Vivitek D537W DLP Projector Review
Not a top choice for home theater connoisseurs, but it gets the job done.
The Vivitek D537W gets plenty bright, but the modes that offer more color accuracy are significantly dimmer.
While the Vivitek D537W doesn't quite match up to the peak brightness of the ViewSonic PJD6531w, it's admirably close, topping out at 2855 cd/m2.
Like most projectors, there are several user modes on the Vivitek D537W, and they have a huge impact on the brightness output. As you might expect from the name, the Bright mode has a brightest whites, and we scored these sections based on its performance in this mode. However, bright modes like this typically throw the color performance under the bus, so understand that there's a time and a place for each mode that's largely dependent on the ambient lighting in the room. The most color-accurate mode, which was our calibrated User mode, has a drastically lower peak brightness.
The Vivitek D537W did not have too much of a problem maintaining a consistent black level. Only when the black area is a very small percentage of the screen, about 5-15%, did the brightness of that black start to rise considerably.
Projectors do not display an even illumination across the screen, typically. As you can see in the chart below, the Vivitek D537W's luminance bounced around considerably, with the bright portions in the center, then trailing off towards the edges. This is about the same performance as we've seen with similarly priced projectors.
The greyscale gamma measures how well a projector transitions from white to black within the greyscale. The chart below tells us several things. First, we're looking at the smoothness of the line. There are virtually no bumps, so you can expect smooth gradients in the greyscale from the Vivitek D537W. Secondly, we're looking at the evenness across the intensity range. Some projectors lack detail in the shadows, others lack it in highlights. The Vivitek D537W was good enough to provide even luminance throughout the range. Finally, we're looking at the slope of the curve. An ideal slope is between 2.1 and 2.2. The Vivitek D537W's performance of 2.3 is very close, but a bit steep.
