Mini DisplayPorts not functional

Hey all.
To start off here are my system specs:
Intel I5 2500
MSI Z77-G65 Gaming
MSI R7770 OC (2PMDIGD5) <-This baby of mine is the problem here I believe!
Thermaltake 450W (Litepower 450W)
8Gb DDR3 Apacer Ram
Windows 7 64Bit
Not sure what else you would like to know?
So I recently managed to get my hands on 3 23" Samsung LED Monitors so I though I would give Eyefinity a try. I bought the Active Mini DisplayPort to HDMI adapter (HDMI because I already had an HDMI cable). Sadly enough I got no signal at all from the Mini DP to the monitors (I tried 2 of the 3). I then thought it was the adapter so I bought another one, which also proceeded not to work :(. So far I have re-installed all the drivers from the AMD site and tried this card in another system that was running XP, so it required different drivers (incase the drivers had a fault...). So now I am stuck. Is there anybody who could help me here with some suggestions :D?
Oh and I am running one monitor through DVI, one through HDMI and I needed the Mini DP for the last one :/
At the moment I am even willing to buy some "Magic potion" and drink it before starting up my PC again...

ok the way you have it configured it will not like due to you using the HDMI and DVI port on the card!
for 3 you need to run DVI+MDP+MDP or it will fail! so get 2 adapters for active MDP to HDMI and put the 2 HDMI's into the adapters!
DVI + DVI + MDP is another option.
A dual-link DVI splitter cable is needed in this case.

  • IMac mini displayport not functioning...

    I recently purchased a Mini Displayport to HDMI adapter and 30' HDMI cable to connect my iMac to my 42" Panasonic TV. It worked at first, and then suddenly didn't. I believe I upgraded from OS 10.6.7 to 10.6.8 in between it working and not, could that be the problem? I know the problem is not the cable as I tested it with my XBOX. I don't have a way of telling whether or not it is the adapter itself though though. When it plug it in, there is no blue screen on the iMac like there was at first. When I click 'Detect Displays' nothing happens. Anyone have any idea what the problem might be and how to fix it?

    Try doing a SMC Reset:
    SMC RESET
    http://support.apple.com/kb/HT3964
    Shut down the computer.
    Unplug the computer's power cord and ALL peripherals.
    Wait 15 seconds.
    Attach the computers power cable.
    Wait another 5 seconds and press the power button to turn on the computer.
    The 5 second timing is important to a successful reset.

  • Mini displayport not working for DVI (VGA works)

    So I've just received my new MacBook Pro, I ordered it with a mini displayport to DVI dongle.
    When I plug this in to my known good DVI monitor, nothing happens no video is sent to the display and the preferences do not show anything.
    However when I connect using a displayport to VGA to a VGA monitor it works. I know the displayport adapter is good as I have it working on my 27" iMac.
    Could this new MacBook Pro be faulty??
    Cheers,

    Hey. I think there's a big problem with the mini displayport - DVI signal. I have a samsung T220HD monitor which worked fine with my old Macbook. I upgraded to a MBP 15" and I find the same monitor just has dead signal. Aside from the MBP itself, the differences are Snow Leopard and the mini displayport adaptor. I too ordered the adaptor with the MBP but on finding this and reading so many problems on discussions I opted to buy a mini displayport - HDMI adaptor made by NEET - which solved the problem.
    However, some wierd things happen when playing games. Resolution (which is otherwise fine) goes dark and displays ugly artifacts. This never happened with the same monitor on a DVI signal using the mini DVI - DVI. I'm guessing either all this is a Snow L prob or a mini displayport thing.
    It looks like a recent OS update (10.6.2) was supposed to fix DVI issues but apparently not for me. Apple really really need to sort this out.

