So even though this is last generation's model, it is still an excellent computer. The beauty is that it is seemlessly dual screen, but only when you need it. When you want to use it as a traditional laptop, it looks and feels just like a traditional laptop. But when you need the extra screen real estate, just slip the detachable keyboard off and it automatically and very quickly turns the 2nd screen on and you have twice the pixels to do your work. The laptop is plenty fast for most jobs. You're not going to play AAA games, but this is not a gaming laptop (ASUS actually now has a gaming laptop with this basic design, if Gaming/AI/content creation is your thing). I bought this for my parents, and they love it. It is small and compact, light and the battery lasts quite a while. It has good features, and for office stuff, streaming, web browsing, video conferencing and the like, it is a very useful and unique laptop. Highly recommend it. The only minor gripe, and one that doesn't really have a good solution, is the keyboard is a bit thin and flimsy when separated out for 2-screen work. But that's a minor complaint, and you can always buy a good keyboard if you really need one.

After a few months working with this amazing piece of hardware, there are a few minor glitches here and there but overall this is an incredible work horse that massively ups your productivity. I'm someone that has carried around a 2nd screen for years finding productivity increases significantly with a second screen. Now, being able to easily set up a 2-display scenario and code is just a dream come true. This machine makes me want to code, makes me want to work. Or if I'm in off work mode and just want to read reddit in one screen and watch football in the other, that's perfect too. There are a few minor hickups here and there but overall worlds better than any macbook or surface on the market, this is THE machine. --- previous review below --- Haven't found anything really to dislike yet (other than Windows 11 lol, 10 is superior). Was wondering how the build quality would be on the first go of a design like this, and so far it seems good. Stand is sturdy, I can prop it up even on my bed. In laptop mode (one screen) it's a little thicker than the single-screen Zenbooks from the last few years. Screens are pretty and very vibrant. Overall another great product from Asus. Why anyone would buy a Lenovo or HP I will never understand. edit: Install "Explorer patcher" for windows 11 to get the superior windows 10 start menu. Rear hinge is fantastic, much stronger and wider than expected. Dual screen mode will even prop up on a bed. Pleasantly surprised.

I've expected this form factor for a while now. I saw the writing on the wall 10 years ago and I understood why they couldn't exist then. I was really wondering how the touchscreen keyboard was going to play out when these dual screens start coming to the mainstream and Asus solved that issue entirely on the first try. In order to make the products we dream of we have to work around the battery limitations and up till about 3 years ago, this concept just wasn't possible without making it very thick and heavy. The advancements made in power management have been significant and Intel now offers a powerful 9 Ultra SoC that sips battery usage. I review laptops that are sent to me all the time (not for Amazon) and some have cutting-edge tech but nothing like the Asus UX8406. Asus gets so much right that it is hard to find a fault in anything. They have covered just about every little thing that you could complain about. Since I mentioned the keyboard first, lets start with that. The typing experience is probably the best I have ever tried. You truly sacrifice nothing. The key travel, backlighting, and terrific touchpad that supports gestures all come together to make for an amazing input experience. When disconnected from the laptop, you can burn through the keyboard battery in 45 minutes if you use the backlight heavily. Asus thought of that scenario already and offers a USB C charge port built-in on the side of the keyboard. So if you need to have backlight, you can. The dual 3K 120 MHz displays look as good as you would expect they would. I would easily say that they have no equal as far as laptop displays go. You can crank up the resolution and use Windows zoom to about 150% and get excellent results. On to the new Intel Arc 8 core graphics chip. This thing games! GTAV, Forza 5 Horizon (at the highest resolution), and Ultimate Spiderman are all I've tested but I came away shocked. Its really good. I didn't buy it for games but it's a huge bonus! The Intel 9Ultra and 32GB RAM mean that I'm never waiting for this laptop. It is as fast as you are at commanding it. I have had very few hiccups in performance and since the last BIOS update, I have had zero. My use case is remote IT support and Adobe CC 2024 apps and it handles both exceptionally. Before this laptop, I was using a Surface Studio Laptop 2 and I swear that thing (still under warranty) seems like a relic now. I'm sure that you have your use case in mind if you're shopping for this laptop so I wont gush about the dual screen utility. You probably are like me and are used to carrying a USB monitor or two to create the extra real estate needed for enhanced workflow. Desktop Mode is my go to. There is some decent utility is the included My Asus app and I was surprised how well it worked. RAM dumping. Push one GUI button and dump your RAM. I know you can do this in a command prompt but Asus has this tool and a lot more in the My Asus app. I normally don't give the include manufacturer system app any usage other than driver updates but Asus has something here. To sum it up, I welcome this new category of laptop and look forward to the innovation that will come from this pioneering product. It's great to see a company (or two) breathe some excitement into a market that was all too complacent for way too long.

This laptop was so perfect for working remotely away from my main home office since you had two screen for multi-viewing while tasking. The screens are gorgeous, processor snappy and the detachable keyboard inspired. Sound is "meh" but you should never expect much from a laptop. Everything was great until working one day I hear a "pop" then proceed to see a crack marching across from the side center of the screen. Everything still worked but that crack was crazy and kept growing when the screen stayed on. So, I shut it down and reached out the ASUS support. They were great at the first contact and, given that it was only one month old, fully under warranty for repair. All I had to do was send it in which you have to pay for...not cool thing #1. Not cool thing #2 was that I chose the expensive option to return with next day shipping to make sure I could get it back in the 7-10 day window they quoted. I also paid for next day shipping for returning. $170 bucks in expedited shipping costs later, I handed the beloved laptop over to FedEx for quick delivery. I log in to FedEx the next day and realize that ASUS gave me a GROUND label even though I paid for expedited! So, 6 full days later the laptop showed checked in at the repair center. So, back to ASUS support I go only to find that they had the wrong shipping number and kept telling me that my laptop had not left Seattle. I even uploaded proof with their person's initials for accepting the return. Three days later I chat back with ASUS support and they still have not logged in the laptop which has officially been in their hands for 4 days! Eventually they found it and here I sit still waiting for any word on when I will get it back. Also, no offer to refund my $170 bucks for the expedited shipping I did not receive. So, buyer beware...it's a great device until it does not work and like me, you will be up a creek without a paddle waiting to hear that your laptop is repaired and heading back to you...hopefully with the expedited shipping that you paid extra for. Not holding my breath on that one. So great laptop until it breaks then awful customer service.

