LG Gram 17 17Z90N Review: A light and mobile 17-inch laptop with a 16:10 display

Lightweight. With the Gram 17 17Z90N, LG delivers a feather-light 17-inch laptop that offers a display in the 16:10 format. The rest of the equipment is also fitting: Ice Lake processor, NVMe SSD, 16 GB of working memory (dual-channel mode), and Thunderbolt 3. All this is accompanied by outstanding battery life.
Sascha Mölck, 👁 Sebastian Jentsch, Andrea Grüblinger (translated by Mark Riege),

Despite its 17-inch format, the LG Gram 17 belongs to the group of slim and mobile office laptops. Its weight of about 1,350 grams (~2.98 lb) remains below that of most 14- and 15.6-inch laptops. You won't find a lighter 17-inch laptop. In addition to the low weight, the 16:10 display represents another selling point of the laptop.

There are no direct competitors in our database. All the 17-inch laptops turn out more bulky, are at least 1 kg (~2.2 lb) heavier, and offer 16:9 displays. While there are some models with 16:10 displays in our database, they are several years old. We are therefore using current 17.3-inch office laptops such as the HP 470 G7, the Asus VivoBook 17 M712DA, and the Medion Akoya P17605 for our comparison.

Case - The Gram has a magnesium case

When you first touch the very elegant and slim case, you might think that it is made of plastic. But this is not the case. Instead, it uses a magnesium alloy that only brings little weight to the scale. LG provides the silver-gray case ("Dark Silver") with smooth and matte surfaces that are proven to be hardly or not at all susceptible to fingerprints. Despite its very simple design, the case looks very sleek and would look good on any desk. The battery is built in, and there is no maintenance flap.

The device deserves some praise for its excellent workmanship. There are no gaps and no noticeable sharp edges. However, the light build and the magnesium case also require some compromises. The base unit, and even more so the lid, can be warped. While the back of the lid wobbles significantly when applying pressure, there are no changes in the image resulting from the pressure. The hinges hold the display tightly in position but wobble slightly. The maximum opening angle is about 140°, and you can open the display using one hand. 

The Gram brings a weight of about 1,350 grams (~2.98 lb) to the scale, which is the same as its predecessor. The case of the new model turns out minimally more compact than the case of the LG Gram 17Z990.

Equipment - Thunderbolt 3 on board

Despite its compact size, LG has equipped the Gram with a solid selection of connections. There are three USB Type-A ports (USB 3.2 Gen 1), which are accompanied by one Thunderbolt-3 port that allows connecting a docking solution or an external GPU. Power delivery and DisplayPort are supported via USB-C, so together with the HDMI port, the notebook offers two video ports. The ports are placed in the back area on the left and right sides, so the areas next to the palm rests will remain free of cables.

SD Card Reader

The LG laptop does not offer a full-size storage card reader, but uses a microSD model instead. With maximum transfer rates of 80.5 MB/s (transfer of 250 jpg image files of about 5 MB each) and 88.9 MB/s (copying large data blocks), it belongs to the faster representatives of its kind. We test the card readers using a reference storage card (Toshiba Exceria Pro M501 microSDXC 64 GB).

Communication

The Intel WLAN chip (Wi-Fi 6 AX201) supports the 802.11a/b/g/n/ac/ax WLAN standards and in addition also offers Bluetooth 5 functionality. The transfer speeds we measure under optimal conditions (no other WLAN devices close by, close distance between laptop and server PC) turn out excellent. In order to support wired network connections, LG also includes a USB-Type-C-to-Ethernet adapter.

Webcam

The 0.9 MP webcam produces images with a maximum resolution of 1280x720 pixels. The results turn out slightly washed-out. In addition color accuracy is also lacking, and with a color deviation of about 18, the target (DeltaE < 3) is clearly missed.

Accessories

In addition to the usual paperwork (warranty information, quick-start instructions), the box also includes a USB-Type-C-to-Ethernet adapter and a transparent rubber mat to protect the keyboard.

Maintenance

The Gram did not turn out particularly maintenance friendly. In order to access the hardware, the bottom of the case has to be removed. Some of the screws are covered by little plastic plates that can be removed using a very small screwdriver or similar tool. The five rubber feet hide more screws. We were able to loosen the glued-in rubber feet with a small plastic spatula.  

After all the screws were removed, you have to take off the bottom of the case. You need to be very careful, since the fragile case bottom bends easily. The left and right sides, as well as the front can be unclipped using a spatula or similar prying tool. The back is secured with additional clips that can be loosened by some careful wiggling.

Warranty

LG offers a two-year warranty for the 17-inch laptop. Extending the warranty to five years will cost 120 Euros (~$142).

Input Devices - Gram 17 with keyboard illumination

Keyboard

LG's 17-inch laptop uses an illuminated chiclet keyboard, with keys that offer a short stroke and clear pressure point. The key resistance is basically okay, but could have been a tad crisper for our tastes. All the keys present a smooth surface and that of the main keys is also concave. The keyboard bounces slightly while typing, but this does not turn out to be annoying. The keyboard illumination (two steps of brightness) is controlled via a function key. Overall, LG delivers a keyboard suitable for daily typing tasks here. 

Touchpad

The multi-touch capable ClickPad has a footprint of about 12 x 7.8 cm (~4.7 x 3.1 in), offering a lot of space for using gesture controls. The smooth pad surface makes sliding your fingers over it easy, and the pad also responds to input in the corners. It offers a short stroke and a clear pressure point.

