The PCH is Q87, CPU is Haswell DT CPU,
There isn't have local panel, Our primary display output is through DVI interface.
The system OS is Windows 7 SP1
We uses Intel generic graphics driver 10.18.10.3325 and VBIOS/GOP.
Now, We encounter the trouble when connect the HDMI is secondly display output.
Current setting Port B is DVI output and define to primary output,
Port C is HDMI and define to secondly output.
If we connect DVI(primary) and HDMI(secondly) device at the same time and switch display output by "WinKey" + P,
The expect behavior should be DVI device ouput when set LCD only, and HDMI ouput when set projector only,
3325 is a pretty old driver. I suggest trying the latest driver and seeing if you issue still occurs:
Hi Michael Coppock,
Nice to meet you,
I have tested what you say gfx driver, but the result still the same, issue still occurred.
By the way, Do you know the Intel BMP utility ?
If you known this, Can you tell me how could I settings the "Display Device Toggle Lists" ?
All the best,
Sorry for not replying sooner, I am, very busy right now. I am trying to get a hold of someone on the display side of the driver team to help you. This forum is for Game Developers optimizing their games for Intel graphics, which is where my expertise is. I have used the BMP tool but not in many years so I need to find someone who can help.
