External Monitor not working with U430P

I have a U430P laptop and a Dell U2412M external monitor.  Both have worked great together until yesterday, all of a sudden my external monitor won't work, the screen is black and my laptop doesn't recognize the device.  I have tested the monitor on another laptop and it works fine.  I have tested my cord on another system and it too works fine.  What is wrong with my U430P?  This laptop is only 5 months old!  Thank you.

  • External Monitor Not Working With Macbook Pro

    My computer was working fine with an external monitor, then my computer froze, and I had to hold down the power button. When I turned it back on, my computer would not work with an external monitor. I've tried different cables, so it's not the cable. The monitor is being detected by the computer, but nothing is showen on the external monitor. When connecting the monitor to the computer, the computer's screen goes blue, then turns back to normal.

    I cannot reset the SMC by removing the battery, I do not have the confidence to remove my battery, and do not have the time to send the computer to someone else to do it.
    I also tried updating my OS from 10.7.4 (Might've been 10.7.3) to 10.7.5.
    My computer is a MacBook Pro (13-inch, Mid 2010), running OS X 10.7.5 Lion.
    I need to get this problem fixed ASAP, any help is appreciated.
    Kind Regards,

    I forgot to mention, I'm connecting the monitor via MiniDisplay -> HDMI. I've also tried USB -> HDMI and USB -> DVI -> HDMI but none of them seem to work.

  • External Monitor Not Working after 10.9.3

    I have two Macs which are not working with an external monitor anymore through the thunerbolt port. I have tried different types of connections (HDMI and DVI) and two different external monitors in an attempt to determine the issue. The only common denominator to the issue is the update to 10.9.3 OS X. I have also reset PRAM and changed between mirroring and non mirroring to no avail.
    Mac #1:
    MacBook Pro8,1
    Intel Core i5
    2.4ghz
    Intel HD Graphics 3000 512MG
    External Monitor: Resolution 1920X1080 @60hz
    32 Bit Color (ARGB8888)
    Main Display: Yes
    Mirror: Off
    Online: Yes
    Rotatino: Supported
    Mac#2:
    MacBookAir6,2
    Intel Core i5
    1.3ghz
    Intel HD Graphics 5000
    External Monitor: No information as it's not connected at this time.

    Well low and behold I tried clearing PRAM again and I reset my monitor to factory defaults. Reconnected my monitor and the thing works now. Very strange but I'm Happy that it's working again. *WHEW*

  • Why does Server Monitor not work with non-Xserves?

    Does anyone know why Server Monitor does not work with non-Xserve computers? We acquired a Power Mac for a server, based on there being no apparent difference except for the obvious. Turns out there are some differences after all.
    Do Power Macs lack some hardware components or is this just a software thing?

    God question, unfortunitly I dont have the answer but I would also like to know why the software only works for X-Serve....Is there any 3rd Party Software that is similar to "Server Monitor"?
    Thanks

  • External monitor not working - software upgrade

    Use an external LG monitor with my Macbook at work - has worked like a charm. There was an Apple software upgrade this weekend - today, when I came back to work, I can't get my external monitor to work. The Mac doesn't see that it's there and the monitor's stuck in Power Save Mode.
    Thoughts?

    I have reset the PRAM and confirmed that the monitor and cable are functioning properly, but still no change.

  • External isight not working with Macbook Pro early 2008

    My external isight is not working with my Macbook Pro early 2008 (2.4 GHz, Intel Core 2 Duo, 6 GB RAM, OSX Lion). It goes warm when plugged into the firewire port but is not recognized in system prefs (lists as "unknown device" and also does not turn on (green light. I tried resetting PRAM and all the other stuff as suggested here but no luck. It used to work fine on a 1st generation Macbook and I remember that one of the first times I tried it with this machine here it turned on for a few secs (green light) but then it just simply stopped.
    Unfortunately, I have no other firewire device to check the port.
    Any ideas, dear community?

