VGA Adapter Issues

I bought a VGA adapter for my iPad1 so that I could project the web browser to a screen for demonstrations.
Can anyone help me figure out how to get this to work...so far no luck?

Hi DoDolom,
First, welcome to Macintosh!
Secondly, it sounds to me like what's happened is that OS X has extended your desktop onto a second monitor. Plug in an external mouse and keyboard and then close the MacBook's lid. It will go to sleep. Use the external mouse/keyboard to wake it up and you should be running on just the external display.

External MiniDP/TB to VGA Adapter Issue

Hi,
I work for a university in the classroom technology department. We have over 220+ classrooms on our campus utilizing technology. We utiltize a handful of models of projectors as well as VGA switchers/control systems.
It seems recently, in (so far) 5 of our classrooms, Mac laptops (faculty personal laptops) and a desktop (permantly installed in one of the rooms) are no longer connecting to our external displays. All Macs involved either have 10.8.5 or 10.9+.
Thankfully, in all situations so far, an "active" miniDP to VGA adapter fixes the issue. Most faculty own the Apple branded one, which unfortunately is not "active".
And the strangest part, some of these same laptops work in some of our classrooms. So I know it could be some component of our systems and something with how the latest OS versions handle the "handshake" between computer and display...
Here's how all of our systems hook up:
3 Devices (usually PC, Laptop, Doc Cam) ---> 3x1:2 VGA switch/splitter ---> 1 output to monitor, 1 output to projector
The VGA cables are normally from Monoprice.com which have served us amazingly well for years.
Any input would be helpful and appreciated. We'll continue testing for other similarities between rooms.
Oh the world of technology

Hi Greg,
Typically when colors are off or alignment is off centered there's usually a bent or missing pin somewhere. Each pin carries a specific color and signal between the machine and the monitor. I'd inspect each pin on the cable from the monitor and make sure that everything looks aligned and normal.

Mini DVI to VGA Adapter Issues

Hey guys,
My first ever post to the forums. I just recently bought my very first apple computer. It is a 2.4 ghz Macbook 13" and bought a Mini DVI to VGA Adapter so that I can connect it to my 46" Sharp AQUOS TV. I connect my laptop with the dvi to vga adapter plus another vga cable of course and all I get on the screen is my wallpaper but I can't see any of the icons on my tv screen, nothing.
Can anyone help me on this? Does this sound like a familiar problem?
I would appreciate your help.
Thanks in advance,
Dogan

Thunderbolt to VGA adapter issues

Hi guys,
I have bought a THUNDERBOLT TO VGA adapter to duplicate my screen on my TV, but when i plug in it my TV doesn't show anything. It shows just "Control signal", but I don't know how fix this problem.
Could you help me?
Thank you !

I have this same problem, discovered today in front of customers, when hooking up to their VGA projector. The VGA adaptor did not work very well with OSX either so running Windows under Parallels did not work either. Back in the office, I experimented with our old VGA projector, same problem, but I could get OSX to display and thus Parallels. Back on the Win 7 bootcamp, resolution is grayed out and set to 640x480, too small to do anything. I tried another sugestion of updating the Nvidia driver in Windows, to the latest version but that did not help. The only other suggestion that worked for others is to get a USB3 to VGA adaptor. Aparently Apple needs to update their bootcamp drivers for the mini display/thunderbolt port. So until that happens, perhaps the USB3 adaptor will be the way to go. I'm going to order one now since I cannot find it in the local apple stores or Best Buy.

VGA Adapter Issue

Does any one have any clue how to get the ipad to transmit video when hooked up to VGA (via its adapter). Yes all connections are fine and I am on the newest IOS release. I assumed that it could be mirrored, any ideas?
Thanks

Let's start with the basics; what model of iPad to you have and what version of iOS is it running?
For replies and future posts, the default font used in the forums will be just fine. Using a font that's much larger just makes your post more difficult to read.

Mini DVI to VGA adapter issue

Hi, I'm having a problem connecting my second monitor to my Mac... it connects and I see the SL desktop, but the colors are funky. Everything is either way too red, or if you tap the adapter it will turn to a blue. It's a heavy hue that's hard to work with. The calibration has no help. Any ideas?

Macbook air Mini DisplayPort to VGA Adapter connectivity issues

Hi pple,
Would like to ask if anyone is facing connectivity issues with Mini DisplayPort to VGA?
I am currently using the 2nd Gen Macbook Air with Intel HD Graphics 3000 384 MB. Sometimes when I connect to a montior (Viewsonic VA1918wm) it works fine, sometimes it just does not work and the laptop just shows me a blue screen.
I tried with out with my friend's Mini DisplayPort to VGA adapter, it has the same problem. Does this means that my macbook air mini disoaly port got a problem?
Thanks
Bryan

I am experiencing the same kind of problem... only with projectors. Some projectors will display the screen and then others wont even register with the MacBook Air.
Using an Apple Min Displayport to VGA adapter. It's hit or miss if it works. Firmware has been updated on the adapter but this did not help.
Anyone help with this?
Thanks,
Nathan.

