LG UltraGear OLED 27 Gaming Monitor Review: Part Beauty, Part Beast
HDR, OLED’s naturally high contrast and a 240Hz refresh rate can make games look beautiful, but this monitor’s brightness behavior may make other tasks beastly.

LG’s UltraGear gaming monitors are some of the most popular models you can buy, so the $1,000, 240Hz 27-inch UltraGear 27GR95QE-B OLED HDR model sounded like one of the most interesting monitors to launch at CES this year. And it’s certainly interesting. OLED screens have the highest contrast you can find in a display thanks to their true blacks, and their naturally wide color gamut makes them excellent for TV screens.
But because monitors are used for so many different types of tasks, OLED’s strengths can occasionally become weaknesses and some of the technology’s inherent weaknesses, like brightness, need to be finessed. LG succeeds at gaming, for the most part, but doesn’t entirely succeed at all the other things the monitor needs to do when you’re not playing. There are some things that competing technologies like Quantum Dot OLED, found in monitors such as the Alienware 34 QD-OLED models, handle a bit better.
The UltraGear OLED 27 has a curved 45-inch sibling, the $1,700 45GR95QE-B. It has similar specs to the 27-inch model, with some similar complaints, but its low resolution for its size (3,440×1,440 pixels) means it’s not great for a lot of general uses despite its productivity-friendly dimensions.
Like
- Well constructed with good physical layout
- A ton of features
Don’t Like
- Some people don’t like the antiglare screen
- Can only access all the settings with the remote control
- Brightness performance issues
Design and features
The monitor’s physical design hits most of my checklist items for a «yay!» Easy to access ports: check. Easily maneuverable cable management: check. Solid build quality: check. A stand that allows the screen to pivot, swivel and adjust the height: check. Its only illumination is stripes wrapping around the electronics section the screen is mounted on, which may be too subtle for some people, but I like it. Plus, it looks like a gaming monitor without looking like every other gaming monitor.


The vents around the electronics section can be lit up.
Lori Grunin/CNETBut I hate that you can only access the full set of menu options via the remote. There are a few (like inputs) that you can get to using the hard-to-manipulate single joystick on the monitor and a few more that you can get to using LG’s OnScreen Control software, but a lot of the nitty gritty stuff — gamma and white balance choices, for example — requires the remote. And being able to maintain a slim profile with the skinny OLED screen means it’s got a huge AC adapter brick.

It has an extensive feature set as well. That includes all the basics for gaming, plus a full-range slider for the Black Stabilizer (a necessity for OLED), LG’s Dynamic Action Sync mode, which reduces latency between the system and the screen, and HDMI 2.1 for use with variable refresh-rate supporting Xbox Series X and S, and PS5.
But it’s got a ton of color and image-adjustment options that you rarely see in a gaming monitor, like 18 steps of manual white balance. The LG Calibration Studio is a full-featured profiling tool, complete with recalibration reminders, a host of predefined target spaces (including CIE RGB, Apple RGB, monochrome and a fully user-definable one) and the ability to save two of the custom profiles as hardware presets.


