What should I do if I need a big screen for an event and I'm so anxious? The price of installing a display screen on the outer wall of the shopping mall ranges from 50,000 to 500,000. The water here is very deep! I just heard last week that a boss chose a second-hand screen because it was cheap. As a result, the screen went black on the day of the event and the customer was compensated 80,000 yuan in liquidated damages. Today we will break it apart and talk about where the doorway to this large outdoor screen is.

1. Finding the right person is more important than bargaining

Do you believe it or not? For the same display screen, a reliable supplier can save you 80% of your worries. Last year, a supermarket chain held its anniversary celebration and found an unqualified company to install the screen. As a result, it short-circuited and burned the circuit in the rain. The maintenance fee alone cost an extra 120,000 yuan.

​​There are three things to keep an eye on when looking at qualifications:​​：

1. ​​Have you seen the production workshop in person?​ ​? For factories with a monthly production capacity of over 10,000 square meters, equipment stability is usually not bad.
2. ​​Is there any hard-core certification such as ISO9001?​ ​? This is the same as looking at the health permit when eating.
3. ​​How many similar projects have you done?​ ​? It is best to find someone who has done complex projects such as stadium fences and screens.

To give a living example - a curved screen installed in a pedestrian street in a third-tier city. I first found a local small workshop, but after half a month of debugging, I couldn't complete the picture splicing. Later, I switched to a serious manufacturer and came with a 3D simulation plan, and the full arc display was completed in three days.

2. The parameter table is not a holy book, focus on these five items

Don’t be fooled by the salesperson’s jargon! Remember these key numbers to ensure you are not fooled:

1. ​​The brightness should be strong enough​ ​: Starting from at least 4000cd/m² outdoors, it can be seen clearly under the sun (don’t believe those imaginary numbers marked 8000, only the actual measured data counts)
2. ​​Don’t compromise on refresh rate​ ​: 1920Hz is the bottom line, and the captured video will not have ripples.
3. ​​The level of protection must be strong​ ​: IP65 is a life-saving talisman for outdoor screens. It is not afraid of rain or snow.
4. ​​Pay close attention to energy consumption​ ​: Hourly power consumption is directly related to electricity costs. Common cathode drive technology can save 30% of electricity.
5. ​​Maintenance should be convenient​ ​: Quick-release structure can shorten maintenance time from 8 hours to 2 hours

I have seen too many events fail - a music festival used a screen with insufficient refresh rate, and all the comments during the live broadcast were "screen tearing", which made the organizer's face turn green. To be honest, these parameters look complicated, but they are actually just a layer of window paper, which is easy to understand once you pierce them.

3. There is a lot of knowledge behind installation and maintenance

Do you think that’s it after buying a screen? wrong! Installation is the highlight. A certain building opened last month, and the screen body was actually good. However, the installation team miscalculated the load-bearing capacity and almost deformed the steel structure.

​​Be sure to avoid these pitfalls​​：

• ​​Professional foundation survey required​ ​: Don’t save the thousands of dollars in testing fees, especially in salt-spray areas near the sea.
• ​​Route planning in advance​ ​: Strong and weak currents must be routed separately. Signal interference is no joke.
• ​​After-sales response speed​ ​: A technical team on call 24 hours a day is more precious than gold.

To tell the truth - a large screen on the top of a mountain was installed in a scenic spot, but it was cheap at first and did not require regular maintenance. As a result, after half a year of use, the brightness decreased by 40%. The maintenance team went to the mountain for inspection and found that the cooling system had a thick layer of moth corpses. If you had signed a maintenance contract, this would not have happened during monthly inspections.

4. How to break the price fog

There are a lot of tricks on the quotation! A car company was deceived during a press conference. The transportation fee was not included in the contract, and in the end, the company paid an extra 38,000 yuan for the crane. Teach you three tricks to break the game:

1. ​​Want a full price list​ ​: Transportation, insurance, installation, taxes and fees are clearly listed one by one.
2. ​​Price comparison is better than the full set​ ​: Don’t just look at the price of the screen, the after-sales maintenance cost is the biggest factor.
3. ​​Read the deposit terms carefully​ ​: Equipment damage compensation standards must be written clearly in black and white

One restaurant chain brand was smart and signed a "billing based on screen time" contract with its supplier. Pay more when you use more during the opening activities, and pay less when you use less during the off-season. This saves you a little over 200,000 in a year. This flexible cooperation model is becoming more and more popular now.

In the end, I personally feel that choosing an outdoor screen is like looking for a partner - it's not enough to just look at appearance (display effect), but also to look at family background (corporate strength), personality (after-sales service), and stress resistance (product quality). I have seen too many events that were ruined due to poor after-sales service. To be honest, spending more money to buy a product with less worry is a good deal no matter how you calculate it. Next time you see a particularly low quote, be cautious - there may be a big pit hidden behind the bargain!
