Macbook + External Monitor + HD Video = 89 (C) Degrees

Mid 2008 Macbook, 2.4ghz, 4 gig ram,
BenQ 1920x1080 monitor via DVI
How concerned should I be with such a high temperature? The CPU has peaked at 89 degrees but it runs consistently hotter (65-70) on the external monitor.

Hi, Amanda.
I am guessing you are receiving a message: "This movie cannot be played because a display that is not authorized to play protected movies is connected." To view HD video on an external display, the display must have a digital connection (DVI, DisplayPort, or HDMI) and also support HDCP. If the monitor is HDCP compliant, then the issue would be related to the connect between the Mac and the monitor. I would recommend trying with one of the approved digital connectors.

Macbook, External Monitor (TV) and Windows

I have been trying (for ages) to get Windows to display on the TV. I can do it on the Mac side, with a DVI connector, but Windows doesn't work. No that I have upgraded to Leopard, I had hopes. Is there some setting I need to make this work? The Macbook says it is using Intel Mobile adapter.
When the DVI is hooked up in Windows my screen flashes. The external monitor 2 will not accept that it is there.
Thanks

As far as I know, Apple only sells one kind of DVI connector for around $20. Based on your statement about inputs to your TV, you should get an Apple Mini DVI-->DVI cable. Then, you'll need a DVI to HDMI cable to plug into your TV. I don't know your setup, but you probably should get one that is 6' unless you need a longer one.
You will also need a separate audio cable with jacks at each end similar to the kind that fit into your headphone out from your MB. In order to get sound, you will need a audio input that is tied in with your HDMI input. I don't know if your set has this setup. I have a Sony with 3 HDMI inputs, but only one of them has a separate audio input jack. If you don't have this audio input jack, you can run your audio to a separate stereo amp. Or you can go with the Component option which will definitely have an audio input.

Using external monitor for video editing.

Hello all,
I own a IMAC that I use for video editing on FC7. I was wondering via Thunderbolt to VGA (or any other way) if there was a way to use an external moniter as my canvus and the internal comands to do so. Also the opinons of doing this. Good? Bad? any good ideas?
Thanks.

Eeewww! Oh, the horror of what you are trying to suggest!
No. A video signal for a computer display and a video signal intended for TV are very very different things. If you want to PROPERLY see what the video you shot looks like, a computer monitor is the LAST place to look. You want to use an HDTV at least. I'd even say avoid computer displays with HDMI inputs...but even those are better than VGA. VGA is a very low quality connection. DVI, HDMI...those are better.
But if your intention is to view your video at full quality...an HDTV is your better option.

Streaming video with external monitor

I'm having an odd problem using an external monitor with my Macbook Air: I have the Air hooked up to my LCD TV, works like a charm. I like to watch streaming TV from various free online sites, and for some reason I can only get about 10 minutes' worth before my internet connection is lost. Literallly, my Air appears to be kicked off of my Airport network. If I unplug the external monitor, within a couple of seconds the video starts streaming normally again.
Anybody know what's going on?

Sounds like you could be having the core shutdown problems others have been reporting using an external monitor and video. If you search this forum you'll find several threads but I don't think there is a solution. Some have suggested the program coolbook.

Does the mini displayport able to transfer audio and video to an external monitor (example: a tv) using a 2011 13" MacBook Pro with an hdmi cable?

I was wondering this, because I want to hook up my 2011 MacBook Pro to a external monitor (TV) using an hdmi cable. This would be heplful before I buy a mini displayport to hdmi adapter, and then maybe find out that the mini displayport might not transfer audio, only video.

Yes, min Displayport supports audio and video for the 2011 MBP 13" via HDMI.

My macbook has problems streaming video when using an external monitor

I have a MacBook from 2007. I have a converter so that the MacBook can be connected to an external monitor, and have connected it to my TV. This works fine, but if I am streaming videos and trying to watch on the TV, the streaming becomes very choppy, almost like the wireless connection is too slow. If I unplug the computer from the TV, however, the streaming returns to normal. I previously connected to a TV with an S-video connection and the problem did not seem as prominent. Now I am connecting to a HD tv using an HDMI connection.
Any suggestions for how to alleviate this? I haven't updated or upgraded the memory or RAM, possibly that would help? Would the amount of files I am storing be causing the problem? I currently have 50 GB available.
Thanks for any help!

