Macbook External Screen Mirror?

Hey guys,
I finally have everything I need to coonect my Sony 40" 1080p television to the macbook. I have a mini-dvi to dvi adapter and a dvi to hdmi cable. I was seeing how it works and when I turn on mirror mode for the display I can see everything that is on the macbook's screen with all the apps open and everything, but when I use mirror mode it does not seem like it is at full resolution. Even though it clearly states 1920x1080. Then, when i get out of mirror mode, it looks picture perfect, but I don't know how to run any apps and I don't see the icons on my desktop. The top apple bar is not their either. All I can see is my blue mac background, even though there are a few programs open on the mac. How can I fix this? Am I doing something wrong? Please help. Thanks

you need to have an external keyboard ,mouse and the power pack connected with the lid closed for it to work as the single screen or replacement screen.
you can also unselect mirror mode and have it as an extended screen. to get anything on it just drag an open window over the side of your macbooks display it should move over to your other screen.
you can set which side in system prefs

Macbook Pro with external screen

Hello guys!
First my setup:
Macbook Pro 2011 13" Low-spec.
Acer 24" FullHD external screen.
Apple keyboard.
Wireless mouse.
Now what i want to do with this is, i want to have my macbooks lid open, but the screen shut off, so i can use the great resolution of my Acer screen.
What i've been trying:
Have both open at same time in mirroring mode - MBP's resolution is "default" but my Acer screen turns to a REALLY REALLY bad resolution. Even though it's still set to it's default as 720p it's really bad. Now if i turn it to another resolution on my acer screen, it's just still bad.
Because of that, i've been trying to close the lid - This gives me a really great resolution on my Acer screen, and it's all sharp and nice. But as soon as i open the lid of my macbook pro, it goes back to the really bad resolution. Now you may wonder why i can't use it with the lid close - Because i want to use the inbuilt microphone for "Ventrillo" maybe the trackpad too, and being able to use the webcam too would be perfect.
So the question is: How do i turn the screen of my macbook of, so my Acer screen can have it's great resolution, and still be able to take advantage of the macbooks inbuilt luxury stuff.
Any help would be highly appreciated.
Over and out.

You don't have to turn off the built-in display to use the Acer at its maximum resolution. Just turn off Mirroring in Displays Preferences, and you can set each display's resolution independently of the other. In Mirrored mode, both displays always operate at exactly the same resolution.

Can you WIRELESSLY connect a macbook pro to a monitor to have extra work space on a separate screen from your macbook? (not mirror, extra monitor/workspace)

It needs to be wireless.
I am not asking about mirroring, but as a second screen.
Apple tv communties said the Apple tv cannot do this, but maybe another type device can?

My thunderbolt port stopped working on my late 2011 MacBook Pro rendering my external monitor useless--or so I thought.
Mac Genius suggested using the Apple TV via AirPlay Display as a $100 solution. Took me all of 6 minutes to figure this out as there are no directions in the Apple TV box supporting this. But, it does work and I am now back in business.
PS. Don't set up with bluetooth--seems logical but you want to use AirPlay Display under Settings > Displays.
Also, I originally thought my external monitor stopped working because I upgraded the OS. This time, it was definitely a hardware issue and not software. It also fixed a known sound issue my monitor had with Macs. First time in my 15 years I've ever had a ViewSonic have issues with an Apple product, too. Thanfully, it is now fixed.
Hope this helps.

Macbook Pro: both external screens go off when unplugging power cord

Hello!
I have my Macbook Pro set up with two external screens one connected thru HDMI and the other with Thunderbolt, I keep the lid always closed. I always have the power cord plugged in but when I for whatever reason unplug the cord both screens go dark and don't seem to "wake up" anymore. When I plug back in the cord I have to open the lid first to make the login window appear but after login my screens are switched. When I close the lid again it goes back to my original set up. The same when I turn on the Macbook and don't close the lid after it right away, the screens are switched until I close it.
Any idea on this?

