Why! If you don’t have a cool big screen when you hold an event now, you always feel that the venue is almost interesting. Last week, my friend held a concert, and it took half a month to choose the stage LED screen.——​ ​The brightness is not enough for the audience to scold the streets, the refresh rate is low, the live broadcast is overturned, the wrong size is selected and the money is used to make money​​...Today, let’s break the tricks of this industry and talk about it!

1. Is it really necessary to use a large LED screen?

You might mutter:​​"Isn't the projector smelly? Do you have to mess with this money-burning thing? "​ ​
To be honest, LED screens have long been standard for any performances of a certain scale. To give a real example:

• ​​The texture of the picture is swaying projection​​: When encountering direct lights, the 7500cd/m² high-bright screen can still illuminate the idol's face clearly
• ​​Play with black technology on stage​​: For example, using a transparent screen as the background, the singer "breaks out of the wall" from the screen"； Or use a curved screen to create a 360° surround effect
• ​​Save money on set​​: Many music festivals now use LED screens as the main body of the stage, and the lighting and stage design fees can be cut by 30% or 40%

But then again, if your budget is less than 50,000, or the site is less than 15 meters deep, there is really no need to force it. This is just like buying a sports car - it depends on your strength!

2. How to choose the three core parameters?

▍Don't get tricked in brightness

Here is an industry unspoken rule:​​Outdoor screen brightness must be ≥5000cd/m²​​, otherwise there will be a blackboard under the sun! But the brighter the better, the better——

• Concerts often use 6000-8000cd/m²
• Theater/conference hall is enough to choose 1200cd/m²
  ​​Test tips​​: Take a video with your phone facing the screen. If there are obvious flickering stripes, please exchange it!

▍The refresh rate must be hard-core

​​1920Hz is the pass line​​, below this number...
→ The live broadcast screen is full of water ripples
→ High-speed sports lenses are pasted into mosaics
There is a simple way to judge: use the camera shutter speed to 1/1000, and you can only be qualified if you don’t have black bars when you take pictures.

▍The protection level is vague

Regardless of indoor and outdoor,​​IP65 protection is the bottom line​​! Last year, a music festival had a short circuit on a rainy day and directly compensated the organizer for 300,000 yuan...
​​Three points of focus​​：
✅ Sealing strips at the joints of the box
✅ Power supply interface with waterproof cover
✅ The back heat dissipation hole has a dustproof net

3. The money-burning trap that is easily overlooked

▶ The bigger the size, the better

Remember this formula:​​Home screen width = stage width × 0.6​​
For example, the 10-meter-wide stage is the best visual effect with a 6-meter-wide screen. Don’t believe the nonsense of “the bigger the more grand” – the extra area is a waste of money!

▶ Transportation and installation hides thunder

​​Real cases​​: A company moved it by itself in order to save 2,000 yuan for freight, but it ended up breaking three boxes and losing 80,000 yuan...
​​Pit avoidance guide​​：

• Choose a rental service with airbox
• Requires the supplier to provide installation insurance
• Measure the height of the site door in advance (the box thickness exceeds 20cm, and may not be able to enter the elevator)

▶ Content adaptation costs life

The most outrageous scene of crashing:

• The vertical video taken with a mobile phone is directly cast, with half of the black sides on both sides
• 4K video is not transcoded and causes it to become PPT
  ​​Must-have list​​：
  ✔ 16:9 horizontal video source
  ✔ H.264 encoding format
  ✔ Make warm field circulation materials separately

4. Soul questioning: rent or buy?

​​I've been asked this question less than a hundred times​​, directly follow the comparison table:

​​Focus on​​: Unless you are the top performer in holding concerts every day, renting is definitely more cost-effective!

Editor's opinion time

After eight years of activity planning, I said a few words from my heart:

1. ​​Book three months in advance​​! Especially for small-pitch screens below P3, you can't get it in peak season
2. ​​Key tests during rehearsal​​: Let the most picky people sit in the last row to see the effect. The lighting engineer and the console must be coordinated in the same room.
3. ​​Don't save money on technical support​​: I have seen too many screens to choose miscellaneous brands to save 5,000 yuan, but the screen was restarted on the day of the event - this money saves you a lot of money!

Finally, I would like to remind you of cold knowledge:​​The stage LED screen rental market soared by 37% in 2025​​, but high-quality equipment is still in short supply. So, if you meet a reliable supplier, you must firmly grasp it. Good equipment is harder to find than boyfriends these days!
