Check the AMD/ATI Radeon settings application in Start Menu>>all apps
Or right click desktop and the display setting for Radeon might be in the context menu.
What are the 3 resolution settings it gives you.
Have you tried to adjust the Bravia TV settings on the TV ???
Have you went to settings>>System>>Display>>advanced display settings>>display adapter properties for this TV monitor>>Monitor tab
and changed the refresh rates for the TV Monitor. or uninstall the TV drivers and update them or roll them back.
you need to restart PC after changes.
Is this a PC and only 1 monitor HDMI from Video card to TV.
I would go here and enter your card specs and download the drivers/software for it for Windows 10 if they have 10 drivers. If not, you are stuck with Microsoft generic display drivers.

There is no drivers for windows 10 on their website.
Windows 8 is the last
Display Driver ver. 8.97.100.7
OpenCL(tm) Driver 10.0.937.2
Catalyst Control Center 2012.1116.1514.27190
So you show your driver as
15.201.1151.1008
I have Radeon HD 4600 series crossfireX Windows 10 pro v1803
driver installed is
Advanced Micro Devices, Inc.
8.970.100.9001
with 3 monitors connected
No Catalyst control installed.
Never any issues.
I think you have the wrong drivers.
I would download the Windows 8 64bit, uninstall your drivers and CCC
restart pc and try to install the Windows 8 version.
Obviously mine is running on the windows 8 version.
But I do not have CCC installed.
