I have my pc connected to a 17" monitor and a panasonic AE100 projector. I have an nvidia gforce 4 4600ti graphics card with 1 vga output and 1 DVI output. The problem I have is the picture on projector keeps dissapering for about 1 second at a time, this happens every 30 seconds or so. I have tried having the projector in the vga and the dvi output and there is no diffence and I have also tried having it as a single display and this also does not solve the problem. I have the latest drivers and tweeked the resolution to give me wide720 setting on the projector but the problem is also there using a native resolution. Any ideas on what I am doing wrong?
