Connecting Mid 2012 MBPro to External Monitor

I've recently purchased a Mini Display Port to Display Port cable to connect my Mid 2012 MacBook Pro (Non Retina) to a 23" Asus PA238Q IPS Monitor, when I connect it It displays an image ok, it sometimes flickers but the main problem is it won't display an image in any other resolution other than the MacBook Pros native resolution.
The main reason I wanted to use an external monitor from time to time is for photography related work and using an IPS Monitor with a resolution of 1920x1080 would be hugely beneficial, not to mention the fact it's 23" not 15"
Is there a way I can get my MBPro to display the image properly at 1920x1080?
Huge thanks in advance for any help!

Can you post a screen shot of your Displays preference pane -> http://support.apple.com/kb/PH4391?
Should look something like this:

Connecting the T410s to an external monitor

1) Excuse the ignorant question but how would you connect the T410s to an external monitor? The T410s has a DisplayPort port, but what if the monitor does not have a DisplayPort port but an HDMI port?
2) Which leads into my second question. How would I connect the T410s to two external monitors? I guess whatever the answer is to the above question, but connect some kind of a splitter coming out of the T410s DisplayPort port?
3) And lastly, take a look at this link...
http://shop.lenovo.com/SEUILibrary/controller/e/web/LenovoPortal/en_US/catalog.workflow:category.details?current-catalog-id=12F0696583E04D86B9B79B0FEC01C087&current-category-id=19C791A03AF24034A0011B825513BCED&tabname=Gallery
Once you get there, click on T400s below the thumbnails. If that long link I pasted does not work right, it is the T-series gallery on Lenovo's site. In one of the pictures, it shows the T400s connected to two external monitors, but does not say how. They brag at how you can export 2560x1600 to two monitors without the use of a dock. Is this possible even though the T410s video card tops out at 1440x900?
Thank you.

Solved!
Go to Solution.

Thank you, lead_org. You've been very helpful. Last 2 questions hopefully.
1) Regarding the use of DisplayPort on the Mini Dock Plus, since DisplayPort transmits audio as well as video (unlike the old style VGA which only sent video), if I connected the Mini Dock Plus to the HDMI port of my monitor (using a DP-to-HDMI adapter of course) would I lose audio out coming out of the green miniplug port on the mini dock, since the system might assume I want all audio to go through the DisplayPort cable? I have seperate external speakers I want to use and not the ones on the monitor.
2) Do you lose any quality when you connect to an external monitor using a Mini Dock, as opposed to connecting directly from the T410s itself? The reason I'm asking is that some people claimed that using the green miniplug audio port on the dock generates a much lower volume than if they were to plug the speakers directly into the laptop instead.

Macbook Pro(Mid-2014) Not Detecting External Monitor

Hi everyone, I'm trying to connect my MBP to an external monitor via HDMI. Since my MBP has an HDMI port built in, I'm not using any adapters between it and the monitor. But nothing is happening when I connect the HDMI cable, my MBP does not seem to detect it. I have tested my monitor with that HDMI cable on a desktop PC, and it all works without any issues there, so I reckon it must be something on the MBP end of the connection. But what could it possibly be? I have looked through forums and read countless threads about external display problems, but have not found any info that could identify the problem. I have tried booting my MBP and/or turning on my monitor before and after connecting the HDMI cable, and there was never even a hint of detection.
I'm running OS X Yosemite 10.10.1, and the external monitor in question is an HP Pavilion 27Xi in 1080p.

I have a problem connecting external display (Dell U2311H) to my 13" MacBook Pro (Early 2011).
I use Tecklink Mini DasplayPort to HDMI adapter (http://www.techlink.uk.com/products/wires_cables/wiresmedia/wiresmedia_media/wir esmedia_mini_displayport_plug_to_hdmi_plug), but since U2311H doesn't have HDMI input, I also use Manhattan DisplayPort to HDMI Adapter (http://www.manhattan-products.com/en-US/products/8101-displayport-adapter).
And nothing.
The display is not detected, no picture or even external monitor presence at all.
I even reset PRAM, and installed 10.8.2 Supplementary update.
I also plugged and unplugged all I could, with no luck.
As I can see on Apple discussion, it is a common problem with 2011 MacBook Pro's.
It seems like the problem is in Thundebolt port, it somehow does not work properly.

HT3924 Using a 27-inch iMac (Mid 2012) as an external display?

