I just won the Proxima 920+ on Ebay and will be getting it soon.
But I think if this NEC monitor works out, it will be far better than in quality and price.
For one, it has much higher contrast ratio.
And it's less than half of what the Proxima costs ( $550).
The grand total for the NEC set-up, everything together should come out under $600.
May I ask again: does anyone have actual hands-on experience on this LCD?
My brother owns the 1550v, but I am afraid to mess it up because it wasn't my money.
Thanks.

I'm 90% sure that the 1550 has the LG xxxxx07 in it, where as the 1545 has the LG xxxxx05. They are practically identical where as the only difference is the contrast ratio. Taking it apart is the same as the the 1545. But be warned, I'm only 90% sure.
hey lifter
sorry for taking so long to reply but ive ben real busy with work
ok now to the good stuff u asked how i secured the fresnel i just cut the origonal mounts a bit mainly the small one so it wouldnt obstruct the lcd ,what i did was cut the top off where it used to hold the stage glass, and on the large mount all i did was remove 1 of the black hinge brackets so i can remove the top completly
at any time . there is also a long metal strip in the rear of the cover i has 3 slots cut out i removed it and bent the 2 outside peices flat to hold one end of the fresnel.
as for flipping the ohp the heat isue is still there i still need a fan to cool mine and i only have a 410w bulb i also flipped mine to go rear projection so i didnt need to use software to corect the image but nvidia has a program called nvrotate it comes in the newest drivers.
and i dont know why but when i remove the ground to the 2 h&v boards my lcd flickers constantly.
btw nice projector u got there 😉 looks like a sweet picture im gonna have to check out that movie .
i finished construction on my projector now i have to set it up somewhere dont have much room

Hey lifter, since you are kinda the resident expert with this panel now, you said you have a friend with a CRT sony.
Rating the sony as a 10. How would you compare your set-up(1-10,1 being the lowest, 10 being the highest) to his for
-DVD's
-Tv watching
-games
-General productivity apps(web browsing, word, excel)
thanks very much too.

Hey cruser, all the thanks goes to you. I broke my first panel. Thanks to you, I was successful with my second. I would have never thought to remove the to glass and make a compartment for the panel in the OHP.
Thanks also goes to YWH who really helped silence all the naysayers.
AJ, it's really hard to give a rating on each of those things. I mean there are so many factors to include. Some people can't stand a screen door effect, others don't really notice it. Some people really notice higher contrast ratios, and some don't. Some people might give the projector an extra 4 points simply because it's bigger. It's pretty apples and oranges.
Here's the situation
DVD's on my friend's TV (using a prog. scan DVD player) look very nice. I believe his TV had the comb filter and the reverse telicine going on.
DVD's on my system look great too. Color-wise, it's exactly the same. His black levels are a bit nicer, but no LCD, no matter how good, can compete w/ the black levels of a CRT. Mine is just fine for me (300:1). I watched Black Hawk Down yesterday (a movie with lots of shadows and fast motion). It looked great. Really great.
My friend's projector has no visable screen door effect. CRT's generally have a very high resolution, so any pixelation is from the source (whether it be TV or DVD).
My projector has a noticable screen door, and the ring effects from the fresnel, but the image is twice as big as my friend's, so you could argue that it cancels that out. The screen door effect on mine is not bad at all. MUCH better than my friend's Sharp projector (800x600 native res). The ring effect is a bit of a problem for me right now, but I'm working on it. Like I said before, I'm going to try mounting the fresnel closer to the bulb and further away from the LCD. Maybe that will do something.
Brightness is not a factor. If anything, mine is brighter than my friend's $3000 TV. My 575W 11,000 lumen MH bulb gets the job done very nicely.
My friend's TV has a much weaker viewing angle. The image fades when watching from even a 45 degree angle. I have no viewing angle restrictions. I can look at it from an 89 degree angle and still see everything just as brightly.
I cannot speculate on gaming. My friend had a PS2 plugged into his composite input and it looked like garbage. There is no PC input for his TV (although if he wanted, I imagine he could get an RGB to component adapter), so I couldn't comment on computer games.
I just ordered the expensive Viewsonic N6, so I should have some component inputs for my Xbox shortly. I'll keep everyone updated on that. I haven't played any computer games yet, because my projector is hooked up to a cheapo Celeron PC w nothing more than it's on-board graphics card. I'll try Unreal II w/ my bro's P4/Geforce 4 machine this weekend.
As far as TV goes, my friend has a crappy Adelphia digital cable service (digital, meaning you can see digital artifacts badly- I know because it's what I have). All a nice TV does for NTSC is highlight how crappy it is. Basically, all the flaws of analog TV are more visable. At least a cheapo TV has a large scanline effect to disguise the poor signal.
I have the same cable service, and I have not hooked it up to my projector yet (I will when I get my N6).
Why my friend bought a $3000 HDTV and did not get Directv is beyond me. I told him that the whole point of having an HDTV is to actually watch HDTV signals (we live in southern california, so recieving over-the-air signals is out of the question). He's not very bright when it comes to electronics, so I don't think he understands what HDTV is (I even told him that it looks BETTER than DVD's, and he still doesn't get it). Personally, I will eventually get Directv when I can afford it. I don't really need it until football season starts again.
All and all, if I can eliminate the ring effect (actually, it's more like a "giant fingerprints" effect), and fix up my screen (didn't do a great job of painting it) I think I've got a SUPERIOR viewing device than my friend. Once I get a SXGA+ or UXGA panel w/ a 400:1 CR or better, there won't be any question.

