Vivitek H9080FD Review
April 5, 2010 By Geoffrey Morrison
LED will set you free
Its claim to fame, though, is not its size or aesthetics, but its light source. Three little LEDs—making all the light needed to fill your big screen.
In the past, front projectors have used a lamp (a fancy light bulb) to create the light needed for the DLP or other technology to create an image.
These lamps were expensive, hot and only put out white light. Single-chip DLP designs, like the H9080FD, used a color wheel to filter the light so you could see a full-color image. There was a significant loss of light with a color wheel, as well as the oft-discussed and occasionally noticed "rainbows" that came with sequential color.
By using red, green and blue LEDs , all of these problems can be addressed. More light makes it to the screen without having to pass though a color filter, so less energy is wasted. The LEDs themselves are more efficient. Those combine for less power required to run. Color is still created sequentially, which is to say the image is created with all the red information, then the green and then the blue.
It's done so fast that your eye/brain combines it to see everything at once. It’s done much faster than with a color wheel, so it's pretty much impossible anyone will see rainbows.
Then there's the color itself. On paper, if you have accurate color points with one display, it will perfectly match a different display. In fact, this is ideal. You want the colors to match what the editors edited to, and the directors wanted for their movie/shows. Of course, it's never that simple.
What surprised me was how much more realistic the colors were on the H9080FD—some of the most realistic colors I've ever seen on a display of any technology. In measuring the color points, red and blue were pretty much spot on. Green was a little greenish blue and grass and leaves looked a little off. But it was more than that, more than the measurements can tell you. Colors across the entire spectrum were more vibrant, more real. There seemed to be more subtle gradations between shades. The difference in skin tones suddenly became much more noticeable. Fine differences between lip shades stood out.
Colors popped more than they did on other displays I've seen. For a color junkie like myself, this was flat out extraordinary. Accurate color is awesome, but accurate and vibrant color is even better. And for the record, this was with "Brilliant Color" turned off and Color Gamut and Color Space set to either REC709 or Auto.
This is one of the first video technologies I've seen in years that I would actually recommend making th...
