1) Add new def resolution:  --This has been done for the Samsung .  Similar steps must be taken if you need a new resolution for another type of display.

EX)

  $ utresdef -a -c "Samsung 550" samsung1920x1080 1920x1080 << End
  htotal=2576
  hfp=120
  hsyncwidth=208
  vtotal=1118
  vfp=1
  vsyncwidth=3
  vcomposite=8
  pixclock=17280
  xres=1920
  yres=1080
  hz=60
  End

utresdef:  Manages monitor resolution definitions for Sun Ray

...

2) Install the new resolution you have defined

$ utresadm -a -c <CID> -t default samsung1920x1080

Use : utsession -p -This will get you sessions and token ID's   To get the TerminalCID : utsession -lt pseudo.00144f3ba578 -this is "IEEE802.macAddress   This command would set the default resolution for the sunray for the first monitor video output:   utresadm -a -c IEEE802.00144f3ba578 -t default samsung1920x1080 This will set the resolution to the second video output: utresadm -a -v 2 -c IEEE802.00144f3ba578 -t default samsung1920x1080

 

and then power-cycle the Sun Ray.  After it has reconnected to the server, log out -- or if it's a kiosk session, terminate the kiosk session: hold down Control and Alt and hit Backspace twice.

You must use the VGA connector for that timing, its pixel clock is too high for a DVI connector.  (I don't know whether this model has a DVI input, but even if it does you can't use it with that timing.  If DVI is a must then we could probably come up with a 1920x1080@60 timing that uses a lower DVI-compatible clock rate by shaving time out of the blanking intervals.)

***If the TV comes up with the picture not exactly in the center of the TV -try the TV's auto adjust.
