L530 displayport - no output

We've recently purchased around 25 L530 laptops, most of which work without any problems. A couple however have an issue. The built-in displayport will not output to a 2nd monitor, or to a projector. All of the laptops have bee imaged the same, with the latest HD 4000 drivers installed, so I don't think it's a driver issue.
The 2nd display is detected by the laptop in the graphics properties/windows display settings, but it fails to replicate/extend the image. I was wondering whether anyone else had this issue, before I consider returning them.
Cheers
Jason

Look at other similar threads (e.e., http://discussions.apple.com/message.jspa?messageID=3536313#3536313). I had the same proble, and it was due to a loose cable from the audio card to the board, possibly due to a memory upgrade done in the shop (the cable is at risk). I solved it by opening the mini and just moving a little bit the cable.

  • [SOLVED] Only HDMI/Displayport audio outputs; no sound from speakers

    I have a Dell XPS14 running Arch, which has worked fine for a while, but now has suddenly stopped detecting the internal speakers and headphones, so it will not play sound.   I have tried a few things to narrow down the problem, but I've had no luck so far.  In GNOME shell, when I press the physical volume up/down buttons on my laptop, it displays a sound icon with "HDMI / DisplayPort" underneath . When I go into the gnome shell audio settings menu, everything is greyed out, and no output devices are listed. 
    If anyone has any suggestions as to what the problem might be or how I might go about troubleshooting it from here, I would appreciate it.
    One thing that struck me was that I had installed a music player, Clementine, recently, and I'm not sure if I did or did not ever have sound after that. I installed Clementine and two optional gstreamer0.10 plugins (bad and ugly). Since this seemed like it would be possibly related, I've since removed Clementine, the new gstreamer plugins, and all of their dependencies not needed by any other package. So I now don't think that is likely to be the problem. Just to be thorough, though, here are the packages which were installed:

    Thanks again for the info and suggestions.  I thought the same thing regarding the sparse output of alsamixer, but since I never had trouble with the sound before, I don't know how much would have shown up when everything was working well. 
    I still haven't really found a smoking gun here, unfortunately.  As far as I can tell, the power saving settings look about right, because the power saving settings for the HDMI audio (which works) looks to be the same as the others.
    Thanks for the link with more information regarding the module options for the intel sound driver.  I'm going to dig into those when I have time next week.  The thing that makes me less optimistic that I'm going to fix it with module options is that I can't figure out how those module options would suddenly change.
    I'm also going to try out the linux-lts kernel to see if it behaves any differently, and then maybe boot another distro with a usb key to see if it works, and if so, what looks different.
    Here's what I get from the suggested tests. Let me know if anyone sees something strange that I missed.

  • Tecra S11 mini Dsiplayport - sound output

    Hi,
    I have read the user manual and I did not see anything about mini Displayport sound output.
    Is Tecra S11 supports sound output via mini displayport?
    Are there any mini displayport to HDMI cable which supports sound to send video and AUDIO to my LCD TV?
    Thank You

    Hey thank you for this info. In the past this port was used for Video signal only.
    After your info about working sound Ive found info that audio support was added in 2009.
    This added feature allows now connecting notebooks to modern HD TVs using mini display ports to HDMI cable. It is really nice that there is full video and audio functionality.
    It is really interesting that just several Toshiba notebooks are offered with this port.

  • [W520] DisplayPor​t to dual outputs for 3 external monitors

    I just discovered DisplayPort dual output adapters.  Example:
    DisplayPort to dual DisplayPort, Lenovo brand.
    DisplayPort to dual HDMI (currently out of stock).
    Currently I'm using my laptop display plus two external monitors with one using VGA and the other using DisplayPort for three displays total.  Could I use one of these dual adapters to use three external monitors (plus laptop display) for four total displays?  All displays would be 1920x1080 or less.
    W520 i7-2720QM | 32 GB RAM 1333 MHz | FHD 1920x1080 | Quadro 1000M | Windows 7 & Ubuntu 14.04
    Crucial M500 480GB mSATA + 2 x 1 TB Hitachi Travelstar 7200 rpm | BIOS 1.38

    Hi, just wanted to bump this thread because I have the same question (hope that's okay).
    I currently have:
    W520 screen
    External 1080p monitor
    External 1080p monitor
    I'm hoping to keep those three displays but add a 1080p TV screen via an HDMI out. I would use the dual Displayport adapter noted above and a displayport-HDMi adapter I already have for the TV out.
    If it is possible, would I be looking at a duplicate screen situation, or could I potentially extend my desktop past the three screens for totally new real estate?
    Thanks all!

