Yes, OD Gain adjustability during VRR strobe.
Strobed OD Gain offsets are necessary for improving strobed VRR because of factors like user preference, framerate ranges and panel temperature (colder computer rooms requires a slightly stronger OD Gain for best overdrive quality). Even when there’s dynamic overdrive (usually varying OD Gain calculated by an algebra algorithm or 2D LUT that is linked to frametime), there should be an OD Gain offset as a compensating factor for panel lottery and panel temperature effects – this can reduce strobe crosstalk noticeably by a few percent.
I have not yet decided if it’ll be an absolute value or an offset value. This will be decided during Project Phase #2.
I’m still in Project Phase #1, awaiting an opening by Suzhou Lehui who’s working on a different issue tracking items in their bug tracking system, before they hit requested firmware changes necessary for me to resume Project Phase 1.
Based on what I know, my opinion is that Suzhou Lehui should continue working on the higher-priority items before resuming work on my initial-internal-development-only strobed VRR pre-requisite firmware changes. Yes, it delays strobed VRR further but everybody unamiously agrees that they should focus on critical priorities first. My time is already retained for strobed VRR. I’m just waiting for Suzhou to finish other important bug fixes.
My last ping indicated they were still several high-priority items in their issue tracking system (the github/bugzilla style system they use). I will ping them again for a time estimate for the internal development firmware with all the Phase #1 changes – then I can proceed with testing what adjustments are optimal while being easiest for users.
Once I see how the panel behaves in early strobed VRR tests – then I can design the adjustments required to tune strobed VRR, while being easy enough for an advanced user or experienced calibrator (e.g. colorimeter user) since DIY strobe tuning is theoretically easier than DIY color tuning with the right motion test patterns invented.
For a timeline – to temper expectations. Since there are 4 project phases (phase 1,2,3,4) to get strobed VRR released to public, it probably won’t be before the end of the year if current ongoing bottlenecks from the triple trifecta (parts shortages, Taiwan pandemic lockdowns, and other priority bugfix items).
