[Vasiliynap]

Hello ! Can somebody help me please ! I got a new Sony a6400 and I bought it for video. Im trying to get grid lines in video mode but it showing me that it is not available in video mode. I have a grid lines in Manual mode but can't get them in video. In settings grid line option is grey color and it is off and when im trying to change it it showing that grid lines operation not available as follows video mode. Is anybody had that before ?

I owned a 6300 for a while and if I remember the grid line would not show if I had the level turned on

I may be late, but... I looked for this as well and found that if you turn off the marker display, it automatically turns on grid lines in video mode, that's if you had it on in other modes.

Menu> page 2> Tab 3> Marker Display.