Hey Lifter, you've probably answered this already, probably even to me. But forgive me, I don't listen well 🙄
Anyhoo, screen door. Compared to a retail LCD projector with a native res of 1024x768, how is the screen door? More? EXACTLY the same? Or Less?
They have at my school a Proxima Ultralight S540, which has 400:1 contrast ratio, 1024x768 native res, and a manual image size and focus lens. A great projector in my opinion. And I haven't noticed any screen door at all. So is this the same as a lcd monitor and I'm just not noticing the screen door?
Also, on that topic, the lens on the projector at school intrigues me, how could I make, or could I buy a lens that not only focuses but also allows picture size to be changed without moving the projector back and forth?
Thanks
Lifter
" I'm going to try mounting the fresnel closer to the bulb and further away from the LCD. Maybe that will do something."
I've found that moving the LCD farther away from the fresnel increases screen door effect. I built a small box to support my laptop panel on top of my 3M 9550 (with 2 tiny super quiet squirell cage fans to cool) This box put's my LCD 2 inchs above the stage glass, now I have noticeable screen door. Earlier I had the LCD only 1/2 inch above the stage and had next to no noticeable screen door. Once I have time I wil rebuild this assembly to lower the LCD back as close as I can to the stage.

hi cruser !
add a lens into lenses of project, the lens is a myopic lens(-50*)
and drive up the system of lamp(reflect, lamp, focus lens) about 2~4CM.drive up the lenses of project about 5~15CM at th same time.
than, the image of four angles will be better,light
ya know after reading about the OHP and thinkin about trying to create a Grand wega Rear projection television I am starting to seriously think if I will be able to even get a sliver of the quality produced by that TV.
I mean all a grand wega is though is a LCD that is projected into a mirror. The comments made about the rings and the screen door effect are starting to make me wonder if this would be worth it for me. I am going for quality of a grand wega II. I think it might be obtainable but I am not certain.

Well guys i sold my projector today and im on to a new one.
btw $750 for a $450 investment + time aint bad .So can anyone tell me whare to purchase a ultra sharp 15" 1600x1200 pannel
and compatable controller i seen a viper 2 controller that looked nice but cant find where to buy it
AJ
i dont know what to say to you ,if you are looking for a grand wega you should buy a grand wega. these projectors are not costing thousands to make for under $500 you will have a screen that will make you fall off your chair cause you feel like your in the game!! or at the theater . the circular rings lifter is talking about has to be a bad fresnel i have none of those rings
and for the screen door with an image of 100" if i sit 4'-5' away its nonexistent. I came to this fourm after gettin SMOKED on the 100" tv thing . after 2 weeks of reading i was ready ,and WOW i am verry impresed with the results from my first project . I had to sell my projector to my friend just to get him off my back, and dont use the pictures on this fourm to conclude what to expect cause its MUCH better quality than the pictures show.
My sugestion to you is get a 1600X1200 400:1 contrast ratio pannel + controller and a metal halide projector and if that dosent KNOCK YOUR SOX OFF then sell it ,you should have no problem gettn your money back ,and then you will know for sure if you can match the quality of that tv .
any ways heres another pic

Cruser your projector look's great , you worked for every
cent.
And you made a friend really really happy I bet.
Hope when I build one it look's half that good......

Cruser,
thanks for giving me that info. The lines and the screen door effect were really concerning me. I am gonna go back to the drawing board and figure this out a little bit more. I need to keep following my saying
"If someone can build and sell something, I can build it better and cheaper then them."

Cruser, good job on actually making profit. Hopefully you won't be stuck giving lifetime tech support to your friend 🙂. As far as the Dell Ultrasharp, there are only a handful of UXGA controllers out there. As you probably already know, all of them are meant for large quantity industry orders (basically, for people who build and sell LCD monitors and projectors).
Digitalview does sell individual controllers through allamerican.com - but they charge a hefty fee for it. The SV-1600 is $685, and the SVP-1600 is $640. Both support UXGA, and the only difference is that the slightly more expensive one will control plasma TV's.
The really attractive thing about the digiview controllers is that they have an IR port on them, and sell a remote w/ TONS of features. Another plus is that you can choose NOT to fill the screen when you lower the resolution. That would allow you to lower the resolution and not have to worry about having a big enough fresnel. It's also easy to switch to and from 16:9.
The bad thing is the controller's component inputs do not support HDTV- only NTSC and PAL. Another bad thing is that it has no DVI input. Personally, I'd almost require this for that kind of money. I'm using two VGA cables to reach my projector and I can notice degradation in the signal.
Personally, I don't think the Dell/Digitalview plan is even close to worth it at this point. For a while now, it has been my long term plan, but I'm scrapping the idea. It'd cost $1000 minimum.
When I was in Office Max, I noticed a Viewsonic LCD moniter. It was 15", great viewing angle, 1280x1024, and had a 500:1 contrast ratio. They were selling it for $499. To me, that thing is a far better value than paying $600 on a Dell panel and $700 on a controller.
I think we'll see UXGA LCD monitors soon enough, and the contrast ratio of these things will keep getting better and better.

No, I didn't even buy it. I don't remember what model number it was. But I just went through Viewsonic's website and they don't have ANY moniters boasting those specs. I guess Office Max got carried away. There was a moniter that had a 450:1 CR w/ XGA native, and SXGA max (that was probably the one I was looking at). So forget I mentioned it.
OK Lifter, Thank's for the reply.
I looked on the viewsonic website before I asked you.
Office Max and stores like that print mistakes like that sometimes.
I'm still probbably going to go with the NEC1545v or the I-O DATA A15v.
