The logo should only be displayed if you are wearing the headset.
It has a sensor to turn the display off when the headset is removed.
However, if you use the black plastic lens cover, it will cause the display to turn on because the sensor will detect the cover.
If you want to use the cover, then cut out the part that covers the sensor and that should allow the display to turn off.
I have had my headset on 24/7 for several months and no image burn-in yet.
