Thought I would add my $.02 to the iscan mini data pool. Previously, I've been posting in the Darbee thread, but thought this might be appropriate/helpful as well.
We have a Sharp Z30K DLP projector on a high cathedral ceiling mount (low earth orbit)...
In our HT set up, we have been using a Darbee for years, waiting for a full featured 4K DLP front projector to hit the market.
After reading several AVS posts about chaining together a Darbee and an iscan mini, a fellow AVSer (Thanks Blee) sent me one to try.
So, I got out the ladder and hooked up the iscan over (the projector). I experimented with several different combinations (mCable/Darbee/iscan) and finally settled on Darbee-->iscan-->Z30K (projector) sequence. I had issues with the scaling feature on the iscan (with DTV, it messed up the HDMI sync). So, I disabled the scaling and played around with the other settings. Like most things, I think it's a trade off... However, until we get to 4K, the added perceived detail/contrast is helpful, especially with HD Sports.
Initially, I was hampered by the line of sight limitations of the iscan mini IR remote control. So, I ordered an IR reciever extension (Monoprice) from Amazon. It plugged into the iscan mini and this allowed me to position the IR "eye" so that it could pick up a signal from the seating area. Over this weekend I further tweaked the settings and increased the Darbee from the level posted earlier.
I arrived at these:
55 Hi Def
Iscan Mini [version 1.03]
Scaler - Off
Recall - Low
Mosquito NR - Low
SD Smoothing - Low
Detail - 6
Edge - 2
Ringing Suppression - High
Output Smoothing - Low
Hope it helps someone...
