Immediately after the Chinese New Year, I wish you a happy New Year! Yes, precisely because of the occasion of the Chinese New Year, I only expressed time for the whole family to create this “pseudo home theater” and let Mom and Dad go home and feel the glamour and lazy time. Ever since, does TV buy good or buy small? Do you want to follow the "TV Spacing"? I use personal experience to share with everyone.

上面 The above picture shows the range of TV distances currently recommended by JD.

↑ This is the distance given by the media five years ago and it is different from the Jingdong version.

Speaking of the television pitch, this is an old-fashioned problem since LCD TVs were introduced more than 10 years ago. During the year and even now, each time I went to the store to buy a TV, the shopping guide must ask “How big is your living room or bedroom?” and “How far is your home TV cabinet or TV wall from the sofa?”, but the shopping guide recommended by the current and current The TV size is slightly different. For example, in the era when TV sets were very expensive, the shopping guideline was 5.2 meters; today, 60 inches is not new, and every household can afford it. Therefore, it is recommended that the viewing distance be 4.5 meters. ↑ This is the television distance given by the media five years ago and it is different from the current one.

In fact, the viewing distance is still that distance, the only change is just the concept of consumption. Just as Steve Jobs was holding the iPhone4's proud Xuancheng 3.5 inch as the golden ratio of smart phones, who now uses such a small mobile phone? In the same way, when super-sized TVs become less expensive and go into the homes of ordinary people, they should abandon the “view of distance” and buy the largest size under the same budget!

Nine years ago, my family’s first 47” LCD TV

The above is my parents' home. This was taken 9 years ago when I moved to my new home. At the time, I was a freshman and freshman. When I resold two mobile phones at the forum, I bought the 47-inch Hisense 1080P Blu-ray TV as a housewarming gift. It's still very proud to think about it now. At that time, the mainstream size was 32-40 inches. My living room was 4.2 meters deep. The viewing distance was 3.8 meters. According to the "recommended viewing distance," 47-inch TVs were purchased. There was a lot of discrepancies in the television sets of that era. The batches in the first half of the year were LG IPS hard screens, and later they shrank into soft screens made in Taiwan. I regret that this is a soft screen.

Now my parents' home has also put away an optoelectronic box and used an Android box. Speaking, the Android box is now easy to use and not expensive, with a 179 mini box millet, install a TV cat, you can watch thousands of large movies. Always observing the old idea of ​​watching radio and television, Dad also cancelled the radio and television cable in 2017 and was completely conquered by the Android box.

Three years ago, my house's 60-inch PDP plasma

In 2010, I owned the first house. At that time, people did not refurbish in the North Drift. After 13 years of attire, they bought a LG 60-inch plasma TV with a low price of 5555 yuan. Many valued friends are full of praise for that TV (should it be no stranger to it?). At that time, 60-inch domestic LED TVs were generally 7K+, and the price of this last-generation plasma really fell through the glasses. Yes, I was able to buy the biggest brand TV on the market at the time with the largest budget I could afford (within 6K).

At the time of the 42-50 mainstream era, the shock of this 60-inch TV set was huge. After six months of work, I lay down on the sofa bed after work to chase TV dramas and cooperate with the company that LeTV reported to be closed down. The launch of the Android box, and spherical Bluetooth stereo sound, watch 1080P HD movies and TV shows every day, enjoyable.

What I find hard to forget is that the base of the LG plasma can actually turn, which is equivalent to the effect of the adjustable wall-mounted steering. When you eat, you can turn the TV to the dining table, and the family can watch TV while eating, instead of holding a rice bowl to the sofa to watch TV.

↑ However, it is a pity that plasma TVs suffer from reflection problems and burn screen diseases.

This year, the new house was replaced with a 75-inch LED TV.

In mid-2016, we decided to marry National Day, so we began the renovation of this new house. In order to save time and energy, we found a decoration company to get it. But home appliances and furniture are all ours. The above is a sketch of the decoration company's design. Sometimes I wonder if I would like to share my decoration experience for everyone.

↑ In May 2016, the video wall still looks like this, and sand has come into play.

↑ In June 2016, the walls were scraped and the walls of the TV wall were modeled.