Make sure your Mac is set to a resolution and frequency that your monitor supports.
The other possibility is that your graphics card is fried, but that seems unlikely since your computer is new. Before too long, you should make sure your graphics card is OK using the Apple Hardware Test, but I'm not sure how reliable that is because it claims that my partially broken graphics card is OK.

New External Monitor for Logic on MacBook Pro - Suggestions

I'm in the painful process of updating my studio and now my large screen external monitor has started failing.
I know if this a pretty general question more suited to the MacBook Pro forum but I'd like some input from folks used to working with an application like Logic in a home studio environment.
I guess the issue for me is that I'm not getting any younger and my eyesight isn't what it used to be. One of the things specific to Logic and music software in general is that there are LOTS of very detailed dialog boxes with text that is not always height adjustable (yes I know about zooming and indeed I do lots of that but it gets quite distracting). The other factor is that I'm often recording and engineering myself which means I'll be sitting with a guitar in my lap or at a keyboard and can't always lean in too close to the monitor.
I solved this by buying a large 26" Acer which sits on my desk behind the Mackie MCU. To my left I've got the MacBook 15.4" Pro on a keyboard stand above my MIDI controller at a 45 degree angle to the desk.
It's worked quite well until the Acer seems to have become haunted. It will mysteriously reboot itself intermittently, going blank for a second, then showing the Acer logo and going back to picture. It will also turn itself on spontaneously when the computer is off (the status light is off and then turns itself on). It seems to detect when I'm in the middle of a really good session and starts resetting itself every 30 seconds or so. Then it will work fine sometimes for days or weeks at a time. I've checked it on 4 different computers, it malfunctions on all. I believe in may be a problem with one of the capacitors or the inverter, I'm not sure, but it's driving CRAZY at this point.
And of course now it's 3 months out of warranty and may be more expensive to fix than buying a new one.
So my issue is what monitor to replace it with. I've considered buying an Apple monitor, since the display is lovely to look at but there are a couple things that are deal breakers.
It's expensive. Very expensive.
Oddly you have to choose between a 24" and a 30", with nothing in between. Don't want to sound like Goldilocks here, but the 24 is tooooo small and the 30 is tooooo big.
Yeah I know bigger is usually better but since they bumped the native resolution of the 30" up to 2560x1600 it's really sharp but things like the menu text get really quite small. Yes you can reset to a lower non native resolution, but then you loose the sharpness. I tested Logic in the store on the 30" and it did look great but I found I actually had to move my whole body around to see things at the top and bottom of the screen.
Oh and did I mention that it's expensive? Jeez.
The 24" now seems to look a bit small to me after using the same resolution (1920x1200) on the Acer's 26" screen. (Ok, I think it's actually 25.5 but hey that half an inch can make a big difference and I will avoid making any bad jokes here).
And did I mention the Apple monitors are expensive? The 24" is almost 3 times as expensive as a cheaper alternative.
I also still have a PC here that I use (sorry) and the Apple monitors have very limited connectivity. So I think unfortunately the Apple monitors are out for me.
So I;m down to a couple other non Apple options. I will not buy an Acer again since I believe now that their quality control is not good and their support is absolutely atrocious. Shame I used to be a big fan of Acer PC's, but after owning a couple I'm steering clear.
My biggest issue right now is that most of the new budget monitors are geared toward 1080p HD uses so they are they are maxing out at 1920x1080 (16:9 aspect ratio instead of 1920x1200's 16:10). So the tradeoff here is that HD movies will look better in 16:9, but 16:10 gives you "squarer" pixels and more vertical resolution for screen hungry apps like Logic.
Any opinions on this? I'm a bit new to the Mac so I don't know if I'm really better off going with a 1920x1200 screen like the Apple monitors.
Also, I know this may just be a bug in the Acer's scaling, but if I switch to 1920x1080, I lose the menus off the top of the screen or if I adjust the vpos I lose the dock at the bottom. Downscaling to 1600x1050 or even 1024x768 works fine. If I get a 1080 screen and set the resolution appropriately will it work correctly and without too much distortion?
I'm also curious what is the best way to hook up the monitor? I'm currently using the DVI to VGA adapter that came with the MacBook. My Pro is the slighter older silver keyboard model so it has the standard DVI out. Will I see any real improvement by going over to using DVI directly?
Also I'm wondering how people feel about glossy vs matte for music. My current displays are the non-glossy and I do think I prefer them for detail work.
The candidates right now are
Hanns-G HH-281HPB 28" @300$. It's one of the only budget monitors that uses 1920x1200. All the right inputs (DVI, VGA). I'm just afraid this might be a bit too good to be true. It's really cheap and after having problems with a "cheap" Acer (although it wasn't so cheap 3 years ago!) I don't want similar problems. Stand has no swivel or tilt (a big problem for my use). Also that resolution on such a big screen might be good for me or it might look grainy I don't know I haven't seen it. Anybody have any experience with these?
Samsung P2770H 27" @339 Looks nice, good color. Sadly only 1080 native resolution. Stand doesn't swivel, but does tilt. No VGA input, so won't work with my old PC (although strangely it says it comes with a VGA cable). They get generally good reviews and I know Samsung makes very good flat panel TV's.
ViewSonic X Series VX2739WM 27" @350. Once again maxes out at 1080. It's fast (1ms), has VGA input. I've never been a big fan of ViewSonic but they do seem to have gotten better color-wise. Tilt no swivel and it's anti-glare (not sure this is a plus).
There are also similar options from HP, Asus, LG and Sceptre but they are all 1080. In fact outside of the Apples, the Hanns-G and a few expensive monitors from NEC they all seem to be 1080. So if I really want the 1200 the Hanns-G seems like the only way to go.
Any input here would be greatly appreciated.