  • Mini displayport not recognized in Windows 7 on MBP mid 2012

    Hi
    I have a MBPro mid 2012 with windows 7 pro installed. While i'm in windows my mini displayport is not recognized when i connect it to my smart tv. The connector i use is a Logilink Mini Displayport to HDMI. In Mavericks it works fine though. Anyone can point me in the direction of the right driver to install in windows?
    Thanks

    Hi Chocolame,
    I have the same issue as yours, and looked into this thread
    https://discussions.apple.com/thread/4904594?start=0&tstart=0
    I believe it solved their problem. I am currently downloading Bootcamp 4.0xxxx and hope it'll solve my problem.
    Give it a try and let us know if it works!
    Thanks

  • DisplayPort not functional in 2008 MP with GT120 and GTX285

    Hi all,
    I've searched the forums, but with no luck.
    I can't get any sort of signal out of the Mini-DisplayPort of my GT 120 in my 2008 Mac Pro.
    I've tried the following:
    Mini-DP to DVI adapter -> DVI -> Display
    Mini-DP to DVI adapter -> DVI to VGA adapter -> VGA -> Display
    Mini-DP to VGA adapter -> VGA -> Display
    Mini-DP to VGA adapter -> VGA to DVI adapter -> DVI -> Display
    I know some of those configurations are plain ridiculous - but what really is the ridiculous thing is that the DisplayPort just +doesn't work+.
    Any ideas?
    Could it be conflicting with the GTX 285?
    I'm running all the latest updates and drivers for everything.
    Many thanks,
    Robert

    The Dell and Sony Bravia work fine off the GTX 285, as well as the DVI port of the GT 120. It's purely the DisplayPort that refuses to play ball with anything.
    Considering how DVI-D is just DVI-D, I don't know how there can be any discrepancies between manufactures to the end result of them just not working with each other. Madness.
    I do have a Gefen DVI Switcher laying around, so I may as well use that off the DVI port of the GT 120, and switch between my third monitor (the Dell) and the Sony Bravia. I'd only use the Bravia when I'm not sitting at the Mac, so loosing a display temporarily isn't a problem.

  • IMac 2011 Mini Displayport not displaying 1080p

    Hi all,
    So my 2011 21.5'  iMac is only allowing me to display at 1080i with my mini displayport  to HDMI adapter. When I go up to 1080p the TV has no signal.
    To check that the TV was able to show 1080p, I connected it to my 2009 macbook pro and sure enough it can display in 1080p. So now I am
    sure it is not the TV, but the computer. I'm using a monoprice adapter bought in 2009 before thunderbolt was available. Could my problem be solved
    by buying an updated adapter?
    This is what I'm looking at:

  • Audio and Mini DisplayPort on Late 2009 iMac (27")

    I have a Late 2009  27" iMac and a 42" HDTV that I would love to hook up with eachother so I can start using Plex-and-the-likes on the bigger screen.
    But I'm wondering if the Mini DisplayPort of this iMac supports audio, as I do not want my sound to come from the other side of the room when watching stuff on the TV.
    I've been reading around on the net, but I can't seem to find anything conclusive that tells me that it works (some discussions and thread claim that it should work, but some official documentation regarding the Late 2009 and Mid 2010 iMacs (http://support.apple.com/kb/ht3913) only mentions the Mid 2010 one with audio output in the Mini DisplayPort
    Not sure if it matters, but I'm running a fully up-to-date OS X Lion.
    Thanks in advance.

    According to http://support.apple.com/kb/HT4241, your late 2009 iMac's displayport should support hdmi audio output, (but I have no idea whether there might be OS-X version limitations).
    Here are two attractive alternatives to the spendy apple-referenced adapters. I can't vouch for them, but they have great user reviews, and very low-risk pricing.  (I just ordered one of each to try with my MBP and new HDTV -- but neither the adapters nor the TV have been delivered yet.)
    miniDP-to-hdmi adapter from monoprice.com @ $6.65
    miniDP-to-hdmi cable from amazon.com @ $8.67
    Another interesting thought would be to skip the miniDP entirely and go with USB-to-hdmi, with an adapter that sounds almost too good to be true.  Any comments on this technology (displaylink) would be much appreciated:

