HDMI to DVI Problems (Detailed in Post)

I have two brand new Core i5 Mac Minis running Snow Leopard.  They shipped with the usual HDMI to DVI adapter, to which I plugged in an HP S2031 displays; however, OS X is detecting each display as two separate displays.  In addition, if the computer goes to sleep at any point, the HDMI port will stop working alltogether until the computer is restarted.
I tested it with an Asus 19" display and a Dell 20", and the same thing occurs, so it's not display-specific.
Any thoughts, comments, or suggestions?

I just installed the 10.6.8 combo update to be sure I have the latest drivers, but no luck.  Also zapped PRAM, but that didn't help either.
Monitor remains responsive if only the display goes to sleep, but if the whole computer sleeps, then the HDMI stops sending a signal.

  • Static using HDMI to DVI adapter on 2011 mini

    Hi,
    I bought my first Mac last week, the i5 2.3ghz mini.  I originally set it up on my TV (using HDMI), downloaded/installed the updates, and messed around a bit before deciding that a 42 inch display isn't as convenient as I thought it would be.
    Using the HDMI to DVI adapter that came with the mini I hooked it up to my 19 inch acer monitor.  While booting  can see the boot screen, but the display is very staticy.  Once it logged in I was able to barely see well enough past the static to mess around with the display settings thinking that maybe the mini was trying to push an unsupported resolution to my monitor (because I set it up on my TV at 1080p).
    I read up on the issue and it seems that some have had problems with static while waking up from sleep.  Mine has static all the time.
    By a stroke of luck I happened to have a HDMI to DVI cable on hand.  I tried it out and it displayed beautifully.  No static, works as I expected.
    So the problem seems to be the adapter that came with the mini, the DVI cable that I was originally using (the cable works with my PC), or the HDMI port on the mini itself not working well with Apple's own adapter (not likely).
    I was just wondering if anybody else has had this issue, and if they fixed it did it end up being the adapter or did replacing the DVI cable with a higher quality cable do the trick.
    Thanks,
    Corey

    I just posted a similar issue here. The weird thing is that on my system, a Dell monitor works with the HDMI-DVI adapter but the Acer monitor doesn't. Do you think getting another adapter would resolve it fo rme? What kind worked for you?

  • HDMI and DVI port not working on 880GMA-E35

    Hello,
    I want to use the HDMI port of my 880GMA-35, but the monitor is not getting a signal. I know that the board has two jumpers to switch between the DVI and the HDMI port. In the delivery state the jumper is set to HDMI, but I don't get a signal. There is also no signal, if I switch the jumper to the DVI pins. I have tested this setup which different cables (HDMI and DVI) and two different monitors.
    After this test I get a guarantee replacement of the board. The new board is also not working with HDMI or DVI. The VGA port of the first board was working as supposed and I don't see any Bios settings to activate the monitor ports.
    Are there any suggestions to solve my problem?
    Thanks in advance and kindly regards
    Daniel

  • Using DVI to VGA adaptor with HDMI to DVI port on Mac Mini Server

    Hi - I couldnt find anything on this, so I decided to post a new topic. We just recently purchased a Mac Mini server at work for iOS development. Before we launch in in one of our data centers and start remoting into the system, we need to conduct basic setup on the system.
    For this, we pulled out an old stock VGA montior we have around the office, and found an apple DVI to VGA adaptor (http://i51.tinypic.com/2mzb4lc.jpg)
    The problem is, the pins dont exactly line up... on the DVI to VGA adaptor there are 2 extra pins above and below the horzontial pin on the left hand side (http://i52.tinypic.com/2mxhg1j.jpg) that do no exist on the Mac Mini HDMI to DVI adaptor (http://i53.tinypic.com/2ywesrp.jpg).
    Ive checked other converters and it seems that all of them are setup the same way, with two pins above and below.
    Has anyone else had to deal with this issue? I really dont want to go and buy the Mini DisplayPort to VGA adaptor for one-time use.
    Thank you!

    Welcome to  Discussions!
    What you are seeing is the difference between an analog and digital DVI connector, as DVI as a specification can provide both types of signal, depending on implementation. When used in a mode where only one or the other type of signal is provided, the different connectors prevent a mismatch. VGA being analog, the DVI to VGA adapter is using an analog DVI connector. The other connector you are dealing with is a digital only connector. HDMI is digital only, hence the HDMI to DVI adapter being digital only. Thus you can not adapt from the HDMI port to VGA with just passive adapters, you would need a conversion device between. It would be cheaper and more effective to use a Mini DisplayPort to VGA adapter.

