hdmi to vga cable, video issue with dim output

When installing this cable on an OptiPlex 390 with HDMI output to a Dell monitor with VGA input, the video is very dim and darker than the my second monitor (dual monitor configuration). The reason for purchasing this cable was to have dual monitors. The monitors are the same type and model. One is connected VGA to VGA, the second is connected HDMI to VGA via this cable. Any reason why it should not work as expected?

Hi Bill,

Thanks for contacting us! We’re sorry to hear that you’re experiencing issues with your HDMI-VGA cable.

Is your other VGA monitor available to test with the HDMI-VGA cable? We’d like to see if the behavior changes with a different monitor if possible.

Is your OptiPlex 3010 desktop system using the latest graphics drivers? If not, that may be the cause.

Please feel free to contact us directly at support@plugable.com if you need further assistance.

Thank You,
