ZBook Graphics and Primary Display

[questionsforhp]

Have you made any progress with your your graphics since your post in November?

What are you seeing in device manager for display adapters?

What are you seeing in the bios under advance tab then hybrid graphics?

I too would like to better understand the graphics methodology in the zbooks.

When you have a dreamcolor unit the units often come with an Intel chips that have optimus graphics.  The Optimus technology ordinarily would allow lower battery consumption using the intel graphics instead of the designated graphics card.  It would allow it to be energy star qualified.   However the Intel graphics as of G2 units could not be used on dreamcolor units.  The tradeoff with dreamcolor is the loss of hybrid graphics and the reduction in the number of supported external monitors.

When testing the computer hardware in the bios UEFI extensive or loop until failure disgnostics unfortunately all of the individual graphics cards cannot be tested like the individual solid state or internal hard drives.  When the UEFI tests pass it is unclear whether the Intel graphics or the NVIDIA graphics was tested.  When component testing is done there is no choice to choose the intel or the NVIDIA.

For your system it seems you have three graphics, Intel hybrid, NVIDIA and AMD.  So I was wondering what you can and cannot test using the UEFI diagnostics to differentiate each of the three graphic components.

With two discreet video cards are you getting more bandwith to run multiple monitors?  Have you been able to run either more monitors than supported or run more higher resolution monitors beyond the supported area?

I learned I do not have the dreamcolor screen, and the intel HD 520 not the invidia HD 520. In the device manager I see the intel HD 520 and the AMD FirePro W4190M. UEFI test runs without error. Sometimes instead of the AMD FirePro W4190M I see an AMD Radeon R7 M350. Incorrect video memory is also reported. Latest BIOS 01.13 A 1, and all softpaq updates installed. Still having issues trying to get program's to leverage the AMD FirePro W4190M. Had a repair technician out 2 times to diagnose a flickering screen issue. The technician is scheduled a 3rd time to replace main board and screen. Will update if new main board solves issue of not being able to use the AMD FirePro W4190M.

New main board and display has resolved screen flickering issue. However the driver softpaq installs for the FirePro w4190m does not work correctly. At each start up the computer fails to see installed hardware and requests to restart to save hardware changes. This just repeats. Using a manually downloaded drivers from HP has same result. Using driver for the FirePro w4190m from AMD won't utilize switchable graphics. Using AMD auto detect installs drivers for the AMD Radeon R7 M350. BIOS 01.13 won't let me disable switchable graphics. Opening a second repair ticket for switchable graphics issue.
