LG IPS display with HDMI plugged to Macbook Pro worked only once

Hi!
I bought this display (http://www.lg.com/us/monitors/lg-IPS237L-BN-led-monitor).
I plugged it to my Macbook Pro 13 with Mac OS X Mountain Lion updated to the latest version using a HDMI cable and a HDMI to Mini Displayport conversor. It didn't work the first time, but after searching in the forums i tried deleting the file /Library/Preferences/com.apple.windowserver.plist and it worked! Later on my Mac ran out of baterry and shutdown. I turned it on again but since then, i haven't been able to get the display working. It just says "no signal", and i can see it gets recognized in someway by Mac OS because when i plug it or turn it on the laptop screen goes blue, but then nothing happens and i can't find the display under System Preferences > Displays.
I have tried the following:
- Deleting all the files related to com.apple.windowserver.plist (including those under ~/Library/Preferences/ByHost)
- Delete also those files in single user mode and also in verbose mode.
- Deleted Overrides files for displays (/System/Library/Displays/Overrides)
- Restarted in Safe mode.
- Deleted .GlobalPreferences files
- Reset NVRAM and SMC
- As a last resort i tried reinstalling Mac OS. That didn't work either.
I have tried those and a couple of things more that i can't rememeber, but at this point i'm clueless. I guess my Mac is caching something related to the display and that's why it doesn't work. It's not certainly a cable or device problem since i already could make it work once.
Any ideas what could i be missing? I'm pretty sad i can't use my new display! Any help appreciated!

It was the **** cable. As it worked once, i never cared to test with another one. As soon as i did, it worked. So many wasted hours but pretty happy now.

How to Force mac Thunderbolt External Display with Integrated GPU for Macbook Pro 2012?

I have been getting GPU Panic whenever I use external Thunderbolt Display.
Not sure whether this is software after(Mavericks) or hardware, if anybody could shed some light I would appreciate it.
The Current Discrete GPU will only work for few seconds 10 sec max before it became blank and require you to force shutdown. This also happened even without external display Blank and GPU Panic upon restart. So I suspected either the discrete GPU failure or software in Mavericks.
But at the moment I'm looking for workaround so I can use the intel intergrated GPU to use my Mac Thunderbolt External Display.
Thank you in advance for any input.

I have the same problem with an early 2013 macbook pro. gfxCardStatus ( http://gfx.io/ ) will allow you to force integrated and not do dynamic switching, however the external display still doesn't work.

Why can't we have superdrive and retina display and HDMI in one macbook pro?

Its good to have a lighter macbook pro for those who don't need the superdrive....BUT, What about those (like myself) who desperately want a superdrive in their macbook pro and also the retina display!! And, Why can't we have a regular HDMI in macbook pro with a superdrive....this is so frustrating! Whats wrong with apple!

I might actually buy a windows laptop. So sad.
No need, as long as Apple continues to offer a notebook line-up that includes built-in optical drives, to buy a Windows machine... yet.
As I said, the only thing that I use my SuperDrive for now is backups of all those digital software deliveries, documents, etc. If I finally break down and buy an external Blu-ray drive, I won't use the SuperDrive at all. But right now I have almost 12 years of back-ups on DVD, both single and dual layer - so, for now, I need my optical drive.
I'm hoping that - one day - Apple will sell MacBook Pros with Blu-ray drives. Hey, I can wish, right?

Pink and black blocky display with horizontal lines on MacBook Pro

Hello all.
I have an early 2006 MPB and recently (December '11), the display suddenly turned to a pink and black blocky pattern. Everytthing froze and a series of horizontal lines appeared next to the cursor. After resetting the PRAM to no avail, I did a clean install of snow leopard. Everything was then fine until now, a week later, it's happened again. Any ideas? I have photos of what it looks like but can't see anywhere I can post

Here's what it's looking like

Yes, I'm suspecting it might be something like that.

You can't. Theoretically, Thunderbolt devices that only transfer video and audio should work with Mini DisplayPort MacBooks like yours, but it's not the case of the Thunderbolt Display. Its firmware doesn't allow it to be used with non-Thunderbolt Macs, so you can't use the Thunderbolt Display with the Mid 2010 MacBook Pro.
Instead, you have to look for another screen, or you can get an adapter and connect the MacBook Pro to a TV

Will 2008 macbook pro work with 27" cinema display?

November macbook pro 13"
will this work seamlessly with new cinema diaplay?
also - how come it's not HD but 30" is? thanks.

I am using and enjoying my 27" Cinema Display with my October 2008 MacBook Pro 5,1. The display is breathtaking and its operation with my computer is flawless. I strongly recommend that you consider getting an Apple external keyboard and Magic Trackpad to use with your MBP and Cinema Display.
If you have a MBP 5,1 as your post indicates, it has both a 9400M and a 9600M GT GPU, not a 9200M.

