64x64 RGB outdoor panel 2,5mm pitch

Hi,
are there any RGB outdoor panels with a small pitch of 2,5mm. I would like to switch from indoor to outdoor panels but I have a restricted fixed space.

I came across some 1/16 modules but am wondering if there are any 1/8 or evan 1/4 available.

Would the brightness change be visible with the 1/16 ones compared to 1/32?

Appreciate any help

any time you lower x for 1/x, it will be brighter for sure.
1/8 and 1/4 can be supported as long you don’t have too many lines (for instance I’m not sure 1/4 64x64 works unless they have very long lines internally, like 16 lines of 256 pixels)
