yeah, I have connected first DVI to monitor, then have disconnected dvi cable from monitor, have used dvi-to-hdmi adapter and have connected it to LCD TV (actually trough yamaha a/v reciever hdmi). Then, I have Disconnected LCD TV, removed dvi-to-hdmi adapter, disconnected power, added 2 modules of RAM, connected power, connected first dvi to monitor and since then, there is no picture on first dvi! Second dvi is working fine. Monitor is Samsung 22" and drivers are latest from ASUS (tried with latest on ATI, too). I haven't flip the switch!! Do you think that might help?
