MDP - DVI adapter and HDCP

I have a mini display port to DVI adapter connected to a View Sonic vx2439wx. When I try to play DRMed content in iTunes on that screen I get an error that the display is not HDCP compatible. If I move the playback to my second monitor (a Dell 2007FPW) which is connected via a straight DVI cable, the video plays back fine.
Does the MDP not support HDCP?

Are you sure the display is HDCP compliant? There is no mentiion of HDCP in its spec sheet.

If I move the playback to my second monitor (a Dell 2007FPW) which is connected via a straight DVI cable, the video plays back fine.
That one does say it supports HDCP.

Does the MDP not support HDCP?
It supports HDCP. Here is an adapter that mentions HDCP:

The Apple version doesn't mention HDCP, but here is someone who got HDCP working with it:

  • 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.

  • Macbook (late 08) 13.3" -- miniDV to DVI adapter and Dell 24" 2405 FSP Flat

    All
    Just purchased a Macbook 13.3" and bought the miniDV to DVI adapter for my 24" Dell 2405 FSP. For whatever reason, I cannot get system prefs to "detect display".
    I am not sure if the cable is broken out of package or there is a problem with this adapter in general. I am trying to use the cable to view OS/X and XP Home via Bootcamp on large screen while Macbook is in clamshell (closed) mode.
    Seems like a lot of people are having issues but I don't know what to do. It seems the cables from Apple vary by model and worse, appear to be lower quality than most would expect. Any thoughts on commands or steps to try and diagnose. Or should I buy the miniDV to VGA adapter for the Dell flatscreen?

    Update to this issue.
    1. Friend brought his Macbook Pro 17" with full DVI adapter to my Dell 2405 FPW -- he has same 24" flatscreen. It works -- so monitor is fine.
    2. I went to Apple Store and REPLACED miniDV to DVI adapter to my monitor. No response. Not registering at all. But when friend hooked his Macbook with adapter, the screen came on.
    Assumptions:
    1. Macbook 13.3" aluminum port is damaged -- will go to Apple to confirm
    2. Odds of two adapter cables not working - highly slim (got from two different stores if we want to shake the odds a bit more based on batch shipments
    It appears that the port is NOT compatible with this monitor OR the cable quality is so bad that I have to go through a bunch of them.
    Last option - miniDV to VGA adapter to my Dell monitor to see if that works. But it is one of two options -- from my perspective:
    1. Monitor/port incompatibility
    2. Bad cables
    I even tried XP Home Edition under Bootcamp with the adapter and monitor did not display.
    What's disappointing in all of this is Apple tech support told me to download "drivers" from Dell's site -- and puzzled, I asked if Dell was supporting Mac computers because OS/X did not have drivers for this monitor and Dell only has it themselves - they emailed me download links (which is convenient) but it was clear that she doesn't know what she was doing -- the links were XP and Vista only.
    Sigh...Rev A Macbook. Will probably need Apple to work on this issue.

  • Mini dvi adapter and long cables. Weak signal?

    Hi. I'm having a big problem with my Macbook and a projector (a cinema theatre projector to be more accurate). The projector stays 10m away from the computer. The screen flickers all the time, and colors doesn't appear right. I already spent so much money on this. So this is my setup:
    Macbook (i3, 2013) > mini-dvi to hdmi adapter (not from Apple) > 10 meters hdmi cable > hdmi to dvi-d adaptor.
    What I've tried so far:
    3 other mini-dvi adapters. None of them are from Apple (I know, that may be the problem). DIDNT WORK
    Shorter cables. It got better. No more flickering. But still a lot of color distortion. DIDNT WORK
    Windows computer. Was still flickering. DIDNT WORK
    Windows computer with a smaller cable. WORKED
    Different longer cables. All of them gave me the same flickering. DIDNT WORK
    TV (instead of a projector) with a small cable and the same adapter: WORKED
    BLURAY + long cable + TV: WORKED
    Different hdmi to dvi adapter: DIDNT WORK
    I'm really stressed out with all of these. The last theory I have is that the non original mini-dvi adaptor has not enough signal for a long hdmi cable. Anyone knows anything about it?

    Update:
    The same macbook, the same adapters and the same 10m cable connected on a TV. WORKED!
    Now this is really strange. Is there any chance that the cinema projector will need more signal strength than a normal TV would?

