No video on Windows

Hello. I connected the Nreal air device on my Widows 10 Laptop with config below and the video does not work, just the sound works.
Intel Core i7-6500U 2.5GHz
NVIDIA GeForce 940MX with 2Gb Dedicated VRAM
8 Gb DD4 Memory
256 Gb SSD

The same device worked normally on another Windows 10 Laptop with config:
Intel 7 Gen Core i7-7700HQ
NVIDEA Geforce GTX 1060 6GB GDDR5
16Gb DDR4-2400MHz
256 GB SSD + 1TB HDD

For both application, I updated the firmware through Nreal Air - Activation and firmware update from both Chrome and Edge

Would you please help me?

Hi, please try to check if the USB driver and xHCI protocol version are different on these two PCs. Try to downgrade the driver version of the first PC.
