ASUS brought to Brazil in April of this year the new Asus ZenBook 14 UX434 review with few visual changes compared to its predecessor, but with ScreenPad 2.0 as the main highlight of this generation, to provide more productivity to those who will use it for work.


 What can the company’s ultra-thin notebook over-deliver to the user?  

 Visual and construction:

 It is not for nothing that the ZenBook 14 falls into the category of ultrathin.  He manages to deliver a 13-inch laptop body to a 14-inch machine.  Altogether, the use of the display is 92%, which leaves the product with very thin edges – where the webcam and 3D infrared camera are, for facial recognition.


 The design is similar to A4 size paper.  The dimensions when closed are 319 x 199 mm.  In addition, it has a weight of 1.26 kg.  The notebook is constructed of metal and has MIL-STD 810G resistance military certification.  It is possible to perceive its durability and rigidity when running your hand over the material.


 ASUS maintained the ErgoLift feature in it.  As we explained in the review of the VivoBook 15 X512JP, this design feat allows the bottom portion of the screen to become one of the bases of the notebook, to generate a three-degree tilt in the keyboard area.

 In practice, the functionality can keep the cooling system running efficiently – even when this notebook heats up, it can quickly reduce the heat – and improves typing.


 In order to keep a box proportionally compact in relation to the product it brings, ASUS did not overdo the accessories contained in the packaging.  The buyer will have, in addition to the notebook itself, the power cable – divided into two parts – and a USB adapter for RJ-45 network cable.


 Screen and multimedia:

 For the ZenBook 14 UX434, ASUS decided to insert a 14-inch IPS LCD panel, with Full HD resolution (1920 x 1080 pixels) and 300 nits of lighting.  And he got the decision right.

 Although a little reflective depending on the level of brightness you use – nothing that will bother you – the machine’s screen can deliver a good field of view from all angles.  This way, you will not experience distortion depending on the position of the laptop.

 On the other hand, the brightness suits those who like a very strong light.  But for those who prefer something darker, a finer adjustment of this attribute is missing.  Failing that, it may often be necessary to have to change manually throughout the day.

 In sound, with Harman Kardon quality, the quality is very satisfactory, especially in the bass.  But ZenBook 14 sinks – just like VivoBook 15 – in volume.  To compensate for this by giving up a bit of quality for a louder sound, it is the same process: Control Panel> Sound> Speakers (right click)> Properties> Advanced> uncheck “Enable audio enhancements”  .

 Keyboard and connections:

 The keyboard does not have a dedicated numeric section, which would increase the dimensions of the chassis if any.  However, the user need not worry about this point.  The keys are very spacious and firm to type, without making a noise.

 The signaling of the buttons follows in gray, as well as the one seen – and criticized by this site – on VivoBook 15. But there is an important difference here: the keyboard of the ZenBook 14 is backlit.  So, no matter how much light is on the body, the keys will always be highlighted.

 In terms of connectivity, the laptop has the advantage of already having support for Wi-Fi 6, a standard that allows up to three times more speed than its predecessor.  In addition, Bluetooth here is version 5.0 and offers precision and stability in connections, even with more than one device at the same time.

 This model also delivers a USB 3.1 Gen 2 port, a USB-C 3.1 Gen 2, a USB 2.0, an HDMI, Audio Jack and microSD card reader.

 ScreenPad 2.0:

 We come to the highlight of the ZenBook 14 UX434: the ScreenPad 2.0.  It consists of a second screen – touch sensitive – in place of the conventional touchpad, with a focus on giving more productivity and improving the machine’s multitasking capacity.


 The size also increased: it was 5.5 inches (1920 x 1080 pixels) to 5.65 inches (2160 x 1080 pixels).  Despite the resolution, there is the possibility to change it to 1000 x 500 pixels – which improves the display in browsers, for example.  The brightness, the theme (light or dark) and the background are also adjustable.

 ASUS changed the display with an independent interface from the previous generation to a fully integrated Windows this time.  The result is greater integration with the main screen.  The ScreenPad turns out to be an extension of the primary panel, similar to what is observed when connecting a second independent monitor.

 If the person does not want the ScreenPad on, you can use the F6 key to switch to a common touchpad or even turn off the component.

 Main functions:

 The manufacturer has deployed a number of features dedicated to ScreenPad 2.0.  Among them, there is a numeric touch keyboard – as we said earlier, there is not that section between the physical keys -, a handwriting application, a tool – Quick Key – with shortcuts to commands and programs that allow you to optimize the use of the three  main software of the Office package: Slide Xpert – for PowerPoint -, Doc Xpert – for Word – and Sheet Xpert – for Excel.

