calibrated significantly brighter than its predecessor (measured 2000 lumens vs. 1600 lumens). Otherwise the changes are manageable

I have the projectors now also home for several weeks even. He replaced my Optoma HD50, which is indeed advertised as the best single-chip DLP to 1500 ...
I have waited a long time and considered whether the W1070 + for my home theater is better suited than the HD50. The partly existing dust problem with the company equipment (4x W1070 +) has made my decision even harder. Since the Optoma HD50 only a contrast of about 1000: 1 and reached the image thus achieved only a small depth, I have it but then ventured.
And I can only say that the "downgrade" provides a much more plastic image.
The FI of the HD50 I miss though sometimes that it ended up being even.
The image of Benq W1070 + is much more plastic and more contrast than the HD50. And lighter by 10% is the W1070 + also (same environment, both uncalibrated beamer to Settings "DMD Full On"). And after 100 hours, no dust on the chip. In my experience, is the dust either after only a few hours a DMD chip, or if not, then even after prolonged operation usually not.

Here the innovations of the W1070 + in detail:
- The brightness has been increased to 2,200 ANSI lumens
- The Benq W1070 + is in Eco Mode with 28db on paper a little quieter
- The menu has been completely revised (easier for laymen)
- Horizontal Keystone corrector

In short, the projector is for the price of around 780 good for presentations and for home theater perfectly suited. Best wait for a lightning deal because the W1070 + is then often get for under 700.

Semi-professional requirements (Tagged image quality and setting options) are as already the W1070 without +, even partially fulfilled.

Here is a quick comparison of the positive and negative characteristics of Benq W1070 +.

Please note that I can only speak for my Beamer here. By series variance in this price range, it may be that you get delivered a better or worse copy!

End of the short review!

-------------------------------------------------- -------------------------------------

Here are the details for those who seek more information / impressions about the device:

The packaging is glossy-foiled, with carrying handle. The projector has sufficiently padded foam form kept in the outer package. The remote control is with reddish lighting and looks very high. There is no case included, but is not really needed in a home theater projector.
The Free bags are mostly anyway quite cheap and have little padding, so you should buy more high-quality bag for a transport envisaged.

The case of the W1070 + acts stable and relatively high quality. The individual housing components usually run together without burrs. The partially built glossy parts protect but unfortunately not very good against fingerprints. The screen protectors are cut so that they do not need to be removed for testing. In addition, the housing can be pressed only slightly.
In summary, the Benq W1070 + a solid case with no noticeable weaknesses, as the predecessor. The protectors should be removed after testing, because the films can be removed only after a long period still difficult and not entirely under certain circumstances. During operation, the housing cracks sometimes by the high temperature inside the appliance and the lamp.

The projector even has the rear ports, which will be convenient for most people and 2 HDMI ports. Furthermore, a component input, 1 VGA input, a VGA output, an audio input, an audio output and 1 USB port and a 12V trigger are available. Unfortunately, the USB port is in off Beamer not function and does not load equipment. That's too bad, because the port would be perfectly suited to eg load a DLP glasses.
The W1070 + has two adjustable feet (1 foot in front and 1 rear left foot). This is useful for orientation at the table or shelf. Unfortunately, the thread is behind not very thick. You should back foot so not overly often use because the thread of time guaranteed rounds and then possibly no longer holds true.
The instrument optically does not differ from its predecessor, the lamp is also a 240W UHP lamp from Osram. If something has been changed to the sometimes dust-prone light channel, only time will tell. I'll keep an eye on it anyway.
The lens is pretty stiff and does not wobble. Also, the picture changes when focusing or zooming only slightly. But unfortunately "come from" the lens sometimes in place firmly. One must then apply some pressure and the focus ring in the opposite direction turn again to resolve this. Thus, the focus may be on puzzle.

The image quality is set for presentations and also for the home theater to very good use. Readjustment for use in Hein cinema is not necessary with this unit. I did not have to change anything on the need image. The pre-settings are already excellent. For purists, but ISF menu is available for all cases.
The brightness is also sufficient for presentations. For the home theater, the color brightness is very high and slightly higher than for devices with a white segment in the color wheel, but with much less RBE.
The color brightness is my tested device calibrated at 1600 lumens. For presentations that plays only a subordinate role in HC but even more so.

