+ Affordable purchasing price
+ Low maintenance costs (low power consumption)
+ Mobility (Beamer has cigarette format)
+ No fan noise (passive cooling)
+ Long service life of LED
Disadvantages:
- Low intensity
- Fixed Focal Length
- No trapezoid effect equalization
- Slight 'jaggies' in DVD movies, due to low resolution
- 2 USB ports are required, otherwise the light intensity decreases significantly (hence two USB extension cable Order, if required)
Self-test:
The software installation was both WinXP and Win7 (here first the driver on the manufacturer's website to download and pre-install) without any problems.
The tripod included served its purpose and allows for quick and easy positioning of the projector.
Vivid's main shortcoming is its low light intensity, which decreases continuously with increasing the screen diagonal (naturally).
This means that with film renderings in 50 '' format - even when absolutely dark environment - the brightness and contrast must be massively increased, resulting in a restriction of the color spectrum and thus to a noticeable degradation of image quality (projection was here, however, only a wall).
A completely acceptable image quality is obtained - my subjective opinion - only with screen sizes less than 30 '"and completely dark place, because you come here with significantly more moderate settings of brightness and contrast to considerable color modes (projection was here a' paper screen ', in short, , the projection surfaces are still expandable in any case, which I consider the purchase of a high-performance screen for this projector as inappropriate).
Ambient lighting is immediately fatal noticeable due to the extremely low light intensity. In 'dim' rooms must therefore the screen size to be significantly reduced under 20 ', which generally provides the use of a video projector in question (so I do not think really useful device for presentations).
Conclusion:
Who can guarantee a completely dark environment, with about 30 '' screen diagonal (equivalent to approximately 75 cm and requires a distance of about 120 cm from the screen) satisfied, on occasional 'away looks jagged edges' in DVD movies and not excessively huge demands on color brilliance, can strike without hesitation.
