The first sun LG PF1000U the first 1080P ultra-short focus LED home projector experience

Originally wanted to wait for the discount of the black five, the result waited until the first one dropped a little. In order to use it sooner, we will place an order. At the time of clearance, Glory was asleep at 500 softcoins. It is said that this is a fixed tax for projectors.

basic data

DLP projector, LED light source, 1000 lumens, 30,000 hours life. Contrast 150000:1. Resolution 1920 x 1080, pixels are normal (non-diamond). Supports quadrilateral correction. Supports 3D pictures (to use 3D glasses based on DLP-Link technology). Ultra short focus. Comes with two small speakers (3 watts each) and supports Bluetooth audio output. WiFi is supported.

It should be noted that the version of this machine in Europe and elsewhere is not the same. This projector itself supports digital television decoding (of course, the domestic do not expect), and Europe and the United States have different coding standards, so it specifically came out in Europe. The European version is equipped with an ordinary remote controller and the other version is equipped with Magic Remote. The advantage of this Magic Remote is that the mouse can be controlled by waving (but only used to operate the projector's own interface). In addition, the European version is also different in the interface, the European version has a USB interface and cable interface, a VGA interface. It is recommended not to buy the European version. After encountering the unstable WiFi, you find that you cannot connect to the wired network.

About ultra-short focus

This is an ultra-short focal projector. Note that the concept of "short focus" is different. The ultra-short focus technology focuses on a very short distance through a special light path so that the projector can be placed on a TV cabinet to project a large image. I used excel to make a simple projection size calculation based on the data in the official user manual <-- I'm the link

After the download opens, enter the data in the upper left corner of the green grid to calculate the relevant size information. The two right figures show the relative size and position of the projection screen and TV cabinet.

Considering that the projector is placed on the TV cabinet, we are concerned about the distance between the outside of the projector and the wall. That is, if your TV cabinet is placed on a wall, how deep the TV cabinet should be. Here are a few typical situations. At 11cm, the screen is 60 inches, which is the official projection of the nearest projection distance. At a distance of 38cm, the screen is 100 inches. This is the maximum projection distance recommended by the authorities. In theory, if you play farther, the screen will be larger, but this will lose the meaning of ultra-short focus.


Why various

Why buy projection instead of TV?

Because leaders have dry eye (this is issued by the leader's account), watching the TV screen for a long time will be uncomfortable to the eyes, but we found that when we watch movies, we don't feel bad, so we thought of buying a projector instead of a TV. Judging from the actual use in the past two months, leaders said that they did not use the LCD screen so much. And ... 80-inch TV or more... I can't think of the price...

Why not buy this one without buying other models?

First of all, the laser light source is too expensive. Then, those who do not have ultra-short focus need to consider the installation problem, and our new house is a developer who has done a good job, do not want to engage in major projects and do not want to go down the line, so we must choose ultra-short coke, and this can be before moving into a new house Use it in the current rented house. Next, non-LED light sources have also been ruled out, because we are afraid that changing light bulbs will increase costs and trouble. So the first thing that came into view was Philips:


Dual 11 back discount when more than 8K buy ~ right! This material is still my explosion

It was still good to use it when it was bought back, but it was found that there was a sound after the screw dropped. After all, it was 8K! After tangling it, he evacuated... After discovering the LG, a comparison was found to be much better than the Philips. The biggest advantage is the resolution: Philips is 1280x800, and it is arranged in a diamond shape. Now think about it, Philips' purchase of Taiwan has abnormal sound can be regarded as God's will ... ... experienced N times and an East tear X finally was able to return ... ...

It must be said that in addition to its value, Philips is a good speaker.

This is a picture taken before, we simply see that the value of Yan is still good

Turn on the light effect ~ Please note that this stuff is very heavy! ! ! !



Come, let's see LG~

First we come to LG PF1000U pseudo open box

In the office, my first reaction was that it was really small compared to Philips.

Get out of the box again!

Have you seen all of them?

Projector, various lines, manuals, remote controls, etc.

Also equipped with 2 remote control batteries

Wide voltage Do not need transformer ~ rod!

This remote has a somatosensory and leadership expresses cool

Reality is very small, especially compared to Philips

The amount is about 30.6×13.3×7.9CM

Various interfaces & icons

Plug it in! Plug it in!

LG PF1000U ultra short throw projector

First of all, I tried it free with the leading sims...

Yes, it's very frustrating, don't care about these details

This is about 80 inches of effect can look at the figure below the leader on the right edge of the paw

The above figure shows the distance required for an 80-inch projection.

