Preview image quality

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.

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.
