Hi, I connected a Sony SDM-V72W called a Personal Entertainment Display to my Sony Viao Laptop computer System Model PCG-R505ES(UC). I want a larger screen then the one I have with my laptop. My husband uploaded the CD, connected the cables from the Screen to the laptop and plugged it in to the wall socket. However, when we start the laptop, the external screen doesn't start up. Does anyone know if this can be done and how? Thanks so much :upset:
