5. Start your flight and then hold Right ATL so the cursor changes to magnifying glass. Then move the screen to your unit.

6. If you have PFD and MFD, once you pop the units out they will be in one box. Please cleck on "+" sign inside the box to split them to two boxes

7. Once it's moved hold Left Alt and press Enter to get rid of header on top.

NOTE: If the PFD or MFD did not fill full screen, this is a weird MSFS bug. I found that it fill the screen differently when you resize it. Try not resizing the screen but just pop out, move, press ALT+ENT. If it doesn't work you can try to resize first and then ALT+ENT. 

Optional: You can also use the below addon to make MSFS remember your popout location

It's possible to adjust mapping if needed. You can open "\Community\flightsimbuilder-wasm\modules\pfd.cfg" (or mfd.cfg) and adjust the mapping command. 

For example, currently Heading Bug is updated by 3 degrees for one indent to enable appropriate response. However it might be desired to change it to one degree change, so the line below can be updated

3 degrees per one indent

button:6=(A:AUTOPILOT HEADING LOCK DIR, Degrees) 3 - dnor (>K:HEADING_BUG_SET) #HDG_INC

1 degree per one indent

button:6=(A:AUTOPILOT HEADING LOCK DIR, Degrees) 1 - dnor (>K:HEADING_BUG_SET) #HDG_INC

Save Position of G1000

To save position of the G1000 (so you don't have to pop them out every time), you can try this great utility https://flightsim.to/file/35759/msfs-pop-out-panel-manager

IV. X-Plane

2. Remove the bezel around GPS:

1. Download the following file G1000PFD_2d.png or G1000MFD_2d.png  (right click and select "Save Link As")
b. Locate "X-Plane 11\Resources\bitmaps\cockpit\EFIS\G1000" folder
c. Copy above two files  to the above folder. When asked, select "Overwrite files" 

d. Place downloaded files from above into "X-Plane 11\Resources\bitmaps\cockpit\EFIS\G1000" folder. 

X-Plane 12
1. Download the following no_bezel archive file and extract to your preferred location
b. Locate "X-Plane 12\Resources\bitmaps\cockpit\EFIS\G1000" folder
c. Copy all files from the archive to the above folder. When asked, select "Overwrite files" 

3. Launch X-Plane

4. Left click on G1000 in the sim

5. Click on top right corner to Undock it. The button on the top right corner is somewhat hidden but you can see it in the video.

6. Move the GPS to the unit screen

  

V. Additional functionality:

1. Power On / Off - Left <->
2. Switch from PFD to MFD - Right <->
3. LED brightness - Right Vol

4. LCD Menu Mode. Hold Click Left "Nav" for 3 seconds. 
4a (once in LCD Menu Mode). "NAV" press to Enter
4b (once in LCD Menu Mode). "NAV" small knob to +/- 
4c (once in LCD Menu Mode). "Baro" press to cycle through different video inputs (VGA->HDMI) "
4d (once in LCD Menu Mode). Right "COM" press to Exit LCD Menu Mode 

Once in flight simulator, you would just undock the GPS unit and move it to the unit screen.

4. Encoder Speed Mode. This will enable to increase / decrease encoder speed mode on a scale from 1 to 10 (by default it's 5). However currently, if you increase beyond 5, X-Plane / MSFS will not be able to read it.

Press and Hold "HDG" knob. The buttons will illuminate showing the current speed. 

Use "HDG" rotation to adjust encoder speed. 

Press "HDG" again to exit the encode speed mode.
