We've retested the HDR brightness and HDR Brightness in Game Mode with the latest firmware (version PKG6.0414.0055NAA). Verified VRR support, but it still doesn't work. We also added new local dimming videos that use real content. We retested the HDR Peak Brightness with Local Dimming on Medium. We also reconfirmed that the blur issue is still there, and did a side-by-side comparison with the Sony X950H. We updated the Sony X900H to the latest firmware, PKG6.0466.0059NAA, and retested contrast, local dimming, peak brightness, and the color gamut. Updated the firmware to PKG6.1288.0155NAA and confirmed it now supports VRR. We retested the input lag without VRR with the latest firmware. We retested the VRR feature, input lag, and peak brightness in the new 'Enhanced format (VRR)' mode. We checked the variable refresh rate feature with the latest firmware, v6.1534, and retested the peak brightness. We changed the 'PS5, Variable Refresh Rate' result, as the TV now supports VRR. We tried to reproduce a stutter issue that some users report was introduced in the Android 10 firmware update. Retested the VRR support after the latest firmware update. The text has been updated in the 24p Judder section. We've confirmed that the TV skips a frame every 42 seconds while watching movies from an external source.

Clarified that you can't enable VRR with local dimming.