  • Dual-DVI Adapter and Windows 7

    Just under a month ago we have purchased a new mac mini that's running Windows 7. Mac mini is now connected to a 29" UltraWide AOC Display using a Dual-DVI link adapter. Everything is working okay in terms of resolution, but the screen cannot detect input after Windows 7 boot screen.
    When you first switch on the mac, you get the Windows start up and then it goes to a black screen. The monitor displays no signal on DVI and goes to standby. We have to unplug the DVI adapter from the thunderbolt port and plug it back in, for the monitor to come back on.
    Any ideas what could be wrong? Do we need a special driver for the adapter?

    As previously stated mount # and chroot in the install grub to /dev/sda mbr - nothing will be lost from your hdd and grub will boot in preference to winloader
    Use the the beginners guide for the commands and adapt for your system
    https://wiki.archlinux.org/index.php/Be … ase_system
    https://wiki.archlinux.org/index.php/Be … bootloader
    ... and always install windows first - if you did a clean windows install it may be best to install all the service packs / major updates before bothering to reinstate grub as you may find you need to repeat the process anyway

  • Apple MiniDisplayPort to Dual DVI adapter and 30" displays

    Hi all,
    I just purchased a DoubleSight DS-305W 30" display only to learn it doesn't work with the Apple MiniDisplayPort to Dual DVI adapter. I had the flickering issues described in length here:
    http://store.apple.com/us/product/MB571Z/A?mco=MTY3ODQ5OTY
    I thought it was the adapter firmware issue, so I drove 3 hours in the snow to the Apple store to get a replacement with the new firmware (1.0.3). After doing so, the issues persisted.
    I am now wondering if anybody has experience with other 2560x1600 monitors and this adapter. I am considering buying a NEC LCD3090WQXi-BK -- has anybody tried this one? Thanks in advance.

    My apologies for reading your mail after almost 2 years !
    Perhaps my reply may still have some relevance after 2 years. I am using HDMI to DVI connector to connect my Mac Mini Mid 2010 to Samsung XL2370 Monitor.

  • Mini DisplayPort to DVI Adapter and macbook pro

    I have a 2010 macbook pro 13", samsung 20" LED display connected via mini display port. The setup has been fine for a few months but occasionally both displays would turn blue as it tries to detect itself(I assume) when this happened I would just need to reset to fix itself. This week I used my laptop away from the screen for a while, once I connected it to the display the blue screen has become more prominent, it would blank out for no reason intermittently and has become progressively worse. I've tried shutting down, cleaning the mini-display-port, resetting PRAM and now I'm out of ideas.
    Could it be related to the new EFI firmware update v2.5? that was the last major update installed.

    You might be better off taking the computer and the display into a Apple Genius Bar annd showing them what is happening.
    They may have a fix or maybe something needs to be replaced.

  • Included Mini-DVI to DVI adapter does not support HDCP and iTunes HD movies

    Hi.
    Just downloaded Twilight in HD (to own) from the iTunes Store and had the annoying message about HDCP not being supported by my display, and that I could not play the movie in HD.
    My Mac Mini is plugged to a very HDCP-compliant Sony Bravia 40" LCD TV via Apple's mini-DVI to DVI adapter (included in the new Mac Mini's box) and a DVI to HDMI cable.
    (HDCP works well for this TV with a PS3, another Sony Blu-Ray player (the 2 are for zones A and B), an AppleTV)
    Since I have other recent Macs with a Mini DisplayPort, I happen to also have an Apple branded Mini DisplayPort to DVI adapter.
    So I replaced the (mini-DVI to DVI) adapter by the (Mini DisplayPort to DVI) adapter and plugged it on the Mini DisplayPort on the Mac Mini.
    I can now play the HD version on my Sony TV!!
    This really sounds like a joke!
    A joke that is going to make me go the shop and buy another (Mini DisplayPort to DVI) adapter, since I like to always have one, as well as the VGA adapter, with my MacBooks.
    Let's hope there will sonn be an iTunes, Leopard, or mini-DVI to DVI adapter firmware update very soon to fix this.

