Dell just announced its first Copilot+ mini PC running on Intel's Core Ultra Series 3 chips, and I'm in love with its customizable port selection that unlocks up to five external displays with a mix of 4K and 5K resolutions.

Battery life has been one of the laptop industry’s most persistent design headaches, especially among Windows notebooks. Despite significant gains in chip efficiency, the display consistently ranks among the biggest power consumers in any portable computer. Most laptop screens refresh at a fixed rate regardless of what’s actually on them, which means the panel keeps drawing full power even when you’re sitting completely still, reading a document with nothing on screen changing at all.

LG Display’s new Oxide 1Hz panel is the first mass-produced LCD laptop screen that doesn’t work that way. Rather than holding a fixed rate, it reads what’s on screen and drops to 1 Hz when the content is static, then scales back up to 120 Hz for video or gaming. LG began mass production on March 22, 2026, claiming the first-ever achievement of this at scale.

Designer: LG, Dell

The technology relies on custom circuit algorithms and a new oxide material applied to the panel’s thin-film transistor. That oxide holds an electric charge longer than conventional LCD materials, letting the screen maintain a still image without continuously refreshing it. LG claims the result is up to 48% more use on a single charge versus existing solutions, which is a significant number if it holds up in everyday use.

In practice, this matters most during the parts of a workday you spend the bulk of your time in. Checking emails, reading through documents, and sitting on a static slide during a meeting are all moments where a 60 Hz or 120 Hz screen burns power for no real benefit. The Oxide 1Hz panel handles those scenarios at a fraction of the usual draw without any visible difference.

When you do pull up a video or launch something that demands smooth motion, the panel doesn’t hesitate. It detects the change and jumps back up to 120 Hz automatically. There’s no mode to switch into, no setting to toggle, and no trade-off to manage. It just adjusts based on what’s happening on screen, which is how this kind of feature should work in the first place.

The first laptops to ship with this panel are the Dell XPS 14 and Dell XPS 16 for 2026, both unveiled at CES 2026 in January. The LCD option on both models runs at 1920 x 1200 pixels and 500 nits of brightness. Dell’s OLED option only drops as low as 20 Hz, which means the more affordable LCD configuration actually wins on low-power behavior.

Here’s where it gets interesting from a design standpoint. The display is one of the biggest power consumers in any laptop, so a screen drawing significantly less power during typical use creates real headroom for designers. They can use that headroom to maintain battery size and gain extra runtime, or to trim the battery slightly for a lighter, thinner chassis without giving up the battery life buyers already expect.

Of course, LG is already planning a 1 Hz OLED version of this technology for 2027, which is when things could get more interesting. OLED handles contrast and color in ways LCD can’t match, and pairing that quality with proper low-refresh-rate behavior could push portable laptop design further than it’s been able to go. For now, the Oxide 1Hz LCD is in something you can actually go out and buy.

Stop waiting for 2026's laptop prices to stabilize. This Dell XPS 13 deal is the perfect hedge against rising costs, offering OLED luxury for a mid-range price.

The Dell portfolio of laptops and other devices can be overwhelming, even after a simplifying rebrand. Here's what you need to know to pick the best Dell for you.

Dell's 14 Plus is perhaps a bit too expensive at the regular $1,000 price, but the decision to cut the cost in half for a limited time just seems like overkill. Here's why I think this is the laptop deal to beat.

J’adore ces histoires de bidouille légale qui montrent à quel point les ingénieurs peuvent être créatifs quand il s’agit de contourner certaines limitations. Et celle que je vais vous raconter aujourd’hui, c’est du grand art, vous allez voir.

Ce n’est pas quelque chose de récent mais plutôt une astuce géniale qui date d’une époque où les fabricants de PC comme Dell savaient “transformer” des versions d’essai en logiciels complets, et tout ça parfaitement légalement !

I reviewed the Alienware 16 Area-51 AW30 gaming laptop. It's absolutely blown me away with its smooth performance, colorful RGB, and mechanical keyboard.