As I have been using MacBook Pro (Mid 2010) and Mac Air (Mid 2011) for business purpose, I wanna use them working at home.
I really expected that there was new cinema display with Retina display, but there wasn't. However, New iMac looks really nice & I would love to buy it.
But Using a 27-inch iMac(Mid 2012) as an external display is one of my important required function to buy it.
What do you think? is a 27-inch iMac (Mid 2012) able to use target display mode?

there's a lot of misinformation so far here. Yes you can use all the 27-inch iMacs as external displays.
However there a few problems.
2009-2010 27-inch iMacs can only work with Apple computers that have the Mini-DisplayPort.
2011-2012 21-inch and 27-inch iMacs can only work as a display with Macs that have thunderbolt ports.
so as long as your 2011 MBA has thunderbolt, the new one will do fine. your 2010 MBP will not be able to use the iMac as a display.

"How do I find that IP address because I put in the 192.168.1.8.."
That's not the router's IP address. Most likely it will be 192.168.1.1
System Preferences>Network>Advanced>TCP/IP should show it.

Can I use my macbook pro mid 2012 as an external display using thunderbolt port

Hi,
I want to use my macbook pro (mid 2012) screen as an external display for a raspberry pi using a HDMI to Thunderbolt cable, via the thunderbolt port on the macbook pro. Would this be possible? Can the macbook pro's thunder bolt port act as an input and is any additional software required?
I look forward to hearing from you.
Thanks in advance!

Welcome to Apple Support Communities
You are referring to Target Display mode. Target Display mode can only be used in 27-inch iMacs and iMacs with Thunderbolt, not MacBooks Pro > http://support.apple.com/kb/PH11302
Unfortunately, you can't use the MacBook Pro as a display. It doesn't support the monitor mode

HOT HOT HOT HOT!!! Mac Book Pro Retina, Mid 2012 with 2 external Displays HOT HOT HOT HOT!!!

Hi,
i think i have a serious heat problem and i am a bit afraid of melting the mac book (It happend before with an older mac book pro, graphic card melted...yes, it did...)
i own a Retina, Mid 2012
Processor 2.6 GHz Intel Core i7
Memory 16 GB 1600 MHz DDR3
Graphics NVIDIA GeForce GT 650M 1024 MB
Software OS X 10.8.4 (12E55)
in use with 2 external Monitors, one TB Display and one Eizo (27" same resolution as TB) via display port and doing lots of stats with Stata and R on it and it get hot like **** (temperature monitor says around 95-100° degrees on graphic processor diod and around 80° on the chip.
furthermore, it creates kind of random kernel tasks with % CPU usage up to 500% (i read somewhere it does it to keeps internal cooling up...(??) ) and it is getting really slow... almost unusable.
Is this still healthy and the way it should be when i use it with 2 monitors?
Will i ruin it by using it like this all day long?
Apple says it could handle two displays. I think it can`t without killing itself on the long run (if you still USE it)
any ideas what to do? i allready use a cooling pad for it (cheap revoltec) but it does not really help, the macs and the pads fans run like crazy, its pretty noisy and gets really hot anyway
Any experiences with 2 displays?
is there anything i can do about it?
Better cooling pad solutions???
Any other solutions??
Any ideas welcome
Thanks & Best
Franz

Hm, i cannot reproduce the kernel_task thing right now, but this is my temp after working with 2 screens for 10 minutes. is this normal?
100° cpu, 96° on the diode, and 78 on GPU chip? it even was 82 once.
when do i reach critical limits?
apple?

2012 iMac as external monitor

Hi, got 2012 imac that I want to use as a external monitor from my PC with has displayport out.
From research I see that to use it via HDMI or DVI you have to make sure you get an expensive bi-directional cable, but all the cables I can see are just called mini-displayport to displayport, where as I want to go from displayport to mini-displayport.
Do I need to a different cable or are mini-displayport to displayport cables bi-directional?
Cheers

Hi, I don't think you can do it...
Mid 2011s & up need Thunderbolt cable...

Connecting MBA 2012 to three External Displays

I am looking to purchase a 2012 MBA, contingent upon connecting to three external displays. As the MBA 2012 has a USB3.0 and a Thunderbolt port, I plan to use -
- A Plugable UGA-2K-A USB 2.0 adapter to convert the USB3.0 to a HDMI/DVI input on a 21 monitor (For text only)
- Use a DualHead2Go Digital SE to connect it from the Thunderbolt port to the HDMI/DVI inputs of the two external monitors (run two different applications and not a stretched image)
I am wondering if this would work (albeit with minimal lag) or if are there any other alternatives to hooking it up to three external monitors. Thanks

Did you ever get this figured out?