The ports are not only easily accessible, but they sit on either side of the stand so you don’t have to try to tilt or rotate it to accommodate hand contortions in order to plug something in.
Lori Grunin/CNETThe calibration software can be a bit glitchy, but it’s generally well designed. I’m a big fan of being able to set all the options on a single screen, and it’s pretty straightforward to understand and use. There’s one big thing I miss, though, and that’s the choice of calibrating for a full screen (as with most calibration software) rather than just within a 10% window. In the case of the LG, it’s critically important.
Performance
Basically, in SDR the screen can hit around 200 nits for any screen coverage except full screen. At that point, it seems like it drops to a maximum of around 150 nits. That’s why it seems so dim for most general use — because most of us work on full white screens. The perception of dimness isn’t helped by the excellent antiglare treatment, and a more matte finish makes it seem like it’s lower contrast as well, despite OLED’s effectively infinite contrast. People have complained that they wish the screen was more like the typical glossy TV OLED, which tends to look brighter with more saturated colors, but, well, I loathe glossy screens for the same reasons. I’m used to swimming upstream in life.
But it also screws up calibration, because LG’s software (and presumably its factory) calibrates over an area that has different brightness characteristics than full screen, which screws up the gamma calculations. You may not have any problems with gamma oddities and a lot of profile definitions (like sRGB) are based around low peak brightness, partly because they were defined for a time when monitors tended to peak at 200 or 250 nits. However if you’re, say, doing illustrations on a paper white background, it can mess things up and certainly makes color unpredictable.
SDR Color measurements
Preset | Gamut (% coverage) | White point | Gamma | Peak brightness | Accuracy (DE2K average/max) |
---|---|---|---|---|---|
Gamer 1 (default) | 97% P3 | 7,950K | 2.2 | 205 | 5.3/18.4 |
Gamer 1 (with manual white balance setting C1) | 97% P3 | 6,450K | 2.2 | 188 | 1.9/3.58 |
Gamer 2 | n/a | 6,900K | 1.2 | 206 | n/a |
FPS | n/a | 6,800K | 0.97 | 163 | n/a |
RTS | n/a | 6,500K | 0.83 | 139 | n/a |
sRGB | 96% sRGB | 6,150K | 1.6 | 110 | 4.06/8.17 |
Vivid | 97% P3 | 8,600K | 0.93 | 139 | 14.6/27.13 |
Custom calibration: Adobe RGB (75% window) | 90% Adobe RGB | 6,400K | 2.2 | 197 | 1.8/4.6 |
Custom calibration: Adobe RGB (full screen) | 90 % Adobe RGB | 6,400K | 1.2 | 170 (at 95% gray), 144 (white) | 5.7/12.1 |
That’s illustrated by the two Adobe RGB calibrations in the chart: I calibrated the monitor using LG Studio, with its 10% window, then measured the results with fractional and full-screen targets in Calman 2023. You can always use a third-party calibration utility to massage it to work, but those profiles can’t be saved as a monitor preset.
The brightness variability also results in odd results for the gaming presets which are further complicated by the Black Stabilizer settings. (OLED can render pure black, which is a case traditional gamma calculations was never meant to handle, so the ability to boost the brightness in shadow areas is essential for visibility.)
The shape of the gamma curve doesn’t really matter much for gaming; appropriate — rather than accurate — shadow detail, contrast, brightness and color matter a lot more (though game designers might disagree). DAS isn’t a pixel refresh booster (OLED is plenty fast at 1ms or less) or motion blur compensation feature so it really doesn’t affect brightness the way those can. And the 240Hz screen refresh is rock solid.
HDR mode measurements
Preset | White point | Full screen brightness (nits) | 10% window brightness (nits) |
---|---|---|---|
Gamer 1 | 6,350K | 146 | 642 |
Gamer 2 | 8,100K | 159 | 750 (peak 883 — 938 nits in 2% window) |
FPS | 8,750K | 145 | 709 |
RTS | 6,350K | 143 | 661 |
Vivid | 10,000K | 142 | 663 |
HDR looks great, and unlike a lot of HDR monitors this one lets you adjust settings like brightness and the gaming presets have settings for HDR along with SDR. In HDR it hits the full rated 98.5% P3 gamut coverage.
LG rates the display at a peak brightness of 800-1,000 nits for a 3% window, which it certainly hit. But it requires several seconds to ramp up to peak and can’t sustain it for more than a few. In practice, you’re more likely to see a maximum of about 700-750 nits consistently, which still looks great given the monitor’s price. The full-screen brightness is still low, but you’re far less likely to encounter situations where it matters.
If you can get away with spending $1,000 on a monitor that you’ll love for gaming but probably not so much for work, then the 27-inch LG UltraGear OLED will probably tickle your eyeballs. But if it needs to multitask while it takes up space on your desk, you may need to put a little more thought into the purchase.
Testing
All measurements are performed using Portrait Display’s Calman 2023 software using a Calibrite ColorChecker Display Plus (formerly X-Rite i1Display Pro Plus) and a Murideo Six-G pattern generator for HDR testing where necessary, or the Client3 HDR patterns within Calman, where possible. How extensive our testing is depends on the capabilities of the monitor, the screen and backlight technology used, and the judgment of the reviewer.

