Low MPRT strobing LCD TVs (mostly Samsung, some Sony - lots of RTINGS BFI Test image comparisons)

Can you do some 960, 1200, 1440, 1920px/s UFO pursuit photographs of your TV? I'm curious what pulse on interval it can achieve.

I have no practical way to do quality pursuit shots at the moment. However motion clarity on the QN90D has been discussed in this topic not just by me. And do remember that it is highly dependent on how low the brightness is set to (brightness control = backlight pulse width control).
-At 60hz Game Mode, toggling LED Clear Motion at max brightness already yields a level of motion clarity close enough to 400hz/fps, and lowering the brightness further increases motion clarity. Meaning that at 100nits SDR brightness levels, the motion clarity is as good as it gets in a modern TV.
-At 120hz, there is no toggling of a BFI mode but lowering the brightness backlight controls pulse width so in the end it works the same.

There is strobe crosstalk (room temperature dependent), but it is a small price to pay for the motion clarity increase, which is almost unheard of in a TV, let alone one that offers such performance in picture quality.

So, I expect my incoming QN95D to work the same, and hopefully it works even better as its CAD test results were noticeably better on RTINGS. Hopefully, variation between samples is moderate.

It's a shame that the R95H doesn't keep up, I was not planning on being an early adopter of RGB Mini-LED anyway, but seeing the downgrade in its strobing mode makes me glad to have those peak "CRT alternative" regular Mini-LEDs with a glossy finish.

1920 pixel/s on 4k resolution is really slow, isnt that just misleading motion clarity, when the ufo is physically moving slower across the screen

The results for the R95H are very disappointing! The most frustrating part is that the strobe form is probably as good, if not better, than the QN90D/95D, with more brightness headroom, but with such crap response times the ghosting/strobe crosstalk will likely be a dealbreaker.

Also, given the R95H doesn't flicker at 120Hz in game mode anymore, it probably won't allow us to use the brightness trick to shrink the pulse width for 120fps content either, like on the QN90D.

Colour accuracy isn't as important to me, although when it gets this bad maybe even I would notice...

The only remaining hopes would be the Sony Bravia True RGB TVs, which from what we know already probably also have bad response time, and Sony's Clear Motion has never been nearly as good as Samsung's motion options over the last few years anyway. It's possible that the R90H or R85H, by some chance, don't suffer from the same response time issues, but that's a long shot.

Definitely going to hold on to my QN90D! I've accepted a brightness of 12 (/50) for 60fps content, and around 7 (/50) for 120fps content, and my room's space heater keeps the ambient temperature toasty. Personally, don't see enough to justify switching to a QN95D.

Better luck next year I guess!

Better luck next year I guess!

It's been five years since we had an OLED TV with 120hz BFI/Rolling scan BFI that goes beyond motion clarity doubling.
I heard LG has some monitors in the pipeline rumored to bring back the technology but who knows how long until it appears in TVs again.

And sadly it's viewed as a fringe consideration by manufacturers so I am worried that it'll take more than just one year (hence the "impulse" purchases, get it ?).

Just in case there are some people who are still interested and still have a choice between the two, the simplest way to compare the QN90D and QN95D, on paper, is as follows:
-The QN90D will be better in most HDR movies, except maybe the ones featuring a lot of star fields: slightly brighter peaks, slightly better EOTF tracking, slightly better color volume, slightly better black levels, but half the dimming zones hence a bit more clouding.
Brightness in HDR Game Mode is noticeably worse than in normal modes.

-The QN95D is better at being a gaming TV, and as a CRT Emulator: Twice the zone count, so less blooming, which is more integral to the look than the slightly higher contrast ratio of the QN90D.
Better pixel response time yielding better motion clarity at the same strobe timing.
It does have lower peak brightness on very small windows compared to the QN90D, but as bright on a 100% window and noticeably brighter on 50% and 25% windows, which helps real content visibility => full or near full screen brightness is what matters most on impulse displays, not small highlights.
It also has a lot less color banding, again that helps a bit to approximate the CRT look.
It is also brighter in most situations in HDR Game Mode, which is significant once strobing is part of the equation.

-If there are no other options, the QN90F has solid strobing performance, trade blows with both aforementioned TVs and is still readily available, I just think it fails at emulating the CRT look due to its matte coating.

Overall I'd say, in it's niche, the QN90D is an A and the QN95D is an A+, but it's admittedly pretty hair-splitting to upgrade from the former to the latter, both are great and it's not a night and day difference either.

I had the GQ43QN94DAT but i didnt find the strobing performance very good. The pixel transistion time with black was so slow it wasnt usefull for me. For example my Sony W905A has much better pixel transistion time.

That's a bummer. I don't know if the opposite extremes of panel sizes have specific technical differences compared to the more traditional living room sizes models. I don't know about a panel lottery either.

But I do have to ask, bad strobing performance compared to what? The good Sony LCDs are long gone, and no current brands does well on that front. I'm not claiming my Samsungs perform as well as my CRTs or ULMB monitors, but they are far better than my GX and my Kuro.

Even the new R95H which I criticized a few posts ago, is still better than any recent TV by other manufacturers', that I am aware of.
For those of us that have access to RTINGS BFI capture shots, it's still shockingly better than other brands' BFI modes.

Shame that there are no monitors that do great strobing and great local dimming at the same time. A 43" QN90, if working as expected, would have been a great option but I ended up dropping the idea and if your experience is representative of all 43" models then I'm glad I did...

Samsungs TV may be the best modern TVs with strobing but the slow pixel response time with black is really distraction. We are talking about nearly two frames of smearing.

Maybe an alternative is a TV with proper 120Hz strobing. For console gaming you can combine this with frame interpolation. My Hisense allows this and for games which dont need low input lag it is much better than 60Hz sample and hold.

Got any recommendation for me to test it? I check the usual TestUFO Game Motion tests and I'm more thrilled than usual with the results (possibly because we're experiencing a heatwave here and the strobe crosstalk is completely gone).

Everything what has black is a good test for VA panels. I for example played the old Yakuza 3 game and especially at night the Samsung was so slow that i thought i played with motion blur.
