I have had success using IE, Firefox, and Chrome. Have you tried changing the resolution? Are there any scroll bars within the browser? Tried zooming out with CTRL and mouse wheel?
I'm having a fiddle with our system and putting in an X1026 as a test before we use more. I've gotten it into managed mode and logged on but working through the set up wizard the final option to finnish is off the bottom of the screen on the laptop browser I use for this type of stuff. It is the same in IE Explorer and Firefox Is there a recommended browser  that avoids this or some other fix? TVM all
X1026 set up
