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.

To read about our monitor tests in-depth, please check out Display Testing Explained: How We Test PC Monitors. We cover brightness and contrast testing on page two.

Uncalibrated – Maximum Backlight Level

The Flex varies its brightness depending on the average luminance of the image. That means a full white field will measure around 180 nits. As the window gets smaller, the brightness goes up. I measured a 25% window to get 437 nits. At 3%, the Flex tops 1,000 nits.

Since the black level can’t be measured, OLED contrast is theoretically infinite. The G8 has a zone-dimming backlight that can’t be turned off, hence its high contrast score.

After Calibration to 200 nits

Deciding on a peak output level for the Flex required some trial and error. On the maximum setting, a full field was only 180 nits, as I stated earlier. Setting a 25% window to 200 nits made the image too dark. My room is sunlit, so I can run high brightness without visual fatigue. I eventually settled on the maximum brightness setting as my preference. Your mileage will vary depending on your viewing environment.

With unmeasurable black levels still in play, the Flex’s static and ANSI contrast ratios cannot be determined.

    We can pick flat or curved and save 50%... I don't get the niche for this product other than, "Look at my monitor, it has two arbitrary modes of rest."

    As an earlier adopter of 1440p at 165hz I paid nearly 600 dollars for it, but this is not a apples to apples comparison, because our monitors are likely substantially different when it comes to response time, perceived blur, brightness, and features.

    Who is this for? I cant think of a use case for such a feature... I've never sat in front of my curved display and thought to my self "man, I wish I could bend this."

    The main reason for this feature could be "lower shipping cost". Instead of making an extra $300 on the curved monitor, the supplier can make $305 extra. It's not a big deal now, but is will be when the price drops to $199.

    Some users may enjoy the option to switch between flat for work and curved for gaming. Additionally, there may be the argument that for a movie night with several persons, a flat screen is a bit better for the persons sitting on the sides of the couch. And there also is the issue that when someone has a multiple display wall-setup, a curved display may not be that great to have as a side display - and having a display with some flexibility about where it can be used in such a setup, that may be appealing.

    Not saying that it would be enough of an argument for me personally to spend that much on it. Just naming some examples of what some may find quite nice about it.

    I was about to do backflips when it said that it had low pixel density (something like 2560 X 1080 or 2560 x 1200), but alas, that's way too high for mortals.

    I think it might be priced for the target audience, people who can just buy a top of the line GPU, or someone making content for both flat and curved displays, to quickly test them, though I don't know how much it might last doing that constantly.

    That's a lot of money, for a silly marketing gimmick.