 The ZenBook 14 UX434 owner can still open browsers or even the file explorer on the second screen.  But, in these cases, the ideal is to use the lower resolution, so that the content appears in a larger size and more visible to the user.

 One of the ScreenPad’s most attractive possibilities is multi-screen.  For those who like to watch TV channels via streaming or some video platform while working or performing another activity on the main monitor, the secondary display allows you to insert a video in full screen.


 In the main technical specifications, the ZenBook 14 UX434 comes equipped with an Intel Core i7-10510U processor (10th generation), 8 GB of RAM and 256 GB of SSD PCIe M.2 storage.  According to ASUS, there is an extra M.2 slot to upgrade internally, but there is no cover to facilitate this process.

 There is no dedicated video card here.  This generates a loss of range of possibilities, but it is not the proposal of this machine to serve an audience that needs this component.

 Anyway, it shouldn’t be a problem for you to carry out simpler edits in Adobe package programs, such as Photoshop and Premiere Pro. Recording in 4K or Full HD with multiple layers can cause difficulties.


 In the benchmarks, due to the laptop category that the ZenBook 14 fits into, we can compare it to Dell’s XPS 13 9300 – which has also been reviewed by us.  In GeekBench 5.2, the single-core was above the competitor, while with multiple cores it remained a little below.

 In PCMark 10, which focuses on productivity and CPU, ZenBook registered 3,601 points, more than 500 more than Dell’s rival.  In 3DMark, it was about 50% below – this shows that the Intel HD Graphics 620 is well behind the also integrated and latest Intel Iris Plus.


 Before detailing how each game yielded, it is important to note that the purpose of this notebook is not to play.  Therefore, the yield is not expected to be satisfactory.  Even so,  tested three low and intermediate demanding titles in 1080p resolution: Fall Guys, Street Fighter V and NBA 2K20.

 The first was the one that performed best, keeping between 20 and 30 fps.  The last two are below 15 fps most of the time, as you can see in the screenshots below:


 On battery, ASUS promises an autonomy of up to 10 hours away from the outlet, with the second display on.  In the test, we experiment in three different situations: two for work and one for personal use.

 In professional situations, it was possible to obtain 5 hours and 40 minutes of continuous use with an hour and a half of videoconference and the rest in Word and browsers;  and 6 hours and 5 minutes when using essentially programs like Word, Photoshop and web browsing.

 For personal use, when alternating periods of video streaming, music streaming, YouTube, social networks and web browsing, the duration was 6 hours and 49 minutes away from the outlet.

 All scenarios used native brightness and performance settings, with ScreenPad 2.0 on – the machine’s default option.  The trend is that, without the second screen, it is possible to obtain more usage time.


 ASUS has technology that allows a service life up to 2.5 times longer.  One of the points noted for this is to decrease the recharge time from a certain percentage.

 In the test, it was possible to fully charge the battery of the ZenBook 14 UX434 in 2 hours and 52 minutes.  After 50 minutes, 55% charge is possible.  See the screenshots below:

 Final considerations:

 The great highlight of this machine is the ScreenPad 2.0.  The second screen pleases and gives practical results to those who need productivity in their professional lives.  With it, the user can bring some information or documents to the smaller display, which would avoid having to switch between windows.

 This is also the ideal notebook for those who like to consume multimedia while performing another task, or as multi-screens for streaming TV channels, for example.

 The portability feature of the ZenBook 14 UX434 allows you to easily transport it to another place, without weighing too much in your backpack or purse.  And military resistance certification, another of its differentials, guarantees durability for these changes in the environment and displacements.

 It is important to note that this is not a machine for graphic performance.  If your goal is to buy a notebook that offers good performance in games or heavier editions, along with portability, this is not the case here.  The absence of a dedicated GPU makes the difference in these types of uses.


  •  IPScreen.

  • ScreenPad 2.0.

  • Compact and lightweight body.

  • Military certification.

  • SSD storage.

  • Wi-Fi 6.


  •  Lack of dedicated GPU

  • Sound with low maximum volume

  • Autonomy below suggested


 The ZenBook 14 UX434 is a notebook intended for professional use.  And as usually happens with ultrafines in this category, there are always some “luxuries” that set them apart from the others.  In this case, it is ScreenPad 2.0 to increase users’ productivity, which actually happens in practice.

 It would be equated with a Dell XPS 13 or an Apple MacBook Air, but ASUS manages to keep the price lower than its direct competitors, which can be attractive to interested parties.

 However, having the lowest price does not mean being cheap.  The laptop arrived in the country for  $ 450, but can already be found in the ASUS official store for  $ 480 (or  $ 430, in cash).  In online retailers, the consumer can still find cheaper, even in the range of  $ 3,60 – for this last value, it already becomes an interesting option, for the current value standards in the country.
