Untuned -

Welcome and good luck -- the folks here are fantastic and you are going to have a lot of fun and will like the results. I have a machine with lesser capabilities and am super happy. They are all right on the throw distance. I found doing everything for the setup as a mock walk-through was helpful; you'll need to iterate the steps anyway and with repetition will learn....lord knows I still am!

BTW, others on here could tell you if the "sweet spot" on your PJ is 720p or 1080i. 1080i looks better than 720p on mine, for example.

Also, if you watch much 4:3 content, you might consider setting up raster and image on entire tube face. You can use removable/adjustable black material to cover the white parts of the screen for 16:9 or other AR content. There are posts for how people have done this, though I don't bother. I chose letterboxed 16:9 and full-size 4:3 over 16:9 (at same size) and smaller, pillarboxed, 4:3 content. I don't know if there are discussions on this somewhere or not...just me.

Bests,
Matt

Thanks Matt for your encouragement! I have been very pleased with the response from the crowd here. They are very helpful and very active. My setup is not complete, but nearly done. The final throw distance is 106" for an 80" width screen. Still less than I had been planning, but not nearly as much as I thought when I started the thread.

It's interesting you mention 4:3 vs 16:9. I wondered how I should set up the pj (raster etc) since the screen I have is 4:3, but I intend to only watch widescreen material. Anyway, nothing stops me from setting a new signal entry and calibrating for 4:3. Maybe I can consider that once I finish setting up one signal. I'm having some challenges converging the red on the green, but other than that I expect to be able to watch my first movie on it this weekend!

I think I read somewhere that you are using an Iscan HD processor; how are you set up with it? I have one also, in fact I have two, but one will be for sale shortly.

Dan -

Sorry to let this go. Did you get it all hooked up? What is your progress?

My iScanHD power supply died very shortly after I got it. My freaking $80 OEM replacement PS arrived last Friday and tonight I hope to get it going. Actually, your plans for using it really raised my eyebrows. I feel very sheepish to admit this, but somehow I had it in my mind that HDCP would force my PC and BR player to output all analog signals at below 720p or 1080i. As such, I bought an HD Fury 3 to take and switch HDMI from my BR player and HTPC. The iScan HD was just for laserdiscs (yes, I watch them still) and SVHS (I don't, but I never know what I might come across at a flea market).

If you are right and my equipment outputs as does yours, I might run everything through the iScan as well. That would look like:

Oppo BDP [component output fed in @ 1080i]
LD and SVHS [composite x2]
HTPC [RGBHV via HDF3, just at 1024x768]

Any idea if I can pump all that out through the iScan's analog out/passthrough port?

cheers,
matt

I originally picked up the iScan HD because I realized I would need to convert to RGBHV, and looking at prices for even component to RGBHV converters, buying the iScan made sense. HDCP was mysterious for me too, and only when I realized that it would be problematic that I learned more about it.

Anyway, my Samsung BD-C6500 will output 1080i and 720p from the component out with HD material, but will not upconvert SD material. It will upconvert SD material, but only through the HDMI port. No problem, I thought, I'll run the component out into the iScan; SD will be upconverted, and HD will passthrough. Works for SD, but not HD. Since 720p and 1080i is not processed, it goes out the iScan the way it came in - YPbPr colorspace. The simplest solution, since I have only one source at this point, would be the HDFury: I would set a fixed 720p output from the Samsung via HDMI, and HDFury would convert to RGBHV, then I would not need the iScan. Somewhere along the way, I read that gamma boost would be interesting, and an RTC2200 came up for sale that I bought. I can use it to convert component to RGBHV or just have RGBHV passthrough. I have yet to pick it up at the border, so I have not tested it yet. I think my set-up will look like this:

Samsung (component-out) to iScan HD (component-in, analog output set to YPbPr colorspace) to RTC2200 (component-in converting to RGBHV) to Projector.

That way, I can add sources, like a Wii or Xbox or whatever, and have constant output via the iScan all the while adding gamma boost.

For your setup, I suppose you would do the following:

Oppo and HTPC (HDMI) to HDFury (RGBHV output) to iScan (vga input = analog passthrough); LD player and SVHS with composite outputs to iScan will be processed to the signal of your choice, output RGBHV. This way, you have just one cable going to the pj, the iScan acts as a switcher, only processing material from your non-HD sources. It should work, although I would think you should set the HTPC to have the same output as the Oppo, unless you have a signal input in the pj just for that.

Let me know how it goes!

Dan
