Lighting to HDMI Adapter Not Working

I am using an Apple Lightning to HDMI AV adpater (Model A1438, Firmware 7.0.0 {11A7451}, Harware 1.0.0) with an iPhone 5 (MD655LL/A) and iOS 7.0.4 (11B554a). With two different adapters (same version) we seeming to have suddenly lost the ability to mirror using these adapters. Having been able to mirror since the recent iOS update we are puzzled. Any ideas on why this would be happening?

I don't have the same ThinkPad as you (I have a T410 with discrete graphics), but I DO have the same Monoprice DisplayPort to DVI adapter, and I can confirm that it does work, when connected via a DVI cable to a Viewsonic LCD monitor. I did notice that, when the monitor goes into power-saving/sleep mode, the laptop won't recognize it when the laptop resumes from sleep. I had to toggle the monitor power swtich off/on, and then select it with the laptop's Fn-F7 hotkey (the laptop utility calls it a "projector"). So, you might have to fiddle with that.
By the way, my 19-inch Viewsonic LCD shows just how crummy the ThinkPad's LCD is, by comparison. The image via DisplayPort/DVI is fantastic. The NVIDIA control panel confirms that the ThinkPad<-->dongle<-->DVI cable<-->monitor connection supports HDCP, by the way, so it'll play protected content.
When I get around to it, I will also try plugging the ThinkPad into my TV via the similar MonoPrice HDMI / DisplayPort dongle.

My hdmi adapter not working anymore, no physical damage. Solution?

My hdmi adapter not working anymore, no physical damage. Solution?
Strange is, that i used it several times, it worked fine. Then wothout any reason (like software updete, etc) it just stopped workung, no sync.
I have not changed any parameters of my TV or Beamer.
Hardware:
Ipad 2, Apple Ipad HDMI Adapter, Samsung P2770FH, Optoma HD 65.
Thanks for any help.

I've only used mine a couple of times without any problem, but due to the thinness of the iPad, care has to be taken in inserting the adapter. Slightly wrong angle and it won't go it.
I had a laptop a few years ago where the USB connector failed. I had it replaced under the warantee, The service man told me it was not an uncommom failure on a laptop due to people "torquing" the USB socket while inserting/removing USB items. I have much the same feeling when inserting either the charger cord or my HDMI adapter.
From your description, unless the HDMI adapter failed internally, it sounds like the socket is causing the problem. A few days ago we watch our first movie from the iPad via my ATV2 and "Air Play". Worked great so I don't plan on using the HDMI adapter much at all in the future. Yes, it is a $99 solution, but it works for me. Of course, I already had the ATV2. I doubt if I would buy one just for this abiliity. If nothing else, it seems like a trip to the Apple Genius bar is in order for maybe a replacement unit.
However, with iOS 5 coming out with supposedly total mirroring, it might be worth thinking about getting an ATV2.

Lightning HDMI Adapter not working with iOS 6.1.2

I have an iPhone 5 which was updated from 6.0.2 to 6.1.2 recently and the Lightning HDMI adapter stopped working altogether for video mirroring; was wondering if anyone has the same situation/any solution for this?
I also have an iPad retina generation which is at 6.1.2, and the Lightning HDMI adapter is not working for it as well.
I've tried replacing HDMI cables, rebooting the iPhone with the cable plugged in, and plugging out/in several times with the charger in/out. The adapter works, cause when I plug it in; I see the top bar flash for a bit... but no dice on the video mirroring to my TV.

I also have this problem and am very unhappy with the way Apple is handling it. Called today to enquire on when the fix will be available and was told it is a software issue that could be fixed if we paid $35.00 to talked through process on the phone. Highly disappointed with Apple, why should it cost me money for them to fix there own issue. Since they are aware of the issue the least they can do it posted the information for the fix online @ no charge.
If I wanted crap service I could have gotten a phone from anyone. Reconsidering purchasing a 5 on next upgrade.

Mini display port to HDMI adapter not working

I can not get my MacBook OS X to dispaly on my new Samsung LED TV. I have a mini display port to HDMI adapter (two years old) conneted with an HDMI cable (new) into the HDMI input on the TV. I tried both inputs, tried resetting the TV, plugging, unplugging, restarting, checked all my system preferences...I can not figure it out. I took my cables to a local store, tested the HDMI cable, and it works. Tested the adapter and they had the same problem I have on my Mac. The screen will flash blue when you plug it in, but will not show up in the TV. I think the adapter must be bad, nothing else makes sense???

