External monitor losing connection when Windows goes standby

I got an external monitor connected to a MacBook Pro, whenever Windows goes standby the monitor turns off (also goes to standby mode), I can wake up Windows but the monitor remains without connection. I can manually make it work again by going to the NVIDIA screen.
Is there any way to make this work automatically?

Anybody still want this answered?
Thanks!

MacBook Air is getting hot when external monitor is connected - restart solves the problem

I have a two weeks old Mac Book Air 11" (128GB / 4GB / i5). Sometimes when I connect it to my external monitor, the FAN is getting loud and the MacBook becomes very warm on the surface near the "F3 button". The activity monitor says CPU is at 0-1% and there's no process that causes any CPU load (I switched to "show all processes" of course). Nevertheless something makes the Mac becoming hot. A simple restart while the external monitor is connected solves the issue completely, temperature and fan speed are instantly decreasing. Is this a issue related to the graphics driver? For me it seems the behavior is caused by the graphics processor rather than by the i5 CPU as activity monitor does not show any process causing high CPU load.
Known issue?
Thanks!

I was runnig into the same problem. Plugging in to the apple 23" display at work worked well, but when I plugged in my Dell 23" at home the fan started being noisy...
ALTERNATIVE SOLUTION: it seems to me that putting the air to into SLEEP MODE and back solves it as well!!
I will confirm later on.

Use external monitor w/ Macbook running Windows in Boot Camp?

Within the Mac OS, I close the lid to my Macbook and then hit the spacebar to then use an external 20" monitor. When running Windows within Bootcamp, I shut the lid of the Macbook, but cannot get the external monitor to show an image. How can I get my external monitor to work when using Windows XP within Bootcamp, once I shut the lid to the Macbook?

Hi,
As far as I know, while on Windows XP you have to do it "the microsoft" way! To switch displays, just press Fn + F7 until the image shows at the tv.. tell me if it worked (imho this way better than the "close the lid and touch the external mouse" trick)

7510e printer loses internet connectivity when it goes to sleep

I own a 7510e all in one printer, I connected it wireless again after having it connected with a USB
cable, I had to do this because my printer loses internet connectivity when it goes to sleep or if I get a power outage, this has been going on since I purchased it last year. I got a new wireless router/modem combo from my ISP server and hoped that would solve the problem but it has not.
I cannot get any apps except for those that are on the front of my printer which are just for small kids. I am now told that this printer has been discontinued and 7520 has replaced it, I do not wish to spend another $200.00 in less than a year for a printer. It is registered with HP connected and I have a Efax # and HP connected address, I did everything correctly but it seems that each time I set it up wireless it messes up my desktop windows 7 home premium 64 bit, cloud services told me not to use IE 10 but we are ready to download IE11 so I am using IE 10, this time HP support assistant quit working and I could not even uninstall it until I downloaded microsoft fix it and then redownloaded it from HP web site.
If anyone has any ideas I would appreciate it, I am not on a home group yet it always tells me I do not have administrators permission to do a lot of things, I am the only user.

Hi emma22
Here is a document for Getting the Latest Firmware and Product Updates.

I checked and there is no way to turn off the sleep mode on this model.
I included a document for Printer Does Not Maintain Wireless Connection and to try Solution three: Assign a static IP address to the printer. You will need to get your It department most likely to set this up for you if you don't have full admin rights.

MacBook Pro won't stay asleep with external monitor attached. When sleep is selected from the Apple menu the computer will go to sleep only to continually wake up...go back to sleep...wake up...etc. every few seconds.

MacBook Pro won't stay asleep with external monitor attached. When sleep is selected from the Apple menu the computer will go to sleep only to continually wake up...go back to sleep...wake up...etc. every few seconds. This only happens when using the external monitor. Does anyone have any suggestions?

Mine does that too. The worst thing is when it goes to sleep, then wakes up and keeps running while the lid is closed and it is wrapped up in a case. I am afraid when the hot weather comes it is going to burn up. I am hoping Apple fixes it in the software or they may have a melted MBP to replace.
Then when I open the lid it is crashed running at fill tilt, pumping out heat to beat the band. I am forced to hold the button down and reboot.
I wiped my hard disk and reinstalled my OS, but it didn't help. I reversed my OS to 10.5.0 and it solved the DVI problem but still won't sleep. This post will probably be deleted by Apple, they did it a few days ago. I just don't know what to do, and I consider myself a real Apple expert. Just hoping you realize you are not the only one.

