ASUS ZenBook 14 Flip OLED (UP5401) – Top 5 Pros and Cons
ZenBooks have been ASUS’s halo devices, striving to be as innovative as ever, being the first to implement new technologies and hardware. Today’s laptop is a smaller one, coming with a portable and high-end design, along with a smaller 14-inch display, Tiger Lake processors, and integrated graphics.
Obviously, performance won’t be on par with bigger and better laptops, but we are talking about a very portable device that you can take anywhere with you and not be a hassle.
Today we are presenting you with LaptopMedia’s top 5 picks about the ASUS ZenBook 14 Flip OLED (UP5401).
4 reasons to BUY the ASUS ZenBook 14 Flip OLED (UP5401)
1. Design and build quality
The laptop comes with an exceptionally sturdy aluminum body. The lid is incredibly durable, thanks to both the aluminum construction and the glass display cover. On the back, we find the ZenBook’s calling card, the circular brushed finish, with a glossy ASUS logo that is off-centered, and the whole design revolves around it. The hinges are very well balanced, allowing the lid to open with one hand. In terms of dimensions, the laptop stops the scales at 1.40 kg and has a profile of 15.9 mm.
Despite its small stature, the laptop packs two Thunderbolt 4 ports, a single USB Type-A 3.2 (Gen. 2) port, an HDMI 2.0 port, a 3.5 mm audio jack, and a MicroSD card reader.
3. Display quality
The 2.8K OLED panel that we have here is great, but not perfect. It struggles with some problems, but first, let’s spew out what it gets right. The viewing angles are fantastic, and the peak brightness is very high, measuring at 361 nits (cd/m2) in the middle of the screen and 362 nits (cd/m2) as an average, with a maximum deviation of only 1%, leading to some of the best brightness uniformity that we have seen. This means that the brightness is even across the entire display area, leading to even color representation. Due to the nature of OLED panels, the contrast ratio is infinite. The color coverage is very good as well, as the panel covers the sRGB and DCI-P3 gamuts fully.
Something which we dislike is the PWM usage, as the notebook uses it at all times. Up to 80 nits, the pulsations are low-frequency, leading to high eye strain. After 80 nits, there are small pulsations, which are relatively safe. Still, our Health-Guard profile eliminates the PWM completely.
We tested the accuracy with both stock settings and with our Design and Gaming profile, in both the sRGB gamut and in the DCI-P3 gamut using a D65 white point, which is how we got our best result, reaching a dE value of 2.3, which is still higher than the desired <2 but we’ll take what we can get. Here are the results in factory condition (left) and with our profile applied (right).
Buy our profiles

In addition to receiving efficient and health-friendly profiles, by buying LaptopMedia's products you also support the development of our labs, where we test devices in order to produce the most objective reviews possible.
Office Work should be used mostly by users who spend most of the time looking at pieces of text, tables or just surfing. This profile aims to deliver better distinctness and clarity by keeping a flat gamma curve (2.20), native color temperature and perceptually accurate colors.
Design and Gaming
This profile is aimed at designers who work with colors professionally, and for games and movies as well. Design and Gaming takes display panels to their limits, making them as accurate as possible in the sRGB IEC61966-2-1 standard for Web and HDTV, at white point D65.
Health-Guard eliminates the harmful Pulse-Width Modulation (PWM) and reduces the negative Blue Light which affects our eyes and body. Since it’s custom tailored for every panel, it manages to keep the colors perceptually accurate. Health-Guard simulates paper so the pressure on the eyes is greatly reduced.

4. Battery life
Now, we conduct the battery tests with the Windows Better performance setting turned on, screen brightness adjusted to 120 nits, and all other programs turned off except for the one we are testing the notebook with. The 63Wh battery pack does pairs decently well with the Tiger Lake U-series chips, delivering up to 10 hours and 53 minutes of Web browsing, or 8 hours and 44 minutes of video playback.
1 reason NOT to buy the ASUS ZenBook 14 Flip OLED (UP5401)
While it didn’t compromise the I/O, the portable dimensions of the device definitely interfered with the upgradeability, leaving it with soldered RAM, of which you can pick either 8GB or 16GB of LPDDR4x memory. Storage-wise, there is a single M.2 PCIe x4 slot for storage expansion.
