That's the simple TL;DR. However, a 50%:50% BFI only reduces blur by 50%. You can do 25%:75% BFI where 1/4th of frametime is visible. That reduces motion blur by 75%. Motion blur reduction will be proportional to visible:black. See testufo.com/blackframes to compare multiple kinds of BFI.

You could simulate a 45Hz impulsed display at 90Hz, but that would be very flickery. It won’t help 60fps content, so you’d need 45fps content. Better to have a >2:1 ratio, but minimum would be 2:1 to be really useful.

The handheld has a HTML viewer that accesses Nintendo's site and interfaces. That HTML viewer is complete enough to run TestUFO. Some people hacked it to point to a different site, through various things like changing DNS settings to load a different "home page" of your own preferred HTTP address

Mike (Retrotink) and Bob (RetroRGB) now has access to the private beta test of TestUFO CRT Simulator -- much more user friendly than Shadertoy with automatic Hz config.

Yes, slipped to June, but...

- TestUFO gained WebGL support and I just got CRT electron beam simulator working on a beta TestUFO server, with a number of improvements. I will announce it this month.

- I'm continuing to work on this project now, after a number of client obligations!

Keep tuned.

Hello Bob.
I am at DisplayWeek 2025.
I have some updates to the CRT beam simulator, as well as a Blur Busters article on BFI/CRT simulator coming out this month. I will answer your BFI questions right after!
How long will you have the 480Hz monitor?

I'm rooting for Gecko too!
They're still slogging away slowly on various HDR-prerequisite work: bugzilla.mozilla.org/show_bug.cgi...
I guesstimate it is probably a year-ish behind.