Hi Kater24,
Apple doesn't make a Mini DisplayPort to HDMI adapter, so the one you've got there is a 3rd party one that's designed to work with the Mini DisplayPort on your Apple computer. The adapter is pretty much plug-n-play, there's no configuration necessary. Plug it into the machine, the HDMI cable from the other end of the adapter into your TV, select the HDMI input on your TV and fire up the computer.
If that's not working it's possibly an issue with the adapter and/or cable to the TV. Any chance you might have access to another TV for troubleshooting purposes?

Mini DisplayPort to HDMI Adapter Not Working

I just got a mini displayport to hdmi adapter that I ordered from dealextreme and it does not work. The adapter had very good reviews and not one review said it didnt work. When I plug in the adapter (with or without a hdmi cable attatched to it) to my macbook, the screen blinks and then goes back to normal. When everything is properly connected the tv shows no input signal (I am on the correct input channel) and the screen doesnt appear in the displayas settings in my macbook pro. I tried to reboot the macbook, shut down and turn on the screen and nothing seemed to work. The detect display option in the system preferences didnt help. I appreciate any help I can get.

Thunderbolt to HDMI adapter not working

I just purchased a 13 inch macbook air and when I use my thunderbolt to hdmi adapter my Samsung monitor along with my other displays do not recognize my mac. How can I get my monitors/displays to recognize my device? Do I need software to get this working?
I am using an amazon high speed hdmi cable with ethernet. Will that effect my connection?

I finally learned how to get "Detect Displays" to show up. You have to press the Option key while in the Display pane.
Unfotrtunately this does not work. No other displays are detected. Yes, the TV is on and plugged in to my computer.

Hdmi adapter not working after upgrade to iOS 8

My Hdmi adapter (orig. Apple) is not working anymore after upgrade to iOS 8, is there any solution.

The IOS 8 update has nothing to do with the failure of the device. I have a HDMI adapter and it has worked fine through IOS 6, IOS 7 and IOS 8.
You may want to restart your device by holding the home and power button until the Apple logo appears. If the adapter still fails to work you need to determine if the adapter has failed or the port on your device has failed. Best solution is to go to the Apple store with the device and the adapter. If your adapter has failed it may be under warranty if you still have the sales receipt. If the port on your device is bad then the Apple store will be able to provide you with options.

Macbook Air HDMI adapter not working

I know there are other threads about this but they are a bit outdated. So anyway I bought an hdmi adapter for my macbook air and it was working perfectly for about an hour and a half when suddenly the tv registered "no signal" yet the macbook was still saying it was connected to the tv. I thought it may have been a problem with the tv so I tried on another tv in the house, same result. So then i thought it may be the hdmi so i switched them, same result. So now the only problem could be the adapter or my laptop, does anyone know how I can fix my problem???

Greetings obomb2000,
Thank you for visiting Apple Support Communities.
It sounds like your MacBook Air is not outputting video to your TVs using an HDMI adapter, and you've done a good job of isolating this behavior to either the adapter or laptop.
Here are a few additional steps you can try on your MacBook Air before trying another adapter:
Reset the system
You can reset the Mac's parameter RAM and SMC.

All the best,

DisplayPort to HDMI adapter NOT WORKING!!!!

I have tried and tried and can't get this working. I'm on a T500 and running Windows 7. The T500 just doesn't recognize the external monitor when I have the displayport to hdmi adapter plugged in and an hdmi cable running from that to the external monitor.
HELP PLEASE???

Hdmi adapter not working after upgrade to iOS8

I Had used an hdmi adapter to comment my iPad2 to my TV with great ease. After upgrading to IOS 8 I plugged it in as ususal, the screen popped up on the TV for a moment then the TV went blank and I got an error on the pad that said this device was not supported. HELP!!!!

I have iPad 2 it just happen to me right after I updated to IOS 8 but it has happen to me before in IOS 7. I have Sony TV to fix it I would shut the TV off unplug then plug the HDMI adapter back into the IPad then turn on the tv. It still has back screen then I would touch the screen for input then the picture is on . Sometimes I would have to do this couple times . I would go months without any problems then the message would show up then I would have to do the something over again. Do not know if it's the Sony TV or the IPad not communicating with each other. The HDMI adapter I have is from Apple.

Why does my digital AV adapter not work with my iPad

Hdmi does not work since updating to jelly bean

Since updating my at305-16 to JB hdmi will not work . I go into settings and select hdmi out but get no signal on tv.

I think it might be a JB driver issue. I was having the same problem connecting it to my LCD, but when I switched to my plasma it works. The LCD is 1080P Auto the plasma is 720P auto. But fropping my LCD to 7120P didn't help. I don;t know if you have two TVs to try on, but it couldn't hurt.

