LG 27" 1440p 240hz OLED Ultragear 27GR95QE

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.

Wait a second. Since I switched to CRT I've used either dyac or the g7 anti motion blur 100 percent of the time..

Serious damage to eyes?

My current biggest worry is OLED lag (+1 refresh cycle time versus LCD), but they're working on that.
i've been out of the loop, is there a source on this?

RTINGS, most famously, but most OLED lag tests show this.

And since I work with monitor manufacturers, I know why many OLEDs have to buffer a full refresh cycle, due to ABL behaviors. You need to buffer a whole refresh cycle to do a "Find Brightest Pixels" and "Find Average Picture Brightness" and "Do we have enough voltage/amperage to run this refresh cycle?" algorithms, to output a properly ABL-balanced refresh cycles -- where full white refresh cycles are dimmer than partially-white refresh cycles.

It's possible to remove this (e.g. stable brightness modes etc), but that comes at various tradeoffs (e.g. loss of HDR, or a much beefier power supply + lagbehind effect on HDR picture re-levelling).

It will take time for OLED to achieve subrefresh performance.

Hey Cheif, someone said that the mbr like dyac or g7 mbr hurts your eyes? is this true? Mine is on always....

Also - Do you personally think I should get this 27 inch lg oled over my current 240 g7?

I really just want a fucking CRT 32 inch 1440 - is this the closest and worth a grand? Input lag?

thanks, that makes sense. do you think there's a chance this monitor runs at fixed brightness in some non-hdr "gaming mode"?

Well, there are fixed brightness modes in other OLED products so I would not be surprised if they're included in this upcoming panel.

Whether it reduces lag -- I have no idea. There are many other OLED processing behaviors that can prevent subrefresh processing.

I am worried about this monitor, as I really would probably want to try it out, but I think 200 nits brightness is too low. Is it? I have never heard of monitors having less than 400, and this one has 200. Suppose I have the sun shining at the monitor, will I even be able to see anything? Will I easily see the text on it and the little things (like the shoulders or heads of enemy models) in competitive games?

Isn't 200 nits too few for gaming and work?

I am also worried about the clarity of an image: according to the pictures posted here earlier, in comparison with another IPS/OLED panels, the ufo doesn't look as clear as in this picture of ViewSonic:

I wonder, is OLED really that much blurrier than what ViewSonic has? So yes, it won't have overshoots and ghosting, but the image looks much blurrier to me.

There are two ways to reduce motion blur:

1. Strobe-based motion blur reduction. (XG2431 is superior)
2. Brute framerate-based motion blur reduction. (OLED is superior)

If you like strobing (the art of flickering a backlight to reduce display motion blur), XG2431 is hard to beat for its high configurability.

If you like maximum motion blur reduction without strobing, a 240Hz OLED will easily beat a 360Hz LCD (strobing=off). I'd daresay it will even beat a 500Hz IPS LCD. If you like ergonomic strobeless PWM-free motion blur reduction, I haven't seen anything better than an OLED. It's also very hard to get 400-nit strobing with most LCDs too, so retaining all of OLED's brightness capability...

OLEDs follows Blur Busters Law virtually perfectly, thanks to their near-zero GtG, and the only blur seen is MPRT blur, rather than GtG and MPRT blur combined.

Long term, low-persistence via sample and hold is the Holy Grail. But it definitely does require very high frame rates. Halving strobed motion blur is simply halving a pulse width, but halving unstrobed motion blur requires double frame rate at double Hz.

I pre-ordered mine, I wanted a 1440p monitor as 4K will be too taxing on games fps. January can't come soon enough

4K isn't taxing anything on its own. You also can use a lower resolution if you prefer. It is just the maximum capability, not the only resolution you can choose from. So it shouldn't be a limiting factor on its own, in my humble opinion.
