I have a one year old Macbook Air 13. I have a brand new 22" external monitor. When I connect my external monitor it initially provides a nice display - very accurate and no distortions. But, within a few minutes the screen begins a incessant series

I have a one year old Macbook Air 13. I have a brand new 22" external monitor. In turning the Macbook and monitor on, the monitor displays very well, but within a few minutes it begins this incessant blinking (temporary black out of the screen that lasts anywhere from 1-5 seconds). This has been going on for a long time (it also happended with my older monitor which apparantly I threw out when I should have kept it thinking it was the problem). From reading various blogs in the Apple support community, this appears to be a widespread problem, but I don't find a solution, only a lot of speculation. I'm very surprised the Apple folks haven't figured this out. As a new Apple user, heretofor, I have been very impressed with the support and effort to get fixes out to users. This, however, has me frustrated to the point of junking my Mac and going back to a PC. I love the Macbook Air and most of the functionality, but I cannot function without an external monitor. Anybody have any ideas, please help. Frustrated, Jim

Your dsplay is getting extended onto the external monitor. Chcnage the setting to duplicate it or only display on the external monitor and you should be fine,
Let me know if this worked for you.

New Dual-Link Adapter on Gateway 30" Monitor, Thinks DVI!

I have the new dual-link cable attached between my macbook pro and a Gateway 30" Display. For some reason my display is only detected as having a regular dvi cable attached and won't support a resolution higher than 1920X1200. The monitor itself is capable of 2580X1600 and works on a Windows pc this way.
Do I have a defective cable or is there something I'm doing wrong?

Not that it matters, I suppose... But I'd like to know who it is that is diverging from the Dual-Link DVI specification. If the panel works with any brand and model of 'PC' graphics card that supports Dual-Link but does not work with Apple's Dual-Link DVI port, who is really the culprit? That's assuming it's a hardware issue.
If it's a software/driver issue, then I see no reason that this wouldn't be fixed by Apple as other third party hardware support issues are fixed by them all the time. Some might say that Apple ensuring more sales of their own displays is the reason, and they may be right, but I find that a disservice to the end user.
I'm staying steady on with the monitor as on January 9th the real reason for it's purchase will arrive: A Penryn-based PC with 3 Nvidia 1GB GTX 280's running in 3-way SLI. This year I switched to Mac after 20 years of Windows. However, after 20 years of being a hardcore PC gamer, I accepted that my changeover would come with the price of having to maintain two systems: One that can play some games, and one that can play all games, and play them at the top of their performance potential. It will be my first Vista machine, and I enjoy the humor in the fact that it will never be used for anything other than playing games. (Anyone who understands what '20 years of hardcore PC gaming' means will know not to bother uttering the word, 'console'.)
I'm going to keep Googling around to see if I can find any evidence of someone running a previous gen MBP with this monitor. If it's a bust, I'll cross that bridge when I come to it. I may still switch back to a previous gen as I have a couple other issues with the new one, but either way, I'm still super happy that I've made the switch to OS X and I can't imagine ever going back.
Though I'll be making daily visits for things like this:

Help Connect my Mid-2009 Macbook Pro to my new YAMAKASI CATLEAP Q270 SE 27" LED 2560X1440 WQHD DVI-D Dual Computer Monitor

Hi,
I am trying to connect my Mid-2009 Macbook Pro to my new YAMAKASI CATLEAP Q270 SE 27" LED 2560X1440 WQHD DVI-D Dual Computer Monitor. I am not having a lot of luck.
My machine:
OS: Mac OS X Lion 10.7.4 (11E53)
Graphics Card: NVIDIA GeForce 9400M 256 MB
Processor: 2.53 GHz Intel Core 2 Duo
I am trying to connect it using the:
Mini DisplayPort to Dual-Link DVI Adapter
DVD-D HDMI cable
YAMAKASI CATLEAP Q270 SE 27" LED 2560X1440 WQHD DVI-D Dual
(http://www.ebay.com/itm/150788045871?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m149 7.l2649#ht_16597wt_877)
Here is what is happening.
1. I connect the Mini DisplayPort to Dual-Link DVI Adapter + HDMI Cable to Monitor
2. Main monitor powers up like it is trying to display
3. Laptop Monitor displays second part of desktop
4. I can never get the Yamakasi to display a picture
Here is what I have tried:
1. Different HDMI-D cables
2. ATLONA AT-DP400 Dual Link DVI to Mini Display Port Converter
3. Zapping the P-Ram
4. Powering monitor with laptop closed
5. Forcing the system to see the second monitor
The nearest I can figure:
- The laptop does see the catsleap (it displays resolutions I can set it to)
I am completely stumped, I was hoping someone could advise me.
Thanks,
Don

