Camera shake improves this quite a lot, but still displays banding in some areas so as the highest sharpness loss. Defocus seems to be the best option. Extra output sharpening would increase aliasing artifacts in the first images and would compensate for the defocused version drawbacks.
Experiences or thoughts?

Aliasing and moire on lcd screens is as much trouble as rolling bars on CRTs used to be. And made more complex by the fact that since everything ends up on the Web, viewing screen resolution is uncontrollable.
Some thoughts:
- If the shot has people in it, it’s a lot easier to justify being focused on something other than the screen.
- Filters like Promist can do a lot to mitigate the sharpness that causes moire. You’ll get a bit of halation, but that often works well with a screen.
- Screen replacement is a PIA, but is sometimes a viable option, and you can precisely control the amount and type of blurring you use.
- If I need to shoot on-screen content, and screen capture is not a workable option, I try to shoot tight enough so that the screen pixels are large enough to mitigate the moire problem. It’s often a more impactful shot as well.
- Off-angle shots can be an interesting solution, though they can open another can of worms in that the scale is changing across the shot, and if sharp, moire can show up in some part of the image.
- For stills, focus bracketing is a good tool. (Nikon’s D850 would be a useful tool here.) For motion, not really an option.
