Polar meter H1 VS LGPF1500 evaluation intelligent micro-casting matchup

As a major global manufacturer of home projectors, LG has always been a leader in the intelligent micro-investment industry and a favorite brand for many users. Last year, a friend of the company scouted a LG PF 1500. At that time, a total of about 7,000 yuan was spent, but The picture is really good, after all, it is 1080P full HD, also known as 1400 ANSI lumen brightness, but the purse silver is limited, can only be envious of the first, until this year in March the domestic leader in the production of projection brand polar meter H1, its hardware parameters compared to LG PF1500 and No less, but the price is only 4999 yuan, in full compliance with the needs of the start, by the way borrowed friends PF1500, some comparison, see the results, friends decided not to blindly worship the foreign brands, in the end what happened, together Comparing the evaluation of the meters H1 and LG PF1500.

The product appearance aspect Miji H1 was designed by a well-known South Korean design team that won the German iF Design Award and the Red Top Product Design Award. It inherited the classic design concept of the early Bauhaus form follower function and adopted a minimalist cube shape, showing a stable and generous appearance. While the LG PF1500 is more traditional in appearance, the cuboid shape uses more arcuate designs that look small and delicate.

The size of the H1 is 200×200×120mm, and the weight is 2.1Kg. The silver and black are used together. The side shell is a one-piece magnesium alloy. After anodizing and nano-injection reinforcement, the middle and lower parts adopt a large-area mesh. Decoration, from the front can see its internal Harman Kardon double 45mm speaker unit sound hole.

At the top of the fuselage, set the button area, and adjust the volume by sliding the sensor bar to the left or right. The previous, next, and favorite are touch keys, and the playback and pause are physical buttons.

The upper part on the back is the heat dissipation area and the lower part is the interface area. Its unique air duct can enhance the heat dissipation effect. All interfaces include one USB 2.0 port, one USB 3.0 port, one HDMI 2.0 port, and one HDMI ARC port. One fiber port, one 3.5mm audio output port, and one RJ45 network port.

In addition to the large area of ​​the cooling grille, the bottom most obvious is the two passive diaphragms built by Harman Kardon, the four feet are fastened with bolts, and a rubber cushion is added to the foot contact surface. Can play a non-slip and reduce the effect of resonance.

LG PF1500 dimensions 132 x 220 x 84mm, weight 1.5Kg, looks longer, the body is all white, the whole machine uses plastic material to make this high-end machine a lot of price.

The front only distributes the light source lens and the circular heat dissipation grille, and the two sides also distribute a large area heat dissipation grille, and the internal sound unit can be seen from the grid hole.

The interface is located on the right side and behind. In addition to traditional interfaces such as HDMI, fiber port, USB, RJ45 network port, 3.5mm audio port, etc., this machine also has many traditional interfaces such as RF port, component HD input, and AV input, but as a Taiwan's smart micro investment products have a very limited frequency of use.

At the bottom, two rubber pads are used for anti-skid and shock-absorbing. At the same time, a special screw hole is also provided at the bottom for lifting or tripod support. With the four corner fastening screws, it looks slightly messy.

The two design styles are dignified and prudent. They are small and exquisite, but they are not well cooked. The so-called "radish cabbage, each has its own love", and aside from the difference in design style, the products are designed on timber and humanized. The next effort will better reflect the value of flagship products.

Put the two together, the PF1500 is more slender, H1 is more square, PF1500 has a certain advantage in portability, mainly H1 increased more powerful audio unit, but the timber and workmanship, more meters H1 Significant grades.

In terms of the body keys, the H1 has a volume slider, media player, and favorite function keys, while the LG PF1500 has multi-function arrow keys. Obviously, H1 has better support for video playback, and the PF1500 is closer to traditional projections. The versatility, which can also be seen from its manual zooming and focusing methods, and polar meter H1 uses remote control electric focus and manual zoom.

Interfaces, LG PF1500 is quite comprehensive, although many interfaces are actually faced with elimination, but this allows the product to adapt to a wider range, and Mi Mi H1 boldly discard the backward interface, for HD players, SPDIF, HDMI ARC, RJ45, USB3. 0 These interfaces are really needed.

The retractable front leg support of the LG PF1500 is also duplicated from the traditional projection, and the four feet of the pole H1 foot can be used to fine-tune the corners, or to remove the hoisting adapter plate, which is practical and clever.

