Hi,
I've seen a few people have UHD monitors working with their raspberry
pi3's. I'm confused by a constraint that appears to be an X
constraint, and that's the size of the desktop.
Has anyone gotten this to work successfully using an openSUSE build?
This works:
#cvt -r 3840 2160 60
#xrandr --newmode "3840x2160" 533.00 3840 3888 3920 4000 2160 2163
2168 2222 +hsync -vsync
#xrandr --addmode HDMI-1 3840x2160
This doesn't:
#xrandr --output HDMI-1 --mode "3840x2160" --rate 60 --fb 4096x4096 --
panning 4096x4096
error is:
xrandr: screen cannot be larger than 2048x2048 (desired size
4096x4096)
How do I change the default to something larger than 2048x2048
(desired is 4096x4096)?
Is there a way to change it dynamically, or do I need to do some work
with xorg.conf files?

4k @ 60fps is more than HDMI 1.3 can handle. You can either do 2560x1440@60p
or 3840x2160@30p.
Kind regards,

Ah, I should have looked at the hardware itself.
My apologies for the noise.
Thank you for your guidance.
Kind regards,

When I set the resolution to 2560x1440 (or the 3840x2160), it still
tells me:
xrandr --output HDMI-1 --mode "2560x1440_60.0" --rate 60
xrandr: screen cannot be larger than 2048x2048 (desired size
2560x1440)
I think X itself is constraining the desktop size, does that sound
plausible?
I have not tried a newer install yet, this one is still from June.

Stefan,
Thank you for your help so far. Can you help me to understand why the
Pi images X configurations only show a maximum size of 2048x2048 when
with os42.3 on Intel it supports 32767x32767:
smoring@os423happylappy:~> xrandr
Screen 0: minimum 8 x 8, current 1366 x 768, maximum 32767 x 32767
....
