I tried to connect my AE700 to my PC with a 20m (lindy) HDMI cable (with a DVI adaptor). The good news is it works, 1280x720, but there is pretty bad noise visible in dark picture areas (blue scintillating dots). This noise pretty much disappears if I lower the resolution, but it makes having a digital connection a bit useless. I guessing this means that the signal strength is just not strong enough to push 720p bandwidth through 20m of cable. Is there anything else it could be, I've tried connecting the projector and PC to a common earth, but no luck. Just thought I'd ask before putting the 20m cable up for sale on ebay and ordering a 10m one.