Google I/O Announcements: The Latest AI Upgrades Coming to Gemini, XR and More
From its new Project Aura XR glasses to Chrome’s wants-to-be-more-helpful AI mode, Gemini Live and new Flow generative video tool, Google puts AI everywhere.

As you’d expect, this year’s Google I/O developer’s conference focused almost exclusively on AI — where the company’s Gemini AI platform stands, where it’s going and how much it’s going to cost you now for its new AI Ultra subscription plan (spoiler: $250 per month). Meanwhile, a new Flow app expands the company’s video-generation toolset, and its Android XR glasses make their debut.
Plus, all AI usage and performance numbers are up! (Given that a new 42.5-exaflop Ironwood Tensor processing unit is coming to Google Cloud later this year, they’ll continue to rise.)
Google’s Project Aura, a developer kit for Android XR that includes new AR glasses from Xreal, is the company’s next step in the company’s roadmap toward glasses-based, AI-driven extended reality. CNET’s Scott Stein goes in-depth in an exclusive interview with Shahram Izadi, Google’s VP and GM for Android XR about that future. And headset-based Project Moohan, developed in conjunction with Samsung, is now available, and Google’s working with Samsung to extend beyond headsets.
For a play-by-play of the event, you can read the archive of our live blog.
Google already held a separate event for Android, where it launched Android 16, debuting its new Material 3 Expressive interface, updates to security and an update on Gemini integration and features.
A lot of the whizzy new AI features are only available via one of its subscription levels. AI Pro is just a rebranding of Google’s $20-per-month Gemini Advanced plan (adding some new features), but Google AI Ultra is a pricier new option — $250 per month, with half off the first three months for the moment — that provides access to the latest, spiffiest and least usage-limited of all its tools and models, as well as a prototype for managing AI agents and the 30 terabytes of storage you’re going to need to store it all. They’re both available today.
Google also wants to make your automation sound smarter with Personalized Smart Replies, which makes your generated answers sound more like you, as well as plowing through pieces of information on your device to provide relevant information. It’ll be in Gmail this summer for subscribers. Eventually, it’ll be everywhere.
Also, it includes lots of better models, better coding tools and other details on developer-friendly things you expect from a developer conference. The announcement included its conversational Gemini Live, formerly part of Project Astra, its interactive, agentic, voice AI, kitchen sink AI app. (As Managing Editor Patrick Holland says, «Astra is a rehearsal of features that, when they’re ready for the spotlight, get added to Gemini Live.») And for researchers, NotebookLM incorporates Gemini Live to improve its… everything.
It’s available now in the US.
Chrome AI Mode
People (that is, those over 18) who pony up for the subscriptions, plus users on the Chrome Beta, Dev and Canary tracks, will be able to try out the company’s expanded Gemini integration with Chrome — summary, research and agentic chat based on the contents of your screen, somewhat like Gemini Live does for phones (which, by the way, is available for free on Android and iOS as of today). But the Chrome version is more suited to the type of things you do at a computer rather than a phone. (Microsoft already does this with Copilot in its own Edge browser.)
Eventually, Google plans for Gemini in Chrome to be capable of synthesizing using multiple tabs and voice navigation.
The company is also expanding how you can interact with its AI Overviews in Google Search as part of AI Mode, with interactions with AI Overviews and more agentic shopping help. It’s a new tab with search, or on the search bar, and it’s available now. It includes deeper searches, Personal Context — which uses all the information it knows about you, and that’s a lot — to make suggestions and customize replies.
The company detailed its new AI Mode for shopping, which has an improved conversational shopping experience, a checkout that monitors for the best pricing, and an updated «try on» interface that lets you upload a photo of yourself rather than modeling it on a generic body.
Google plans to launch it soon, though the updated «try on» feature is now available in the US via Search Labs.
Google Beam
Formerly known as Project Starline, Google Beam is the updated version of the company’s 3D videoconferencing, now with AI. It uses a six-camera array to capture all angles of you, which the AI then stitches together, uses head tracking to follow your movements, and sends at up to 60 frames per second.
The platform uses a light field display that doesn’t require wearing any special equipment, but that technology also tends to be sensitive to off-angle viewing. HP is an old hand in the large-scale scanning biz, including 3D scanning, so the partnership with Google isn’t a big surprise.
Flow and other generative creative tools
Google Flow is a new tool that builds on Imagen 4 and Veo 3 to perform tasks like creating AI video clips and stitching them into longer sequences, or extending them, with a single prompt while keeping them consistent from scene to scene. It also provides editing tools like camera controls. It’s available as part of Gemini AI Ultra.
Imagen 4 image generation is more detailed, with improved tonality and better text and typography. And it’s faster. Meanwhile, Veo 3, also available today, has a better understanding of physics and native audio generation — sound effects, background sounds and dialogue.
Of course, all this is available under the AI Pro plan. Google’s Synth ID gen AI detection tool is also available today.

