Hey, gang. I just got my HR10-250, and I can only get an image with the output set to 480-I. On the two next settings (480-P and 720-P, I believe), I get two side-by-side images, and on the top one (1080-I), I can't even get that; my projector says out of sync range.

Equipment: HR10-250 feeding an RGB-Spectrum DTQ-100 doubler/tripler/quadrupler via component, in turn feeding an Electrohome Marquee 8500 CRT projector via RGB-HV. Where do I start?

Gratefully,

Look at the spec for your DTQ100. I suspect it won't accept these other inputs. You can't line-double an HD signal.

Okay, them what should I use to interface component to RGB?

Also, I'm not getting non-DD audio via the optical link. Ideas?

seems to me that your processor does not pass thru hi def over the component input.. it all has to do with kilohertz at the base level....

38.6khz or 38.8khz is 10801 from what i can remember your 480i is like 15khz then it gets processed

what kind of inputs does the processor have ......you might have to take component and convert to rgbhv and then set up projector to handle new input.

also what is the max khz of the projector? most good rgb projo's will scan 65khz and the great ones will scan over 100 khz

wow its been a long time since i did an rbh projo...man do i miss those

my 2 cents

Larry,
I have seen that on displays that will show HD.

You are already set up to take a 480i signal and upconvert it to a higher frequency, and your display it set to show that properly.

If you now send 480p to the converter, it will try to upconvert it, and will give you twice as many pixels again. That is why you get two images side by side.

You have to get that upconverter out of the path or turn it off or set it so it will only upconvert 480i, if there is such a setting. Your projector is set correctly, so there are not changes to make there.

A client who insisted on buying a boardroom projector over the internet a couple of years ago finally got HD cable, and was disappointed (boo hoo) to find that the component input of the projector could not display anything more than 480i via the component input. Well, it could show 480p, and 720p with 10% of the screen blanked at the left, and 1080i with about 20% blanked at the left...

The solution: Key Digital CTCA3 Component to VGA transcoder.

This took the component signal in and passed it through. He can look at a 480i signal on the component input if he wants to.

It also converts the signal to VGA (just a pinout change, not a frequency conversion), and has a VGA output for that reason.

Incidentally, it also has a VGA pass-through so that if a computer signal is present, it will go on to the display. I believe the presence of sync on the component input will switch away from the computer signal. This is an unbelievably elegant device and well worth it at $300.00.
A good answer is easier with a clear question giving the make and model of everything.
