VGA Display Issues in Bootcamp 3.2 Windows 7 64 bit

Hi Apple Community,
I am having some issues connecting my brand new MBP (15 inch, 2.3 GHz Core i7, AMD 6750M Early 2011 Model). I have successfully installed Windows 7 64 bit on my computer via Bootcamp and everything was running as expected. I am getting very decent performance for my graphic applications in Windows and am very satisfied with the flexibility of running both Mac OS and Windows on my machine.
However, recently I was tasked to give presentations and bought a mini-display to VGA port as most projectors I use have a VGA input. I was able to use Mac OS to give presentations very easily and it just seems to work. This was working well and great; however, when I needed to show my work on the windows side of things, the display just doesn't work. I have tried with many different projectors but cannot get my computer to display my windows desktop into my projectors via VGA.
Is there something wrong that I am doing? Why does it work without problems on the Mac side but not in Windows? My older computer was able to connect with the projector (Macbook 2006) without problems in Windows. Any help is appreciated. Thank you.

Hiya,
If you look at the end of your VGA cable and count the pins in the end, it will either have 14 or 15 pins. You need one with 15 little pins.
The name of the cable you need is True Display Data Channel (DDC). You can get them from ConnectorCo.
Www.ConnectorCo.uk/catalogue/leads_svga/DDC.htm
However if you have a 14 pin short VGA cable, it does work. My short VGA is 1.5 metres. If I try it with a 10 metre cable with 14 pins it won't work.
I'm assuming a VGA with all 15 pins will work over a 10 metre cable, but I can't test out the theory until I buy one.
I looked an Apple Support last night and if you bought your Mac in the last 30 days you can get free support. I bought mine in April, so I will email them later today.
Hope this helps. If Apple come back to me with an explanation and answer I will let you know.

Display Quality issue after updating to Bootcamp 3.1 (windows 7 64-bit)

I managed to install Windows 7 64-bit without issues (all issues got resolved after installing bootcamp 3.0 from the OSX DVD).
Then I saw the BootCamp update for windows 7 64-bit as being (Recommended) and I installed it...
after that I got a problem in the screen where I get low quality in gradient colors.
I tried installing the ATI Radeon 4850 Driver from the ATI website , but without any luck, the driver is identified correctly and color depth (32-bit) , but still the quality isn't acceptable.
Anyone facing similar issue? please advise ? I tried restore point but it failed.
Any suggestions?

Are you sure? Since both CPU-Z 1.53.1 and Catalyst Control Center are stating that my graphic card is a ATI Radeon HD 4850 (device ID 944A).. :S
So, Bootcamp 3.1 seems to have solved nothing (plugging headphones in still
jumps one core straight to ~100%) and actually created a problem that didn't
exist - i.e colour banding!. And, obviously, no software fix is going address
You could try to roll back the driver. I've more or less the instruction written in this thread and at the moment, with 8.661 version of the driver I don't have the color banding issue (I've to test stability yet, since it seems that this driver version is quite more unstable).
However, yeah I feel your disappointment, I'm a Mac user since 2001, changed several macs and this is the first one that comes with so much issues.

Issues with BootCamp and mounted windows 8 install disk

I've been trying to install Windows 8 from a mounted Windows 8 System Builder install disk. When I mount the ISO and try to use bootcamp to install windows 8 the bootcamp application will not recognize the install disk I have mounted. Any issues? I've also attempted to install the disk on USB with no luck. The reason I need the mounted ISO is because my DVD drive is busted. I created ISO on a friends macbook pro by using disk utility. I have the dmg file, cdr file, and iso file but have had no luck with any of them. Can anyone help? I'd really like not to have to have to buy an external DVD drive.

Google is your friend. Easy? Probably not but it appears doable. Proceed at your own risk.

How to fix applepushservice.dll issues for downloading iTunes on Windows 7 64 bit

I recently had iTunes crash on my home PC, Windows 7 64-bit. I have tried several attempts to uninstall and reinstall the program and it still does not work and I receive error messages. The latest: The program can't start because ApplePushService.dll is missing from your computer. Try reinstalling the program to fix the problem. Problem is, the articles that I have seen state this is an Unknown source and my firewall will not allow it to be installed. The original error was a Windows Error 7 (registry & .dll issues). Any suggestions on how to fix this problem?