    Our (old) external Firewire iSights can be sensitive to dust, shock, vibration, humidity, and other environmental factors in storage.  (I store my spare in its original plastic shipping case with a new desiccant pack on a solid shelf - never in a desk drawer or other container that moves.) 
    You have tried several good things and may be finding that your old iSight needs work. 
    Here are the alternatives I can offer.  Consider any you have not tried in any order you like:
    (1) You can try Apple's suggestions from http://support.apple.com/kb/HT2090
    Test in more than one user account and with more than one Apple softwre application.

  • External equalizers not working with Spotify

    I'm using Spotify on a 2nd gen Motorola Moto LTE, Android version 5.0.2. I'm trying to get an external equalizer to work with Spotify, as the bundled one is close to worthless (as it doesn't allow setting the levels of the bands, just choosing between 4 presets). So far I haven't found a working solution. Most eq's don't affect sound at all. The most promising failure so far has been an app called "Equalizer" from "Smart Android apps llc", which works sometimes, but has a lot of issues (crashing after notification sound has been playing, no sound on phone calls.).
    This is what I've tried so far:
    1. All the top hits on Play when searching for "eq". Many recommend turning of the "Sound effects" service, this has no effect however, even after much rebooting and so on.
    2. Removing and reinstalling Spotify. Resetting phone to factory state and reinstalling Spotify.
    3. Disabling 'nuplayer' in developer settings looked promising, but unfortunately it is already disabled.
    If you have any other suggestions, I'll be happy to try them.

  • External DVI monitor not working with new iMac 27"

    I recently purchases a 27" iMac and i'm trying to get it working with a 3rd party DVI external monitor. I got the Apple mini display port (thunderbolt) to DVI adapter and connected everything via a new DVI-D cable. The iMac detects there is a monitor and even shows the display as it should.. however, the monitor has a large amount of static/snow/noise (red coloured), so much so that the monitor is unusable. There is also a considerable amount of flickering.
    The monitor works fine when connected to a Mac Mini with the Mini DVI - DVI adapter, (old set up) so I know the monitor's connection is not faulty.
    Also, the monitor connects fine to the iMac when using a mini display - VGA adapter. The problem really seems to be with the combonation of DVI cable and adapter.
    Has anyone had any experiences with DVI monitors connected to new iMacs via the thunderbolt port?
    (System: iMac 27" 2011, 3.4GHz i7, 16GB RAM, Graphics AMD Radeon HD 6970M 2GB. All system updates installed, running OSX 10.7.2)

    I think that your assessment is right, the ATI must be on for DVI to work (so far I've only tested with an older T61p and the Quadro graphics are always running).  Can't you set the machine so that when docked the ATI is used, but on battery the internal video is used? That would be what I would try.

  • External Display not working with MacBook Pro 13" (early 2011)

    I just bought the current MacBook Pro 13" (i7 processor). My external display (Benq 20"W, 1600x1050) always says "No Signal Detected!". I've tried it with a DVI-Adapter (Griffin Video Display Converter) and with a VGA-Adapter (LMP Mini DisplayPort-VGA-Adapter). With lower resolution I once got a picture (but with weird lines). On my old MacBook (white, 2.16 Ghz) there was never a problem with this display (also OS X 10.6.6). Who can help?

    Check this post if you want more info:
    http://discussions.apple.com/thread.jspa?threadID=2774718
    The gist is that DVI is currently very iffy through Thunderbolt. Mini display -> mini display OR mini display -> HDMI should work fine. It's most likely not your adapter itself but the fact that it's DVI.
    If you can, get a mini display -> HDMI adapter and try that (assuming your external has HDMI).
    I should hear back tomorrow or Monday from apple engineers with more specific info about this issue and I will update then.
    BTW- DVI anywhere in the chain will make things fail. Mini Display -> DVI and a DVI/HDMI cable won't work with any reliability (I've tested it on three completely different monitors).

