Thanks for all the help guys.
I’ve been tweaking whit the menu.dat and the otwfonts.dat file
and finally got the right configuration.
For the menu.dat I edited as follows:
Added to the bottom of the resolution section
#resolution 3840 2160 100 3000 850 3830
And the otwfonts.dat, at the bottom added:
#resolution 3840 2160
#font 0 1 0 14 Arial
#font 1 1 0 9 Arial
#font 2 0 0 9 Arial
#font 3 1 0 9 Arial
#font 4 1 0 12 Aria
Now everything is legible and all commands appear.
Again thanks for all the assistance.