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.

Issues with Thinkpad yoga on Windows 7 64-bit

I uninstalled the windows 8.1 that came with my Thinkpad Yoga to installe windows 7 64-bit because there was no support for Power Manager ( a tool that allows you to charge your battery only upto a certain percentage (eg 40%) which helps reduce battery aging when the notebook is mostly operated on AC power).
Doing that required me to fully clean the Hard-disk during the installation process.
I installed almost all of the drivers available on http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-yoga-series-laptops/thinkpad-...
for thinkpad yoga and windows 7 64 bit.
Happily, this provided me the Power manager, and I can use it just as I wanted.
However, all these has brought in additional issues which are listed below:
1. The touch pad right click doesn't work. Only two finger tap works as right click.
2. The touch pad gestures for zoom and scroll doesn't work at all.
3. The screen auto-rotate doesn't work.
4. The touch screen gesture for zoom doesn't work.
I did install the ultra-nav and screen-rotate drivers, but I get error messages regarding synaptics ... not working and also sensor driver not working during the windows startup.
Any help please?
Thank you.

Just when I was happy that major issues have been resolved by constant updating, I am now experiencing this frightening problem. Mostly during startup, and lately in the middle of working, the screen freezes, shows very damaged image (like TV noise), produces the most unpleasant sound through the speakers and nothing works. I need to restart and hope that it will be ok. Sometimes it requires 2 or 3 restarts, going to safe-mode and returning back to get the issue resolved.
This has happened three or 4 times within 24 hrs. I searched in the forum and for another model it was suggested that epresscache might be the cause. I disabled the service, but the problem reappeared even then.
Any help please:
This is what appears on the screen when the computer freezes and produces loud unpleasant noise sound.

Bootcamp 4 and Windows 7 64-bit

I would like to have Windows 7 64-bit installed on my Macbook Pro (17-inch, Early 2011). Since I have Bootcamp 4, I'm not able to install Windows 7 64-bit. Bootcamp 5 makes available the installation of Windows 7 64-bit.
Can I upgrade from Bootcamp 4 to Bootcamp 5 so I could then install Windows 7 64-bit? If so, what must I do to upgrade to Bootcamp 5?

Welcome to Apple Support Communities
Boot Camp 4 also supports the installation of a 64-bit Windows 7 version on your MacBook Pro, so that's not the problem. Another thing is if the latest Boot Camp version for your MacBook is Boot Camp 5.
Follow Apple's steps to install Windows 7 > http://manuals.info.apple.com/MANUALS/1000/MA1583/en_US/boot_camp_install-setup_ 10.7.pdf Instead of downloading the Boot Camp drivers from Boot Camp Assistant, download them from the Apple website and follow its steps > http://support.apple.com/kb/DL1638

[XI 3.1] Issues during "Clean" install on Windows Server (64-bit) OS

Started setting-up a SANDBOX yesterday of BOE-XI (Release 3.1) on a "Clean" Windows Server (64-bit) OS.
I hit a couple of issues that I think may be related to the DEFAULT "Program Files" location on the OS being...
C:\Program Files (x86)\
...rather than...
C:\Program Files\
I chose to install the MySQL database and the IIS and Tomcat DEFAULTs for the CMC and InfoView.
BOE-XI (Release 3.1) said that it ran OK, but we had two issues that we are now cleaning-up...
1.) SIA did not install / appear in CCM. Had to manually create a new one.
2.) Tomcat InfoView and CMC were OK, but the .NET (IIS) InfoView throws a "The page cannot be found" error when trying to connect to...
http://<servername>/InfoViewApp/logon.aspx
Anyone seen this issue before - or have a link to a "Best Practices" document for installing on BOE-XI (Release 3.1) on the Windows Server (64-bit) OS...?
Thanks in Advance!

Hi,
I am also experiencing this issue with Crystal Reports Server XI installed on 64-Bit Windows Server 2003 Enterprise Edition.
I am also getting the following error when trying to view reports

Does anyone know how to resolve this?

Issues installing Acrobat XI with Windows 7 64 bit

Trying to install acrobat reader on a new computer build with Windows 7 64 bit.
The installer file downloads OK and executes OK, but as it start to install I get a blank, small, dark grey window "Adobe Reader Installer" Completely blank except for the border and title, no buttons, no words.
I've tried saving and running the installer with the same results. Tried running Microsoft fixit with the same results.
What next?