  • Outputting audio from Mac

    What is the difference between using the Mini Displayport to Output audio (such as multi-channel audio) vs. using the optical out (headphone jack) via a TOSlink/Digital Optical cable to an external sound system?

    MIDI is NOT audio, you cannot transport audio over MIDI cables.
    So, does the Yamaha have audio inputs?

  • X230 UltraBase 3 has no video on Displayport monitor after sleep

    I am having a strange issue with my X230 when docked in the UltraBase 3.  This seems to have started in the last month  so I suspect either recent BIOS or driver issue.
    Displayport video output sometimes fails to go to my external montior (Samsung S22A460 via Displayport to DVI adapter)
    If I turn on the X230 and immediately log on, the external monitor works great.  But if I turn on the machine, walk away for a few minutes and then come back to actually Ctrl-Alt-Del and log on, the external monitor gets no signals.
    I can log on to the X230 and it works fine with its own display.  Undocking and re-docking does not start the external monitor.  Restarting the X230 in the dock does not fix it.  Full shut down  followed by power up will get the X230 to detect the external monitor again.
    If the machine + monitor combo starts and works it keeps working.  The machine can go to power save mode and dim or turn off the monitors.  Both the internal and external will come back on after waking the machine.
    If the external monitor fails to get output at first startup, the only way to get it working is full shutdown and power up.

    If you just bought your mini, it's most likely an Intel-based one. There is no PMU on the Intel mini's and following the instructions to reset the PMU may cause harm. Instead this version of the mini uses a Systems Management Unit (SMU). The proper reset of the SMU can be found here: http://docs.info.apple.com/article.html?artnum=303446
    However, I don't think resetting the SMU will help much here. Is it possible for you to substitute another monitor? If so, and it works, we would want to concentrate on the video settings for your Samsung.
    Your mini is capable of supporting the following maximum resolutions:
    - DVI video output to support digital resolutions up to 1920 by 1200 pixels; supports coherent digital displays up to 154MHz; supports noncoherent digital displays up to 135MHz
    - VGA video output to support analog resolutions up to 1920 by 1080 pixels.
    For DVI your mini should easily support the max. resolution of the Samsung (1600 x 1200). Not so for Analog.
    Also make sure you have the proper DVI cable. You can use either a DVI-D or DVI-I cable. Single link will support resolutions up to 1920 x 1080, while dual-link will support resolutions up to 2048 x 1536.

  • Should mini displayPort work with stock kernel & nouveau?

    Hi,
    I've just set up Arch on a MacBook 5,1 (nvidia GeForce 9400M & mini displayPort graphics output).
    X11 works fine out of the box (stock kernel & xf86-video-nouveau). However, if I connect a external screen with a mini displayPort -> VGA adapter, the external screen only shows some vertical lines. I see the following error:
    [drm] nouveau 0000:03:00.0: auxch DEFER too many times, bailing
    Apparently, such a setup should work with the latest kernel (nouveau driver) and xf86 nouveau driver. In fact, some folks at RedHat report so with my very same hardware setup: https://bugzilla.redhat.com/show_bug.cgi?id=642728
    Anyone has sucessfully setup a external monitor with Nouveau & mini displayPort?
    Any help would be much appreciated, as this feature is critical for me.
    For the record I'm using this from the core / extra repos:
    - Kernel 3.1.5-1
    - xf86-video-nouveau 0.0.16_git20110829-1

    You're right, but I forgot to mention that the Samsung display is just an LCD monitor, so I don´t really need to get audio output for both connections
    Currently, I use an HDMI-to-DVI adapter to connect the Samsung monitor, but I'd like to use the HDMI output to connect my LCD TV instead (and probably a home theater system in the future), and use the Mini DisplayPort output for the monitor, so that I can have a dual-display setup.
    I asked this question, because I read the description for the Mini DisplayPort-to-DVI adapter in the Mexico Apple Store web page, and that description tells that only Macbooks support the adapter. In the US Apple Store page, it does tell that the adapter is supported by any Apple computer with a Mini DP connection, so I just wanted to confirm which description is true, to avoid confusions.
    Anyway, I appreciate that you took the time to respond... Regards!!