Mini-Displayport to DVI adapter not working, but Mini-Displayport to VGA and Thunderbolt work fine

Mini-Displayport to DVI adapter not working, but Mini-Displayport to VGA and Thunderbolt work fine.
This is a brand new MacBook Pro (15-inch, mid-2012) just received. I suspect that this is a hardware problem as:
The mini-displayport to DVI adapter and the external monitor that I am utilizing connect and operate just fine using my older MacBook Pro (mid-2010) with the same OS.
The new MacBook Pro powers the external monitor with a mini-displayport to VGA adapater without issue.
The new MacBook Pro powers an Apple Thunderbolt display without issue.
Both MacBook Pro's are running OSX Lion 10.7.4.
The only combination which does not work is the mini-displayport to DVI adapater used in conjunction with the brand new MacBook Pro (mid-2012).
All adapters and components (mini-displayport adapters) are Apple retail adapter.
I have tried several external monitors, including my Dell U2412m.
When I connect the mini-displayport to DVI adapater to the new MacBook Pro (mid-2012), nothing happens. The external monitor reports "no signal" and attempts to go into sleep mode. Using the "Detect displays" button has no effect, even when used multiple times. Rebooting does not help, nor does resetting the SMC or PRAM.
Any other suggestions before I take it to the Genius Bar?

I turns out that the logic board of my MacBook Pro was faulty (despite being brand new).
I took it to the Apple Store, presented the problem, and one of the Tech's came to the same conclusion that I had -- hardware failure. Phone support was no help in the matter (and even told me that what I was trying to do wasn't a supported option, which is rediculous). However, the Genius Bar did take care of the problem, and my MacBook Pro was back to me with a replaced logic board within a few days.
Hope that htis helps.

G5 dvi to vga adapter not working

DVI to VGA adapter not working with my G5 Dual 2.3 GHz Power PC. I am trying to use a VGA Monitor but can not get a signal. I also am using a Dell with a DVI Input and that works fine using a DVI Cable from my G5 to the Dell u2410.

Bad adapter?
The G5 ports are DVI-I. Any good DVI-I to VGA adapter should be fine.

StarTech Adapter not working with Dell Inspiron 15, model 3521

Side Note: I wrote a reply to a thread that was from 2013. I do apologize because the link was sent to me by my bf and I did not realize how old it was. Since my reply has to be approved I can't delete it.
Current Issue: StarTech Adapter not working with Dell Inspiron 15 model 3521
I bought my Dell laptop last year and at first I did not realize that it had only one audio jack (combo, as the specifications manual says), I only noticed when I was trying to plug in my Ozone Rage ST headset.
I searched online threads and found out that I needed an adapter and most people mentioned Headset Buddy. I couldn't find any adapters for sale in my country (or employees didn't really know what I was talking about) and since Headset Buddy is a bit expensive, I decided to try StarTech Headset adapter for headsets with separate headphone/microphone plugs - 3.5mm 4 position to 2x 3 position 3.5mm M/F www.amazon.com/.../ref=cm_cr_pr_product_top.
It arrived today and let me tell you that I can't make it work. I can hear everything but I can't get the external mic to work or even be detected. I have always used my headset (mostly for gaming) and I prefer to use my external mic rather than the internal one. First I connected my headphone and mic jacks to the adapter and only after that did I connect it to the laptop combo jack. I also tried vice-versa. It didn't work, regardless of the order. I even tried with a different headset and it still didn't work. What else can I do?
I have also found a thread on Dell forums saying that Headset Buddy doesn't even work on Dell Inspiron 15, model 3521. So since it doesn't work and I'm assuming StarTech doesn't, either, what am I to do/buy?! I am getting extremely frustrated and I'm very disappointed with Dell because the brand should have included with the laptop a proper working adapter for these situations and not make its customers buy an extra accessory to make whatever working gear they already had function. It just doesn't make sense to me! Either make the changes work properly or simply don't touch anything. I spent some of my savings on this laptop which, overall, is great but now I am being forced to spend more on an item to allow me to use my headset. I am running out of options here and even Dell can't seem to tell its customers with 100% certainty what really works for this specific model.
If I can't make the adapter work, I just hope I can return it, otherwise I'll end up with no refund and with a piece of equipment I have no other use for!
Any thoughts?

Hi,
Thanks for your reply.
This is the first time I was forced to buy adapters such as these so I don't know if I'm doing something wrong or if there's anything else I can do to make it work. When I plug the adapter to my Dell, the laptop presents me with several options such as: headphones, headphone, speakers, skull candy headphones, etc (maybe some may have different names but since I see them in Portuguese, I'm not quite sure how they appear for someone who has the computer in English), I have picked different options and it still doesn't work, the only noticeable changes are sound quality related, I guess.
