Hi,

I purchased two AE-222-095AU AIO PC's for a customer who wanted second screens attached for dual displays.

Both units will not boot with the second screen attached via HMDI out.

It appears to hang in BIOS. When I power on with the second screen, I get the MSI AIO screen logo on the main screen, then the screen goes blank, and nothing happens. No HDD activity to show windows is loading. You have to power off the unit, unplug the HDMI cable either from the external monitor or the back of the AIO, then when you re-boot, it boots fine. Only after the PC has booted, you can plug in the second screen and it will work fine.

I tried the update the BIOS to the latest on-line, but this did not fix the problem.

Is this a known issue and is there a fix? My customer is getting very frustrated with it.

Serial Numbers are:
MSAC11E6S0116794
MSAC11E6S0116791

Dear,

Please check the resolution under external monitor first.
The resolution of external monitor maybe must be higher than 1920*1080.
It is specification for AE222 on MSI website:

Thanks.

So what you are telling me is the machine will hang in BIOS if the external screen does not support 1080p?

Like I said, it is freezing BEFORE windows loads:

With screen disconnected:
1 - MSi AIO logo appears
2 - Flashing text underscore cursor flashes at top of screen for a moment. I am assuming this is the last stage of the BIOS initialization prior to hard drive boot.
3 - Hard Drive light flashes on an off.
4 - Windows loading screen appears.
5 - Windows welcome screen then Windows desktop.
6 - Connect external screen - works fine.

With screen connected:
1 - MSi AIO logo appears
2 - Screen goes blank. No flashing underscore cursor.

Please explain.
Andrew.

Dear,

At POST stage, BIOS will check the resolution for MSI system and second display and both are must be the same resolution.(Duplicate mode)
If the resolution of extend screen is lower than AE222, it has this symptom. (Resolution of AE222 is master. )

It has graphic driver to adjustment automatically under Windows OS that is why it is OK under Windows OS.