  • 120Hz output on MSI Notebooks

    If you haven’t been living under a rock lately, you’ve noticed that not only is higher resolution monitors in extreme demand, but also 120Hz ones. As you might know, in case your panel has a refresh rate of 60Hz (which is standard for PC monitors), you will not notice any difference in framerate above 60 FPS. This is because 1Hz = 1 oscillation per second, meaning a 60Hz panel refreshes 60 times per second, and subsequently a 120Hz panel does this twice as often. Even screens with refresh rates as high as 240Hz exist.
    Slightly exaggerated picture courtesy of Eizo
    All notebook screen panels are unfortunately 60Hz panels, effectively capping what you see at 60 FPS (even if your measured framerate actually might be higher), and if your (non-MSI) notebook comes with NVIDIA Optimus (a technology that automatically switches between the CPU graphics and the dedicated NVIDIA one), you’re even capped at 60Hz on any external monitors connected to your notebook. This is why MSI has chosen to not use Optimus, because we believe that with our high-performance hardware, you should be given the choice to run at higher frequencies, such as 120Hz.
    All MSI Gaming notebooks equipped with DisplayPort supports output of refresh rates higher than 60Hz, in case you’re a 120Hz-connaisseur and worried about maybe not being able to use it on your MSI Notebook.

    All MSI Gaming notebooks equipped with DisplayPort supports output of refresh rates higher than 60Hz, in case you’re a 120Hz-connaisseur and worried about maybe not being able to use it on your MSI Notebook.
    Does this work even on mini-displayport? or just normal displayport? like if i connect monitor to my asus rog swift 144Hz monitor from DP to mini-DP from my laptop will that then be able to run at 144Hz?

  • Xbox 360 to iMac, lets finish this once and for all!

    Hello Everyone!
    New to the forum here and I joint to get a finalised answer to a question I've heard people bickering about for ages! (hopefully the answer will come from someone who has done it/tryed it, not just someone who is going to create a theory of what would work!)
    So I want to use my iMac as a screen for my Xbox 360, because, well, it would be awesome!
    I have so far heard too many different things, for example, if I have a new 27" iMac (which i do) that its possibly just a single wire, mini DisplayPort to HDMI.
    Another thing i have read said, it can only be a single mini DisplayPort to HDMI as long as i have 8GB of Ram.
    Another has said I need to get a complete video converter to run through my mini DisplayPort that would cost around 150 pounds.
    I'm a student and cant really afford to be wrong other wise I would guinea pig this myself, so what im asking for here is someone to lay the smack down. Which is it, if any?!
    Does anyone even know if it has been successfully done yet!? And if it has, to how much success, does it have high lag? Because the guys at AppleCare Support were pretty sure it has been, but they were not allowed to recommend me anything because there is no official Apple fix for it. . . . Hence the reason why i was directed here. . .
    Thanks in advance!

    The answer is behind Door #3. It is a very expensive proposition.
    The two way mini-DisplayPort on the 27" iMac will only accept DisplayPort signaling. So you need a device that has DisplayPort video output, such as a new MacBook Pro which can be attached to the iMac with a simple m-DP to m-DP cable. If you have a device with a DisplayPort video port you can attach it to the iMac with a DisplayPort to m-DP cable. But if the device has any other video output, then you need a video converter to convert the signal to DisplayPort. And most of these converters can only supply 720p to the iMac. One very expensive one can do 1080p.
    You can get the converters from Kanex and Atlona.

  • What kind of display can I add to my MacBook Pro 13 mid 2010?

    I have a MacBook Pro 13 mid 2010.    Please see the specs below.  It is still working great, but I would like to add an external display so I have a bigger screen to work from when I remote into my office desktop.   What would be an economical way of adding a secondary display to use with this machine?  I don't need state of the art graphics.  This is mainly for writing code and documentation.  Thanks.
    Graphics and video support
    NVIDIA GeForce 320M graphics processor with 256MB of DDR3 SDRAM shared with main memory3
    Extended desktop and video mirroring: Simultaneously supports full native resolution on the built-in display and up to 2560 by 1600 pixels on an external display, both at millions of colors
    iSight camera
    Mini DisplayPort
    Video output options
    DVI output using Mini DisplayPort to DVI Adapter
    VGA output using Mini DisplayPort to VGA Adapter
    Dual-link DVI output using Mini DisplayPort to Dual-Link DVI Adapter supports 30-inch Apple Cinema HD Display (optional)
    HDMI output using a third-party Mini DisplayPort to HDMI adapter

    Thanks...just got a Dell monitor and an adapter for the mini displayport to HDMI.  It hooked up very easily and looks great. <$300.

