If you have contrary test-data for different VDI bit-depths from:

Tos 1.04 may not work with screen sizes larger than 32KB. Without patches, at
least the mouse drawing routines have problems then IIRC.

TOS v1.04 works fine for me, e.g. in 960x608@4 and 1920x1200@1
resolutions which are nearly 300kB.

But 2.06 and above don't have that restriction.

Besides, as mentioned in the Hatari manual, in monochrome 300kB is
enough for resolutions like FullHD (1920×1080), WUXGA (1920x1200)
and QWXGA (2048x1152), so it's not *that* small...

But only for monochrome. With 16 colors, the largest i can get is 896x672,
that is an annoying restriction.

If you want to propose that to be changed, you need to debug
why GEM apps crash at >300KB sizes and provide a Hatari workaround
for it.

256 colors isn't even supported in TT-mode yet.

Instead of VDI mode on TT, you can use Falcon emulation
and standard Atari tools for setting larger 256-color

--machine falcon --dsp none --fpu internal --cpuclock 32