  • External monitor not working after ML upgrade

    I have a late 2008 Unibody Macbook and normally use it in clamshell mode with a Samsung 2043NW monitor if I'm in the office. Previously working fine in 10.5.8 through mini display port adapter. Upgraded via fresh install of 10.6.8 to ML, and the monitor flickered on occasionally but otherwise would not work - when it did display it showed the same resolution as the macbook screen i.e. 1280 X 800 instead of 1680 X 1050.
    There's a thread here related to this: https://discussions.apple.com/thread/2387462?start=15&tstart=0  but this software was not the answer. I can now view the screen, but it is still being sent a resolution of 1280X800, rather than 1680X1050 (i.e. a fuzzy mess). It also will not work in clamshell mode at all, and just goes to sleep when the case is shut.
    Anyone have a solution for this, or have I been 'obsolesced'? Does anyone have a unibody Macbook that DOES work with an external monitor?

    OK, now here's an interesting thing - the macbook has begun to work in clamshell mode. This is REALLY weird. Tried again this morning in the hope of getting back the monitor control icon in the toolbar and it booted straight into clamshell mode with the lid shut.
    When I first had this running 10.5 it would only work in clamshell mode if you pressed the power button and immediately closed the lid before the screen lit up grey. More recently it has been perfectly happy to enter clamshell mode after a period of use normally, just plugging in the monitor and shutting the lid. It would be nice if this behaviour were to start again soon.

  • Ultra dock + three external monitors not working

    Hardware:
    W540 + Ultra Dock (170W)
    2x 24" LCDs @ 1920X1200 (DVI only)
    1x 30" LCD @ 2560x1600 (DVI only)
    1x Display Port to DVI Active Converter (for the 30" LCD)
    What I want to have is four displays: W540 LCD + 3 external monitors as described above. However, I can only get two of the external displays to turn on regardless of how many chickens I sacrifice. Note: I've searched extensively to see if others have had this problem, which they obviously have, but none of the solutions worked. 
    I think the issue is the 'advanced' mode, but I already turned it on in the BIOS. The laptop LCD works correctly (2880x1620), the 30" LCD works correctly with the display port to DVI active adapter (2560x1600), and one of the 24" LCDs works correctly (1920x1200). However, the other 24" LCD isn't available in Windows as a detected display unless I start swapping cables, which will then enable it while disabling the other 24" LCD.
    For reference, the connections are as follows:
    Laptop LCD (built-in)
    30" LCD: DisplayPort to DVI (active); Ultra Dock DisplayPort 0
    24" LCD number 1: DisplayPort to DVI cable (passive); Ultra Dock DisplayPort 1
    24" LCD number 2: DVI to DVI; Ultra Dock DVI Port 0
    It's my understanding that the K1100M discrete graphics card should be driving all three of the external displays, but that isn't the case right now. I see one 24" and the 30" displays in the Nvidia Control Panel and I see all three working monitors (including the laptop LCD) in botht he Nvidia Control Panel and the Windows Display area.
    Things I've tried:
    Uninstalled + reinstalled Nvidia Quadro drivers
    Uninstalled + reinstalled Intel 4600 drivers
    Enabled Advanced mode in BIOS
    Restarted 5,000 times
    Swapped cables until my fingers started to bleed
    Updated the firmware of the Ultra Dock (it was already fully updated)
    According to this page, I should be able to connect six displays including the built-in LCD. When I first looked at it, I thought I could use both Ultra Dock DisplayPort ports as well as the Ultra Dock DVI port, but it's very unclear if that's actually the case. What does it mean by DP or HDMI and DP or DVI? Does that mean I can use both DisplayPorts (which I'm currently doing and it works) only? Does it mean I can use both DisplayPorts as well as HDMI and DVI? Does it mean if I want to use HDMI and DVI that I can't use either DisplayPort? Does it mean DVI and HDMI both share an output with one of the DisplayPorts so only one of each can be used at a time? TERRIBLE DOCUMENTATION.
    Any help would be greatly appreciated as this has been extremely frustrating. I have a feeing the solution is going to be a disappointment as well because it's probably going to involve buying yet another adapter and/or using the Mini-DP output on the laptop instead of, you know, actually being able to use the expensive Ultra Dock...
    [rant]
    I have no idea how to tell if everything is working because the graphics card situation is extremely confusing. I didn't realize when I bought the laptop that the discrete card couldn't drive the laptop's built-in LCD, which is very annoying. Or, maybe that's not true, but the documentation is so confusing that I can't be sure either way. Also, and this really pissed me off, the Ultra Dock DVI connector can't drive a dual link display. What the hell??? Why was this not clearly annotated somewhere? I really hated needing to purchase a DisplayPort to DVI active adapter to make my brand new laptop dock work as advertised. UGH.
    [/rant]

