External screen with macbook pro blinking

Hi everyone,
i've an external screen ACER connected via hdmi to my macbook pro run on Mac OS X Lion 10.7.3
The problem is the external screen blinks every 3 or 4 minutes, i get a dark screen for 1 or 2 secondes
i tried to change both the cable and the adaptater [hdmi] but it seems that the problem come from the OS configuration.
When i open the console.app to see which are the errors i got
IOSurface: buffer allocation size is zero
every 2 or 3 minutes, i need your help please

I own a mac mini that stays connected to the 52" LCD 120hz in my living room. The image is perfect, and fits just fine. I did a mini-display port to dvi and got a monster cable adapter for dvi to hdmi which too it to my tv. I did have to go into the tv and set the tv to overscan I think on the image to make it fit and you will have to adjust the resolution on the computer. I can say the colors are darker on the tv and this is just due to the nature of the screen size. Newer LED tvs may be better, but mine is only 1 1/2 years old.
For an external display, just go to the educators link, select your college and you get $100 off. My wife is an educator and I am back in college so it's no hassle. Or they just ask for an ID. I own 2 24" ACD and they are nice. I do photography and a screen calibration is a must. Once done you'll be happy. And docking with the laptop is handy.

External Speakerphone with MacBook Pro?

Hi All,
I'm really liking iChat with my Macbook Pro with internal iSight. But, the audio is good, but not good enough for serious applications and I don't really want to use a headset. I'd like to get more audio volume and have a more sensitive microphone, handsfree.
Is there such a beast as an external "speakerphone" mic/speaker combo that could be used to sit on the desk either wired or bluetooth that can interface with iChat?
Thanks,
Paul

External display with MacBook Pro in Lion

Hello,
Yesterday I bought a Mac OS X Lion, and I found one annoying feature of the system - working on a MacBook Pro (MBP), and very often use an external display, with that do not use display in the MBP. When connecting an external monitor doing video processing,and this activity I was used by Mac OS X Snow Leopard to open the MBP there wasaccess of air to cool the computer. After installing the Lion was the fact that even at very small opening MBP is switched to internal MBP display. This is the functionality of the Lion off somewhere or somehow set? I looked in Preferences, and I have found nothing. Thank you in advance for information on how to solve this problem.

Can't detect some external displays with Macbook Pro 17"

My macbook pro 17" connects just fine to my Apple Cinema display. But twice now I've tried to use it for presentations where I am connecting to either a video projector or a plasma screen through some sort of switchbox installed in the room. There's a VGA cable I'm supposed to connect to, and I use my DVI-VGA adaptor for that. But the macbook never recognizes the external monitor. In one case, everytime I hit "detect displays" i would see a brief bit of noise on the external screen like it was about to connect, but then nothing -- and Display Preferences showed no evidence of any connected external monitor. In both cases, I know the host systems generally handle Macs just fine. Is there something different about a Macbook Pro with dual-DVI? A design flaw or a mysterious switch that needs to be set right? Or maybe there's a glitch in my specific macbook??

External display with MacBook Pro.

What is a good external display to use with the MacBook Pro? I hooked it up to my TV (Samsung HD) and it did not look great. Is there any other option aside from the DVI (or whatever it is called) to VGA to get better quality?
I do photography and want to have a display running as I shoot at trade shows. I know a apple display would be great, but I would just get an iMac instead.
Thoughts welcome,
Todd.

Trouble using external iSight with MacBook Pro (which has built in camera)

Hey Jim,
Have a question for you. I have a new MacBook Pro 17". I also have a 23" Cinema Display, and a left over Firewire external iSight camera (which I used to love).
Frequently I "dock" my MBP with my 23". I either use the dual-screen between the two, or I close the lid on the MBP, let it go to sleep, then wake it back up with a BT keyboard or mouse, letting it go to a single-screen mode on only the 23" Cinema Display.
So, I'm trying to use my external Firewire iSight with my MBP, and I'm getting mixed results -- the best of which is where I am getting some video with regular, occasional freezes with the picture being split (like a v-hold problem on an old TV). After a pause it goes back to smooth video.
I guess primarily, I'm wanting to know what the world of two iSights (FW and built-in) look like, and can they work together? I cannot for the life of me get this FW iSight to work consistently, but I know it works perfectly in another G5 tower (which has no built-in camera).
Any suggestions or guidance?

Hello Exivus
... two iSights (FW and built-in) ... can they work together?
You can have two iSights connected at one time, but, as explained in Apple's iSight "Your camera is in use by another application" message, iSight can be used by only one application at a time. (my emphasis)
Different apps select between multiple connected cameras in different ways. For instance, iChat > Preferences... > Video settings can select which camera to use with the iChat app, but iMovie 6 uses a drop-down menu as shown in this picture:
The suggestions in How to Troubleshoot iSight should help you determine whether one of your iSights is causing trouble. I suggest you test each one separately and without your external display or other peripherals to rule out possible conflicts.
After you are certain that your iSights are working individually, test them when both are connected. After your system successfully passes these tests, you can add your external devices back one-by-one to be sure one of them is not causing the problem.

