I have the Corsair Xeneon 27QHD240, which is fairly similar both in design and features. It's an overall phenomenal display, but worse than some of its direct competitors using the same LG panel (namely the ASUS PG27AQDM). Way overpriced in my opinion, but I made the debatable choice to go with the full Corsair theme for my setup.

Minor drawbacks to look out for:

• Subtle banding across the image (apparently a limitation of current OLED panels)
• Quite pronounced flicker if using VRR (G-Sync); worse of its class

This new one does NOT have the same panel, so none of what I just said probably applies, but I'd still be curious to compare the two to see if it's any better.

Sad to see that's still a thing with LG's WOLED panels even 5 years after I bought my B9.

Mind you this review is about a Samsung QD-OLED design, and it looks like they've come a long way in their old achiles heel (burn in). Bravo.

Thank you for reminding some of the risks of burn-ins in a static environment. I've gotten into endless discussions on this topic here, hopefully that will put the baby to rest for a while. However, you mention "if you're looking for a monitor solely for productivity, you might want to avoid OLEDs altogether."

Two questions about it:
- Is this screen a fourth generation, or another third one?
- If fringing isn't a concern, why avoiding this one? for the burn-ins risk? Or because it's not an issue unless you're looking at a VScode screen all day?

I'm not trying to nit-pick, I'm on the market for a wide curved screen for both coding and gaming, and unfortunately the mini-led I dream of doesn't seem to be in the pipe!

My plan is to get a 4K OLED when I upgrade my 4090 to a proper native 4K card and my current display develops undeniable burn-in, both of which I assume will happen around 5 years from now. We'll see how long a way they'll have come by then, or if they keep struggling with the same old problems.

"If you're looking for a monitor solely for productivity, you might want to avoid OLEDs altogether."

I've been using OLED panels both in my laptop and desktop PC for a while now, and I can tell you I've never been bothered by fringing at all. In my Corsair display it's noticeable in certain contexts, but not obvious enough to be annoying or distracting, even if you frequently work with text. Greatly blown out of proportion as an issue, in my opinion; I find the flickering while using VRR way more distracting, and it's rarely even discussed. As for burn-in, yes, you're gonna have it to some extent if you use the display as a daily driver, for long periods of time and with mostly static images (e.g. taskbars). That's just a bullet that you'll have to bite.

I don't like the power consumption. Especially with low nits.

Too many issues for 3 times the price. It's 2025 - burn in prevention for a display.
My calibrated proart monitor is according to the factory sheet below Delta e 1. I see here delta e over 7. I'm not so much in the monitor segment. I expect calibrated screens at a certain price point, regardless of the screen size. I expect several dedicated dp connectors in the form factor dp connector. I do expect a usb hub with 20gbps, not a 5gbps one. I do not want to see hdmi 2.1 but only dp 1.4 on a new monitor.

As I already mentioned earlier in the review Orbit is a feature that automatically shifts the image by one pixel per minute in a circular pattern while you're using the monitor. This is a way to fight against static UI elements. I usually find this feature distracting and undesirable, but I barely noticed it on the Corsair Xeneon 34WQHD240-C. Corsair found a good balance between how often the picture shifts, and by how much. There are also no issues with some Windows UI elements shifting away from sight, which I ran into on several previous occasions, for example, while testing the absurd INNOCN 48Q1V.

I'm not really sure why someone would choose this over the MSI MPG 341CQPX which uses the same panel, costs ~$750 and seems to have the same warranty period.

- Is this screen a fourth generation, or another third one?

Since this is a Samsung panel it's a second generation QD-OLED, but it does not share the new pixel layout of the non-ultrawide second generation OLED panels.

Corsair tax. Not worth it, unless you just really want to go with the brand.

Can this monitor select sRGB and then still adjust white point? My old Acer X27 (27" 4K 144Hz HDR IPS w/local dimming) could do that, but my brand new MSI MPG 322URX (32" 4K 240Hz QD-OLED) that I literally just got cannot. I like sRGB, but just slightly warmer than default. Also, unless I'm doing something wrong, OLED doesn't do bright HDR at all like IPS can.

Any chance 3440x1440 can be part of graphics card testing in the future? 4K is still to demanding, but 2560x1440 is so easily achieved that most cards should have plenty of power to run 3440x1440. It's a nice middle ground.

110 PPI + OLED Pentile = poor text quality. IMO, until OLED gets standard pixel structure, 4K - minimum resolution.
