Macbook heats up using ext display

My macbook 2.16GHz is dimming so I plugged in an older LG display and put the MB into clamshell. I notice that the MB is getting pretty warm. Is this because the lid is closed. Not only is the screen dimming and so is my eyesight. I'm wondering if heating up is normal, or if the display is too old and a newer one would be cooler? I really like the big screen but can't afford and iMac.
Thanks,
Connie

I'm using a macbook with Snow Leopard but the closed lid option was clitchy. We are supposed to put the MB to sleep and then open the lid ant the MB display would stay off. Didn't always work. The MB had a heat problem which caused a Kernal Panic yesterday. Not receiving any replies from this question I began again searching for one. I did a search of these discussion boards and couldn't find the link below because the way Discussions now works it didn't show up. So, I searched Google. It found the link below. End of part one.
I discovered the magnet fix in the link below which is primarily used for Lion, but I wanted a simpler fix for Snow Leopard. What I discovered is that all you have to do is Pass the little magnes over the sweet spot and the MB display turns off. The magnet doesn't have to stay on the computer sweet spot.
This makes me happy because who likes the idea of a magnet on their Macbook?

How to charge mid 2011 macbook air battery using Thunderbolt display

While trying to organize all my computer miscellaneous (cords, adapters & so on), I came across an adapter on a little card with the comment, "For use with your Thunderbolt Display and Mac with MagSafe 2 port." Appears to be for charging my mid 2011 MacBook Air via the Thunderbolt Display -- what might be the advantages/disadvantages in doing so? I found the info. in the product manuals to be pretty skimpy about this.
Thanks,
Linda

So, I guess the adapter came with the display just in case I had a compatible Mac. I should have noted that on the card. Now, about the rest of the stuff in my Apple mystery box...that's for another day.
Thanks, seb101, for your quick reply!

Can MB deal with heat using ext. display with MB closed

I intend to buy a cinema display and keep my macbook closed while working.
Can the macbook handle the heat? Or do i need to use a laptopcooler? If so any advice on what to buy?
MacBook Mac OS X (10.4.7)

Hi.
That link is only for the PowerBook G4 and MacBook Pro.
It says on the MacBook's tech specs that it supports closed-lid operation, but I don't see how that's possible. The MacBook's air intake is the keyboard, so once the lid is closed there is no longer any way for cool air to pass through it. And, the MacBook goes to sleep when you close it. But, if the specs say it's possible, then I guess it is somehow.
It would be nice to know how to do this.

Close the macbook pro when using external display

Hi
I would like to know if is recomended to close the laptop when using an external display? i ask because i read somewhere that the system take ventilation through the keyboard? is better to work with the laptop always open? or doesn't matter if is closed?

Third opinion...
I had a 2.16GHz 15" MacBook Pro that I used as a presentation machine at some trade shows in '07 and I once ran the machine with the lid closed, hooked up to an overhead projector looping a movie for 11 hours. When I finally shut it down for the night the machine was pretty warm (it was well ventilated) and was immediately usable. Out of curiosity the next day I ran it with a lid slightly cracked and the unit was significantly warmer at the completion of my day.
The only thing I could justify as the temperature difference is that the LCD was on and causing heat in addition to the video card. I guess I would have been curious to leave the lid slightly cracked and then manually set the backlight to off.

MacBook Shutdown when using external display (DLP TV)

I have a latest gen. MacBook. I just purchased the new wireless keyboard and mouse so that I can use the computer with my HD TV with VGA input. The setup works fine in two screen mode (laptop display as well as TV). However I want to use it with the TV as the only display.
I close the laptop and wake it up via the bluetooth keyboard with the TV attached. The screen comes on as it should and works fine for 3-5 seconds. Then the computer goes back to sleep. I don't understand what's wrong. Perhaps the laptop is looking for some type of response back from the TV? The same thing works fine on my Dell monitor. The computer stays awake with the monitor as the only display and the wireless keyboard and mouse as the only inputs.
My TV is a 61" Samsung DLP with VGA input. I'm using the new apple wireless keyboard and mighty mouse.
Does anyone have a similar setup that they can try this on for me? Has anyone run into the same issues?
Thank you for your help.

One thing you've neglected to mention is whether you have the MacBook plugged into its AC adapter. The behavior you describe of the MB going right back to sleep is what happens if you try and do what your doing running from the MB battery. So check and make sure the AC adapter is connected and working.

Lost program display after using ext display

I am away from home and only have my MBPro. I home I have an external display and was running Google Earth on the external. Now I start the program and it is not showing on the laptop. Is there a command that will move the program to the active screen if you are not using an external diaplay?
Thanks for any help.

Go to System Preferences > Displays. Select a lower resolution than your current one, let the display switch, then return to your normal internal display resolution (1440x900 or 1680x1050 depending on whether you've got a 15" or 17"). This should do a complete refresh of the display and bring all windows back onto the internal display.

HDCP error on MacBook Air (NOT using external display)

I just downloaded a HD (720p) movie through iTunes, and cannot play it on my Mac becuase of a HDCP non-compliance error. I am running it directly on my MBA, not through an external display... I would have thought the MBA integrated display would be HDCP compliant! Is this an error or am I wrong in assuming my MBA could play legally purchased HD movies?

Try a System Management Control reset (SMC)
Whilst the machine is plugged into power, Hold down the left side shift control and option buttons at the same time as the power on button.
Hold these down for 4 seconds and relese all at the same time.
If this fails then you may need to clear the caches folder for your user too.

