Core i7 4790K integrated graphics not working on Asus Z97-A USB31 motherboard

[Almeus]

I occasionally dabble in Linux, but my GTX 980 TI doesn't play well with Linux, so I've been trying to get my integrated graphics working to no avail.

Intel's product page for the 4790K mentions it has integrated graphics, and the motherboard manual describes options for integrated graphics configuration under System Agent configuration in the BIOS, but some of the options are missing in my installation compared to the manual. Under system agent configuration > graphics configuration I only have primary display and CPU graphics multimonitor, which leaves out the CPU graphics memory and render standby options.

I've tried removing the graphics card and resetting the CMOS config using the shunt on the motherboard, but there is no output from either the HDMI or DVI ports on the back of the mobo. I've also tried switching from auto to CPU graphics while the the card was inserted, but that didn't work either.

Do you have Bios version 2801 as its latest?

Z97-A/USB 3.1 BIOS 2401
Implement 5th-Generation Intel Core Processors code
*Full support of the new CPU requires VGA driver version 10.18.14.4206 or later
*Before using the 5th Gen Intel Core processors, we suggest that you use USB BIOS Flashback or download ”BIOS updater for 5th Gen Intel Core Processors”to update the BIOS.

hard to install the VGA drivers in Linux I assume since they don't exist.

I know this was over a year ago, but I managed to solve the problem. Turns out it was my monitor. The whatever ROM chip in the monitor that holds the EDID data was dead, probably due to one too many power surges. I downloaded an app to read the EDID data directly and it indicated corruption. I think Windows stores the EDID values in the registry, but Ubuntu/Mint don't, hence why they couldn't figure out the correct resolution but Windows could.

The internal graphics work fine as well.

It ended up being a good excuse to upgrade to 4K.

I picked you as the solution, because although the thread is quite old, you did come back and follow up
Nice one!
I wish more forum posters came back with their results.

Just so you know, you aren't supposed to pick Best Answer unless you are the person who started thread, or was involved in it in some way.. Since I was in thread I probably would have chosen his answer anyway, but don't go around giving BA in threads you not participating in, will just get you in trouble