The sharpness is good to excellent depending on the device (serial dispersion) over the entire image. The same goes for the chromatic aberration (color fringing on high contrast edges).
After a short adjustment work I have but it + hammer out almost all tested W1070, the deviations on max. 1 pixel adjust. Each Benq has this problem to varying degrees, depending on the series dispersion. 1 pixel width CA / blur at the worst point, however, is perfectly normal and under. Devices with 1/4 or 1/2 pixel CA are to be regarded as very good. The focus should be as widely available in the best case, that, the individual mirror recognize (pixels) clearly delineated. This is from experience but hardly the case. In some corners is often a waste of focus to be recognized.

Scattered light is forward a little present but acceptable. Furthermore, the image edges are sufficient but not perfectly straight (max. 1cm deviation to 2 meters).
Chromatic aberration (color fringing, blurring, max. 1 mirror offset to the worst point) is minimal, as already mentioned above exist, but as part and no longer falls on from a distance.
On the whole, the appearance is therefore very solid and denote the price range in accordance with most devices as above average. Something better you get near the price not, unless you have extremely lucky a "good" model with respect to catch scattering.

The distance from the screen should be at W0107 + between 230cm and 300cm, so is actually relatively by 1.3-fold zoom, quite flexible. This refers to the most commonly used screen width of 200cm. The projection rate is between 1.15: 1 - 1:50: 1, depending on the zoom. It is also important that the sharpness in operation only very slightly altered. But this is so minimal that it does not have to readjust when warm.
If you set them in cold projector, the image in the projector warm state is not blurred.
Many others I tested Beamer had to be readjusted in the warm condition!

To adjust the focus there is a test image in the projector menu. Here you can adjust the sharpness well to achieve good sharpness across the entire image. 100% clean but you do not get out the image. The typical DLP color fringes in different forms and colors you always, depending on the series dispersion and quality of the optics. Up to about 1 pixel width you have to accept (is no reason for complaint at BenQ). Otherwise, however, would have the more expensive lenses not have permission. But I must also say that there are quite assembled optics in W1070 +, which are almost perfectly. You have to get lucky!

A unique feature is the adjustable offset the W1070 +. To speak of a real lens shift, here is actually not correct for the whole lens is moved with a lift.
Here you have the possibility to adjust the offset between 110% and 130%. The real adjustment is around 20%. By the manufacturing tolerances of the specified value of Benq may vary by 5%. Therefore, the minimum area may start already at 105% or until 115%. The maximum range accordingly between 125% and 135%. A guaranteed area has thus only between 115% and 125%, ie 10%.

The brightness is Benq with only 2200 ANSI lumens on the contrast with "only" 10000:. 1 I have a real (Smart Eco and BC a) contrast of about 3500 with my device: 1 and an average brightness of 2000 lumens measured calibrated that are both peak values ​​for a single-chip DLP with a 240W lamp. Where exactly the 200 lumens more come in contrast to its predecessor from the same lamp, is indeed questionable, but the calibrated brightness was actually increased by almost 500 lumens. Thus, the 200 lumens factory specification are even understated, if one uses the calibrated value as a reference. The dynamic Black mode is implemented in this device via the change in the lamp voltage. The lamp becomes brighter or darker. This is but only in a particular context (mainly between Eco and Normal mode) and not 100% in real time. This feature master all Optoma projectors far better.

In light angedunkelten space the image is very good and even absolutely perfect in very dark conditions. The Eco mode is sufficient 2,2m image width. The colors radiate and are very tired. Again, something that speaks for the good brightness of the device. The color brightness is only slightly less than the white brightness. The Brilliant Color feature of W1070 + increases brightness white, as opposed to devices with white segment in the color wheel, only around 500 lumens.

A really good black level reaches the W1070 + not. The black level of the W1070 + is still good for a single-chip DLP. Only the Acer H7532BD has a noticeably better black level in this price range, but all the disadvantages of a mechanical shutter.

The volume of Benq W1070 + is significantly quieter than the Acer H7532BD and in my opinion, acceptable in eco mode. The decibel information (db) provide little information about the actual volume level in the dynamic mode, which is probably the most used. On 100% Lamp power all tested devices are simply useless, unless you have a party. Since I no longer have the "normal" W1070 to compare, I can not say whether the new device has become really quiet. But what is for sure: the rapid speed change in the Smart Eco mode of the predecessor were anscheinen blunted massively, making them much more comfortable.

