We've also updated the 1440p 60Hz input lag with this latest firmware. We don't know why our previous measurements were higher, as we did confirm them twice. Update : We've retested the input lag on the same firmware (03.50.31) and found the 4k 60Hz + HDR input lag is in the same ballpark as the other resolutions (around 13ms). The input lag measurements in SDR game and PC modes have decreased. Update : We've retested the input lag of the LG C9 with the firmware update 03.50.31. These measurements were taken in the 'Expert (Dark Room)' Picture Mode, with OLED Light set to '100', Contrast set to '90', Peak Brightness on 'High'. Unlike most TVs, the C9's peak brightness was measured with the pre-calibration settings, due to an oddity with the 100% window. If ABL bothers you, setting the contrast to '80' and setting Peak Brightness to 'Off' essentially disables ABL, but the peak brightness is quite a bit lower (246-258 cd/m² in all scenes). Increasing this setting to 'Low', 'Med', or 'High' increases the peak brightness of small highlights. Setting this to 'Off' results in most scenes being displayed at around 303 cd/m², unless the entire screen is bright, in which case the luminosity drops to around 139 cd/m². The LG C9 has a new Peak Brightness setting, which adjusts how the ABL performs. Small highlights are brighter than on the C8 or B8, but this results in a more aggressive Automatic Brightness Limiter (ABL), which dims the screen significantly when larger areas of the screen get bright.

The LG C9 OLED has good peak brightness with SDR content.

There are no significant changes in brightness from our previous measurements. Update : We've retested the SDR peak brightness of the LG C9 with the firmware update 03.60.02.
