Asus ROG Zephyrus Duo GX651
Pros
Cons
The Asus ROG Zephyrus Duo GX651 is positioned as a high-end dual-screen laptop in the Zephyrus Duo line, built for demanding multitasking, creative work, and gaming. It combines an Intel Core Ultra X9 388H (Panther Lake) with an NVIDIA GeForce RTX 5090 Laptop GPU, plus 64 GB of fast DDR5 memory. A 16-inch 2880x1800 120 Hz OLED touchscreen anchors the experience, with the secondary display concept repeatedly praised in reviews for real workflow gains. Connectivity is extensive, including USB4/Thunderbolt 4, HDMI, SD card reader, Wi‑Fi 7, and Bluetooth 6.0, backed by a 90 Wh battery. Critics largely rate the concept highly but point to a very high price, portability compromises at 2.82 kg, and the removable keyboard being a weak link.

It’s expensive, but the Asus ZenBook Duo is a great little productivity machine. Its second display is extremely useful in creative work, even if it does come at the cost of a mediocre removable keyboard. I don’t know if I’d recommend this laptop to everyone, but for creative folks on the go, it’s one of the best laptops out there right now.

If you like to multi-task, but don't want the hassle of external monitors, this convertible laptop is one of the best options out there. You can enjoy two screens wherever you wander, while the ASUS Zenbook Duo 2026 is powerful enough to cope with 4K video editing and gaming. Creators are certainly well catered for by that Intel chipset and GPU. The screens themselves are stunners too. OLED tech that's bright, bold and pleasingly vibrant, with the ability to switch gamuts to match what you're up to. Video as well as photo editing and other creative tasks are a breeze on this thing. The ASUS Zenbook Duo is also a cracker for working on the move thanks to the excellent battery life, which stays strong even when using both displays!

I don’t want the Intel Core Ultra X9 388H to overshadow that this is a great dual-screen notebook that brings the idea of two panels on the go much more into the mainstream. The Zenbook Duo has gone through a thoughtful glow up, given two glorious OLED panels and ergonomic uplifts that make it a thoroughbred of a productivity machine. But Panther Lake is the key that brings all of this together nicely with a chip that provides both the horsepower and stamina to bring this back in line with what you’d expect from single-screen systems. Price aside, this is a belter.

This is a laptop, in my opinion, that has it all. For a relatively small penalty in weight and size, you get the most flexible machine it is possible to own. You can use it as a desktop productivity beast with two screens, or you can use it as a regular laptop with one. Either way, it performs brilliantly depending on what you want to do with it. It delivers great battery life, it’s quick, the screens are great, and the graphics performance from Intel’s latest iGPU is a revelation. Add impactful audio, great ergonomics and a decent webcam, and you have the most impressive mobile all-rounder I think I have ever reviewed.
