USB Screen Needs and Data Throughput
Unlike normal computer screens which use HDMI or DP connections USB screens like the VoCore and USBD480, as featured in GSI wheels, necessitate a consistent and uninterrupted flow of USB data and power for optimal performance.
When there's a compromise in data throughput, it can lead to undesirable effects such as screen "tearing" or "flickering," depending on the screen model.
The image displayed below serves as a common example of a VoCore screen experiencing reduced data throughput or interruptions, resulting in compromised output referred to as "tearing."
To address this concern effectively, consider the following straightforward measures:
Avoid USB Extension Cords: Refrain from using USB extension cords, as they can lead to both data and power degradation.
Should an extension be necessary, consider opting for a powered USB hub.
Lower LED brightness on wheel to draw less power, this can help Vocore screens not to tear/flip

Utilize a Powered USB Hub: Especially on systems utilizing AMD technology, known for relatively weaker USB performance, employing a powered USB hub can be immensely beneficial.
Distribute USB Load: Prevent overloading a single USB channel. These channels distribute data uniformly across connected devices.
For instance, you might allocate a dedicated powered USB hub solely for sim equipment,
while other peripherals remain connected to the motherboard's USB channel.
In cases where your screen encounters interruptions, a simple reset can be achieved by unplugging and then re-plugging your wheel. To prevent such situations in the future, adhere to the aforementioned guidelines.
For USBD480 screens, reducing the frames per second (FPS) to 20 can significantly lower data requirements and mitigate flickering issues.
Another effective approach involves decreasing screen brightness, which subsequently reduces power consumption, yielding favorable outcomes.
By implementing these strategies, you can ensure a seamless and optimal experience with your USB screens, enhancing both data integrity and visual output quality.
