which projector should I buy?

Q. I need a projector to show power point presentations as well as movies. I need to use the projector in day light as well as in closed rooms. I do not have a big budget. Could you please help in deciding which one to buy? Thanks in advance.


Answer
Projectors can be classified various ways (e.g. by primary use, by resolution, by technology). Almost all projectors will readily accept a computer input.

I'm not going to try to recommend a specific model since you need a brand/model locally available and supported.

You need one with emphasis on brightness, portability, and secondarily contrast ratio and resolution.

A low budget (prices start at about $500) precludes higher resolution projectors, and tends to push you toward a DLP based "business" projector. Given your wish to use it in a lighted location you also need brightness (2000 lumens minimum).

See the link for some popular choices. Prices will be in the $700+ range for most. Look at the lower resolution models first since they will be a bit less expensive. Note this sight has many reviews, a database of available projectors, information on projectors, etc.

Hope this helps.

DLP Projector color wheel malfunction?




chris m


:UPDATE:
I sent the projector to Optoma under warranty. I haven't been given a specific issue yet, however I did find out that it could be the electronics degrading due to overheating or the color wheel mechanism could be bad. There is a little wheel with Red Green Blue colors that spins in front of the lamp creating colors. It could be out of sync. Optoma told me that the projector can be sent to them for a cleaning every couple months for free, if under warranty.


ORIGINAL Q:
I have an Optoma 739 with about 800 hours on the first lamp. Recently after about 1hour of operation the image color begins to flicker and the image turns green. The projector is used in a smoking environment. What happened to the color wheel ; if it is that? And how can I prevent this in the future?



Answer
Projectors are not designed for smoking environments. I am quite surprised that Optoma is honoring yoru warranty. Most companies void the warranty, as they have "smoking" in the warranty statement.

The nicotine residue is sticky, which can clog the vents, filters, attract dust. This can cause the wheel to slow down. If the wheel slow down, that is one cause of the wheel going out of sync.

If you want projectors to work in a smoking environment, you need an enclosed box around it that can clean the air that is going in the projector.

I use to write repair manuals for projectors. The wheel out of sync would not cause the image to turn green, unless the wheel actually got stuck on green. A green image usually means there is an issue with the mainboard, which contains the video processor and controls the color wheel.

I would seriously suggest switching to an LCD projector. LCD projectors do not have any moving parts besides a fan.

Question about projectors?




DChem73


I would like to buy a projector. I would like to be able to play my ps3 on it and watch movies. Could someone educate me on how to spot a quality projector? What should I look for? Is there a quantifiable unit that describes how good a projector is. I'm looking in the 2000 dollar range.


Answer
Most projectors will allow you to play movies and your PS3, some important things to look for are: the connectivity, you should find one that has an HDMI input. This will let you get the best possible digital connection. Resolution, The higher, the better. 1080p projectors allow you to see full HD resolution at 1920 X 1080 pixels. Lumens, this is the measure of the output brightness, which is very important depending on the lighting in the room. If it is a bright room, then a higher lumens model will perform better. The higher the lumens number, the more light output you get. Refresh rate, Some projectors offer higher frame rates such as 120 or 240 Hz, which will improve the clarity when you are watching sports or playing your video games. You will also need to decide if you want a DLP or an LCD type. They both can offer excellent image quality, but create the colors and picture in different ways. I believe this is a personal preference and you should see both types for yourself. Take all of these factors into consideration in your purchase so you can get the maximum enjoyment from your investment. I hope this helps.

Answer
Do not get this one. I got it for christmas, and the picture is horrible. Also, it has to be like pitch black to see to get a picture. Also, it only has one way of hooking things up to it. Another bad thing about it is the fan. The fan on this projector is noisy. When I got this for christmas, within 5 days I stoped using it. The only thing is, you cant find a cheap projector that work's well. If you want my advice, check out this projector. LINK BELOW. It has a great amount of lumens. P.S lumens are what make your picture brighter, for if you use it during the day when there's a lot of lite in the room. Also it supports HDTV. But a lot of people say its for office use. E.X powerpoint, presentations. But it is pretty cheap, and is said to work pretty well. It's called the (Epson PowerLite 77c 2200 Lumen Multimedia Projector) Thats the one I might get. But if you want a really nice home theatre projector, than get the (Mitsubishi HC1500 720p DLP Home Theater Projector.)

Good luck, hope you find what your looking for.