Mini Display Port to VGA Adapter Having Issues with My Samsung 40" HDTV

So I ordered the brand new 15" i7 Macbook Pro along with the Apple wireless magic mouse and wireless keyboard after having bought my HDTV (went on a bit of a spree) with the intention of using the TV as a monitor for couch surfing. But, upon hooking up the adapter to the TV, my macbook's screen flickered between that blue transitionary screen and it's desktop screen. It did this for a few minutes. I jiggled the cable thinking that there was a loose connection somewhere as that was the problem with my previous mini DVI to VGA adapter from Apple. I did a little research and it turns out that they released a firmware update in 2009 for such a problem. I downloaded the update and attempted to install it but it did not determine that there was even an adapter connected. So, I proceeded to call Apple, they man was very calming to talk to and make all of my problems seem to melt away, but there were no solutions reached. He thought that maybe my TV either had a problem or was incompatible with the adapter (incompatible with a VGA connection? can you get any more analoge that that?). So, here I am, the adapter seems not to have a problem with regular monitors but I am still experiencing intermittent disconnects from my TV. I still, superstitiously jiggle the connection whenever I have dropouts but that really doesn't seem to be the issue here (or at least I hope not because that could mean port issues with my new laptop). Any suggestions? I noticed, after changing some settings on my TV, in an attempt to remedy this, that the TV was displaying the picture funny, I turned the TV off and then on again and it fixed the problem. That being said, perhaps I just need to turn my TV completely off when I'm not using it, as I have been just letting it go into standby. Maybe it needs a restart every so often much like my computer. I don't currently have data to support that theory as I just recently tried turning it off, but, since then have not had dropouts.

You may have the screen refresh rate set higher than the TV is generally able to track reliably. It may be able to get there most times, but occasionally loses sync because it is out of its nominal range.
I suggest you sit down with the manual for the TV and find out what resolutions at what refresh rates it intends to support through VGA, and make sure your screen settings are near (or below) those limits.

Thunderbolt and MDP to VGA Adapter Compatibility Issue?

Hi Veterans,
I know this topic have been asked a lot of times by different people who faced the issue in different way. However, i am unable to find an absolute solution to the problem i am facing currently.
My question is, can a 3rd party made, Mini Display Port to VGA adapter works on MBP & iMac that have mini display port and not on those that have thunderbolt port??
I have a 3rd party made, Mini Display Port to VGA adapter that i have tried on 3 apple PC / laptop,
A MacBook (13-inch, Late 2009) which comes with Mini DispayPort, the adapter work with this laptop.
A iMac (21.5-inch, Late 2009) which comes with Mini Display Port, the adapter work with this PC too.
A MacBook Pro (13-inch, Late 2011) which comes with Thunderbolt port, the adapter does not work with this laptop. I have tried many solutions i can find on this forum and none helped.
The software is fully up-to-date as of 30 April 2013, running Mac OS X 10.7.5 (Lion).
Tried safe mode, does not helped.
Tried the boot up when monitor is already switched on procedure, does not helped.
In all cases, it was tested on the same external monitor. As my MBP was dual-booted using Bootcamp assistant 4.0, i also tried in windows-mode (windows 7) which didn't work too. In windows mode, the screen just keeps flickering while in mac-mode i get a light blue screen. In both cases, the external monitor shows nothing. The external monitor is a Compaq FP7317 monitor with native resolution 1280 x 1024 at 75.0 Hz.
All these trying have leave me very perplexed. From my research, the thunderbolt port is suppose to accept devices meant for mini display port. So how could an adapter that work on mini display ports, not work on a thunderbolt port? Can any expert enlighten me?

Problem solved. I picked up the MDP to VGA adapter and was able to use the monitors native res of 1920x1200 but the flicker and wavyness made it impossible to use. And yes the adapter had the current firmware. But what I discovered in the process was that in mirror mode I am unable to drive the monitor at optimum resolution. With that in mind I tried the MDP to HDMI adapter again, unchecking mirror mode, moving the Finder bar to the external display and SHAZAM. I have a rock solid display external display now running at 1920x1200 : )

Any issues connecting the new MacBook to LCD projector with VGA adapter?

I do presentations on the road using my old MacBook with whatever LCD I find when I get there. I run Keynote with lots of video clips in my presentations. I carry a Mini-DVI to VGA adapter. Most often it works fine.
I was hoping to update to the new MacBook, but I'm concerned about the display issues on the discussion board.
Has anyone had any experience connecting the new MacBook using Mini DisplayPort to VGA Adapter?

