{{ImportantMessage|text=As described on the table above, not all OPPs can be used with video output enabled. In fact OPP0 has does not have enough processing power on HDVPSS to display even static images on HDMI (VOUT1) @1080p60. For streaming video processing (e.geg. H264 decoding) at least an OPP100 or higher is required.}}
{{Board Specific Information|text=Please note that A8 settings can be overloaded by Linux Kernel governor (see previous section). Choose ''userspace'' governor to configure A8 performance with static OPP.}}
OPP settings can be changed globally (in other words: the same OPP for each subsystem) or locally individually (a different OPP for each subsystem).
OPP setup can be done performed via sysfs interface. For example to globally configure ''OPP50'' globally , enter the following command at [[:Category:Naon|Naon]] console