  • Mini DisplayPort to DVI not working, No Multi-Monitor, Jerky Mouse

    I have an iMac, 27 inch, 2009 model.
    Until today I've had a second monitor attached via the Mini DisplayPort to DVI adapter. The monitor is a Samsung SyncMaster T260. This setup has worked perfectly well so far.
    Until today that is. Now the monitor is not recognised any more and if I try to select "Detect Displays" the mouse pointer hangs every few seconds - stops dead and then restarts again.
    What did I do to make this happen? Nothing (that i'm aware of). Haven't installed anything, not done a software update, just literally rebooted and it's not working anymore.
    _*Things that still work...*_
    The Mini DisplayPort to DVI adapter works on a Mac Mini, so that's OK
    The DVI cable works fine when plugged into a PC or Mac Mini, so that's OK
    The Monitor works fine when plugged into a PC or Mac Mini, via DVI, HDMI or VGA, so that's OK
    So I've established that, in isolation, each part of the system is functioning perfectly well.
    *_Things I have tried - without success..._*
    1) Rebooting - both iMac and monitor
    2) Unplugging all cables and reconnecting then rebooting again
    3) Clearing the PRAM - done it twice just to make sure
    4) Updated to OS X 10.6.7
    5) Reset the SMC
    6) Deleted the com.apple.windowserver.plist files at /Library and ~/Library
    7) Googled for solutions - plenty of people seem to have one or the other of these symptoms...
    Can anyone shed any light on what's happened here ? Please help!
    Cheers
    Mart
    ** Sorry if this is in the wrong place, I just found a forum specifically for the iMac so posted it there but not sure how to delete this one. **

    Well, it would be interesting if that's when it had occurred. At the time, I hadn't installed 10.6.7, and hadn't installed anything immediately prior to the problem occurring.
    It doesn't seem like there's any way (a-la System Files Checker on Windows) of checking the integrity of system files which may have been corrupted, nor a way of reinstalling any update in the case of this happening - or is there a way of doing this? You don't seem to have any control over updates apart from applying them - if something does go wrong, there's no way of backing out. I guess Time Machine is the answer to my own question there.
    I'm happy that it's working now, but it was a pretty extreme fix to have to wipe the entire system. At least it wasn't a hardware issue, I'll be thankful for that!

  • Thunderbolt display: devices not discovered after using Mini DisplayPort–to–VGA adapter

    I have an interested problem related to using my MacBook Air in clamshell (closed) mode, connected to a Thunderbolt display. The problem appears to be related to moving my MacBook air between my office and my home.
    At the office, I use the MacBook Air with an external VGA display, connected via the Mini DisplayPort–to–VGA adapter. At home, I use the MacBook Air together with a Thunderbolt display. An Apple USB keyboard is also connected to the display.
    Mini DisplayPort–to–VGA adapter implicated
    The following sequence of events causes the problem to occur:
    Use the MacBook air (open) together with a VGA display, connected via a Mini DisplayPort–to–VGA adapter (depicted at right);
    Put the MacBook Air to sleep by closing the lid, and disconnect the Mini DisplayPort–to–VGA adapter (I am not sure if the order of these two steps is significant—I usually perform them almost simultaneously when packing up my MacBook Air and getting ready to leave the office); and
    With the MacBook Air still closed, connect it to a Thunderbolt display with a connected USB keyboard.
    At this point, I would expect to be able to wake up the MacBook Air by tapping on the space bar of the keyboard. However, what I have observed is that this does not wake the MacBook Air.
    I can wake the MacBook however by moving or clicking a Bluetooth mouse that is paired with the MacBook Air.
    At this point, although the MacBook Air is awake, and the display is working, the USB keyboard connected to the display still does not work. This is the problem, in a nutshell.
    Unplugging the USB keyboard from the display, and plugging it back in causes the MacBook Air properly to identify the keyboard.
    I used Apple System Profiler to save a list of identified devices at two points in time:
    Immediately after waking the MacBook Air by moving the Bluetooth mouse (at which point the USB keyboard was not working); and
    After unplugging and plugging in again the USB keyboard (at which point the USB keyboard worked fine).
    Many devices are enumerated in the second list that are missing from the first. For example:
    Keyboard Hub@fe110000  <class IOUSBHubDevice, id 0x1000378ef, !registered, !matched, inactive, busy 3 (37993 ms), retain 6>
    AppleUSBHub  <class AppleUSBHub, id 0x1000378f2, !registered, !matched, inactive, busy 1 (37987 ms), retain 6>
    IOUSBInterface@0  <class IOUSBInterface, id 0x1000378f4, !registered, !matched, inactive, busy 1 (37986 ms), retain 6>
    Keyboard Hub@fe110000  <class IOUSBHubDevice, id 0x1000378f6, registered, matched, active, busy 0 (7 ms), retain 10>
    AppleUSBHub  <class AppleUSBHub, id 0x1000378f9, registered, matched, active, busy 0 (1 ms), retain 9>
    IOUSBInterface@0  <class IOUSBInterface, id 0x1000378fb, !registered, !matched, active, busy 0, retain 7>
    Apple Keyboard@fe112000  <class IOUSBDevice, id 0x1000378fd, registered, matched, active, busy 0 (112 ms), retain 11>
    and many child devices…
    Using the Mini DisplayPort–to–VGA adapter appears to be a necessary step to causing this problem to occur. If I merely disconnect the MacBook Air from the display, let it go to sleep, and then reconnect it again, the USB keyboard will work immediately and can be used to wake the computer from sleep.
    Some devices are discovered even when the computer is in sleep mode. This is how it should work.
    The problem appears to be that when a Mini DisplayPort–to–VGA adapter has been used since the last time the computer was connected to a Thunderbolt display, the MacBook air does not discover devices completely when it is again connected to the Thunderbolt display while in sleep mode.
    Can anyone else reproduce this problem?

