Thunderbolt-VGA problem

Hi,
I have a MacBook Air 2013 and have recently bought a Thunderbolt-VGA Adapter. However when I connect it to the beamer which I use at work (Panasonic), nothing happens - the blue screen projected by the beamer just remains there!
I have then tried with another adapter from the person which held a presentation there after me and it worked! Therefore my question:
Are there different VGA Adapters for Macs? When yes could you tell me which one I should buy? Or is my adapter just not working?
Regards

It isn't so much different VGA adapters, but some Displayport adapters are not Thunderbolt aware, as Thunderbolt was developed later. Is there no DVI or HDMI on the Panasonic? Much higher resolution ranges are possible with DVI, and HDMI also includes the possibility of audio transfer over the same cable.

Mac Mini and thunderbolt/vga to LCD TV

Hi All,
Here is an interesting one......
I have just taken delivery of 5 new Mac Minis which have the thunderbolt port on them. The Mac Minis each connect using displayport tb/vga adapter to a switch then on to 5 LCD TVs.
The HDMI/DVI is not used.
In this config, if I start a Mac Mini the display will not route through the Thunderbolt/vga adapter to any of the TVs (even though I have selected them on the switch). The display seems to want to go through the default HDMI port.
If I connect a standard PC monitor to the tb/vga adapter and reboot, the screen shows correctly on the monitor. If I then change cables without a reboot, the LCD TVs show correctly!
I can add the PC monitor as a second monitor using HDMI/DVI and ensure that the outputs are mirrored AND that the VGA display is the primary. However, on reboot it's as if the details are all forgotten!
Searching around it seems that there are issues with Mac Minis and VGA connections to LCD TVs. That said, I wanted to put my environment out there and see if anyone had an ideas.
Interestingly enough, with older Mac Minis (without the tb/vga) it works perfectly well, indicating a problem with the new Mac Minis.
Thanks for ANY ideas!!!!

Hey Spost!
You have explained exactly what happened to me last night. I was afraid it was part of the 10.8.3 update or the latest ATV software update that hit this week. I tried from my macbook pro and the airplay from 10.8.3 and the atv software worked fine.
Previously my mac mini was connected to a monitor in my basement but last night i made it "headless" and moved it to my "server closet" airplaying prior to the move worked great ... then last night 4:3 Green Screen.
My guess is the computer needs to be connected to a external display in order for airplay resolution to figure itself out. Via Logmein i could see that the Mirror mode wanted to use the resolution that fit the mac and not what was best for the Apple TV ... Even forcing the change made the setting go right back to this mac.
Looks to be a bug in a plist file that apple would need to fix as many people run headless mac mini's and now wish to AirPlay to their Apple TV's without the need for a external cable run.

Thunderbolt VGA adapter drivers on Windows 7

I am now using MacBook Pro 13" Early 2011 and I installed windows 7 on it. Everything works fine except the thunderbolt for the secondary display. So, can someone help me give links to the driver? Thanks

I also have a thunderbolt VGA adaptor for my 13" macbookPRO. Works well connecting to a 19" monitor but not when connected to my Sony TV. My VGA cable works just fine between my PPC mac mini and the Sony TV. Am I missing something?
Is there some something I have overlooked? I have had a number of Macs over the past many years and almost always find that I am the problem not the equipment.

How to get screen content onto external VGA screen? Do have thunderbolt-VGA adapter but only get screensaver across

how to get screen content onto external VGA screen? Do have thunderbolt-VGA adapter but only get screensaver across

VGA and DVI do not carry sound. Only HDMI.
Use a minidisplay-to-HDMI adapter. Then when the TV is connected to the system use "System Prefences > Sound > Output" to select the TV for sound.
Or connect speakers to the output port of the MBP.

Imac thunderbolt -vga

just got a thunderbolt -vga adaptor but on the old tv im trying to use as a secondary monitor i am getting a "no VGA signal"

Thunderbolt isn't found on PPC Macs. It wasn't introduced until 2011. So I can only assume you have a newer Mac. iOS is the operating system found on iPad/iPod/iPhone, or iPod Touch. Using an old TV for a secondary signal is not really wise, as Mac OS X requires a lot of real estate. Old TVs that only support VGA only support 720 x 480 resolution.

11 inch macbook air and thunderbolt have problems

why would my 11 inch macbook air when connected to a thunderbolt have problems running web based video? and get very hot after about 10 minutes.

What version of the Mac OS are you using? (Look under the Apple menu and select About this Mac). What version of Mac Office are you using?
Office 2008 and Office 2011 are compatible with Mac OS 10.7 and 10.8 (Lion and Mt Lion). Previous versions are not.

Thunderbolt to VGA problems.

Folks, I just setup two Mac Pro computers (late 2013 cylindrical model) and am having problems on both with Thunderbolt to VGA adapters. I get a line at the top of the screen that flickers at a constant rhythm of sorts and the desktop doesn't fill the screen. In fact the dock is pushed a little down beyond the edge of the screen.
I have two 24" monitors plugged into both computers. There's no problem with anything plugged in via DVI or HDMI, but it does affect these two brand new out of the box Samsung and HP monitors connected via Thunderbolt to VGA adapters.
I found this link and firmware to try and remedy the problem, but when run it just said it couldn't find a supported MiniDisplay Port to VGA adapter.
Any ideas folks?