As this article points out, there are very stringent requirements for using a MacBook in "closed clamshell" mode. #1 is to have the power adapter plugged in:

Connecting HP 2311x display to new macbook pro Retina - no output on external screen

I have a brand new MacBook Pro 15 in. with Retina display. I also have a HP 2311x monitor. When I plug in the HDMI cable, the external monitor says "check video cable" and the preferences "arrangement" thinks there is a display - even recognizes the type - but the external display just wont display anything but the "check video cable" box. I spent 2 hours on with apple yesterday, they had me do all sorts of resets and stuff - but no luck. The HDMi cable works when connecting a pc to the screen. When connected to by macbook, the screen on the macbook likes to flash black and its annoying. I have gotten really used to working with two screens.... and apple's suggestion was to buy a thunderbolt cable and try that. As it is, with this new macbook I have to buy a bunch of cables, I really don't want to buy another one when I am not sure that will work. Darn things are expensive when you are buying 4 connectors at once (ethernet connector since the speed via wireless is noticably slower; magsafe to magsafe2 converter; thunderbolt for my printer; and a connector for the monitor at home which doesn't have an hdmi port).
Any other suggestions before adding another to that list? Since Apple seems to be out of ideas... any info would be appreciated.

I have an HP 2311x as well. I'm using an HDMI cable and am not having any issues getting the screen to display. I know you said the cable works with a PC but have you tried a different HDMI cable just in case. It might be worth a try. Other than that, I'm not much help.
The issue I had when plugging this monitor into my MBP retina was that the image was very blurry on the HP 2311x. I almost gave up on using it and was going to just buy a Thunderbolt display but after much research I found a custom firmware update that fixed the underscan/blurriness issue. So be prepared for that if you get the screen to display.
If I can find that resource, I will post it here.
Good luck!

Going berserk - my Macbook Air shows irrational, whimsical behavior when it comes to detecting external screens - solutions?

My Macbook Air (OSX 10.9.1 - 1.7 / i5 ) is normally connected via HDMI to a LG 22EAA53 LED IPS monitor. If the combination is working properly, the motto is: don't pull any cables, don't mess with it. If I do pull the HDMI-cable, or, even worse, if I pick up the notebook and connect it elsewhere to a TV monitor for the occasional viewing of a movie (Sony-flatscreen), everything goes wrong. First because the Air may or may not detect the tv: sometimes he does, sometimes he doesn't. In the latter case it doesn't matter what I try: cables in and out, notebook on and off, ditto tv etc etc. Nothing will help change the Air's mood. Too bad, but hey, it's only a movie, and as long as I can work. Not so. When I (****** off already) return to my office and reconnect the air via the LG monitor, this now doesn't work either. The monitor says it gets no signal, and if I then pull the HDMI cable, I get the message that the connection is lost. In the Air-menu settings/displays the option to detect a external screen is non-existent. The only thing I can do, I know this from experience, is simply wait. Because within a couple of days the Air can all by itself decide to recognize the external screen again. I can't help but wondering about this whimsical behaviour. It makes you wonder if, in this era of state of the art technology, we made really that much progress compared to the people who lived thousands of years ago, who in case of problems had no other option than to wait for redemption by a mysterious, unknowable supreme being. And it appears I am not the only one with this kind of problem either – I found it on several fora, but alas, to no avail, the problem is common and recognized, a solution is not around, or so it appears. But maybe, maybe someone here has a bright idea?

The key to managing the single USB port on the machine is using as little wired hardware peripherals as possible. Here's how I have my setup (this was a similar setup prior to the Air):
1. AirPort Extreme Base Station that serves as my router
2. AirPort Express Base Station that serves as my speaker system (1)
3. AirPort Express Base Station that serves as my printer server (2)
I have a 320GB USB 2.0 HD that plugs into my Extreme, that I then backup to a secondary 500GB (monthly). The 320GB is split partitioned with 80GB serving as my machine's TM backup and the remaining serving as general file storage. On the general file storage I have my iTunes Library & iPhoto Library that are shared to three computers on my at-home network. I have a Mac Mini that serves as my "server" which runs OS X 10.5 server and facilitates any additional services.
As my entire apartment is "wireless" I can go anywhere in the place and have access to my music, files and printing without ever having to connect at any time. I use a bluetooth mouse and keyboard if I'm ever at my desk with the MBA and have a "setup" that I made with a monitor, stand, micro-DVI to VGA adapter and constant power available. I then have a USB extension cable that extends around the back of my day into a small "enclosure" I made on my desk that allows me to connect any USB peripheral such as my card reader, Super Drive, iPhone or iPod.
It's a fairly intricate setup that took patience, some design and planning but it allows me to use my machine as a true portable but with the flexibility to "dock" it when the time comes.