电视 At the end of July 2016, the video wall took shape and the living room chandelier was installed.

↑ In August 2016, the TV wall was finished with good wallpaper, and the television cabinet was gone.

↑ After the new house was renovated, Daddy went to the front to clean up his health.

Online shopping æ’¸ wool? I can also dry the whole article

Into the TV shopping section, as a 7-year Jingdong users, 10 years Taobao users, my online shopping experience, shopping is almost always bargain-hunting. In terms of size selection, in order to create a home theater-like effect, I can budget up to 75 baht within 1 W, and 75 baht is a watershed between commercial and commercial grades. Within 10,000, Haier LS75A31 and Changhong 75G3 were both available. They are also the top-selling and second runner-up of the 75-inch TV. As for the price, at the time of 6.18 Jingdongdian Qingli, it was even more than 8,000 yuan. (Changhong 75G3 was taken as an example. At that time, the price of the shop was 9999, and then a PLUS member received a coupon of 1W-1K, which is 8999). Cost-effective seconds to kill music Millet micro whale flow, go see their own three 70-inch TV quotes.

↑ At first, pay attention to this Haier 75 吋 4K TV, the lowest price in history 8K+ (after vouchers)

Haier LS75A31 75-inch 4K Android smart network narrow border UHD HD LED LCD TV (gold) 11999 yuan Haier LS75A31 smart LCD TV, equipped with a 4K resolution (3840x2160) 75-inch wide color gamut A + screen LCD panel, electricity Business propaganda 6 picture shows this paragraph uses RGB true 4K LCD screen, 16:9 screen ratio, gold frame and base with all metal materials, stand or wall hanging are more beautiful. Hardware is equipped with Mali T720 quad-core image processor, built-in Andr Jingdong direct link to encyclopedia

后来 Later, I found this Changhong 75吋 4K TV, the lowest price 8999 (after coupons)

Changhong (Changhong) 75G3 75-inch 64-bit 4K Ultra High Definition HDR Smart Full Metal Body Flat Panel LCD TV (Metallic Gold) 14999 yuan Jingdong direct link

As for how to choose these two 75-inch TVs? At first, it was also a headache for many people! In fact, Changhong 75G3 in addition to the refresh rate of only 60Hz, the rest of the configuration fully exceed Haier LS75, such as HDMI 2.0, USB 3.0 and Bluetooth 4.0, there is no loss in Dafa 96-area matrix light control technology, support HDR 10 mainstream standards, equipped with UMAX audio Technology (90% of Dolby stereo speakers), and even more power-efficient secondary energy efficiency (which is now shrinking and is now also three-skill).

It's a pity that the new home was not renovated in June, and there was no place to buy it, and I thought that TV would only reduce the price and it wouldn't go up. Therefore, no decisive shot caused regret. In the second half of the memory industry and the television industry, everyone understands. Until the basic decoration of the new house was completed in August, the news that the price of the TV panel was about to rise was just in time, and Jingdong pushed another exclusive offer (12,999 yuan), so it took a decisive shot.


It was also good luck. At that time, the exclusive price for me was 12999. Then I received a full 1W-1K voucher, and participated in the "Boil 8.15" event, sending a 1999 Samsung vacant, equivalent to It took 9999 yuan for the television and it will control the cost within 10,000 yuan in disguise.

PS: Today Changhong 75G3 maintains a long-term 14,999 yuan.

The point is coming, start talking about the next 75 TVs

With such a large TV, the box is much larger than the door. I think the comments all said that two masters were sent to the door, and some places even sent four masters to lift upstairs (old houses without elevators), and I was here to deliver one master chef, sincerely admired his “technique”.

Because I do not intend to wall, and summon Changhong after-sales installation base to charge 50 yuan, I feel no need to pick up the money, so let Jingdong courier together unpacking inspection, screen nothing let him go.

↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑ ↑.

Give the pedestal a close-up, this is the most common "Half-moon machete" pedestal, the design sensation is much worse than the early streamer base of LeTV Super TV and the boat-shaped base of LG flagship TV, but it is as stable as Mount Tai.

Personally think that the thickness of the TV can affect the "grade", in the store to see only 5 mm of Dafa 4K flagship TV, instantly feel tall.

Since a large TV is used to create a home theater, there are some important indicators that are easy to overlook, besides screen size, USB 3.0 and HDMI 2.0. First of all, the USB 3.0 interface ensures the stable power supply of the mobile hard disk and the smooth transmission of 4K high-rate movies, while HDMI 2.0 can achieve 4K 60Hz refresh rate. This is also the failure of Haier LS75 TV, the screen panel supports 120Hz refresh rate, the resulting HDMI interface is 1.4, is completely waste.

Changhong 75G3 equipped with a Bluetooth 4.0 remote control is worthy of praise, in the winter hand holding the remote control pocket can be "blind", simple button design reflects the essence of Internet TV. The CAN F55S, which also advertises itself as an Internet TV, is a bit of a pit father. The TV has a Bluetooth 4.0 function, but it is equipped with an infrared remote control.

看 Take a look at the effect of the video wall. There are two sentences - the TV sets are large and the TV cabinet is small.

↑ This is a trial audience after installation. This small Teddy is deeply attracted by television.

Began to create "pseudo home theater"

I'm glad that you can insist on seeing this. In fact, the idioms just started to haha.

With a 75-inch 4K TV to build a home theater, to solve the storage problem of 4K sources, I bought 2 1T hard drives + boxes, but the cost is more than 700 yuan. Then there is the problem of watching the distance. In fact, the distance of 4 meters from the TV to the sofa is too far away, which will weaken the visual impact. So he spends 270 blocks of lazy chairs in Ma Yunjia and puts it in front of the TV. In addition, the Fiji K2 wireless router, you old drivers understand. As for why not have HIFI speakers? Behind the facts do not need to be.


The distance between the new house living room is 4.1 meters, and the distance between the sofa and the TV is about 3.5 meters. This distance is actually too far away to achieve the shocking effect of a home theater and to find a way to get closer.

Multifunctional lazy sofa tatami single bed creative folding Bay window leisure armchair back lounge chair mail 278 yuan Taobao direct links

So, this set of 270 yuan lazy folding floor sofa, the screen is in sight!

Sitting in front of the TV to watch, must meet the 4K super clear source (if 1080P is boring, so close to see the pixel matrix). And an authentic 4K tens of GB capacity remotely, I used two 1T hard disk (Jingdong 700 yuan) + 2 boxes (Jingdong 40 yuan) to store, the cost is cheaper than the finished mobile hard disk. Of course, Jingdong's cheapest 2T finished mobile hard disk is still only 5XX yuan.

Yijie (EAGET) E600 2.5 inch USB3.0 high speed shockproof mobile hard disk 2TB silver 579 yuan Jingdong direct link

However, downloading 4K sources is a long process. I have 100M telecommunications fiber and Thunder VIP members. Sometimes 4K movies can break through 10MB/s, but most of the time they are like this. I really want to die. Now.

↑ Changhong 75-inch TV's expansion interface is very simple, mobile hard disk plug and play.

↑ Three folders were built, 1080P is a US drama, 4K is a movie, and it can identify Chinese directories.

↑ Support ASS, SRT and other subtitle formats, not afraid of the original 4K movie without Chinese.

4K film sources are relatively rare, but there are still a lot of really looking for. At present, I have more than 40 4K films, of which the most shocking is the "Pacific Pacific." Everyone can see some key information I marked, one is HDR for video, the other is DTS for audio, and the other is capacity up to 61GB, and the screen is 75 frames full. At night, turn off the lights and watch in the lazy chair, and turn on the UMAX theater mode. The shocking effect bombed the living room.

Originally, I wanted to buy a TV to try the local audio system, and then consider whether to use HIFI independent amplifier. The result was completely conquered by this UMAX theater mode. After the switch, there are two upgrades. First, the screen warms up in color, and it is more comfortable to watch for a long time. Second, the sound effect instantly enhances N grades. The treble bass fully erupts, and the sense of hierarchy is very strong. It feels a few more horns out of thin air. Subwoofer ah. Although still not comparable to independent HIFI audio, but definitely enough to see the film, just to see Lu Yu interview Zhou Hongyu, his family has a set of authentic home theater, is a professional-grade cinema projector plus no array HIFI amplifier to build, Nepal Ma had to press a dozen or so switches to open a machine. During the interview, he took half an hour to toss.

