I have implemented an application based on CapturePreviewCSharp that displays a preview from a HDMI input on a DeckLink QUAD HDMI Capture Card. On the input I have a 1080p signal from a PC.

The problem I am having is that the image quality in the preview is not as the original - the resolution seems much lower. I cannot figure out is the quality drop produced by the PreviewWindow control or the IDeckLinkDX9ScreenPreviewHelper since I cannot find any settings regarding the quality.

I don't know if you have to stop using direct 3d and implement something like open gl or under it, which is direct3d, so you can get the image with all the quality.
Attached preview.

They will have some example, in the sdk manual I see everything very reduced, please or
Could you please explain why the image quality is not as original and which component is the cause? Also, can I get a preview in full quality?

Thank you in advance.
