What is the max memory aperture for the video memory on the pi 4b 8gb model?

Someone knows? Google is not my friend on this.

I think (not certain) that max is 512 MB.

OK. Ty! I tried 1024 first and got a blank screen. 512 got me a working system again. Much appreciated!

there’s only 1024 shared between gpu & cpu.
anymore than 256, your just wasting it & making your system slower.

cpu is more important than gpu, best to leave at default 64 or comment it out & it will default to 76.

all other specs don’t matter it can not access more than 1024.