  • HDMI to DVI No Signal Detected

    I have a late 2006 MacBook Pro running OS X 10.6.6. I recently purchased an LG LED-LCD television as well as a HDMI to DVI adaptor cable, both from Amazon (the cable is an Amazon Basics cable). When plugged in to both the laptop and the television, there is no signal detected by the television and no display detected by the laptop. I've tried each of the three HDMI ports on the television, but to no avail. I returned the cable and exchanged it for an identical one, but the problem persists.
    In searching through the forums, I've seen that quite a few people have had issues with this same setup, and I'm wondering if somehow I need more than just the cable to connect to my television (which doesn't make sense, but could still be the case). I've run a diagnostic on my laptop during startup, and found no issues with the hardware, so I'm 99% positive that I don't have a bum DVI port. At this point I'm just not sure what to do to get this to work, so any assistance would be wonderful.

    Sorry for any confusion, my last post was sent before reading your second post.
    The VGA test proves nothing about the DVI output. The DVI ports on these Macbook Pros is a combo DVI and analog VGA port (DVI-A). The DVI-VGA adapter does nothing more than connect the VGA to VGA, and does not convert the DVI to VGA. You have to use an actual DVI device to test the DVI. The 4 pins and large blade on the end of the DVI connector are the VGA pins - they can be omitted on a DVI-HDMI adapter with no harm.
    I really don't know if there could be a problem with the software on the Mac and/or TV, and the cable just fine.
    Perhaps try to seek out someone who has a working DVI-HDMI cable to try? Or try a store that will demonstrate that it works and has a money back guarantee?

  • DVI-D - HDMI switcher - DVI-D

    Hey friends,
    I've got a fairly convoluted and confusing HDMI situation. As DVI matrix switchers are so expensive, I decided to get a HDMI switcher and HDMI to DVI cables. I have two Mac Pro towers, each with two DVI outputs, and two 24" Cinema HD displays. So, my signal flow is:
    Mac Pros - DVI to HDMI cables (x4) - HDMI matrix switcher - HDMI cable - HDMI to DVI adaptor - Cinema HD tail
    The monitors simply flash three short lights, which Apple support tells me means that they are recieving an invalid format or resolution. I thought that HDMI and DVI were completely compatible formats... Any ideas as to why this is not working?
    Thanks!

    Going through a lot of "adapters" in that setup (cables "adapters", switcher, dvi adaptor).  I guess my first question would be to supply all the details of all those components to verify they are the proper components to handle the signals.  So, list url's to all the stuff:
    1. dvi-to-hdmi cable
    2. hdmi switcher
    3. hdmi-to-dvi adaptor
    4. hdmi cables (including lengths)
    Maybe there's something in the specificaions of these things that would indicate the problem.
    Update:
    As an experiment you might want to try a single monitor and macpro without the switch.  mac pro --> dvi-to-hdmi cable --> hdmi-to-dvi adaptor --> monitor.  If it works then obviously the switch would be the culprit.

  • HDMI to DVI

    Hi,
    I just ordered a recent MacMini with HDMI and Thunderbolt. I already own an older Apple Cinema Display (2005, I think 20'') with a DVI port. Will I be able to connect this display to the new mini via the HDMI to DVI adapter, or do I need to buy a DVI to miniDisplayPort adapter seperately?
    Thanks for your help!
    Best,
    Phil

    Hi Ddre2k
    Phil has an older 20" Apple Display.
    Perhaps you should be asking Apple why the 2012 Video Support spec's are not clear.
    Examply: the spec for previous 2010 and 2011 models clearly report 1920x1200 support from the HDMI port.
    2010
    2011
    If you are having problems with a monitor or connections? You should start a new thread, giving more details about which Mac Mini and exactly what 27" monitor you have, so that we can clearly answer your questions. 

  • Satellite A205: Dynadock - How to connect to LCD TV with HDMI to DVI cable

    I recently purchased this product and had a problem when connecting it to my LCD TV.
    I used a HDMI to DVI cable to connect it to the TV. Only a small portion of the full display shows on the TV.
    I have adjusted all setting on the laptop (Satellite A205) but it only adjusts the laptop screen, not the TV.
    I also used the adaptor to VGA, plugged it into the computer input on TV, same effect. I can use VGA output on side of laptop to TV ok.
    Any ideas on how to adjust dynadock output settings?

