- Reduce DVI Frequency on high-resolution displays
- Alternate DVI operational mode

Does any of them equals reduced blanking? Are they able to affect input lag somehow?

Those are old compatibility options.

"Reduce DVI frequency" was meant to work around DVI signal quality issues with 1600x1200 monitors and older video cards, so it should be disabled.

"Alternate DVI operational mode" is coherent mode, which is now the standard operational mode, so it should be enabled.

"LCD standard" in CRU is equivalent to reduced blanking except for TV resolutions like 1080p and 720p, in which case you can use "LCD reduced" for those.

"LCD reduced" reduces the blanking further for higher refresh rates with some resolutions, but that's non-standard.

None of those options have any significant effect on lag.
