Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.
Our HDR benchmarking uses Portrait Displays’ Calman software. To learn about our HDR testing, see our breakdown of how we test PC monitors.
HDR is what OLEDs do best. Their naturally infinite dynamic range is a real asset. The 27QHD240 delivers typical performance for the category.
HDR Brightness and Contrast
Corsair claims 1,000 nits for the 27QHD240 when measuring a 3% window pattern. I cannot replicate this, but I measured a 25% window at over 800 nits, so I have no doubt as to this monitor’s capabilities. The Flex and the 27-inch Asus are a tad brighter, but there is no discernible difference when viewing actual content. The bottom three monitors are a bit dimmer overall but still deliver tons of depth and color saturation. Of course, all the panels have infinite HDR contrast thanks to their unmeasurable black levels.
Grayscale, EOTF and Color
The 27QHD240’s superb color accuracy extends to its HDR grayscale tracking, which is without visual error. There is a slight rise in blue levels as the image brightens, but this does not adversely affect the image. The EOTF tracks close to the reference line except for its slightly early transition to tone-mapping, which is a minor issue.
Color tracking is slightly off the mark at the inner saturation points though it gets closer to targets as saturation increases. Secondary colors are off hue as well. Magenta and cyan are a bit cooler than they should be and yellows have a slight green tint. In content, it’s at the level where the viewer can sense that something’s not quite perfect but can’t tell exactly what. Some tweaking of the 27QHD240’s firmware could resolve this though I cannot call myself dissatisfied, and I doubt any users will complain. Contrast and color saturation are so good that they mitigate these measured errors.

cknobman Its crazy to think there is a large enough market for a $1000 27 inch monitor to justify products like this.Reply -
hotaru.hino Is the subpixel layout different enough in a way that it produces something off about the image? e.g., like the color fringing on the QD-OLED displays.Reply -

There is. I personally don't have space for a 32" monitor. So 27" monitors are still a thing for me; although I have yet to see a killer 4k mini-led monitor in this size. I will say I wouldn't spend $1000 on a QHD OLED though. Resolution seems low and burn-in risk seems high.cknobman said:Its crazy to think there is a large enough market for a $1000 27 inch monitor to justify products like this. -

Eve / Dough is working on one as well. What is bothering you? The price?Kridian said:Who in the hell's buying these? Corsair, you've lost your mind. -

I'm waiting for the $700 27" oled. Maybe something with 144hz or something? I don't know if 240 is baseline for these panels. Seems like once someone besides LG makes oled gaming panels I'll be in luck.cknobman said:Its crazy to think there is a large enough market for a $1000 27 inch monitor to justify products like this. -

I'm in the market for a new monitor, and while $1k is more than I want to spend, I'd probably buy one if it were perfect.cknobman said:Its crazy to think there is a large enough market for a $1000 27 inch monitor to justify products like this.
One of the main things putting me off this generation is what I've read elsewhere about the subpixel layout being suboptimal for text. Also, I wouldn't mind getting a couple years' longevity data, to know whether burn-in is still a real issue.
So, instead, I think I'll probably opt for a conventional LCD monitor.

I'm leaning hard towards Asus XG27AQMR, but perhaps I could go with Dell AW2723DF. In either case, I think they're currently a little overpriced, so it'll take one of them getting discounted for me to pull the trigger. -

Just as crazy as to buy a $3000 gaming GPU.
