Potentially low MPRT on Samsung QLED 4K TVs QN90D and QN95D + 8K QN900A/B/C/D models

OLED will never go beyond Plasma-level motion

Um.... "Depends on OLED Hz"

My desktop 480Hz successfully has less motion blur than my old Pioneer Kuro plasma display, since 2ms MPRT is less blur than the 3ms phosphor, but only for 480fps content. But I can also now run a new CRT simulator to reduce motion blur by up to 87.5% for 60fps content running at 480Hz.

We're migrating to BYOA. Bring Your Own Algorithm today. With my open source shaders.

We're implementing it into Retrotink 4K now as we speak, I'm working with Mike.

Motion Blur Reduction Video Processors

Future video processors will let you beat certain lineitems of TV firmware BFI, simply by piggybacking on brute Hz. In fact, Retrotink box-in-the-middle 4K BFI is brighter and lower lag than the LG built-in BFI too! (We found ways to do that). The nice thing is that with Blur Buster's migration to the new approach for 2030s, is that we only need generic Hz. In the future, I can reduce almost 90% of 60fps motion blur with a box between your PC and display.

Vendors reading this, I've worked with video processors and line doublers since year 2001. Key Digital LEEZA, TAW ROCK, Runco, and a Faroudja Fli2200-based PCI card, plus I created an open source 3:2 deinterlace algorithm for dTV/dScaler in year 2001. I can now motion blur reduce via box-in-middle approaches. Vendors can reach out to me at blurbusters.com/about/contacct

Anyway, I have no means to go test these sets in a store or anything, I might pick a QN90D if I find one on sale

If you purchase LCD strobing, make sure you check the strobe crosstalk (top/bottom may have more double image artifacts than center). You often can solve that using refresh rate headroom (like Large Vertical Total tricks, or NVIDIA-quality strobe tuning, etc).

Yeah but the amount of money you are charging to do this is too high.

Those Retrotink box costs like $700 US when people hear blur reduction box they are thinking of like $200

So as of now this stuff is all niche really unless Nvidia manages to offer 60HZ Gsync Pulsar or Zowie offers 60HZ DYAC which they probably never will because they are too stubborn

To me the biggest thing has to be G-Sync pulsar because it works with VRR

Why do you use the word "you"?
Please sincerely answer the question.

I don't sell the Retrotink 4K. They simply hired me for some services.

Ooh I thought you were selling it? I thought it was your company that was making it.

No. Just like ViewSonic (separate company), the Retrotink people (separate company too) hired me for some services.

www.retrotink.com is a separate company.

RTings has updated their testing methology.
This is how the Samsung QN90D looks with BFI. (Unknown if the picture shows 60Hz or 120Hz)
It looks very good.

And for comparison, the Dell AW3225QF QD-OLED without BFI at 240Hz/240FPS

And the ViewSonic XG2431, for best-in-class, at 120Hz "Ultra" preset

Crazy thing is, I believe that in TV tests they only show the 60hz BFI picture. This appears to be the case for every TV I know that does both 60hz and 120hz.
Therefore I assume the 120hz BFI image on the QN90D to be superior to this one.
One thing that bums me is that the 60hz BFI picture on the QN95D was clearer still, but that one doesn't do 120hz BFI (and, aside from the gain in potential motion clarity, there is something to be gained to use 120hz/120fps when it comes to gameplay).
Not only that but the QN95D and a few other Samsung models, simply don't boost their brightness when strobing. The QN90D has very high very short peaks.

Whenever a TV is tested as a monitor on RTINGS, you can usually find a 120hz BFI picture (and other compatible refresh). If you look at for instance the LG CX and C1 48" monitors tests, you can find the 120hz BFI picture test and compare it to their standard 60hz BFI test in their TV reviews.

In any case, I'm reeeally looking forward to a bigger LCD with lots of dimming zones and near-CRT motion at 60hz.
My PG27VQ proves LCD can do the job, but the contrast is terrible, I'm really looking forward to the day where I only use it for the occasional 3D dabbling...

[JimProfit]

I feel the need to reiterate one major thing.

The QN900B (8K model from 2022) has a clearer 60hz BFI test picture than the QN90D (on par with the QN95D) and is compatible with 120hz BFI.
Problem is, while it appears a bit brighter in BFI mode than the QN95D, it is noticeably dimmer than the QN90D w/BFI.
Not to mention, both the base brightness potential AND contrast is quite inferior to either 2024 4K models.

This is why I'm waiting to see what 2025 brings us.
They could bring back 120hz BFI on their 8K TVs, a long shot since they didn't bother in their 2023 and 2024 models, but the rest of the specs would be guaranteed to be top of the line.
It would be an expensive purchase to be sure, but the fact that 8K is an integer of 480p would bring it one step closer to being a true CRT "obsoleter".

Or perhaps the pattern emerges that only the QN90F does 120hz BFI, but it could be an improvement on the QN90D in every way.

That would be crazy, indeed.

[JimProfit]

I'm 99% positive. I you look at the BFI graph (just under the BFI picture test), you can see 3 bumps.
Whenever you see the same graph on a 120hz BFI test, you typically see 6 (narrower) peaks.

From what I understand, the higher the peaks, the brighter the impulse are, and the narrower they are, the less frame visibility time they have => the less motion blur there is.

I'm interested in the QN90D and found this thread on Google. Would it be a good choice for retro games such as a docked Analogue Pocket or a mister fpga connected to it?

Would the 120hz bfi introduce too much input lag? I'm very new to a lot of this so please excuse if I'm asking something obvious.
