i was looking at an HD projector that costs 900-1000 but was wondering if it would be better or equal to an LCD HDTV of a similar price. i will be using it for watching TV and movies. i will have it in a somewhat dark room and use a grey projector screen. unless a white screen would be better. would i be better off getting a 50″ lcd tv or would the 100″ projector screen make it worth it? here’s some info on the projector:
The Optima HD20 operates at a native 1080p resolution (1920 x 1080 pixels), while it also is compatible with most computer formats, such as UXGA, WXGA, SXGA+, SXGA, XGA, SVGA, VGA resized, VESA, PC and Macintosh It can also accept common global video inputs and video formats up to 1080p (HDTV, EDTV, SDTV, NTSC, PAL, SECAM). Like all Optoma projectors, the DLP engine operates without filters, keeping ownership and maintenance costs low while ensuring consistent performance throughout the projector’s life. The projection lamp is rated to last up to 4000 hours in standard mode or 3000 hours in bright mode. The HD20 also incorporates a rapid shutdown feature that further reduces ownership costs, and it comes with a one-year parts and labor warranty, with the lamp being covered for 90 days.

I am looking into getting one of these three 720P DLP Projectors and I will need to upgrade my tuner to handle HD. First off, which of these two projectors would you go with? Would you recommend another? I’m not ready for 1080P yet so not interested in one of those. Secondly, I don’t know much about tuners, so what would you recommend for me? Here are the three I’m looking at:
Mitsubishi HD1000U High Definition 720p DLP $1,260
Optoma HD65 720p DLP $680
Mitsubishi HC1600 720p DLP $660
Any other tips or recommendations? I’m going from a rear projection tv to an overhead projector? Thanks.
The reason I’d rather not get 1080P; more $, I’d have to buy a pricey blueray player plus blueray discs and I’d also have to upgrade my dish to HD which is too much

With the price of large (>32”) LCD displays decreasing rapidly and new functionalities being added to LCD displays, does it still make sense for businesses to buy a projector vs. an LCD display?
Some of the variables to consider when evaluating this question are product quality, price, picture quality, screen size and other such considerations. We discuss these and other factors from a typical business organization perspective. Read other articles and make your informed judgement.
Product Life: LCD TVs or displays typically have a backlight life of 30,000 to 60,000 hours (ie, if you have the display on for ~6 hours every day, the backlight will last for 16 years). Even then the backlight can be replaced in most LCD displays. A projector bulb typically has a life of 2,000 hours.
Price Considerations: A basic projector can be found for INR 25,000. However, if the projector is going to be used for video conferencing or board room presentation, a high resolution, good contrast ratio and saturated colour projector would be required. The cost of such a projector is close to INR 1 lakh. Thereafter, you need to factor in the prices of projector bulb and projection screens. A typical projector bulb needs to be replaced almost every year or two with bulbs costing Rs 20,000+ per bulb. We have added these costs over a five-year period to compare a projector vs. an LCD (see chart below). With 46” LCD TV or display costing around Rs 135,000 – Rs 150,000 and dropping, price becomes less of an issue when considering whether to buy a Projector or LCD display
Figure: Total Cost of Ownership Comparison for Projector vs. LCD Display
Basic Device capital cost for projector is INR 70,000 and that of an LCD display is INR 150,000, Projector Screen Capital Cost (Wall Mount Screens INR 5-15K) is INR 10,000, Consumable cost of the projector is 20,000 x 3 = INR 60,000, Consumable life of a projector is 2,000hrs and that of an LCD display is 60,000hrs and the Cost of Ownership of a projector is Rs.140, 000/- and Rs.150, 000/- for an LCD display.
Assume: 5years of usage @ 5hrs a day ~ 6600hrs of use. This translates to 4 lamps in 5 years requiring the customer to buy 3 lamps in addition to 1 supplied with machine.
What is clear from the above figure is that a Full High Definition 46” LCD Display is, at best, only marginally costlier than a XGA Projector of ~2500AL. Additional costs of low screen installation costs and lower device loss costs are purely additional.
Picture Quality: Projectors such as a DLP or LCD projector use glass panels to combine red, green and blue colours to create the image. When sitting close to screen, the viewer can see the different colours at the borders of an image, aptly described as the rainbow effect. The rainbow effect takes away from the image quality and can give headaches. High-end projectors have been able to reduce the rainbow effect, however the problem still remains and these high-end projectors cost more. LCD TV or LCD displays do not have rainbow effect issues and the quality of the picture is good at close range.
Rather, projectors cannot compare with the picture quality for an LCD display. The vividness of the colours, the contrast ratio, the colour saturation and image sharpness are much better for an LCD display than a projector. When viewing a projector image, especially in ambient light, the viewer has to dim the lights or close the curtains unless the business has purchased an even more costly higher lumen projector. Not true with LCD displays, as the brightness and colour quality are much better.
Viewing angles used to be an issue with LCD displays but this issue is no longer true. Most LCD displays can be viewed from up to 176 degrees.
Dead or Stuck Pixels: Projectors can suffer from dead pixels and LCD displays can suffer from stuck pixels. Both dead pixels and stuck pixels result in white spots in the projected image. However, the manufacturers of both technologies have worked hard to minimize such issues and in most cases they provide warranty against such issues.
Screen Size: A common thought is that screen size is not an issue for most projectors as the thinking is that the projector image can be made larger by moving the projector away from the screen. This is not true as the image quality deteriorates as the image becomes larger. With projectors, most buyers opt for maximum optimized projector image sizes from 76-inches to 120-inches and the actual working normal projection image used is much smaller. Today, if businesses need a large LCD display in the maximum projector image size, a wide variety of competitive LCD displays can be found in this range.
Portability: Projectors are easy to carry and move around. For a business this could be a value-add or a drawback. LCD displays are durable and can be moved however they are not as light as projectors.
Power Consumption: Projector power consumption varies more from unit to unit, with brighter conference projectors requiring more power than smaller portable projectors. It is hard to compare the two technologies on this performance parameter.
Connectivity: Most LCD displays have more number and different types of ports than projectors. As a result more types of devices can be connected to an LCD display than a projector.
Other Value-Add Features: New features are appearing in LCD displays that could be quite valuable for businesses. For example, touch screen features on LCD displays allow for LCD displays to be used as digital whiteboards where the data written on the display can easily get captured electronically in a text document.

