Limitations

Brightness and Uniformity: Our sample XJ-A250 missed its brightness rating of 3,000 lumens by a wide margin. The highest brightness we could achieve was in Eco Off mode set to Bright and Color Balance set to Normal. Still, the reading was only 1,850 lumens after 15 minutes of warm up time. Immediately after power-on, the lumen reading was as high as 2200, but there was a 16% drop in brightness within the first 15 minutes of operation. Typically, projectors with UHP lamps get incrementally brighter as they warm up to a stable operating temperature, but this one dims down somewhat.

Unlike most projectors, the XJ-A250 has three brightness settings: Eco Off, Eco, and Save. However, the Theater, Game, and other preset modes can only be selected in Eco or Save mode, not when the XJ-A250 is at its brightest. In Eco mode, the Standard preset put up 1,300 lumens, Theater and Graphics both delivered 970 lumens, and Game mode came in at 1,035 lumens. With Eco Off mode, you can choose between two brightness levels (Normal and Bright), but remember that presets are not available at these settings. Save mode dropped brightness levels by 33% from Eco mode (to 880 lumens), and fan noise all but disappeared.

Light Loss after Keystone. All projectors lose some light and resolution when keystone adjustments are used to square up an image, simply because a portion of the imaging chip is turned off to create the effect. If you plan to use this projector in a mobile fashion and place it on a conference table, tilting it up and using the auto keystone will be the normal mode of operation. When uptilted and keystone corrected, the unit loses about 20% of the light it would otherwise deliver. In other words, the 1850 lumens one gets in its brightest mode drops to about 1500.

Image Quality: Data images from the XJ-A250 were sharp from edge to edge, but their color saturation was low and the images looked a little flat. Reducing brightness and raising contrast helped, but the images still lacked the pop one sees on competing models.

Saturation, tint, and sharpness adjustments were only available for composite video. Adjusting image color for signals other than composite video required using the RGB Color Balance sub-menu, and the impact on the image was subtle at best.

Another distraction most noticeable on computer data images was a green bias on the right edge of the image. This was prominent when the lens was set to wide angle, but disappeared when the lens was zoomed to its maximum telephoto position.

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.