Accessories, PF1500 interface more, equipped with a high-definition extension cable and AV adapter cable, the document is also a thick stack, as well as drive CD, but these are flowers, H1 more real point, with Mango TV year VIP card , equipped with a MicroUSB charging cable and reset thimble for the smart remote control.

Both products use smart remote control, with flying squirrels, voice and other functions. Relatively speaking, the remote control of the Mi Mi H1 is more concise, in line with the design ideas of the Internet era remote control, through the bottom of the switch button, you can carry out electric focus, and Using the built-in rechargeable lithium battery, the LG PF1500's remote control looks a little evil and uses a pair of AAA batteries to power it. The function is based on the LG smart TV remote control design.

The size of the power adapter is not much different between the two products, H1 output is 19V 7.1A, and PF1500 is 19V 5.79A, because PF1500 is not officially listed in the country, so this Haitao back the product, its power plug is Korean Pins, but finding a universal jack is not difficult.

Polar Mi H1 adopts an intelligent system based on Android depth customization, which belongs to a relatively mature network STB-like system. The LG PF1500 adopts a WEB OS-based smart system. Both are resourceful, and the Android system is basically successful, although WEB OS system. There are also some of its own characteristics, and most of LG smart TV is also stubbornly adopting WEB OS system, but without the support of resources, even the best system can not play a role.

The PF1500 system uses the block diagram main interface. On the left is the program source preview screen. On the right is the application list. You can see the recently running application Youtube. After the bottom My Apps is opened, all the application lists will pop up. The number is small, many of them are from the system itself. With the function of the band, and not seeing the application store, it can also be seen that the positioning of the PF1500 itself is based on an external video source.

As the same product of LG smart TV system, the PF1500 is also quite comprehensive. It adopts a floating paging interface, which is the same as on the TV. Its picture effects provide bright, standard, movie, sports, games and custom modes. Responding to different needs of the scene, but looking at the English menu is really strenuous.

As a high-end smart micro-projection, voice function must have, and the tragedy is that PF1500 does not support Chinese, although the recognition rate is OK, but the role of the Chinese environment is very limited.

This product uses Web OS system, its predecessor was Palm OS, a relatively early smartphone system, in the web browsing, you can open a picture-in-picture window, view the program source screen, with a more sensitive dynamic sensor remote control, compare Novelty, but the picture-in-picture cannot be globally pinned. It can be seen that the development of the system is not perfect.

H1's system looks more affinity and is similar to many network set-top boxes. It embodies a simple and efficient design concept. The operation is clear and efficient, and the included smart remote control supports the flying mouse and gravity sensing operation. Can be opened.

GMUI system based on Android 5.1 depth development can install a large number of applications, suitable for home entertainment and business use of various needs, through the cooperation with Mango TV, networking of various video resources to see, in this regard PF500 is not a level.

Through the voice function of the smart remote control, you can search for movies, music, weather, stock quotes, and open applications, which are more practical than the PF1500.

Compared to the PF1500, which only has the upper and lower auto-correction, the left and right trapezoidal correction is also a practical function of the polar meter H1, and the projector can be placed at a larger angle.

With mobile phone APP no screen assistant, after connecting in the same LAN, you can achieve a variety of remote control operations, program push, and various functions in the treasure box, especially the same screen, screenshots and other functions, in business applications, very convenient.

Both models have a physical resolution of 1080P, but the LG PF500 nominal brightness reaches 1400 ANSI lumens, and the brightness of the metre H1 is nominally 900 ANSI lumens. The difference in data is a bit large, but the actual situation is surprising, all the following comparisons All are the same wall real shot side effect renderings, only the black edges are cut, and some of the original images and labels are added.

This comparison evaluation uses glory network set-top boxes as the program source, and transmits them to two projectors simultaneously through a 1×4 HDMI splitter, and uses the SLR to shoot the projection screen for comparison. Although this still has certain differences from the actual viewing, it is under the same conditions. Next, it can reflect the brightness and detail performance of two projectors to the maximum.

First of all, look at the comparison of a set of still pictures, it is clear that, in terms of brightness, the extreme H1 wins, it seems that the imaginary mark of the international manufacturers is not soft, and the picture is more transparent, the contrast is also slightly higher, more layered The picture saturation in the picture is higher than the original picture, and looks too bright. The PF1500's picture always looks like there is a layer of fog, not enough translucent, giving people a feeling of whitening, and the yellow color of H1 is closer to the original picture. It can be seen from the figure that the details of the mountains in the distance of H1 are still clear, while the PF1500 is slightly worse.

