Is there any lcds out there that have true hd and come in the 15" range. True Hd projection is running in the $5000 range. If someone was to find an lcd...then take it apart and use it with an Overhead Projector it could save thousands of dollars. Lets see what you experts have to say...
So nobody wants to reply hunh...i heard samsung is realeasing a 7.1" lcd that can output true hd...i just need some support with my project...i wanna build a 1080p projector...so come on people help me out
Honestly, a DIY projector is really just more trouble than it's worth anymore people. I'm running a Dell 2300MP (1024x768) and I love it, even during the day. I have a 72 inch wide projector screen mounted to the wall and have the projector in the coffee table for nearly a 100 inch diag 4:3 picture. Wide format stuff comes in just over 80 inches I think. I also have a 200+ inch screen that I roll down from a pipe close to the ceiling for when I have company over of just want to get into the theatre mood a little more. *smile* Point is, this 1024x768 projector was only one thousand dollars and is DLP and works great out of the box. It's beautiful and easy, and it isn't a fortune. I don't have any HD source video though (I'm sorry, but I'm not a sports fan so it's just not worth the money yet to wait for actual HD content across the board) but if I did, you simply get the next model up for 3 thousand (1400 x 1024) and you're only 40 pixels away from actual 1080. You can't tell me that that's not close enough, and it's not THAT bad compared to the 5 or 10 grand sets out there for much smaller pictures. 40 inches? 50 inches? you're kidding, right? Don't settle for anything less than 100. 100 inch daily screen for a grand, I just don't see how you can beat that. Remember that DVDs are only 720x480 so don't kill yourself for all the HD setup if you don't actually have all the HD source material. And if you do... then if you can afford all that, then you shouldn't have any problem with a 3 thousand dollar projector, c'mon now.
sorry to burst ur bubble buddy but 1024x768 on 100inch really sucks. considering 720p=1280x720 and 1080p=1920x1080 which is nearly double the pixels..at 100+ inches u can see big diffrences...Jonjandran built a wuxga pj...it does 1920x1200...a projector like that under 2grand + a ps3 with true 1080p output or xbox with the $200 hd dvd...is well under $3000.
Well don't worry about bursting my bubble, I'm looking at my screen every day and loving it. My Dell 2300MP DLP projector works wonderfully. I can post pictures if you like, but we all know pictures of screens don't really do them justice. I'm not talking theory, I'm relaying my experience. I'm not trying to insult, I'm just tired of some people pushing the idea that unless you've got a 1080 display you might as well be watching a VHS on a handheld black and white TV. Keep in mind like I said above, I don't have any 1080 input sources. I've only seen 1080 in other people's houses and I'm sorry, but while the sports stadium full of fans at a game was beautiful (I could see the fans freckles), nothing else (normal tv shows) was any different than any run of the mill TV because the input source material does not carry the same quality. The $5,000 Plasma next door with the $200 a month cable bill showed the same crappy compressed version of 24 that I watched on mine. Yet mine was more than twice the size and a third the cost. Yes 1080 is 'much better' by the numbers but until you have a video source coming in that is broadcast at 1080 that was recorded at 1080 then you're lying to yourself if you think having a 1080 display is doing you any good. Especially if we're talking about cost benefit. If we're talking videophille stuff, then all bets are off, it's no longer a conversation about reality, it's about subjective ego trips with no verifiable data. But that's not what this post is about. Just like I said above, consider your source and that should be your rule. If you, like me, watch DVDs and satellite TV of programming other than sports, then at the present time there is absolutely no benefit to a 1080 display. At best, the source coming in is being upsampled and therefore breaking the point. A 1080 display has more and smaller pixels, yes, but stretching a 320x240 4:3 image to 1080 is just ugly regardless of your display. I don't care if your pixels are the best in the world. A 320x240 image stretched to fill your screen will have artifacts and/or be blurry regardless of how good your display is. A great display still can't add detail where none exists. As for seeing pixels at 100 inches, I don't know what example you've looked at (maybe a 640x480 DIY setup), but unless I walk up to my screen close enough to touch it, the pixels are not perceptable. Even from 5-6 ft they dissapear, much less 15-20 ft or so which is where a medium to large sized living room would put you. Yes, you can see my pixels if you really want to. You've got to pause the video and stand within 5 ft of the screen, but you can see them if you try. I can see the pixels on every 1080 display I've looked at too if I'm that close and that hard up to prove