Smart TV has appeared a bottleneck period. Smart TV has changed people's lives, and has also gradually raised people's life positioning. More and more families can no longer meet the needs of smart TV. Many users who know how to enjoy life are starting to set up "home cinemas" and move the cinemas home. Gradually, 50 inch and 60 inch TV sets are not enough to serve as the windows of home theaters. At least the size of 100 inches+is satisfactory. The need for high-definition image quality, but also large enough, this time the projector began to enter people's daily life. A wave of projector purchase has begun. Although commercial projectors have entered family life before, if you want to choose a product that is suitable for you and not too expensive from a variety of products, you obviously need to learn more about it through the evaluation of some different products. Today, the author brings the experience evaluation of ViewSonic PJD6550LW projector;
Many netizens may still have their eyes on ViewSonic. ViewSonic was founded in 1987 and started with display products. After laying a solid foundation in the U.S. market, ViewSonic has expanded its market to the world. At present, it has many branches around the world and its products are sold in hundreds of countries. In fact, projectors and monitors are inherently visual display devices. On the basis of the accumulation of industry knowledge of monitors, they can be extended to the projector product line, which can highlight their advantages of showing everyone. The author also wants to say that ViewSonic has made mobile phones, which is unknown to more users. The topic is a bit far away. Back to the topic, let's talk about the packaging first. The logo of Three Birds is particularly impressive. It is Youpai's trademark logo. The inner packaging of the product is tight, so there is basically no need to worry about the damage of the product during transportation.
In terms of accessories, the author needs to explain that this product is a friend's, which is a second-hand product. The evaluation is purely a personal hobby, so it should be noted that several accessories are officially available, but the friend has not found them. In addition, a few small parts are not particularly important, and will not have a great impact on the evaluation, so it is omitted. Therefore, the manual, 3D glasses and removable dust screen are not shown in the photo. In addition to the three parts that can't be found, the overall Youpai PJD6550LW is quite rich in accessories. The remote control with infrared and wireless module have brought a good experience to this product of Youpai PJD6550LW. Of course, wireless modules and 3D glasses are accessories that need to be purchased in the package.
At first glance, Youpai PJD6550LW is similar to most commercial projectors in appearance. The big eyes are on the right, and a basically open cooling area is on the left. The color design is white on the top and gray on the bottom; It is understood that this product has only one color matching. There is no room for selection, but fortunately, the color matching is already excellent, and I believe there will not be many picky users. A closer look reveals that its shape is smoother.
Youpai PJD6550LW's upper cover plate also took some care. In order to have a more three-dimensional sense, the panel has been specially brushed. There is also a key area on the panel, which is mainly used to adjust some parameters of the projector, including trapezoidal correction, information source selection, key switch, etc. The lens part of Youpai PJD6550LW supports 1.3x zoom, and the effective projection range is 1-10M, and the projection size is 30-300 inches. The actual effect will be experienced later.
The appearance size of Yopai PJD6550LW is 316 × 103.7 × 228mm, and the weight of 2.4KG is relatively light. The interface is quite rich, 2 × RGB (input): Db-15， Compatible with color difference signal; 1 × remote control receiving port (front panel); 1 × HDMI 1.4 input; 1×HDMI/MHL： MHL 2.0 ； 1 × S-Video input; 1 × composite video (input): RCA interface; 2 × Audio (input): mini stereo interface, Audio in 2 supports microphone; 1 × RGB (output): Db-15； 1 × audio (output): fan; 1×RS232： DB-9； 1 × USB mini: software upgrade&remote control mouse; 1×RJ-45 ； Although there are so many interfaces, there is only one mini USB interface, which needs to be transferred to use the USB flash disk playing resources normally. In this case, it is strongly recommended that you give one away when you buy the product.
Youpai PJD6550LW's installation mode supports formal installation and reverse installation. The reverse installation needs to purchase a bracket. The formal installation also supports height adjustment. Some users may worry that such adjustment will lead to image deformation. Of course, at this time, we should mention a strong advantage of this projector, that is, it supports horizontal, up and down ± 30 degree trapezoidal correction. Even if the picture is side projection, it can still ensure the standard display of the picture.
Compared with traditional projectors, Youpai PJD6550LW has added some intelligent modules to support plug-in expansion, which can expand the wireless module projection module and provide foreshadowing for future intelligent module support. I have found modular support solutions on several products I have experienced before, but the price of this wireless module is not low. The deepest impression of Youpai PJD6550LW should belong to the protective cover I saw for the first time. In the past, too many connected cables would cause the back of the projector to be swollen. However, there has been no good solution. This time, I saw the solution with a shield on Youpai PJD6550LW, which is still very good. The space is large enough to not affect the cable routing, and the cable can also be left, right or bottom out. It has achieved good results in aesthetics.
Youpai PJD6550LW adopts the current mainstream high-definition widescreen projection resolution, 1280 * 800 pixels projection (the resolution is larger than the 1280 * 720 picture), which is more exquisite than the traditional 1080 * 768p projector, and its cost performance ratio is higher than the 1080p projector. Especially for home use, this resolution is the most suitable, which is easy to describe as inexpensive. At the same time, it provides 22000:1 dynamic contrast, supports multiple image scale adjustments, and has a built-in 190W OSRAM ultrahigh pressure mercury lamp with brightness up to 3300 lumens. The most noteworthy thing is that the Youpai PJD6550LW also supports the side projection function. Through its own correction function (vertical plus or minus 30 degrees horizontal plus or minus 30 degrees correction plus four corner adjustment function), even the side projection can obtain normal picture display, which is a very good function. 1.3X supports up to one point three times zoom; 10W surround stereo sound is also good.
