We exist ULMB hacked for allow single-strobe 50Hz! lol
There's a hack for ULMB1 available, but it's still DRM locked to NVIDIA GPUs. Won't work with external 50Hz sources.
I don't know if the ULMB1 hack works on ULMB2 displays to add undocumented ULMB refresh rates.

Do I need RetroTink? But I don't want (retro)gaming for 50Hz but yes multimedia (50fips/fps videos, live TV Portugal...).
Retrotink 4K works with any video source including TV boxes.
Yes, you can do 50Hz BFI with RetroTink as long as you can do a multiple of 50Hz (e.g. 100Hz, 150Hz, 200Hz, 250Hz, etc).
You will have more options with a larger input:output refresh rate ratio.

-> RT4k only but without new monitor!?? If I have CRT monitor, I don't need RT4k!!! New monitor + RT4k cost 1400euro!?! What shameful, confusion and donkey!

In year 1995, Faroudja video processors used to cost over $10,000. Retrotink 4K does everything that old Faroudja could do, but at HD resolutions and at any refresh rate, but with additional features like CRT filters and BFI.
It's expensive but a bargain because you bring your own BFI to any display that does not have BFI. In fact, the BFI of Retrotink 4K outperforms the LG firmware BFI, by being lower lag (Even when conneted to the same LG TV) and more adjustable. Custom refresh rate BFI works fine on LG TVs, including 48Hz BFI, 50Hz BFI, 53Hz BFI, 60Hz BFI, thanks to the "fixed framerate BFI trick inside a VRR signal". Basically, Retrotink 4K can transport its software-injection BFI over a VRR conduit, to enable custom BFI refresh rates on LG HDTVs not normally otherwise supported.
It'll even do 35mm projector simulation, doing 24Hz doublestrobe (48Hz flicker inside a 96fps-in-120Hz VRR signal). Which means you can plug in a VHS or Laserdisc with 3:2 pulldown judder, the Retrotink4K will deinterlace 480i to 480p, scale it to 1080p, dejudder it to 24Hz (24p) and inject BFI (single, double, triple strobe), giving you 35mm projector simulation to any retro home theater device. Yes, BluRay players work (as long as you use HDMI stripper). No product on the market can do this. No TV firmware on the market can do this. It's got a monopoly on that feature, courtesy Chief Blur Buster -- nobody else knew how to pull this off. In that point of view, $750 is such an incredible bargain because it is used by the market that used to be dominated by $10,000 video processors by Runco and Faroudja in the 1990s (that only did scaling or line doubling, not even dejudder).
It's overkill for many people, but the only option for other people.
