Has a 3 year burn-in and dead pixel warranty, and has HDMI 2.1 unlike the ASUS model with the same panel. A lot to like here assuming it scores well.

I’ve had mine for a few weeks and I really like it. The burn-in warranty&zero dead pixel policy sealed the deal for me. Unfortunately as of right now, the monitor still isn’t detected by iCUE. The buttons aren’t bad at all, but it would be much easier to navigate the settings via iCUE software. But that’s pretty much the only complaint I have to be honest. And sure, it’s not a very bright monitor, but unless you play video games in a sunroom, it should be a non-issue. HDMI 2.1 is definitely very nice to have! Dunno about the PS5, but with my Xbox Series X, the monitor does detect 2160p signal AND HDR works.

Nice, I have just ordered one for myself.

How did you find the HDR quality on PC and XBox? And did you update the monitor to the last firmware? I am wondering if that changes anything.

V102’s changes:

1. Crosshair Icon Style update.
2. Improve Video Source Swapping function.

Hi, when will you received the monitor ? Will the kvm switch be part of the test ? I would like also to get a direct comparison, in term of comment, with the LG and ASUS models when the review is over. Thanks

It says you ordered this over 2 weeks ago. How long does it take to receive a monitor?

We recently received the monitor, but because we have a lot of testing going on now and we have limited resources, we can’t make any promises as to when we’re going to test it. But keep following along to this discussion to keep updated for when we start testing!

I went ahead and bought this because it was $100 off. Really disappointed. Despite having brightness stabilizer on it will still dim the screen sometimes. I’m guessing there’s some kind of motion detection or something going on that I can’t disable. Might be something to test for.

Also, firmware update broke DOS mode so now the bios and Windows boot logo are all stretched out. Not the end of the world but annoying considering it didn’t happen with the stock firmware.

I’ve been using this monitor for two weeks and I’m extremely disappointed. ABL is so aggressive that I had to turn Brightness Stabilizer on. While it looks OK with ABL off (I wish it was like 15% brighter, though), the monitor tends to gradually dim specially around the top corners, creating a subtle vignetting effect that’s turning me crazy. I realize that if I open a fullscreen white image for around 20 seconds, the monitor brightness gets uniform again. Evidently there’s some kind of hidden anti burn in measure that I can’t turn off. It makes white text looks light grey, so now I have perfect blacks but imperfect whites… SMH

I don’t understand how it got so many good reviews. With brightness limiter off it could look great, but as soon as you open a bright image, like a game map or menu, ABL kicks in and everything turns dim, so it’s extremely distracting. I imagine that in other OLED monitors with higher SDR brightness, the fluctuations in brightness are less noticeable.

The problem is that I live in Argentina and my wife brought me the monitor from the US and I can’t return it, so I’m stuck with it. I should have bought the LG with better SDR brightness.

I’ve noticed the exact same thing. The corners and edges dim over time despite having brightness stabilizer on. Monitor is more than bright enough for me with Brightness Stabilizer on if it would only actually stay stable.

I too was very disappointed with the 27QHD240 and ended up returning it. The ABL is extremely unpleasant and with brightness stabilizer on, it simply is not bright enough because of the weird auto dimming thing. While the classic pitch black OLED is beautiful to look at, white screens look seriously yellow and it is revolting. I also found text clarity very lackluster but I suppose that’s to be expected.

To be honest, I don’t know if I would recommend this monitor even if it cost like $200. I’m convinced that anyone praising the monitor is suffering from some serious buyer’s remorse because I can not see a single task that it is good at. Maybe watching media if you are inebriated enough to stand the ABL.

I like it for gaming. The ABL hasn’t bothered me in that context.

For sure, but the problem is that using Windows with ABL on is a nightmare, and this is a monitor, not a TV, so no excuses there. There isn’t even a quick way to toggle ABL on/off, so I have to navigate through the menu to activate ABL when I’m about to play a game. This shouldn’t be happening with a 1000 USD monitor.

Keep in mind that with Brightness Stabilizer ON and normal use, the corners dim, creating a Vignette effect.It goes away when viewing a full screen white image for some time.

