hello muttu2704,

may I know what’s your 120Hz frame-rate use-case, is it display or sensor outputting?

if you’re working with 1920x1080@120-fps sensor, could you please share more details. thanks
(1) could you please share which sensor driver you’re working with.
(2) following by (1), please verify that signaling outputting is correct

hello JerryChang,

Yes, it is for display outputting from HDMI of Jetson TX1.

Our Xorg driver would not allow user to define their own mode. All modes are available only when EDID from your monitor has it on list.

hello WayneWWW,

I connect board to HDMI input of TV, and TV supports 1920x1080 @120Hz.
In this condition, if run:
$ xrandr

120Hz is not listed.

TX1 does not support such frame rate. Currently, I guess it is just up to 60fps.

Okay, Thanks WayneWWW for the info.
