4K on HD Monitor with UltraStudio Mini Monitor

Hi,

i have 2,8K Material in 4:3 and made my "Timeline Format" under "Master Project Settings" equivalent.
The Problem is that my HD Monitor which is connected with the UltraStudio Mini Monitor only shows part of the image. If i change the "Timeline Format" to HD it works fine but i want to work with a Timeline which is equivalent to my Material... What can i do?

Best, David

In the Image Scaling preference tab, change the output scaling preset to HD.

Great thank you!
