ASUS VivoBook K571 (X571) review – something new that needs a little retouch

Let’s start by clarifying the name of this guy. In the US it is known as the VivoBook K571. However, around the world, you can find it by the X571 and N571 moniker. Yep, similarly to the Netherlands, which is known as Holland, ASUS was not very decisive, so we are going to use the VivoBook K571 from now on. Other than that, the laptop belongs to the budget gaming notebook market. What else is there? The Lenovo Ideapad L340 Gaming 15, HP Pavilion Gaming 15 (2019), Dell G3 3590 and more. Similarly to them, the VivoBook K571 features a brand new design – both inside and out.

It can be purchased with either a TN or an IPS panel with a Full HD resolution. In terms of hardware – ASUS offers the notebook with either the Core i5-9300H or the Core i7-9750H, while GPU-wise you can pick from the GeForce GTX 1050 and the GTX 1650, both equipped with 4GB of GDDR5 memory. Of course, when we talk about budget gaming machines, one should expect some setbacks. The most common of them are poor build quality, tiny battery or budget panel for the display. Nevertheless, we see this notebook as a pretty well executed and has a modern design that is well though. However, did this change when we used it for a while? Let’s see.

What’s in the box?

Inside the box, there is just the notebook, a 120W power adapter and some mandatory paperwork.


Design and construction

In terms of building materials, the VivoBook K571 features only plastic. As we mentioned, we were not expecting anything different from something at this price point. Additionally, the weight and height are not that impressive either – the laptop stands at 21.9mm and weighs 2.14 kg (4.72 lbs).

Similarly to the ZenBooks and VivoBooks, equipped with much lesser hardware, the VivoBook K571 features an ErgoLift hinge. Basically, what it does is it lifts the backside of the base so that there is more breathing space for the fans, and ultimately – a more ergonomic feel when you type. However, the case with this device is that you have to push the display almost all the way to the farthest point it can go in order for the lid to act as a lever. This means, that in most cases, it will be uncomfortable to work like that, so you may not be able to experience its perks on a daily basis.

Additionally, the lid cannot be opened with a single hand. Moreover, when you give it flex to the sides it moves quite a lot, causing the display to produce some weird bubble-like effects – similarly to when you press upon the pixels really hard. On the bright side, there is a camera, which is placed on its orthodox position above the screen.

Then, moving to the base, we see a keyboard that features the NumberPad segment. Yes, its keys are smaller than the rest of them, but it is good to see that there is any form of NumberPad, whatsoever. In addition to that, there is a backlight, and furthermore, the keyboard is fairly comfortable to use. It has a rather long keystroke and while the feedback cannot be considered as super clicky, it is not soft either. Other than that, the arrow keys are super tiny, which is not great for some gamers.

Next, there is the touchpad. Its surface feels plasticky, but the gliding and accuracy are great. Nevertheless, the palm-rest area is extremely good at catching the oils from your fingertips. Not only that but there is some noticeable bending happening when you press on the deck and around the touchpad, itself.

Lastly, let’s turn the laptop upside down and check out the massive ventilation grill. Here. you can also find the speaker cut-outs. What is interesting is the way the device exhausts its hot air. When the VivoBook K571 is in a closed position, you can see the ventilation on the back. However, in an upright pose, the hot air is blown at the display. On the bright side, there is a certain angle to the exhaust cut-outs, which guides the air upwards, rather than force it directly at the lid. Shortly, we will see how this affects the thermals around the notebook.

Ports

On the left side, you can see the charging plug, as well as an RJ-45 connector, an HDMI connector, a USB Type-A 3.1 (Gen. 1) port, a USB Type-C 3.1 (Gen. 1) port and an audio combo jack. Then, on the right, there are two USB Type-A 2.0 ports and an SD card reader.


Disassembly, upgrade options and maintenance

Should you need to remove the bottom panel of the device, you will be met with a rather interesting type of “innovation”. You are going to see only four screws, holding the entire bottom plate to the chassis. Don’t let ASUS fool you, though – there are two more hidden beneath the back feet. Cheeky job, ASUS. This totals the number of screws to six, which is still impressive, given the fact that most of the modern gaming laptops feature 10 or more.

So, the configuration of the CPU and the GPU is vertical, rather than horizontal, as seen on almost every gaming laptop out there. This results in a 90-degree bend on the heat pipes, in order to drive the heat away to the heat sinks. There are two heat pipes, which are shared between the CPU and the GPU but what is interesting is that each one of them is allocated to a separate fan. Soon, we are going to see how (or if) this affects temperatures and performance.

In terms of memory, there are 8GB soldered to the motherboard, and you are given a single RAM DIMM for upgrades. The machine supports up to 16GB of DDR4 memory. On the storage side, there is a 2.5″ SATA drive slot, and an M.2 PCIe x2 slot placed just above it.

Obviously, with a 42Wh capacity, the battery is the next cost-cutting measure, implemented by ASUS.