How to connect mid 2012 MacBook Pro to home theater system

Okay so I'm looking at purchasing a home theater system and was wanting to know the best way to connect my mid 2012 MacBook Pro to the home theater system and TV. I am wanting to play both movies (Netflix etc) and music. Will my MacBook play 5.1 surround sound to the home theater system? Whats the best way to connect this all up? MacBook audio to the home theater system via Digital Optical from the headphone port with a 3.5mm to toslink adapter and then video to the TV via HDMI cable from the thunderbolt port with thunderbolt to HDMI adapter? My thinking was to separate the video and audio to get the best picture and sound. Any help/advice on this would be greatly appreciated.

Will my MacBook play 5.1 surround sound to the home theater system?
Yes.
Whats the best way to connect this all up?
An AppleTV or any AirPlay-enabled AVR. AirPlay is wireless, though you could use wired Ethernet if you want to avoid all the potential problems associated with wireless. Make sure it specifically says AirPlay which is Apple's proprietary technology. There are quite a few of them to choose from today. Denon is one, I believe Pioneer, there may be others. Shop around. The AppleTV's price was recently reduced to $69 US and may actually be the most cost-effective solution, allowing you to research the best AVR for your needs. The AppleTV has both HDMI (audio and video) and optical audio outputs.
MacBook audio to the home theater system via Digital Optical from the headphone port with a 3.5mm to toslink adapter and then video to the TV via HDMI cable from the thunderbolt port with thunderbolt to HDMI adapter?
Way too complicated But if you really don't want to use AirPlay, you can purchase an inexpensive (< $10) Thunderbolt to HDMI adapter and an equally inexpensive (<$3) HDMI cable to any HDMI input on your AVR.
My thinking was to separate the video and audio to get the best picture and sound.
It makes absolutely no difference. HDMI and optical audio use completely identical digital audio signals.

Cant connect MacBook Pro to LG external monitor.

I used a mini display port to hdmi cable that is connected to the monitor however, no signal is detected. I went to the display tab and it is says the 'arrangement' tab is hidden as it is only available when another device is connected. This makes me think neither device is aware of the connection. Can anyone please help?

Greetings rtmoms,
Welcome to the Apple Support Communities!
I understand that you are having an issue where your external monitor, when connected to your MacBook Pro, shows no video or signal. In this situation, I would recommend reading over and working through the steps in the attached article.

Connect firewire audio interface and external monitor

I have just bought my MacBook Pro 13 and I will mainly use it for audio recording . I have connect my audio interface through the firewire port. I need to connect an external monitor . The only available ports are thunderbolt and USB . Can I connect a monitor with these available ports ?

Hi charisio,
Thanks for visiting Apple Support Communities.
If you would like to connect an external display to your MacBook Pro, you can use the Thunderbolt port. See these articles for some good information about Thunderbolt:

Connecting Dynadock to a second external monitor with a splitter

Hey guys -
I have a Samsung Series 9 which I have connected to the Dynadock3.0. I have two additional external monitors which I wanted to connect via the dynadock. I used a vga splitter to connect to the two monitors (dell u2312hm) via vga cables and then used the vga-to-dvi converter to connect to the Dynadock. Unfortunately the computer only recognizes both the external monitors as one screen and while I am able to extend between my laptop screen and the external monitors, both the external monitors duplicate the same screen.
Help!

Any help here would be greatly appreciated

Mid 2013 Macbook Air External Monitor Issues

I am running on 10.8.4 and am using a fully upgraded 2013 macbook air. i7, 8gb of ram, 512 ssd. Recently, I have been having issues connecting my computer to external displays. I have reset the PRAM, and the SMC multiple time with no luck. I have also deleted the windowserver plist files and that did not seem to do anything as well. The issue is as follows: when I plug in my laptop through the thunderbold port to the hdmi on my tv, the screen on my laptop goes blue, as normal, but then nothing shows up on my tv. I have used the same cable with my roomates macbook and it works just fine, on multiple tv's. Mine is not able to connect to any of those tv's. When looking at the display settings in system preferences, I do not see that it ahs detected any external displays. I am not sure what to do at this point.

I think I have fixed it somehow. I reset the PRAM while the tv was plugged in and it worked, but it seems that something may be wrong with my video card, because there was a bunch of fuzziness and weird colors on my computer's monitor for a few seconds before everything went to normal
