NVIDIA Quadro SDI sync detect incorrect
I have a FX5800 with a Quadro SDI board next to it. When the SDI board is fed 1920x1080 23.98 PSF sync it detects it as 1920x1080i 47.96HZ (SMPTE274) which is incorrect. I have tried drivers: NVIDIA-Linux-x86_64-190.42 NVIDIA-Linux-x86_64-190.53 and NVIDIA-Linux-x86_64-256.53. All show the wrong sync type. The firmware version on the SDI board is 3.09.
If the SDI board is fed 1920x1080 23.98P or 1920x1080 59.94I it detects them as the correct type.
All this info came from the NVIDIA X Server Settings.
Is this a bug? Is there new firmware for the SDI board?
