[DaneLLL]

Hi,
Please refer to the topic:

Nvvideoconvert issue, nvvideoconvert in DS4 is better than Ds5?

Hi, Please excute the steps to run VIC in max clock and try again: Disable runtime suspend of VIC $ echo on > /sys/devices/13e10000.host1x/15340000.vic/power/control Set userspace governor $ echo userspace > /sys/devices/13e10000.host1x/15340000.vic/devfreq/15340000.vic/governor Set max_freq $ cat /sys/devices/13e10000.host1x/15340000.vic/devfreq/15340000.vic/available_frequencies $ echo [max_freq_val] > /sys/devices/13e10000.host1x/15340000.vic/devfreq/15340000.vic/max_freq Set targ…

to run VIC at max clock and check again.
