Ouch hey! Yesterday, a guy who opened a gym was eager to find me: "No matter how you adjust the newly installed LED floor tiles, it looks like a layer of gray. Where is this parameter setting hidden?" This is the right question! Today I will take you to break through this window paper. I will ensure that after reading this article, you can be the "attendant physician" for the shopping mall large screen!

1. Parameter settings are not hide and seek

Let me give you a reassurance first:​The LED screen parameter settings are really not hidden in the corners​​! To put it bluntly, it is similar to adjusting the brightness of a mobile phone. The key is to find the right entrance. There are three main ways to open it on the market:

• ​​Remote control shortcut keys​​(It's like the remote control of the TV at home, and the menu will be released as soon as you press it)
• ​Control software interface​(The computer has a control software, and the parameters are all lying inside)
• ​​Mobile APP direct connection​​(Now all new screens can be remotely controlled by the mobile phone)

Last week, I was very funny when I helped the hotpot restaurant adjust the signature screen, and the boss couldn't find the brightness adjustment. Guess what happened? People use the remote control as an air conditioner and remote control to plug the bottom of the drawer! So,​Confirm what control equipment you have first​, don't roam like a headless fly.

2. Core parameter adjustment secrets

After touching the settings interface, don't be shocked by the numbers on the screen. Focus on these five "life gates":

1. ​​Refresh rate ≥1920Hz​​(The larger the number, the more stable the picture will be, and you won’t be dizzy after watching it for a long time)
2. ​​Intelligent brightness adjustment​(Indoor 800-1200, four or five thousand outdoors start)
3. ​​Grayscale level 16bit+​​(The color transition is natural like ink painting)
4. ​​Color temperature adjustable range 3000K-10000K​​(Switch warm light and cold light at will)
5. ​​Contrast ratio 5000:1 up​(Black can sink, white can illuminate)

I remember that I adjusted a batch of screens to an e-sports hotel last year. The guys insisted on pursuing super high brightness, but they adjusted it to 8,000 nits. I almost got blinded by the snow map when I played with chicken. Later, according to the manufacturer's​Intelligent brightness solution​​, made presets based on different game scenes, and now customers praise it as "more than their own monitors"!

3. Environment adaptation is the real skill

It is better to be good at adjusting the parameters well! Here's a special place​The right time, place, and people​：

• ​​Indoor venue​: Focus on anti-glare, brightness should not exceed 1200, color temperature is recommended to be 4500K
• ​​Outdoor advertising​​: To withstand the sun, the brightness starts at least 4,000, and IP65 protection must be enabled.
• ​Stage performance​: The refresh rate must be upwards of 1920Hz, or the lens is full of water ripples when scanning the lens.

There is a lesson that must be told from blood and tears! A bar owner had a cheap picture and used the indoor screen as the background of the stage, but the camera shot was full of flash screens. Later, I changed my professional rental screen and not only did I carry the aluminum, magnesium, zinc box, but I didn’t know how to use it.​Quick disassembly and assembly design​Save the tour team a lot of time. So,​The parameters must follow the venue​, something must happen if the hard-supported template is!

4. Hidden function to bottom out

Nowadays, LED screens are no longer "silly", and they hide a lot of black technology:

• ​​Timed tasks​(The screen will automatically turn on at 8 o'clock in the morning and the lights will be turned off at 10 o'clock in the evening)
• ​Split screen display​ (Play a promotional advertisement on the left, and live broadcast of the ball game on the right)
• ​​Fault self-test​(When the module is broken, it is marked out in the red box)
• ​Energy saving mode(It will automatically adjust the dimness and save power when no one passes)

I saw awesome operation last month! A shopping mall’s transparent window screen plays the “combination of virtual and real”. The daytime transparency is 86% and does not affect lighting. The advertising mode is automatically switched at night. What's even more amazing is to use it​Intelligent photosensitive technology​, the sun gets stronger and the screen becomes brighter and there is no need to manually stare at it.

5. After-sales guarantee cannot be missing

What should I do if the parameters are messed up? At this time, we can see the manufacturer's real skills! Reliable needs to be:

• ​24-hour technical response​(You can find someone if you have problems in the middle of the night)
• ​Remote diagnostic system​(Cloud consultation can be done by connecting to the Internet cable)
• ​​Insurance from three years​(It is true confidence to dare to protect for so long)
• ​​User training​(Let’s teach and teach, if you don’t learn, continue teaching)

I met an old Tie Tei who was in an auto show. Once when he was moving in a foreign exhibition, he changed the color parameters. Fortunately, the manufacturer's technical team was rescued by the remote control of the hot spots of the mobile phone. If this is unreliable, it is probably necessary to perform monochrome screen performance art on the spot!

Finally, let's say something real

If I ask me, adjusting the parameters is like adding salt to stir-frying dishes-​​The most important thing is that more or less is bad things​! I have seen too many people regard parameters as transcripts and insist on refresh rates to the death. In fact, like the fenced screens of professional stadiums, we should give priority to it.​Viewing angle and protection level​, after all, you have to see clearly from all angles in the audience.

Recently I heard that a Shenzhen factory has created a "fool mode" and packaged all the parameter presets for common scenarios. The mall chooses the "advertising mode" and the theater chooses the "performance mode". Even e-sports hotels have exclusive configurations. ThisMake complexity simpleThe ingenuity of thinking is the most thoughtful design we novice needs. Remember, a good screen depends on adjustment and seven points to maintain. Finding a reliable "technical backer" is better than anything else!
