Gigabyte has released a trio of AORUS gaming monitors, the AORUS FI32U, AORUS FV43U and the AORUS FO48U. All are 4K monitors with HDMI 2.1 ports, but only the flagship 48-inch model has an OLED panel. The three monitors should deliver excellent colour accuracy though, and can output at up to 144 Hz in most cases.