Hey Kytarx,
I found the winning combination this weekend.
I tried:
- Apple Mini DisplayPort to Dual-Link DVI Adapter
- ATLONA AT-DP400 Dual Link DVI to Mini Display Port Converter
- Monoprice Mini DisplayPort | Thunderbolt® to HDMI®, DVI & DisplayPort Adapter
My experience:
- Altona didn't work at all, and their support claimed it would not.
- Monoprice didn't work to Dual DVI, it did work to HDMI (great price I wish it did)
- Apple Mini Displayport adapter did work, but would only work with certain USB + Display port combos.
The thing that was tripping me up was that two of the Dual DVI-D cords were bad. Once I found the working cord, it was easier to find the working adapter. The experience I did find to be a frustrating / expensive one. However, the Monitor itself is beautiful.
Hopefully this helps someone else..

I have set up a Netgear dual band modem which works well with the iPhone and an older MacBook, but with this brand new MacBook it asks for a password every time I reopen the computer and open safari. Is it Lion?

I have set up a Netgear dual band modem which works well with the iPhone and an older MacBook, but with this brand new MacBook it asks for a password every time I reopen the computer and open safari. As you can imagine this is very annoying. It says I am not connected to the internet and offers me a choice of nearby networks including mine and then asks for a password when I select it. Why does it do this with our new MacBooks (also with my son's brand new one) and not with the iPhone, iPad and older MacBook? They happily automatically connect to our network after entering the password just the once.

Sig, I appreciate you trying to be helpful. I have no idea what issues you were having or what issue exactly pgrounds has been having. Your assumption that everyone's set up is the same as yours is false however. There are many many documented WiFi issues that are a result of Lion installs. Many have been solved by 10.7.1 and 10.7.2. Others have been solved by a large variety of work arounds. Others have not had their issues solved yet.
I am one of those. I have an IT background, and I spent the better of five hours digging up workarounds and attempting all of them. For the benefit oh anyone who is having similar issues, I have posted links to all of those workarounds here. None of them worked in my case, but hopefully they will help pgrounds or others.
So, once again, if you have a new idea, I'd love to here it. But if it has already been posted in one of these links, it's not helpful, let it go.

Normally, you just connect the monitor to the MacBook using a VGA adaptor that you can buy from an Apple Store. Now try System Preferences > Displays > Detect Displays. You should now be able to select a display mode for the monitor. If it still doesn't work, then I'd check that everything is properly connected. I've had problems with colours disappearing due to a faulty connection in the VGA adaptor.

New Dual Monitor Setup; iMac 21.5

I finally have my new dual monitor set up for my iMac after asking a while back.
I ended up getting a Lenovo monitor because thats the best deal they had. It matches pretty good, seems a little cheap but it works and works well for what I am going to be using it for.
The colors are a little off and yellowish but I am going to wait to give any kind of a review until its used for a month or so. That will give it some time to "break in".
Enjoy

Hi BNun
It is real easy to select different Profiles and/or create new Color Profiles for your Displays.
Just go to: Apple > System Preferences > Displays > select the Color tab on the display preference panel for Lenovo display and uncheck the box " ☐ Show profiles for this display only" then
1. Select a different profile such as (Adobe RGB, Generic RGB, iMac, etc.)
2. Calibrate and save a custom Profile to the list. > http://www.computer-darkroom.com/colorsync-display/colorsync_1.htm
3. Sweet use any profile in the list, if you don't like it then switch back or create another.
In my case I could be happy with using the Generic RGB Profile and then lowering the brightness a notch or two, but prefer to use (W2253 Calibrated 3) which was my third attempt of 5 creating some new profiles for my LG.