WWDC 2025 Set for June 9. What to Expect From iOS 19 and How to Watch
The tech giant has published the lineup for its summer software event, including details of how to stream the keynote.

Apple has revealed the lineup for this year’s WWDC, its annual developer conference, which is scheduled to take place from June 9 to June 13, with a mix of online and in-person sessions. The company has scheduled a special event for the first day at Apple Park, where it will stream its keynote and platforms state of the union address.
The June 9 keynote is scheduled to take place at 10 a.m. PT, and will detail «groundbreaking updates coming to Apple platforms,» according to a press release. During the keynote, we expect to see the company announce its plans for iOS 19 and other software updates across iPad, Mac, Apple Watch and Apple TV.
The platforms state of the union will take place on the same day at 1 p.m. PT, offering «a deeper dive into the new tools that will further empower Apple developers, including advances across iOS, iPadOS, macOS, tvOS, visionOS, and watchOS.»
You can watch both events online via apple.com, the Apple TV app, and the Apple YouTube channel.
As always, iOS 19 likely won’t arrive later in the year (probably after the annual September iPhone event), but WWDC will provide us with our first glimpse of Apple’s plans for our devices. In the meantime, check out our iOS 19 wish list of features that CNET staff hope will be coming with this next big software update.
What is WWDC?
WWDC is a conference for the developers who create the apps we use across our Apple devices, from our iPhones to our MacBooks, to learn about new tools and features they can take advantage of that year. However, the event also garners significant attention from beyond the developer community, since it tells us all we need to know about what to expect from the next generation of software updates that will come to our devices.
The online event is free to attend for all developers, and anyone who is curious can tune into Apple’s keynote. But those who want to attend the June 9 event at Apple Park in person need to apply online. In the days following, students and developers will attend sessions where they can engage more deeply with the changes to Apple’s platforms, which will allow them to ensure their apps are fully compatible with and that they take advantage of those changes.
«We’re excited to mark another incredible year of WWDC with our global developer community,» said Susan Prescott, Apple’s vice president of worldwide developer relations. «We can’t wait to share the latest tools and technologies that will empower developers and help them continue to innovate.»
What to Expect at WWDC 2025
If rumors are to be believed, Apple’s operating systems are set for a dramatic design overhaul this year. According to Bloomberg, iOS 19, iPadOS 19 and MacOS 16 will all feature new icons and menus, which will also change how our devices and controlled and navigated. The aim is reportedly to create a more cohesive style across platforms that will be reminiscent of VisionOS, the operating system designed for the company’s mixed-reality headset.
But that’s not all — Apple will likely use WWDC to outline the progress its made in the field of AI. «I’m looking forward to seeing more details about Apple Intelligence and the new features that will become available,» said Francisco Jeronimo, VP of devices at IDC. «This is critical for Apple, as Google Gemini and the Android vendors have taken significant steps forward with their AI offerings.»
Last year at WWDC 2024, Apple announced iOS 18 and Apple Intelligence — as well as updates to Siri that have yet to materialize.
