[New LCD device support: Samsung SPF Digital Photo Frames]

That seems like a very useful information, thanks a lot! We've already implemented it in the latest AIDA64 Extreme beta update available at:

http://www.aida64.com/downloads/latesta64xebeta

Let us know if it helps to fix the disconnection issue.

 

If works for me (SPF 107H USB-ID 04e8:2035 / 2036).

Great (and unbelievable short time to make it happen)!

We've extended the update frequency down to 100 msec in the latest beta update to AIDA64 Extreme:

But, I don't think it would help. Please let me know how it works.

 

Concerning the switch back from monitor mode after a couple of seconds for some Samsung SPF I have found on "http://pyframe.blogspot.de/2011_12_01_archive.html" this information (it's from a python script). 

  # This control function is required to keep the frame permanently in Mini Monitor mode. 

  # When the frame is switched to Mini Monitor mode, it remains there for a few seconds, but 

  # then switches back, unregistering from the USB bus.

  # This function is needed only once after connection of the frame, but it does not seem

  # to do any harm when transfered with every picture transfer

  dev.ctrl_transfer(0xc0, 4 )    

 

Perhaps you can add this byte sequence to the contol code sent to the frame, to solve the problem of the not permanent "mini monitor" mode.