After introducing the basic parameters of the product, we are now entering the performance evaluation phase. It is understood that the package price of this projector with the wireless module is 4099. This experience is equipped with the wireless module. The advantage is that it can achieve wireless transmission, and does not need data lines to transmit images. So we assembled the wireless module and adjusted the mode to MHL wireless mode. At this time, the blue signal light will be on, indicating that it has entered the working state, and then some information about the wireless module will be seen through the projection screen. Nowadays, many mobile phones support MHL mode, but Youpai PJD6550LW needs APP to achieve compatibility, which is a pity. Fortunately, the wireless module can support Android, IOS and Microsoft systems, basically covering mainstream system support. So there is no need to worry about system compatibility. There are two modes to realize wireless projection. One is to directly transmit to the projection device through the wireless module, and the other is to connect home routing transmission through the wireless module. The difference is that you can upgrade the connection between Youpai PJD6550LW and the external network, and the device side does not affect the Internet access, but also supports wireless projection. Of course, your home network speed is required to be fast enough.
A very interesting function, split screen display, is found in Youpai PJD6550LW, which is different from other functions. This function is realized through wireless modules, so it requires up to four devices to project through wireless clients. Since there is no such device on hand, the test will not be conducted. However, the official introduction can support up to 4 non fluid pictures at the same time. This is a new trend. The 300 inch screen can be divided into four sections at the same time. It's good to show some content. However, due to some technical factors, it is a pity that multiple videos are not supported. However, if four images are supported to play at the same time, it is believed that the sound part will give the manufacturer a headache, and it is also difficult to divert the transmission data. But there may be new breakthroughs in the future.
I have experienced several large projectors before. Youpai PJD6550LW gives me the strongest feeling in picture correction. In terms of color expression, it did not lose to other competitors. The color reverts to gorgeous, and the brightness of 3300 lumens makes the whole picture bright and rich in layers.
The author randomly intercepts a picture to feel the performance of the picture after being magnified. The original picture has a resolution of 647 * 300. Because of the deviation of the image quality color after the camera takes the picture, the color displayed in the contrast picture should be several times stronger. This is no exaggeration. Enlarged to a projection cloth of nearly 100 inches, the picture is still moving, without obvious graininess. Now let's experience the excellent color reproduction ability of Youpai PJD6550LW through some actual projection pictures.
In the last picture, the author purposely found a picture with low definition on the Internet to feel the restoration ability of Youpai PJD6550LW. The picture is still moving after amplification and projection, and the color restoration is also quite colorful.
Next, we are concerned about the heat dissipation. As we all know, the biggest problem of the projector is heating. The author also conducted a surface temperature test on Youpai PJD6550LW. The room temperature is about 23 degrees Celsius, and the temperature for half an hour of playing is about 45 degrees Celsius. I believe that if it is in summer, the temperature should still be controlled at about 60 degrees Celsius. According to the author's experience with many products, the heat dissipation performance of Youpai PJD6550LW is good. This is also what many micro projectors can't compare with.
Official data say that the projection distance of Youpai PJD6550LW is 1-10m, 30-300 inches. In fact, the performance of Youpai PJD6550LW is far more than that. The minimum focusing distance is only 20cm, and it can also focus accurately. And the picture is extremely clear.
Now, if you want a product to sell well, you really need some excellent technical support. The unique feature of Youpai PJD6550LW is its trapezoidal correction and four corner adjustment function of ± 30 degrees in the horizontal and vertical directions. In some cases, your equipment may not be able to face the projection cloth directly, so would you rather bear to lecture with deformed pictures, or try to correct the pictures? At this time, I believe that many users in need will be willing to pay for the PJD6550LW; How powerful and funny is this correction? The author also made a GIF to show how strong its correction ability is.
advantage:
① Strong trapezoidal correction capability.
② Large brightness and high definition;
③ Strong color reproduction ability
④ The price is moderate, and the wireless module increases the playability.
⑤ Good heat dissipation effect
Insufficient:
① Compared with micro investment, it is not intelligent enough, and the module is relatively single, so new functions need to be developed.
② The lens is not provided with a protective cover, Care should be taken in carrying.
③ , The standard USB socket is missing.
④ The performance under strong light is much lower than that at night (common fault of projector).
Well, at this point, the regular content evaluation of Youpai PJD6550LW is almost enough. As a commercial and household dual-use product, the 1280 * 800 resolution positioning is very accurate. In the market, SVGA is the 800X600 resolution projector on the market, and the price is generally around 1500~2000; XGA is 1024X768 on the market at present, which is generally about 2500~3000, while WXGA is 1280X800 resolution, which is generally about 3500~5000, while 1080p is relatively high-end at present, with product prices ranging from 5500~10000. Some friends will say that the price of the mini projector is cheap and the resolution is good, but another important factor is the clarity, which is affected by the brightness (unit lumen). The higher the brightness, the better the picture quality and anti-interference. Youpai PJD6550LW has a projection brightness of 3300 lumens, which is currently priced at about 3500, and the wireless module is priced at over 4000. The price is medium and low. With strong trapezoidal correction ability and excellent heat dissipation ability, it still has good market competitiveness.
