Apparently the LCOS TV's are now here.

Someone please shed a little light (and please do not direct me to the endless, useless links on AVS forums that give no specifc scientific data, only boring opinions) on the differences between these 3 technologies, on a poor uneducated soul like my own.

I did a searchfor that model, and it is here... and I used Google for it....lol. And supposedly Toshiba has a model as well.
I also read somewhere in another forum that a nother company in Australia was staking surveys one their model which they would release this summer....

So apparently there are 100's of boot leg sellers of fake LCOS screens out there...
someone better warn the entire RPTV community of these forgeries...

So you can narrow down your research to LCD and DLP for the time being, if that helps any. ;)

And here is a review on the screen...

double bah, I rescind everything I said. They ARE out there, I know that. They're just not very readily available, was all. I don't know if you've tried shopping different models, but A.) There aren't many B.) Stock is very very very low.

bah.

I'd personally suggest staying away from the Philips LCOS units, at least for now. They've had some issues with that set.

That set is unconventional (as LCOS machines go) because it's a single chip piece. It uses a spinning prism, similar to the spinning colorwheel on DLP machines. Far fewer people see rainbows on these LCOS sets than with even with DLP machines with fast 5x colorwheels.

One amazing thing about the LCOS panel they're using is it's a 1ms response time panel, the first of its kind.

BTW, I don't know what they're talking about on ebay. It's not a 16:10 set, it's a true 720p native 16:9 set.

Here are a few picts I took from the 2003 CES show. Sorry about the quality, people were really crowding that booth.

Pixel Plus seemed to work reasonably well on poor quality feed. I was genuinely surprised. As with all of these kinds of technologies (ie. Samsung's DNiE), it seems to help some things, and add problems elsewhere.

Thankfully, you can turn it on and off though.

Here's an image of Samsung's technology working on splitscreen.

Way to bias that image... The only stuff on the right side is supposed to be out of focus anyway.

Actually, that was my fault. It was video material, and I snapped a lot of shots, but used a pretty bad digicam (and I suck at taking pictures). That was the clearest one that came out.

They did the same thing with PixelPlus, but there were way too many heads in the way.

Here's another shot. Take a look at the mountains in the back. You can start to see some of the problems with DNiE and sharpening effects.

The biggest question that I had was, "which is the best technology".
I want to buy a TV that will have as close to a sharp and clear picture as a Plasma screen would because I plan on connecting one of my computers to it for Video Gaming and watching downloaded anime and DVD's.

The LCOS looks nice, but not neccessarily cheap. I need some suggestions and some answers.

Like I said in a previous post, I spent and hour searching through AVS forum (yes I did read their FAQ's).

I have the funds now, so I would like to go ahead and purchase ASAP.

I am looking for optimal:
Brightness
Clarity
Sharpness
Viewing Angle (I do not current rear projection TV's that you have to sit down in front of, in order to watch them)...
DPI
HDTV

My understanding is that LCOS and DLP should look better than an equivalent Plasma screen being that they support greater resolution. I don't believe you can touch a Plasma with this resolution for under 5k (and probably much higher).

If you want a picture like what a plasma will give you, why not just get a plasma?

I have a 50" Samsung DLP.. I have a computer connected to it (RGB), as well as DVD player, DirecTV through DVI etc..

The Samsung has good display options for PC input. You can adjust the timing easily through the menu (they call it coarse and fine adjust), and the text from the PC is plenty clear enough to read. The actual size of the screen sort of makes you want to sit about 8-10 feet away tho.

I had the luxury of trying out every available set at Circuit City when I bought mine. I took a laptop and hooked it up to several, and the Samsung was the best projection Tv for PC input. Now if you want really good PC quality, a high def plasma panel (not ED) blows it away. Just remember that plasma will only last maybe 4 yrs at optimal brigtness. Panels in Circuit, even tho they are on every day all day and shut off at night, were dimming after one year of being on the floor.

I haven't gotten to try an LCOS set. I would definitely make really really sure it has a PC input, and that it can deal with PC resolution however. Lots of HDTV monitors don't do well with PC unless they have a specific input for it. The DVI input on a HDTV is not a PC input in most cases.. ie it will work but not as expected, and not necessarily very well.

you want more reviews (opinions), but don't want to visit the avsforums where all they discuss is audio and video and shed their opinions/reviews?

I will only say that I've been researching and looking for quite some time, and I am getting a 46" Samsung DLP this Saturday, hopefully....if the wife doesn't change her mind. :eek:
