Hey, brothers, have you encountered this situation too? When I saw the cool background wall of someone’s home when I was watching short videos, I felt itchy and wanted to make a comedy, but after searching the Internet, I was confused? There are quotes ranging from thousands to hundreds of thousands of yuan, and the parameter list makes people dizzy. Today we will break it apart and talk about how to choose this indoor LED screen so as not to be fooled!

1. First understand what you are going to do

Although they are all luminous boards, they are not used in different scenarios at all. Last month, I made a joke when I helped my friend decorate his e-sports room. He insisted on playing games with the screen used in the conference room, but the result was that the shadow was as serious as PPT.

​​The three mainstream demands are selected​：

1. ​​Home Video​​: It is enough to choose P2.5-P3 spacing, too big and strong grainy, too small to burn money (just like watching 720P videos with a 4K screen, it is a waste)
2. ​​Shop display​: It depends on the traffic. A milk tea shop with an average of 500 people per day uses 800cd/m² brightness enough. Don’t listen to merchants fooling the outdoor brightness.
3. ​Corporate Conference Room​: Focus on the refresh rate. Only by starting at 1920Hz can the video conference not be flashed (I have seen some companies buy the wrong screen and start remote meetings and all employees turn into ghosts)

2. What are the tricks hidden in the parameter table

Once, when I accompanied the customer to the market, the merchant came to "Our screen can pass on three generations", and the warranty period was only 2 years. Remember these key parameters and don't be fooled:

​​Brightness Trap​：

• Don't buy indoors with more than 1500cd/m² (the same principle as using a searchlight to shine your eyes)
• Intelligent adjustment function must be (the brightness changes automatically in the morning and evening to be comfortable)

​​Resolution metaphysics​：

• P2.5 is available for viewing distance of 2 meters, and P3 is enough for 3 meters (just like a mobile phone film, you can’t see scratches when you are far away)
• Don't believe in the word "4K level display", LED screens are not standard resolution

​After-sales routine​：

• Ask clearly whether the installation and debugging fee is included (I have seen a screen with a quotation of 30,000 yuan, and the installation fee is 15,000 yuan)
• Modular design is very important (what lamp bead can be replaced separately if it breaks, and the entire screen does not need to be scrapped)

3. Guide to prevent pits from online and offline procurement

Last year, I helped chain gym chain purchases and broke into mines. I found that the color difference was serious after I installed the screens I bought online. Summarize these experiences:

​​Four must-check offline factory​：

1. Check whether there is an aging test area in the workshop (the good screen needs to be continuously roasted for 72 hours)
2. Will touch the splicing seam cut hands (poor workmanship can cut tissues)
3. Does it smell pungent (inferior material formaldehyde exceeds the standard)
4. Try the response speed of the remote control (don't ask for stuttering)

​Online purchasing three don't​：

• Don't click the link without actual test video
• Don't touch merchants who don't issue invoices
• If you don't explain the logistics method, hurry up and run

I have a cold knowledge: the workshop floor of a manufacturer in an industrial park in Shenzhen must be subject to anti-static treatment, and even the screws must be inspected three times. Although this kind of detail is invisible, it will be known if you use it for three years.

4. Expected experience of self-paying

When renovating the studio last year, I personally compared six suppliers. The most exaggerated one, the actual measurement distance of the screen marked P2.5 is 3.2mm, so the moisture can raise fish! Later, I chose a 48-hour copy machine. Although it was 15% expensive, it has zero faults until now.

​​Practical test key list​​：

• Take the phone camera to the screen (the black line indicates that the refresh rate is not enough)
• Play 10 minutes of pure white picture (with dark spots directly pass)
• 50 consecutive switches (test power supply stability)
• Touch the heat dissipation port with your hands (don't consider hot)

The editor says something real

If you ask me, buying an LED screen is like finding a partner, you can’t just look at your appearance. Some manufacturers make the parameters scattered, but they either use the color offset or the flash screen. However, there is a company in Shenzhen that is quite practical. They have to undergo 27 tests before leaving the factory, and even the packaging box needs to be tested for falling.

Recently, I have discovered a new trend - many merchants have started to engage in modular leasing. Just like you can't afford the entire screen, you can rent it by square meter, and it can be upgraded for a few months. This model is especially suitable for pop-up stores. I heard that there is a milk tea brand that relies on this and has changed six visual solutions in three months.

Finally, I would like to give you a tip: Don’t buy second-hand screens with cheap prices! Last week, I saw someone accepting a screen that closed down the KTV, but the repair fee was even more expensive than the new screen. Remember, a good screen is like a good knife. If you want to use it easily, you have to choose the right craftsman!
