How to fix the lagging problem of your wireless display adapter?

The fundamental reason why wireless presentation systems can be popular in conference rooms, and multimedia classrooms is that the lagging of wireless casting screens is significantly reduced and the speed of wireless transmission has been improved. Screen mirroring can meet the needs of normal meeting presentations. However, in the application of wireless display, many people still find that the delay is very serious, so how do you solve the problem?

What leads to the lagging?

Actually, wireless screen mirroring requires the participation of two important objects, one is the casting screen transmitting source (cell phone, computer, casting screen transmitter, etc.), and the other is the casting screen receiver (TV, LED screen, etc.).

The misconception of many people

Many people believe that the delay in screen mirroring is caused by network speed. It seems that this is an inescapable reality, but the truth is that when it comes to professional screen casters, this oft-repeated claim really isn’t true.


The typical DLNA, Miracast, or Airplay wireless screencasting methods do not experience any type of slowdown – whether 100 megabits or gigabits – from the data traveling across a LAN. In other words, the only thing that matters when it comes to the fidelity and accuracy of your streaming experience is your router’s total bandwidth.

Simply put, if you upgraded from a 100-megabit router to a gigabit router, you’ll notice virtually no difference in latency between either device. This means that regardless of your connection speed, as long as you have enough bandwidth to handle large files and multiple streams at once then you’re all set!

So next time someone tells you that they don’t know why they’re experiencing lag while casting their screens – just remember what professional screen casters know best: a strong connection won’t necessarily be slowed down by dubious claims like those of many people without firsthand experience.

In the case of DLAN screen mirroring: The network bandwidth directly leads to the DLNA screen mirroring latency

DLNA push casting is rapidly becoming the preferred method of watching films and TV shows as it allows viewers to watch their favorite content on a larger screen. The process is relatively straightforward – just select the program you want to watch on your phone or laptop, send the URL link of that show or movie to the receiving end such as TV, streaming box, or streaming software, and let them do the work.

In this process, your device functions in a similar way to a remote control; all you need to do is “push” the desired program and let play it. With DLNA push casting, you don’t have to worry about technical lags or glitches appearing while watching your favorite content – a common problem with traditional wireless screen casting.

To ensure a seamless viewing experience free of any delays, double-check that the link you’re pushing has been received by the receiving end properly before pressing play.


After understanding the above principle, the solution to the delay of the DLAN wireless display is also very simple. That is to ensure the bandwidth of the network!

In the case of miracast and Airplay mirroring

1、Optimize the sending side to improve the coding performance. Many people rely on their smartphones and other devices for essential everyday tasks such as scheduling, entertainment, and communication.

However, having a device is only part of the equation – it also needs to perform at an optimal level in order to be truly useful. When we run our phones, tablets, and computers with cast screens open, we expect smooth performance without any lag or delays.

So choosing the right product can make all the difference between a problem-free experience and one full of headaches. That means if you want better experience when mirroring your screen, you’d better have a better tablet or smartphone. That doesn’t mean you have to buy an iPhone or iPad, but as long as the device itself runs smoothly.

2. If you have enough budget, you can consider a professional wireless presentation system. Home screen casting boxes usually cost tens of dollars, while professional wireless screen casters maybe start from thousand dollars, or even over ten thousand. The price of high-performance chips is geometrically increased.

For the moment, the vast majority of conference rooms, and multimedia classroom users feel that the screencast lag and the simple reason is that, they just want to use some household device to achieve professional screencasting work, which is quite nonsense.