Having problems connecting a late 2011 Macbook Pro 2.2ghz i7 to a Sony KDL-32L5000 using a display miniport to DVI adapter (DVI to VGA cord). The TV is not detecting the macbook. Anyone have this problem?

You really have to mess with the resoluton, espescially the refresh rate, as it varies from projector to projector, monitor to monitor. Even within the same brand! Because so many manufacturers are trying so many different things to become the next cool kid on the block, and the way the formats are being configured that's now part of the game.
That's why so many professionally produced corporate shows hire a dedicated projectionist for the video presentations. Too many bugs in the honey.
Refresh & sesolution are the first things to look at.
Just so you know that colors in PowerPoint PC, and PowerPoint Mac, don't exactly match... go figure.
I forgot to mention another thing, sometimes it's the projector that needs to be tweaked.

I have a 17" Macbook pro with flickering red and cyan(blue) lines across the screen. The issue disappears temporarily when I tap on the computer, and the problem does not occur when I use external display or try to screen capture the problem.

I purchased my Macbook (17") through a certified apple tecnition in August 2012, it was refurbished and the motherboard was completely replaced. I do a lot of photo editing, but I have been unable to do so because of the red vibrating lines that interrupt my screen. The issue disappears temporarily when I tap on the computer, and the problem does not occur when I use external display or try to screen capture the problem. I brought the computer back to the technition I purchased it from and he said that it was a problem with my fan, so I have two new fans but the issue is still occuring. He says he doesnt know whats wrong. Does anyone have any information on this issue?
Here is an image of the issue

I recommend having your Mac serviced by someone competent. A force sufficient to "blow apart" the fans was clearly excessive and may have damaged the display cable, as well as any number of other problems.
Dust is properly cleaned with a vacuum, preferably one designed for computer service, and they are not cheap.
Compressed air should never be used. It just blows dust everywhere, often into places where it can no longer be removed.

MacBook suddenly won't detect my display, Using Mini Display Port to VGA?

MacBook suddenly won't detect my display, Using Mini Display Port to VGA?

dohdoh1985, I have the exact same problem also! I recently bought a 42" RCA LCD TV. I connected my MacBook Pro to my TV using a Dynex Mini DisplayPort to HDMI adapter that I got from BestBuy. It worked great until I upgraded to Mac OS 10.6.4 and then it suddenly stopped working. Same TV, same settings, same cables, same adapter. Nothing changed since the last time it worked except that my OS was upgraded to 10.6.4, so i am assuming that is the culprit. The symptoms are EXACTLY the same as what dohdoh1985 described; when I plug in the TV, the laptop display flashes (3 times) as though it is detecting an external display and the picture on the TV briefly goes from blue to black for about 1 second then back to blue. The TV does not appear in the display menu / control panel and there is no sign that the MacBook detected it. I went through the usual troubleshooting steps (reset PRAM, checked connections, tv settings, etc) but nothing worked. Other HDMI sources (i.e. Blu-ray player) work fine on the TV using the same HDMI cable on the same port so there is nothing wrong with the cable, the TV or the TV's input settings.
Meanwhile, I can still connect my MacBook to my external ViewSonic monitor at work without any problems. It's just the TV that's not working.
I cancelled my cable subscription a while ago since I only watch shows online nowadays and this was my only way of watching TV shows, so I'm quite upset.
Apple, please help!

Hello chrispyw,
If your content is still being displayed incorrectly, I would check the resolution setting for the built in display with this article:
OS X Yosemite: Adjust your display’s resolution
If it keeps happening whenever you use AirPlay then I would use this section of the following article to reset the display system:
Apple computers: Troubleshooting issues with video on internal or external displays
Reset the system
You can reset the Mac's parameter RAM and SMC.Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
Thank you for using Apple Support Communities.

Sterling

Can the Macbook Air be used as a display monitor for Xbox 360 ???

Hi Guys,
Basically I was just wondering if the Macbook Air 11'' can be used a display monitor for the Xbox 360 due to me smashing my TV... Ooops.

Many Thanks,

Heat problem with multiple display (retina Macbook)

Hello.
I'm using retina Macbook pro 15".
It is totally fine when i'm using macbook by itself.
However, the temperature and fan speed increase whenever I plug in displays.
If I use just one display, the change is not noticeable, but if i plug another display, GPU die temperature goes up to 75 degree C and fan speed become 3000rpm (from istat dashboard).
If I use 3 displays (one thunderbolt, one hdmi and one with hdmi to mini dp), fan runs around 4000rpm which is quite annoying.
Of course, above testings are all done in idle state.
Is it normal or need to be fixed?

this is normal. When connecting more monitors, the GPU has to render more pixels, thus making it work harder, driving up the temps and triggering the fans to blow more air.

How do you use multiple displays with a MacBook Pro and iMac

I have an iMac and a MacbookPro laptop both upgraded to OS X 10.9 (Mavericks). I'd like to use multiple displays with them. Can I do this without an Apple TV? They are both on the same network. If I can, can someone please give some instructions on how this can be done?
Thanks!

Both computers have ports for external monitors. Check your user manuals. Only one display can be added to the MBP, but newer iMacs have dual Thunderbolt ports.
Do your own Google research to learn what to do, but reading your manuals should be all you really need. It' not rocket science yet.
