Build a cinema at home — ViewSonic ViewSonic PJD7720HD Full HD Projector Experience

Foreword:

The author moved his new home at the end of August. According to the wonderful room structure, the author's bedroom has only one wall. The bed is against the wall and the bed is facing the wardrobe. Left window sill, right bathroom. In theory, television should be facing the bed so that you can watch TV. Again, it's bad to have a 45-degree angle on the side, but room space is not big enough. As a result, there is no suitable place for TV. Well, although the space for 43-inch TVs is set aside in the closet, it has long been occupied by the author's clothes. The window sill can be placed, but in that direction, the sun is shining in the morning. If it opens on the rainy day, the rainwater will pour in. Based on this special space, the author can only consider it separately. Because the author is an IT engineer, the unit is a computer company, so the author is still more convenient in some aspects, plus I like to watch movies, have a preference for the big screen, so I directly took a projector from the company, the price is natural purchase The price, er, the things of your own company, try not to use it, you can get it back, and it's more convenient. The author bought a ViewSonic PJD7720HD Full HD projector from the company and took the company's back curtain to test it.

product details:

ViewSonic PJD7720HD outer box is relatively small, I installed a lot of projectors, generally larger than this box. The corrugated box material was used, but the texture of the box was soft, which made the author feel a bit dangerous. After all, the projector's value is not low, because if the box causes the machine to have any problems in the transportation process, it is not good. This point hopes that the latter manufacturers can strengthen. On the right side of the package is a three-husband of the ViewSonic Logog. On the right side are some features of the model and ViewSonic PJD7720HD. The ViewSonic PJD7720HD is a DLP projector. The side of the side is to introduce the manufacturer's related information, the other side is to introduce the packing list of ViewSonic PJD7720HD, three-dimensional and volume weight and other parameters.

ViewSonic PJD7720HD body with all black plastic material, the surface metal brushed touch. At first glance, it may be thought that it is a metal shell. The overall design is relatively rounded. Measurements are: 316 * 228 * 104mm, net weight is 2.4KG, this weight is really light, compared to other projectors I installed in the past.

The upper left corner of the ViewSonic PJD7720HD is a focus circle and zoom circle, which is very useful when positioning adjustment, it is an absolutely necessary function. Fortunately, the zoom circle is mainly to control the size of the screen projected on the projection screen, and the focus circle is whatever the projector has, otherwise it is useless.

The buttons of the ViewSonic PJD7720HD are centered in the middle of the fuselage. However, this button design I do not like, some icons, some English, can give some Chinese, and then clearly marked some. Even if it is in the side of a specially designed lattice to label it okay. Although the author can see the icon is also able to see, but believe that here can make many people directly look dumbfounded.

The top features of the ViewSonic PJD7720HD are marked with the main features.

The back interface of the ViewSonic PJD7720HD is a place where the author was surprised. I previously installed to the customer are business / teaching projectors, there are many engineering machines, which is not full behind the interface, and can not wait to do full body. The ViewSonic PJD7720HD is a very save, only designed audio interface, HDMI interface, Mini USB interface and RS232 window position. Not equipped with a standard USB interface, it seems that mobile storage does not support direct read playback. Because I was considering connecting to a cable set-top box and a network box. Fortunately, the new set-top box is also equipped with an HDMI interface, or I don't know if I can support the transfer interface.

ViewSonic PJD7720HD on both sides and the front, are reserved a lot of cooling holes, the projector's heat is called horror, so need a lot of cooling holes and fans to quickly discharge the heat generated by the bulb, to ensure the temperature inside the fuselage Not too high. On the right side, there is also a rip-proof label. Normally this kind of thing is not to be demolished.

The right side of the ViewSonic PJD7720HD is on the right side of the lens, but I was surprised that the fuselage did not match the lens cover, this feeling should not be. Hope that the latter manufacturers can improve.

Because the design of the ViewSonic PJD7720HD has a zoom ring, this lens is scalable, so that you can better control the screen zoom.

The back of the ViewSonic PJD7720HD is mainly a fixed screw point and three feet of the hanger, wherein the upper feet can adjust the length to raise the tilt angle of the projector. When the projector is placed on the desktop, it is used to raise the position and adjust the screen. This is more practical. As for the screw position of the pylon, I have always been repulsed by this irregular design. Of course, this is a matter of consideration. However, if we want to adjust the stent to a suitable position, it is very costly for brain cells.

When the ViewSonic PJD7720HD's fulcrum is adjusted to the longest point, there are about 15 degrees or so, and there is no tool to measure it.

In addition to the large number of cooling holes on the left side of the ViewSonic PJD7720HD, there is a filter, this side is mainly the air inlet, so use the filter to filter dust foreign objects, keep the internal space clean. Filters are mounted by snaps and can be easily removed. The filter covers this screw at the same time. This screw is used to fix the position of another interface. I took it down to view it. Is the second HDMI interface, looks like it is used to insert wireless modules.

ViewSonic PJD7720HD comes with some accessories, including a CD, a warranty card, a quick guide in English, a remote control, AAA battery 2, a power line, so I was surprised is not even equipped with HDMI cable , The whole machine is such a display interface, actually does not wiring, is not a smart projector, comes with the system can not need an external input source. This really made me very puzzled. Fortunately, I bought an HDMI cable before I bought TV, otherwise I can't really play it.

ViewSonic PJD7720HD comes with a CD-ROM, but then I read it, in addition to a large type of manual and a remote management software for the projector is a bit of value, the other is useless. In this respect, the author's bad review is not as good as a special detailed specification. Especially the CD packaging design is still in English, this design has always been very disliked by the author. Pure Chinese is not the best. At the very least, Chinese and English are also required. English does not understand much, such as the author.