I suddenly realized that there is no end to the desire. It is best if you can use it.

↑ Native support for audio track switching, but still not in Chinese? Look down

å±… Actually support external Chinese subtitles, and is compatible with almost all subtitle formats.

↑ As a result, my wife completely incorporated my lazy chair and occupied my TV.

↑ WC, late in the day before yesterday, found that the old man secretly watched the film and the chicken shook hands when he sneaked.

["0" dollar purchase] [buy send 399] Fiji K2 1200M Gigabit home dual-band smart wireless router wifi through the wall 399 yuan Jingdong direct link

Fiji K2 to make a soy sauce, this shameless, wrong is not a four-antenna dual-band router, use it really good (in addition to the 5G band is easy to drop outside). I bought a 7-gigabit Ethernet cable (not a frozen chicken, only 7.9 yuan) and even TV. With the built-in system, I watched pseudo-4K movies online without buffering. I watched TV live streaming.

↑ Changhong 75G3 native Android 5.1 kernel, system upgrade can apply for beta testing qualifications, learn millet it?

The current purchase can activate the Tencent video VIP for a month, but focusing on Amway TV cat software, the cat can directly capture the entire Internet video resources, but also automatically remove the title and the end of the film, I intend to expire after VIP Return to the TV cat's arms. And the point is, Changhong 75G3 can set APP boot, this is the function of Internet TV shield such as Xiaomi, that is to say I can disguise the TV cat as a native system to use it.

Originally, I took a lot of professional test photos, but I thought that after all, it was not a TV evaluation, so I had to delete it all. Only the above group of pictures are left. Changhong 75G3 under the black screen, there is still a dark spot phenomenon, after verifying that this screen is a soft screen Innolux, the advantage is the secondary energy efficiency. Objectively speaking, due to the fact that the panel is too large, the dark spot problem has to take a chance. There are buyers who will be much better after the replacement. I don't want to toss it out of control, and it only appears in pure black background.

↑ I've seen people in the market, and the static screen effect isn't as good as it is!

Finally, every time we talk about home theater, there are always people who recommend the projector + curtain + HIFI speaker program, but a word to "projection party" convinced - do you dare to open the curtains at home to watch movies in the daytime? Personally, under the premise of pursuing results, 100 吋 recommends 3000 liter, 120 吋 recommends 4000 流, and 150 建议 suggests 5000 流. However, even with such a high degree of brightness, once the curtains are opened during the day, they are immediately scared. Can cast the viewing time into night.

For the 75-inch 4K LED TV, the sun can watch movies in the sun during the winter. In addition, my 75-inch TV is a matte screen, there is no reflection of the 60-inch plasma glass panel in the past, we can pay attention to the next screen material (matt screen> bright screen> glass screen).

Finally extend two more ideas

1: Personally think that 75吋 is a watershed between civilian and commercial grades, even if the price of a big 5吋 (80吋) is doubled, Jingdong 75吋 still has a million or so (such as Haier 1W1-1W2, Macallon 1W floating), Jingdong's cheapest 80-inch (such as Sharp 80X7000A) at least 3W, so 75-inch is the maximum size that the common people can accept. If you believe that "the same budget to buy the largest size," 75 at the present stage reached the top.

2: The banner of millet, music, and micro-whales under the banner of Internet TV has already reached the stage of low-cost market share. It is mainly at the stage of cost-effectiveness. At this stage, the price of TV in their home is not cheap, such as the current minimum of 60吋m3S. 4699, and Skyworth Cool Open 60-inch new 60N2 also only 4199-4399 floating, panel and configuration cool open also beat Xiaomi 3S. Therefore, we may wish to pay attention to the TV industry's domestic and old (the first step Skyworth, Hisense, Changhong, the second ladder Konka, TCL, Haier, etc.), and their Internet brands (Cool, Mocha, Marshal, KKTV, etc.).

Why don't you write it? We'll write it here. Welcome everyone, don't like it!
