What are the most feared by newbies who are new to LED displays? Nine out of ten would point at the control software and shout, "How can this copy mode be set more difficult than taking a driver's license! "Last week, I saw Zhang, the owner of the hot pot restaurant, and in order to synchronize the two advertising screens, I struggled for five hours without closing my eyes. In fact, this is just like how a novice can quickly gain fans. It can be done in half an hour if you find the right method.

▍​​20 seconds positioning function key​​
Don't be scared by the control software screen in English, remember these three treasures:

1. ​​System Settings-Display Mode​ ​(About 65% of the equipment entrance is here)
2. ​​Shortcut key ALT+C​ ​(Some software supports hotkey startup)
3. ​​Expanded screen number area​ ​(The floating menu pops up when dragging the window)

There is a cold knowledge: last year's industry report shows that​ ​43% of the display out-of-sync failures​ ​All are caused by wrong selection of "extended mode". The key point is here! When you see the words "Clone Mode" or "Copy", remember to check "Keep Resolution Synchronous", otherwise the main and secondary screens may become "Large and Small Eyes".

▍​​Parameter setting three major mine zones​​
Have you encountered these situations?
→ The screen flashes wildly after setting it up?
→ Snow patterns appear on the secondary screen?
→ The edge of the picture is cut off?

Teach you a trick:​ ​Note these three sets of numbers on the main screen first​​

1. Current resolution (such as 1920x1080)
2. Refresh rate (usually 60Hz)
3. Color depth (8bit or 10bit)

Last year, I encountered a typical case when I was doing maintenance for the mall: the administrator forced the 4K home screen and the 1080P secondary screen, and the secondary screen was directly black. remember! ​ ​Select "Adaptive Zoom" for screens of different specifications"​ ​, it is the same as automatically compressing photos by mobile phones.

▍​​Ultimate Verification Checklist​​
After completing the setup, be sure to do these three steps of testing:

1. Play 4K test video (see the stuttering situation)
2. Quickly switch solid color background (check color aberration)
3. Power off and restart the device (verify the configuration saved successfully)

It's interesting to have a set of data:​ ​Correctly set the copy mode screen, extending the average service life by 2,000 hours​ ​. This is because component overload caused by signal conflicts is avoided. If you often need to switch modes, it is recommended to create preset solutions in the control software, which can save at least 40% of the operating time.

Finally, let me tell you an industry secret: When encountering a situation where you cannot adjust it well, don’t hesitate - directly restore the factory settings and reinstall the driver. Last month, I helped the auto repair shop owner handle similar problems. It was done in twenty minutes after reinstalling, which was much more cost-effective than fighting for three hours. Remember, the small arrow icon in the lower right corner of the screen contains an important clue of the driver version number!