Are you running OS X Lion? If so there are unfortunately numerous threads on here discussing exactly the same problem. So far there doesn't seem to be a definitive solution, with everyone hoping that Apple will come up with a permanent fix.
Here's a quick search of these forums alone - depressing reading:

LaCie external hard drive keeps losing connection to Windows 8.1 computer

Hello all,
My LaCie external hard drive (Rugged version) seems like it keeps losing connection to my brand new Windows 8.1 laptop. The laptop is an HP Pavillion 15-p 133cl TouchSmart Notebook which I just got today. Basically, every few minutes, or if I nudge the external
a bit, the computer will seem like it disconnected and reconnected to the external hard drive in a split second and bring it up in the Windows Explorer. This external hard drive doesn't show any problems connecting to any other computer, but it has occurred
with 2/3 ports on this computer so far. I'm a bit worried, because I definitely DO NOT want the files on this external to get corrupted in any way. What should I do? Thanks a bunch.

may I know your external HDD model, to check which USB version to isolate power and cable connection issue
if this is USB 3.0 try to attached at USB 3.0 at your laptop, your laptop has 2 USB 3.0 and 1 for 2.0, for external HDD with USB 2.0 sometimes need more power / more than 1 connection, sometimes the power will loose
but since the trigger it will disconnect if you nudge the HDD, I suggest back up data to your laptop first, try to change with other data or power cable, try also update your laptop chipset
try to check with other device to isolate port issue
may I know if you are using other PC, did your external HDD also will disconnect if you nudge it?
contact your external HDD manufactured to get some suggestion

Can't connect to my wifi network when external monitor is connected

The computer is a very new Retina Macbook Pro. The monitor is an older Alienware/Benq 20" (3:4) LCD. I'm using a DVI to mini-displayport adaptor and plugging into the thunderbolt ports on the Macbook Pro. Router is a Belkin F5D8233 Wireless N router. As soon as I connect the monitor my connection to my wifi network times out and refuses to let me connect (every attempt just results in a "connection timed out" error). However, I was surprised to find that I could connect to my neighbor's network without any issue. Anybody have any idea what the issue could be?

Maybe related to bullet #7 here http://support.apple.com/kb/HT1365.

Strange issue with external monitor, only working when external speakers plugged in (using Thunderbolt to VGA adaptor)

Hey – I am having a very strange issue with my external monitor; where it only works if my external speakers are plugged in and connected.
I am using a late 2011 Macbook pro, running Mavericks 10.9.4, along with an MBox 2 (USB Audio Interface), and two powered speakers (KRK Rokit 5). This setup has had no issues. I have just acquired an external monitor (Benq T2200HD), which I am using with a thunderbolt to VGA adaptor (a cheap Chinese knockoff adaptor).
To start - I plugged the monitor in with the thunderbolt adaptor, and it powers up and works fine. However, there is a nasty buzz coming from the speakers. I did some research and it looks like a simple ground loop issue. I did a bit of troubleshooting, and this is where things get weird.
What I found is - If I unplug the MBox, the monitor loses signal from the computer (displaying ‘No Signal Detected!’). Further, if I keep the MBox plugged in, however unplug both the cables from the MBox to the speakers, the monitor loses signal. It doesn’t matter if the speakers are turned off, however they need to be plugged in (or the monitor loses signal). Weirder still, I can unplug the MBox, however the monitor will work if I plug in the speakers through my macs headphone jack.
Simply put, the monitor only works if there is a direct connection between the computer, the speakers, and the power source. What is going on here? Is the monitor grounding through the computer port, to the speakers (I don’t know how this works, is this possible?). Could it somehow be the cheap VGA adaptor I am using?
Some other information:
- Everything is plugged into the same multi-box for power. I have tried plugging things into separate sources, and the result is the same.
- If I unplug the thunderbolt adaptor, then the speaker noise disappears straight away.
- The ground noise doesn’t appear in my headphones, which are plugged into the MBox.
Any information would be great – am I missing something here, or is this genuinely weird?