Display quality

ASUS VivoBook K571 comes with a Full HD IPS panel, model number LG LP156WFC-SPD1 (LGD0563). Its diagonal is 15.6″ (39.62 cm), and the resolution – 1920 х 1080p. Additionally, the screen ratio is 16:9, the pixel density – 142 ppi, their pitch – 0.18 x 0.18 mm. The screen can be considered Retina when viewed from at least 60 cm (from this distance, the average human eye can’t see the individual pixels).

Viewing angles are good. We offer images at different angles to evaluate the quality.

The maximum measured brightness is 235 nits (cd/m2) in the middle of the screen and 227 nits (cd/m2) average across the surface with a maximum deviation of 12%. The Correlated Color Temperature on a white screen and at maximum brightness is 6140K (average) – warmer than the 6500K optimum for sRGB. The average color temperature through the grey scale before profiling is 6120K.
In the illustration below you can see how the display performs from uniformity perspective. The illustration below shows how matters are for operational brightness levels (approximately 140 nits) – in this particular case at 59% Brightness (White level = 141 cd/m2, Black level = 0.12 cd/m2).
Values of dE2000 over 4.0 should not occur, and this parameter is one of the first you should check if you intend to use the laptop for color-sensitive work (a maximum tolerance of 2.0 ). The contrast ratio is excellent – 1160:1 (1090:1 after profiling).

To make sure we are on the same page, we would like to give you a little introduction to the sRGB color gamut and the Adobe RGB. To start, there’s the CIE 1976 Uniform Chromaticity Diagram that represents the visible specter of colors by the human eye, giving you a better perception of the color gamut coverage and the color accuracy.

Inside the black triangle, you will see the standard color gamut (sRGB) that is being used by millions of people in HDTV and on the web. As for the Adobe RGB, this is used in professional cameras, monitors, etc for printing. Basically, colors inside the black triangle are used by everyone and this is the essential part of the color quality and color accuracy of a mainstream notebook.

Still, we’ve included other color spaces like the famous DCI-P3 standard used by movie studios, as well as the digital UHD Rec.2020 standard. Rec.2020, however, is still a thing of the future and it’s difficult for today’s displays to cover that well. We’ve also included the so-called Michael Pointer gamut, or Pointer’s gamut, which represents the colors that naturally occur around us every day.

The yellow dotted line shows ASUS VivoBook K571’s color gamut coverage.

Its display is limited just to 53% of the sRGB/ITU-R BT.709 (web/HDTV standard) in CIE1976.

Our “Design and Gaming” profile delivers optimal color temperature (6500K) at 140 cd/m2 luminance and sRGB gamma mode.

We tested the accuracy of the display with 24 commonly used colors like light and dark human skin, blue sky, green grass, orange, etc. You can check out the results at factory condition and also, with the “Design and Gaming” profile.

Below you can compare the scores of ASUS VivoBook K571 with the default settings (left), and with the “Gaming and Web design” profile (right).

The next figure shows how well the display is able to reproduce really dark parts of an image, which is essential when watching movies or playing games in low ambient light.

The left side of the image represents the display with stock settings, while the right one is with the “Gaming and Web Design” profile activated. On the horizontal axis, you will find the grayscale and on the vertical axis – the luminance of the display. On the two graphs below you can easily check for yourself how your display handles the darkest nuances but keep in mind that this also depends on the settings of your current display, the calibration, the viewing angle, and the surrounding light conditions.

Response time (Gaming capabilities)

We test the reaction time of the pixels with the usual “black-to-white” and “white-to-black” method from 10% to 90% and vice versa.

We recorded Fall Time + Rise Time = 24 ms.


Health impact – PWM / Blue Light

PWM (Screen flickering)

Pulse-width modulation (PWM) is an easy way to control monitor brightness. When you lower the brightness, the light intensity of the backlight is not lowered, but instead turned off and on by the electronics with a frequency indistinguishable to the human eye. In these light impulses, the light/no-light time ratio varies, while brightness remains unchanged, which is harmful to your eyes. You can read more about that in our dedicated article on PWM.

ASUS VivoBook K571’s backlight is not PW-modulated at any brightness level. This ensures comfort to the eyes in this aspect.

Blue light emissions

Installing our Health-Guard profile not only eliminates PWM but also reduces the harmful Blue Light emissions while keeping the colors of the screen perceptually accurate. If you’re not familiar with the Blue light, the TL;DR version is – emissions that negatively affect your eyes, skin and your whole body. You can find more information about that in our dedicated article on Blue Light.

Conclusions

ASUS VivoBook K571 has an IPS panel with a Full HD resolution, comfortable viewing angles, good contrast ratio, and adequate default settings. Additionally, it doesn’t use PWM for brightness adjustment, while its only disadvantage is the modest color coverage.

Battery

Now, we conduct the battery tests with 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. This notebook is equipped with a 42Wh battery.

We got 5 hours and 42 minutes of Web browsing and 5 hours flat of video playback.


CPU options

In terms of processor choices, you can pick either the Core i5-9300H, which has four cores and eight threads or the Core i7-9750H – a six-core/twelve-thread CPU.


GPU options

As of the writing of this review, the ASUS X571 can be purchased with the GeForce GTX 1050 dedicated graphics card with 4GB of GDDR5 memory, or its successor – the GTX 1650 (4GB of GDDR5).

