Alas, have you ever been worried when you stared at the green faces on the LED screen? Last week, Lao Wang took on a job in the mall. As the big screen was broadcast, the screen was suddenly filled with mosaics - guess what? The brightness parameters are not adjusted correctly! Today, let’s talk about this problem that makes people bald, so that you can avoid 80% of the pitfalls after reading it.

1. Are the parameters hidden more hidden than the year-end bonus?

​​The control card is the real big shot​ ​, This thing usually hides in three places:

• In the steel frame base of the outdoor screen (the rainproof cover must be lifted)
• The frame mezzanine of the indoor screen (find the frame and look for the raised button)
• Splicing gap of floor tile screen (magnetic suction snaps can be opened as soon as you break it)

Last year, a large screen strikes in a exhibition, and 20 people circled around the screen to look for the control card. Finally, I found it hidden in the dark lattice on the stage floor. You said that this design is like hide and seek! Nowadays, professional installations will paste fluorescent stickers at the control card position, and you can find them at a glance even if you are in a dark light.

2. The brightness parameters are not adjusted well = burn money

The brightness difference between indoor and outdoor is 100,800 miles away! Remember this​ ​Golden formula​​：

• Indoor: 800-1200 nits (just as bright as the mobile phone screen)
• Showcase: 1500-2000 nits (must be overwhelmed with natural light)
• Outdoor: On sunny days, you have to soar to 5,000 nits to see

A lesson learned from a bloody and tears: a chain supermarket has adjusted the brightness of the indoor screen to 2,000 nits, and burned the power module in three months, and the maintenance fee is enough to buy ten new screens. Now those who know how to match​ ​Light sensor probe​ ​, let the screen change with the light and dark environment by itself, which is much more worry-free than manual adjustment.

3. If the refresh rate is not adjusted correctly, your eyes will suffer

1920Hz is the industry threshold, but the specific scenarios must be flexible and flexible:

• The conference room is enough to adjust to 1920Hz (power saving and eye protection)
• The e-sports venue must start at 3840Hz (or the high-speed screen will be full of shadows)
• Film and television shoots must be 7680Hz (8K cameras are not vegetarians)

The most exaggerated case I have ever seen: A live broadcast base uses a screen shot of clothes with a low refresh rate, and the audience in the live broadcast room said they were dizzy and wanted to vomit when they looked! The return rate dropped by 15% on the day after adjusting the parameters. Do you think the good parameter is adjusted directly related to the thickness of the wallet?

4. Color temperature calibration is a metaphysics

Remember these three​ ​Life-saving value​​：

• 6500K for shopping mall promotion (cold white light shows lively)
• Jewelry counter is 3000K (warm yellow light is luxurious)
• The middle value of the conference room is 5000K (close to natural light)

A gold shop suffered a secret loss - using cold white light to make gold jewelry, but the customer said it looked like a gold plated! Later it was adjusted to Warm Light, and sales rose by 30% that month. Now all high-end control systems have​ ​Scene memory function​ ​, switch different color temperatures in the morning, noon and evening with one click.

5. Advanced gameplay: HDR dynamic adjustment

This function is like installing a smart brain on the screen:

1. Automatically identify the light and dark areas of the screen
2. Adjust the Gamma value for each block separately
3. Real-time balance overall contrast

After the HDR is turned on in a 4S store, the texture of the black car paint is directly improved by two levels, and the customer stays for 7 minutes more. However, this function takes hardware, so you have to confirm that the control cassette can only be played with the independent image processor.

If I ask, adjusting parameters is the same as adding salt to stir-frying dishes - the more the better, it depends on the ingredients. Next time you encounter a screen snoring, don’t rush to curse, maybe you can revive the dead by moving the parameters. Remember, the good screen is a good one. If you practice this technique, it will be much more effective than changing the equipment!