No doubt, the Apple displays are gorgeous. The first time I saw the 30" display wow, I wanted one BAD and it's actually what prompted me to buy a "big" monitor. The colors are great with a rich wonderful saturation level and as usual for Apple the form factor design is stunning. You know for that picture quality I could even get over the sticker shock and save up for one.
Which is why I was so disappointed when I actually sat down in the store and started to use Logic on one. I imagine for doing video work, graphic design or darn near anything else, it would be great. But for Logic I just found myself bending and twisting trying to look at toolbar at the bottom and then up to look at the menus. And instrument or plugin displays that were hard coded to look OK at lower resolutions looked really, really tiny to me. For me and particularly using Logic having 2 slightly smaller displays at a 45 degree angle makes more sense.
And once again the 24 seems just a bit small. I don't understand why they have a 27" iMac but you can't buy a 27" display. So iMac 27" starting at 1699, subtract out the cost of the CPU and drive ie the Mini and I'd really buy one. Strangely you can buy a 21.5" or a 27" iMac. Or you can buy a 24" or 30" display. Hmmmm.
So don't get me wrong I'm not bashing Apple for being expensive. They put a lot of money into R&D and into really thinking about the form and the function of their products. As a recent convert from being a PC developer for 25+ years, hey I've more than sipped the Kool-Aid here, I've guzzled it. They make great products and yeah they're more expensive, because they ARE better! I've now got 2 MBP's, 2 iPods, I'm about to get an iPhone (silly "death grip" or not) and I really want an iPad. Heck I'd really love an 8 core MacPro if I could afford one (alas I can't).
I guess my only gripe here is that there always seems to be a little less choice in the Apple world. Yeah, I know they do a lot less volume than the PC clone world I just think that they always seem to have a big gap between the high end and low end with not enough in between. So you can choose between the lower end and one piece units with no expansion boards (the mini or the iMac) or go straight to monster tower MacPro (way over 3K with display). You can get a MacBook but then you have to put up with a small screen or go with MacBook Pro, which let's face it is a lot of computing power for someone who just wants to web surf and write some email without squinting.
So here I am stuck in the middle. I don't want to buy a HannspreeQG or another piece of junk that's going to last 3 years and 3 months because of a crappy $2 capacitor that no seems to able to fix or care about fixing. I'd like to buy a really nice Apple monitor, I just want a big monitor, not a huge one and not a "medium" one (I know I'm spoiled but 24" seems "medium" these days).
Sorry about the rant here but my monitor is shutting down every 30 seconds and I'm about to go completely insane and toss it out the window!!!
Really glad to hear about that 84' VGA cable. I never imagined such a thing existed or would work without some sort of signal boost on the way. Very cool for me. My electronic drum kit is in another room and I would love to have a small cheap monitor next to it for sequencing. I had my laptop on a stand next to it for a while but I began to get terrified that I'd let a drumstick slip and destroy my laptop screen. That would be a very bad thing. Thanks for the tip.

