How did it fail? Can you give us more details?

[TienFu Chen (ctf)]

There's no output from VGA in extended mode, no error message shown.
I will try to get the more log when I can reach the machine.

[Anthony Wong (anthonywong)]

Likely a duplicate of bug 830949.

@ctf
Can confirm this bug only happens in Unity 3D but not in Unity 2D?

[TienFu Chen (ctf)]

The unit was already sent back to OEM, so I can't verify it. I have talked to PM, if we can an 1215p for testing.

[Ara Pulido (ara)]

I am following up as well on this issue. We will get some systems soon.

[Ara Pulido (ara)]

Marking back as Triaged, to avoid expiration.

[Ara Pulido (ara)]

Tim, can you follow up on this bug, please? Now that we have the systems back

[TienFu Chen (ctf)]

the system has been sent to repair again, still waiting for the system.

[Greg Vallande (gvallande)]

Tim,

   I've confirmed on the 1215p that the external display mode doesn't work properly. Also note that if you change the resolution to 800x600 (for both displays) - that will work but nothing greater than 800x600. I tested each individual mode and each time I'm prompted with a dialog box that i've attached. (screenshot).

[Greg Vallande (gvallande)]

Tim,

   Also one step further, I tested in 2D mode per the dialog box's suggestion and each external mode worked in 2D only.

[Greg Vallande (gvallande)]

Tim,

   After changing the window geometry and I was able to set the resolution to 1024x768 (with the monitor above not to the left or right).

[Anthony Wong (anthonywong)]

Ara, this bug has been "fixed", by limiting the possible resolutions in extend mode.