Using External iSight with MacBook Pro / iMac.

Posted in both forums.
Internal iSight is great, but the external iSight offers so much more flexability, and been able to position the camera where you want it is much better than tilting the screen and moving the computer.
So can you use external camera's with the MacBook Pro's and iMac's?
*nathan

Great! Thats awesome.
Have you tried it? If so, does the Mac automaticlly switch to the external iSight, or do you get an option to choose between internal and external.
Thanks,

Cannot use external Display with MacBook Pro 13

3 Screens with MacBook Pro 13' ? or just with the 15'

is it possible to connect 3 screens (no Thunderbold) with the MacBook Pro 13' Retina (early 2013) or only with the 15' Retina with the external graphics card.

Hi,
It really depends on what you'll be using the MacBook Pro for.
If you're selling your iMac, will your MacBook Pro be a desktop replacement? If so, I would go down the 15" i5/i7 route, but that's based on HD encoding requirements I currently do on my iMac.
As it is, I recently sold a 2008 unibody 15" 2.53GHz as I found it too large to comfortably carry around. I was thinking iPad, but decided a 13" MacBook Pro was the best of both worlds, a fairly capable mobile offering, physically smaller than my old 15" unibody yet more powerful than an iPad.
The 13" reminds me of my original PowerBook G4 12", which was my prefect travel companion (computer wise).

After upgrading to Yosemite, I am unable to share screen with Macbook Pro

After upgrading to Yosemite 10.10 on a 2008 MacBook Pro I am unable to "Share Screen" using my authorized user account. It worked fine before I upgraded to Yosemite.
I can access "Share Screen" by "requesting permission", but of course this doesn't work unless I am sitting right by the MacBook Pro to give myself permission, which defeats my original purpose for using "Share Screen".
I attempted to add another authorized "Share Screen" user account, but was unable to access the list of add "Groups and Users" on the host MacBook Pro from the "Share Screen" dialog box. The dialog box pops up, when I press "+" to add another user, but the list of users fails to appear. I assume the list of authorized users for screen share has somehow become corrupt.
All other ways to access "sharing user" accounts appear to be working properly. I can add and remove other "sharing users" without problems. For example, I can add a new authorized "file share" user and share files without problems.
I ran Disk Utility in Recovery Mode and normal mode and corrected all errors, and user permissions on both machines. I also ran "resetpassword" from Terminal in Recovery Mode and "reset" user permissions. I am not an experienced Terminal or Recovery Mode user though.
I also tried turning the Firewall off, to no avail.
I am attempting to access "Screen Share" on the MacBook Pro via a Macbook Air 13" manufactured mid 2013 also with Yosemite 10.10, however, I also attempted with an older MacBook Air which experiences the same problem.

Thanks for the idea but it did not work, I do not know why it is asking me for a password which I never needed before for a guest to use the computer? I have tried everything and I do not know which password it wants? I do not see any option for a password for the guest account, to create one or delete one or modify it? Maybe this bug\problem will be addressed in a future update?

External monitor with MacBook Pro

I have a new Macbook Pro and have it hooked up to an external monitor and an USB Apple keyboard in my home office. How am I able to power the laptop on without opening the display and have it display only on my external display? When I am at home I'd like to use my external monitor and not my Macbook display.

Having the computer with the lid closed is dangerous cause even when just browsing the web with flash content it starts heating up and I've heard about casess of melted displays. Besides, the wifi strength is reduced and you can't use the keyboard and the trackpad.
So, for Lion users, it's possible to just use the external display with the lid open:
1. In Mission Control Preferences activate one Hot Corner to put the display to sleep.
2. Connect the external monitor and plug in the power source to your computer.
3. Move the mouse to the Hot Corner to put the display to sleep.
4. Close the lid and wait a few seconds.
5. Open the lid and voila!
Take care!

Can I use Front Row on external monitor with MacBook Pro's cover closed?

I've seen that you can use the remote to control Front Row even when the lapatop's cover is closed (on a MacBook Air). Is it possible with a first generation MB Pro? Are there special settings?
Thx

You can use a MacBook Pro in "clamshell" mode if you have the AC adapter plugged in for power, an external display attached and an external keyboard and mouse (USB or Bluetooth) to wake the computer after it's been closed. This is the official word from Apple:
http://support.apple.com/kb/HT3131
However, even if you don't have a keyboard and mouse, you should still be able to wake the MacBook Pro using the Apple remote by pressing the "menu" button. (You do still need to have the power plugged in and the display plugged in.)