Digital projectors are those video projectors which are used in conferences for presentations. The digital projectors receive video signals from, usually, desktop computers and display images on large screens which can be easily comprehended by all in the gathering.
Two Types of Digital Projectors
To begin with, there are two technologies used by digital projectors, the older one being the LCD, liquid crystal display with independent transparent panels of LCD for each constituent primary color (red, blue and green.) The image transmission depends on the signal received by the projector from PC which redirects the light signals through these LCD panels and lens onto a screen. The LCD projectors look pretty similar to older slide projectors and are simple in construction and thus cost less in comparison to their successors DLP projectors. The LCD can be thought of as slides placed at the focal length of the lens making it complete. Clarity of picture in LCD projectors depends on the number of pixels it is set for. (Pixels are smallest area of data or picture holders)
DLP Projectors: The Latest of the Digital Projectors
Digital Light Processing or DLP is a technology developed by Texas Instruments in 1987. DLP projectors bring in a paradigm difference in technology in image projection to board rooms. Unlike their predecessors, DLP projectors make use of tiny mirrors or micro mirrors to reflect light images to pass through the projector lens and onto a screen. Each mirror can be thought of as representing a pixel. The mirrors reflect primary colors in rapidly rotating succession as actuated by a rotating color filter wheel. The image of rapidly changing colors ‘constructs’ images for human eye perception. The micro mirrors are collectively called as DMD or ‘digital micromirror device’.
For the sake of enhancing picture clarity, the rotating wheel is provided with a plain patch which allows plain white light. This type of DMD projectors are also known as single chip projectors. The three chip projectors are a bit complicated but offer better clarity. Here a prism splits the light from lamp into primary colors which are redirected to DMD which recombines them before projecting through the lens.
Where Is the Difference
DLP projectors are lighter and give far better pictures. Single chip resolves 16.7 colors while the three chip model does a, hold your breath, 35 trillion colors.
Commercial Models
Texas Instruments is the pioneer who owns the patent for DLP technology. Fraunhofer Institute of Dresden of Germany developed the same technology simultaneously and markets it as Spatial Light Modulators. HP, Samsung are other market leaders in both LCD and DLP technologies.

I have about $300-$400 to spend on a used TV. There are great deals on craigslist. This would go in a bedroom, I have lots of space in this layout so that’s not an issue. I already have a smaller 42″ TV with 1080p, so I don’t care about that much quality, I just want something HUGE, over 42″, to play halo and hook up to my computer. Which is better for what I want?

I have a projection screen tv that does not work anymore. from what I can tell, the projectors are fine and the problem lies with the TV itself. Is there a way to take these projectors from my TV and make a projector that I can attach to say, a DVD player and then project that image onto one of those pull down screens?
