Was gonna pick it up at some point anyways. Sure:

Note that this was running with HDR enabled on the Gamer1 preset. (No other settings have been changed. I did do the HDR calibration for Windows when I first set up HDR using the free app from Microsoft, which just steps you through certain screens to set brightness and such.

First two images are at the default brightness 50%. Third image is so you can see the brightness setting in-game, which was perfect at default (any darker and the symbol on the left does disappear completely even though it doesn't really look like it would). Note that because I'm taking these pics with an iPhone, you're going to see a lot of moire pattern artifacts, etc. NONE of that is present in the actual image - it's pristine in person. Also, the reason moire so pronounced for the second image is the sun (and HDR elements in general) are BRIGHT. I caught myself flinching at a few scenes like this one and when some sparks fly.

For the last 6 images, there's a similar shot done at the 50% brightness (as shown in the screen), and then again at 100% brightness (where all the three symbols look similarly bright). 100 is very washed out in comparison and clearly not how the game is designed/meant to be played. If someone hated the dark or had an actual phobia, it would certainly be playable, but IMO the default 50% setting is the way it's meant to be played. You could raise it a few notches if you found it preferable. Another way to go would be using the Gamer2 HDR preset, which raises the overall gamma a good bit and increases color saturation as well (I didn't take comparison pics of that, but I did try it just to see).

[EDIT: Grrr...it messed up my order when I viewed the post, but you can go by file name and I'm sure tell the difference.]

It is a dark game, and there are areas you can't see well, but by design (such as blackouts). Once you get a weapon, you also get a flashlight. Personally speaking, I think it looked gorgeous on this display, and brightening it up multiple ways (in-game setting or different mode on the monitor) is certainly more than possible if that's your preference. Obviously, just my opinion, but being the second native HDR title I've tried (the first being Cyberpunk 2077), I've been impressed by both. The only HDR I've been disappointed with so far is the "Auto HDR" feature of Windows 11, where it tries to convert SDR games to HDR, and I think that's the tech involved, not the monitor (I tend to like SDR in SDR anyways). The SDR games I've tried are looking great in the Calibrated mode (and looked very good in sRGB out of the box too).

On a sidenote, I did discover in Windows 11 there's an XBOX Gamebar toggle where you can quickly switch between SDR and HDR - it's Windows Key + Alt + B.

Whenever you see adjusting image like this in HDR/SDR setting even it calls "brightness", it is set to only make sure the lowlight/black level isn't lifted.

Gotcha - good to know and that makes sense.

Generally I've left these about the default for most games (console too) unless it was way brighter than the image on the left. In this case, like I said, even if you go down to just 49 from 50, it completely disappears, so it's got the black "floor" perfect. I'm wondering if that's because of the "Windows HDR Calibration" app where you eyeball in this stuff (black floor, white ceiling, etc.).

HDR image can disappear like that completely..

Windows HDR Calibration only makes sure there is no highlight clipping, no lowlight blackcrush. It compresses the image within the range of the display so highlight has outlines while lowlight has silhouette.
 
At 240Hz on OLED is there advantage in running BFI at 120Hz instead? Presumably if you can't hit 240 then you may as well. Can this do BFI@120 given the lack of support on the more recent lg tv's?

Yes and no.
It depends on the pulse length.

Blur Busters Law: Display motion blur is based on pixel visibility time.

1ms of pixel visibility time translates to 1 pixel of motion blur per 1000 pixels/sec.

TL;DR Best case motion clarity during GtG=0 and framerate=Hz:
1. Sample and hold motion blur is frametime.
2. Strobed motion blur is pulsetime.

So BFI would need to be flashed less than 1/240sec to have less motion blur than 240fps 240Hz unstrobed.

Sample and hold motion clarity is most efficient at GtG near 0, which is why 240fps 240Hz OLED has better motion clarity than 360fps 360Hz LCD.

No OLED monitor is capable of any BFI as far as I know, and the last TV that could do it at 120Hz was the LG C1 which is probably impossible to find brand new by now. Sucks because I feel like OLED was the perfect tech to pair with BFI.

I'm pressing hard for BFI eventually in OLED, but it won't be in this first generation of 240Hz OLEDs at this time.

That being said -- long term, strobeless blur reduction will be the way to go. BFI will be mainly useful only for framerate-limited content (retro content, video content), when all PC games implement this technology. An RTX 4090 can now do 4K 1000fps 1000Hz with that new reprojection software technology, ported from VR. Doing 1ms MPRT ergonomically strobelessly with the same motion clarity as strobing is now within the window of this decade's technology -- at least for PC gaming.
 
I think one of the major things making BFI on OLEDs like these less practical is there's a hit to brightness using it due to the black frames, the greater the number, the greater the brightness hit...and these can't really afford much of a brightness hit by their nature.
 
