In mirroring mode, both screens need to use the same resolution. The external display probably can't support the huge 2880x1800, so it's lowering yours to match.
In System Preferences > Displays > Arrangement tab, uncheck the mirroring option. Then you should see two separate preferences windows, allowing you to set different resolutions for each display. ...

You can indeed use both the HDMI and Thunderbolt ports to drive two separate monitors with a Mac Mini.
Any Mac with a Thunderbolt port can use any mini Displayport display, cable or adapter, so you're correct that the mDP to DVI adapter is what you need1. If you have a display that requires dual-link DVI (typically only monitors with resolutions higher than ...

Hold down the command and option keys while clicking the display
icon
Next locate the screen adjustments on the external monitor and you
will notice now there is an option called "Rotation".
Choose 90 Degrees and now your ...

You might use ⇧⌘4 (Save picture of selected area as a file) and just drag the selection around one display.
screencapture -m only captures the main display:
-m Only capture the main monitor, undefined if -i is set.
I don't know if -S supposed to capture the display of the selected window, but options like -Sw or -SW only seemed to capture the ...

It may be easier to use the "Sleep" option in the menu (upper, right). It sounds like the "clamshell mode" you're talking about is actually "Sleep mode" to the computer. I believe that this is the most effective way to get things into "sleep mode."
Other options:
Setup a "hot corner" that puts everything to sleep.
Use keyboard commands for sleep. ...

I'm guessing the 2nd display is not an Apple display.
I believe what is happening is that the display is, in fact, going to sleep, but in such a way that the Mac thinks it has been powered off.
Replacing the HDMI --> DVI converter with an Apple Thunderbolt --> DVI converter is your best bet at fixing this.

I have the same MBP. It only has a single displayport/thunderbolt output, which can drive a single monitor. The only way for it to drive multiple external displays is to use a daisy chained Thunderbolt display, or an adapter that drives multiple displays from a single input (Matrox makes one) or possibly a usb driven adapter.

That adapter will work fine. I have used the regular DVI → Composite/S-Video adapter (M9267G) many times on many different Macs.
Contrary to what has been mentioned in the comments, it is not an active adapter; it requires no external power, and PAL/NTSC resolution can be output from the iMac's graphics card. It behaves exactly as any other second screen ...

So, I tend to use Chrome for JavaScript app development, but since around version 15/17 (or there about), its not been possible to open the debugger console in a separate window in a two monitor development environment. Thing is, if you open Safari 6.0.4 (and maybe earlier) and you show the developer console, there is an option to 'detach into separate ...

Yo. I've tried with every possible scenario. I found a note on Apple's site somewhere that stated that only one tb monitor is allowed for use in windows 7. So... Until they update the drivers for Win7 you can't get it working. However... If you use a TB Imac and add a second monitor to it, that does work as I have that setup at home.

I found an easy way around this and I hope it helps people. I tried resetting the NVRAM and it did not help. I am pretty sure it is due to flaw in the OS upgrade.
Here is the fix. Set up video so that when you move to the top left corner, the video shuts off. When you come out of sleep, if the resolution is low, move the mouse to the top left to shut ...

Applications like Sidekick or ControlPlane allow you to change settings (network, desktop picture, custom terminal actions) based on location evidences (geolocation, attached devices...etc).
I'm sure you will be able to use one of those to detect you are at your desk with your 27" plugged in and run a command disabling auto-hide.
