CPU: Ryzen 5 2400 G
MOB: Gigabyte GA-AB 350 N-Gaming WIFI (BIOS F22b)
OS: Win10Pro x64
With the above configuration, driver installation and display in which the screen is divided into three (the screen is divided at the center, half is duplicated display, and the right half is duplicated and displayed on the upper and lower sides respectively), the mouse cursor moves to the right half area When it reaches the monitor darkens to blue or green one color.
Reinstallation of driver, clean installation of OS, change of BIOS, graphic driver posted on Gigabyte site, try any one will not improve.
Since abnormality can not be confirmed especially when displaying with the POST screen or Windows standard driver, it seems there is a possibility that the driver has some problem.
I'm waiting for distribution of modified drivers as soon as possible!