Well, I went back into Best Buy to test on 3 other laptops (2 Asus, and their floor model for this Sony). It seems to be doing the same problem so at least I was able to rule out broken hardware issue on my particular laptop.
Here's what I did to test:
Since I couldn't really install Adobe Premiere on their machines, I used the DVIO software (http://www.carr-engineering.com/dvio.htm) and a 5 min clip I captured. I transferred onto their machines, hooked up my Sony D8, and attempted to play the video. It would play for 15 seconds and then stop and jitter with a loud noise (like it does on my laptop). I even tried changing each machine's firewire driver to the legacy one and same results. I pulled a brand new 4 pin to 4 pin firewire cable off their shelf and still the same problem.
I think I've nailed it down to Win7x64 bit Home Edition not playing nice with Firewire driver. Very annoying. I can't find any concrete evidence of this from other users on any of the forums that have my particular problem, but from my own testing, it's all I can conclude.
I have 2 other things I can try:
1. Opening the laptop and looking at the firewire to maybe find appropriate driver (ugh, I don't want to have to open this thing up).
2. Upgrading to Win7x64bit Pro and possibly testing with XP on the new MS Virtual PC (http://www.microsoft.com/windows/virtual-pc/). I can't do it with my Home edition apparantly.
Who needs to view video on an external TV anyways....sheeesh...(scarcasm).

Hello cgoldberg11
Please go to the below link to test if you are having a speaker hardware failure.

This will rule out hardware failure, let me know how that goes.

W520 external monitor not connecting properly

W520, Windows 7 (64 bit), NVIDIA Quadro 1000M 2GB DDR3, purchased November 2011. External monitor: HP 2511x.
Haven't been able to find this issue in a previous thread.
In Optimus (preferred) mode, when I plug an external monitor VGA, HDMI or DVI (via displayport) cable into the laptop or mini dock, the laptop LCD goes completely dark (black). This happens whether the external monitor is turned on or off, for the VGA and HDMI plugs. If the external monitor is turned off when the displayport plug is inserted, nothing happens: the laptop screen stays on, but when the external monitor is turned on, with the displayport plug in use, the laptop LCD goes dark.When the plugs are removed, the laptop LCD comes back on, except when the displayport plug is removed (then, the laptop screen stays dark).
In all cases, the external monitor is not recognized by the laptop, and if turned on at the time (the external monitor), shows a message which reads that it is going to sleep.
Device Manager shows the Intel and NVIVIA display adapters and does not show the external monitor (because I cannot hook it up without darkening the laptop screen).
A few months ago I had the Optimus arrangement working, using the NVIDIA control panel to set up a clone mode. The external monitor worked beautifully. Then I disconnected from the external monitor for several weeks, and now it will not work.
The external monitor was used until very recently on a separate PC, which I no longer have, and the external monitor driver was reloaded this morning.
I welcome sugestions on how to plug into the laptop without causing the laptop screen to go dark, which I think would then allow me to set up the external monitor as desired.
Thanks,
RR