    Hi glraczon.support,
    It sounds like the external display you are using (projector) operates at a smaller resolution than your MacBook Pro. You may want to configure the display preferences in System Preferences for the external projector.
    Here is an article that may help you with that process:

  • Mini-Displayport to DVI adapter not working, but Mini-Displayport to VGA and Thunderbolt work fine

    Mini-Displayport to DVI adapter not working, but Mini-Displayport to VGA and Thunderbolt work fine.
    This is a brand new MacBook Pro (15-inch, mid-2012) just received.  I suspect that this is a hardware problem as:
    The mini-displayport to DVI adapter and the external monitor that I am utilizing connect and operate just fine using my older MacBook Pro (mid-2010) with the same OS.
    The new MacBook Pro powers the external monitor with a mini-displayport to VGA adapater without issue.
    The new MacBook Pro powers an Apple Thunderbolt display without issue.
    Both MacBook Pro's are running OSX Lion 10.7.4.
    The only combination which does not work is the mini-displayport to DVI adapater used in conjunction with the brand new MacBook Pro (mid-2012).
    All adapters and components (mini-displayport adapters) are Apple retail adapter.
    I have tried several external monitors, including my Dell U2412m.
    When I connect the mini-displayport to DVI adapater to the new MacBook Pro (mid-2012), nothing happens. The external monitor reports "no signal" and attempts to go into sleep mode.  Using the "Detect displays" button has no effect, even when used multiple times.  Rebooting does not help, nor does resetting the SMC or PRAM.
    Any other suggestions before I take it to the Genius Bar?

    I turns out that the logic board of my MacBook Pro was faulty (despite being brand new).
    I took it to the Apple Store, presented the problem, and one of the Tech's came to the same conclusion that I had -- hardware failure.  Phone support was no help in the matter (and even told me that what I was trying to do wasn't a supported option, which is rediculous).  However, the Genius Bar did take care of the problem, and my MacBook Pro was back to me with a replaced logic board within a few days.
    Hope that htis helps.

