Can someone tell me how to fix my projector? Connected by HDMI, it worked well with my laptop (Windows 8). But then, i was getting tired of duplicating the displays of both the laptop and projector, I set the projection screen of my laptop to "second screen only," and then the projector displayed "invalid format." Can someone help me, please? Answers are most appreciated.