    I am actually very surprised that your miniDisplayPort to DVI transition works with HD content.
    I'd consider that a bonus and cherish it until Apple removes that functionality in a future update.
    It is probably a bug as it should not work.
    The thing to keep in mind is that DVI cables do not support the necessary DRM/encryption signals for HD video content.
    This is one of the main reason DisplayPort was introduced.
    So I am not surprised that miniDVI to DVI to HDCP does not play HD content on your TV.
    In fact this is +expected behavior+ due to the lack of DRM/encryption signals.
    No matter how you convert from miniDVI to DVI, the port cannot create something that it doesn't have in the first place.
    The more I am surprised that the miniDisplayPort to DVI to HDCP transition provides these signals. I would have expected them to be filtered out in the DVI cable in the middle as this cable cannot pass something on that DVI is not designed to carry (HD DRM/encryption signals).
    It could very well be a 'bug' in the miniDisplayPort to DVI cable controller, which Apple might 'fix' in a future driver update.
    It is likely a mistake that this works.
    What you really need is a miniDisplayPort to DisplayPort to HDCP conversion. Or directly a miniDisplayPort to HDCP cable. Those are the only routes that are guaranteed to work passing HD video DRM/encryption signals along.
    But as far as i know neither of these two cables are available yet.
    Which might be the reason why Apple - for the time being - allows your miniDisplayPort to DVI route to work. Emphasis on +for the time being+.
    I would not count on the fact that this will work forever.
    And I would certainly not count on a software update that will make the DVI route work. This will never work due to DVI's incapacity of providing DRM/encryption signals for HD content.

  • 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.

  • Problem using mDP-DVI-D adapter.

    Hi!
    This is my first post on this forum since I just bought my very first mac! Everything has been painless until today.
    Since I had a DVI-D - HDMI cable from before (which I used with my old PC to connect to my TV) I figured I'd go and buy myself the DVI adapter.
    The problem is, after everything is hooked up and ready to go, I get no picture at all on my TV.
    BUT my macbook do find it and recognize it in the OS.
    There's nothing wrong with the cable since I tried connecting it to my PC again and I've also tried another DVI-DVI cable. I've also tried two different
    TVs (one LCD and one plasma, both Samsung) and also an ASUS LCD desktop monitor. The problem occurs on all the monitors.
    On the monitor settings I do see that it has found a Samsung TV or whatever external monitor I'm using, I can change resolutions, switch between mirror and extended desktop and I can also move the cursor outside the windowframe where it would show on the external monitor if it had any picture.
    I've read a couple of posts here and also googled it but is it safe to say that there's something wrong with the brand new adapter I bought or have I missed something?

    Macbook Pro 13" 2.3GHz - 2011

    As I suspected it was a faulty adapter, went and returned it to the store and bought Apples own DVI adapter and it works!

  • Mini Display port DVI adapter not working on Thunderbolt Port

    For some time I've been using a mini display port to DVI adapter on an slightly older MBP to connect to my HD TV.  I recently purchased a MBP with a Thunderbolt port and when I try to connect it to my TV via my mini-display-port-DVI adapter things are not working properly.  The MBP is seeing the Philips TV but it isn't listing all the display modes and I'm not able to send any video to it.  Does the Thunderbolt port require a new display port to DVI adapter?

    Let me be clearer; I've got the MDP-DVI adapter connected to a cable that is DVI on one end and HDMI on the other.  I've got both laptops so I can compare side by side.  I plug in the MDP-DVI adapter to the old laptop and all works well; I plug it into the new laptop and while the laptop does see the TV, the display modes for it are all 1080p which is wrong I don't see any desktop image on the TV unlike when I plug it into the older laptop.  This is very disappointing as I expect things to just work with Apple products.

  • Does Mini Displayport to DVI adapter support analog VGA signal?

    I'm just about to buy a macbook pro. Since the MDP (mini displayport) to DVI and MDP to VGA adapters are £20 a pop, I can only afford to get one. Obviously DVI is better in general, but VGA supports more older hardware, CRTs, and the spare VGA input on one of my displays (where the desktop uses the DVI).
    What I'd like to know is does the MDP to DVI adapter also support the analog VGA signal on certain pins (like most physical desktop DVI ports do)? If it does, since I have about 3 or 4 DVI to VGA adapters lying around, I can get the MDP to DVI adapter and use the DVI to VGA adapters with it if necessary, but if it doesn't I might be better off getting the MDP to VGA...