I took some photos. The first photo was taken after normal Windows use. The second photo was taken after viewing a 100% white screen for one minute. Is noticeable how uniformly brighter the screen got.

I’m using Standard Setting with 100% brightness, 50% contrast and 100% RGB Color temperature. Using Brightness Stabilizer ON.

EDIT> Someone told me that it’s an anti burn in measure called “Convex Power Control”.

I’ve bought this monitor today and have impressed so far, the juicy OLED color, performance and I hope corsair will figure out something in a next firmware updates to improve the user expirience. The only think I’ve noticed as a not good is that you cant switch on/off the brightness stabilizer fast. The monitor’s brightness iteslf is ok in both and I did not expirience any brightness issues or something

Hi RTINGS.com Team, Can give some more context about the results of the following tests:

• SDR Brightness
• HDR Brightness

Was ABL on or off ? It should be interresting to get the other results (on or off) and add them into the test. Can you confirm or not the behaviour recorded by “monitors unboxed” with brightness: https://youtu.be/ksNCMduj_yc?t=752 ? LG and Asus models does not seem to suffer from that, for LG the results appears to be pretty close.

Also can you also precise the Firmware you used for the test.

Thanks

Hey,

As you can see with the final review in the Brightness sections, we tested it with Brightness Stabilizer off, as using it on severely limits the brightness. We did notice the same thing as Monitors Unboxed with that setting off, and even changing window sizes results in a dimmer screen. You’re right that the ASUS and LG monitors suffered the least from this, and it’s the worst with the Corsair. We also tested it with firmware V102.

Thank you so much. Well, I am totally confused about this monitor. Its general note makes it attractive but I am afraid of being disappointed by this behavior

I have this monitor and my main issue is G-sync brightness flicker. Seems to vary from game to game, but it can be pretty bothersome. I’ve enjoyed using it for everything else. Text is worse than on my IPS 1440p panel, but not so bad that I care.

Hey, I have a few questions!

About the brightness, was it tested with a pure white background? My unit seemed to go up to 400-450 nits in SDR, but lose a lot if the image was all white on fullscreen.

About the input lag, did you guys test to see if there was any difference between DP and HDMI? Also, did HDMI allow for 12 bit 240Hz on this monitor?

About the HDR gamut being bad, have you guys tried manually increasing digital vibrance up to about 70% and see if it covers more of the gamut that way?

Hey,

We test using different window sizes, so the 2% window test is with white only covering 2% of the screen, and with the screen 100% white that’s where it gets really dim. That’s one of the known traits about this monitor is that the ABL is aggressive so full-screen windows are dim.

We only test the input lag over DisplayPort, but we expect the same results over HDMI. We didn’t officially test it to see if it accepts 12-bit 240Hz over HDMI, but it accepts 10-bit 240Hz, and theoretically it should accept 12-bit 240Hz as long as your graphics card supports compression.

We actually test the HDR color gamut with a 75% stimulus, so it doesn’t tone map well with bright colors. You can see this in the HDR Color Volume results as well. Decreasing it to 70% would likely result in some improved tone mapping, but this is the case with most displays as they tone map better with darker stimuli than brighter ones.

Let me know if you have any other questions :)

I’m surprised you didn’t mention in your review the CPC power saving feature that it’s impossible to turn off, as it drastically alters the brightness of this screen, as you can see in the two pictures I took with Brightness Stabilizer ON.

https://imgur.com/a/bPqMheH

Without the CPC I would agree with your review, but because of this I have to sell this monitor (I can’t return it as I live abroad).

This is something that you can’t access through the regular on-screen display, so unfortunately most people won’t be able to disable it. You’re right that it is something distracting, especially if you have the same screen on for a bit, but it can help reduce burn-in as well, as the screen doesn’t get as bright.

I have a follow-up question, edit: Changing FRL rate to 48GBps with CRU both in DSC and outside of DSC mode seems to work fine according to CRU. Is this a real change or CRU reporting it falsely?

Even if you change the bandwidth in CRU, because the ports are limited to 24 Gbps bandwidth, this doesn’t actually change anything and can cause problems with the signal.

