Improvements and bug fixes for your graphics card should eventually filter down from the latest kernels into the stable kernel series, and from then into Ubuntu. If you want to make sure of that, you can file an upstream bug report at bugzilla.kernel.org

I'm pretty sure the Monitor's resolution was properly detected in 15.10 (4096x2160). It was called "Goldstar Company Ltd" but I do not recall which size was detected. (27" or 31") I remember seeing a 4K youtube video in 15.10 and noting the black bands on each side of the display, due to the difference between 3840 and 4096. --- ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None CurrentDesktop: XFCE DistUpgraded: 2016-04-14 20:11:08,467 ERROR got error from PostInstallScript ./xorg_fix_proprietary.py (g-exec-error-quark: Failed to execute child process "./xorg_fix_proprietary.py" (No such file or directory) (8)) DistroCodename: xenial DistroRelease: Ubuntu 16.04 DistroVariant: ubuntu ExtraDebuggingInterest: Yes GraphicsCard: Advanced Micro Devices, Inc.
