Duplicate screen option not working

[0jimbo]

Thank you for your reply, Albon.

I don't think your concern that I might not have the
primary graphics card driver (Intel/Nvidia/AMD) which supports cloning across graphics adapters is warranted. Before my HDMI port stopped working, I was able to easily clone my PC with the monitor so I believe the driver is probably there.

I bought your device as a USB work-around. Considering that I probably do have the correct graphic card driver, do you have any other suggestion?

Thanks,
