Optoma HD141X - DLP Projector - 3D - 3000 ANSI lumens - 1920 x 1080 - widescreen projector HD141X / Full HD 1920x1080 / 3000 AL / 23000: 1 / Full 3D / 1000 h / 2xHDMI (Office supplies & stationery).

Customer Review

I tested the unit two weeks extensively.
The differences between the HD26 and the HD141x are only in the casing color (HD26 know HD141x black).
The different data for brightness and contrast are pure marketing values ​​and in practice there is no difference.

In short, the projector is extremely well equipped for the price of around 500 (HD141x) and has in my opinion currently the best price / performance ratio for a full HD entry-level DLP.
The offered light output as well as the very good contrast and very extensive setting is the unique strengths of the unit.
Professional requirements for home theater (Tagged Image quality) are not entirely met from HD141x by RGBCYW color wheel.
Nevertheless, the device is well suited for use in home theater as well as in presentations.

Unfortunately, the Optoma HD141x (HD26) is affected by an enormous series dispersion in the field of optics. Here you have to be lucky and persistent a unit remain to be caught, which is ok.
The following properties of the image can be influenced by the series dispersion:
- The image edges (straight vs. odd)
- Discolorations in Black image (red or white)
- The distribution of brightness (dark or light spots or corners)
- The grinded (uneven focus)
- Fringing on contrast edges

In this above points you should pay attention and consider whether they are still in the frame.

Here is a quick comparison of the positive and negative characteristics of the Optoma HD141x.

End of the short review!

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

Here are the details for all who are looking for more information / impressions about the device:

The packaging is sleek, glossy without pressure, with side handles. The projector has sufficiently cushioned (air foil) kept in the outer package. The remote control is with blue lighting and looks rather cheap. But there is unfortunately no bag included.

The housing acts stable and relatively high quality. The individual housing components usually run together without burrs. The partially built glossy parts protect unfortunately not very well from fingerprints. The screen protectors are cut so that they do not need to be removed for testing. In addition, the housing leaves little push.
In summary, the HD141x a solid case with no noticeable weaknesses.

The projector itself has the connections on the side, which has some advantages and has 2 HDMI ports. Furthermore, an audio output, a 12V trigger and 1 USB port are a VESA 3D port available.
This projector has three adjustable feet (1 foot in front and 2 rear feet). This is excellent for hosting at the table or shelf. Through the lateral connections, the device can set up perfectly on a shelf. The lens is pretty stiff but wobbles when adjusted Stark in all sorts of directions. The feet can be beautiful Unscrew far.

The image quality is set for presentations useful but also for the home theater operation suitable. Readjustment for use in Hein cinema is in this unit is not absolutely necessary, but recommended.
For purists, a usable CMS is present.

The white brightness is very high for a unit with 190W lamp (measured 2700 lumens). For the home theater, the color brightness is sufficient for average screen sizes. The color brightness is my tested device at approximately 1000 lumens. For presentations that plays only a subordinate role in HC but even more so.

It is not possible to provide the whole picture perfectly sharp.
This problem has in this form but all projectors in this price range and is due to the relatively inexpensive optics. After a short adjustment work but I did it manage to the discrepancies, apart from 2 corners, at max. To adjust 1/2 pixel. I assume that everyone Optoma HD141x will have this problem varies depending on the series dispersion. 1 pixel offset to the worst point, however, is perfectly normal and had almost all of my devices tested.

Scattered light is forward scarce. Furthermore, the image edges are sufficient but not perfectly straight (max. 1cm deviation to 2 meters).
Chromatic aberration (color fringing, ghosting, 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 so solid and the price range to designate accordingly sufficient. Other manufacturers offer some increased and higher quality lenses here.

The distance from the screen should be at 296cm and 324cm HD141x between, is therefore relatively inflexible. This refers to the most commonly used screen width of 200cm. The projection rate is between 1:48: 1 - 1.62: 1, depending on the zoom. It is also important that the focus in the operation changed only minimally!
If you set them in cold projector, the image projector in the 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 from the manufacturer!). Otherwise, however, would have the more expensive lenses not have permission. But I must also say that there are quite are also optics in this price range that are almost perfectly. You have to get lucky!

The brightness is Optoma with 3000 (3200 HD26) ANSI lumens, contrast dynamically with 23000: 1 (25000: 1 HD26). I have a real on / off contrast ratio of about 3200 with my device: 1 measured, that is an excellent value. In the real brightness is the factory specification of 3000 lumens, and almost reached 2700 measured lumens on average. Subtracting like many other manufacturers the brightest part of the canvas for the brightness indication zoom (which is in my device perfectly centered the center of the screen is), so the HD141x even comes to around 3500 lumens.
Both the brightness and contrast were determined using a calibrated light meter.
By series dispersion of contrast and brightness by up to 20% may be worse. My device is more likely the best device with regard to the series dispersion represented in this respect. The illumination is on my device with 85% very good, the maximum brightness loss in the corners with a maximum of 60%, but very high. This is about 90% at a minimum decentered bulb and not directly at the light engine itself. In practice, these dark corners are not flashy.
Here are just the DC3 chip afflicted by a high series dispersion. Often scratches / residual cleaning solution on the protective glass of DMD exist. This can reduce the brightness and the contrast.

