Hi,
Thanks for reaching out to us about this problem and we’re happy to help. First, since it sounds like the HP monitor works correctly I’d like to verify what types of cables you’re using to connect your Lenovo monitor or if you’re using any adapters to connect the monitor. Some adapters may not work so I’d like to verify how the monitor is connected first to check for any issues
Can you please let us know how the monitor is connected and what the model number of the ThinkVision monitor is so we can check those details?
I look forward to hearing back and helping with this issue.
Thanks!