The same question is posted multiple times every day, and the answer is always the same: use the offline installer from http://get.adobe.com/reader/enterprise/
B.t.w. the name of the software is Adobe Reader, not Acrobat or Acrobat Reader.

Display Issue in Forms 10g on Windows 7.

Hello,
I have a peculiar problem while working on Forms 10g application on Windows 7 Platform. I am able to build form modules and run them. The problem is in the display in the Oracle Applications Server Forms Services window. I use internet explorer(default) to display the results. Apparently I am able to view the correct output only after I scroll the mouse pointer up and down once. To make it more clear, when I click on run form option of the forms builder, the output opens in an internet explorer window. But the screen is blank. I am able to view the resulting frame and its contents after I move the mouse pointer once, in a vertical direction. My instructor told me that it is a problem specific to Windows 7 and can be rectified by using TuneUp Utility but of no help.
Can anyone solve this please.
Thank you!

Hi,
Since the form is appearing the issue is something to do with the client machine where you are opening the form from.
Try again after clearing the web browser cache and java cache. Also you may try this from another machine and confirm of the situation.
Thanks &
Best Regards,
Asif

X200 VGA Display Issues

Ok so I'll try to be as specific as possible. I have an X200 2024-B27 and I am running windows 8.1.
I just recently attempted to hook up a second monitor to it. Once it is hooked up it works but cuts on and off every 5-10 seconds. Once it cuts off it then cuts back on. Does it totally random, there is no rhyme or reason to it, at least not that I can tell. The issue I have is it worked perfect on my R61 runnin 8.1 as well. It also runs perfect on multiple other laptops.
I have attempted to update the driver but when I download it from here it tells me my system doesn't meet requirements. I also attempted to download the display driver for 8.1 directly from Intel. That also greets me with the same response.
I need this to work for work. Please any help would be greatly appreciated!

Please I need help with this! Has no one had a similar issue?

T410 VGA display issues

I am finding on our T410 systems we are getting in that the VGA output is so bad my customers are complaining. The display has colors washed out and are fuzzy. I even compared this to the previous models on the same display.
T60/T61 both looked good (analog but good)
T400 less crisp and less color
T410 color and line edge are bad.
Anyone else seeing this? We are using discrete graphic versions and it seems as if this is part was made poorly to force adoption of display port. For my company that is a ways off as we do not re-bury monitors with every new system. (Not to mention that Lenovo did not have a monitor with display port until recently)
Anyone else?

I have had fuzzy display with VGA and after numerous phone conversations with the customer support, I had my motherboard replaced last week. Guess what !!! The problem is not resolved. I still have the fuzzy display and it is really annoying.
Despite of having dock (which only supports VGA) I have to use DVI externally and I cannot use external display at work because they all have only VGA...
I always wanted Thinkpad until I bought this T410. And now I say, NEVER AGAIN...

Bluescreen after plugging an external display into my MBP 2012 under Windows 7 6 bit

After installing the windows updates for windows 7 64bit on my bootcamp partition, i always get a blue screen, when I plug in my external display into my mbp 2012. Before installing those windows update, i didn't have this problem. Also, while running osx the external display works perfektly.
The error message says something about a igdkmd64.sys file beeing responsibe for the bluescreen. I've tried to install the original bootcamp drivers and the newest intel graphics driver, neither resulted in a change. Thank you for your help and pleases excuse my bad english ;-)

Hi,
read the documentation:
http://www.oracle.com/pls/db112/to_pdf?pathname=install.112/e24169.pdf
and you will find multiple errors, you probably did.
Especially the part on preparing storage.

Is I-Tunes having protocol issues that prevent installation on Windows Vista 64 bit system?

Is iTunes having protocol issues that prevent communication issues between Windows Vista and the iTunes Store? How can I talk to a warm body at Apple that knows something about this issue? Suggestions?

Thank you Bob.
Just to clarify - in terms of backing up one set of these, would that just be so I had it on disk and didn't need to re-download from Adobe if the installation got corrupted somehow? Or do I need a backup for some other reason?
Thanks
