Combining XL2720 Blur Reduction with BFI (hybrid of CRT+BFI)

[blurfreeCRTGimp]

I too have tested the newest version of shaderglass on my BenQ XL2720 that I have overclocked to 180 hz. With the standard strobing implementation on this monitor I can resolve 1200 pixels per second in motion, which is insanely good for this monitor.

Here are some pursuit shots that I have taken. 1920 pixels per second panning shots, impossible to resolve on this panel.

I have used the blur reduction mode to overvolt the LEDs to get better brightness. Shots were taken with Iphone from 60 fps video and still shots from 240 fps slow mo recordings.

I am a motion blur snob. I have hated LCDs since 2003 when I first got a 4x3 Xerox 1280x1024 at 60hz. Motion blur and contrast were atrocious. LCDs have remained atrocious.

This BenQ is about 10 years old now? I have enjoyed it overall, especially since Lossless Scaling came out, but I have never seen an LCD at this age able to resolve a 1080p image in motion. I am gobsmacked that this works as well as it does. If you haven't, download it now.

This software purpose to get lower fps content to your monitors max refresh. Not go beyond.
Are you running windows at 180fps and then turning on the software for no benefit? However turning on hardware backlight strobing with sw crt beam is amplifying the clarity boost more than usual?
If you are saying you are getting the latter. Then that's an incredible piece of information worth spreading.

Yes, I believe I am getting 2ms of persistence at 1920 pixels per second when I combine the monitor's hardware strobing with CRT Beam simulation. I have added a couple new pictures to the link. ALL photos are not perfect and were shot free handed on my phone.

1 new picture is my 180hz overclock without any blur reduction at 1920 pixels per second, completely unusable under ordinary circumstances with this monitor.

the other new picture is 180hz at 1920 pixels per second with hardware strobe alone, but the brightness is too low to be of any practical use.

Usually when I use hardware strobe alone at 180hz, I use lossless scaling frame generation to lock my software's frame rate at 180 FPS and I use the strobe utility to set the pulse width to a setting that gives me a good brightness and clarity trade off.

When I do this routine I just mentioned, I can usually only eye track at 1200 pixels per second. I can eye track at 1440 pixels per second if I use hardware strobe alone, but it is way too dark to use, so I never do.

I think I may have stumbled on a blur reduction amplification for my overclocked decade old default LCD 120 hz monitor.

I can eye track at 1920 pixels per second with the monitor at 180hz by combining hardware strobe and CRT Beam Simulator.

Here are two videos of the display in action

There is some red herrings involved here.

I've renamed the thread topic. The reply is at reddit -- he turned off the CRT scan and is using the phosphor simulator for a phosphorescent global BFI. There's better ways to achieve a similar effect without the CRT filter, but there's some usefulness to a hybrid BFI+CRT. Improved motion blur reduction it does not give, but it's all in the settings nuances and how it's configured. The topic title is sensationalism/bait.

Nontheless -- it IS a useful mode of operation (a phosphorescent global BFI).

"Improved motion blur reduction it does not give, but it's all in the settings nuances and how it's configured."

I wouldn't exactly say that my title was red herring, hype, or "bait" that's a bit harsh chief lol. I'm not a computer vision scientist, a physicist, or an engineer. I am a hobbyist. I was sharing MY EXPERIENCES with MY MONITOR.

As I mentioned in the replies in the thread, I have tried your large vertical total tweaks, they do not work well on MY monitor, and I cannot maintain my 180hz overclock with large VT. The double image at high panning speed makes that and low MPRT strobe settings unviable on this 9 year old panel.

I have also tied the standard blur reduction modes that come with the dsiplay as I have tweaked them through strobe utility. I pointed out that even with blur reduction, double image effect largely negated any benefit I was getting from lower strobe duty settings. I happened upon the "Global BFI with phosphor fade" as you call it by fiddling with settings acciedentally.

I called it CRT Beam Simulator because that is what your algorithm is called, and I was describing what I was seeing to the best of my knowledge.

To my eyes, and based on my pursuit shots that I posted on the imgur album shared on the reddit thread I appeared to be getting 2ms of frame persistence without the flaws inherent in my panel of double image ghosting, overshoot, etc. that have made it unusable in the past with your very good conventional advice.

Looking my pursuit shots over, I am not even sure that its a consistent 2ms of persistence across the whole panel, due to the nature of the fade. Still a massive improvement over the default, which is why I was so excited to share my results across several places, apologies for spamming.

Never seen an LCD of this age look this good, even with your suggested tweaks that I have definitely tried over the years.

The only really hard issue for me to pin down as yet in using your algorithm this way has been maintaining the correct colors, and having the right "CRT beam position" setting in the shaderglass slider.