In the aspect of dynamic picture performance, we selected three types of high-definition movies, animations and TV series for comparison, and we can see that the light shot in the H1 picture cloud layer is clearer and shows better dynamic contrast, and the effect of animation is H1. Better color reproduction, pay attention to the unknown red sleeves, hair contrast, character skin color performance, PF1500 significantly darker, and white, H1 is more natural, contrast can see people and the woods layered H1 to be better .

The above screen is based on closing the curtains and turning off the lights. In the open window environment, the brightness of the two projections exceeds the expectation. In the room with bright light during the day, you can still see more clear images. Similar to the above results, H1 In terms of screen brightness and contrast, it still has obvious advantages. Especially in the environment where the curtains are closed, the sensory effect of the screen of the H1 is improved even more. During the shooting process, the video separated by the distributor is also found on the PF1500. The delay is bigger than H1, which will be reflected in the following video.

4K HD video playback, using LG home test video clips for comparison, PF1500 picture is cold, H1 picture is warm, PF1500's color feels a bit bluish, pay attention to the lower right corner of the LG Logo and background cloth color, picture H1 due to brightness and The contrast is high, the snow in the vicinity and the snow-capped mountains in the distance are more clear and natural. The saturation of various colors in the PF1500 is lower, and the H1 is more beautiful.

When using U disk directly hard solution to play, LG PF1500 can not play U disk high bit rate 4K high-definition video, and H1 can play smoothly, drag and drop no obvious Caton, visible H1 in 4K hard solution compared to PF1500 More powerful.

Some friends think that the extremely high-end audio unit is equipped with a high-end audio unit, which leads to higher product prices. This idea may be more accurate in the similar positioning products of the LG PF1500, and the high-definition video and audio frequency of the Mi Mi H1 is not a good audio system. The picture can only be a look at it, make clear the difference in positioning, plus the actual experience of use, we can understand why the Mi Mi H1 will use this combination.

Both projectors support Bluetooth playback. However, the Mi Mi H1 also supports the function of Wifi playback. Its audio resources come from Baidu. The number is very large, and it can also be played without a light machine, and it becomes a Wifi desktop audio system.

The bug recorded a video with two projectors and compared the effects. The audio source was sent to the two projectors via the network STB and the 1×4 HDMI splitter. Only one projector was turned on to the maximum and the other was muted. The same three songs were switched and contrasted. Since the use of SLRs for recording did not fully reflect the stereo effect of Mimi H1, it was enough to prove that such a design was not a chicken rib.

The result of the comparison is very obvious. The sound effects of the Mi-mi H1 are obviously deep, wide, and more layered, which reflects the higher level of the Harman Kardon sound. In terms of bass, the two bass passive diaphragms bring more powerful effects. This can be experienced in the "Home" and "California Hotel" in the audition of two songs, while the LG PF 1500's voice is relatively dry, high-pitched burr sense is strong, the bass part can be basically negligible, like the California hotel In the prelude, if it is not for the evaluation, basically there will be no interest in listening, but the audition of Tsienjian Ya’s “Stranger” also reflects that H1 is a little boring on the performance of Asian vocals. It is not enough to stretch, of course, for daily watching. For movies and music, this is enough.

Although the Polar meter H1 is equipped with a better audio unit, its power is 80~135 watts, and the power of the LG PF1500 is 100 watts. However, in terms of general energy consumption, its actual power consumption level is lower than that of the LG PF1500.

After about 8 hours of testing and tossing, the insects detected the heat of the two machines. Under the ambient temperature of 30°C, the highest temperature of the whole LG PF1500 was found to be the tail radiating hole, reaching 50°C. The temperature of the top surface is about 44°C. The highest temperature of the pole H1 is also in the heat dissipation at the tail, which is close to 44°C. The temperature of the side surface is only 32.3°C and the top surface is only 36.4°C. It can be seen that the heat dissipation effect is very good. For continuous use, it has better stability.

Sixth, summary

LG PF1500 and Mi Mi H1 are all flagship products of 1080P Full HD smart micro investment. Both have their own unique features in appearance. The level of workmanship is very good. H1 can be seen in the same environment, and the LG PF1500 can be seen in brightness. There is no high-level H1, and the H1 picture quality is better. In terms of sound, the Mi-mi H1 uses a better audio unit than the previous generation. With passive bass diaphragms, whether watching TV or listening to music, Can bring an excellent experience, the price, very Mi-H1 more close to the people, the current activity price is only 4799 yuan, for the more affluent friends at hand, Mi Mi H1 is undoubtedly a good choice.