How to switch off internal macbook screen when using external monitor(s)

as far as i observed, adding external displays ( running different screens on them, not mirroring) to a macbook pro increases the gpu workload and with that comes temperature rise in the laptop and increase in ventilator noise - and probably increased hardware aging and risk of component faillure due to high temperature inside the laptop.
simply try connecting two external 27" screens and open some flash video on both of them. then run a temperature monitoring software and watch temps rise, compared to running same flash videos / demanding tasks only on one connected external screen or only on the laptop screen with no external monitor connected.
especially in mavericks, due to its increased background routines, such a set-up appears ever the more taxing, then again who does not love apple`s nice adds showing laptops with two 27” screens connected to it and the workspace vision they invoke....
i have seen temps around 100° to 102° celsius on a 13" macbook pro 2012 edition, which i would expect is territory where the cpu / gpu temp safety switches will trigger system shutdown any time soon ( hardware status before verified as fully in order by apple service and default osx installation)
imagine your anti-virus software starting some realtime content screening while runnign some demanding tasks already and the system shuts down easily (all such situation observed in reality)
(would be interesting to see how a retina display macbook fares with 2 external monitors running demanding tasks, considering the retina display already increased taxing for the gpu - any experience from users of such a setup would be very much appreciated as it will provide critical purchase decision intelligence for all of us envisioning a retina-book and two big screens adoring our desks...)
turning down the macbook`s built-in screen`s backlight may reduce power consumption but i have not seen any evidence that it switches off the gpu-to-screen feed and respective gpu load - it certainly did not prevent gpu, cpu, board, etc temps to rise to borderline levels.
so the key question here is, how to switch off the macbook pro`s built-in screen in order to avoid gpu cycles being wasted on that screen ( and the resulting heat developments) when working with big external screen(s) connected to the laptop ?

this thread talks about running several monitors as advertised by apple and running demanding task on them.
with the lid open, the keyboard offers a very efficiant heat escape vector, which is blocked when the lid is closed - this is a basic and commonsense insulation effect. this thread also mentions the use of temperature monitoring software and thus a repeatable test setup. the temps recorded were also mentioned. they rose when the lid was closed, the running task remaining unchanged. as far as i could track down the cpus in discussion will shut down around the 105 degree celsius range. i observed system shut downs when the system approached 103° celsius. not to mention that the fans will run loud well before that.
again this is on hardware checked and ok-ed by apple service.
the question still welcoming an expert answer: is there any way to switch off the built-in macbook monitor while the lid is open ?

2011 Macbook Pro External Monitor Problems

Hi all,
Looking through some of the threads, it appears that getting macbook pros to work with an external monitors is a big issue.
I've just bought a phillips 27" monitor and I'm having no luck whatsoever getting my MBP to see it. I've tried both HDMI and DVI using Apple's own mini adapters, but no matter I do, the monitor fails to detect any kind of signal and goes into sleep mode.
I occassionally get the blue screen flicker on my MBP as though it's trying to connect, but the monitor does nothing!!
I've tried most of the suggestions in other threads, which relate to earlier OSX versions, but nothing has helped.
I'm running 10.8.4 on a 2.2 GHz Intel Core i7.
If I fire up my Apple TV, I can use mirroring and the monitor displays my desktop no problem, but the picture quality is poor. So I guess the monitor works. I want to use a bigger screen as I use Logic Pro, so clarity is pretty essential when it comes to picture quality.
Any help would be most appreciated.
Best Regards
Phil

Hello Phil,
The following article provides a number of troubleshooting steps that I'd recommend looking into, especially testing with another display if possible, and resetting the MacBook Pro's parameter RAM and SMC.

