Acer Extensa 15 (EX215-55) review – Affordable and Upgradable, But the Screen Needs Attention
The Acer Extensa 15 (EX215-55) has some advantages over the Extensa 15 (EX215-33) that we have already tested in depth. The EX215-55 model has a pair of DDR4 SODIMMs, an additional M.2 slot, and even a SATA slot for normal SSDs or 2.5″ SSDs. It’s also powered by more punchy Alder Lake CPUs with P cores. Still, it lacks Type-C connectors, while the EX215-33 at least has one. Overall, these are the most notable differences between the two siblings.
Unfortunately, we didn’t find a laptop with the top-end 1080p IPS screen so we settled for a TN unit with the same resolution. The only pro of the latter is the lower end price. Aside from that, the viewing angles, the sRGB coverage, and the contrast ratio are just bad. Acer even sells this Extensa 15 with a low-res 768p display. This model should be avoided at all costs.
The keyboard has a NumPad which may be useful for some users but the lack of a backlight could be a no-go for the night owls.

What’s in the box?
We found a bit of paperwork and a 45W barrel plug adapter.
Design and construction
If we don’t count the slightly different port placement on the left, the Extensa 15 (EX215-55) looks the same as the EX215-33 version. It’s also slightly heavier and thicker than the latter. That’s perhaps due to the added RAM and SSD slots. The machine stops the scales at 1.78 kilos and the profile is 19.9 mm.
The chassis is made of plastic. Curiously, you can open the lid with one hand. Before reaching the 90-degree mark, the front of the base jumps up but if you push back the lid a bit harder it’ll open even wider. Nice, we didn’t expect that! The rigidity of the build is still average at best but that’s kind of expected in the ultra-budget class.
The TN screen of our machine is surrounded by thick bezels, straight out of 2015. The 720p Web camera on top lacks a privacy shutter but it sports Temporal Noise Reduction tech.
When you open the lid past 90 degrees, its bottom feet lift the back of the laptop up. Cool idea, except the screen’s viewing angles are so bad, you can’t see a thing when the lid is tilted like this.
We will remind you once again that the keyboard doesn’t have a backlight. Aside from that, the unit ain’t bad for normal usage. The key travel is relatively moderate and the feedback is okay-ish.
Strangely, the touchpad here feels different than the one of the EX215-33 model. It ain’t that smooth and tracking is a bit off.
You can have a sneak peek at the cooling through the sizable ventilation grill on the bottom plate. There, you can also spot four rubber feet and cutouts for the speakers. The hot air is directed via a small vent on the rear. The CPU doesn’t dissipate too much heat but since the back exhaust points at the lower screen bezel, a bit of heat makes its way to the display during full system loads.
Ports
On the left, you get a power connector, LAN, an HDM 2.1, and two 5 Gbps USB Type-A 3.2 (Gen. 1) ports. The right side houses a Lock slot, another 5 Gbps USB Type-A 3.2 (Gen. 1) port, and an Audio combo jack.

Viewing Angles
Viewing angles are good. We take photos from different angles to evaluate the quality.
Also, a video with locked focus and exposure.
Color Coverage
The whole “sail-shaped” map below (Fig. 1) consists of all the colors we can see, while the black crooked line shows all the colors from real-world scenes and nature around us.
Then, we’ve drawn some of the most important and interesting color spaces, compared to the colors the panel of Acer Extensa 15 (EX215-55) can show:
Standard/For Web: sRGB – widely used color space for most consumer devices, ideal for Web design and development
For Print: AdobeRGB – used in professional photo editing, graphic design, and print
For Photographers/Video Editors: DCI-P3 – used in high-end film production, post-production, and digital cinema
Premium HDR: Rec.2020 – the widest consumer ITU color standard, covering a massive 75.8% of the visible spectrum, a benchmark for premium HDR content
Acer Extensa 15 (EX215-55): the yellow dashed triangle (– – – – – –) represents the range of colors this monitor can display.
In our tests, we calculated the total color coverage of the monitor at 50% of the sRGB color gamut and 39% of the DCI-P3 color gamut.
(Fig.1) Acer Extensa 15 (EX215-55) covers 50% of the sRGB gamut
Brightness and Contrast
The maximum brightness in SDR mode is 236 cd/m² in the center of the screen and 222 cd/m² averaged across the surface with a maximum deviation of 11%.
The Correlated Color Temperature (CCT) on a white screen at maximum brightness is 6570K.
The contrast ratio is 370:1.
Uniformity: Luminance, Contrast, and Color Deviation
The figure below shows the results from our uniformity test across different sections of the screen. It’s measured at 179 nits (Windows slider = 72%) — a brightness level we consider typical for standard working conditions.
DeltaE values below 4.0 are acceptable for regular users. For those working with colors, screens with DeltaE values no higher than 2.0 are recommended.
Color Accuracy
Let’s check the difference between real colors and those you’ll see on the Acer Extensa 15 (EX215-55). We measure that distance in DeltaE – the higher the number, the more different they look.
Values below 4.0 are acceptable for regular users, while values below 2.0 are suitable for color-sensitive work. A value below 1.0 means the difference is indistinguishable to the naked eye.
For the next graph, we’ve selected 24 common colors, including dark/light skin, blue sky, green grass, etc.
Before our calibration of the Acer Extensa 15 (EX215-55), the Average color accuracy was 9.3 dE (Fig. 2), and with our Design and Office profile, it lowered to 3.6 dE (Fig. 3).

