Hi jgrob, I have some questions in regards of your issue:
Does the issue occur when only using Intel® HD Graphics 4600? (With the discrete graphics cards removed for troubleshooting purposes)
Are you using any adapter cables?
Please provide the power supply wattage or model, the Intel® HD Graphics report, and DxDiag report (press Windows* key + R key, type “dxdiag”, press OK and then click “Save All Information”) You may attach the files with the Advanced Editor.
You may want to check the following document: Graphics — Errors Reported By Microsoft*
Answering your questions and some update.
I have the latest ASUS Bios and the graphics settings are all "AUTO" except for the one required to have additional graphics GPUs installed.
I tried setting the memory available to the 4600 to maximum and that actually made it worse. I set it back to AUTO.
I do not do any overeclocking and run my computer with default BIOS configurations except for the drives and that one Graphic setting.
Important. I do have a Samsung 500GB SSD for the C: drive. Only the OS and the MS mandated stuff is on that. I keep all data on three other 3TB drives. But there are settings in the Samsung software to change the computer configuration to work best with the SSD. Settings:
Rapid Mode Enabled (uses some memory for cache)
Hibernation Mode is enabled.
Paging file is set to initial of 200MB and max of 1GB.
Indexing service is enabled
Write cache buffer is enabled
Write cache buffer flushing is enabled.
In power options, "Samsung High Performance" is active
The power supply is a Corsair HX850 (850 watt)
The only adapter I used was one HDMI to DVI cable and that was on one of the NVIDA cards.
I checked the document you referred me to and I have done everything they suggest and I have the latest .NET as well as the latest Intel driver from ASUS which is 10.18.10.3621.
I am now running with only two montors (both ASUS PB278 2560 X 1440 Rez). Both on the 4600, one Display Port and the other HDMI.
Problem still exists.
I removed the two NVIDA cards but I did not change the Bios setting to remove the external GPU checkbox or remove the NVIDA software and drivers.
I captured two DxDiag reports. One with 5 monitors and one with two montiors both on the 4600.
Thanks for the information; it has been very helpful for our research.
You mentioned before that the connections are HDMI and DP but are these direct connections? Are you using any passive or active adapter?
There are some other recommendations I would like you to try:
- Update the BIOS on your computer to latest.
- Install the monitor drivers.
Once you have done the previous two steps, can you also add here your graphics report?
How to get it?
Graphics Report: Right click on desktop> Graphics Properties> Options> Drop Down Menu> Information Center> Save> Open .txt file created> Copy/Paste here.
I too seem to have this issue with HP zbook 15 G2 on Win8.1 x64. Seems ok on single built in display. Anyone get an answer on this? The zbook is completely up to date BIOS/drivers everything.