Wouldn't they just raise the brightness to compensate? What's the effect of duty cycle on burn-in and power use for an oled pixel?
 
I'm not sure if they could raise the brightness that far or not since brightness has always been a weakness of OLED and anytime you insert the black frames you'd be causing perceived dimming. Those are good questions re duty cycle/etc.
 
I ordered one today it should arrive Wednesday. Hopefully going from 4K 27" to 1440P 27" doesn't bother me too much.
 
I wonder if its possible to remove the AG coating on this screen like we used to. I'm really struggling on if I want to get one or not, my FO48U is simply too big for me but the other monitors I have look so damn bad.

For example, I have a Dell 1440p 165hz IPS panel and even at 80% brightness its dim and hard to see and to be honest the AG coating on it is worse than straight up glossy because it smears the light from windows across the whole screen, I find myself squinting and leaning forward all the time when playing a game trying to see past the glare.
 
A few more observations that people might find interesting:

First, regarding Gamer 1 mode vs. the other modes.
- I actually didn't realize this, but the SDR Gamer 1 mode (I'm guessing maybe the other game modes too but I'm not positive) do NOT dim down with Automatic Brightness Limiting on a full white screen. sRGB, Calibration 1 & 2, etc. all DO exhibit ABL and dim down though, so if you want none of it, you need to use Gamer mode. I'm assuming this also extends to the HDR Gamer modes and probably explains why I haven't seen any dimming in HDR games.
- Gamer also enables DAS Mode, which isn't available in the other modes. That's supposed to reduce input lag but I can't say I notice much of a difference personally. If there is one, it's subtle.
- Gamer 1 mode is in a wide-rage P3-D65 mode, and that can't be changed to sRGB unfortunately within the monitor settings (if, say, you wanted to take advantage of DAS Mode or the lack of ABL). So SDR games are going to look extra saturated/vibrant using it (not necessarily desirable if you prefer accuracy and realistic colors). That said, there are utilities that can accomplish this by clamping it to sRGB in software (novideo_srgb is one, at least if you're running nVidia hardware), but it's unfortunate you can't customize it in the monitor controls.

I'm very pleased by the calibration I did to Calibration 1. I do wish LG would allow either:
1.) The import of a calibrated profile to the Gamer modes, so you can still have the lack of ABL and use things like DAS Mode; you should also be able to manually set color space
OR:
2.) The ability to set things in the Calibration modes like ABL to off (and DAS to on, though that's less important to me).
3.) I'd also like to see the SDR Calibration carry over to HDR modes. Sony does this on some of their TV's by carrying over the SDR calibration and adjusting HDR colors based on that, and it works well.

Fortunately, things in the HDR Gamer mode (I prefer Gamer 1 - Gamer 2 lifts blacks too much, even if it has a bit more pop) seem to reflect fairly accurate colors using the Windows 11 Auto HDR feature, even if extrapolated from sRGB. (I don't usually do this myself, but I tested it just to see how it looked).

All of that said, these are more just things I've found interesting - still very pleased with the monitor. Deciding now if I want to use clamped Gamer 1 mode or the Calibrated mode for SDR games and content, but leaning towards Calibrated (at least at this moment, though the lack of ABL altogether is super tempting =oP).

Even though Dough has a slightly tarnished reputation right now. But you might want to look at their glossy version of this display.

https://www.dough.tech/pages/spectrum-glossy-oled-qhd-240hz-monitor
 
I have to think it'd be insane with all of the requests for glossy for nobody to do it...

The Dough information is pretty discouraging. Maybe they'll get it together, but I'm not gonna hold my breath.

Is it confirmed the Asus model that uses this same panel will be matte?

Bad logistics and bad business practices, but their products have reviewed decently. The company has been renamed, it used to be called Eve, if you ever heard of Eve Spectrum monitors they were all the hype about 2 years ago.

A BFI-capable OLED monitor that goes down to 60hz single strobe is an instant buy for me. Especially if it allows for the pulse width tweaking ala Viewsonic XG2431.
 
The input lag looks better than I assumed from other comments. Maybe those were only for the Flex?
 
This review was pretty interesting!

The one area that doesn't match my own experience I'd say is use for work/productivity. This being my first OLED as a monitor (I had a TV years ago, but obviously that's a different use case), I'm pleasantly surprised by its performance when working with text and things, and it's something I do a lot. (I also view a fair amount of SDR images and it really shines in that).

There is text fringing, but in the vast majority of cases, I don't notice it unless I'm looking for it. There are exceptions to that (as an example, I have folders in my bookmarks bar in Chrome, and I can see a red edge pretty clearly on the left side of each), but even when I do notice it, it doesn't really bother me. Kind of funny because I'm super sensitive to other things like blooming, panel uniformity issues, or poor viewing angles at the edges of a bigger screen.