Temperatures and comfort

Max CPU load

In this test we use 100% on the CPU cores, monitoring their frequencies and chip temperature. The first column shows a computer’s reaction to a short load (2-10 seconds), the second column simulates a serious task (between 15 and 30 seconds), and the third column is a good indicator of how good the laptop is for long loads such as video rendering.

Average core frequency (base frequency + X); CPU temp.

There is something interesting here. While obviously the VivoBook K571 is oriented to being cool and relatively quiet, we needed to perform two tests, because at the first one we would get 2.00 GHz for all cores, throughout the entire time. We tried updating the BIOS – it failed. Then we tried downloading XTU in order to check for some power throttling issues. It turned out, that as soon we installed the application, the laptop managed to post the results you see up there. Without doing any changes. Then if we wanted to undervolt the processor with say – 100 milivots, we would get 400 MHz on all cores.

Real-life gaming

NVIDIA GeForce GTX 1050 GPU frequency/ Core temp (after 2 min) GPU frequency/ Core temp (after 30 min)
ASUS VivoBook K571 1491 MHz @ 69°C 1491 MHz @ 67°C
Lenovo Ideapad L340 Gaming (15″) 1691 MHz @ 74°C 1620 MHz @ 74°C
Lenovo IdeaPad 330-15ICH 1718 MHz @ 65°C 1643 MHz @ 65°C
MSI GL63 8RC (GTX 1050) 1658 MHz @ 65°C 1645 MHz @ 69°C
Dell G3 17 3779 1683 MHz @ 77°C 1670 MHz @ 88°C

Then with the graphics card, we saw rather low temps, but the frequency was some good 150 MHz off the competition, which can definitely make a difference in gaming.

Gaming comfort

While the sound coming from this machine is not very loud, the temperatures on the outside are a little high – 49C on the keyboard and over 50C on the bottom part of the lid (where the air is pushed towards).


Verdict

There you go. Another review of another budget gaming device. It was really exciting to get our hands on something that looks and feels fresh in this industry. In fact, ASUS is one of the companies that brings the most innovations on the laptop market – first, it was the ErgoLift hinge, then ScreenPad and then the ZenBook Duo, which is one of their most aggressive designs ever.

However, how was this implemented into the VivoBook K571? Well, here you can “only” see the thoughtful hinge mechanism that lifts the back of your laptop so that it breathes fresh air more easily. Well, we think that ASUS could have done a better job with this one. This is because the hinge is only effective when you push the screen as much as it cans, thus not being very comfortable if you are using the laptop on the line of your eyesight, or on a higher surface.

Then, the quality of the build is not amazing either. The lid, itself is prone to flexes, while the base bends when you press on the keyboard deck or even the palm-rest area. Speaking of the keyboard – it is one of the strong points of the device. Despite the tiny arrow keys and the sized-down NumperPad, we feel it is pretty comfortable as the keystrokes are fairly long and there is some click to them. Additionally, there is a backlight to help you with the midnight gaming.

As of the performance – it is fine. Clearly, it is not a power horse, but light to medium intensive games can be played without hesitation. Ultimately, we would recommend getting the more powerful and more efficient GeForce GTX 1650 as it will definitely make a difference.

ASUS VivoBook K571 has an IPS panel (LG LP156WFC-SPD1 (LGD0563)) with a Full HD resolution, comfortable viewing angles, good contrast ratio, and adequate default settings. Additionally, it doesn’t use PWM for brightness adjustment, while its only disadvantage is the modest color coverage.

Then, in terms of upgradability, you have a decent package – you can install M.2 drives with speeds of up to PCIe x2, and there is a 2.5″ SATA drive slot. Memory-wise the picture is not that colorful, as there are 8GB soldered to the motherboard and only one RAM DIMM. Moreover, it can total at 16GB, compared to 32GB in some of the competition. Additionally, the I/O is impressive by having an Ethernet port, USB Type-C, and an SD card reader, on top of the other stuff. However, we were not very pleased by the 5Gbps limit on the Type-C and the duo of super slow USB Type-A 2.0 ports.

Lastly, there is the battery life, which as expected from a 42Wh unit is mediocre – 5 hours and 40 minutes of Web browsing and 5 hours flat during video playback.

So, all in all – the machine is easy and fast to use. However, some issues like the power management with the current BIOS version, battery life, and some other little annoyances may lead you towards the HP Pavilion Gaming 15 or the Acer Aspire 7 (A715-74G) for example.

Pros

  • ErgoLift hinge and subjectively cool exterior
  • Backlit keyboard
  • Features an SD card
  • Adequate price
  • Lacks PWM for brightness adjustment (LG LP156WFC-SPD1 (LGD0563))


Cons

  • Budget build quality
  • Weird power management with BIOS version 302
  • Covers only 53% of sRGB (LG LP156WFC-SPD1 (LGD0563))
  • Only one RAM DIMM and maximum support of 16GB of memory
  • Most of the USB ports are 2.0
  • Gets a little warm on the outside

I’ve seen many comments that say the same. It is not meant for lasting long because it made the laptop cheaper. Did you charge the laptop 3 hours before using it? I am receiving mine next week.
