I am connecting a PLV-Z4(w/hdmi port)projector to a PC nvidia 7800 GTX card (w/DVI-I port). When I connected with a HDMI-A to DVI-D it only allowed 2 displays 800x600 and 1024x768(this one constantly flickered, both looked terrible). I wondering if I upgrade the caple to DVI-D DUAL Link to HDMI-A that might help. Honestly I have no idea but I'm pretty sure that if I keep it digital(hdmi, dvi-d) and not analog(vga, dvi-a) I'll get a better pic. I have a 25 to 30 foot distance to cover. Any one know bout this, or where I can find the best cable for this? Appreciate any help!
