Can I watch Blu Ray on a Projector with VGA input?

I just bought a Vivatek D825MS DLP projector for cheap off of amazon. It is 1080i capable but I'm running into some problems. I also bought a new Blu Ray Player that has a HDMI output. I bought a HDMI to VGA adapter cable and you guessed it...my education begins. It dosn't work. So, after some research I am finding HDMI has the HDCP protection crap built in and there is a digital to analog conversion problem as well. The only solution seems to be devices such as the HDFury1 that is basically a $100 box that converts HDMI(digital) or DVI(digital) to VGA(analog) with a chip and some circuitry.

Question 1. Am I right in assuming I need a $100 adapter to make this work?

Question 2. Has anyone tried the $100 adapters and do they work?

Thanks for any help.

That box or anything similar is your only choice...and I still wouldn't be 100% that it would work with a Blu-ray player. As long as you get it from a place that will honor returns without additional costs...you can give it a try.

Otherwise, there's no way you're getting an HDMI to VGA connection through any simple adapter device.

Besides...while this projector accepts 1080i input signals, it's limited to 800x600 native resolution display so you're not getting any HD in the end...period.

If you're going to buy a Blu-ray player...you might as well commit to an actual HD display. The Vivatek was cheap because it's not an HD projector!

What resolution does 1080i need to display properly?

And what is the highest pixel rate (if that's the proper term for 480,720,1080) 800X600 can support?

Thanks for the input.

Sorry for the dumb question..720, 1080 ect ARE resolution ratings therefore a 1080i vertical resolution signal will be rescaled to 600 vertical resolution with this projector...right?

I think I got it now. The difference I will see with the $100 adapter will be the difference from 480 vertical resolution which is a standard DVD up to 600 vertical resolution which is far short of real HD which is 1080 vertical resolution...right?

So in this circumstance the picture will only be about 20 percent better than standard DVD after I spend the 100 bucks, instead of the more than 100 percent better I would get with a projector having 1080 native resolution.

Probably the best way to get the best resolution would be to use a laptop with VGA cable and a HD video program like Power DVD that supports MPEG4 or HD or whatever...more research to do.

Yes. And not a dumb question. ;)

Pretty much. Except real HD starts at 720.

Yes and no. For sources that are native at 720p or higher they should look marginally better than DVD. But for sources such as DVD (from a traditional DVD player) or SDTV (Standard Def TV), they may or may not look better depending on how well the projector upscales. If you play DVD's on your Blu-Ray player, then the picture might or might not look better than a regular DVD player. I say this because with a Blu-Ray player, it will upscale the DVD, but then the projector is going to downscale it. That's a lot of digital processing and then digital to analog processing on top of it (HDMI to VGA). To me, there's too many chances of introducing artifacts and noise into the picture that shouldn't be there.

Probably the best way to get the best resolution would be to use a laptop with VGA cable and a HD video program like Power DVD that supports MPEG4 or HD or whatever...more research to do.

Again, no matter what your source, your projector will still only output at its native resolution. Just want to make sure you're not expecting HD levels of resolution by going with that option. :)

:haha: Im sorry but I always have to laugh when I hear someone bought a "HDMI to VGA Cable" But I can understand someone making that mistake if they are new to this. To answer your first question, no you don't need to spend $100 to make it work. Below is a site where you can get it for Less than $70 bucks. I've tried this one and others and yes they do work very well, particularly this one because it works with most manufacturer brands.
