Thanks for the help. I missed that DVID spec, #&@#*#. That's what I get for just assuming all DVID would be the same, as my 4yr old existing setup is using DVID to 2560x1440@60 just fine.
So I've got all the latest drivers installed (including that intel hd graphics from their site).
This is what I've found:
1: I found a GPU Multi Monitor in the bios and it was disabled. I turned on. Confusing since I did already have onboard graphics working in the basic sense.
2: Somewhere else in the bios was a setting for graphics and I could choose between PCIExpress and Onboard. It was set to PCIExpress and I switched to onboard. This also confusing since there are no external graphics cards installed.
3: Using the HDMI (Board)->HDMI (Monitor) I am able to get to full 2560x1440@60 resolution. And it did so all automatically.
4: DisplayPort->DisplayPort is DEAD. I can't get anything to show up on the monitor.
5: DisplayPort -> HDMI (adapter cable) does work, but only upto 1080p.
6: Custom Resolution in intel graphics appears to be a completely useless feature always reporting maximum bandwidth exceeded. Even setting up a custom resolution for what is already there fails!!! This is very commonly reported problem.
7: I can switch cables/monitors on back of pc and windows detects my changes. But only for dvid and hdmi. The displayport is such a headache and doesn't work even after a full power off reboot (and the monitor is on before the pc). All I can get out of displayport is lower resolution via a DP/HDMI cable.
How can I make use of the display port output? A lot of people are reporting displayport issues (but most seem related to it not coming back on after sleep). I can't even get displayport to work at all directly or fully through that hdmi adapter. I'd really like to at least try and get two of my Asus PB278Q monitors running off the onboard graphics at their 2560x1440 resolution.
