We are installing an Epson EX 7700 Proj in our church (16 ft high). We connect with a 100ft HDMI boosted cable to back of church. Works fine with laptops. We want to use EX Worship software to manage songs, presentations, ....When we try to configure the system for Lenovo Desktop with Radeon 7700 board, monitor works, control panel display screen indicates "Epson JP", but no image (extended, duplicate, ....) is projected. Epson Projector indicates "no signal".AMD Catalyst detects Epson JP but again, no image.I have down loaded all drivers I can think of (Windows 7, AMD, monitors, ....). I have tried to update non-pnp monitor driver but can't find newest one (current is 2006). Any advise is welcome.
