Hi Tim,
I assume the attached image is your rendered frame (with size 1291x726)?
Please be aware that the screen preview helpers (such as IDeckLinkGLScreenPreviewHelper, and IDeckLinkDX9ScreenPreviewHelper) are by design for small window rendering, the frame is decimated by 1/2 for HD, 1/4 for 4K and 1/8 for 8K by skipping lines, so you may see aliasing if your render window is larger.
For high-fidelity screen previews, please refer to the implementation notes using IDeckLinkScreenPreviewCallback interface in our developer FAQ at https://www.blackmagicdesign.com/support/faq/59024, under heading Full screen preview with DeckLink screen preview helpers.
Regards
Cameron