The problem is that CPC is enabled even when I’m using Brightness Stabilizer ON. I mean, I’m not pushing any pixel beyond the 150 nits, so let me use the monitor without any anti burn in measure. It’s also really distracting in games as it makes white text and graphics looks light gray. Suddenly, the icons in games like FFXVI or Hogwarts Legacy are gray instead of white. This is not why I spent $1000. If I want so aggressive anti burn in measure I better just turn off the screen.

Did you test the input lag and response times on the sRGB picture mode? If not, which one did you use and would you expect the sRGB mode to be worse than the mode you did test? Does the “Game Mode” offer any benefits there?

We measured the input lag and response time in the ‘Standard’ picture mode, but we expect them to perform the same even in sRGB. It would be the same even in Game Mode, but it’s possible the image isn’t as accurate.

I noticed a new firmware was released (v103) does anyone know if it fixes the CPC issue?

Appears a firmware update was released a few days ago.

V103:

1. Upgrading brightness level to 200 nits after Brightness Stabilizer is ON.
2. Add Proximity Sensor ON/OFF switch in System Setting OSD page

Update: Tested the new firmware. The Brightness Stabilization setting is much better than it used to be at least. In fact, with a half or full white window it’s now substantially brighter than with it off in SDR/sRGB mode. That kind of irks me honestly, because I still like getting the poppy brightness in SDR content. Now I have to choose.

In HDR mode it appears to have made no changes to the brightness. The screen dims when you switch to HDR and dims further when you enable brightness stabilization.

Maybe this means Corsair are aware of the issue now.

Does it mean it can change the test results for SDR Brightness ? Does it need to be updated ?

Thank you for bringing this to our attention! We will create a retest for the monitor and we will update the review as soon as possible!

With the firmware update V103, the screen gets a bit brighter with Brightness Stabilizer compared to firmware V102, but it isn’t a significant difference either, and this doesn’t change the peak brightness with Brightness Stabilizer off.

The firmware isn’t advertised to fix the input lag, so we only retested the parts that the update was advertised to fix, namely the SDR and HDR peak brightness. That said, if Corsair releases a firmware that’s supposed to fix the input lag, we’ll retest it!

You let made a bad choice I bought corsair exneon 27QHD240 for my ps5 and I chose it from your recommendation in the best monitors for ps5 and you let 27QHD240 top number 1 and I realized that it has high input lag in 120HZ and 60HZ and I found LG has low input lag than corsair it you’re fault i am disappointed.

Hello,

Sorry that you feel disappointed, but as you can see in our Best Gaming Monitors For PS5 recommendation, we actually recommend the Samsung Odyssey Neo G8 as the best choice, and we don’t recommend the Corsair at all because of the increased input lag. If you do want one of the OLED monitors, the LG 27GR95QE-B would be the best choice though, because of its lower input lag.

New firmware V104 is out and the notes say “HDR function improvement.”

Any ideas what changed?

Version 1.04 “Improving Functionality and 33% Brightness Increase” Still looks a bit dim but my rooms stay dark so to me it looks amazing. It is definitely brighter though.

Hey everyone!

We’re aware that Corsair released a new firmware update, V104, that’s supposed to improve the Brightness. We looked into it, and unfortunately, it doesn’t significantly change the brightness in SDR or HDR. That’s the same case with the Corsair 45WQHD240, where the firmware update didn’t change the brightness either.

So I’m looking for a good OLED 27-inch screen, and right now I’m looking at both this monitor and the ASUS ROG Swift OLED PG27AQDM, and I’m leaning more towards the Corsair. The only things that I’m worried about are the ABL and the Gray Uniformity. I use Windows in dark mode and have most of my apps within dark mode, so ABL might not be too bad for me, but I’m worried about the Gray Uniformity, especially when I move windows around in dark mode if I’m going to notice a lot of vertical banding throughout the screen.

I’m wondering how the vertical banding has been for others, especially for those who use Windows dark mode and/or use a lot of apps in dark mode. I’m also going to mainly use the screen in SDR, and I normally don’t have my screens very bright, but I’m just worried about the ABL when closing or opening white windows.
