Customer Reviews for StarTech SV431DPUA 4 Port USB Dual Link DVI KVM Switch with Audio

Thank you for your feedback Julien. We understand your disappointment in the performance of our SV431DPUA and we'd like to help troubleshoot this issue. We have a FAQ available regarding the disconnection of displays when using DisplayPort KVM switches here: http://www.startech.com/faq/Windows_Resize_KVM_Switch#SV431DPUA. This FAQ is referencing behavior in Windows but if the Ubuntu computer has difficulties when there isn't a display connected this could be what's causing the problem you're seeing. One fix, as recommended in the FAQ, is using a DisplayPort EDID emulator, of which both software and hardware versions are available. If you have any questions or require any assistance, please feel free to contact us at www.startech.com/support. Our Technical Advisors are available 24 hours a day, 5 days a week to provide support.

Thanks for leaving your feedback on our SV431DPUA KVM switch. We're sorry it didn't work well and would like to offer some help. Some 4K DisplayPort monitors can be problematic with extenders or KVM switches between them and the computer. We'd like to look into this further, please contact us by phone or live chat and mention this review.

We're sorry to hear about the problems you've had with SV431DPUA. It sounds as if your computer is losing the EDID information of the display when you switch away from it. In order to fix this, we suggest updating your graphics drivers, and if possible, removing any video adapters/converter cables between your computer and SV431DPUA. If you continue to have any problems, we recommend contacting our Technical Advisors at www.startech.com/support. We're available 24 hours a day, 5 days a week, to provide support.
