XH90: how is 120 Hz going to work on a 100 Hz panel?
Hallo, I got XH9077 connected via HDMI 2.0b to GeForce 1080Ti.
Im pretty happy with the image quality and the software, but I got a question regarding the 120 Hz feature.



According to Sony press release (https://presscentre.sony.de/pressreleases/der-neue-4k-hdr-full-array-led-fernseher-xh90-von-sony-ist...) it got a 100 Hz panel:

- Einzigartige Bewegungsschärfe und flüssige Bilder mit X-Motion Clarity Technologie und 100 Hz nativem Panel selbst in schnellen und actionreichen Szenen



According to Sony Technical Specifications (https://www.sony.de/electronics/fernseher/xh90-series/specifications😞



4K120 support through firmware update.



HDMI™ Signal: 4.096 x 2.160p (24, 50, 60 Hz - where are 120Hz ??? <--), 3.840 x 2.160p (24, 25, 30, 50, 60 Hz), 1.080p (30, 50, 60, 100, 120 Hz), 1.080/24p, 1.080i (50, 60 Hz), 720p (30, 50, 60 Hz), 720/24p, 576p, 480p



I don't get it. The TV is advertised with 4K120 (via update), but specifies 4K HDMI Signal max 60Hz only, uses a 100 Hz panel... How is it going to work, once true HDMI 2.1 GPUs become available? If GPU sends 4K@120Hz, how is Bravia going to display that on a 100 Hz Panel? Will it just trow random frames away? Will it interpolate and introduce additional >10ms lag required for the interpolation?
