I know this problem has been answered before, but I could not make any of the presented solutions work for me. I just bought a Phillips 245B monitor with QHD (2560x1440) so I could run it in native resolution with my MacBook Pro (15-inch, Mid 2010) and its NVIDIA GeForce GT 330M GPU. Unfortunately the maximum resolution that IOS lets me choose is 1080p. I tried already:  Preferences -&gt; Displays -&gt; option-click on Scaled Resetting the PRAM A different Mini Display Port to HDMI adapter (from Gravis) and a Mini Display Port to display port adapter, which resulted in a &quot;no video output&quot; on the monitor. Creating a new EDID file like , which resulted in the monitor staying black.  I hope one of you guys can help me :-) Cheers
MacBook Pro (15-inch, 2016) with 2 USB-C to HDMI adapters. The setup works great if I start up in that configuration.   If I connect the adapters while the machine is running or simply sleeping, one of the monitors will never get a signal and stay in low power mode. The OS sees the monitor, it shows in the display arrangement settings and I can move the mouse into it, but until I restart, I can't see anything on it.  Once I have restarted I can let the machine sleep or whatever, and the display still works unless I disconnect the adapter. As soon as I do that a restart is required to use it again.

So I thought about extending the problem a bit to understand more about it. In this modification of the Monty Hall Problem, instead of three doors, we have four (or maybe $n$) doors, one with a car and the other three (or $n-1$) with a goat each (I want the car).  We need to choose any one of the doors. After we have chosen the door, Monty deliberately reveals one of the doors that has a goat and asks us if we wish to change our choice.  So should we switch the door we have chosen, or does it not matter if we switch or stay with our choice?  It would be even better if we knew the probability of winning upon switching given that Monty opens $k$ doors. Is there any API function for shutting down Windows while installing any pending updates? How do I avoid checking for updates for a specific module? In a current project I have had to patch the life out of a few modules (node hierarchy, workbench access and a few more). These modules are now absolutely perfect for the project's needs and are very unlikely to break with future updates to core.  That being said, when the app is handed over the clients will have full (user 1) access to the system and will therefore be warned when these modules have available updates. And they will update them, no matter how many times I beg them not to (oh how easy life would be without clients!).  Is there a way (perhaps in the modules' .info files) to persuade the update manager not to check for updates for these modules?  EDIT  I'm aware of the project status url key that's available for the .info file so I guess I could set that to a non-existent URL but I'd much rather do this in a clean way if possible. Qt: Best practice for a single instance app protection How to re-link missing blender files I have multiple characters linked to a blender file, but i moved the original character files and now blender is sating they're missing.  Is it possible to get blender to find the missing blender files like it finds missing image files so that i can preserve the previously made animation?  On a side note is there a way to also view a list of all the missing files? Continuing example in Beamer What is the use of multiple main methods? Loop "Forgets" to Remove Some Items How do I address unchecked cast warnings? Probably dumb question, but I would like to ask it anyway.  I was to solve this equation:  $z^4 = -16$  At first glance, the way to solve it would be (as any other equation):  $z^2 = \sqrt{-1} * 4 \lor z^2 = -\sqrt{-1} * 4$  $z^2 = 4i \lor z^2 = -4i$  $z = 2\sqrt{i} \lor z = -2\sqrt{i} \lor z = 2i\sqrt{i} \lor z = -2i\sqrt{i}$  However, in suggested answers, there are $z_1, z_2, z_3$ and $z_4$ found using trigonometric formulas. Is there something particulary wrong in my solution and the only proper one uses trigonometric form of complex number? What exactly is a photon?

Is there a way to "source" bash.bashrc? In a related post, another user suggesting creating an alias for sudo with a space after it. Eg. alias sudo='sudo ' but there wasn't any context to this answer. Should I add this to my bashrc? Seems hackish.  What is the correct method for adding an alias for my sudo one-off commands? Which one is the formula of angular velocity? Is it $\omega= vr$? If not then why does the source below use $mvr=nh/2\pi$, where $mvr$ is angular momentum and $vr$ is angular velocity? Again $\omega=v/r$ shows radian per second. I saw $\omega= vr$ in one book and $\omega= v/r$ in another! I'm from Tunisia and I got a Schengen visa from the Austrian Embassy for  28 days, the “duration of stay”, and the number of entries is 1. But the validity of the visa is from 02/08/2015 to 13/09/2015.  Do I have to stay only 28 days, for example from 02/08/2015 to 29/08/2015 or can I stay there until 12/09/2015 ?  And if I have got to stay only 28 days, then can I choose the days of stay, that's mean can I stay in Austria for example from 09/08/2015 to 05/09/2015?
