The OS4.02 comment didn't sound quite right as I wrote it but that was what
was happening. 

OS4.02 does have 8MB VRAM but the maximum bandwidth settings need to be
increased to access it. The values do not matter much as there is no VIDC to
explode if overworked, an answer of sufficient precision is simply to add a
zero to the existing values.

The file and new line are :-

HostFS::HostFS.$.!Boot.Choices.Boot.PreDesk.Configure.BandLimit

/<Obey$Dir>.BandLimit 380000 760000 1520000 800000


OS4.02 is now displaying at 1920x1080x16m
