Mac Mini does not detect DVI display on startup

Okay, I have a Pre 2009 Mac Mini 2Ghz Core 2 Duo. My monitor is a Westinghouse Digital LCM-22w3. The display is hooked up through DVI. When I start or restart the mac, it seems that it does not detect the display is plugged in. I have to wait for OS X to finish booting to either put the mac to sleep and bring it out of sleep or unplug the DVI cable and plug it back in to get the display on. If I hook the display via VGA using the VGA to DVI converter there is no problem. I have tried resetting the NVRAM but that does not fix the problem. I would like to get this fixed so I don't have to switch cables to be able to boot my boot camp windows install. Any help is appreciated. Thanks!

Following some investigations the problem appears to be with the power saving features of the monitor.
The MAC mini knows that the monitor is connected but the monitor puts itself to sleep.
The problem appears only when you use a single link DVI-D cable.
These are the ones with two blocks of nine pins with one large blade.
If you use a Dual link DVI-D cable (twenty four pins and one blade) the problem resolves itself and the display is active from power on.
It looks like the mini or the monitor is using one of the pins from the middle block of six for some reason.
Anyway, good look with this, I had a couple of spare DVI cables from when I was trying to get my original G4 mini working with my TV.

  • Mac Mini does not detect DVI monitor on boot but does so on awake

    Hi,
    my Mac Mini fails to detect a monitor on the DVI port when it boots (monitor says no signal).
    If I leave it a few minutes to boot, then put it to sleep and awake using the power button, then the display appears.
    This problem does not occur with the DVI-to-VGA adapter, and I have tried with 2 separate DVI monitors (different brands) and cables (both monitors are fine with Windows PCs).
    I have tried various resolutions and color depths, to no avail.
    Any ideas about how to resolve this?

    What brand and model of monitor do you have?

    Hello,
    I have bought new mac mini (late 2012) with OSX 10.9.4 installed on it.
    I have apple cinema display (20"), model: A1038 from before. When i turned on mac mini the display was not detected.
    I also have one Samsung monitor which was detected without problems.
    I tried next steps already:
    - connect only apple cinema display with HDMI to DVI and turn on coomputer
    - connect only apple cinema display with mini displayport to DVI and turn on coomputer
    - connect both displays, went to System preferences -> display and click on 2Detect display"
    nothing works
    Specs of my mac mini:
    mac mini (late 2012)

  • Thinkpad Edge S430 - Windows does not detect external display connected via HDMI

    On a Thinkpad S430 with HD4000 integrated graphics, an external display connected via a HDMI cable is not detected at all when using Windows. The system is fully updated as of the time of posting this message, both via the Lenovo Update tool as well as Windows update.
    The Intel driver version is 8.15.10.2696. It appears that this is the latest version, since it does not offer an update when I try to auto-update it via Device Manager.
    NB: I am running Ubuntu 12.04 with kernel 3.4.0 on the same machine, and the external display works perfectly fine with this software configuration.
    Hence I think that it's very likely that this is a Windows-specific driver issue.
    Would Lenovo happen to have a driver update in the works? Alternatively, I will be thankful for any suggestions about possible resolution of this problem.

  • ITunes on new Mac Mini does not show shared libraries on network or songs on NAS drive

    iTunes on new Mac Mini does not show shared libraries on network or songs on NAS drive
    The latest version of iTunes on a 3-month old Mac Mini (8 gig RAM, OS 10.10.2) does not see any of the shared iTunes libraries on a  MacBookPro (MBP) (OS 10.9.5) and a 14-month old Mac Mini (OS 10.9.5). And a network shared drive/media server does not appear as well. I have a Gigabite Ethernet G4 and on it, the MPB and the "old" mini I can see the various shared music libraries and NAS, but not on the new Mini.
    The little house with a music note inside it that I see on the upper left corner of the iTunes 12.1 window on my MBP does not appear on iTunes 12.1 on the new Mac Mini. I have gone through all the iTunes preferences and can not find where I can turn on this feature. The new Mac Mini is on the local network and I can reach the internet successfully.
    I have been using iTunes since its beginning (still have a PowerTower Pro with a working copy of SoundJam), so I am not a newbie, but this has me baffled.

    May I add, that I gave full rights to the user at the Mac Mini to access and change data on the server drive for ITunes Media.

  • My mac mini does not boot, after backing the enire system onto an external drive with Carbon Copy Clone

    My Mac Mini does not boot, after backing the enire system onto an external drive with Carbon Copy Clone. I had switched the start-up disk back to the original of course. Now all I see is the Apple logo. What should I do? Thanks in advance.

    Try disconnecting any external devices, especially hard drives
    and try rebooting.
    If that doesn't help, then :
    If you are running Lion, boot to the Recovery HD and run a
    Repair Disk on the OSX partition.
    If Snow Leopard, boot to the installl DVD and run Repair Disk.

