Put the brightness of your computer as low as possible (mine would completely dim so i can't see it) most likely using less battery power or even less than it would while the display is fully brightened. Make sure your settings are set to mirror on the display only.

Max supposed supported resolution on that card for an external monitor is 2560x1600, I'm afraid. The 2013 can do 4k, but not the 2012.

Only 2013 Macs (and upwards) are compatible with 4K. Current retina MacBook Pro (13" and 15") are compatible with 4K but only at 24Hz

See my answer to Mousing over to external display Works just as well for vertical as horizontal.

The USB-Hub is not the Problem. If you only use one Displaylink Adapter, it works fine. I have the same on MachBook Pro Late 2008 and 2 Adapters.

Right-click on the drives on the main display create an alias move alias icon to second screen As I've only one screen, I can't verify whether this works in all situations.

The external display is not set as a mirror of the main display but rather as an extension of it. So you can drag the external drive icon (or any file/folder/window) from one display onto the other. However, this will not 'stick' as when you disconnect the drive and reconnect it, the system will mount the drive icon back onto the primary display (the one ...

DisplayPad It works well for my iPad mini with Retina display. I've tried to use iDisplay, but soon after purchasing it I suddenly discovered it doesn't support retina displays.

I do not know what is it that you trying to do. The HDMI cabled external monitor has nothing to do with the Network (Internet). Also the "My Trace route" applications is bit out of date. I would suggest to use the build in app called Network Utility to check the internet connection parameters including the trace route. The Network Utility app is located ...

I was able to use the previously suggested ControlPlane app along with some simple shell scripts to get this working. First, I created a context for having my Thunderbolt Display plugged in ("Desk"), and one that negated that choice ("Lap"). Next, I made two simple shell scripts to toggle the autohide setting and restart the Dock. I put them in a ...

This FAQ from Apple: http://support.apple.com/kb/HT3382#5 Key part: 6 Can other video adapters be connected or "daisy-chained" to Apple Mini DisplayPort adapters? No, you should not connect Apple Mini DisplayPort adapters to any other video adapters. Connect your computer directly to an external display via one Mini DisplayPort adapter. So, ...

Open System Information, then under Hardware select Mini DisplayPort. This will tell you about the firmware of the port controller and more.

I have the same problem on my Dell U2713HM monitor with a new Macbook Pro w/Retina. To illustrate, here's a screenshot of a document shown at 100% in Preview (left) and Adobe Reader (right): On my Retina screen, the document on the left looks great. So I guess this is a clear-cut Retina issue. Don't bother running the Ruby script cited elsewhere (the one ...

The 2011 MBP (MacBookPro8,1) has thunderbolt, so either your machine is not a 2011, or it has thunderbolt. the 2010 MacBook Pros have MDP that supports audio as well as video (I have a 2009 which only does video). Keep in mind that MDP and Thunderbolt look identical.

It turns out the cause is Spotify. It seems to be a bug with the Spotify app. Yet no bug fix has been released. If you have spotify running, kill it and see if you get this issue still.

I'd start by suspecting the thunderbolt->DVI adapter you're using (you are using DVI, right?). Do the dots go away if you just unplug and replug the adapter, or do you actually have to power cycle the unit?

You ABSOLUTELY can do this. The statement on the box is wrong. You can use either two mini-display port to displayport cables, or two Thunderbolt cables. My statement was based on the fact that you can (according to Apple's documentation) run two Thunderbolt monitors on that laptop, and the available resolution on the Thunderbolt cable is clearly capable ...

Replacing your optical drive would seem a logic choice to me. No wires, fast transfer speeds and you have your disk always with you. If storage is your main concert, just go for an HD (And replace your SSD with a bigger one while you are at it...) It is not expensive at all. You need a philips screwdriver, a hard drive enclosure kit specially made to fit ...

I came up with a workaround when I was finalizing the question: mirror only the phantom displays. To do this, go to System Preferences-> Displays and click Arrange (click gather windows if you don't see an option to mirror displays). While holding the Option key, drag the windows that you wish to mirror on top of one another. (In my case, I mirrored all ...

Best workaround I have found so far: When the spaces are arranged vertically, you can move the dock by switching which display is the primary display. In Settings > Displays > Arrangement, drag the thin grey bar (representing the menu bar) from the box representing the current display with the dock to the box to the other display's box. Bar in bottom ...

I just had this same problem in Mavericks, I managed to solve the problem by following these steps: Take the pointer to an edge of the window that moved off screen, for example to the edge on the right. When you see the resize icon (in my case the horizontal resize icon) click and hold. While "holding down the click" drag the window. Voila!

Can I change the brightness on a secondary display? This thread (although the question is slightly different) offers answers to your question.

You can connect the Thunderbolt port to a VGA adapter for your VGA monitor. I'm pretty sure it does not matter. I'm not sure if a simple HDMI-to-VGA adapter even exists. The Macbook Retina that I have has 2 thunderbolt ports and one normal-size HDMI port. This MacRumors topic contains some useful info as well: ...

You can drag the screens into the arrangement you wish in the Displays Control Panel, just click, hold, drag. The screen you are moving will show a red surround on both the panel & the display itself, so you know which is which.

I have found that you can move the app window if you position the mouse over the edge to get the horizontal or vertical resize arrows. The trick is to move the mouse horizontally if you have the vertical resize arrows or vertically if you have the horizontal resize arrows. It is a bit tricky, but it works on Mavericks 10.9.x This trick does not work with ...

This problem could also be caused by a missing or improper HDCP signal coming from the MiniDisplayport-to-HDMI adapter. I experienced the same issue with my MacbookPro (late 2008) and a Bravia TV. I tried one cable with a MiniDisplayport connector on one end and HDMI plug at the other. This worked fine between my MBP and a computer monitor or a beamer, but ...

Seems to be a misbehaving Mini DisplayPort-VGA adapter. The monitor works on an old PC with VGA out.


0

You have a solid troubleshooting technique, so I'd agree the adapter, or the VGA cable are likely culprits. Sometimes it's as easy as the cable not sitting well in the connector, and that could mean it connects the necessary pins for detection/sync but not for actual display. One other thing I could think of is if the monitor has a source selector, i e if ...

It was completely the cable. I used a Mini DisplayPort to DisplayPort cable and it works perfectly.
