The 240Hz refresh feels like a future-proofing, especially with this new generation of Nvidia and AMD GPUs just hitting the market. 1440p has long been the sweet spot for PC gaming; while 240Hz and 360Hz 1440p monitors do exist, this is our first time seeing 240Hz 1440p on an OLED panel. Given how great the OLED panel looks, the UltraGear OLED 27 makes a very strong argument that more resolution isn’t always better. And paired with the high refresh rate, it looks fantastic.
That’s annoying, but it’s an easy problem to solve. What the UltraGear OLED 27 gets right is adjustment. Ironically, you don’tneed a screwdriver to set up the sturdy stand, and it enables just shy of four-and-a-half inches of height adjustment, 20 degrees of swivel, 20 degrees of tilt, and the ability to turn the monitor vertically.

Keep in mind that the calibration will only be as good as the device you’re using, but the same could be said for software profiling anyway. There’s no options in the software to use a “correction matrix” or to profile your meter against a reference device, so the accuracy might not be as good as software where that’s possible – like Calman Ultimate for instance which includes a correction matrix for WOLED panels. However, this is free software from LG, and the results will be better and more practical than software profiling, so it’s great to see it included. You can of course calibrate the other preset mode to different targets if you want. It’s a shame there’s no calibration support for HDR though. Brightness and Contrast OLED panels aren't known for their brightness compared to other panel types, but this is low for an OLED, where the average sits around 250-300 nits. For example, the Alienware 34 OLED monitor does about 250 nits, and it's by far the best OLED gaming monitor on the market at the moment. It does get a little brighter if you switch to reader mode, which makes sense since reading text on a screen with low brightness can strain the eyes.
Class 3)A lag of more than 16.66ms – the equivalent of more than 2 frames at a refresh rate of 120Hz – Some noticeable lag in daily usage, not suitable for high end gaming You’re meant to control the monitor with the included remote, but even with that, the UltraGear OLED 27 runs into issues. For starters, the battery slot on the remote requires a screwdriver to get open, and LG doesn’t include the coin battery you need to power the remote. This wouldn’t be a problem if you could control the on-screen display with the button on the monitor, or if LG had included the battery, which very few people are likely to have laying around, but neither of those things are true. Jacob Roach / Digital Trends Regardless, these issues will happen over hundreds and hundreds of hours of playing the same kind of content, so don’t worry about it too much…just a little. The colour space of the screen was quite a lot wider than the sRGB reference (used for SDR content) and we measured a 126.2% relative coverage. There was over-coverage of sRGB in red and green shades, causing those to look more neon and vivid than intended. As normal with any wide gamut screen, measuring the accuracy of sRGB colours results in high dE errors, with an average of 5.0 and a maximum of 11.9. This is further exacerbated by the overly cool colour temp leaving a poorer colour accuracy than might otherwise have been offered if it had been closer to our 6500K target. Out of the box at these default settings, the screen is really not accurate for sRGB / SDR content. But via the remote control, the main menu has a reasonable range of options to play with. There’s a wide range of preset modes you can select from and customise, including two hardware calibrated modes if you have a compatible calibration device.Gradient handling was good though with no visible banding issues, and only minor gradation in darker tones. sRGB Emulation Mode As discussed in our detailed article about Response Time Testing – Pitfalls, Improvements and Updating Our Methodologywe are using an improved and more accurate method for capturing G2G response times and overshoot, based on figures that are more reflective to what you see visually on the screen in real-World usage. Our article linked above talks through why this is better and how we arrived at this improved method in much more detail.
