Please help… in desperate need of advice for displaying on a 42″ LCD
First of all, thanks for reading my post!
Here’s the deal. We are opening a new multi-media studio. The plan is to display finished videos via front row (as quicktime movies) on 5 42″ LCD’s on the walls. (Sharp Aquos). The TV’s are 1080p so of course I realize that our standard def. stuff isn’t going to look fabulous on them, but it looks worse than horrible. I’m trying to figure out how ti fix this so they at least get up to the “horrible” level! The same video looks 100x better on a DVD (although it still doesn’t look great) which is weird since you’d think the original quicktime file would play much better since it isn’t compressed. Because we are constantly going to be loading new media onto these screens, we have hooked up a mac mini w/a DVI to HDMI connector to each LCD, so the signal going in is great. The actual desktop of Mac OS looks incredibly sharp and amazing! I’m wondering if I can somehow convert the signal to analog (RCA) if it would help. Or maybe component? I don’t really want to go this route as it a) defeats the purpose and b) is expensive. Any advice you can give would make my week… no… my year!!! Thanks in advance!

Many of those screens have pretty poor de-interlacers. I’d try to de-interlace the footage you feed to 1080p with the help of FieldsKit (there is a demo at http://www.revisionfx.com ) and see if that helps.
Apart from that: which resolution is reported back to the Mini by that screen? Sometimes you get weird values there and I’ve seen Acer’s that were reported back as interlaced (!), so the Mac tried to compensate for that and it looked awful.
Don’t give up, you’ll get there. We get excellent quality feeding a Sony Ruby with a Mini in 1080p via DVI.

I was helping out on a production and the LCD monitor they had looked great when fed a component signal. Looked terrible when fed an SVHS (Y/C) signal. Could have been a faulty cable. But that’s something to consider.

This video will look like crap on the Sharp. Period. If you can get it to 720p or 1080i you might have a better chance. Next issue is that these sets are some of the worst out there. To make matters worse they have internal noise reduction. You need to try to go into the settings for the screens and play with their default settings. Turn most of the “helpers” off and see if things don’t improve a little. Unfortunately in my experience, even hi-def video looks cartoonish on these screens – even at their best. If you have the budget, you might look into some of the Silicon Optix high-end home theater video boxes. These are using Teranex software for scaling, NR, deinterlacing, etc. and might be able to do a better job of conversion for these screens than the internal circuitry.
