OK, 2.0 usb display - love it. Just one thing - driving my external monitor on kvm setup at 1600 x 900 and it does fine, except that the width is not filling the entire width of the monitor. I have black screen bars on both sides of the horizontal scan area. Is there a way to fix this from the driver?
Hello Tom,
Without knowing further details this sounds like an EDID (https://en.wikipedia.org/wiki/Extende…) problem. USB graphics in general will only display if an EDID signal is present and will only work with the resolutions provided by the EDID. Do you have the display adapter connected on the USB hub on the KVM switch? Are you mirroring or extending your desktop?
Kind regards,

the usb cable is in the pc directly, and the vga cable from the kvm is in the vga end of the adapter. there is a separate kvm usb cable for mouse and keyboard in a 2nd usb port on the laptop. Everything works fine, it just is not filling the screen. I believe the usb adapter and laptop correctly recognize the make of the monitor.
the setup is win 7 extended desktops, although there isn’t a reason I couldn’t mirror.
Hi Tom,
Thank you for clearing up with me. To verify the EDID theory, do you have the same issue if you connect the display adapter directly to the monitor?
Kind regards,

yes. Monitor directly to adapter, adapter in any of the three usb ports, the monitor is correctly identified but the scan issue remains the same.
Hello Tom,
I would need to take a closer look via PlugDebug. It allows us to get a better idea of which driver versions are on the system, as well as diagnostic and installation logs, while minimizing the amount of questions we send your way when we are looking into an issue.
Please head over to -> http://plugable.com/support/plugdebug. There you will find a download link as well as instructions. Please be sure to have the display adapter plugged into the computer with its monitor attached when running this tool and attach the resulting zip file in the reply to support@plugable.com. Once we have the .zip file it generates, we will get a better idea of how to best proceed.
Kind regards,

Hi Tom,
I was looking out for an email from you. Did you resolve the problem or do you still need assistance?
I believe I emailed it to support@pluggable.com. I realize now that even if received they weren’t aware of this thread. Is there a better way to get it to you?
