According to Samsung website the support for Windows® 10 is limited; there are no drivers available so it is necessary to use generic drivers provided with OS.
Let’s try to narrow down the issue. Unplug the second TV (monitor) from your computer, uninstall and delete the current graphics driver and Audio driver.
Then, restart the computer and run Windows® 10 update. Test your second monitor.
Let me know how it goes.
