4K vertical is not filled

My clip was taken from Iphone with 4K 60 in vertical. I set the timelime setting to 2160x3840 when I drop the clip it does not fill the full screen. It show black on conner. Then I use inspector>>transform to scale up the video to fit the screen but the video is still remain the same ratio and the only change is the image inside. It does not scale to fill the screen. I have already zoom the clip to be biger than the screen as you can see form indicator but it doesn't fill the black.

That's awkward. Let me ask first: do you have Resolve Studio? otherwise vertical limit is 2160 I think. You also might want to check your Image Scaling settings in the project settings or on the clip properties itself if you wish to change it only for that clip. Maybe it needs to be set to center crop, no resize.

I am using free version, yes I think the limitation is 2160.

Thanks for flagging this
