Two full-HD 3D DLP projectors in the test

Projectors in the test


3D technology


Not long ago, it seemed almost as if the DLP technology were extinct and replaced by liquid crystals. However, the technology with the mirrors of Texas Instruments strengthens the technology and plays out their super-fast switching cycles fully. The testers ordered the BenQ W7000 and the Mitsubishi HC7800 to test: two representatives of the middle class with a lensshift lens.


Image quality


In many respects the two candidates are similar: for example, in their size. But they differ significantly in the control of the 3D signals. BenQ uses DLP link and clocks his glasses with red impulses in the image across the screen. Mitsubishi works with an external infrared emitter, which comes as standard with the projector.


Conclusion


Mitsubishi uses innovative shutter glasses, whose liquid crystals are not conventionally switched by means of electrical voltage, but by magnetic fields. The advantage: This allows shorter switching times than with electrical stimulation. The disadvantage: The Mitsubishi glasses are relatively heavy on the nose and have quite small glasses, which just reached so in the test cinema from 4.5 meters away the 2.66 meters wide 16: 9 canvas to see

The eyeglasses costing 169 euros per piece, compensate for this with a color-neutral, contrast-rich image, which left quasi free from ghost pictures a pleasant, cinema-like 3D impression. The conventional shutter glasses of the BenQ for 99 euros offered an excellent picture with very few ghost pictures and a similarly fine contrast in color and contrast in the 3D image. It sits comparatively light on the nose because its electronics have been cleverly shifted backwards into the brackets.


If you are facing both projectors, the BenQ with its much brighter image. On the other hand, the Mitsubishi scores with noticeably greater contrast.


Calibrated, they differ little in the colors. But the W7000 looked more nervous in the test and showed more grumbling than the HC7800, whose image was much quieter and much more deeply mediated, which is probably due to its more complex signal processing.


This impression intensified when the testers tried different image enhancers. The adaptive aperture of the BenQ worked well, but worked visibly sluggish, apart from their working noise. The Japanese light modulation was present in almost every setting, and, fortunately, hardly audible.


The HC7800 was also less unnatural in the interim image calculation. This is also necessary, since this is always active in 3D mode. With the W7000, the interim image computation can be switched on in 3D mode. During the Blu-ray playback with 24 Hz in 3D, you do not need it, which overcomes the projector via the clean pull-down.


Since he works like all current DLPs in 3D with 120 hertz, they have to be switched on at the latest during the 3D playback from the TV - the testers chose 1080i side-by-side shots of the Olympic Games by the BBC, otherwise Jerky the images quite violently. In the middle of the parameter, the images looked quite good.


In contrast to many other projectors, both test devices showed 3D images with correct gamma and thus natural brightness shading. The eye also detects depth information on the gamma.


LED vs. 4K: High-end Beamer in the test


Because in both cases the depth information was correct for each eye and the image separation of the 3D shutter technology worked well, both projectors showed a wonderfully harmonious, 3D-representation of astounding plasticity. Since many an expensive current projector likes to cut a slice of.


BenQ and Mitsubishi delivered a good performance for the money in 2D and even in 3D mode. Whoever wants this is exactly the right thing for both projectors.


With BenQ and Mitsubishi, we have found two wonderful all-round talents. So far, almost always the 3D rendering of the 2D qualities with affordable projectors, these projectors show that both can be brought under one roof.


What the BenQ W7000 is lacking in contrast, he makes up for with Lichtpower and is therefore particularly suitable for living room and gaming. The Mitsubishi HC7800 shows a wonderfully balanced, quiet image already in 2D with a plastic depth - perfect for the home cinema.