  • For those considering the new MBA, a short review.

    I've had my new MBA (1.86GHz, 128 GB SSD) for two days, and I'm delighted with it. I thought, therefore, that it might be useful to post my experience with the machine for anyone considering buying one.
    The first thing I noticed was how incredibly fast the MBA is. I've got a first gen Intel MBP and a Santa Rosa MB, but the MBA simply destroys them in boot time/app loading time/web page load time, you name it. I'm sure the CPU accounts for some of this, but most of the credit has to go to the solid state disk. It's definitely worth the extra money for such a noticeable speed boost. Nothing lags and nothing drags; the whole system is impressively responsive.
    It's also eerily silent. There's no disk whirring, of course, but also very little sound from the fan. I know overheating and all manner of CPU-throttling, video-stuttering nastiness affected the old MBA, but none of that has manifested itself on my machine. I spent a couple of hours testing it out with flash movies, YouTube videos, a DVD (via SuperDrive), and a bit of gaming (Spore runs fine, by the way), but nothing got hotter than 60 degrees C. I'd say Apple have definitely fixed the heating problems.
    The result is a fast, quiet, stylish machine that gives many full-sized laptops a run for their money. The first generation MBA was labeled a "secondary laptop" by some reviewers, a machine intended for those who already had an MBP or Mac Pro at home, but who wanted something a bit more portable. Version 2 is, on the other hand, an excellent primary lapop for those users who don't have the need for high-end, discrete graphics.
    Of course, everything has its downside, and the MBA is no exception. It could use another USB port (to save me having to carry a port replicator), the mini-DisplayPort video output required the purchase of yet another set of converter dongles (grumble grumble), and the trackpad button seems to require a bit too much force to operate (other threads have highlighted this issue so it may be a fault in some machines). When I first booted the MBA, the iSight camera didn't work, but a quick SMU reset fixed that. The glossy screen is fine for me, although I understand the point of view of those on the other side of the debate, so I can see how it could be a negative.
    And that's pretty much it. I bought the MBA to be a "travel companion," very much secondary to my other Macs. After a couple of days, however, I have relegated my MacBook to secondary status, and made the MBA my main Mac. It's a delight to own and use. I highly recommend it.

    Hi,
    I have a problem with lines on mine. They are in the form of faint horizontal lines running across the whole screen. They are very noticeable on a white background, i.e. when typing on a word processor. I have a MacBook and two iMacs in the house, and these don't exhibit the same problems.
    I find that my eyes get fairly tired after an hour or so use with the Air. The text is not as clear as my MacBook. It was quite disappointing as I expected the display to be better than the MacBook.
    It does seem that quite a few people are having the same problem. There are a lot of postings on forums even at this early stage, for example:
    +“I have the new MacBook Air 1.86/128GB SSD, and I too see very faint lines on my display. They are not completely horizontal - rather, they are pitched at about a -5 degree angle from left to right, and appear to be about 1 pixel in width, and 1 pixel apart.”+
    However, I have a case ID with Apple and will try and reset the Air’s System Management Controller when I get home tonight. If that doesn’t work I’m going to send the Air back for replacement. Considering the cost of the Air I do want to get one that is clear of any defects. Apple support has been very good thus far. I’m also wondering is a driver fix for the Nvidia chip set might solve the problem?
    This issue aside it is a fabulous computer. I think Apple have got the spec spot on with the rev2 Air. It’s responsive, runs cool and is a total joy to use.
    Graham.

  • 2010 Mac Mini OS 10.10.1 screen is stretched out

    Hi,
    I have a 2010 Mac Mini that I use at work and I also use a second monitor via an adapter through USB. The setup worked until I installed Yosemite (10.10.1) on Friday.
    When I go to Settings / Displays I don't get all the resolution options I had before (for my main monitor, 20", res. 1680 x 1050) and my secondary monitor isn't recognized at all (as if it wasn't even connected).
    This is my main monitor: http://www.pcworld.com/product/1417007/lg-l203wt-widescreen-lcd-monitor.html
    I've tried resetting the PRAM but that didn't work. I'm a designer and I can't work with my screen stretched out.
    Can anyone let me know if there is a way to fix this???
    Thanks in advance!