But did you RUN the nVidia driver file that you downloaded??? It is an EXE, and you must RUN it after downloading.
The fact that your Device Manager -> Display Adapters still shows "Video Controller(VGA compatible)" specifically tells us that you have NOT YET INSTALLED THE CORRECT DRIVER FOR YOUR VIDEO CARD!!! You are still running with the vanilla generic Microsoft VGA drivers which will work generically and support only minimal capability for EVERY SINGLE VIDEO CARD MANUFACTURED. It doesn't support all of the capabilities of the K1000M.
YOU MUST ACTUALLY RUN THE DOWNLOADED DRIVER INSTALLATION FILE EXE, in order to perform the process of actually installing the driver for your "Video Controller(VGA compatible)" device, which of course is really the K1000M.
Once that driver is correctly installed, it will now appear as "NVIDIA QUADRO K1000M", instead of "Video Controller(VGA compatible)" as you currently show.
The reason your desktop icons are currently very big, and that everything else is currently very big/enormous, is because your desktop resolution is not set correctly... although it may be set as high as it can go for the moment. Only when you finally install the true nVidia driver will your default resolution be presented at what the hardware monitor "recommended" resolution should be, which is likely at least 1920x1080 if not 1920x1200. Then everything will appear "normal size", and at the very least will not appear to be ENORMOUS as you currently see.
Also, I'm expecting that once you get the correct nVidia driver installed for the K1000M that your external monitor will now work perfectly, and will not black out.
So... even while you're still using the current vanilla generic MS VGA driver (although again, your mission is to install the nvidia driver for your K1000M), just right-click on the desktop and select "screen resolution" from the popup menu, to get the "screen resolution" dialog window.
Then click in the "screen resolution" dropdown list to get a dropdown (with a slider) offering you to change resolutions. Pull the slider up to whatever you want and click, and then push the OK button. You'll then be offered a confirmation dialog window allowing you to click OK or CANCEL within 15 seconds to accept the resoluton change. Click OK to keep what you just set.
Your desktop icons and everything else will now appear smaller (or at least "normal"). Temporarily, you've got things satisfactory at least.
But you'll do the same thing again AFTER INSTALLING THE NVIDIA DRIVERS. This time the dropdown "screen resolution" list will have a slider whose top value will show "recommended", and will probably be 1920x1080 or 1920x1200. Pull the slider all the way up to that value and click. Then again, push OK, and OK to the confirmation.
Again, your absolute test goal is to see "NVIDIA QUADRO K1000M" in Device Manager. You should NOT BE SEEING "VIDEO CONTROLLER (VGA COMPATIBLE)".
The installation of the nVidia driver will also get you "nVidia Control Panel", where you can then perform additional customizations, such as whether or not you want to use BOTH the laptop screen as well as external monitor configured in either "laptop screen only", or "clone mode" (i.e. duplicate of single desktop on both screens), or "extended mode" (i.e. double-wide desktop extending across both screens), or "external monitor only," (with laptop screen dark).
Again... YOU MUST RUN THAT DOWNLOADED NVIDIA DRIVER INSTALLATION FILE EXE. It doesn't run itself, unless that's what you have set in your browser when offered the choice of RUN or SAVE. But if you SAVE it, then you must yourself manually run it after the download completes.
IT MUST BE RUN TO INSTALL THE DRIVER. Then you'll see "NVIDIA QUADRO K1000M" in device manager. Until and unless you see that value, if you still see "VIDEO CONTROLLER (VGA COMPATIBLE)" then you have NOT YET DONE WHAT YOU NEED TO DO.
Understood?

Tecra A9 - external Monitor shows stripes when using the Laptop pluged.

Hello
I've heard about at least 3 Tecras A9 witch produces stripes on the external Monitor only when the Laptop is pluged. When using the Laptop with the battery, the Monitor works just fine. they tried to divide the cables of the Monitor and the power supply as far as possible, but still the same problem. When using the Laptop with a non-toshiba-AC Adaptor, the external Monitor is working fine.

Hello
In my opinion you should visit nearest authorized Toshiba service provider. They can connect your Tecra to external monitors and test it. If the result is the same I am pretty sure you will get AC adapter replacement for free.
Do not wait and discuss for days here. Contact them and I hope they will help you.

External Monitor with iTunes - iMac screen goes black

I have an iMac with iTunes 7.7/Leopard and an external VGA monitor (I use the standard Apple mini-DVI to VGA converter) then I use the external monitor to watch video from my iTunes library.
All works well - I have my desktop spread over both monitors, I fire up a movie from iTunes, move the video window across to the external monitor and everything is good - I can watch the video on the external monitor whilst continuing to work on my Mac - the iMac screen displays the Mac desktop as normal.
However, if I put the movie into fullscreen mode (view -> fullscreen on the iTunes menu), the external monitor displays the movie in fullscreen mode as it should, however the iMac monitor goes black.
The only way to fix this is to exit fullscreen mode and go back to one of the view options (rg fit to screen).
Any ideas how I can have my external monitor in fullscreen mode and have my desktop back?
Many thanks
SM
