I have come across a strange issue with the BayTrail E3845 Atom processor where you temporarily lose video output during a Windows 7 logoff or resume from system sleep.
The specifics are:
* OS installation is Windows 7 pro 64bit
* BIOS set to LVDS output
* Panel Auto detect: OFF (as there is no panel EDID present)
* Display resolution set to 1024x768@60Hz
Intel specific graphics drivers tested:
> Intel_EMGD.WIN7_PC_Version_37_15_0_1127 (Intel® Embedded Media and Graphics Configuration Editor for Windows 7 64 Bit Version Number 188.8.131.527); and
> win64_153332 (Intel HD Graphics Driver for Windows 7 and Windows 8 64Bit Rev. 15.33.32)
In the Graphics control panel, the display resolution is set to 1024x768 and configured for a single display.
When you log off Windows or resume from a sleep state, you temporarily lose the video output where I can only describe it as watching the blue fireplace channel.
It happens for anywhere between 1 - 3 minutes before the video output is restored.
Steps to obtain the ‘blue fireplace anomaly’• Boot into Windows• Start menu > Log off OR• Start menu > Sleep (and resume from sleep)
Takes about 1-10 tries to witness it.