    Look for update software for the USB video adopter.
    The 2010 mini has an HDMI video adopter and came with a HDMI to DVI adopter, It also has a mini displayport video output. You can get an adopter to connect HDMI, DVI and VGA,
    Mini DisplayPort with support for up to 2560-by-1600 resolution
    HDMI port with support for up to 1920-by-1200 resolution
    DVI output using HDMI to DVI Adapter (included)
    VGA output using Mini DisplayPort to VGA Adapter (sold separately)
    Support for extended desktop and video mirroring across both ports

  • MiniDP port doesn't play sound via HDMI

    I have connected it from the computer to the HD tv, and the video works. But the sound will not transfer, The sound preferences doesn't show any outputs but the internal speakers, and I checked the MIDI setup Utility, and it also did not show it as an option.

    Hi, guidino. I have a late-2008 unibody MBP like yours, and I don't expect Apple will ever enable our mini-Displayports to output audio signals. But there are adapters that will combine audio and video signals from our machines into a single HDMI cable and resolve the problem you describe in your post. Here are three:
    This one draws 5.1-channel optical digital audio from the headphone port and power from a USB port:

    This one draws 2-channel stereo audio from a USB port:
    http://kanexlive.com/products/item-id-3323.html
    This is similar to the first one linked above, but less expensive:

    I don't know where you are located, but you should be able to find these adapters or similar ones somewhere near you, or at an online vendor who ships to your country.

  • Downgraded to 10.5, Dead MiniDisplayPort

    I recently set up a new 27" iMac (MB952LL/A) for one of our graphics users, and because AppleTalk is still needed for several printers on the network I wiped the hard drive & installed 10.5.x in place of 10.6 it shipped with. I did some research before doing this & found nothing on Apple's site or anywhere else that said there would be an issue with downgrading. Afterward everything worked flawlessly, until I tried connecting a second monitor to the Mini DisplayPort; no output at all.
    At first I thought it was a hardware problem, so contacted the local Mac shop where I bought it. They messed with it for a couple of days and concluded that there was nothing wrong with the hardware, the problem was with the OS downgrade; 10.5 apparently has no drivers for the Radeon HD 4670 video card in the newer iMac, so it won't work.
    I've got to believe that I'm not the first to try something like this, so I'm looking for workarounds that anyone else may have found to get an external display to work on this machine with 10.5. Install 3rd party drivers? The second monitor is primarily used to display an email window -- all color-critical work is done on the main screen -- so color fidelity isn't a huge issue. I just need it to work.
    Thanks!

    hmm ... you didn't see this: _*Don't install a version of Mac OS X earlier than that which came with your Mac*_ ?
    JGG
    Yes, I did see that, but notice it says, +"If you install an earlier (previous) version of the Mac OS X than what was included, your computer may exhibit unexpected behavior..."+ It then goes on to list specific behavior issues that did not manifest themselves when tested. The internal video works wonderfully with 10.5; why would the external video not work?

  • Which ATI GPU cards offer higher color Gamut?

    I have decided to put an DDR5 ATI card in my new Win7-64 build for editing photographs, compositing, etc. As I have used nVidia up to now I am unfamiliar with the ATI lines.
    I have looked at both discussions here and the ATI site, but it isn't clear which cards will best drive my ASUS higher-gamut monitor. I have to build a new system right now. (Willl not overclock a i7-3770 or use two GPU cards linked with Crossfire. No plans for any gaming.) I would also like to keep this part of the build at a couple hundred or less. I saw that FirePro boards range a lot higher than Radeon, which I realize is gaming-oriented.
    I hope to get DVI and Displayport as outputs. I use two 24" monitors, and the older unit can accept only DVI (or VGA, which I would avoid.)
    Any thoughts about the current ATI line for higher gamut?
    Thanks, in advance.
    jonathan7007

    Thank you Chris. You offer a lot of help here. this was a quick response.
    So I should ask the question a different way. Are the FirePro cards' set up, chipsets etc., more helpful to everyday Photoshop work than Radeon cards with the same amount of memory?
    No 3D or video work for me. Just photo editing. Use of layers.
    There are $375 FirePro cards i could stretch to buy... but what do these boards/chipsets offer for the extra scratch? ATI' site is vague quantifying this.