I had a specific need for multiple touch monitors in a portable fashion (for a theatrical lighting control console), so the timing of this release was perfect. Starting with the cost, there's a lot of value here relative to other machines. For $200 over the base model, you get the faster CPU, twice the RAM and the higher resolution screens. TWO screens. First off, as a typical laptop, the performance is outstanding. For typical browser-based stuff and even software development, eight hours on battery is easy enough, if not more. Gaming has the usual side effects, including lower battery life and lots of heat, which is to be expected. The keyboard is adequately clicky and surprisingly stable considering it's sitting on the other screen. It's a little thicker and heavier than a similar laptop with a single screen, but not so much that it's a problem. And yes, it can even drive another external touch screen. When you peel off the keyboard and use both screens, the experience is very desktop like. If you've got a coffee table or something in front of you, you can even still use the keyboard itself on your lap, though it's not super stable that way. Using it with the screens vertical feels weird, but it's still more space than looking at a phone vertically. It's surprisingly easy to see even when outside, though at that brightness, I assume battery life takes a significant hit. The clarity and vibrancy of the OLED screens is remarkable. Overall, this design is so obvious that I don't understand how it hadn't been done before.

I have had this laptop for 5 months and I absolutely love it. I wasn't convinced at first but now I don't think I could work with out it. I need a double screen for work which meant working in my office all the time. Now I can work off my lap desk on the couch. It came in really handy when I broke my ankle and had to be on the couch elevating and icing for 8 weeks. My work didn't slow down because I had 2 screens! It is very sturdy when using the second screen, the stand is tight. It does get a lot hotter than my last asus with one screen but it is minor issue. The battery life is shorter than other laptops especially when using duel screens. It lasts about 2 hours. The Bluetooth keyboard is fantastic and lasts on batter for several hours. The sound is also good as I am on video calls much of my day and it is always crystal clear. I was hesitant with new technology but I would definitely buy this again in a heartbeat.

Upgraded from an old tablet. The dual screen appealed to me having had a dual monitor on a desktop while in school. The two screens are very nice. Managing them is easy. The weight is less than I expected from a dual screen machine. The speed of this machine is pretty disappointing, however. ...and there are idiosyncrasies that are irritating. One is that it keeps popping up notices to connect to items that are already connected. Another is the dual listing of drives/folders that require editing the register to fix. Funny that ASUS wouldn't fix this if MS wouldn't. The keyboard is slightly warped causing it to rock slightly while typing. A problem, undoubtedly, due to stresses unaccounted for in the manufacturing process. While installing Office, they offered to sell me all of the games/bloatware that would have been installed automatically in previous years. They would monetize taking a potty break if they could find a way to do it. But that is not ASUS' fault. Every computer that I've owned, including Android units, has irritations. As such, I'm keeping this unit and making the best of it. You, on the other hand, might just consider going with two separate monitors and a faster machine if that feature is what you're going for.

I purchased the laptop on May 25, 2024. It was dispatched on June 20 and delivered the following day, June 21. The box arrived intact and well-packaged inside both the Asus box and the Amazon box. The computer is heavier than I anticipated, and it consumes battery very quickly, even with just one screen active. However, I find the dual-screen concept to be awesome; I love it. When deciding between the Lenovo Yoga Book 9i and the ZenBook Duo 2024, the ZenBook seemed the logical choice due to its stronger performance, greater storage capacity, better processor, and lower price. Let's delve into the Asus ZenBook Duo 2024, a laptop that has garnered a lot of attention recently, including mine, primarily because of its dual-screen setup. One standout feature is its design. Asus has managed to keep it sleek and relatively lightweight despite incorporating two screens, thanks to advancements in power management and the use of Intel's latest 9 Ultra SoC, known for its efficiency. This is a significant improvement since dual-screen laptops in the past tended to be bulky and had short battery lives. Moving on to usability, the keyboard is quite impressive. It offers good key travel, pleasant backlighting, and a touchpad that supports gestures effectively. Asus has even addressed concerns about the keyboard's battery life when used independently from the laptop by including a USB-C charging port on the side for convenient power supply. Regarding the displays, they are sharp with both screens boasting 3K resolution and a 120 Hz refresh rate, providing crisp and smooth visuals. Performance-wise, the Intel 9 Ultra processor and 32GB of RAM ensure snappy multitasking and seamless operation of demanding applications like Adobe CC. It has significantly enhanced my productivity at work. Overall, I am thoroughly impressed with what Asus has achieved with the ZenBook Duo 2024. It's not merely a gimmick with dual screens; it genuinely enhances productivity. While the battery life could be better and the dual-screen setup may take some getting used to, for anyone needing extra screen real estate on the go, this laptop could be a game-changer. The performance has been flawless so far; there's nothing to complain about. It's one of the coolest laptops I've ever seen. You can utilize it in dual-screen mode to maximize productivity with two displays for multitasking, gaming, or even coding, which suits my needs perfectly.
