopping for "discounts" on Parallels is done on the internet).
    Installing Snow Leopard Server into Parallels for DUMMIES:
    http://forums.macrumors.com/showpost.php?p=17285039&postcount=564
    3)     It was a common myth that the Snow Leopard EULA prohibited its virtualization in Lion and thereafter on a Mac.  That myth has been debunked in the 3-1/2 years since Lion was first released and repeating it now does not make anything "clearer" but only tends to confuse an OP.
    In any event whatever remains of that long forgotten debate is now mostly moot since Apple reduced the sales price of Snow Leopard Server by 95% (by telephone orders only; 1.800.MYAPPLE (1.800.692.7753) - Apple Part Number: MC588Z/A); that is, for the same $20 as it sells Snow Leopard client and it is much easier to install, use and maintain Snow Leopard Server in virtualization, including Parallels.

  • 2014 Mac mini doesn't scale the entire HP Envy 32 monitor screen

    I recently purchased a HP Envy 32 monitor for use with my 2014 Mac mini with the Iris display. I get 2560x1440 resolution at 60 Hz on both the DP (1.2) as well as the HDMI ports (using the auto-detected HP Envy 32 color profile) but the display doesn't scale the entire screen of the monitor. Is anyone else using this configuration successfully? If so, what have you done to make full use of the 32" monitor real-estate? I simply cannot find any options in Display preferences (Yosemite) to change underscan options or for that matter within the monitor itself. Is there a particular display profile or driver I can use to fix this issue?

    I'm using a 4K compatible DP cable connected to the Thunderbolt port and getting to the max resolution of the monitor. So I don't think the issue lies there. I was able to use SwitchResX trial mode to discover an underscan option that allowed me to scale to the entire monitor screen. Assuming SwitchResX is manipulating core OSX functions, I'd assume there is some display related configuration within OSX that I should be able to tweak in order to scale the monitor screen natively in OSX without requiring any 3rd party software. Any thoughts for how to go about tweaking the display natively?
    Thanks

  • 2014 Mac mini 2.5" SSD upgrade

    Hi all.
    A long time Mac Mini fan here - after spent almost 3K for Mac Pro (outdated in few years) that I have to "accept" Apple's product refreshing strategies - that upgrade my hardware periodically is the trend.
    Since then, I have turned to Mac Mini - for the small fraction of cost, I can "update" my Mini more frequently.
    2009 Mac Mini x 2 (mine and my spouse's) are currently at grand children's possession, still going strong.
    Now, we have 2010 (TV at bedroom), 2011 (mine) and 2012 Mac Minis.  They were all the top Spec models - at the time.  2012 i7 Quad core, 2011 i7 with 6630M AMD video etc.
    Cut into the story - I also put SSDs in all of them ( 1T SSD in 2012, 256Gb x 2 dual drives in 2011 and 256Gb in 2010) plus used Terminal to enable "TRIM" - until 10.10. .. sigh
    Along with iOS 8.1.1 - I start to notice the inadequacy of my 2011 Mac Mini - airdrop/hand off will not work natively without some modification.
    After tossing around getting an 2012 i7 Quad-core Mini ( 800-1000 USD) or - jumping into the fixed memory, 2014 Mini?
    I decided to order a base model of 2.6GHz i5, with stock 1T hard drive, 8G ram (639-699 USD).  Because I have few 512Gb SSD sitting around - I was torn to order the higher end model with PCI-e Apple OEM SSD 512G.  After all the price adding, I realize I can buy TWO base 2.6GHz i5 Mini than 1 customized high end Mini.
    Through the web, I found the Fusion drive model (2014, oh, with USD 200 extra) has PCI-e 128Gb SSD and 1T HDD.  I am hoping one day, iFixit will have the part for the PCI-e cable/setting to be placed in 2014 Mini - for some people want to play around.  For now, I am settling with slower speed of SATA-3, third party SSD without TRIM.
    According to UPS, the my new toy will be delivered Monday and I will post more details about this SATA SSD upgrade process.

