I have my system setup using the HDMI port to HDMI/DVI adapter to my DVI display 1920 x 1200 and the DP port to DP/HDMI adapter to HDTV 1920 x 1200. And the change resolutions does work on the DVI display but not on the HDTV (as expected in my OP). On the HDTV the when you change from 1920 x 1200 to 1600 x 1200 for example the display loose sync and I have blurred multiple images across the screen.
And the differences in our setup are:
Configuration/Video/IGD Minimum Memory 64MB ; I have 128MB
Configuration/Video/IGD Primary Video Port HDMI; I have AUTO
Configuration/Video/IGD Secondary Video Port None; this line is not listed when above is set to AUTO
Power/Intel Dynamic Power Technology Off; I have Energy Efficient Performance
Power/PCIe ASPM Support Disable; I have Enable
Boot/Boot Menu Type Normal; I have Advanced
Boot/BIOS Setup Auto Entry Enabled; I have Disable
Boot/Boot Display Options/Expansion Card Text Disable; I have Enable
Boot/Boot Display Options/Keyboard Ready Beep Disabled; I have Enable
Of interest I have seen no screen artifacts with HD4000 on this system.
Thanks for the info, much appreciated! I setup my bios just like yours, but I still get the sync issue (just as you described...blurred multiple images..) when changing resolutions. I do not yet have a display port adapter, so I can't test with two screens so see if the second (first?) screen would be free of issues. I too do not see any screen artifacts, just the aforementioned resolution switching issue.
So perhaps my issue is in my configuration.plist. Did you do anything special there to support the video in your setup?
Oh, and how is your build going? Im sure answering all these noob questions is taking away precious build time. Sorry about that.
