Re: A better BFI (1) - Interlacing and Checkerboarding


Yeah, not even remotely close.
You can easily tell the difference between a low-persistence phosphor CRT monitor(1ms MPRT/1000hz equivalent) to a typical CRT TV which used longer persistence phosphor(which could go as high as 6ms MPRT).
The former is in order of magnitudes smoother than the latter ...

Re: Better BFI Algorithms (Split Blanking / Timings / Progressive / etc)


The biggest problem is most manufacturers don't bother to optimize BFI latency.


And it is the most where the big issue lies for me with BFI. You keep talking about rolling scan and such, but the "industry standard" remains the dangerously sloppy full-frame BFI. If none of my solutions and none ...

Re: Better BFI Algorithms (Split Blanking / Timings / Progressive / etc)


-so much stuff-


First, your entire response is a case of missing the forest for the trees. Second, the tone that you have used here is not really helping your case, to put it nicely.

Let's begin with my point about pixel density. Perfect motion clarity is completely worthless if a person can ...

Re: Better BFI Algorithms (Split Blanking / Timings / Progressive / etc)


I disagree. The monitor and LCD panel manufacturers don't a give toss about framerates. Increasing the panel speed from 60 to 120Hz doesn't add all that much to the cost. What prevents you from seeing 24" 1440p monitors is that monitor manufacturer cannot milk you with insane prices after slapping ...

Re: Better BFI Algorithms (Split Blanking / Timings / Progressive / etc)

I have already provided, hence the original point of this thread, solutions to several specific points of failure with the standard BFI that is still all around us (whole screen approach that is clocked on post-frame) . These are not solutions I have pulled out of my butt either as I had tested them ...

Re: Better BFI Algorithms (Split Blanking / Timings / Progressive / etc)

BFI by itself is not cultism - that is not what I am saying; don't pull a strawman on me, please. What I was saying there is that the phrasing used by some of the BFI supporters suspiciously resembles phrasings that a cultist might use. In other words, I am accusing the people rather than the ...

Re: Better BFI Algorithms (Split Blanking / Timings / Progressive / etc)

I should also note; I have given the UFO test on BFI a try; on all settings that I could try, I have found the BFI based samples to be quite painful to watch, and in some cases it feels like the UFO is hopping from one part of the screen to the next. As a result, the BFI feels slower, one phase ...

Re: Better BFI Algorithms (Split Blanking / Timings / Progressive / etc)

My main point here is: if they are going to bring a remedy to an issue that lacks a proper solution at the time, then they need to be really careful about what kinds of compromises are being shoved to the average user. Sure, people in the know might be able to fine tune things, but it is not a ...

Re: Better BFI Algorithms (Split Blanking / Timings / Progressive / etc)


Now, do you understand yet, why we're big fans of using brute framerate to reduce display motion blur instead of BFI? This is good when the refresh rate and framerate is native (original), like for games and VR.


Putting aside technical differences of perspective, I do understand the value there ...

Re: Better BFI Algorithms (Split Blanking / Timings / Progressive / etc)

With rolling BFI, the one you have shown, does the direction of the scans matter in regards to the positive and negative effects of BFI?

For example, what happens when you have horizontal rolling? I am not sure how it visually changes anything. For one, it can enforce pattern consistency for when ...
