What should I do?anyone know?

What should I do?anyone know?

Edit: Found it, you just have to do:

e.g. DK2 (8:9 aspect ratio)
HighResShot 960x1080

you can ever render at 4k resolution e.g.
HighResShot 1920x2160

And you will get the proper screenshot saved.

To have your preview in the same format issue console command ‘hmd mirror mode 2

and change your preview window resolution

Oh,Thank you very much!
Have a nice day!
