Why the Upper Screen not showing anything?Updated 6 months ago
Most upper screen not display issues are typically due to driver installation problems. Please follow the steps below to troubleshoot, which should take approximately 5-10 minutes. Thank you for your patience and time.
For Windows user:
1. Check if the driver is running properly
- Check in the task manager if the process "Macrosilicon USB Display" is functioning as below. If you can't find it, means driver install fail, kindly refer to driver installing again.
- If it has been installed correctly, please manually find and start it in the system program list. For the problem of driver self-starting, please refer to the solution to the problem of "Windows system driver does not start automatically".
2. Check whether the driver is loaded successfully
If you see below symbol on the driver in Device Manager, means it's not loaded successfully and need a update:
Follow below steps:
- Right-click (or long press) USB Video;
- Select "Update Driver";
- Choose manual update and select the driver in Delta. The default installation path is "C:\Program Files\Win USB Display"
- The following pops up means the installation is successful.
3. Check if virtual graphics card MS Idd Device exists
Confirm whether the MS Idd Device virtual graphics card exists in the device manager. For the correct status, refer to the figure below:
For MacOS user:
Versions after MacOS 10.15 require users to authorize the "Screen Recording" permission in order for the corresponding device to obtain the screen content. To enable Screen Recording, follow these steps:
- Open System Preferences from the Apple menu;
- Select Security and Privacy;
- Select the Privacy tab;
- Click Lock to make changes;
- Follow the prompts to enter the password and allow changes;
- Click the checkbox next to MacUsbDisplay
- Click Lock again to save changes;
- Click Exit now
If there is still no output after turning on the recording permission, and you are still prompted to turn on the screen recording permission after restarting, please first remove the program recording permission that contains the word "usbdisplay", then restart the system and add it again.
When using HDMI connection
In some case when connect Delta by HDMI cable, a USB-A to USB-C cable is also needed to connect your laptop to the upper screen
When using DP to USB-C cable
