Is a home theater projector a good choice?




Dutch D


I'm planning on putting a projector with an approximately 106in screen in my room. This projector will be used mainly(maybe only) for my xbox360. Is this a good choice? Are there any major issues with projectors?


Answer
Projectors can be a very cost effective way to get a huge screen, however there are several factors when deciding to use a projector. The main ones are the size of the room and how many windows are in it. If you have a small room with a lot of light the picture will look fuzzy, even if it is hi def.

As a general rule of thumb sit at least 1.5 times the distance of the size of the screen. If there is a lot of windows and/or light hitting the screen get a projector with at LEAST 2500 lumens, if not more. Also cover the windows with light nullifying curtains and turn off lights if possible for a better picture.

Don't just get a cheap screen. Use this link to decide the type of screen to get. This can greatly effect the picture quality:

Hope this helps and remember you will also need a nice sound system to go with it because its not hi def without hi def sound. I recommend Klipsch.

Home theater projectors?




assassinat


Hi All!

I'm looking to buy a home theater projector and get off of television once and for all.

I'm looking to spend about $1000, and a used one is ok. I'm looking for quality of picture, how well it works with the lights on, and reliability.

Thanks!



Answer
In general projectors -- like most TVs -- give the best picture in a dark/dim room. If you leave lights on contrast suffers and the "pop" is reduced. That said, bright projectors (which unfortunately also mean you risk shorter lamp life) will work (particularly with a suitable screen) to give a good picture even in a moderately bright room.

I commend you on proposing to replace your TV as the primary display --- it's the best way by far to get a big picture and get an overall movie (or HDTV) watching experience that can even beat a movie theatre. Although ... it's worth noting that keeping a small TV is probably advisable for watching the news or things that don't warrant turning on a projector.

This is because lamps in projectors do wear out (Typically they last 3-4000 hrs) and cost $300 or so to replace. The life of the lamp is maximized if on/off cycles are minimized (particularly short cycles and if the lamp isn't allowed to cool properly). See the 1st link on maximizing lamp life.

Now to projectors. Since needs vary widely I'm going to reference a list of recommended home theatre projectors (2nd link). Many are outside your price point, but there are some that fit your budget. Do some reading on this (and other sites, such as projectorreviews.com) to learn more before you make a decision.

Hope this helps.

Good used projector for around $350-$400?




coltsfan82


I need a projector to put in my room, i need it to be HD, also i need it to have HD ports to plug an xbox 360 into the projector. Please put links to the projector. Thanks !


Answer
You need to go online to ebay and see if you can find one. Keep in mind that projectors needs a dark room and the lamps only last about 2,000 hours of use. The cost of the lamp can start at $50 to $300 each. They also no not have any sound capability, so you will need a sound system. I use a projector for watching blu ray disc movies only. You might be better off buying an LCD tv from Samsung or Panasonic, which should last you around 60,000 to 100,000 hours. Hope this will help you out.

What LED (portable) Projector?




Faddi A.


::::Someones Experience::::

Well Iâve concluded after a lot of search that LED projector should atleast be 60 lumens, 500-1 to 1000-1 contrast and should have USB or SD card slot. LED projectors brightness level is somewhat better than the conventional lamp based projectors so anything in the range of 100 lumens in enough. Also the biggest advantage of 20000 to 30000 life hours :-D I am now a happy owner of 'Samsungs sp-p410m' LED projector which is absolutely brilliant. Couldnât find it online in UK so ordered one from Korea :p yep i liked it that much :p it has SVGA 800 x 600 resolution, brightness 170ANSI, 1000-1 contrast ratio and 80 inch projection which looks stunningly bright, vivid and crisp on my not so white wall. oh and it has digital keystone correction too :-D inputs are VGA, composite & USB. its around 750$ but worth the money as it will last for 10 to 15 years. I recommend following in order, but plz give specs a LONG good look:

1-Samsung sp-p410m
2-Benq gp1
3-Toshiba TDP-F10
5-Samsung sp-400
4-Acer K10
Please give your suggestions or share your experience.

Thanks

Led projectors are very dim... the dimmest on the market. Only useful in a very dark room, & small screen. Resolution is no better than DVD resolution or worse on most of them, except the most expensive.

Led projectors are nowhere near as bright as the dimmest lamp-based projectors. Typical popular normal projectors boast 1600-4200 lumens with a contrast ratio of 2000:1.

LED projectors are 10-60 lumens... About the brightness of a very dim penlight flashlight, & very poor contrast ratios. Brighter ones are just now coming out, but still not good or bright enough to be practical.

For the price, you can get a 1600-2700 lumen DLP projector with a 2000:1 contast ratio. They're small enough to fit at least 2 in 1 backpack.

I typically fit 2 small DVD players, mixer, a laptop, & 1 of my DLP projectors in a backpack.

LED projectors are a portable novelty or toy for those with a disposable income, & not really very useful or practical yet. Wait a few years for the technology to get better.

From my experience with super bright LEDs, & the specs on them, is they grow dimmer with age long before their "lifetime" is up. How useful will that dim overpriced projector be if it's grown too dim to barely be seen after 3,000-5,000 hours?

Notice the LED display on your alarm clock, DVD player or VCR has grown too dim in just a few years?
