I've used with a two year old RP1 through a passive HDMI-DVI cable a monitor with DVI connector (Iiyama AS4316UT). That worked fine.
Now I can use a slightly bigger monitor (Iiyama E485S) but that doesn't work: no signal. Strange is that when I first connect the AS4316 (all works OK) and then without restarting the E485S all keeps working.
It looks like the old monitor gives a signal like "ï'm connected" an the newer does not.
Any suggestions? Thanks