MacBook Pro retina and external screens

I connect my recently arrived 15" MacBook Pro retina to one of three 24inch Led displays which I use at different work locations... On two occasions on start up the external screen did not turn on. Power is on, USB not, led display is off, System preferences Displays module finds it... but there's not way to turn the screen on. Next day the very same screen turned on without anything particular being changed. Today I've not been able to turn on another of these screens, yesterday the third screen functioned beautifully more than 12 hrs.
Any suggestions about why this may be happening?
Thank you

Eventually I got so annoyed I tried going back to a time machine backup when everything was still fine. (restoring Mac OSX to a time when the issue occured did not help). That worked, however it would be nice to know how to reset the display settings without losing progress.

External screen doesn't go into standby when putting MacBook Pro into sleep

I'm using a new MacBook Pro with an external monitor (DELL P2411H) through a Mini Displayport to DVI adapter.
When putting the Macbook into sleepmode, the external screen goes into standby but immediately wakes up, then goes back into standby and wakes up ... this cycle doesn't stop. The only option is to manually push the powerbutton on the display.
I'm having this issue too when using a MacBook Pro 13", so it's not a single issue.

I got similar Problem, my external monitor will go to standby mode and then switch on immediately, and the go to sleep , and the monitor will show no signal detect

Can I screen mirror on a Macbook Air version 10.10.3?

I've just bought a Macbook air running OS X Yosemite and i have been told that they can screen mirror without any wires or apple tv, but I don't have a clue how to get it going.
please help

Sure, here's the solution:
The "Share" button was introduced with Mountain Lion! You should buy the Mountain Lion upgrade if your MacBook Air can handle it.

Macbook Pro w/Retina - External Screen

Hi,
My Macbook Pro w/Retina overheats like crazy. It nearly get sup to 100 degrees celcius while gaming or even watching youtube. So on the thought of overheating, is it because its using a lot of power to support the Retina Display sceen? What if I hooked it up to an external screen and shut off the main Retina Screen? (Close the macbook while running on external monitor).
Thanks,
Alfrancis Guerrero

In Windows 8 use the help menu and search for external display.

External screen problems with macbook pro

Hi Guys,
I have recently connected my macbook pro to an external screen via HDMI and am having a weird issue. When the MB is open, it perfectly displays on the external screen. But when I shut the MB, it displays the picture on the external screen for about 5 seconds, then turns off, then turns on again and continues this until I open the MB again.
WHat is going on? Am i missing something?
thanks guys in advance

Something that's running on your machine (or something that's connected to it) is preventing it from sleeping when you close its built-in display. It should sleep and stay asleep as soon as that display is closed, unless you are running it in clamshell mode:

Does the computer sleep properly when you close its display if the external monitor is not connected to it? Does the monitor have a USB cable that connects to the computer, in addition to its video cable?

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 screen with no power on macbook

It's so ridiculous that I can't have just an external screen on my macbook without power connected. Any software/pkg that fixes this?

The price you pay for being portable. If you want the configurability of a desktop, get a desktop.
The power required to process the video would drain the battery so fast you wouldn't be happy either.
Apple has decided which scenario you get to complain about

Is there an app for video playback on external screen from ipad mini which avoids mirroring?

I want to play fullscreen video from ipad mini to external screens with a clean look and without without showing playback controls etc. I need to be able to play, pause, change the order of video tracks without affecting the external display as it's for playback of video backing tracks for a music show.
Does anybody know of any apps which do this? I'm looking at Portfolio for iPad at the moment which looks promising.

No.

Got HDCP problem on macbook pro screen not even external screen

I have rented a movie (HD) on itunes.
I download it and try to play it, then I have a popup saying that the movie can't be displayed on my screen because of some HDCP restriction.
I don't understand, I've got a mbp retina display, I just try to play the movie on the computer, I did not even plug an external screen.
I am running Mountain Lion 10.8.4, with itunes 11.
I think the most innaceptable is that I did not even have a warning that say that I can't rent the movie, or that I would not be able to read it on my mac.

High-bandwidth Digital Content Protection(HDCP; commonly, though incorrectly, referred to as High-Definition Copy(right) Protection) is a form of digital copy protectiondeveloped by Intel Corporation to prevent copying of digital audio and video content as it travels across connections. Types of connections include DisplayPort (DP),Digital Visual Interface (DVI), and High-Definition Multimedia Interface (HDMI), as well as less popular, or now defunct, protocols like Gigabit Video Interface(GVIF) and Unified Display Interface(UDI).
Meaning, someone doesn't want you to be able to play the movie on the screen because of copyright reasons.
Sorry. (I know, DRM sukcs!!)
