Samsung QD OLED

High Hz on OLED produce excellent strobeless motion blur reduction with fast GtG pixel response. It is easier to tell apart 60Hz vs 120Hz vs 240Hz on OLED than LCD, and more visible to mainstream. Includes WOLED and QD-OLED displays.

I hear people are complaining about PWM dimming. That is a big no-no! https://youtu.be/pqFCg0PZwOk?t=350 Text clarity/pixel layout is also no good.
Not personally noticed any flicker if PWM even down to 60hz. Also text clarity seems perfectly fine (but same again about sensitivity). You can clearly see in some areas/circumstances the pitfall of the triangular sub-pixel layout. E.g white edge on a black horizontal (being the most extreme instance of it) you will see if you get close enough clearly a row of just the green sub-pixels on the top edges and purple on the bottom (from red and blue sub-pixels being side-by-side) but only a sub-pixel thick. Honestly don’t notice it from normal viewing distance though. I have two coding friends (work for Disney) that were hesitant after seeing the sub-pixel layout news come out and clear as day fringing examples being shown (as was I) by earlier Chinese and US customers but since having received their monitors (same time as me) they’ve not looked back. They’re loving the monitor for work, watching and gaming. (They we’re also using 34’’ 3440x1440 curved but IPS before).

All that being said of course, YMMV.

I am curious why they opted for the triangular sub-pixel arrangement though. I presume it had something to do with manufacturability.

I would assume it's adopted from their AMOLED process.

You're probably right.

I know this thing doesn't have BFI built in, so I was curious if anyone who owns it has tried the BFI in retroarch on it? I am really curious to see this thing's motion clarity with BFI.

If it did have BFI it would probably look very similar to LG's C1 or C2, too dim for use - https://static.techspot.com/articles-in ... ges/38.png. We need at least 350 nits panels for BFI to turn out bright enough, this QD OLED is now 250.

The Alienware OLED can reach 1020 nits peak brightness on a small window in HDR1000 mode according to that video from Hardware Unboxed. It would definitely be brighter than the C1 at equivalent BFI/MPRT. The C1 reaches about ~700 nits peak brightness at 1/10% window in HDR mode. SDR/sRGB standard for comparison is 100 nits peak brightness.
350 nits is nowhere near bright enough, and even less so if you're using it for Emulation/Retroarch which I'll assume you're using shaders which dim the image even more.

Problem is that software BFI implementations are dependent on the panel's refresh rate.
The Alienware OLED is limited to 175hz so there's only so much you can do without a built-in hardware BFI/strobe afaik.