a point. But actually watching content on 720 vs 1080 from a normal viewing distance is no different when your source content is coming in at 240 or 480. And just as a reminder, my projector is 1024x768. An 800x600 projector produces a MUCH more noticable crosshatch pattern even at 20 feet away regardless of the image size. After all of this though, lets get back to the point of the thread. The poster was trying to save money by puting together the cheapest 1080 display possible, and wanting to do it with a DIY projector. My point was simply that if you're pinching pennies then you won't have a true HD input source so why are you trying to have a true HD display? Better to spend your money and time on the best quality display you can than to focus on resolution alone. In the sub $3000 world, you'll get a MUCH better viewing experience if you don't kill yourself trying to get a 1080 display and instead focus on contrast ratios and image fidelity. Secondly, my point was that comercially available projectors like the Dell 2300MP (now 2400MP) produce a beautiful image and come in under $1200. Perfect for a low budget, and they come pre-assymbled. The moment all of the content I watch is not only broadcast on an HD channel, but CAPTURED in HD with HD cameras, I'll start to consider an HD projector. But the $5000 mark won't be the entry point by then. We'll be much closer to a 2 or 3 thousand dollar 1080 projector by then, and that's plenty affordable. And one last thought. We're SOO focused on HD resolution here, YET we're talking about a DIY projector based on an LCD panel on an overhead?? Lets say you get the resolution you want, your color depth, contrast, and image fidelity are WAY out of whack in that setup. All our talk about resolution is completly moot at that point because you basiclly throw all image quality measures out the window except for resolution. Much like a 5 MegaPixel camera phone, it's not all about the pixels.
You my friend are one confused dude. Whoever said anything about not having a 1080p source for my projector. In my recent project, I have decided to build a full 1080p projector using a Dell WUXGA Laptop. When I first posted here, I wanted people to recommend 1080p lcds that they thought may be good candidates for a home build but you blasted away with your opinions of 1080p. Unfortunately your opinion is not needed, although if you think you can suggest a better lcd screen then by all means go fot it. And while you're at dell.com I would suggest you check the price tag on the 1080p projecter they are reselling for Optoma...$6744.05...cough cough. PS: If u reply to this then you're most certainly gay. Make sure u keep looking at ur screen every day. Cause u never know when ur gonna have to replace ur lamp anyway.
Sorry if I came off as insulting, That was not my intention. You're right that my take on 1080 wasn't asked for or needed. I was just surprised at the focus on 1080 while planning a DIY projector. I have yet to see a DIY projector come within 50 percent of looking as good as factory built stuff just because of the contrast issue with blasting high light through an LCD that wasn't made for that. If yours is beautiful then congrats. It'll be the first I've ever known to be beautiful. What I was talking about for the lack of 1080 input sources wasn't whatever cable signal you pay for, but the source video itself. Until the shows you watch are recorded with 1080 cameras, then a 1080 display isn't doing you any good. That's all I was trying to say. And as of now, Feb 07, very few shows are actually recorded in 1080 other than sports. Everything else on your HD channel is being scalled up from SD recordings and that's not doing you any good from a quality standpoint. Lastly though, I don't know what projectors you've ever actually used, but bulbs do not die randomly. They die pretty close to a set time frame (usually 2000 hours) and start to get dim hundreds of hours before they die. And every projector has a counter so you can see their lifecount down. I just replaced my bulb this week actually. It was at 1800 hours after 2 years of using it and while it hadn't died I figured I'd replace it and keep the used bulb around just in case. Yes the bulb was $300. $300 is a small number however for 2 whole years of daily TV watching.
@razehsani: Can you tell me how you'll connect the Dell laptop LCD screen to a 1080p video source thru HDMI - for example a PS3?
Head over to lumenlab.com/forums somtime and read up atm im building a 1080p+ projector and as far as getting HDMI imputs and such to a laptop screen there are a few choices I picked up a board/controller for a WUXGA samsung lcd 15.4" with HDMI, VGA, 2-YPbPr, S-video, CVBS, 2-Rca, and TV Tuner and IS HDCP compliant.. YOU need this for a PS3 to work in 1080p and or blu ray or HD dvd's Controller board http://stores.miva.com/express/merchant.mvc?Screen=PLST&Store_Code=manhattanlcd and as far as dont look as good as comercial projectors????? not true with a proper setup and at $15-50 depending on what build you pick beats the hell out of $300+++ for a comercial bulb... + 1080p Com Projectors run near $3000+
