Hi, I'm new to home theater setup. I got an old Faroudja vp401 line quadrupler and all input and outputs work and tested fine. I am trying to connect it to an Infocus DLP projector but the video shows a lot of horizontal lines. The 401 works well with the with my vga computer monitor. VP 401 outputs are RGBHV and VGA 15pin. Infoucus had M1 input. I have a vga to M1 cable that works fine from computer to projector but does not work with faroudja vga to the projector. Any advice or help.