The internal 10W speaker is actually not so bad. He even has some volume and sound balanced pleasant. For presentations or even for normal TV mode, it is sufficient.

The Benq has installed four internal fans, but they are so well thought placed to ventilate the whole projector and the Elektonik well. The fan generates only one air noise, no hum or high frequency hum (if the fans are ok). The fans run in Eco mode between 2000-4500U / m, but that depends on the ambient temperature and the respective fan.
The outlet temperature is mediocre (approximately 75Grad), but you should plan the placement of both.

The menu has been completely revised and at first missing some settings.
But if you go into expert mode you will find all the settings of its predecessor as well as some innovation.
The setting options are a dream and you require for your home theater for a device in this price range. The possibilities are to be regarded as semi-professional.
I have performed a calibration on my test, the brightness while actually increased by 200 lumens.
Calibrated brings my W1070 + up to 1,700 lumens color and 2200 lumens white on the canvas.

The 3D capability with DLP glasses is excellent. Both the effect of depth, brightness, and the pop-outs are well. Flicker and ghosting are rare. For 3D-lovers of this projector is a good choice, because the color brightness is very high. Devices with white segment in the color wheel to bring little more color lumens onto the screen.

When W1070 + the lamp brightness on Eco can be adjusted in 3D mode with some other equipment that does not work, unfortunately. The triple flash 144Hz with only runs with native imagery, which is played at 24 fps. So either Blue-Ray with 1080 24p or via PC with the same settings. The projector then converts the pictures on 2x72Hz, ie 72fps per eye. This is absolutely flicker-free. In Sky 3D goes however not as Sky transmits in 1080i 50Hz. The glasses shutters then only in 100Hz and then you see the flickering light. 50Hz per eye are not flicker. 2D to 3D conversion support the unit, but this ability in my opinion anyway is no real added value.

The rainbow effect is very different in my opinion. I've been easily susceptible and see the effect very quickly, even though it bothers me only conditionally.
The Benq W1070 + is what the rainbow effect concerns very well, I see the effect only occasionally and much less than in devices with white segment in the color wheel. Compared with the Optoma HD50 RBE is comparable.
The speed of the color wheel is at W1070 + natively 3 times and a maximum of 6 times by the RGBRGB arrangement on the color wheel.
Many other devices without RGBRGB color wheel, it is easy for me to provoke a rainbow effect (rapid eye movements). Therefore, it definitely makes a difference what color wheel is installed and how fast it rotates.

One more thing on the subject of motion blur or ghosting:
Some devices fast movements result in contour shadow or be image content for brevity time blurred.
When W1070 +, this effect is scarce.

The W1070 + uses a 240W UHP lamp Osram (P-VIP 240 / 0.8 E20.9n) and consumes about 300W on average. This is very much because almost 60W are purely used for the electronics. This is consuming far more than many other devices (10W-30W). Presumably, the high power consumption is caused due to the rapid color wheel and the associated electronics.
A replacement bulb costs about 150, which is moderate. The life in eco mode is above average with up to 6500 hours.

Benq is unfortunately only 2 years warranty without onsite service. The support is said to be sometimes tedious, but I have to do this no own private experiences.

In summary, one can say that the Benq W1070 + in this price region currently is indeed slightly more expensive than other devices, but also partly can offer much more. For presentations and good for home theater, apart from the lack of inter-frame calculation, fully perfect.
The not quite perfect appearance corresponds to significantly more than you for the price of the W1070 can expect +. A "look-Roulette" you have at each manufacturer. Benq has but mostly a better selection of lenses. For me, the unit currently offers the best overall package for operation in the home theater, apart from the price. The color brightness is enormous and the device lightweight and portable. For presentations, I can also recommend the device (especially for video conferencing).

I'm missing only the nonexistent interframe calculation. But that's a matter of taste. With FI the device would be absolutely perfect.

I hope this review helps others something in their purchasing decision.
From me the device 4 receives price / performance star for use as a presentation projector, and 5 stars for use in home theater. From the image quality, in view of the low price for the performance offered the unit as a whole is at 5 stars because it is indeed to be a home theater projector.

However, there are a few things that would have Benq can do better:

- Better warranty conditions
- Better image edges (hangs easily, 1.0cm)
- An Extreme Eco Mode as the MW523 for less lumens
- USB charging even with switched-off device
- Somewhat smoother focus ring
- An inter-frame calculation (even if you can not wait for the prize)
