I have hp EliteBook 8470p i5-3320m, 8GB ram, Intel HD 4000 graphic card.
I am trying to play MP4 video 1080p and some are not working properly .
How can I check if I have discrete graphics card of AMD Radeon 7570M or not?
It is not shown in the BIOS or the Windows device manager.
It is possible to upgrade discrete graphic card?
Is there any option to change share memory of Intel graphic card 4000?
If I upgrade 8GB ram to 16GB ram will it improve graphics quality or not?
