Need some help here...
I've got my 4308 hookup up via HDMI to a Pioneer 5070...no problems. I then tried hooking up the other HDMI monitor output to my Optoma H31 via a DVI-HDMI adapter (note to others...you can't plug a DVI->HDMI adapter directly into the receiver with another HDMI cable connected next to it...not enough room - get an 8" M/F HDMI pigtail from monoprice to work around this).
Problem is that I can't get the rcvr and H31 to sync (with or without the Pio turned on). My monitor output is set to Auto (both), and I've tried the 2 scaling variants as well as turning off scaling - no luck.
Also, to note on something others mentioned earlier about switching times when changing between SD/HD channels: I've got a SA8300 DVR cable box fed into the receiver via HDMI. When I switch between SD/SD, SD/HD, or HD/HD it takes about 1.5 seconds to switch. The receiver HDMI scaling/resolution were set to their defaults (scaling enabled, auto resolution, etc.)
