This site is also the first sun light bulb player to play smart, micro-projection what play: BenQ BenQ i720 home projector
It is my expectation for many years to build a surround sound audio system with 5.1 or more projections to watch movies at home. He had been living in a company dormitory before, and he took the projection of the company back to see a movie. The sound could not be expected. Later, I had my own house, but I couldn't install it directly because of budget problems.
But before the renovation, I did my homework and researched various wireless products that realize surround sound. I thought about how to hide the installation projection of HDMI cable and how to solve the curtain. Although there is only one TV in the living room, I can add a full set of equipment at any time.
Even when I bought a sofa, I thought it was a matter of comfort for the Emperor. However, the plan to install projection and audio in this living room has been completely grounded, because there was an unexpected episode at the beginning of the month: We bought another house and we have entered the decoration period. The new house plans a dedicated entertainment room. Of course, the home theater is the main project, so the projection has officially entered the selection period.
Feel micro-cast:
In the intervening period of the home theater in the past, I engaged in a hot LED micro-projection in the past two years: using the Z4air to use it, and using it in conjunction with a Bluetooth speaker is perfectly feasible in the horizontal alternative television, although it has only 720p resolution. In the dark horizontal cast a seventy-eighth inch can have quite good results.
Z4air this micro-projection is very light and compact, can easily be loaded with a small package. When traveling abroad, we also took it with us. At night, we didn't want to go out and buy some beer. We watched the USB flash drive or ipad in the hotel. My daughter-in-law also liked it, saying that it was the most worthwhile electronic in these two years. product.
With it there are also several models of mango yo yo, cheek color, etc., is nothing more than the difference between the built-in ROM and remote control, the lowest can be achieved within 2,000 prices, should be the most cost-effective series of 720p micro investment, I also give Many friends Amway had this product.
But the 720p resolution is its flawed, this resolution in the horizontal 3 meters viewing distance, 80 inches is the basic limit, and then the assembly has a clear grainy, apparently for home theater whether it is brightness or resolution Not a big reality. But I do meet a lot of people on the Internet to hoist 720p micro-projections in the living room. I asked them why they do not need to be portable. They did not consider the light bulbs. They actually asked me if the light bulb was not eliminated by the LED. Micropropagation is terrifying. . .
When I was full of joy and waited for the launch of the 1080p micro-projection meter H1 and nut X1, the expectation basically became a bubble. Their volume, weight and price all caught up with the level of the bulb projection, but the brightness was far lower than that of the bulb machine. . To know that the 1400 ANSI luminosity LG PF1500 is only half the volume of H1, it is clear that this generation of domestic micro-projection did not work hard on "micro".
According to the official DLP chip manufacturer: Texas Instruments (Ti) official data, the 1080p chip size is 0.47 inches, which is only 0.2 inches larger than the 0.45-inch 720p chip used by Z4x and Aurora, and the area is only increased by 9%. Typical brightness value It is also the same as a 0.45-inch chip. Obviously, H1 and X1 have a lot of slimming space.
The protagonist appears:
For so long, in short, this time I chose to focus my projections on the light bulbs. But this i720 was not bought by me. It was a friend who asked me when I was H1. I was discouraged by the choice of light bulbs. I asked him to borrow. Try it out, so the out-of-box process is gone. As for myself, I haven’t decided yet. Anyway, the decoration will not end until the end of the year. I’d also like to see if there are more suitable models. (Actually, as long as there is a god price, it's all agreeable.)
Compared to my Z4air, the i720's volume is very scary, but it is used for hoisting. The volume is not a constraint. Then why did I dislike H1 too much? Because the light bulbs are basically 0.65-inch DMD chips, and the projection optical structure is basically the camera in turn, the difference between the emitted light and the collected light, the rules of the end of a large pressure dead people in the same set up on the projection. H1 micro-investment ah, micro-casting should be able to take away at any time, can not take away Why choose micro-investment? Just like a camera does the size, weight, and price of SLR, but it is the specification of the card machine. What reason does not buy SLR?
The remote control of the i720 is also extremely large compared to the Z4air. The remote control of the Z4air is the most common Android remote control. It is also very common on domestic smart TVs. There are only a few buttons, and the i720 is The keys are full.
The buttons of the remote control can be roughly divided into five functional areas, in which the area for image quality adjustment is rarely used after the setting is completed, and most of the projection setting parts will not be used. If BenQ can provide a simplified remote control, it will be more suitable for home use.
The remote control will have a red backlight, which is a very practical design for projections that work in dark environments most of the time.
I720 provides a very rich interface, all basic equipment can be easily connected, the middle is a WIFI antenna.
At the top is a simple set of buttons. The chances of using them are very low. Basically all remote controls are operating.
The large frontal lens is the obvious difference between the micro-projection and the light bulb. As with the camera, the larger the bottom, the larger the required lens and the better the optical performance that can be achieved.
Above the lens is a knob to adjust the lens parameters: focus, zoom, and up and down.
There is also a door outside the knob that can be covered to prevent dust. The design is very intimate.
The left and right sides of the fuselage are vent holes. The heat output of the light bulb is still larger than that of the micro-projection. There are 3 cooling fans inside the i720. Because of the larger fan, it's noise control is not bad, and no more noisy than Z4air. On the contrary, Z4air's fan is too small to cause excessive speed, higher noise frequency, and more harsh sounds.
The most people vomiting or the warranty label, since it can not be torn, so choose a color close to the shell, ah, this blue is too garish.
Since there are no curtains at home and the time is short, I simply tried some basic functions.
