Intel Core i5-3570 - Problem with Intel HD 2500 ( Windows 8.1 )

[RPolß]

Hi,

i have CPU Intel Core i5-3570 and MB Asus P8B75-M.

Intel HD is enabled in the BIOS, set as the primary ( i have R9 280X ), but monitor still going through R9 280X.

Only when I pull R9 280X out from MB, Intel HD turns on.

I need help with this problem.

I need my Intel HD 2500 for OBS Stream, for Quick Sync render.

Thanks !

Hi, Intel® HD Graphics may be set as primary but the BIOS must allow both graphics controllers to operate at the same time.

You may consider updating the BIOS or contacting ASUS* for assistance.

Not all desktop systems support using switchable graphics even with use of additional software.
