Do newbies who are new to LED displays often worry about the screen - where should we set these subtitles? Don’t panic, today we will break it and explain it clearly. Just like a novice learns to ride a bicycle, you can get on the road in half an hour as long as you master the method!

​Let me tell you a real case first​: Last month, a boss who opened a milk tea shop spent a lot of money to install an LED advertising screen. As a result, because he would not change the promotional information, he let the "second cup half price" event slogan be hung for a whole month... You see, not setting subtitles can really delay business!

1. 3 things you must understand before setting subtitles

1. ​​Hardware connection is the foundation​
   Just like a mobile phone needs to be plugged in to charge, the LED screen must also be connected to the computer through a network cable, HDMI cable or a dedicated signal cable. Key reminder: Many new models now support wireless transmission, but novices recommend using wired connections first, which has higher stability.

2. ​​Check your own screen model​​
   Different models are like mobile phones of different brands, and the operating interfaces may vary greatly. It is recommended to look out the product manual and find a model code like "NS-P4" and "NS-TR86" to write it down. This directly affects subsequent software selection.

3. ​​Don't be careless about software installation​​
   Regular manufacturers will provide special control software (usually in the random USB drive or official website download area). Pay attention to two details when installing: ① Turn off the antivirus software to avoid interception by mistake ② Do not select the C drive on the installation path, otherwise the system update may lose data.

2. Teach you step by step to complete the setup

Let’s take the most common computer operation as an example, and follow the steps:

​Step 1: Start the control software​
Double-click the desktop program with a display icon (usually a red or blue logo). The device selection window may pop up when the first time you open it. At this time, you need to enter the screen model you recorded before.

​Step 2: Parameter setting to set the universe​
There are pits hidden here that 80% of novices will fall! In "Screen Settings" or "Parameter Configuration", you must fill in exactly:

• Screen size (If you choose pixels or centimeters in unit, please refer to the instruction manual)
• Point spacing (such as parameters such as P2.5/P3)
• Scan method (1/16 scan or static scan)

​Step 3: Text arrangement is of particular importance​
When entering promotional phrases such as "Second Cup Half Price" in the editing area, please note:

• The bigger the font size, the better. It is recommended to have characters ≥40 on the outdoor screen
• Red background with white characters is more eye-catching than yellow characters
• Remember to type in multiple lines of text, don't squeeze into a bunch

​Step 4: Select the dynamic effect well​
There are generally these options in the software:

• Scroll left and right: suitable for long paragraphs of text
• Floating and falling: suitable for short promotional words
• Type verbatim: Suitable for important notifications
  Don't choose "random effects" to read the cool effect

​Step 5: Do 3 checks before sending​​
Before clicking the send button, be sure to confirm:

1. Is the screen power and signal light always on?
2. Is the computer and the screen on the same network (when connected wirelessly)
3. Is there any mosaic or afterimage in the preview window

3. Emergency Guidelines

Novice are most afraid of encountering "no display after setting up". Here are some teachings for you to quickly troubleshoot:

​​Status 1: The sending is successful but the screen is black​
→ Check if the power plug is loose
→ Confirm whether the screen standby mode is turned off
→ Re-plug and unplug the signal cable (remember to turn off the power supply first!)

​​Status 2: Incomplete text display​
→ Return to parameter setting to check screen size
→ Check if the text is outside the edit box
→ Try changing the font from "Microsoft Ya Black" to "Bold"

​​Status 3: Severe color deviation​
→ Restore factory settings in "Color Correction"
→ Check whether the signal cable is used as a VGA cable (HDMI recommended)
→ Contact technical support for remote debugging

4. Advanced skills that experts use

After mastering the basics, you can try these operations to improve the effect:

• ​Time-dividing display​: Set the "breakfast package" in the morning and the "buy one get one free" in the afternoon to automatically switch
• ​Multilingual switching​: The tourist area stores can be broadcast in four languages ​​in Chinese, English, Japanese and Korean
• ​Remote control​: You can change the promotional information by using your mobile phone when you are on a business trip (the IoT function needs to be activated)

Editor's opinion: In fact, setting subtitles is similar to learning to use a smartphone. At the beginning, it looks complicated, and after you figure out the trick, you will find that it is nothing more than three core actions: connecting devices, inputting text, and sending content. The key is to overcome the fear of difficulties and get started with practical exercises a few more times. If you really encounter problems that cannot be solved, remember that the manufacturer's technical hotline is much more useful than Baidu!
