GetSupportedFullScreenResolutions returns 0x0 on Intel Graphics cards of users.

GetSupportedFullScreenResolutions returns 0x0 on Intel Graphics cards of users. We use GetSupportedFullScreenResolutions and in every user with a offboard GPU it works perfectly but if the user has a onboard GPU like Intel HD Graphics it returns 0x0 instead of valid resolutions. :confused: Anyone knows something about that?

Hey Charles,

Depending on how that function works, it might be looking for a dedicated GPU to be able to find the compatible resolutions. Could you provide me with the ‘dxdiag’ or system specs of one of the machines with the HD graphics cards?

I just read our documentation and it says for the boolean, “true if successfully queried the device for available resolutions.” Perhaps the query is failing when checking the device, which then returns a failed 0x0 resolution.

Let me know if you have additional questions or comments.

Cheers,

I just ran a test on my end in 4.14 in a blueprint project on a Mac that allows for graphics switching between integrated and dedicated GPU. The integrated GPU is an Intel Iris Pro, and the dedicated GPU is a Nvidia 750m.

Both instances provided me with the expected results. Below is the visual script I put together to test this function.

Perhaps you are calling it incorrectly within code? Would you mind testing a new blank project to let me know if it occurs there as well?

Thank you,

Are you testing with the game packed? We only could reproduce this way.

I tested in a packaged build, and it still returned the acceptable resolutions as expected.

Can you provide me with the packaging settings you used so I can replicate the issue on my end?

Thanks,
