System: Ubuntu-Mate 20.04, ;Samsung 40” TV, native resolution 3840 x 2160 HDMI 2.0; GTX 1060, HDMI 2.0; cable “high speed”.
Ubuntu will not display 2560 x 1600 or 2560 x 1440 pixels on my TV monitor with Nvidia “nvidia-driver 525-distro non-free recommended” installed. Software & Updates show this to be the correct driver to install. I need to be able to switch between resolutions 3840 x 2160 and 2560 x 1600.
xrandr shows the resolutions are not available. some other diagnostics:

When I boot to Win10 or Win7 on the same PC, the 2560 x 1600 or 2560 x 1440 resolutions are available.
Is there a way to get Linux to display the resolutions?
