Casio XJ-A250 Mobile Projector

Allan Abbott, March 8, 2011

Advantages

Throw Distance Flexibility: The XJ-A250's powered 2:1 zoom gives you a lot of projection distance variation for a particular image size. For example, to project a 100" diagonal 16:10 image, you can place the projector anywhere from just under 8 feet to almost 16 feet from the screen. The zoom movement is very smooth and hitting your mark is easy.

Though the 2x zoom can be handy, at the maximum telephoto setting light output is reduced by 21% compared to its brightness potential at maximum wide angle. This is relatively little light loss compared to most 2x zoom lenses. However, since the projector already falls short of its lumen spec, using the telephoto end of the zoom may cause a further curtailing of light that is not desirable (see Brightness and Uniformity).

Illumination System Life: Lamp life for mobile projectors is generally in the 3,000-4,000 hour range in normal mode, but the XJ-A250's laser/LED light source is billed as having a prospective life of 20,000 hours. That would let you give a 4-hour presentation every day, five days a week, for about 20 years. If you plan to use your projector extensively, this can save you the cost of replacement lamps.

Powered Focus: Unlike most mobile projectors, the XJ-A250 has a powered focus ring. Just touch one of the two focus buttons on the remote, and your image will focus in seconds. The control operates smoothly, and overshoot is minimal.

Brightness uniformity. Brightness uniformity was much better than average at just over 87% with the center of the image slightly brighter than the perimeter.

Quick start/stop: Casio's new illumination system does not require the usual warm-up and cool-down times of traditional high-pressure lamps. On applying power, the XJ-A250 is up to full brightness in less than 10 seconds, and when it is time to shut down, you can pack up the projector immediately after you hit the power switch.

Warranty Provisions: Casio offers a 3-year warranty on the projector and a 3-year or 6,000-hour warranty on the laser/LCD illumination system.

Maintenance: Like most DLP projectors, the XJ-A250 has no air filter, but an occasional cleaning of the air intake vents with a small vacuum cleaner is recommended.

The only reason to purchase this projector is for the lack of need to purchase a bulb. Otherwise stay away. Why? 1) Technical support from Casio is non existent. Give the manual to an 8 year old and voila you have their technical support. 2) If you are teaching a technical program where you need to see EVERYTHING on the screen, you will need to use the cords. You can't see some things on the screen when you use WIFI ie: tool tips and some menus. 3) You can't use WIFI to explore the internet if using the WIFI to connect to your laptop. It needs it to work. In my opinion if, I had to do it all over again, I would just get the cheapest brand of this brand because the WIFI feature isn't all that.

I bought the 240 a couple of weeks ago to use as a bedroom tv. If it lasts close to the 20,000 hours I'll be happy. I'm watching the nba playoffs right now from about 8 feet away on about an 80 inch screen. I can't imagine ever going back to a regular tv. A 40 or 50 inch screen wouldn't do it for me any more.

I hope projectors get to the place where they sell at high enough volume to get really good and cheap. This one actually looks fine for sports and most casual viewing but it wouldn't be competitive as a strictly home theater projector. It also has a couple annoying things - you have to resize and refocus the image every time you turn it on. It takes 30 seconds and is already second nature but it's not ideal. I've had projectors for a while, this is my 4th in the last 10 years and this is the first one I've bought to use as a regular tv. If 20,000 hours is true it's maintenance free for my purposes. The extreme portability and huge picture trump the ability to watch in bright light and somewhat better picture of a panel.

I love this projector. I'm a sales trainer and keynote speaker and work in both large and small venues. First of all, this is the easiest projector I've ever used when it comes to set up. Just turn it on and in seconds you've got a full bright image and the keystone and focus kick in to adjust the picture perfectly. The zoom feature really allows you to project a huge image from a short distance, so in my opinion this is much better than going for a "short throw" unit because it give you tremendous flexibility - you can operate from pretty much any distance. I've read all the reviews and I know there has been much discussion about the Casio not meeting it's stated lumen output, but all I can say (since I don't have the ability to measure) is that I got a beautiful bright picture in a fully lit conference room. And here's what I loved the most, the Light Source doesn't produce a ton of heat. The fan does cool the unit but on conventional projectors (both DLP and LCD) with regular bulbs, they are just plain hot. When working in a small room full of people, I find myself constantly losing the battle to control room temp because all my previous projectors were kicking out so much heat. Not with this baby .... it stays cool to the touch and the fan output is like a gentle warm (not hot) breeze, which means I can keep a comfortable environment for all us, including me when I'm dancing around the front of the room doing my thing. With ease of setup, crisp bright images, and cool operation, this thin light projector is this road warriors new best friend.
