Dell FX100 Zero Client Logon Screen

I have a few Dell FX100 zero clients that I'm testing in my View 5 environment and have  discovered a fundamental problem.  When users disconnect their sessions, the zero client falls back to the View logon screen.  That logon window sits there, indefinitely and is causing screen burn-in.  Is there a power save feature that will put the display to sleep to avoid burn-in? I looked on the Teradici site but didn't see anything.  I'm running the latest Teradici firmware, 3.5.
