It was working well on Win 10 Version before 1709, and the problem arose straight after the update to V1709. The driver is 8.970.100.9001 dated 13/1/2015. I've tried "Update Driver", but Windows reports the best driver is installed.

The reboot after reset resulted in 1770x1000, which is an underscan. Trying something else, using CRU to insert 1780x1010 and running CRU reset results in "Invalid Format". Rebooting takes the setting back to 1920x1080 or 1770x1000 (it varies). Selecting 1780x1010 in PC Settings/Display results in Invalid Format.

It looks like Version 1709 is responding differently to CRU.

It's more like the driver doesn't fully support the latest version of Windows 10. That card is too old and not even officially supported in Windows 10 by AMD, so the available driver might not have all the functions. The driver that Windows installs doesn't even have the control panel, so you can't control things like underscan. You really need a new video card, at least 7000-series or newer for the latest version of Windows 10.
