Hi Rudy-

Thanks for posting with your issue here!

This is typically an error we see when we ask a monitor to run at a resolution higher than what it is capable of.

As a 1st step, please try setting the resolution on the 2nd display to a lower value. Typically a modern “flat panel” or LCD/LED display will have a “native resolution” something like 1920x1080 or 1680x1050 listed on the box. The display will look best at it’s native resolution, although anything lower than it’s native will work, it just looks fuzzy or blurry.

Please let me know if this helps or if you have any further questions!

Thanks again for posting and please do let us know whether you find this helpful.

Best wishes-