Display - 16:10 format with a WQXGA resolution

The LG laptop brings a reflective 17-inch display in the 16:10 format, offering a native resolution of 2560x1600 pixels. The contrast of 1077:1 and brightness of 354 cd/m² are attractive. While the maximum brightness drops slightly in battery operation, it is still more than 300 cd/m². Another positive point is that the display does not produce any PWM flickering at any time.

* ... smaller is better

The display offers a decent color reproduction already in the state of delivery. However, with a Delta-E 2000 color deviation of almost 5, it misses the target (DeltaE < 3). The display does not suffer from a blue tint. You can achieve further improvement via calibration. The color deviation then drops to 1.22 and the Grayscale reproduction is more balanced. The AdobeRGB (59%) and sRGB (93%) color spaces are not completely covered.

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
25 ms ... rise ↗ and fall ↘ combined↗ 14 ms rise
↘ 11 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 43 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (24.4 ms).
       Response Time 50% Grey to 80% Grey
43 ms ... rise ↗ and fall ↘ combined↗ 20 ms rise
↘ 23 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 60 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (38.8 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17714 (minimum: 5 - maximum: 2500000) Hz was measured.

LG has equipped the Gram with an IPS panel with stable viewing angles, allowing you to read the display from any position. While the brightness and contrast would allow reading the display outdoors, the reflective display surface usually makes this very difficult.

Performance - Sufficient for office and Internet

With the Gram 17, LG offers a mobile 17-inch laptop that is targeted toward private and professional users. The laptop offers more than sufficient computing power for office and Internet applications. Our test unit is available for about 1,700 Euros (~$2,010). Other equipment configurations are also available with prices starting at about 1,280 Euros (~$1,513; about $1,400 in the US).

Processor

LG uses a Core i7-1065G7 quad-core processor (Ice Lake) from Intel. This ULV model has a basic clock speed of 1.3 GHz, which can be increased via Turbo up to 3.4 GHz (four cores) or 3.9 GHz (single core). Hyper-Threading (two threads running per core) is supported.

The multithread tests of the Cinebench benchmarks run at 2.7 to 2.9 GHz for a short time period in the beginning, before the clock speed drops to 1.9 - 2.1 GHz. The single-thread tests run at 3.4 - 3.9 GHz, and in battery operation, the clock speeds are between 1.5 and 3.4 GHz (single and multithread).

Single-thread (plugged in)

We evaluate whether the CPU Turbo is also used constantly in mains operation by running the multithread test of the Cinebench R15 benchmarks for at least 30 minutes in a constant loop. From the first to the second run, the results drop sharply, and the Turbo is used at a very low level.

The Core i7 clearly remains behind the Core i7-8565U processor used in the predecessor. The Ice Lake processor only maintains a computing performance at the same level for very brief performance peaks. The 1065G7 is also unable to move ahead of the Core i5-1035G7 processor of the LG Gram 15. The results of the remaining benchmarks are also relatively close together, showing that the Core i7 does not bring any advantage. Most users will be better served with the more affordable Core-i5 model of the Gram 17.

The LG Control Center offers the option to activate a silent mode, where the CPU runs at speeds that are reduced even more and the fan remains quiet most of the time. The multithread performance then drops even sharper than the single-thread performance. However, the latter is significantly more important in everyday operation, so the laptop can still be used without any problems.

Graphics Card

Intel's Iris Plus Graphics G7 graphics core is responsible for the graphics output. The GPU supports DirectX 12 and reaches operating speeds of up to 1100 MHz. The results in the 3DMark benchmarks turn out to be decent but remain behind the capabilities of the GPU.

Note that the 3DMark results of the Gram 17 and the Gram 15 show significant differences despite having the same GPU, since the working memory of the Gram 15 runs in single-channel mode.

Gaming Performance

The Gram is not a gaming laptop. Regardless of this, the built-in hardware is able to bring quite a few games to the screen smoothly. This includes games that don't pose particularly high demands. Usually playable frame rates can be achieved at low resolutions and low to medium quality settings. In some cases, things turn out even better. However, since the CPU and GPU remain behind their full capabilities, overall the frame rates turn out lower than with other Core i7-1065G7 laptops.

Emissions - The LG computer runs quietly or remains silent

Noise Emissions

Over the whole load spectrum, the Gram hardly produces any noise, so it is also suited as a device for working in quiet surroundings. During idle operation, the fan often remains turned off and the laptop operates in complete silence. Under load, the fan hardly revs up. We measure a maximum noise level of 32.7 dB(A) during the stress test.

The operation can become even quieter by activating the Silent Mode in the LG Control Center. However, this will limit the computing performance.

Temperature

The Gram during the stress test.
The Gram during the stress test.

Our stress test (with Prime95 and FurMark running for at least one hour) represents an extreme scenario that does not occur in everyday operation. Using this test, we evaluate whether the system also remains stable under full load. Already after a short time, the CPU and GPU speeds are throttled down to 700-800 MHz and 300-500 MHz, respectively, and then remain at that level - in both mains and battery operation.

The laptop never becomes particularly hot at any time. During the stress test, we measure temperatures in the lower 40 °C range (104 °F) in two measurement spots. In everyday operation, the temperatures remain within the green range.

Speakers

The stereo speakers are positioned at the bottom of the case. While they produce a decent sound, it lacks bass. For better sound enjoyment you have to use headphones or external speakers.