HT3235 MacBook Air is connected to an external monitor via Apple Mini DisplayPort to VGA Adapter. At one time it worked just fine, now when I plug the monitor into the Mac, the mac screen goes blue and nothing appears on the monitor.

This monitor works, on a PC. Could the connector be bad or the port on the Mac Air? Any ideas?

You have the display set in Extended Desktop mode with the MacBook as the main screen. In System Preferences>Display on the MacBook screen there should be an Arrangement tab when you have the MacBook hooked up to the TV and both screens working. When you click the Arrangement tab do you see two monitors side by side? One of them will have a Menu Bar at the top. Just click on the Menu Bar and drag it to the second monitor. That will make the second monitor your main screen.
You can now use your MacBook in Clamshell Mode with a wired or Bluetooth keyboard and mouse. http://support.apple.com/kb/HT3131 When you disconnect from the TV your Menu Bar will automatically change back to the MacBook.
Or if you want to use the MacBook’s keyboard and trackpad to work on the MacBook screen while showing it on a TV you can check the Mirror Display box on the lower left hand side of the Arrangement tab under the two monitors box.
If you can’t see your MacBook screen because it’s broken or the backlight is off use the F7 key to switch between Extended Desktop and Mirror Display.
(From the MacBook User Guide: F7 (video mode toggle key) Switch between dual-display mode (extending the desktop across the built-in display and an external display) and video-mirroring mode (presenting the same information on both displays).

MacBook Pro 13 + LG W2240T - No external monitor display

Hi all. Have a brand new MacBook Pro 13 and LG W2240T connected with the MiniDisplay-->DVI-D adaptor. When I plug in the adaptor the screen on the Macbook flashes, the LG immediately says "DVI-D Power Save Mode" and then goes black. When I click "Detect Displays" it shows that no external monitor is attached. If I unplug the connector the MacBook display flashes. I think the Macbook is seeing something but it isnt sending a signal to the display. If I unplug the cable from the monitor I get a general "check signal" message floating around the screen. Dont think it is a problem with the screen. I dont want to have to shell out another $30 for a MiniDisplay -->VGA adaptor and use an analogue signal with the beautiful new digital display.
Any hints or suggestions appreciated.

I'm having the same trouble. Actually, my Macbook detects the monitor but no signal is reaching it. I am using a DVI-A cable from what I can tell. There appears to be a DVI-D or DVI-2 type cable available as well.
The connection is as follows:
Macbook Mini Display Video output to (Mini Display/DVI adaptor) then the DVI-A cable to a DVI/VGA adapptor (sub-D monitor connector) to the external video monitor input. I can see a "No Signal" message when I use a "picture in picture" function on the external monitor screen but get just a black screen with the monitor set to full screen VGA input.
So do we think the trouble is the type of DVI cable or is there some further Mac secret handshake that I need to prompt the output from the Macbook. The odd thing (to me anyway) is that the Macbook recognizes the monitor by its brand and model number after doing a "Discover Monitors" search. But the signal does not reach the monitor and I don't know if there is anything else I need to do or if it just doesn't work.
Further info is that I just tried disconnecting the DVI input, which I use as the main video connection to my monitor and I get the stock "arora" screen image from the Macbook but that's not what is currently being viewed on the Macbook screen. So perhaps I can just set the Macbook to "Mirror" the displays and use the DVI connector. The trouble with that is that the DVI connector is occupied on both of my external monitors. I haven't even tried the other monitor yet as it's a plasma TV in another location.
What do you guys and gals think is the best and most cost effective fix here? I just want to be able to output signal from my Macbook onto the larger displays so that I can work more comfortably.

