All the problems is with the laptop settings check your laptop settings, display res set to a larger size than the projector can handle, check the FN+F8 keys you must hold the FN key down and press F8 or the key that show CRT/LCD
FN function F8 Display settings
1 click laptop display only
2 click external display only
3 click both display on
Projectors are dumb terminals it only show what is coming from the display card.
There is no software installed in any projector
