Hey, do you think it’s easy to hold an event now? Two days ago, my friend's company held a press conference, and the large LED screen he rented suddenly went black. He was so anxious that he almost had his chest broken during the live performance. Today we are going to chat about, how should we choose the LED screen for this venue?

1. Finding a supplier is like going on a blind date, it depends on the "hardware conditions""

Don’t just listen to sales bragging, ask three things first:
​​1. Does the production workshop have ISO9001 certificate?​ ​(This is equivalent to the company’s ID card)
​​2. Can the monthly output exceed 10,000 square meters?​ ​(Temporary additional orders due to insufficient production capacity will be charged an additional fee)
​​3. Is the warehouse stocked?​ ​(Last year during Double Eleven, a company spent an extra 80,000 yuan to temporarily replace screens.)

Here’s a little trivia: Manufacturers that engage in foreign trade are often more reliable. After all, factories that have passed EU CE certification have stricter quality inspection procedures. For example, I have seen a factory that supplies products for the Tokyo Olympics. Each screen must undergo a 72-hour aging test.

2. Don’t be fooled by the technical parameters. Remember these three numbers.

​​① Refresh rate must ≥1920Hz​ ​——Below this number, the camera will show all water ripples, and the photographer will fight you tooth and nail
​​② Brightness should be automatically adjusted​ ​——Adjust it to 5500cd/m² during the day to make your eyes bright, and lower it to 1200cd/m² at night to avoid dazzling your eyes.
​​③ Protection grade at least IP65​ ​——During the heavy rain at the Shanghai exhibition last month, all three screens that did not meet the standards were flooded.

Here’s a money-saving tip: Choose a belt​ ​Intelligent temperature control system​ ​screen, you can save 40% on electricity bills in summer. Last time there was a music festival in Hangzhou, I saved 28,000 in electricity bills with this function.

3. Pay close attention to details in contract terms and be careful about hidden costs.

The most embarrassing case I have ever encountered: a company did not pay attention to the transportation terms when signing the contract. As a result, the screen body was transported from Shenzhen to Beijing, and the crane fee alone cost an extra 12,000. Remember these required terms:

• Does construction and dismantling include labor costs?
• Sudden failure response time (it is recommended to write down "arrive within 2 hours")
• Rain and snow weather protection plan

Special reminder: Ask suppliers to provide​ ​Alternate Mod List​ ​, last year’s Double Eleven party was saved with 5% spare modules.

4. Don’t be a hands-off shopkeeper during on-site debugging, keep an eye on these three areas

1. ​​The total power of the power supply leaves sufficient margin​ ​: Add 30% of the distribution line according to the nominal power. Last year, an exhibition in Chongqing burned the distribution box due to insufficient power.
2. ​​Double backup for signal transmission​ ​: HDMI cable + wireless transmission are connected at the same time to avoid the embarrassment of a black screen when the leader is speaking
3. ​​Safety fasteners must be inspected with your own eyes​ ​: The most outrageous thing I have ever seen, the 8-meter-high screen is fixed with plastic ties

There is a true story: At a press conference, because the connector model was not checked, the Apple computer could not be connected to the large screen. The host had to use his mobile phone to cast the screen...

Let me tell you, renting an LED screen now is like buying insurance. Pay more attention in the early stage and shed less tears on site. Recently I have discovered a new trend - more and more companies are starting to choose​ ​Quick disassembly and assembly of screen​ ​, this style with a magnetic interface can disassemble and assemble a 200-inch large screen in 10 minutes, which is 3 times faster than traditional methods. Next time you see a rental screen with an aviation aluminum box, remember to ask: "Is this box waterproof?" "Make sure your suppliers think you know your stuff!