How to connect my old 20in Cinema Display to my thunderbolt new MacBook Pro?

Hi everyone, I just brought a new MacBook Pro to replace a older model(brought earlier 2010), and a new thunderbolt Cinema Display. I have a old 20 inch LCD Cinema Display all the way from 2005 and brought a mini display port for my old MacBook Pro, worked just fine. However with the new Thunderbolt Display, I noticed there's another thunderbolt port behind and was thinking to connect my old Cinema Display as a secondary monitor. I've brought a thunderbolt port from amazon (http://www.amazon.com/dp/B007KB0EGC/ref=pe_175190_21431760_M3T1_ST1_dp_1 ), but my old monitor still shows black. What did I do wrong here? Thanks!

So currently there are two displays and you expect there to be three?
Can you swap the displays just to make sure there is nothing else wrong?
That is confirm:
1) MBP -> Display A works
2) MBP -> Display B works
Then try:
MBP +-> Display A
|
+-> Display B

HDMI failure on MacBook Pro Retina Display

When I connect my MacBook Pro Retina Display (late Aug 2012) with HDMI cable to my HD TV their both screens turn blue and the Mac needs reboot. I used that same TV with my 3 yo MacBook Pro to watch over the HDMI (with some extra cabling) and it was fine. Why is it happening this now with the New Retina dispaly?

Hey, I have the same problem too. It is making me angry. Both my thunderbolt outputs work, but the hdmi freezes both screens. I then have to shut the computer off by holding the power button and re-boot. Have you found a solution? I NEED my hdmi port. Please get back to me. Thanks!

Any help?

First than all, check your video input (TV Video), check in all possible channels, and make sure the HDMI is plugged in correctly. If you did plug it in correctly, and checked all possible channels of Video Input, and it doesn't appear, you should try rebooting your MacBook Pro (with the HDMI disconnected), after it's back on, try plugging it in back again. If the problem persists, I recommend you to go to a Certified Apple Store, and have them check it.
Hope this helps!
Later.

Having trouble with image size on new HP2311x display with 4 year old MacBook. Image too small. Do I have to stay in mirror mode? I have messed with OSD and Image Control menus on display and have gotten nowhere. Help?

Have just installed new HP 2311x display withe 4 year old MacBook. VGA cable. In mirror mode, at high resolution of 1920x1080, image size on HP display is too small. How can I get it to fill screen? If not in mirror mode, the display looks good, only I can't get the top menu bar (tried to drag it) nor the rest of the desktop. Help?

NO power on my MacbookPro: it all started with Battery of my MacBook Pro saying it was not charging (even if the pro was plugged) and it then switched off and now wont turn back on. There is no light on the magsafe and no startup noises at all.

If you have Apple Care or your computer is still under warranty, give them a call and get a case number. Otherwise, take the computer to an Apple store or an AASP. Whichever is more convenient for you.

Why is it that when I plug my Macbook Pro to an external monitor, the external monitor turns black and shows the mouse only

Why is it that when I plug my Macbook Pro to an external monitor, the external monitor turns black and shows the mouse only

Hi, yes preferences sees there is a second display it recognises what make of monitor it is etc but I just get a blank blue screen on the monitor when I change it to the hdmi setting! I have tried with mirroring on and off, rearranging the displays in the preference window and lots of different resolution settings but with no difference.
An old MacBook connects fine so the monitor and hdmi port must be okay. I'm sure we have used the cable before but it could have been with the previous MacBook Air. The current one I'm using is a mid 2011 version running lion and is (according to software update) all up to date.
Any thoughts or help would be appreciated!

How to properly disconnect a Mini Display Port (MDP) from a Macbook Pro 2012, 1,9?

Hello:
I was wondering if any Macxperts out there had any idea on how to properly disconnect a MDP Thunderbolt Cable from a 2012 1,9 Gen. Macbook Pro. From my experience with older Macbooks the command was "Command + F7" or something of the sort.
On my Macbook Pro 2012, there is no such button or commend to properly disconnect the plug; as if one were to disconnect or "eject" an external HD. I have read some articles on Google that some people just disconnect the plug and that action is sufice to disconnect an external video projection (Ex: Flat Screen Samsung).
Can a Macxpert or Genius comment on this piece of information? I would really apprecite some light shed on this situation. I just don't see unpluggin a cable connected to a video source enough to properly shut off a connection with out damaging the Macbook Pro's video card.
Thanks
A

Hello, Niel:
I just answer my own question. Forgive me but I am not up-to-date on the techlingo (Hot Swappable) but I just googled the term and found my answer.
Thanks again.
