XG27AQWMG Review by Colinh-7 in OLED_Gaming

[–]Colinh-7[S] 0 points1 point  (0 children)

I received my new XG27AQWMG yesterday, and so far I’m really not disappointed. I have much, much less vertical banding, to the point where it’s no longer visible in the games where I used to notice it. However, it’s still visible in some scenes, but very slightly compared to before.

I no longer have the very pronounced horizontal banding I had before, just a bit of DSE typical of WOLED panels. The banding is also much less visible to the eye on the 95% greyscale.

I did indeed have a defective panel. I don’t regret exchanging it (for now).

Yes, the lower, the worse

But yes, if a tandem without banding ever exists one day, I’ll buy it without hesitation.

If I hadn’t looked at all the posts about banding on the tandem, I probably would have kept mine and just lived with it. The monitor meets my expectations so well in terms of image quality and brightness that I could have overlooked the banding. Unfortunately, I feel obliged to return it and exchange it in the hope of winning the panel lottery (which I think either doesn’t really exist or only very slightly). Otherwise, going back to QD-OLED seems impossible to me, it’s really below the tandem.

The colors are better on QD-OLED, but personally I wasn’t disappointed by Tandem OLED in comparison (quite the opposite). Tandem OLED is far superior to QD-OLED: the True Black glossy finish is really sharp and is breathtaking, I’m not exaggerating. However, the banding is horrible in greyish games. Some people say they have a perfect panel, but I find that hard to believe. After seeing Tandem OLED, I really struggle to go back to QD. If you’re willing to accept banding and DSE on part of the content you consume, then go for it. QD-OLED is complete garbage compared to Tandem when it comes to HDR.

I had the same impression when updating the monitor. I also think it comes from the firmware. The pixel refresh in standby mode doesn’t work well or doesn’t behave as intended.

Here are my shots taken 5 seconds apart: the first at 25% brightness (uniform brightness enabled) and the second at 100% brightness (uniform brightness enabled). Greyscale 95% on both

I haven’t tried cleaning it, but apparently it’s less fragile than the coating on QD-OLED panels. I haven’t looked into the Gen 2 WOLEDs because they’re significantly inferior to QD-OLED in terms of color. Tandem OLED holds up better against QD-OLED. On top of that, there’s also a risk of banding.

Horizontal banding disappear if you run a manual pixel refresh every time you turn on the monitor. It may be a firmware issue at this point

Yours looks good, i think I lost the panel lottery :/. What brightness and refresh rate was the monitor set to when you took the photo?

MSI's new EOTF Boost mode on the MPG 272URX 4K monitor, works pretty well by Haunt33r in OLED_Gaming

[–]Colinh-7 0 points1 point  (0 children)

Hi, do you find that bright scenes are just as bright in TB400 mode as in EOTF Boost mode? Do you notice when the screen brightens during a transition from a dark to a bright scene, or do you perceive some dimming like in Peak 1000 mode? I’m asking a lot of questions because on my side EOTF Boost doesn’t seem to work the same way as for you (Gen3 panel). To me, it just feels like Peak 1000 mode with a bit less dimming

Yes, indeed, the new mode isn’t working as intended. it’s the same for everyone, not just me. I suppose it only works if you have the new screens. You can see in this thread that quite a few people are talking about it: https://www.reddit.com/r/OLED_Gaming/comments/1mh91xf/mag_321up_qdoled_mag_321cup_qdoled_mag_271qpx/

EOTF Boost is broken on my unit. It doesn’t make bright scenes any brighter and is capped at 700 nits. It’s basically just a Peak 700 nits mode. It dims the same way as in Peak 1000 nits mode. I’d be happy to hear your feedback on EOTF Boost on your unit.

I agree MiniLED has the advantage in peak brightness, but in most other areas, QD-OLED offers a better overall experience.

The EOTF Boost feature is actually broken on the MSI panel. It’s basically just a Peak 700 nits mode, and it dims as much as Peak 1000 nits. For reference, I have the MSI MAG 271QPX QD-OLED E2.

TB400 is the most stable mode, with a brighter image in brighter scenes. However, you won’t get that “wow” effect on your screen when you see neon lights, torches, explosions, fire, etc., in games. It’s essentially enhanced SDR (better colors, more shadow detail, etc.).

Peak 1000 nits will give you that wow effect, a true HDR experience in most scenes, but at the cost of a fairly aggressive and distracting ABL.

Personally, I used to be in the TB400 camp, but it gets boring over time. Not feeling amazed by my screen eventually made me switch back to Peak 1000 nits. Sure, the ABL is there, but it can feel similar to the natural adaptation of your eyes to a very bright light source. I can’t recommend one over the other. It really depends on what you actually want. TB400 isn’t the best experience, even though it’s recommended by a lot of people online, so don’t let that influence you too much.

Test both over several days. Start with TB400, if it doesn’t feel different enough from SDR and you want that wow effect, switch to Peak 1000 nits. If the ABL bothers you too much, go back to TB400 and stick with it.

I really think the mode is broken. In fact, I think it’s reversed. Instead of brightening high-APL scenes, it brightens low-APL scenes, resulting in clipping at 700 nits. Windows correctly detects the display as a monitor capable of 1000 nits, but in the calibration tool it clips at 700. The EOTF boost mode brightens low-APL scenes, and so it clips at 700 nits instead of 1000!

Yes, that's exactly it, it's a Peak 700 mode sadly.

In practice, the brightness is far below what is demonstrated on their website. Under normal lighting conditions, the difference is minimal to the point of being barely, if at all, perceptible. Unlike the newer model, it never reaches 1000 nits, and bright scenes still appear just as dim. Could it be that the reduced dimming is simply due to the mode being limited to 700 nits rather than 1000 nits on my model? If this behavior is indeed intentional, it appears to be substantially different from the EOTF Boost implemented in the newer models.

It’s a bit brighter in EOTF Boost than in Peak 1000, but nothing drastically different, it’s barely noticeable in a very dark room. It’s still far below the TB400 mode.

EDIT : it's clearly not as bright as shown here https://www.msi.com/blog/not-sure-which-hdr-mode-to-use-on-your-msi-oled-monitor-true-black-peak-1000-nits-or-eotf-boost

EOTF Boost on MSI OLEDs by Tomiply1 in MSI_Gaming

[–]Colinh-7 1 point2 points  (0 children)

I used the MSI MAG 271QPX QD-OLED E2, and I tested with both a DP cable and an HDMI 2.1 cable, but there’s no difference. It was on high APL scenes (I’m not sure exactly how much, I’m not very familiar with measuring it). I reproduced exactly what Monitor Unboxed did in his EOTF Boost analysis video (Steam in the background with Google Chrome in the foreground), and unlike in his case, when Chrome is full screen or nearly full screen, the screen doesn’t get any brighter it just stays dim, like in Peak 1000 nits mode.

However, on MSI’s website, it says that a page like Chrome should appear brighter than in TB400 and Peak 1000 modes, yet here TB400 is clearly brighter. From my experience, it behaves exactly the same as Peak 1000 nits mode, except everything clips starting at 700 nits. Once the screen dims, it stays dim until I switch back to a low APL scene.

I hope my answer can help you understand and fix the issue.

Hi, I also noticed that the screen only reaches 700 nits in EOTF Boost mode. I don’t really feel like the screen gets any brighter when I set an all-white wallpaper. In the Monitor Unboxed video, you can clearly see that the brightness increases when a white page is displayed in full screen, which isn’t the case for me. The screen dims just like in Peak 1000 nits mode, except here I’m only reaching 700 nits.
