LG’s next-gen 120Hz display promises a huge jump in laptop battery life

Your screen no longer needs to waste power when you are staring at your inbox.

LG Display has begun mass production of a new LCD laptop panel featuring Oxide 1Hz technology, which automatically adjusts the refresh rate between 1Hz and 120Hz based on on-screen activity. This technology is being mass-produced for the first time in laptops, and the battery life gains are genuinely impressive.

But we have had a 120Hz refresh rate display for a long time, so how can it be the first time, you might ask? Well, not all 120Hz displays are the same. Most laptop displays dynamically refresh the screen somewhere between 25Hz and 120Hz, depending on the content being displayed.

This LG panel can drop down to 1Hz when your screen is mostly still, like when you are reading emails or going through a research paper, and ramp up to 120Hz when you are watching a sports event or playing a game.

Why does the 1Hz refresh rate even matter?

Refresh rate refers to the number of times your screen redraws itself per second. A higher refresh rate produces smoother visuals, making it ideal for fast-moving content.

The problem is that most laptop screens run at high refresh rates all the time, or cannot refresh down to a low enough number that can have a meaningful impact on the battery life, even when nothing on the screen is moving. That is wasted power, and your battery pays for it.

LG Display developed its own circuit algorithms and new materials to make the low-power mode actually work. The result is a 48% improvement in battery life compared to existing solutions. That is a vast improvement that will extend your laptop’s battery life.

Who gets it first?

LG Display is first supplying these panels to Dell for its premium XPS lineup. Dell has already shown off new XPS models using this panel at CES 2026 back in January. LG Display is also planning a 1Hz OLED version using the same technology, set to begin mass production in 2027.

Deepfake bosses are crashing video calls, and researchers are trying to expose them

Seeing your boss on video no longer proves they are real

Researchers at Fraunhofer SIT are fighting against deepfake meeting video calls

Entering into a meeting with your boss and several familiar coworkers inside a video conference is the next area vulnerable to cybercrimes, and it's all because of deepfake technology. Researchers at the Fraunhofer Institute for Secure Information Technology SIT are working on a real-time warning system designed to identify attempted fraud during corporate video conferences.

The report states that criminals are increasingly targeting video meetings for identity theft and financial scams, taking advantage of the trust people place in familiar faces and voices. The intention is to flag suspicious activity while the meeting is still taking place. This gives an employee a chance to stop before following an expensive instruction from an AI-generated executive.

Apple will finally stop making iPhone-to-Windows copy-paste such a chore

Your iPhone may finally copy and paste with a Windows PC like it should

Apple Universal Clipboard feature

Copying something on an iPhone and pasting it onto a Windows PC should be one of the least remarkable features imaginable. While this simple process seems effortless between an iPhone and Mac, Windows users are still left waiting.

Now, Microsoft is formally asking Apple to provide interoperable clipboard access through the company’s European Union interoperability process. The request, submitted on March 25, argues that iOS restrictions prevent third-party platforms from creating an experience comparable to Apple’s Universal Clipboard. Apple has now reached Phase III and committed to developing a solution.

Chrome wants more extension reviews, but good ratings won’t keep malware out

Google is testing built-in extension review prompts, but good ratings can still hide malware

Google is preparing to add extension review links directly inside Chrome, putting feedback closer to the menus people already use to manage their add-ons.

A Chromium change, first spotted by Windows Report, points to review options in the Extensions menu, the chrome://extensions management page, and extension context menus. Only eligible Chrome Web Store extensions in good standing would qualify, and the feature is still under development.