  • Help - Mac Mini does not boot after re-install of OS X

    Hi,
    I have a Mac Book Pro and Mac Mini. I needed to reinstall my Mac Mini but lost the install disks. The install disks of the Macbook do not work (machine specific). So what I did was boot the Mac Mini in firewire target mode and installed OS X to it from the Macbook. Worked ok. Except for one thing: The Mac mini does not boot the fresh OS X installation. I get a blinking folder icon with a question mark on top of it.
    I booted from the Mac OS X install disk, repaired disk permissions etc. and tried to use the "Startup Disk" utility to select the hard drive as a boot device. But that utility does not offer me to select the hard disk, it doesn't even show up (while DiskUtility can perfectly see it).
    Any hints for me? I am pretty much stuck right now.
    Thanks

    Well, see, the fact that it wouldn't let you boot from the MacBook install disks should have been your first clue to not try to do it. There's a reason it wouldn't let you. The MacBook install disks contain a version of the OS specific to the MacBook, in order to prevent people doing what you just tried to do (ie, installing the same copy of the OS on multiple machines).
    If you don't have the Mac Mini system disks any more, you'll have to go buy a copy of OS X. You could also ask for help from an Apple Store, if there's one in your area, but I honestly don't know if they would give you new disks. I would think they should (for a small fee), since Mac Mini system disks would be useless to anyone who didn't already own a Mac Mini, but you never know.

  • My new mac mini does not see usb drives, but in hardware info the usb is visible

    my new mac mini does not see usb drives, but in hardware info the usb is visible
    i'tried several usb flash drives even brand new ones, they are visible onder hardware info but they are not on the desktop nor in the finder.
    what is wrong and doe anyone has a solution ?

    It does not show up in disk utility, its only visible through systeminformation.
    When you plug in the USB flash drive and then refresh systeminformation it becomes visible.
    To remove it I shut down the computer because I cannot eject the USB device anywhere.
    After starting up again when I have removed the flash drive it has gone from the systeminfo USB list.
    By the way my USB mouse and keyboard are working fine, I also changed ports of these and they still keep on working so I don't think the USB ports are defect.
    I guess it some kind software problem, and because I'm new to Apple I do not know much about it how to solve this.

  • Mac mini does not boot, no video signal, no chime

    My mini "starts" without chime when I press the power button on the back. The fan starts, the light in front goes on and I hear some clicks which could be the hard drive. The screen remains black (no signal) and the mini does not respond to the USB keyboard power button. It does not start when pressing it and will not power down if I press it for any length of time when it is on. Pressing the power button on the back for some time shuts it down.
    Time to get a new one?

    You can try:
    Resetting your Mac's PRAM and NVRAM
    Intel-based Macs: Resetting the System Management Controller (SMC)
    Then try booting from your installer DVD. If still no success then you most likely have a hardware failure.

  • Mac mini does not recognize external drive

    I have an 80GB external drive full of music files. I disconnected my computer to move to a new house and, with everything re-connected, the mini does not recognize the external drive. I wonder whether it is because the internal drive is nearly full. I have tried restarting the computer, disconnecting and re-connecting the USB cable to the external drive, serching for it with the disk utility, un-pluggin the external drive power cable and re-connecting it, but I'm out of ideas. What might have happened?

  • MAC Mini does not restart after Yosemite update

    I bought my MAC mini in 2011 and I successfully updated to Mavericks with no problems.  I am not sure why my MAC Mini will not restart after I updated to Yosemite. The completion bar gets stuck around 30%.
    Any help or ideas appreciated 
    Larry

    Okay, this is strange.  I tried restarting three times yesterday with the same results. In fact I left it go overnight only to find the next morning that the bar was still stuck at 30%.  I did a hard boot a little bit ago and waited a few seconds. I restarted an it booted up fine.

  • Mac Mini does not display HDMI 1080i in full screen on TVs

    I have a 1.66 GHz Intel Core Duo Mac Mini that I am having problems getting video to display 1920 x 1080 @60hz in full screen on my Sony XBR 1080p HDTV. The Mac is connected to the TV via a DVI to HDMI cable. The Mac recognizes the display as a "Sony TV"
    When the Mac first starts up the entire TV screen is filled with the grey Apple startup screen, but when the Mac fully boots and gets to the desktop, the screen has shrunk so that it is slightly off the screen on the left, and has about 80% of the screen filled horizontally and about 90% vertically. I have tried all combinations of the overscan selection on the Mac and on the TV, but they make the image about 120% of the size of the screen so the top, bottom and sides are cut off.
    I have tried 2 different 1080p HDTVs with the Mac Mini and get the same results for both TVs.
    Now here is the thing that makes me believe that there is something funky with the Mac Mini. If I take my 2.16 GHz Macbook Pro 15" Intel Core 2 Duo and plug its DVI display port into the Same DVI to HDMI cable that is connected to the same Sony TV, it displays full screen with no problems.
    What can I do to make my Mac Mini display properly?

    Thanks for the ideas.
    I did as you suggested, but the only 1920x1080 selection shown was one for "NTSC" which I would think is interlaced. This was after a reboot. All of available resolutions are labeled with "NTSC". When I look at the screen resolutions on my MacBook Pro when it is connected to the TV, they are labeled as "Interlaced". On both computers there are no progressive scan selections.
    As an interesting note, regardless of what display resolution I select, the display area on the TV screen remains the same which is about 80% of the screen offset to the left. When "overscan" is selected, this mode enlarges to image to about 120% of the screen and cuts off the menu bar etc. However the MacBook fills about 98% of the screen in "normal" mode.
    If there was a less aggressive Overscan mode or more aggressive normal mode, that would fix the issue.
    Any other ideas on how to adjust this?