The power cord is a very common specification. It is like a computer power supply and it is easy to find alternatives.

The volume of the remote control is relatively small, but the functions are relatively complete, and the layout is better. But the same problem, the icon + English, the space between the keys used to add text more than enough. The back is mainly the battery compartment, the front end is an infrared emitter, infrared good, I believe you can use the phone to control, as long as find the right APP and infrared code library.

The two Maxell's AAA batteries were delivered to the remote controller.

Experience:

The screen is a 16:10 100-inch bracket screen, white plastic material, the advantage is cheap, first to test the next effect, if you can buy yourself. Fortunately, the author has measured the size of the home's space and the company's curtains. It is almost as good as it is. Of course, if you come out again, the space will be bigger. The back of the projection screen is not the window sill, the right side is the wardrobe, the left is the nightstand, put the projection screen here, the location is still relatively good, originally wanted to say placed in front of the wardrobe, this direction is more positive, but the distance is not enough. And it doesn't seem to be enough for the bracket to be placed. If you later buy it, you may want to consider pulling the curtain so that it can be placed in front of the wardrobe. Of course, the choice of curtains is also more, white plastic, glass beads, glass fiber. Electric screen, stand screen, floor pull screen, etc. The author's home is only suitable for brackets and screens because they need to move. The material can be picked again. Anyway, if it's used for personal use, it will be fun when it looks better.

At the beginning, it took the ViewSonic PJD7720HD, mainly fancy 3200 lumens, 22000:1 contrast ratio, as well as full HD resolution, and support for 3D, you can also choose to match the wireless projection module, the price is relatively cost-effective, so take this Taiwan to try. By the way, the following pictures taken by the author only adjust the resolution size without any modification.

Since the ViewSonic PJD7720HD is not a smart projector, there is no built-in system, so only language options are available at startup. The system presets a variety of languages ​​for users to choose from. The author naturally chose Simplified Chinese.

ViewSonic PJD7720HD's function menu is still relatively rich, but the function of trapezoidal correction is relatively weak, only provides a vertical trapezoidal correction. In this regard, the author believes that the function of the trapezoidal correction is the strongest, and it is most convenient for the calibration of projection screens. Due to the lack of a well-placed platform, the author needed to find something to raise the projector, and also encountered the ViewSonic PJD7720HD with vertical body correction function, so the author used a lot of time in correcting the projection screen before adjusting the relative comparison. Almost some.

The author is using a computer linked ViewSonic PJD7720HD. Fortunately, the author's video card also has a HDMI, not the full DP interface, or really a headache. Although the brightness of 3200 lumens is not very high, it is still quite good. In the daytime, the display effect is still possible.

This time the author tested the ViewSonic PJD7720HD, using a variety of pictures that were often used to test monitor TV. The projected picture of ViewSonic PJD7720HD looks brighter than the monitor. However, the details and colors performed fairly well. Color reproduction is also more natural and true. The details of the performance are better, especially the back of a few bright colors of the picture, the performance of the author satisfied. I used two smart projectors before, but also used these images as a test, the effect is far less than the ViewSonic PJD7720HD.

Select the projector, the author naturally wants to watch movies, all kinds of big movies. You know, the author has collected a lot of Blu-ray original discs, more waste on the computer to watch, and now there are projectors to test, it is natural to come and experience to see. The result is also to make the author more satisfied. Because the physical resolution of the ViewSonic PJD7720HD is 1080P, so whether it is from the pictures, or the movie, in the projection of the author to the 100-inch screen is, both the screen display is still relatively fine. This is the advantage of high resolution. If it is still the resolution of 1024*768 or 1280*800, there will be some rough graininess at this time.

With ViewSonic PJD7720HD to play the game, this is the idea that the author suddenly emerged after connecting the projector with a computer. I like the big screen, the display directly on the 27-inch, so the picture will be better. If you think about it, if you use 100 inches to play the game, then the estimate will be more shocking. The author tested several games and had to say that the effect made the author very excited, but because of the larger screen, the author has to keep his head up. More tired. This needs to be adjusted later.

ViewSonic PJD7720HD is to support 3D, and the author's collection of resources also have a lot of 3D Blu-ray original disk, but unfortunately this time did not prepare 3D glasses, so no way to accurately test the 3D function, there are some small regrets, and it is worth mentioning that the built-in speaker. The author is a music enthusiast and has some research on speakers, headphones, and players. The requirements are relatively high. I believe that the built-in speaker effect is more general, in the absence of conditions external speaker headphones, you can click on it. However, I would like to experience a large film, I think we need to prepare the speakers, so as to have a real shocking audio-visual enjoyment.

to sum up:

Because of the work relationship, I often install and debug the projectors of Epson, Sony, NEC, Panasonic and other brands. The author is also familiar with those projectors, and also knows that those brands do not have cost-effective, these brands with the ViewShot PJD7720HD projector with the same price , The resolution is very low, the contrast is basically not as good as ViewSonic PJD7720HD, brightness is about the same. Due to the low resolution, the picture is not really effective after being projected to 100 inches. This point is a profound understanding of the author. So this time will try to ViewSonic PJD7720HD, from the overall performance, let the author still quite satisfied, in the various tests of the experience inside, all aspects of performance are good. However, the weak trapezoidal correction function is a weakness, and less interface is more troublesome. Because the author's original goal, to pick up the set-top box and network box, at least 2 HDMI interface, and the author may now be connected to the computer, so that the interface is insufficient. So I also need to add a third of the HDMI switch later to try. I believe the problem is not great. Next, the author will need to take a double 11 to purchase a 16:9 100-inch projection screen. At that time, you can call friends and friends to come and watch movies at home. It's fun to think about it.
