Imac - dvi to hdmi. It works great, but I have one problem with blue flicker on my imac
Yesterday I bought a dvi to hdmi connector from Apple store, and successfully connected my iMac (10.6.8) to an LG 50" monitor.
It works great with one problem. My imac flickers blue every 2 secs when TV is on but set to other inputs.
We use the TV for other things (TiVo, DVD) as they are HDMI1, HDMI2 and the iMac is HDMI3.
I tried several things, and each worked with Audio and Video. I currently have it setup as seperate screens instead of duplicating the screens, but each worked fine. And each had the same problem below.
The problem comes if I am on the iMac and then turn on the TV to watch something. As soon as I do, my iMac display starts flickering blue every 2-3 seconds as it is obviously talking to the LG TV. As soon as I set the TV to HDMI3 everything works. If I turn the TV off, everything works.
I don't want to have to connect the cable every time I want I want to project to the TV (although I guess I can live w/ that). Is there a way to have this setup correctly?
thanks for any help in advance.
As an update, after 2 weeks of tinkering with this setup, the iMac is usually able to settle down after about 20 seconds of flittering. And, if it does happen where the iMac stays blue screen, I can switch the TV to show the HDMI input from the computer, which works, and if I want, switch it back.
So, all in all, it works very well. I just needed some more patience.

I have a problem with dust on the monitor (iMac 27).
I have a problem with dust on the monitor (iMac 27). it appeared after half a year of use (in a clean room is not dusty). Replaced by a matrix of times under warranty. But after a while, again, there were shortcomings in the upper corners of the matrix. The guarantee is no longer valid. Am I entitled to free replacement of the matrix or the display?
Re: I have a 27" iMac that has developed smudges at top left and right of the screen. Of course it has just gone out of warranty. Anyone had a similar problem or found a solution?

Trouble connecting to itunes store with my password on my ipod touch (2nd generation) but using the same apple id and password on my ipad2 I don't have a problem connecting to the store.
Need troubleshootingI have the same thing, same issues. Just came from Colorado using my iPad extensively with no problems.
Get back home, there is an update on my home computer for Airport Extreme to 7.5.2 which I updated. Also updates for iPad for 4.3.4 and now last night 4.3.5.
Still does not work. I have not taken the iPad to another network locally, but my understanding is that it is not a problem with the iPad but with Airport Extreme's update. I have done all the resets, restarts, and turning on and off Wifi on the iPad and that does not work.
I would have to assume Apple is working on it. Very frustrating since I am on my Mac Pro, iPhone 4, and other things and no problem. -
New 4s connected to my Lexus bluetooth. Having intermittent problem with calls. I can hear them, but they can't hear me. Never a problem with 3gs phone. Anyone else having this problem?
I ended up getting a new phone, straight through Apple. I called their technical support and went through all he basics again and they decided to replace it. Was a pretty quick process - after defaulting and resetting the whole phone (about 2 hours), I called them back to inform that there was no change, so they set up the order.
I had to give my CC# so they could hold a charge on it (in case I didn't send my old phone bach, which they sent me a pre-posted package to send it in anyway). Had a brand new iPhone 4S in my hands in 4 days, which was pretty decent. I had uploaded everything previously to iCloud, so setting up the new phone was a snap.
Only thing I really didn't like was they charged me almost 30 bucks for shipping or processing, or something. Not so sure that should have been my responsibility after spending so much on a brand new product, only to have to have it warrantied after, like, a month. -
Hello, I have the usual issue to use AcroExch.PDDoc/AcroExch.App/AcroExch.AVDoc objects in Visual Basic (MS EXCEL). On my company's machine I have Acrobat X and everything works fine. I am looking for the cheapest solution to get the stuff running on another machine... is there any way to do that with the Acrobat SDK, or do I need to purchase a full version of Acrobat XI ($$) ?
The Acrobat SDK is nothing by itself. It is just information on how to automate Acrobat - just as the Office SDK doesn't include Office, but is for people who already have purchased Office but want to automate it.
These automation things are MARKETING TOOLS FOR ACROBAT. Consider this and the technical limitations make a lot more sense.
So, yes, you need to buy Acrobat. Standard is cheaper than Pro. -
How can I make this problem work!?
Return it for a credit. Buying things like phones and computers on eBay is not a good idea. If the person refuses to refund your money, use the eBay appeal process since you were sold something that does not work.

HT1338 i have a problem with my iphoto on my imac
because now every time i import the picture from my iphone or ipad, the iphoto program does not automatically separate the event any more instead it put every pics in the same event even though the pics were taken on different day. I think it started to do that after I update the software last time. Does any one know what is going on? or how to fix it?
Automatic imported into PhotoStream go into a single event by month
Photo imported via USB are split into events based on the criteria you set in the iPhoto preferences
Unless you what your work flow it is impoossible to guess what you are doing pr what is wrong

Why won't my macbook air connect to my wifi, but I have no problems with other devices?
I can't seem to connect my macbook air to the internet. I have no problem with my regular mac. What could the problem be?
Let us know what any error message is. Otherwise some general things you can try is creating a new network location in System Preferences > Network. Also you can reset the network settings by deleting /Library/Preferences/SystemConfiguration and restart the computer.

My thunderbolt to hdmi cable worked once but then stopped
so i bought a thunderbolt to HDMI adapter and it work great but when i took out the hdmi and put it in my console id didnt work when i checked if it would work with the adapter is didnt so this adaper stoped working a broke my HDMI cord
Hi, how did you solve your problem? Im having the exact same issue.
"When connected to the TV via the Thunderbolt-HDMI cable, a blue screen briefly appears on the Macbook. However, when looking in System Preferences/ Displays, there is no trace of any external screen. Many of the forums I have read say there should be an "Arrangement" tab, but this is not appearing on mine."
plus the cable works on my boyfriend's Macbook Air, which is an older version than mine.
I have the Macbook Air Version 10.8.4, bought July 2013 (newest version).
Can someone help me?
Thanks -
I cannot send an email from my iPad 2? No problem receiving, why does this happen? Have tried the suggestions for setting up email and after doing the sync mail through iTunes receiving worked great but still cannot send? Any help would be great!
The fact that you can receive means you have a valid e mail address, and have established the connection to the incoming server, so all of that works. Since the send does not work, that means your outgoing server is rejecting whatever settings you used formthe outgoing set up. Try them again.
Google your particular isp, and ipad and many times you will find the exact settings needed for your isp. Or tell us here, and soneone else may be on the same isp. Some mail services need you to change a port, or have a unique name for the outgoing server.
Kep trying.