The BenQ i720's smart system is more like an Android box inside the projector, and its integration with projection is not very tight. For example, smart TVs and micro-projection products boot directly into the smart system. The smart system has taken over all the functions of the machine. All signal source switching is actually selected through the intelligent system. Although the i720 will boot into the smart system, its smart system is completely self-contained. All projection settings use the traditional projection menu. It seems to me that this is a great advantage. This is what I have experienced since switching to smart TV. I will explain in detail the part of the projection color setting.
smart system:
The i720's smart system home page is very simple and only lists built-in functions and installed apps. In the APP section, I will not introduce too much. Each projection or TV is similar. The magic here is the application market.
In addition to downloading the APP, this application market also provides live TV and various on-demand features.
Of course, access to various sections or provide a large number of APP downloads.
The mainstream movie and TV APP is quite complete.
The design of this intelligent system is simple enough to be abhorrent, with only three sub-sections of network settings, basic settings and system information.
Only the input method and language can be changed in the basic settings.
More settings are the standard Android interface, just remove some content, the interface has not been modified.
The system version is still old 4.4, but for a projection it is not a big deal, as long as you can find the film you want to see.
Projection settings:
Compared with simple intelligent system settings, the i720's projection settings are extremely professional, and can be set much more than micro-projection products.
For example, it can choose the color of the wall, I try the projection of the main bedroom wall, but the milk coffee color, as long as the selection of light yellow can greatly improve the color of the projection. Light bulb projection or projection screen is the main thing. Portable micro projection is where to find where to invest. It should also be added to the setting.
The i720 has many parameters that can be adjusted in terms of color. This is an essential feature of the component home theater. The i720 sets intelligent systems and projection functions in separate ways that also provide great convenience for color adjustment.
Since changing smart TVs, I have been troubled by adjusting the colors of televisions. Because the intelligent system completely took over all the parameter settings, in order to adjust the color we must first return to the desktop to enter the setup menu, adjust the return to the playback state to see the adjustment effect, you need to toss a long time to adjust a good competition. The i720's projection settings are completely independent, you can directly call out the adjustment menu during playback, real-time preview adjustment effect, saving too much!
Lamp life:
The i720 offers three modes of operation: normal, energy saving, and smart, and is normal by default.
As can be seen from the lamp timer, working hours in the normal mode for 63 hours, the equivalent bulb usage time is doubled. BenQ's projection uses an Osram light bulb, which advertises that it can operate for 6,000 hours in SmartEco mode. Even if it only takes 3,000 hours to calculate, it will be able to watch a movie every day for 5 years. Not to mention how high the cost of changing a light bulb, LED projection 5 years ago? Can you see the current LED projection after 5 years? It is really a little redundant to entanglement this issue.
Keystone correction:
The i720 provides a vertical lens shift function. The above figure shows the up and down adjustment limits of the screen that this function can achieve. This displacement is smaller than I expected.
I720 also provides a trapezoidal correction function up and down, the pole meter on the Z4 aurora increased about 1000 trapezoidal correction price increase, but I personally do not have any good feelings about this feature, there are two reasons.
The first is because the projection and the camera have the concept of focal plane and depth of field. Only the curtain is just on the focal plane of the projection, the image being cast is clear, and it will be blurred when leaving the focal plane. When the projector is facing the curtain, the curtain overlaps with the focal plane, and the entire image can be clearly defined. When the side plane is in focus, the focal plane and the curtain have an angle. The resolution of the entire screen is inconsistent, and perfectionism is difficult to accept.
The second reason is that trapezoidal correction can cause serious loss of image quality. The picture above shows the effect of the trapezoidal correction when the projector is facing the wall. You can see that the picture size has become smaller and the black pixels have been lost.
The above picture is to put the projection to the side and correct it with trapezoidal correction. The red part of the third frame is the lost pixel.
Let's take a look at how big the loss is. This is an app icon that does not open the keystone correction. It can be seen that the horizontal lines are composed of two pixels and are very clear.
After trapezoidal correction is enabled, some pixels are lost and point-to-point cannot be achieved, and sharpness is significantly reduced.
Therefore, if there is a requirement for the picture quality, it is necessary to find out the position when installing, or do not count on trapezoidal correction. Restricted installation conditions allow you to spend more money on machines with lens shifts.
The simple drying of the singles is just the end of this way. The i720, a light bulb with a built-in intelligent system, is also considered to be the inevitable product after the popularity of smart TVs. This will make 1080p LED projections have almost no advantages other than appearance. No effect was mentioned above because the effect could not be shown. The setting of the camera parameters can make the screen shots a world of difference. The screen shots of a single machine show the shooting level instead of the projection effect. The screen shots are only useful if they compare two machines under the same conditions.
There is no mention of the built-in 10W2 speaker, because the sound quality is really terrible. But I will not take it as a disadvantage, since all projections, set a good sound, do not expect the built-in speaker. Even if the built-in sound effects are no good, it is no good. After all, the projector is located near the viewers and even behind them. Looking at the front curtain, the sound from the back of the head can be heard. Such a movie viewing experience can be tolerated. Really. Is it necessary to project it? Projection emphasizes sound quality is the cart before the horse!
The i720 does not have a Bluetooth function and cannot connect a Bluetooth speaker to improve sound quality. If you want to replace it with a portable LED projection, it is obviously not appropriate. It is more suitable for wiring and ceiling installation, component home theater use, built-in intelligent systems can also fully play its role.
My biggest opinion on the i720 is still appearance. Although it looks a bit Q, it is very big and it is difficult to integrate into the home improvement.
So in the end I would like to solicit opinions on the entertainment room in the future: Because of the high brightness of the light bulb, the reflection of the white wall will cause the whole room to be bright during this use. Reflectance will even affect the color of the picture. It is necessary to put the wall and the floor. Are you getting dark?