Honestly, I find this at least as easy, if not easier, on my eyes as my previous 27" IPS panel, and from brief use, I think it may even be easier on my eyes than the 32" IPS's I tried (some of that might be not being used to the bigger screen tho' - I don't know).

Your mileage may vary. If you're sensitive to text fringing, it may be an issue. But for me I'm actually kind of shocked how much it's not.

Yeah. I really hope they bring BFI back.

Also not crazy about the idea of generated frames...
 
So I currently own a 27 inch acer ips, G sync 165hz that I've been having for many years. I keep debating on whether to update to the next size and oled?? I really only ever do major upgrades not minor but wondering what's out there and the best options?? I'm running a 5800x with 3070ti
 
I might wait around for the 27" ASUS Swift version which uses the same OLED panel but the adjustments might be better but maybe not.

Why just 27? I'm on 27 acer g sync 165hz ips panel and looking to go up on size but stick with 1440p. What would be a noticeable huge upgrade for me? I'm running a 3070ti

These are no way MLA. LG is just straight up lying.

So what exactly is the benefits/advantages of MLA, isn't it supposed to enchant WRGB-OLED to be as good as/surpass QD-OLED ?

Last month folks on AVS were saying at worst MLA would make WRGB rival TCL/JOLED's RGB-OLED.

We can never go wrong with HDR when it comes to OLED. :)

I don't know if I'll like the bigger sizes I would go all out and buy that perfect Dell Alienware 34" but I like tight FOV monitors for faster reaction times.

It's just a setting to match the level of low brightness. It makes sure black level isn't lifted. It doesn't do anything about high brightness though. FALD make that image disappear as well.

Good point I'm in the same boat.. Although I go for ips panels for better colors.

I'll be super curious what the ASUS using this panel will have to offer too.

My understanding is that MLA allows higher brightness and better viewing angles, hopefully with less risk of burn-in as well.
I know brightness is one of the critiques of this monitor, but I gotta say I think bright highlights in HDR look very good (even if tone-mapping is required for high APL scenes), and viewing angles on this thing are insane. Viewing angles are almost like a paper magazine when you look from the side.


This goes over a lot of the technicals.

In my case, upgrading from an old 27" Dell IPS, I tried two 32" panels (an Asus ROG edge-lit, one Asus ProArt FALD) and just wasn't completely happy with them (granted those were 4K, not 1440p). In the ROG case, the panel was fine but I was disappointed by edge-lit, and for the ProArt, blooming was worse than expected and it had a lot of quality control issues that seem to be pretty common for that specific model. It was down to either trying the Asus QX or Samsung G8 (though I wasn't crazy about curved) or going back down to 27", and I think I made the right choice going back to that size but in OLED.

I think the Asus ROG Swift and Strix series have 1440p models, but I haven't had any experience with either of those lines, so I don't know how good they are. I'm less familiar with other manufacturers. Good luck!

I received my display yesterday, initially I was unimpressed with it compared to my X27 and almost boxed it up and returned it. The color accuracy was awful out of the box and everything was noticeably blurry since I moved down to 1440P. After calibrating the display with my Xrite i1 Display Pro the experience did get noticeably better. I still don't think that the Calibrated 27GR95QE is as accurate as the X27 and definately not as accurate as my ProArts.

This display really shines in gaming though. I can't game at Native 1440P there's just too much aliasing for me, so ended up settling with DLDSR 4K for gaming, looks worse than Native 4K but it actually looks pretty good outside of fine details. I tested some games at 160-240Hz such as Fortnite, Hitman 3, Metro Exodus, the motion clarity is on another level with this display, I don't know how to describe it, but it is different than any other display's gaming experience. It honestly felt like the best improvement in gaming experience since the PG278Q and I would assume the Alienware OLED is pretty similar here.

I also tested Elden Ring at 60Hz, the motion clarity of this display makes a 60Hz experience feel more like a 90-120Hz experience. I almost feel as if this display will feel like cheating in fighting games since they are usually locked at 60 FPS and non-OLEDs will have to deal with a significantly longer update.

I feel the HDR is pretty good for content consumption. It's obviously better with blacks than a FALD display, but doesn't hit the brightness that will burn your eyes like a FALD. It was a more comfortable middleground between SDR and HDR. But definitely not a true HDR experience.

As for text fringing, it seems to be unavoidable right now, but can be largely reduced with cleartype and some scaling tweaks.

Glad you're overall liking the monitor, LittleBuddy!

Curious about your poor precalibration results - are you referring to the Gamer presets or sRGB being inaccurate? I have to say after calibration (also with the i1 Display Pro I believe), the sRGB setting (which remains out of the box) seems pretty close to what I got calibrated. I wonder how much variance there is between panels.

It'll be insane if they ever make a 32" 4K model similar to this, but I know 32" OLEDs aren't much of a thing yet.
