Limited to maximum five units per order or transaction. Cannot be used with any other offer. Because the centre of a projected image is brighter than the corners, ANSI lumens is the most accurate representation of the image brightness.
ANSI lumens are calculated by dividing a square meter image into 9 equal rectangles, measuring the lux or brightness reading at the centre of each rectangle, and averaging these nine points. Contrast is just as important. This is especially important for home cinema applications. An average contrast ratio is about for LCD projectors, whilst some DLP projectors have contrast ratio of Keystone correction counteracts this effect by digitally compressing the image at the bottom or top, resulting in a squarer, more professional image.
Lamp Hours A standard lamp lasts for about hours of projecting. Projectors with higher lamp half lives are less likely to cause you a problem in the middle of a presentation when the projector gets older and used more, and generally represent better value per hour of use.
However, with all projectors a sharp knock can put the lamp out of action no matter how old it is. It is a highly reliable, all-digital display chip that delivers the best picture across a broad range of products, including large screen digital TVs, and projectors for business, home, professional venue and digital cinema.
This is how 3LCD technology works: white light is split into red, green, and blue using two mirrors that transmit light with a certain wavelength. Each colour is then passed through a dedicated LCD, before being combined with the other colors in a prism. The image is then ready to be projected onto the screen. Lens Shift Lens shift is generally a feature of high-end projectors or specialist home cinema models. This is a better method of producing a square image, rather than using keystone correction as the correction with lens shift is achieved optically rather than digitally resulting in no loss of quality Lens shift can also be useful for fine-tuning the position of the projected image on your screen Ratio In general, a ratio is a way of concisely showing the relationship between two quantities of something.
The most formal way of stating a ratio is by separating the two quantities with a colon :. A ratio is a comparison of two numbers. We generally separate the two numbers in the ratio with a colon :.
Suppose we want to write the ratio of 4 and 3. We can write this as common ratio for data or common ratio for video material Resolution The resolution is the accuracy of the image that the projector casts. Home cinema users - please note the majority of dedicated home cinema projectors project a native widescreen image and fall into one of three resolution categories - WVGA x pixels , WSVGA x pixels or WXGA x pixels.
Most projectors sold today are XGA. This is because most computers sold today are moving to XGA resolution as standard. Response Time The time it takes for a pixel to turn on and off. Response time is a good indication of how fast motion such as video or computer animation will appear on the projected image.
Weight Are you taking your projector on the road or leaving it in the board room? However, the desktop models still have more features and represent better value if the projector is going to stay in one place.
