This works for all PMDG 737 aircrafts

How do I install?

Simply find your PMDG B73X folders, go to your Community folder and look for: pmdg-aircraft-736\html_ui\Pages\VCockpit\Instruments\PMDGTablet

and select what ever PMDG Aircraft you have installed and click on for example:

pmdg-737-600\Assets 

Then replace the file called "pmdg_tablet_home_bg" with this one.

I strongly recommend you back up the original icons and wallpaper from the assets folder before you replace them.
