Question about Sony KD-55X75WL

Hi maurus.neff,

the frame rate is 50/60 Hz. However, there are 2 HDMI sockets that support 120 Hz. If you are using an HDMI device that supports 8K or 4K 100/120 Hz video output, connect the Ultra High-Speed HDMI™ cable and follow the on-screen instructions to set the [HDMI Signal Format] of the HDMI IN connector. If you are using an HDMI device that supports 4K 100/120 Hz video output, connect the Ultra High-Speed HDMI™ cable and follow the on-screen instructions to set the [HDMI Signal Format] of the HDMI IN connector. Please note that 4K 100 Hz support depends on your country/region .

I don't see 120hz anywhere in the settings on mine.
I would refer to the manufacturer's specifications. If it had 120hz, they would surely advertise it...

I have 120. But I don't have any games that run at 120, so I haven't tested it.