HT1338 I just bought a brand new mac mini, and finally got it authorized for itunes. I purchased some tv programs and now it is telling me I canʻt play them because my monitor doesnʻt support HDCP... I am using a 30inch mac monitor...

Any ideas how to get this working? I donʻt have money to go buy a new monitor...

Unfortunately HDCP is a technical requirement for the playback of some movie formats, for example Blu-ray. If your monitor does offer this, make sure your cabling and connection type also supports it. If your monitor doesn't offer this, I'm afraid you may have to consider buying a new or additional monitor. Any other suggestions I could make are not permitted on this forum, I'm afraid.
I have this problem too. I have a 2005/2006 Apple Cinema Display that's still in perfect working order, but doesn't have support HDCP. I had to find an alternative way of playing back my blu-rays.

Old Apple Monitor, Brand New Mac Pro

I just bought a new 8-core Mac Pro but my old Apple 17" CRT won't connect to it. I was planning to use the DVI connector (just like I did on my old G4), but it seems that the connections on the new video card have gotten smaller.
My new Mac has the ATI 1900XT video card.
Is there an adapter I can buy from old DVI to new DVI? Please help, I've been itching to play with my new Mac!
I am planning on getting a new Apple LCD monitor, but I can't afford it at the moment (because of the new Mac Pro).

Photoshop CS3 allows me to enable Open GL but CS4 does not Brand new MacPro with ATI 4870 card

Hi,
I just bought a brand new 8 core Mac Pro and have both the ATI 4870 graphics card and the Nvidia GT 120 card. Pshop CS3 allows me to "enable openGL" in the prefs and utiizes it when doing 3d stuff... however, CS4 has it dimmed in the prefs, thereby not allowing me to check it (it is dimmed and unchecked I should say) and when I do 3d stuff a dialog box saying
"Your video card does not meet the requirements for hardware-accelerated 3D rendering. All 3D will be rendered with software only."
any thoughts?
thanks in advance.

yeah, short term test deems keeping both cards in.
So, here are the results: Notes: I have 2 monitors, an Apple 30" and Apple 23". The 30" can only be used in the dual link dvi port and NOT the Mini Display port. Second: The ATI 4870 seems to have an issue with the Mini Display port, it does not work, alone or in tandem with the dual link dvi port being used. Apple is replacing the card (heretofore, I had no cause to use the Mini Display port on the 4870 at all) Third: Only Photoshop CS4 extended was used to see if the card was detected and if it had enabled Open GL
ATI 4870 - dual link used, Mini Display NOT used: Photoshop sees the card and enables Open GL
ATI 4870 - dual link used, MIni Display used: didn't test because Mini Display port did not work.
ATI 4870 - dual link NOT used, Mini Display used: didn't test because Mini Display port did not work
Nvidia GT120 - dual link used, Mini Display NOT used: Photoshop sees the card and enables Open GL
Nvidia GT120 - dual link used, Mini Display used: Photoshop does not see the card and thus Open GL is NOT enabled.
Nvidia GT120 - dual link NOT used, Mini Display used: Photoshop does see the card and Open GL is enabled
ATI 4870 Dual link used, Nvidia GT120 Mini Display used: Photoshop does not see a card and Open GL is NOT enabled.
ATI 4870 Mini Display used, Nvidia GT120 dual link used: did not test because ATI Mini Display port did not work

Brand new iMac freezes constantly! Updates aren't helping!

Hello everyone,
This past Sunday I bought a brand new iMac intel Core 2 Duo with a 250 GB HDD and 1 GB of RAM. At home I set it up with my SAMSUNG 1080p 22" monitor, Apple bluetooth Keyboard and mightymouse, and a Western Digital 350 GB HDD hooked up via USB. I was excited to finally jump on the intel-based Mac bandwagon, as well as experience dual monitors for the first time.
That was Sunday. Tuesday evening I was watching "Rome" on itunes on my Samsung monitor while surfing the web with Omniweb on the iMac monitor. All of sudden, everything locked up. I was able to move my cursor, but nothing responeded to my clicking. I hard booted the system and loaded everything I had going again, and sure enough, it locked up a few moments later. I ran system update, updated everything, then restarted. Time went by and although not immediatly, later that night it froze up on me again.
Fast forward to last nite, and the freezing reached and all time high. 5 times. Each time was when I had a browser open in my iMac window and I had Quicktime playing in my Samsung monitor. I was watching a sports program, with the player fit to the screen.
I have read many posts about intel iMacs freezing late last year, but there was a firmware update that evidently fixed that. I have this update installed, and I have had no luck. I have even contacted Apple Care via phone where I got instructed to unplug everything, plug it back in, start in safe mode, and delete cache. That didn't help me out at all. Am I right insuspecting I have a faulty Video card? I just ordered 4GB of RAM, could this be a RAM issue?