    First of all it would be interesting to know what dynadock you have exactly; one with DVI port or one with VGA port?
    >I have adjusted all setting on the laptop (Satellite A205) but it only adjusts the laptop screen, not the TV.
    You should know that the dynadock has a own built-in graphics controller and video drivers to control the video stream.
    Therefore you should change the settings directly in the dynadock settings and not on the laptop!!!

  • 2011 Mac Mini and Acer x222w monitor incompatible? HDMI to DVI adapter issue

    I am totally bummed because I just bought a new Mac Mini thinking I'd be able to use the display from my old system, an Acer x222w, which has both DVI-D and VGA connections. I hooked the monitor up using the HDMI to DVI adapter included in the box with the Mini. On boot, I could see the Apple logo, though it was not centered, and when the set up screen came up to the select language screen, it flashed quickly and then turned to snow.
    I was on the phone with Apple support for over an hour trying to troubleshoot this issue. I was a little disappointed that tech support didn't even seem to  be aware that the Mini came with an HDMI to DVI adapter. It was then recommended that I try an adapter for the mini display port, which the 2011 Mini doesn't have.
    I was able to borrow another monitor, a Dell with DVI-D, and it worked.
    I have searched for specs/requirements that might explain why the Acer monitor doesn't work while the Dell one does. I cannot find anything from Apple. I just assumed any DVI connection would work. Has anybody else encountered this problem? Most of the issues I've found on the forums involve trying to hook up to a home theater LCD TV, which I'm not trying to do. If I had known my monitor wouldn't work, I probably would have just saved up for an iMac.
    Thanks in advance for any thoughts or tips!

  • Mac mini display is flicking via HDMI to DVI adapter and DVI cable

    i have received mac mini server (mid 2011) recently. mac mini is connecting the display via HDMI port using DVI cable with a HDMI to DVI adapter.
    the display shows constant flicking. white dots/lines show randomly. it is like those signal noise when watching analog TV.
    the same display works fine and well with macbook pro (early 2008) via DVI port.
    please help. please advise.

    So you know the display is working.
    It seems to me you have a few possible problems.
    1 HDMI-DVI cable is bad
    2 DVI-cable is bad
    3 Connections between cables or computer or monitor are bad.
    4 HDMI port on the computer is bad.
    I assume you've tried #3, and re-connected cables and wiggled inputs.  So then try replacing 1 and then replacing 2 which are cheaper fixes than replacing/fixing 4.........
    FYI, I'm connect my mac mini using the same setup you describe, with no issues....also inspect the cable ends carefully to look for any problems.

  • No HDMI or MiniDP-to-VGA output, but HDMI-to-DVI is okay

    I purchased my Mac Mini almost a week ago and I've been having strange issues with getting my various monitors to work with it.
    I don't own any Thunderbolt or native MiniDisplayPort monitors, however I do have a number of VGA monitors, as well as some HP LP2475w monitors which have VGA, DVI (DVI-D and DVI-A), HDMI, and DisplayPort inputs.
    When I have OS X installed on my Mac Mini, the Apple MiniDP-to-VGA adapter works with my VGA monitors, but only when OS X has loaded. My monitors all say "no signal" during the boot-up phase. However I had no problems when I connect my LP2475w monitors to the Mac Mini via the HDMI-to-DVI adapter: I see the grey screen during bootup, can see/access the boot menu, and everything works fine.
    Today I purchased a HDMI cable to connect the Mac Mini to my LP2475w monitors to see if that would work. Well, it does work... almost, sometimes, but not most of the time.
    When I use a direct HDMI connection my LP2475w says there's no signal, unless I plug the cable in during the text-mode portion of Windows' bootloader (under Boot Camp). As soon as Windows loads, or during the grey-screen bootup section my monitors all say there's no signal. There is nothing wrong with the cable or my monitors.
    Here's a table:
    Connection
    Can see boot screen/boot menu
    Can see OS X (when loaded)
    Can see Windows (when loaded)
    HDMI from Mac Mini to LP2475w
    No
    Not tested
    No
    HDMI-to-DVI from Mac Mini to LP2475w
    Yes
    Yes
    Yes
    MiniDP-to-VGA from Mac Mini to VGA monitor
    No
    Yes
    No
    So what's going on here then?
    Has anyone else had the same problems as me?

    SOLVED - I purchased a third-party MiniDP to DVI adapter instead and it works a treat.
    Quite what the difference can be to a supposedly passive adapter I'm unsure - but glad it's fixed anyhow.

