The screen was connected using the USB-C port of the laptop show "No Signal"?

It means that your laptop's interface is just a USB-C port and not a full-featured Type-C port, which results in the inability to output video. In this case, you will need to purchase accessory H5 video cable to help with the conversion and achieve the video output effect.

The screen was connected using the USB-A and HDMI port of the laptop show "No Signal"?

It appears that the connection port for your screen is incorrectly connected, for example, connecting the HDMI cable from your laptop to the screen's Type-C port, which results in no video output to the screen.Please pay attention to the instructions located at the connection port position on the screen.

Macbook only one screen work?

For Mac OS systems, Macs equipped with M1/M2/M3 chips such as MacBook Air 2020/2022/2023/2024 or MacBook Pro 2020/2022 can only connect to one external display, and you can use the H5 video conversion cable we developed to connect the screen. These MacBook models only have 2 USB-C ports, and the 2 external screens connected to the S2 product will occupy the charging port. It is recommended to purchase a USB hub with more than 3 ports and connect one of the screens using the 2 cables of the H5-T . Your MacBook can also be charged using the port on the hub. The other screen is directly connected to the USB-C port on the MacBook.
If you don't want to buy a USB hub, you can also connect the power cable directly to the screen. Our screen supports reverse powering the MacBook. The port connecting the screen occupies your laptop charging port,one screen wtih laptop USB-C (Power Delivery),Connect another USB-C to USB-C to this screen, and connect the other end of the cable to an external power source (just like charging a mobile phone). In this way, the screen is connected to an external power source, and this power source can also reversely charge the laptop.

The screen suddenly goes black and the display is unstable during use?

This often happens when the power supply is insufficient, because using multiple screens requires a large amount of power. If your laptop is low on power, this will happen. It is recommended to plug in the power cord for your laptop during work to ensure stable use for a long time.
