Unity automatically scale my picture resolution down and resize it back to normal?

I’m trying to create pixel art style images
I have a .psd file sized 38403840px
but when I go back to unity screen and select the psd from the project window
it shows that the file is 2048
2048px in the preview window.
I drag it to the scene window and the edges of the picture looks blurry
I have another .psd file having only 19201080px and I did the same to put it to the scene and have no issue with the resolution.
I’m wondering why unity reduces the .psd resolution. Is there a max limit for the size? (if there’s one then I assume it is 2048
2048?)

please see my screenshot

hope someone know what goes wrong… Thanks !!

If I’m not mistaken, you can check the import settings and at the bottom, in the inspector, you’ll see “Max Size” You can adjust that… the max is 4096x4096 I believe.

4096 will work, provided your graphics card or target hardware supports it.