  • No signal apple tv3 to projector via hdmi to Dvi-d

    I have a 3rd gen Apple TV. Works great on my 1080p tv, with optical out to my surround amp. When I connect to my Panasonic pt-ae500 720p projector via hdmi to dvi-d I get no signal at all. The projector is HDCP compliant and I can connect my ps3 to it at 720p no problem.
    I have tried changing the edid settings on the projector, and changing resolutions on atv.
    Any suggestions? I really need to set up my home cinema incorporating ATV
    Thanks
    Steve

    It's an inherent problem between the ATV 2 & 3 and certain older models of TV / Projectors. Something to do with negotiating the signal between the two devices, the ATV falls over.
    I also have this issue. I dug out my old PT-AE500 only to find that my ATV 2 was getting stuck on the Apple logo. No solution yet though, unfortunately.
    There is another (old) thread on it here: https://discussions.apple.com/thread/2631562?start=0&tstart=0
    There are a couple of ideas there, one of which was to switch the ATV on *before* plugging in the HDMI cable, let it boot up (give it 2 mins or so) then plug in the cable. This solved it for one person on that thread, but I can't get it to work here! I'll give it another try.
    It's only the Apple Tv that has this issue as well. My MBP, Mac mini, etc, work perfectly. Just inconvenient having to lug them to the projector each time we want to watch a movie
    Sorry I can't be of much help, but maybe have a read through that thread to see if any of the tips there work for you.
    I'll also report back if I manage to find something that DOES work!

  • HDMI to DVI adapter not allowing full resolution when using Mac OS but does with Windows 8.1

    I have a Mac Mini and using the HDMI to DVI cable that came with the computer the maximum resolution it will allow is 1280 x 1024. I have 2 of the same monitors. The other is connected with DisplayPort to VGA adapater and displays full resolution (1920 x 1080) on both monitors but the HDMI to DIV will only show 1280 x 1024.  I thought maybe it was my DVI cable or the adapter but when I boot up in Windows 8.1 through bootcamp both monitors display at full 1920 x 1080 resolution. Why does Windows give me the option for full resolution on both but the Mac OS doesn't? All the latest updates have been installed. I've contacted support and all the things they had me do didnt work. I see all these posts with people complaining about the same resolution issues. Is it that difficult for this to work?

    Humm... the dual Samsung 21.5" monitor setup on my 2010 Mac Mini running Mavericks works a expected.One is on the HDMI to DVI adapter and the other in on a Kanex Mini DisplayPort to DVI adapter.
    Try > Display Menu from the Mac App Store and see if you can select 1920 x 1080 for both monitors using it.
    Addtitionally, are you sure that it the HDMI to DVI monitor that is not getting the correct resolution...? Most people are complaining that it is a VGA connected monitor that is not getting the correct resolution.
    If it turns out to be VGA connected monitor, then try using a Mini DisplayPort to DVI adapter and DVI cable for that monitor instead of VGA.

  • Lenovo K1 1304 Tablet - Micro HDMI to DVI No Signal

    Hi,
    I'm having a problem here. I want to connect my Lenovo K1 tablet to a TV or monitor with DVI input using HDMI cable and HDMI to DVI Adapter. This should work perfectly fine since both hdmi and dvi are backwards compatible with each other and I've succesfully connected a different tablet like that before, yet I get no signal when trying to output a video from Lenovo K1 Tablet.
    Micro HDMI output port on my K1 works fine since I can output signal to HDMI input on my TV but not to DVI input using HDMI to DVD Adapter and like I said this should work just fine.
    Any ideas anyone?
    Thanks.

    It doubt the adapter has to be HDCP "compliant", because it should just provide a mapping of pins/wires from HDMI to DVI, so any handshaking would occur between the endpoints (tablet and display device).  In case it helps, here's the pin mapping:
    http://pinouts.ru/VideoCables/hdmi_dvi_cable_pinout.shtml
    There are some different flavors of DVI, such as DVI-D versus DVI-I, with single or dual links - is it possible that there is a mismatch between adapter, cable, and device?

  • HDMI to DVI-D

    Hi,
    I'm trying to connect an external HP 2510i (WD005AA) monitor to my M6-K125DX HP Envy notebook. I'm using an HDMI to DVI adapter cable but the monitor says it does not receive a signal. The display shows no image en after a while, the monitor goes to the standby mode. 
    First i returned the cable to the supplier, but the new cable they send us gave the some results. According the specifications of the monitor it is equipped with a DVI-D input.
    Do i need a special cable or adapter to connect this monitor?
    Could this be cause by single-link or dual-link capabilities of the laptop or monitor?
    Hope you can help me out.
