Captured Resolution Doesn't Take Value Entered

I used Custom for the size (3840 x 2160), yet the final render is only 1345 x 860.

The output picture looks good, but the dimensions are off.

I also tried using the Rendered product that also has 3840 x 2160 (view port settings), and this was the same result.

Thanks

Hello @DataJuggler! I informed the development team about this issue. I will post back when I have more information.
