Found something interesting...... A couple of our friends had a problem with their Intel graphics cards not recognizing the Vivitek D912 Projector resolution (1920/1080) on their B9C software under printer management settings. If you have Intel HD Graphics family (Adapter type) and are showing a resolution of (1920/1080) in the desktop setting but not in the B9C software. This is how to solve the issue..... (I didn't connect to the printer. But steps are still the same).
Go to Screen resolution window (see below)
Select "Make text and other items larger or smaller"
Make sure the size of all items is all the way to smaller, and reboot your computer to apply the changes you have made.
