Hey all, I was thinking about doing a simple LCD panel projector with a Sharp QA1800 or QA2500(800x600, 1024x7**, 16.7 million colors). I was wondering if it would be possible to get HDTV resolutions using component in to a Key Digital CTCA-2 which takes any 480P, 720P, or 1080i/540p input and displays it on a computer monitor through a VGA output.
I'm thinking about using my xbox, computer, and p-scan dvd player at high resolutions, I searched and I haven't seen anyone on these boards using this product but I was wondering if it would be a waste of money ( you can find these from 99 dollars to 199 dollars now). I'm just wieghing my options, thanks for any input!

It's just a transcoder (it converts component into RBG). There are many different ones available. I would check out avsforum to see which one is the best and the best deal.
I have the Viewsonic N6, which is a transcoder, a switcher, an NTSC line doubler, an NTSC tuner, and has the ability to overlay video over a computer source. It was expensive, and I don't reccomend it because it's only feature of any use is the transcoder part.

doesnt the line doubler always help?
--the fact that it outputs xga as opposed to most other transcoders that output into vga?

well actually, on a regular monotor, this is supposed to generate 480p, 720p, 1080i on a computer monitor, which means if you have an xbox or a really good dvd player, this device converts the high definition resolution to a monitor in the HDTV format, it doesn't line double, it is like a HDTV decoder. Computer monitors have better resolutions than HDTV's so they can easily display these formats. I was just wondering if it would work on a LCD screen, I don't see why it wouldn't.
If your lcd panel is only going to support 800x600 (XGA) you wont get true HDTV resolutions... period.
Just so you know 1080i is something like 1920x1080 resolution, I don't think and lcd exists that can do this, very few monitors can. I'm not sure but 480p or 780p may be displayable.
The thing that confuses me though is that Key Digital claims that this can do 1080i on a regular monitor, they probably have CRT displays in mind but I didn't think that monitors can produce interlaced pictures, I thought they were purely progressive.

Oh I know what it is. I was explaining that I have a transcoder as well, and that it also does other things. I use it for my Xbox.
Most transcoders (like mine) convert to a PC friendly output, like XGA or SXGA. However, it seems that this one outputs the same exact signal that it inputs. So it will output 720p or 1080i- not XGA, SXGA, WSXGA, etc. 99% of LCD monitors and projectors will not accept a 1080i signal. Some will accept 720p, but very few will actually display it at that quality.
For example, if you monitor has a max resolution of 1280x1024, it should accept 720p just fine. But chances are that it has a lower native resolution, so your not benefiting from it as much. This thing is too much money and not what your looking for. It seems like a veryt nice high quality product for people with high-def CRT's projectors (that takes an RBG signal). Not too useful for LCD or DLP.
Get a cheaper one that outputs regular computer (not HD) resolutions. You'll be able to feed it a 1080i or 720p signal, and actually select what resolution you want it to output (pick one that matches your monitor's native res). With the device your looking at, it seems you can't do that. It will only output whatever is input.
And if this is only for your Xbox, you can look into getting a VGA output cable for it. There are numerous threads about that.
Hey, thanks everyone for the replys. Lifter, would THIS be something like you were talking about, the XGA theater?
Also for anyone who is interested, I came across THIS Thread at hometheaterspot.com and apparently the new Samsung EDTV's are actually HDTV's with the 1080i turned off in the service menu, they just sell them at a much lower cost to get into a new niche...

Well, no. That thing doesn't accept component inputs.
Try this:

It's from the same company as the one you were looking at, it's a lot cheaper, and it does what you want.

The $8,400 IBM T221 has a native resolution of 3840x2400(QUXGA-W). There's a fair amount of LCDs can do 1080i, they're just realtively unkown and amazingly expensive.
as far as i know the only semi-affordable 1080i compatible panels are those from the dell inspiron 8100 laptops. they can be found for around 500 at lcd4less.com or some site like that (cant' remember the name) also, i fail to see how the xblaster is better than the n6 when i've seen the n6 for 180 and the xblaster is 200, the n6 comes with a remote and a line doubler and tv tuner...
oooh i take that back, i found the xblaster for 69 dollars here http://www.hometheaterworld.com/xblaskdcomto.html you could then get a normal xga line doubler/tv tuner (if ur after that)for about 70,(audioexchange?) and then you'd have all the functionality of the n6 for 40 dollars cheaper.
