Do newbies who are new to LED displays often encounter such embarrassment - they want to take promotional photos, but the screen is full of black ripples? Or after debugging the parameters for a long time, I finally found that the key settings are just under my nose? Today we will uncover the mystery of the "controlled photo settings" that has driven countless people crazy!

1. Set three keys to the entrance

To be honest, finding this feature is like playing escape room. According to industry data, 83% of first-time users will get lost in these three places:

1. ​​Control software hide menu​: The icon that looks like a sandwich in the upper right corner of the main interface, clicking on it contains more than 20 advanced functions
2. ​​Receive card physical buttons​​: There is a small labeled SET button on the back of the box, and you have to poke it with a toothpick for 5 seconds to activate it
3. ​​Remote Control Mysterious Combination​​: Press and hold the "menu + confirm + power" buttons at the same time, and the engineer mode will jump out of

The worst thing is that the entrances of different models are different! But don't panic, remember this universal formula:​Follow the software three times, find the tags on the hardware, and test the key combination for five rounds​​。

2. Four Great King Kongs with Parameter Settings

After opening the settings interface, the full screen parameters are dazzling. Focus on four deadly options:

To give a real case: A shopping mall’s transparent screen promotional photo has rainbow patterns. Later, I found that the 3840Hz refresh rate was wrongly set to 1920Hz. After resetting it, it was immediately transparent like a glass window.

3. Three secrets for mobile phone shooting

Nowadays, there are more and more demands for using mobile phones to shoot LED screens. I will teach you three professional skills:

1. ​​Professional model must be opened​: Turn off the automatic exposure and manually adjust the shutter to less than 1/100th of the second
2. ​Focus Lock​: Long press the small sun icon that appears on the screen to avoid the brightness flickering
3. ​Use HDR with caution​: Although it can improve the details of the dark part, it is easy to cause highlight overexposure

A catering customer used this method to shoot the menu screen, and the number of likes posted on Moments doubled! Remember the formula:​Professional mode lays the foundation, focus locks to maintain brightness, HDR depends on the specific scene​​。

4. Those hidden skills that are abnormal

Some options in the settings interface seem irrelevant, but actually have a huge impact:

• ​​Blanking time​: Adjust this to eliminate the breathing light effect at the edge of the screen
• ​Color temperature synchronization​: Keep the display color temperature consistent with the on-site lights
• ​​Pre-shooting buffer​: When the continuous shooting is turned on, the screen is more coherent

The most awesome is​Adaptive shooting mode​, can automatically match parameters according to ambient light. A gymnasium in Tokyo used this function to take live photos comparable to professional cameras during the event.

5. Is it still not good to shoot after setting up? Check these three places

1. ​Network cable interface​: Don’t laugh! Sixty percent of the problems are that the network cable is not tightly plugged
2. ​Power supply phase​: The reverse connection of the three-phase electric device will cause the control card to burn (smell if there is any burnt smell)
3. ​​Grounding Resistor​: Many inexplicable ripples are poor grounding

There was an exhibition case last year. There were always snow spots on photos on large screens, and finally it was found that it was caused by static electricity on the carpet. Who would have thought of laying a copper foil grounding wire to solve it immediately?

After years of struggling in the industry, I have found that controlling the photo setting is like cooking - you must not only follow the recipe, but also know how to adapt to the situation. Newbie remember this mental method:​The parameters follow the scene, calibration cannot save steps, and the backup plan is available at any time​. If you really can’t handle it, don’t hold on. Isn’t the 24-hour technical support used at this time? After all, let’s leave professional matters to the professional team, and it is the best way to focus on creative presentation!