  • Mini DisplayPort to VGA adapter not waking monitor

    Hi,
    I've had my Mac mini for about a month now (the 2010 model with 2.4GHz Core 2 Duo and 2GB of RAM). Initially I had it connected to a 32" TV via HDMI which worked perfectly. However I have now switched to a 24" Iiyama ProLite E2410HDSD which doesn't have a HDMI socket. I've bought a Mini DisplayPort to VGA adapter.
    Whenever I put the mini to sleep or switch it off, the display does not come back on. To get it to work, I have to unplug the adapter from the mini and plug it back in again. Is there any way to get it to work all of the time?
    Thanks,
    Thomas
    Edit : Just booted into Windows 7 using Boot Camp, and putting that to sleep and waking it works perfectly!
    Message was edited by: thomasw234

    I think I know what's wrong, but I don't know of a good way to fix it. The Iiyama is not constructed correctly. It appears that it's DDC channel goes down when it's sleeping, which it shouldn't do, unless it allows auxiliary power on the VGA cable to keep the channel active, which it also seems like it isn't doing.
    Does the Iiyama have a DVI input? That might work better with the correct adapter. Although if they messed up the architecture of the VGA port, they may have messed up DVI, too.

  • Mini DisplayPort to VGA adapter not working under Vista (Boot Camp).

    Hi there,
    I'm facing a very serious issue with MacBook Pro Unibody running MS Vista under Boot Camp: using the Mini DisplayPort to VGA adapter to hook a projector is 95% impossible because the only resolution available is 640x480 or sometimes 800x600. No solution came from the adaptor firmware update, still same behavior: connecting the external projector/monitor toggles 640x480 resolution with no more choices available. Just 5% of attempts on selected projectors gave me access to the complete resolutions list.
    This is having a serious impact on my job where I do need both Mac&Windows running natively and with external display capabilities, please I'm looking for some feedback from users facing the same problem or someone who had an official answer on this issue from Apple. Do avoid posting about using modded display drivers please: I know they exist but the adaptor should be working with original ones.
    I can understand Apple does not support MS Vista issues but this seems to be a hardware/driver one.
    I'd like to point out I'm using a clean Vista installation with Apple drivers (from the Leopard DVD) and I've run Vista (same version, same gfx drivers etc) under Boot Camp on my previous MPB (with integrated DVI output+adapter) on hundreds of different projectors with never a single problem.
    Any feedback is really appreciated.
    L.

    I'm having the same problem. When I try to connect to the switch in our conference room (connecting both a flat panel display and/or a projector, both with much higher native resolutions), all I get is 640x480. This is a huge problem to using bootcamp, and I really need to get this to work. I was able to get a higher resolution 1280x800 on a separate, portable display, so I'm wondering if people have the problem with standalone projectors or only with projectors connected to some sort of switch, in my case an Extron MPX423A. I have also tried this in both Windows Vista (32-bit) and Windows 7 RC1 (32-bit), with the bootcamp drivers and the latest NVidia drivers, and the behavior is the same all around.

  • Mini displayport to VGA not working anymore

    Hello Everyone,
    Macbook Pro 10.9.5 Mavericks
    Mini displayport to VGA adapter to beamer
    I recently bought a mini displayport to VGA adapter cable to use my beamer as an extra display.
    The first 24 hours it worked and I could use the beamer as an external display which was great.
    Only the next day it wasn't working and the beamer kept saying NO INPUT. My roommate has a windows laptop with VGA port and it still works on his laptop (before the incident and after).
    I used the same cable only with the mini displayport to vga adapter inbetween it.
    I tried everything to solve it.
         - Go to display and look for external desktop of mirroring (this didn't work because my macbook doesn't recognize it)
         - I did a PRAM reset   
         - Did a SMC reset.
         - Tried the same thing on another beamer and it didn't work. With my roommate (his laptop) everything just works.
         - and finally i bought another more expensive Apple mini displayport to VGA adapter and it didn't work also
         - I repeated al the previous steps with the new adapter (PRAM, SMC, DIFFERENT BEAMER, DIFFERENT CABLE)
    Still it doesn't work.
    I really don't know what to do now. I just worked the first day and know my macbook doesn't even recognize it. doesn't matter which of the 2 ports (on my macbook) I use.
    I hope there's is someone with a solution because I just don't understand why it's not working or ignoring my cable.