    I'm struggling with a very similar problem. (Thinkpad W540, K2100, Ultradock 170W)
    I am using 2 external monitors right now in bios display standard mode - it's the only way they work at all for me right now. I have tried uninstalling graphics drivers, enabling advanced mode, and restarting, but none of the external displays are detected. I've also tried updating the dock's firmware, but it doesn't seem to be updating (this may have already been updated).
    Current working setup:
    - 2 x 22" external LCDs connected to Ultradock via DP -> DVI cables
    - Laptop integrated LCD
    Related but not quite as equally frustrating, the integrated LCD does not resume when waking the computer from a sleep state. Only a reboot brings the display back.
    I'd like to connect another 24" display over HDMI, but don't have any confidence of it working since advanced mode is utterly worthless for me at the moment. I'm quite dissatisfied especially since I purchased an extended warranty and last time I called for support Lenovo tried to sell me an additional support plan claiming that software was not covered under my current warranty.

  • IMac external monitor not working after lion upgrade

    Hi,
    I have had an external monitor hooked up to my 09' imac for over a year now. I upgraded to Lion and ever since then it hasnt worked but one other random time when I moved and hooked everything back up. Im very tech savy, but this just doesnt make sense. Have combed google to find a solution. I have a Samsung 22in moniter and all the blue power button does is blinks at me. I am using a miniDisplay to DVI connection.
    Does anyone have any suggestions other than resetting the ram?

    I guess it's possible you've got some kind of hardware problem.... but not likley given it started with you installed your OS.
    Here's a few things to try:
    1. see if you can borrow another monitor just to be sure your monitor isn't the problem.
    2. in System Prefs, and the Displays pane, click on the Detect Displays, then then the Gather Displays. If you get two diffenet display panes, that would lead me to think it's a monitor problem.
    3. Lastly, disconnect your 2nd display, and restart. Then Shutdown, reconnect it, and see if that helps.
    and of course..
    4. make sure that all of your connections and adaptors are tight.

  • MBP i7 15" - External Monitors not working

    Hi All,
    Ive been using HDTVs over HDMI and Dell Monitors over DVI fine for the last 2 months, but as of a few weeks ago. I cant get any output at all on either connection!
    When I plug in my Miniport adapter, the MBP screen blinks blue (as it usually did, when about to change display settings) but then nothing happens. No external monitor output at all, in any shape or form!
    Similarly, when I plug the HDMI/DVI into the TV, it auto-detects that something has been plugged in and begins trying to auto-detect a signal but to no avail (mean while the macbook screen flicks to blue as described above).
    I refuse to believe that my adapter is knackered, as when plugging and unplugging, both TV and MBP show signs that its trying to connect.
    I've rebooted, and done the SMC reboot, and even uninstalled gfxCardStatus in case that was affecting it, but no Joy.
    I have upgraded to 10.6.5 but I cant be sure when this actually occurred, and as to whether or not this caused the problem.
    Any help would be lovely.
    Kind Regards
    Oli
