rainbow effect

Reviews A visual artefact that occurs in single-chip DLP displays, caused by the fact that the single DLP chip uses a colour wheel to create red, green and blue, and hence all colours. Occurs primarily when the eye looks across the screen or when adjacent...

Sony VPL-VW40 review

Reviews Even better, the outstanding sharpness isn't affected by any sort of video noise at all -- be it grain, dot crawl, scaling artefacts, motion blur or 'technology' issues such as DLP's rainbow effect or LCD's wire mess effect.

InFocus ScreenPlay 7205 review

Reviews InFocus has also implemented a new seven-segment colour wheel, with the promise of reduced rainbow issues. Everything looks so natural, and there's very little of the dreaded rainbow effect to be seen.

InFocus ScreenPlay 7210 review

Reviews Fan noise can be an issue -- the speed they turn at seems to change intermittently, which like the rainbow effect is only annoying once you notice it. Rainbow effect is minor but noticeable if you're looking for it, and the brightness level means...

Creative Zen Micro (5GB) review

Reviews It was only a matter of time before Creative improved upon its existing 4GB and 5GB MuVo2 line by releasing the Zen Micro, which is available in ten different colours -- twice as many as the iPod Mini's metallic rainbow.

Fujifilm FinePix Z20fd review

Reviews It comes in a rainbow of colours: light green, blue, pink, red, and black, all finished with silver accents. It's available now for around £100, with the price and the styling clearly aimed at the less demanding end of the market.

Sony NW-A1200 (8GB) review

Reviews It's a visual gem, coming in a rainbow of colours. Sony's 8GB NW-A1200 series is more or less identical to the 6GB NW-A1000. With an attractive design, good sound quality and some innovative firmware features, the A1200 should please those looking...

Dell 2300MP review

Reviews There are also noticeable traces of the dreaded rainbow effect (see 'Performance'), and the image size is very limited when the projector is less than 5m away from the wall (a quoted 0.625m image is possible from 1.2m away).

Cowon iAudio 6 (4GB) review

Reviews The new icon-based main-menu system is arranged in a slick rainbow curve, and the dedicated menu and volume buttons come in handy as you tackle the iAudio 6's array of features. The £190 iAudio 6, Cowon's first microdrive player, rivals most flash...

BenQ PE7700 review

Reviews The high-speed colour wheel employed in the projector minimises rainbow -- an anomaly inherent in DLP technology. The BenQ PE7700 is one of the latest hi-def DLP projectors to hit our shore. At the heart of the video display is the high-performance...

Sim2 HT3000E review

Reviews There's also no trace of the dotting noise over horizontal motion that plagues lesser DLP models, DLP's rainbow effect is remarkably well suppressed given how bright images get, motion looks crisp and sharp and perhaps best of all, the projector's...

projectiondesign Action! M20 review

Reviews But the M20 has plenty of other strings to its bow too, including really rich, deep black level response; lots of detail and sharpness when showing HD; and the suppression of almost all kinds of noise, including the rainbow effect and motion...

Rear-projection televisions

Reviews It's also a great price for its 52-inch screen size -- only the lack of Freeview tuner and occasional rainbow effects could be rectified with an updated model. All the fuss over flat-screen TV has taken the limelight away from the humble rear...

Planar PD7060 review

Reviews Otherwise, the only area where we might fault the PD7060's pictures is on its rainbow effect, as it's possible to see flashes of pure red, green and blue colour strips in your peripheral vision. While most brands are tending to pull out of the...

Sennheiser PXC 350 headphones review

Reviews The difference is akin to the difference between looking at a rainbow in colour and then in black and white -- although the sound still clearly exists, the overall feeling is a little dull and slightly washed out.
