Create Swap Chain Failed 2.0 - c++

Question

I had a problem with my D3D11CreateDeviceAndSwapChain(). I thought I got a solution in a prev thread, so I already marked it as solved. [Create Swap Chain Failed
Looks like I fooled myself when I accidentally returned the HRESULT as a bool...
I been fighting this problem all day & still have not figured it out. Here are bunch of debug info about the inputs & outputs...
1] Taking the advice to use UNKNOWN with a non-null vAdapter:

2] Following the DX sample by leaving it null & using type HARDWARE:

The pics might be enough for someone to spot out the problem, but in case it was something else, code:
// This is some relevant stuff [anything referenced] in the class.

deviceContext=NULL;

Thanks for reading. Hope a solution is found this time.

Answer 1

Copy and Paste from my comment: "Also, a quick peek at my code shows that I use DXGI_FORMAT_R8G8B8A8_UNORM, although I currently have no clue whether that's the correct mode.". Ok, so it's in an answer now :-)
Yeah, the formats... the DXGI_FORMAT is a rather large enumeration, but in many situations only certain formats are allowed. It shouldn't be too surprising that only certain formats are allowed for displaying, whether it's fullscreen or not.
I got the value that I used from the docs (as usual), specifically the list in the DXGI_MODE_DESC description. I don't actually know whether I'm creating a blt-block transfer swapchain, but decided that these values are as good as any to start with, and even though I don't care about feature level 9 it seemed pretty safe :-)
I have no idea why your code seemed to work wit a null-adapter; I think that's confusing. Maybe the debug runtime would have caught it?

Answer 2

Switching to that color mode [DXGI_FORMAT_R8G8B8A8_UNORM] worked. I get S_OK now. Why do the other color modes exist if they dont work?