Visibility in dark scenes
Have you ever watched a movie with dark scenes where you could barely see anything? This often happens because many display panels struggle to differentiate the darkest nuances, making them appear the same.
The next figure illustrates how well the display reproduces these dark nuances. The left side of the image shows the display with stock settings, and the right side shows it with our Gaming and movies profile activated.
On the horizontal axis are the grayscale levels, and on the vertical axis – the corresponding display brightness.
You can also check how your display handles the darkest nuances but keep in mind that this also depends on the settings of your current display 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 = 9.6 ms. Short pixel response time is a prerequisite for a smooth picture in dynamic scenes.
Health Impact: PWM (Screen flickering)
Some use PWM to regulate their brightness, which means that instead of reducing the light intensity, they pulse or flicker. Our brain merges the image, so it appears darker, but this strains both it and our vision, especially when the frequency of the pulses is low. You can read more about that in our dedicated article on PWM.
In the graph below, you see the intensity of light at different brightness levels—on the vertical axis is the brightness of the emitted light, and on the horizontal axis—time.
The light from the backlight of the Acer Extensa 15 (EX215-55) display is not pulse-width modulated, providing visual comfort in the discussed aspect.
Health Impact: Blue light emissions
Installing our Health-Guard profile not only eliminates harmful PWM when the laptop uses it to control brightness but also reduces 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.
Health Impact: Screen Reflectance
Glossy-coated displays can cause eye fatigue in high ambient light conditions due to reflections. We measure the level of screen reflection with the display turned off, at a 60° angle.
The reflectance of the Acer Extensa 15’s screen is 49.3 GU.
High Gloss: >70 GU
Medium Gloss: 30 – 70 GU
Low Gloss: <30 GU

The Extensa 15 (EX215-55) and its simple-looking cooling system are doing a good job even when the Core i3-1215U is pounded with heavy loads for a long time where its P and E cores boost to 3.12 GHz / 2.38 GHz.
Gaming comfort
The single fan isn’t exactly quiet in “Best performance” mode when the processor is stressed at max, but the noise isn’t too high either. The keyboard feels just slightly warm on the left.
Battery
Now, we conduct the battery tests with the Windows Best Power Efficiency setting turned on, screen brightness adjusted to 180 nits and all other programs turned off except for the one we are testing the notebook with. This laptop’s 55Wh battery lasts for around 7 hours of video playback. Оur test was conducted with the “Battery Saver” preset activated in the Windows “Power & Battery” menu.

Disassembly, Upgrade options, and Maintenance
To remove the bottom plate, undo the ten Philips-head screws that hold it in place. Pop the areas behind the hinges and the top edges with a thin plastic tool. Then, fully pry the back and work your way around the sides and the front.
Keep in mind that the front clips are very stiff, and with zero gaps between the plate and chassis, prying this side requires care and patience.
Here’s how the bottom panel looks on the inside.
The device in front of us has the optional 55Wh battery. The default version is a 40Wh variant. To take it out, detach the connector from the motherboard by pulling it towards the battery and undo the two Philips-head screws that keep the unit in place. The capacity is enough for around 7 hours of video playback.
According to Acer, the two SODIMMs fit up to 32GB of DDR4-3200MHz memory in dual-channel mode. However, since the CPU can support up to 64GB, this laptop likely wouldn’t have issues running a larger amount of memory than the official manufacturer’s specified limit. For storage, there is a pair of two M.2 slots – one for Gen 4 and one for Gen 3 SSDs.
The two standoffs below the storage drives prevent possible SSD bends which is a nice touch. The SATA slot for regular HDDs or SSDs is on the left of the cooling.
The upgradable Wi-Fi 5 card is positioned below the fan.
The thermal system comprises one fan, a heat pipe, one heat sink, and a heat spreader.
Verdict
The Extensa 15 (EX215-55) could be a good daily driver for budget-conscious users. Even the Core i3-1215U is just okay for work if it’s accompanied by at least 16GB of RAM in dual-channel mode and a decent SSD. Just be careful not to pick a machine with a TN screen.
The 1080p TN display (B156HTN06.1 (AUO61ED)) disappoints. Its viewing angles are super narrow, the color coverage is low, the contact ratio is just 370:1, and the out-of-the-box color accuracy is absurd (average dE 9.3). At least you can fix the accuracy with the aid of our “Design and Office” profile.
The EX215-33 iteration of Acer Extensa 15 may tempt value-seeking users with a pleasant price, high CPU clocks during long stress, good upgradability, and decent port selection.
You can check the prices and configurations in our Specs System: https://laptopmedia.com/series/acer-extensa-15-ex215-55/
