The lack of an instruction or false information given to customer shall constitute grounds to apply for a complaint because of nonconformity of goods with the contract. In accordance with the law, a customer can receive an instruction in non-paper form; lately graphic and electronic forms of the manuals, as well as instructional videos have been majorly used. A necessary precondition for this is the unmistakable, legible character of an instruction. What is an instruction?

Relatively obvious rainbow effect in video. The LV UST , for one, can throw a inch diagonal image with less than four inches between it and the screen. The connectors include an HDMI port for a computer or video source, one VGA port for a computer or component video, a second VGA port that works as either an input port for a computer or as a VGA passthrough port, both S-video and composite video inputs, and both inputs and an output for audio.
The other key setup issue is distance from the screen, with ultra-short throw projectors throwing a big image from a short distance by definition. At the native resolution, with the inch wide inch diagonal image we use for most testing, I measured the front of the projector at a bit less than 4 inches from the screen. As with all ultra short throw projectors, the actual projection distance is longer. The universal ultra short throw design to date at least gains some throw distance by putting the lens near the back of the projector.
The distance from the front to the mirror is a little over 11 inches, which gives a distance from mirror to screen in this case of about 15 inches. According to Canon, the full range of image sizes for the LV UST is from 60 to inches diagonally, with the mirror roughly 9 to 18 inches from the screen. At 9 inches, the projector would have to be mounted so the front extends about 2 inches behind the screen. Brightness, Image Quality, and Other Issues The LV UST is easily bright enough for the image size I used in my tests to stand up to the typical level of ambient light in most offices or classrooms.
More important, the projector also scored well on our standard set of DisplayMate tests for data image quality, with fully saturated color and no serious problems.
I saw a moderate issue with shadow detail details based on shading in dark areas , but only in scenes that tend to cause the problem. Skin tones were also a little yellowish in some scenes, but still on the edge of acceptable. The one potentially serious issue for video is a relatively obvious rainbow effect, with light areas breaking up into little red-green-blue rainbows when you shift your gaze or an object moves on screen.
This is always a potential problem for single-chip DLP projectors, but some show it more often than others. With video, however, they showed up often enough so that anyone who sees the rainbows easily, as I do, is likely to find them bothersome.
Also worth mention is the 3D-ready feature. As with all current data projectors, the 3D is highly limited, which in this case means it will work with a computer or with a video converter plugged into a Blu-ray player, but not with a Blu-ray player directly.
Ultimately, being 3D ready may help future proof the projector, but unless you have a definitive need for 3D, and the budget for it, you may never use the feature. One final plus is the audio system. The watt mono speaker offers reasonably high quality and enough volume for a mid-size conference room or classroom.
If you need stereo, you can plug an external system into the stereo audio output The relatively obvious rainbow artifacts in video make the Canon LV UST the wrong projector if you expect to use video extensively.
And in that case, the Canon LV UST, with its impressively high-quality data image and equally impressive ultra-short throw can be exactly the right choice. More Projector Reviews:.