Problems connecting my MacBook Pro to an external monitor

For the past 2 years, I have regularly connected my MacBook Pro to an external monitor (Dell SR2320L) using a VGA cable. When I do so, the picture automatically comes up in the maximum resolution of the external monitor (1920 x 1080). However, just in the past few weeks, the picture on my external monitor automatically comes up in 1600 x 1200 instead. When I click on the display menu in the upper right corner of my screen, there isn't even an option for 1920 x 1080 anymore. I've tried restarting my computer and even unplugging and replugging in the cable, but nothing seems to fix the problem. However, on at least some occasions, the problem seems to fix itself after about a day or so of use, and the picture reverts back to 1920 x 1080. I should note a couple of things: when I connect another MacBook to my monitor, the display automatically comes up in 1920 x 1080. And when I connect my Macbook to a different display, I have the same problem as I have with my display. So I think the issue is definitely with my computer, not my monitor. Does anyone have a suggestion about how to solve this problem? Or, when the problem arises, is there anything I can do to reset the display to 1920 x 1080 other than waiting for the problem to fix itself? Any suggestions woudl be greatly appreciated!

Can i use my 21.5" imac as an external monitor for my macbook pro?

I have a 21.5" iMac (with Intel processor) that I'm trying to use an external monitor for a new Macbook Pro. Both machines have a thunderbolt input. I bought a Belkin mini displayport to mini displayport connector, but my macbook is not displaying on the iMac. I saw videos online showing this done with the 27" iMac, saying you just needed to press Command+F2, but that is not working for me. I can't seem to find any posts confiming if I can use my 21.5" iMac this way though.

Can I use my iMac 2009 as an external monitor for a MacBook Pro

I will soon be getting a new MacBook Pro with Retina display. It has an HDMI port.
My current iMac 21.5" late 2009 model seems to have a port with what looks like a little monitor symbol, next to the firewire port. And the specs say:
Graphics and video support
NVIDIA GeForce 9400M graphics processor with 256MB of DDR3 SDRAM shared with main memory3
ATI Radeon HD 4670 graphics processor with 256MB of GDDR3 memory
Built-in iSight camera
Mini DisplayPort output port with support for DVI, VGA, and dual-link DVI (adapters sold separately).
Support for extended desktop and video mirroring modes
Simultaneously supports full native resolution on the built-in display and up to a 30-inch display (2560 by 1600 pixels) on an external display
Does this mean that port is just for video output to an external monitor? Or is is possible to also do video in?
On the one hand it feels like a waste to use a perfectly good iMac as a monitor. But the MacBook Pro actually has better specs, and so I was wondering if it is possible anyway.
Thanks,
doug

Thanks for your reply. After reading the article though, I'm still not really sure what the answer is. For example, you mention something that can be done, with some hurdles to go through, for 27" iMacs. Mine is a 21.5" iMac, but seems to have the same port you mentioned in the article. Or maybe it isn't. Anyway, I'm still not sure if it is possible after reading that. Interesting information though.

Macbook Pro detects external monitor as TV

Hi,
I recently purchased a new MacBook Pro with Retina display. I plugged in an external monitor for the first time today and noticed that the screen looked blurry. I have seen on other forums that its a font smoothing issue but I ran that command in the terminal with no sucess. In my case its just not the font that is blurry, everything is blurry. I believe the problem is stemming from OS X detecting my external monitor as a television. Is there anything I can do to fix the issue or am I stuck waiting for Apple to update their video drivers. As a developer I like having as much screen space as possible but reading text on the secondary monitor is giving me a headache its so blurry.
My external monitor is a 24 inch Samsung with a max resolution of 1920x1080. I am connecting it via the Apple mini display port to DVI adapter.

It was set to 1080p, 1920x1080 did not show up as an option (even when holding the option key). 1080p should be equivlant. As as experiment I grabbed another monitor that was not being used. It is a 22 inch LG with a maximum display of 1920x1080, and its currently set to 1920x1080. The issue is a little different, was not detected as a TV this time, but the screen still looks blurry. There may be some improvement but not much.