    After few days of testing.
    I finally solved the problem of screen flickering ( when an app is opened, or few apps are opened), the screen will flicker on the app(s).  This happened on Firefox, MS Word, Soundtrack (yes, I am still using it). iTunes, iPhoto, even "system preferences" etc etc.
    First, my system was built via Time Machine restore - after SSD (Crucial 512Gb) on the SATA-3 port. ( theoretically would be slower compared to PCI-e SSD) on my 2014 Mac Mini 2.6Ghz, 8Gb memory. ( I chose the basic 2.6Ghz base model to save few $$, since I have two 512 Gb SSD laying around, instead of custom-build for 512 GB SSD PIC-e, with USD 1,299.00 price tag).
    I tried numerous methods to avoid the flickering ie - PRAM reset, HDMI -> monitor, HDMI -> DVI cable, Thunderbolt -> DVI, Thunderbolt -> VGA on two different models of screen : no success.
    The only time I could get a normal decent "flicker free" was when I booted into safe mode - after reboot - same issue.
    I also used hardware check as Mini indicated "no issues" on the hardware.
    I went to Apple Store and play with their set up - no issues (of course, Mac Mini was hooked on the Apple Display, wow!)
    I started to wonder - either it would be OS X issues or "third party" software??
    So, I took the 512 Gb SSD out (it is some sort of "pain" to open 2014 Mini), then used another SSD (120 Gb) for a clean install.
    A fresh 10.10.1 on 2014 Mac Mini without other 3rd party software - worked great, no flickering at all.
    I started to add the apps I normally have, one by one to test - UNTIL -- Microsoft Office 2011 (home and business version)
    I have Outlook to synch with my Calendar, and typical Word, Excel, Powerpoint on my system.
    As soon as I put Office 2011 on it - Voila!  I found the culprit.  It was running 14.4.6 version.
    So, I put my 512Gb Crucial SSD back (another pain again) and booted up normally - same issues.
    I have been check Apple to see if OS X 10.10.2 becomes general public release (hoping the problem would be accidentally fixed) - in the mean time, I was using my 2011 Mac Mini as the main system.  2014 Mac mini was on the disable list.
    Until today, Office 2011 released 14.4.7 - I gave it a try and finally, Mac Mini 2014 with Iris GPU would not demonstrate "flickering" issues after the update!
    Whew!!

  • Is new 2014 mac mini good for audio production

    I want to learn how to use logic pro/audio production software. Is the 2014 mac mini powerful enough to run logic pro/audio production software efficiently? any feedback would be greatly appreciated. Thank you.

    +1...
    My 'problem' with the current range is that the memory is no longer upgradable.... (What you buy initially is what you get) and i7 Quad Cores are no longer available for the MMs.. just Dual Cores....
    This is why earlier MM models via the Apple Refurb store, have been is such short supply because they sell out within an hour or so of becoming available!
    You might find this site useful for tracking down Refurbs....
    https://www.refurb.me/us/
    Note: Apple refurbs are excellent value for money as they come with the same warranties as new models... plus you can purchase the extended Applecare as you can for new models... but typically sell for 15-45% less. I haven't bought a non-refurbed Mac in several years now... and couldn't be happier with the quality and reliability of the refurbished ones.
    Example: In 2012 I bought a 27" 2011 iMac 3.4Ghz 16GB AMD 2GB 1TB plus 3 years of Applecare for 40% less than the then current new cost.... Great deal indeed!

  • What cable do i need to use to connect my grandson's old style external isight webcam to his 2014 Mac mini in order for him to be able to FaceTime me

    what cable do i need to use to connect my grandson's old style external isight webcam to his 2014 Mac mini in order for him to be able to FaceTime me

    You need either a FireWire 800 to FW 400 cable or a FR 800 (male)/FW(female) adopter.
    However. it the Mini (note that you still have the late 2012 Mini, Apple has not updated the Mini since then) has Mavericks it may not work satisfactorily. I tried it on my 2102 and I get abount 1 frame every 20 seconds. Another uses posted same problem.
    However, it it work fine on my late 2009 Mini with Mavericks