When diagnostics are run on a freezing computer and nothing shows, I'll put the program into a testing loop because this means one of two things: the issue is heat related so running the diagnostics several more times will bring on the heat so that the issue shows up or the installed RAM is marginal, just flaky enough to show up now and again but not so far off that a run through of the memory test catches it on the first run.
As I said in my original post, memory is always a suspect in a freezing or kernel panicking computer. And it does tend to top my list. But from what you describe I'm not quite willing to say, "Why don't you just wait until the RAM upgrade arrives?"

Brand New 13" Macbook Pro Retina (Mid 2014) Overheating?

Last week I brought a new 13" Retina Macbook Pro. I am so excited and happy since I finally got my first Macbook after a long waiting and saving up money.
Everything was working so well so far, until recently I got bit concerned about the heat that this macbook generates. The first time I noticed this when I was watching a flash video. The back part of it was too hot, that I can't even keep it my lap. The next day I got the same issue. This time I installed Istat Menus to monitor the temperature, and it was 83 degree celsius.
I thought it was a flash player issue. Reinstalled, results same. Changed browser from Chrome to Firefox, same result. CPU usage was about 25 to 35% when running flash content and simple css3 loop animation.
Moved to Safari, temperature down to 47 degree celsius, CPU usage was 10 to 15% running same flash content and simple css3 loop animation.
So I guess It is the browser issue.
Now installed a brand new HP printer, Opened mac's default scanning window and scanned a document, there it was again, the temperature was 82 degree celsius, CPU usage was 25 to 30%
Now running vmware, same result, temperature 85 degree celsius, CPU usage 30 to 45%.
It is like whenever I use an app that takes more than 20 to 25 % of CPU, the temperature spikes to 80 degree celsius and above. I can't imagine what an app with 75 to 80% CPU usage would do to my Macbook.
I don't know if now a days , Macbooks are like this, Couple of people report here the same. All Mid 2014 Model.
https://discussions.apple.com/thread/6476065
https://discussions.apple.com/thread/6518207
https://discussions.apple.com/thread/6508083
My experience and knowledge is limited to PC usage, as far as I know a PC won't do this for a basic task like watching flash content, playing css3 loop animation.
Can somebody tell me what is going on?

HELP - Brand new computer build - stuck in FF - NO BIOS

Hi,
I have put together my very first PC build computer with ALL brand new hardware components. I'm newbie when it comes to putting a whole build together. I believe have connected all the necessary hardware components needed to the my new MSI 790FX-G70 motherboard and PSU (Ultra 750W). When a start up the machine I have power and motherboard and all fans worked. However, I'm not able to see the BIOS on the monitor. Nothing actually is shown just blinking monitor green light on my Samsung 17 inch. The motherboard reads only reads "FF" then in a few seconds the "FF" disappears for 1 second and the "HDD_LED" red light to flashs on the motherboard - this cycle just continues over and over.
So then I disconnected everything except for the motherboard, CPU, Graphics card, 8GB memory (along with the monitor, mouse & keyboard) Still getting same results - NO BIOS display - motherboard shows "FF" and then revs causing "FF" to disappear and the "HDD_LED" red light to flash on the motherboard.
Keep in mind, I have brand new components and no drivers or OS has been installed yet. What can be checked to ensure proper installation - even thought I followed the guide correctly. Is there anything that can be reset safely. I tried the reset button and nothing seemed to happen. I also swapped out the graphics card and tried again still no dice. Any suggestions would be appreciated. Thx.