I received my MB (aluminium) 2.0 in early November, but only this week (2nd week December) have had a need to use it for a presentation via the Mini DisplayPort --> VGA adapter.
I thought I could use it just as I did my previous (white 1.83 MacBook) laptop, but this one is a bit quirkier. Plugging in the adapter cable results in a system freeze. Unplugging the cable will restore mouse control (unfreezing the computer) in most instances, but not all.
Turns out that in order to use an external VGA connection, I need to have the adapter plugged in and restart the machine. If the external display is not present from boot, then it freezes.
This is unlike my previous MacBook, in which I could plug-unplug willy-nilly. The screen would flash blue a couple of times and all would be fine, with the external extended display detected and functioning. This was one of those nice "Mac" things that my Windows-using colleagues were somewhat jealous of, as they constantly have trouble getting their laptops to recognize the LCD projector.
Sadly, it looks like I'm now living in their world...

Macbook Pro VGA adapter resolution issue

I have an Optoma projector that has been connected to my Lenovo laptop for the last 2 years. I have just decided to set my mac up to it, and had a mini display port to VGA adapter. The native resolution of my projector is 1280x800, yet when I plug in the mac, I can only get 800x600. If I change it to optimize for the built-in display, I get a scaled image of 1280x800 on what is really 800x600. This has been extremely frustrating and my searches on the web have proven unsuccessful. I have tried the PRAM/NVRAM restart where you hold Option, Command, P + R, and it has not resolved the issue. How can I display the correct resolution, which is exactly the same as the Macbook itself??

Upon more research, I have learned that holding down the "option" key while clicking Scaled in the Display Properties will allow you more resolutions to choose from. I now have the option of 1280x720, 1280x768 or 1280x960, but still not the true resolution which is 1280x800!! How ridiculous! Why can't the MacBook determine the resolution of the projector and use it to its maximum potential the way Windows did?

Apple Mini DisplayPort to VGA Adapter flickers

I have 2 Samsung SyncMaster 23 in, HD Displays connected to my Mac Mini. The Display connected via the Mini DP to VGA adapter flickers erratically. This started happening after installing the latest upgrade of OSX Mountain Lion. I called Apple support, they gave me a list of steps to try to fix the problem, which I followed to the letter, to no avail. The problem is annoying, to say the least. I tried to find out if there was a firmware update for the adapter, but I am running the latest firmware (1.03).
I would appreciate any help to solve this issue.

Thank you for your message.
1. Both monitors only have VGA input.
2. The other adapter, Mini-DVI to VGA has always worked properly.
3. The Mini DisplayPort to VGA adapter is an Apple original product I bought at an Apple store. I bought 2 adapters.
4. Actually I have 2 Mini DisplayPort to VGA adapters: The one I use with my Mac Mini, and another adapter I use to connect my Mac Book Pro to a Panasonic projector.
5. I have tried using both adapters, and the flickering problem is present using either adapter.
6. I believe the flickering problem is definitely something that needs to be addressed and solved by Apple. The adapter is its product, and should work as advertised, no matter what version of OSX I am running. Please remember that there was no flickering before I upgraded to the latest OSX Mountain Lion.
7. I do not believe buying an adapter from another manufacturer, as you suggest, would solve the problem.
Thank you for your help.

Apple Mini-DVI to VGA Adapter Problems in Boot Camp / Windows

I currently run Windows XP SP2 on my MacBook and recently purchased the Mini-DVI to VGA adapter so I could hook up the MacBook to an external projector, monitor, or TV to display what's on my Windows screen on the external device. However, when I connect it to any external device, it just goes nuts and sporadically continues to make the hardware connect and hardware disconnect sounds and doesn't allow for external output of the screen. Any suggestions...? Thanks!
Marc

I think I solved this problem.
It was in issue for me. My second monitor would only display the Windows XP screen when it was loading, then it would black out. I couldn't even move my mouse arrow to the other side. Then I fixed it, here's how (running Windows XP SP3):
1. Start > Control Panel > Appearance and Themes
2. Display
3. Go to tab "settings"
4. Double click the blue image with the "2" inside it. This is the second monitor, adjacent to your first, or primary, monitor. The blue box may be a desaturated, greyish blue, meaning that the monitor is disabled. Click it and it a box will pop up asking if you want to enable the monitor. Click OK, and then like magic, your monitor is resurected in it's Windows Glory! From there, adjust the resolution, and it should work perfectly.
This isn't a Boot Camp compatability issue, it's just a problem with the lack of familiarity that users of OS X have with using XP.
Have a nice day!
