Pros
Sort
-
Setup is overwhelmingly described as quick and simple, often just plugging in one USB-C cable and extending the displays in Windows. The main exception is a defective-unit complaint that turned setup into hours of frustration.
-
Productivity is the X90E’s strongest use case. Reviewers repeatedly say the extra screens make spreadsheets, documents, coding, meetings, presentations, and travel work much easier by reducing constant window switching.
-
The single-cable USB-C setup is one of the X90E’s clearest wins. Reviewers repeatedly praise the cleaner desk, fewer adapters, and ability to run both extra screens from one connection.
-
Build quality is a major strength, with repeated praise for the metal frame, sturdy kickstand hardware, robust hinges, and a generally durable feel. Several owners describe it as solid or even tank-like.
-
Portability gets unusually split feedback. Many owners say it folds neatly, fits a laptop bag, and travels well, while experts and several customers point out the roughly 2.1–2.2 kg weight and large footprint.
-
Overall satisfaction is strongly positive, with many customers calling the X90E a game changer, a great travel tool, or an easy recommendation. The minority of negative reviews center on incompatibility, instability, dimness, or defective units.
-
Most reviewers find the screens clear, crisp, and pleasant for everyday work, with several strong customer endorsements of picture quality. Expert testing is more measured, especially for professional color work, and a small number of customers report display failures.
-
Value is widely praised, especially for getting two extra screens and a stand in one package at a comparatively modest price. A few negative experiences with brightness, stability, or outright failure make the value less convincing for those buyers.
-
The X90E generally feels more premium than its price suggests. Metal construction, a tactile frame, and the overall high-tech presentation are repeatedly praised.
-
The 1080p resolution is generally judged well matched to the 15.6-inch panels. Reviewers repeatedly describe text and images as crisp, with several saying the resolution is more than adequate for everyday work.
-
Viewing angles are consistently strong. IPS panel behavior keeps colors stable from the side, which reviewers say works well for collaboration and shared viewing.
-
The dual 15.6-inch panels are a major attraction for buyers who want more workspace. Customers especially appreciate the larger viewing area for documents and multitasking.
-
Color reproduction is generally liked, with reviewers describing rich, vibrant colors and one expert calling the included colors very accurate. That strength does not fully offset the narrower overall gamut.
-
The kickstand and screen articulation are usually praised for flexible positioning, rotation, and stable desk use. Still, several customers report fit or stability issues, including a low working height, loose-feeling support, or limited recline.
-
The design is generally well received, from the subtle gunmetal finish to the foldable, adjustable form. Reviewers tend to see it as clean and polished rather than purely utilitarian.
-
Brightness is usually considered sufficient indoors and several customers call the screens bright, but outdoor performance is less convincing. One reviewer specifically found the display too dull for daylight use.
-
Sharpness is a standout in the customer feedback that addresses it directly. Reviewers call the screens super sharp and the images super crisp.
-
Software and device compatibility is mixed. The main X90E expert reviews emphasize Windows and video-capable USB-C or Thunderbolt requirements, while some customers report seamless operation and others say the monitor would not work with their laptops.
-
Support feedback is mostly positive, with several customers praising quick, responsive, helpful service. One defective-unit buyer reports the opposite experience and criticizes the lack of live support.
-
The matte surface handles reflections well. Reviewers say it helps with bright environments and cuts distracting reflections, even though brightness itself can still be insufficient outdoors.
-
Console gaming gets one enthusiastic customer endorsement. That user reports successful PS5 use and says Call of Duty looked excellent on the screens.
-
Delivery presentation is positively described in the one direct customer report. The unit arrived in a premium-looking box and was considered very well packaged.
-
The ALT-DP USB-C connection is a strong part of the design because it can carry video to both screens through one cable. The catch is that the host device needs a compatible video-capable USB-C or Thunderbolt port.
-
Eye comfort receives limited but very positive feedback. One reviewer specifically describes the screen as easy on the eyes and clean for reading while traveling.
-
Contrast is described as decent rather than exceptional. The expert review finds it usable for the class but clearly behind higher-end OLED or MicroLED displays.
Cons
Sort
-
Power-state behavior is a serious concern in the small amount of feedback available. Two customers report unwanted shutoffs, power loss, or entry into power-saving mode during use.
-
Competitive gaming is not a strong fit. Reviewers point to the 60Hz refresh rate and explicitly frame the screens as productivity displays rather than gaming-focused panels.
-
Luminance uniformity is a weak point. The expert test found noticeably darker corners, making the backlighting less even than the rest of the picture-quality results.
-
Aspect-ratio control has one mixed customer assessment. The adjustment is said to need work, though the reviewer also says it can be worked around.
-
Port selection is restrictive. The expert review notes that the two USB-C ports are effectively split between connection and power, limiting multi-device use and leaving no HDMI input.
-
The 60Hz refresh rate is acceptable for productivity but a clear limitation for gaming. The one direct evaluation calls it a little unfortunate.
-
Speaker feedback is weak overall. One customer says the built-in audio is barely worth having, while another only notes that sound is somewhat louder than an older version.
-
Color gamut is adequate for normal office work but limited for demanding creative use. Expert testing and commentary both point to coverage that falls short of professional photo or video needs.
-
Long-term reliability is the most uneven area. Some owners expect years of use or report dependable travel performance, while others describe screens that shut off, lose power, fail to work, or arrive effectively unusable.
-
The per-screen controls are useful, but usability is mixed. One expert calls the button-driven OSD painful and dated, while a customer likes being able to adjust each screen independently.
-
The inexpensive IPS panels are considered serviceable for productivity, but they do not match OLED or MicroLED for contrast and color performance. The panel choice is practical rather than premium.