    No. Unlike DVI, which in the DVI-I configuration has both digital and analog pinouts, DisplayPort (and mini-DisplayPort) are purely digital. Mini-DP to DVI then DVI to VGA will not work. If you look carefully at the Apple Mini-DisplayPort to DVI adapter, you'll notice it's a DVI-D connector - digital pins only.
    The Apple mini-DisplayPort to VGA adapter contains a digital-to-analog converter.
    So, you'll have to choose. If you want VGA, get Apple's mini-DisplayPort to VGA adapter.

  • HDMI doesn't work, but MDP- DVI- HDMI works

    Hello!
    I just got my new Mac Mini and tried to connect it to my TV (a Samsung LE22S8) over HDMI, but this doesn't work since the TV reports "unsupported resolution" (it's the TV's native resolution of 1680x1050, where I also checked all frequencies using an external program and they are as written in the manual of the TV).
    However when I connect the TV over a Mini Display Port to DVI adapter, and then use a DVI to HDMI adapter (so that the TV is still using the HDMI input) it works fine.
    So what's the difference between MDP->DVI->HDMI and HDMI->HDMI (all resolution and pixel frequency settings are identical)? What can I do to get the HDMI->HDMI solution working?

    It also appears that there is no conversion when HDMI-video is extracted from DVI, only that the pins are shuffled.
    If direct DVI works on that port, then HDMI-video with an adapter should work as well. As I mentioned above, VGA is present on DVI-I ports on a separate set of pins, and VGA working or VGA not working has no bearing on your problem.
    If a Mini DisplayPort is involved, the most common issue is that the Mini DisplayPort connector is not inserted firmly enough. It has a lot of pins and you have to press hard to seat it.
    Other possibilities are that the resolution you selected is beyond the capability of the display device, or that the adapter is bad.
    Is this the stock display card, or one you added later, and what model?

  • Use Mini DisplayPort to DVI adapter to connect Mac Mini to Cinema Display?

    Hi
    I have a new-to-me current model Mac Mini and want to use it with my 20" Cinema Display (model A1081).
    The Mac Mini instructions say to use the HDMI port on the Mac Mini with a DVI>HDMI adapter cable. I seem to have only a DVI>Mini DisplayPort adapter cable. I'm guessing this will be OK to use, but don't want to fry the system straight out the box
    Can anyone confirm it's OK to use DVI>Mini DisplayPort connection to drive the display?
    TIA
    Jim

    Thanks for the reassurance BSteely!
    One thing I've seen when rummaging through the forum is a suggestion that with MDP>DVI adapter is problems with display waking from sleep. Short of setting it not to sleep, is there a workaround to wake it up again if it doesn't respond to usual stimuli?
    TIA

  • HDMI/DVI adapter problem?

    I've had the 1st gen Apple TV since it came out and have loved it. It has worked fine on my 5 year old Sony HDTV. Since this tv does not have HDMI inputs (has an DVI input), i used an HDMI/DVI adapter and this worked fine up till now.
    Yesterday i got the new apple TV and tried hooking it up to my tv. But the picture was displayed in 4:3, low resolution (looked to be 480i), and was a little "wavy".
    Is the problem that my TV is not compatible with the new apple TV?
    Or i was thinking that maybe i need to get a new HDMI/DVI adapter. the one i have is a few years old. are the newer adapters on the market have new/better technology?
    thanks for anyones help. i really don't want to have to replace my tv or return my new apple tv

    I've been pulling my hair out on this. I have a Sony KV-34XBR800 with a DVI port that supports HDCP. According to the manual the HD suport is 1080i and 720p ..... perhaps also 480p and 480i, but i'm not sure if the latter two are supported on the DVI port. I've tried two types of cables/adapters with the ATV2 and just get a black blank screen. No picture, no apple logo ... nothing.
    The audio and Airplay work great using the optical connector. And when I connect the ATV2 to my daughters newer Bravia the video works great. But on the older Sony .... nothing.
    I can't believe that this is a cable problem, but since that's the only component that I have the power to change out ... that's what i've been doing.
    Any other suggestions? I'd prefer to not go out and have to buy a new TV or tuner to get a $99 box working !!!!
