Widescreen resolutions with Sun Rays

Is it possible to use widescreen resolutions with Sun Rays?I have a display with 1440x900 resolution but utresadm says "1440x900: object not found". Can I add it somewhere?

You'll need to use utresdef to first define the screen resolution. Then you can apply that resolution to the dtu. See the examples posted in the comments section of this blog: http://blogs.sun.com/roller/page/tdh?entry=the_monster_got_a_computer

Did you get this working? If not, then what refresh rate does your display expect?
