HT2998 connecting MacMini to display with after market thunderbolt-to -HDMI, not working

just purchased the mac mini, purchased after market thunderbolt to HDMI cable. connected from mini to display monitor. nothing comes up, display reads no VGA signal.

Does the monitor have a way to change input source?
I had this same issue when I first tried with my MBP, I had to do an SMC reset to get it to work.

  • Can I connect a 24" Cinema Display with mini DisplayPort in to HDMI out?

    I have a 24" LED Cinema Display that I want to use with a new 15" Retina MacBook Pro I will soon be purchasing. Using cable adaptors, would it be possible use the new Macbook Pro's HDMI port to connect to this Cinema Display? I understand that this does not work with the newer Thunderbolt displays because Thunderbolt only adapts in one direction, but since this is an older Mini Displayport monitor would it work? My goal is to keep both Thunderbolt ports available for storage I/O untill Apple releases an update to the Thunderbolt display later this or next year. Thanks for your advice!

    Yes, in this scenario, I'd connect the display to one of the Thunderbolt ports and use a USB hub for additional I/O. Here's my current I/O needs:
    1) esata (with port multiplication)
    2) gigabit ethernet
    3) firewire 800
    4) USB keyboard
    5) 3-port USB hub (iOS, bluetooth charger, misc USB2 or 3)
    6) monitor
    My current plan is to use
    1) thunderbolt 1 - display
    2) thunderbolt 2 - firewire 800
    3) USB3 1 - esata
    4) USB3 2 - USB3 hub - gigbit ethernet and all other USB devices
    Does this seem like a resaonable set-up in terms of maxing I/O bandwidth? My main concern is if the USB2 devices on the USB3 hub will throttledown my gigabit ethernet speeds.
    Thanks for your advice!

  • Loss 3D graphics and can't connect to external display with NVIDIA card

    I note this morning that the graphics in 3D mode of iWork (version 4.1 with system 10.6.8) no longer appears in all software suite. The 2D graphics are displayed perfectly. I also notice I can't connect an external display when I am on NVIDIA card but work well with Intel card.
    The 3D graphics are printed but not displayed on the screen (it also appear inthe thumbnail). It seems to be a worry to display.
    I posted two screen images showing the problem of 3D in Pages.

  • Connect 2 external Displays with a iMac 27''

    Hi,
    is there a way to connect two external Displays with a iMac 27inch. Eyefinity? Its a Radeon 5750 inside the iMac isnt it?

    Hi,
    For the first screen is no brainer you use the Apple adapter to have video out to HDMI or DVI, but the second screen is where it gets tricky...
    There are USB to DVI out external video cards that should work with the iMac and OS X 10.6 but I have changed. Honestly I have tested 6 so far and none of them works as advertised, you can not even set minimal resolution on there and some wont even work ( all of them come with OS X 10.6 drivers )
    So I will recommend to stay away from the small $70 or $90 external USB to VGA/DVI cards...
    (maybe someone has luck with them but i have tried like I said 6 so far different brand and no luck..)
    Now recently online I tripped over a nice external video card that takes the MiniVideo Port out from the Mac and then takes it to another 2 monitors price was $249 i think, and you could hook up 2x30" monitors with hight res... I will try to find this link and post here later on.
    Regards,

  • When streaming a movie with the new Apple TV, and using a DSL Internet connection, all audio sound works, e.g., the music track, but the audio track with the actor's voices, does not work. What can I do?

    Hi Brian,
    Thanks restoring and restarting didn't fix my problem - i have started it fresh and still it doesn't work. Basically I press ONCE on the remote, after the machine has not had any commands for 10 minutes, and the cursor skips from one end of the menu to the other - so I can't choose network or update software etc - I sometimes manage to stop it randomly in the middle of the menu if I press on a command in the middle of the cursor skipping all the menu steps...not sure what the problem is but I have basically not used my brand new apple tv since I bought it for that reason! I should call Apple support I suppose! grrrr hate wasting time with stuff like this!
    Thanks for your help though!

    Look at iOS Troubleshooting Wi-Fi networks and connections  http://support.apple.com/kb/TS1398
    iPad: Issues connecting to Wi-Fi networks  http://support.apple.com/kb/ts3304
    iOS: Recommended settings for Wi-Fi routers and access points  http://support.apple.com/kb/HT4199
    Additional things to try.
    Try this first. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
    Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
    Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
    Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

    Please read this whole message before doing anything.
    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
    Step 1
    The purpose of this step is to determine whether the problem is localized to your user account.
    Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
    While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
    Test while logged in as Guest. Same problem?
    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
    Step 2
    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
    Please take this step regardless of the results of Step 1.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
    Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?
    After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

  • My macbook pro no longer connects to my TV with the mini dvi to hdmi adapter. A while ago the computer fell down and hit the cable. How can I tell if the computer is working ok. Doesn't show mirroring any more.

    My macbook pro no longer connects to my TV with the mini dvi to hdmi adapter. A while ago the computer fell down and hit the cable. How can I tell if the computer is working ok. Doesn't show mirroring any more. Was working while watching a movie but when I pulled it out from the computer and put it back in the system would no longer mirrorr the screen on the TV.

    The best option is an appointment at an Apple store genius bar.  The evaluation will be for FREE!