I suspect that the firmware is only applicable to one specific brand of adopter.
I have used Apple mini displayport to VGA adopter on my 2013 Mac Pro without problems for 1080p like your HP monitor.
I suspect a problem with the adopter. However, try resetting the SMC and PRAM
Intel-based Macs: Resetting the System Management Controller (SMC)
About NVRAM and PRAM
otherwise try another brand adopter. I would try min displayport to either HDMI or DVI if you can get them and get the right cable

I am using a minidisplay port to VGA adopter for my 20102 Mini and have no problem.
Try resetting the NVRAM

Urgent need of assistance, MSI Z77A-G45 Thunderbolt Unknown problems

Recently I have built my first computer, a desktop with the MSI Z77A-G45 Thunderbolt motherboard, an Intel core I5 CPU and a NVIDIA Ge-Force GTX 650 TI Video Card, and a 850W PSU (way more than what is needed). The computer worked perfectly fine for about a week, I did not initially order a Disc Drive because I figured I could install windows with a flash drive (which apparently does not work) so I installed ubuntu for a while (irrelevant to the problem) I ordered the Disc Drive and when it came in I plugged it in and the computer would not turn on, so I spent a while trying to figure out why it did not turn on when the day before it worked fine, eventually after basically disconnecting almost everything and putting it back together it worked. But it had no signal to the monitor. I have no means of telling if it is a UEFI/BIOS problem, a video card problem, or a CPU problem. All 4 LED's for the CPU phase are constantly on, when before when the computer worked fine it would only have the first phase LED blink, so I believe it might possibly be a CPU problem, though the video card is what controls the output for monitors so it equally could be the problem. For the motherboard I tried just about everything to reset it, everything, except flashing the BIOS (which I don't want to try unless it is the only solution left) I tried to clear the CMOS, took the BIOS battery out and put it back in again. Please help!

I do not yet have access to another desktop in which to put my graphics card. I just tried reseating everything and still no signal to the monitor. The VGA port on my motherboard does not work, it never has for some reason, I did not get intel integrated graphics with my CPU, I am not sure if that is why the VGA does not work.

Mini DVI to VGA problem

Hello,
I just recently bought the mini DVI to VGA adaptor for my new MacBook because I wanted to use my laptop as a dvd player and plug it into the TV in my room. The TV is a Samsung LCD ln S1951W, when I plug it in the computer detects the display but the TV still flashes the no signal thingie. I've tried it with a proyector and it works fine. It's not the vga-vga cable because it works fine when i connect my iBook. Could anyone help me fix this problem please?

If you are just using it for that specific screen (just for the moment use a workaround). I have the same screen.
Download SwitchResX and make the following setup under "Custom" 1360x 768 at 60Hz. Restart for the settings to be available. It should solve the flashing problem for this specific screen.
If you don´t want to pay for SwitchResX, just check that the new resolution settings are available in the normal mac display options (which they should) and unistall it... the settings will be stored and you can use them indefinitely.
Wait, just re-read your post, you are not getting any signal at all? Then I have no clue if this will solve it. Try it anyways.
Cheers.

Mac Mini mid 2011 Mini Dvi to VGA problems

I have a mac mini mid 2011 and I have to connected to a display in work. The display only has a VGA entrance, so i bought a mini dvi to vga adapter from my local mac store, but when i connected to the display everything looks odd, the whole display has an odd purple look, I have tried to use a different VGA cable but keep having the same problem, I even tried a different display with the same results, anybody knows why this happens and how to fix it?

Your welcome!
On your end before returning the Adapter,
try > Resetting the System Management Controller
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Wait fifteen seconds.
4. Attach the computer's power cord.
5. Wait five seconds, then press the power button to turn on the computer.
and > About NVRAM and PRAM
1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6. Release the keys.
then if that doesn't help, return the adapter and explain the problem to the Apple tech person at the store.

Mini DVI to external monitor (VGA) problem/firmware update does nothing

Hi,
Four months ago I bought a new white 13-inch Macbook (2006 model I believe) along with a handy mini-DVI - VGA adapter. I used a Hanns-G HU196D external monitor which worked fine for a couple of months but then stopped, and had the same problem with a (much cheaper) 'LiteView' monitor. I find it bizarre how they work absolutely fine and then stop, with no damage to the adapter, cable or ports. I've since bought a new adapter and cables + trying out a different monitor and still the same problem...
I've installed a firmware update that describes the exact symptoms, but it's done nothing. Can anyone help me resolve my issue?? It's still under warranty so is it an unusual problem that'll need to be fixed by Apple?
Thanks

Are you using the mini DVI to DVI followed by a DVI to VGA adapter? That may not work if the mini DVI to DVI adapter does not pass analog video. If that is the case, you need the mini DVI to VGA adapter:

Mini Displayport to VGA problem - not recognizing

Hi all,
First, thanks for your patience as I am new to these forums and thanks for reading and hopefully helping.
We purchased an apple branded mini DP to VGA adapter about a week ago from an auth. reseller in Prague (US expats). We are using the adapter to watch video from our MacBook Pro on an Epson projector. Everything worked great for about a week and all of a sudden (truly, no software changes, updates, dropped adapters, etc. etc. etc.) it stopped working. By "it" I think I mean the mini DP adapter or the plug itself. The reason I think this is b/c the computer doesn't even recognize when the adapter is plugged in; previously, when plugging ONLY the adapter into the mini DP plug, the screen would flash blue, now - nothing.
I have reset PRAM and the SMC and still no change. I checked when I first purchased the adapter and found that the firmware was indeed up to date.
Any ideas? Hoping for insight before having to deal with the extraordinary language barrier.
Thanks again.

Mini DisplayPort to VGA problem

Hi, all!
My New MacBook can't work with external display with resolution more then 1360x768 using Mini DisplayPort to VGA connector.
Then I'm setting bigger resolution (for ex. 1920x1080) display shows me picture for a 2-3 seconds, then switches off, and on again.
Tested 3 monitors and one tv.
Any suggestions?
