Hey Benny!

 BP> its long time since i have see the penguins on gentoo

Same situation here although it didn't really matter as far as working 4k graphics are concerned.

 BP> gentoo splash screens and wallpapers want the penguins to live
 BP> aswell

I am sure it could ( does? ) work.  I'll see what I can find out later.

 BP> you only need kernel boot initramfs to enable it with the mode=
 BP> and vga=

It doesn't work here as those only supply standard resolutions.  4k is not an option.

 BP> want all in fb0 ?

Sure why not?  However xorg still works and "mplayer -vo vdpau -fs movie.mp4" gives a fullscreen 4k on xorg that is worthy of note.  I assume other graphically inclined applications will also work.

 BP> i only have a display port monitor at fullhd, 4k is nice and
 BP> expansive :=)

Yes it is.  For the cost of a half decent 28" 4k monitor I can easily purchace two top-of-the-line 1080p monitors.  As for the 7" monitors I have, the 1080p is definetly the better compared to the 720p.  The smallest REAL 4k monitor I can find is a 12" and they want far too much money for it, almost twice the price of the 28" one I now have.

Four of them?  I am going to have to pass on that.

I am glad I did this as now I know and am content to have one working 4k monitor but I am unlikely to replace it with another.  1080p is more than good enough for my usage for graphics, and is far cheaper.  That is my recommendation at this point in time.

Life is good,
Maurice
