Mac mini screen resolution not synced with monitor

Hello! I have a Mac mini at home, equipped to an hp w2408h monitor via HDMI cable. Recently, I went to my friends' house with my Mac, plugging it in to their projector and playing Minecraft. However, I had to adjust the screen resolution, and once I got back and set everything up again, the monitor said I need to 'adjust screen resolution'. Is there any way to reset/sync/calibrate the resolution to the monitor, or do I have to go back and readjust the settings? Thanks! :3

  • Changed screen resolution, not syncing with itunes

    Yesterday I charged up my ipod on a different computer than normal. While charging I was looking at some pics and all was well. However, on reaching home, I discovered that the ipod has zzomed everything and hence I am not seeing all the apps at the same time - only about 3 at a time. This has also led to great difficulty in moving the apps around to open them up. It is still playing music and I have not lost any onfo, it is just very difficult and time-consuming to do it. When I hooked it up to my computer at home it is not being read as being there and hence it is not syncing either. I need help please!!

    This is the zoom feature. You can learn about it in the manual ( including how to turn it off):

  • Mac mini late 2012 not working with small VGA monitor

    I got a mac mini (late 2012 10.8.4 all updates installed) and it is working fine with samsung b2230 via VGA adapter. There is a small VGA monitor (PL8006 max at 1024*768) which works fine when connected  to a PC.
    When I connect the small VGA monitor to mac mini it is not displaying anything (monitor shows blue screen with letters VGA so I assue it is not getting any signal). Mac's resolution is set to 1024*768 with 60Hz (even tried with 800*600 without any success). Monitor is also not working with win 7 installed in mac mini using bootcamp.
    Any thoughts?

    i just found that when the VGA cable of the small monitor is slightly inserted into the VGA adaptor it works fine (this is not usable because there is no way to keep the pins at that level) and when the pins inserted fully / moved little it is not working. Since this happens only between these two devices can't find which one is faulty.

  • I used to sync my ipad on an asus laptop, now I have a Mac mini and want to sync with it. Can I? Can things be transferred from laptop to Mac mini?

    I synced my ipad2 with an asus laptop. Now I have a Mac mini that I want to use for syncing and backup. But when I connected my ipad to the Mac mini it said something about the ipad being already synced to another computer and backup is permitted only one computer at a time. How can I transfer my backup to the Mac mini ? And delete my previous (I.e. asus laptop) iTunes backup system?

    You don't have to delete anything from the Asus. You can copy your iTunes library from the laptop to the Mac. Read this for more information.

  • Bought a book on my mac in iTunes will not sync with iPad

    I bought a book on my mac in itunes it does not show up on my ipad

    Even if you bought it on your Mac in iTunes, you should be able to open it in your iPad.  Try rebooting your iPad.  Press and hold BOTH the power and home buttons at the SAME time for at least 10 seconds (ignore the red slider to shut down) until the Apple Logo appears and your iPad will restart.  See if the book shows up in your library.
    Also, when in iBooks, open the Store and click on purchased on the lower left hand side of the page.  All the books you've purchase should be in the list.  If the book you purchased isn't downloaded, click on download and it should download.

  • My Mac Mini will charge - but not sync with - USB-connected devices (ipod, camera, memory card reader). How do I fix it?

    My Mac Mini will charge - but not sync with - USB-connected devices (ipod, camera, memory card reader). I have tried unplugging the devices, restarting the computer, selectively unplugging and plugging in the devices, closing and opening the relevant applications (iTunes, iPhoto, etc). I have tried using different USB cables.
    It's like all of a sudden the synching service stopped functioning or recognizing these devices for some reason. The other ports work just fine (monitor).
    The only USB-connected external device that appears to be unaffected is the USB SuperDrive and it works on all the USB ports into which I plug it.
    How do I fix this?

    Open Console in Applications>Utilities & see if there are any clues or repeating messages when this happens or doesn't happen.

    Hello, flippytippi.  
    Thank you for visiting Apple Support Communities.
    I would need a little more information regarding what exactly you are experiencing when attempting to sync photos to better assist you.  However, here is a troubleshooting article that I would recommend going through.

  • Dual Monitors on Mac Mini Late 2014 not working on Dell S2340Lc

    Hey guys,
    Got a mac mini and using it mainly for work. Working for an ISP and no one has used macs and I've opted to be the poor sucker that gets to deal with old people that don't know how to mac very goodly.
    I have two Dell S2340Lc monitors. I have one connected up via HDMI and that works perfectly fine. I turned off the mac, I plugged in Monitor 2 with a MiniDP/Thunderbolt to HDMI adapter, powered on the mac and whilst it was booting, it had the Apple logo and the loading bar on the Dell display plugged in to the thunderbolt to hdmi adapter and then once it loaded up the log in screen, it went to the HDMI display. I logged in and in the displays section, the monitor plugged in to the thunderbolt to hdmi adapter isn't being detected, however I can plug it in to a Samsung 55 Inch Smart TV and it works just fine. I can set up dual monitors between the TV and the monitor in HDMI, but the Dell S2340Lc will only work with a HDMI cable into the HDMI port on the mac mini and will not work through the thunderbolt to hdmi adapter. On the display it just says that there is no signal coming from the computer.
    Just wondering if any of you apple gurus had any ideas as to why this isn't working?
    Thanks!

    What if you switch monitors?
    What happens if yo only have the Thunderbolt>HDMI>Dell monitor connected?

  • Is it possible the current Mac Mini 2.7 Ghz i7 with two full-resolution displays and Thunderbolt operate?

    On Second thoughts...
    I don't really know how well Logic Express 7 performs on the Mac Mini because I have not yet had the chance to experience the two together. Don't let that put you off the idea though! From my understanding of the system requirements printed on the Logic Express homepage, it states that a G4 or faster system is required, however Apple personally recommend a Dual G4 or G5 is recommended alongside a minimum of 512MB of Ram. This Does mean that Logic Express will run on the Mac Mini but you will most probably find it lags when moving samples in real time and rendering them onto your hard drive. If you really want to enjoy making "serious" music on the Mac then you really need to be looking at the iMac G5 or the iMac Core Duo (Intel) purely for your tempers sake. As for an Intel Mac Mini, there is no indication as to when we will be seeing one on the market and therefore you may find yourself on the fence between keeping your fixed budget and holding on a little or jumping in and getting on the right road to a digital musical life - mac style.
    Maybe this will inspire your decision:

  • My iPod Nano will not sync with my brand new Mac Air...will charge

    My iPod nano (touch) will not sync with my iTunes on my brand new Macbook Air. It will charge my iPod and give the option to eject the iPod, but it will not recognize my iPod to sync. Any ideas why and how to fix it?

    Hey all, I had to call Apple Support to resolve the issue as nothing on the web provided an answer. So for all you out there having the same problem, here's the ituation and full resolution, so you can save time and money (if your product's warranty is expired).
    Situation: I bought a brand new Mac Air on 12/7/12 and tried to sync my 6th generation iPod nano (previously configured to a PC) with no sucess. ITunes was only allowing me to charge and eject the nano.
    Solution:
    1. Go to View>sidebar
    2. In the sidebar, click "iPod" under the Devicies category
    3. Click "Music" section next to "Summary" under the status bar
    4. Make sure "Sync" box is checked with your preferred preferences underneath
    5. Click "Sync" in bottom right corner of window
    Apparently, iTunes 11 is quite different and the sidebar with usual options and playlists does not appear unless selected in the "View" drop-down.
    FINISHED!