Using external iSight with MacBook Pro crashes iChat

I use my Macbook Pro in clamshell mode with an external display. I bought an external iSight so that I could use iChat AV. I have the appropriate adapter to convert the Firewire 400 cable to Firewire 800 which is compatible with my '09 MBP 17" (2.8GHz).
Every time I connect the iSight, iChat will launch, and then will crash (SPWoD). I can not recover unless I disconnect the iSight, at which point iChat is able to fully launch.
I tired changing both iChat and Photobooth to 32-bit mode (hint from another thread), but that did not help.
As a test, I connected the iSight to an iMac with both FW400 and FW800 and the iSight works perfectly with either connection. iChat AV then allows me to then select which camera I want to use in its preferences.
Both my Macbook Pro and the iMac are on OS X 10.6.2. iChat crashes regardless of if I am using the MacBook Pro in clamshell mode or not.
TIA.

Thanks for that info, bryanus
Between this info and your latest response to Ralph, there are so many possibilities that I cannot yet identify the source of your problem. More troubleshooting is needed to identify the cause so we know what to fix.
Your used iSight may be causing the problem. Because it is easiest to troubleshoot, I suggest you test the external iSight next. The following will either eliminate your external iSight as the cause of your problem or let you know whether it will require professional service.
If the testing I suggest below shows that the problem is related to iChat ONLY, stop the testing I suggest and follow Ralph's expert suggestions for troubleshooting and correcting iChat.
Don't worry about the "clamshell mode" issues at this time. Until you get your external iSight working reliably with your MBP, keep the external display disconnected.
Additionally, to eliminate possible network problems as a contributor to your problem, when testing (internet) connected apps like iChat, use the same ethernet connection when you test both Macs. Even use the same ethernet cable (no wireless) connection to all Macs.
Also, to test problems with launching iChat, _disconnect both Macs from the network_ to see if iChat will launch properly with a connected external iSight but no internet or network connection.
You have already done some excellent testing, but you can use the additional suggestions from the following link (including other subject links on that page) to test the remaining user-correctable possibilities:
http://www.ralphjohns.co.uk/EZJim/EZJimpage4.html
Pay particular attention to *possible conflicts*, testing with more than one cable and/or adapter, and testing the external iSight on more than one Mac. If possible, it would be also good to use your same cable and FW Adapter to test your MBP's function with a different and known-good external iSight. If you have no other access to a working external iSight, your local Apple-Authorized Service Provider may be have one that he can use to check your MBP connection.
If your external iSight can connect reliably to other Macs, or if a different, known-working, external iSight also gives trouble on your MBP, the problem must be either in your MBP's physical Firewire connection port or in the software on your MBP.
Unless you find a fix while trying the above, we can offer suggestions for the particular problem(s) you identify based on your troubleshooting, so give as much detail as you can about your findings when you post back.

Using external mouse with Macbook Pro

Hi,
I'm using an external Dell USB keyboard and mouse with my Macbook Pro. They work ok, but there seems to be a bit of 'drag' when I use the mouse. It's difficult to describe, but when I move the mouse slowly the pointer seems to drag, or slip...it's not matching the movement I'm making with the actual mouse. It's not so bad when I make bigger or faster movements, just when I'm using it slowly or precisely.
It's very distracting, and is even making my wrists ache.
Any idea how I can stop this happening - do I need to find a driver to fix the issue?
Thanks for reading.

Are you using an external monitor? The 24" LED Cinema Display?
I saw a post in one of the other forums where several people were having this issue -- they all had external monitors attached, and mostly all 24" LED Apple Displays. The type and make of the mouse seemed to have no relevance, and the issues seem to impact the trackpad as well. It is hard to describe the "feel" and "lagging" effect of this problem.
Nearly all people in the post had the monitor and laptop power adapter plugged into the same outlet/powerstrip. After moving one of the cords to a different outlet, this seemed to solve the problem for nearly everyone. Odd, I know.
I'm gonna try it and I'll keep you posted.

Triple Screen with Macbook Pro 13" integrated graphics vs 15" dedicated graphics?

Am I gonna be able to run games with triple screen setups on the integrated Intel HD 3000 graphics or is it gonna be umplayable if I don't buy the 15" macbook pro AMD dedicated graphics?
The game I'll playing the most is world of warcraft, my future setup will be 3 screens of 19" each conected to the macbook pro with a resolution of 1400X900 each, using the matrox adapter.
I cannot buy an imac because i need the laptop for the university and programing outside the house

If you plan on doing any gaming, get a discrete GPU. An on-board likely will give you less-that-satisfactory performance.
