Thank you for reaching out to BenQ Support. We sincerely apologize for the inconvenience you are experiencing with your GV32 when using it with the Nintendo Switch.
Our engineers have identified a technical issue related to the USB-C processing IC, which is affecting the signal with DP-alt mode display communication, and will result in no signal issue when used with the Nintendo Switch.
We understand how frustrating this can be, and we are sincerely sorry.
We have released a fix for this particular issue.
You can now download the firmware update tool from our website.
