Matrix Orbital EVE4-70 LCD keeps going blank this has been occurring since v7.60.7300

[RevJoe]

I been using this LCD for 2 years it's connected directly to the motherboard using a USB 2 SPI options.  This issue presents itself sometime after I lock the desktop, come back an find the Matrix LCD screen black.  Nothing I do gets it going again until I reboot.  Everything works fine after a restart. 

I originally thought it was experimenting Fan Controller or Argus Fan monitor for better control of the water loops and have sense removed them, originally because I thought the apps were fighting over control, removing them did not resolve the this issue, when LCD is displaying the info looks good and is changing. Prior to this those 2 apps would cause the sensors being displayed to stop updating.  Then I tried going back to Aida64 v7.60.7300, but it made no difference.   Works fine until the computer is locked then LCD still goes black at some point.

I don't have any sleep settings or power save stuff enabled. I have disabled power saving options on everything associated with the LCD and USB bus to include the options in device manager. It does the same thing with the Aida64 v7.65.7400 as well.  I will try going back to an earlier version from before 7.60.7300 to see if the issue goes away.  But this makes me wonder if it is a bug in the last 2 versions.

We've tested it, and the screen never goes blank while the system is locked until the point the system goes to sleep.  Then -- since AIDA64 detects when the computer goes to sleep and also when resumes from sleep -- AIDA64 blanks the screen before the computer goes to sleep.  Once the computer resumes from sleep, the screen starts working again.
