With regard to running the self test on dell display units which of these statements are true?

Once you disconnect the battery everything that is in your memories goes "poof" it will take a little time for all of your stations to come back. If I'm not mistaken you still have to set those manually. Radio is mostly satellite that's why you get song names etc. So drive let the computers collect data and before to long you'll get to see this names come up again. Hope this helps.

Your monitor should turn on without a source and display the floating 'Dell - self-test Feature Check' message. If it does not, verify the power LED is on "GREEN" and indicating either power on / diagnostics mode or "Amber" power saving mode. If neither indication you have power problems. If these symptoms do not apply, shine a light on the sceen and see if there is a faint image. If this is true, you have backlight problems.

-You should always refer to the user's guide or Manual for the display to interpret test results.
- you can use the self-test to determine if the problem originates with the display or somewhere else.

1.They include some kind of self test
2.You can use the OSD to change display characteristics of the unit.