The above picture is taken at night ~ I deliberately shot a black and white contrast during the day

The middle of the TV cabinet is the projector, and the left and right sides are 2 broken speakers.

What? Don't know the environment? Look at this

The disadvantages of this projector

Yes, yes, yes I know you have a lot of slots to spit, so I write the shortcomings first

First of all, as a disadvantage of the projector: the screen is white when the environment is very bright

Because the nature of the projection is to increase the illumination on the projection surface, but when the environment is very bright, the projection surface itself is very bright, and it is impossible for the projection to “cast black” to make the projection surface dark. The black technology that lightens the illuminated area seems to have only appeared in the robot cat's props. It really is a true black technology.

In contrast, LCD TVs have no such problem (of course I believe no one will use a headlight to look at a TV screen). So how to ease this shortcoming of projection? This requires a special projection screen.

If the projection screen itself is dark, then in the brighter environment it will be darker than the white wall, and it will have an improved effect on the black level. However, it should be noted that high-gain screens can improve performance in bright environments for non-ultra-short throw projectors, and not for ultra-short throw projectors. The principle looks like a high-gain curtain has a mirror-like effect on the side light, so that part of the ambient light does not enter the human eye as diffusely reflected.

Ordinary projector light is directly facing the projection screen, the impact is less, but ultra-short-focus projector light source position is very low, its light shines on the curtain at a very small angle, this time It will be reflected much like ambient light, causing the picture to be not bright enough. There is a kind of curtain for ultra-short-focus projectors, but they are usually sold with ultra-short-focus projectors from various companies. I only found one such item:

But I'm not sure whether this curtain and LG projector can be used together.

So from an economic point of view, only gray low-gain curtains can be used later. But fortunately, the new house comes with a sun roller blind, and when it is completely put down, the room interior will be black and it will not reach out.

The second drawback is caused by the ultra-short focus feature: very picky on the projection surface

Since the light source is very low, the light is projected onto the projection surface with a small angle. If the projection surface is not smooth (for example, it is projected on a white wall but the wall has small irregularities), a very small projection will result. On the other hand, if the projection surface is not flat (for example, it is projected on a white wall but the wall has large undulations), the picture will be warped.

In addition, if the projection surface is not flat enough, it will also make it difficult to achieve good focus throughout the frame during focusing. Ordinary projectors are not so picky because of the difference in projection angles. How to ease it? It is best to use a picture frame curtain or a pull line screen. These two kinds of screens can ensure the flatness of the projection surface. At this time, only the level of the projector itself needs to be adjusted.

The third drawback is the delay

It takes time for the display signal to input from the projector to the process actually reflected on the screen. This delay time is not a problem when watching TV movies, which are not interactive, and the delay time is short. But when you want to play the game, the delay of the default mode will be obvious. When you switch to Game mode, the delay problem will be improved. According to a reaction in a foreign forum, it is in the state of “there is definitely not yet obvious when playing the game”. . As far as our use of this period is concerned, the main bottleneck is the low frame rate caused by the computer performance of slag....

The fourth drawback is fan noise

When the environment is quiet, you will hear the sound of the fan in the projector. And when the content you watch has its own sound, the fan's voice is not noticeable. I generally notice only when the environment is quiet. But if you want to watch horror movies, then there may be a lot of quiet time, and the fan's voice may make you play... This is also a reason for foreigners to return after buying (one).

Digression, Philips is quite quiet


For people

If you meet the following conditions, you can consider buying this LG projector:

Looking at the LCD screen can be uncomfortable or require larger screens within a smaller budget. It is difficult to solve the problem of lifting and wiring of the projector. Do not want to face the traditional light bulb brightness attenuation and replacement issues. There is a certain requirement for the screen resolution (the screen with a resolution below 1920x1080 cannot be accepted), but there is not enough silver in the wallet (you cannot afford a laser ultra-short focal projector).

to sum up

On the whole, it was quite satisfactory. After all, it resolved the problem that leaders saw the uncomfortable eyes of TV. There was a big picture and the parameters were the best that could be obtained at this price point. Ultra-short-focus projectors for home use are still relatively few, and perhaps more products will emerge in a few years, and then there may be more cost-effective products.

Motion Control Sensor

Motion control sensor is an original part that converts the change of non-electricity (such as speed, pressure) into electric quantity. According to the converted non-electricity, it can be divided into pressure sensor, speed sensor, temperature sensor, etc. It is a measurement, control instrument and Parts and accessories of equipment.