The dynamic black mode happens with this device via the change in the lamp voltage. The lamp becomes brighter or darker. Optoma controls here the lamp much more aggressive than other manufacturers. The working area of ​​the lamp is extremely variable.
The HD141x achieved in dynamic mode a contrast ratio of 6500:. 1 This value plays in practice no role, since this can never be achieved natively. A value of 3200: 1, however, is pretty much the maximum achievable even awarded for a DC3 and in the price range of HD141x.
-------------------------------------------------- --------------------------------
I try to explain why the dynamic contrast can not be achieved in real terms (eg Acer P1510):
The projector reaches a maximum brightness of 1900 lux at a pure white image (a bright lamp mode). With the same lamp brightness of the projector reached in the same place at full black around 0.65 Lux, what a contrast ratio of 3,000: 1. In dark lamp mode the projector reached with full black a value of about 0.48 Lux. At the same time, the maximum brightness of 1900 lux to 1500 lux at the same point decreases. The contrast remains at about 3000:. 1 However, the manufacturer shall use the lightest value in high lamp mode and the lowest value in low lamp mode to determine the dynamic contrast. This would, however, even in theory only 4000: 1.
As the bright light mode and the dark mode lamp but never at the same time may be present, the dynamic value is completely irrelevant. The only value that is enhanced by the adaptive light control, the black level. This is the P1510 with 0.65 lux for the offered brightness absolutely fine.
-------------------------------------------------- ---------------------------------
In light angedunkelten space the image is already very good, and even nearly perfect in all dark conditions. The Eco mode is definitely sufficient at 2m picture width in the home theater. The colors radiate and are fed up. Again, something that speaks for a sufficient brightness of the device. The black level is very good, given the very high light output. Other DLP's with Dark Chip 3 reach unaided (mechanical diaphragm) also hardly values ​​below 0.4 lux at a comparable image size.

The brightness values ​​(in lux) for contrast and black level were determined on a canvas with 2,85m².
Since the conversion of Lux is quite complicated in lumens, I'm here not respond.

The volume of the Optoma HD141x is significantly quieter than the Acer H6520BD and in my opinion, absolutely 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, except in the home theater with a corresponding sound system.
The normal lamp mode is when HD141x loud that same is true for dynamic mode.
Therefore, the first choice when HD141x the Eco mode.

The internal 10W speaker is sufficient for emergencies but only slightly better than the Speaker of the Acer H6520BD.

The projector has built three internal fans, but they are so thoughtfully placed to ventilate the whole projector and the Elektonik well. The fan generates only one air noise, no hum or high frequency hum. The fans run in Eco mode to about 2500U / m, but that depends on the ambient temperature. There are menu unfortunately only 2 of the 3 fan monitored. Probably the 3rd fan is not critical in case of failure of the projector and is therefore not mitüberwacht.
The outlet temperature is mediocre (around 60 degrees), but you should plan the placement of both.

The settings are sufficient for the home theater operation. There is a complete CMS and the Brilliant Color feature can be switched off. Who gets along with the default settings, the unit can also be used without modification in the home theater. For presentations, the device also has more than enough settings. After all, the HD141x with Brilliant Color feature is enabled only a small yellow-blue surplus. Therefore, one can use the function without problems.
The white segment and the other two segments of the secondary colors are significantly smaller than the 3 primary colors. This should not so much drift into the cold as with other devices, which usually have much larger segments of white, cyan and yellow color.

The 3D capability with normal DLP glasses is excellent. Both the effect of depth, brightness, and the pop-outs are well. Flicker and ghosting are rare. For 3D Cloudy with screen up to 100 inches this projector is sufficient color brightness could also be higher. Through the good contrast, the screen looks sufficiently plastic.
When HD141x 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, the device supports not officially, but it can also be activated without a 3D source, 3D mode. The image is then displayed in 3D. Another highlight of the HD141x is the ability to output a 3D signal as 2D signal.
One can select the left or right channel. Thus, can be combined with 2 HD141x a restricted passive 3D Stack realize.

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 HD141x is what concerns the rainbow effect, good. I see the effect sometimes despite the good brightness and only 2 to 3-fold color wheel speed.
The speed of the color wheel is native, this machine max. 3 times (depending on the input signal) and in 3D mode 6-fold.
But I also see the Benq W1070 + with its 6-color wheel and the much lower lumens the rainbow effect on a regular basis, though not as often as the Optoma.
But I could live with both devices using the RBE.

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 HD141x both effects are virtually non-existent.

The projector uses a 190W UHP lamp Osram (P-VIP 190 E20.8) and consumes about 225W on average. This is appropriate since only around 25W are purely used for the electronics. A replacement bulb costs about 150 or (60 as a bare lamp), which is moderate. The life in eco mode is above average with up to 8000 hours. The Beamer is a very economical device in terms of power consumption.

The difference from 720p to 1080p can be seen for me already, even if the individual pixels can not really identify with 2m picture width even at 720p. The main advantage is the much weaker form of the optical errors by the optical system for me. This point is more important for me than the higher resolution itself. The 200 more there are compared to an HD-ready device but my worth, even if it is the biggest difference is not in movies, but probably at presentations notice.

Optoma's 2-year warranty without onsite service. The support is said to be fine, but I have this still do not have their own experiences.

In summary, one can say that the Optoma HD141x (HD26) in its price region the better Acer H6520BD is currently, as long as you do not need the high brightness of the Acer.
The Optoma HD141x is suitable for use in home theater as well as for presentations alike.
The not quite perfect appearance corresponds to the price and will be better in the competition only with luck. The appearance is now time cheap goods, otherwise the price would not be feasible. The optics roulette you with any manufacturers! Optoma has unfortunately always been a high dispersion with respect to the optics (keyword selection).

I hope this review helps others something in their purchasing decision.
From my unit gets 5 price / performance star for use as a presentation projector, and also 5 star for use in home theater.

However, there are so some other things that would have Optoma can do better:

- Better image edges (hangs easily, 1.0cm)
- An Extreme Eco Mode as the MW523 for less lumens
- A higher quality lens
