AI Verdict
This is a 27-inch 1080p VA panel with a 144Hz refresh rate and tilt-only stand, best for casual gaming and basic office tasks on a tight budget.
This monitor is a situational fit for its price band, offering a 27-inch 1080p VA panel with 144Hz refresh rate. It delivers a large screen and smoother motion than 60Hz, but the low pixel density and VA panel ghosting mean it's not for everyone. The tilt-only stand and limited ports are compromises for the budget.
If 1080p on 27 inches isn't sharp enough, look for a 27-inch 1440p monitor for a significant pixel density upgrade.

Pros
- The 27-inch VA panel offers a 4000:1 contrast ratio, delivering deeper blacks than IPS panels.
- It provides a 144Hz refresh rate via HDMI, making gameplay smoother than 60Hz monitors.

- Features like Flicker-free technology and a Blue light filter, along with TÜV Rheinland certification, aim to reduce eye strain.
- Its three-sided slim bezels and ultrathin frameless design maximize screen space.
- Includes VESA 100x100mm mounting support for alternative stand options.
Cons
- The 1080p resolution on a 27-inch screen results in a lower pixel density, which can make text and images appear less sharp.
- Users report noticeable ghosting and smearing, especially in fast-paced games, which is common for VA panels.
- The stand only allows for tilt adjustment (-5° to +15°), lacking height, swivel, or pivot adjustments.

- HDR10 support is present, but user feedback indicates it's not as impactful as on higher-end monitors.
Dimension Scores
The VA panel offers a 4000:1 contrast ratio and 99% sRGB coverage, but 1080p on 27 inches results in low pixel density and some users report saturated colors.
It offers a 144Hz refresh rate and FreeSync, but significant user complaints about ghosting and smearing on the VA panel detract from its performance.
With only HDMI, VGA, and Audio Output, the absence of a DisplayPort is a notable limitation for a modern gaming monitor.
The stand is limited to tilt adjustment (-5°/+15°), lacking height, swivel, or pivot, though it does support VESA mounting.
Best For
- Casual PC gamers who prioritize a 144Hz refresh rate over pixel density and don't play competitive titles.
- Budget-conscious users needing a large screen for general productivity and media consumption.
- Home office setups where the monitor will be VESA mounted for improved ergonomics.
- Users upgrading from a 60Hz monitor who want a noticeable refresh rate bump without spending much.
Not Recommended For
- Competitive gamers who require fast response times and minimal ghosting.
- Users who need precise color accuracy for professional photo or video editing.
- Anyone expecting true HDR performance or a high pixel density for crisp text.
- Users who need flexible ergonomic adjustments directly from the included stand.
Watch Out For
- The 144Hz refresh rate is only achievable via the HDMI port; the VGA port is limited to 60Hz.
- Multiple users have reported significant ghosting or smearing, particularly with fast-moving objects on screen, making it unsuitable for professional gaming.
- The monitor lacks built-in speakers, requiring external audio solutions.
- The on-screen display (OSD) menu has been described by users as a 'hassle to use'.
- Some users found the brightness 'quite low out of the box' and colors 'a little bit saturated'.

What Buyers Say
Many users are drawn to this monitor for its large 27-inch screen and 144Hz refresh rate at an entry-plus price point. The VA panel's contrast is frequently highlighted, providing deeper blacks than typical IPS panels. However, a recurring complaint is the ghosting and smearing, especially during fast-moving scenes in games, which can be a dealbreaker for competitive players. The basic tilt-only stand is a common point of frustration, often leading users to invest in a VESA mount. The OSD menu is also frequently cited as clunky and difficult to navigate, making adjustments a chore.
“Honestly, for the price, it's a huge screen and 144Hz is cool, but the ghosting is real, man. My eyes get tired trying to track stuff in shooters, and the stand is just a joke, had to buy an arm. Still, it's cheap, so whatever.”
Common Praise
- The 4000:1 contrast ratio delivers noticeably deeper black levels.
- The 144Hz refresh rate provides a smoother visual experience compared to 60Hz monitors.
- The slim bezels create an immersive viewing experience.
- The monitor feels sturdy and well-built for its price point.
- The anti-glare matte surface effectively reduces reflections.
- Eye care features like flicker-free and blue light filter are appreciated for long sessions.
Common Complaints
- Significant ghosting and smearing are present, particularly in fast-paced games.
- The stand only allows for tilt, lacking height, swivel, or pivot adjustments.
- The on-screen display (OSD) menu is difficult to navigate and adjust.
- The 1080p resolution on a 27-inch screen can appear pixelated or less sharp.
- HDR10 implementation is basic and doesn't offer a dramatic visual improvement.
- Lack of a DisplayPort limits connectivity options for some users.
Ownership Tips
- The single joystick button for OSD navigation can be frustrating to use after a few weeks.
- The VA panel's viewing angles, while advertised at 178°, can show some color shift from extreme side angles.
- The monitor's power brick is external, which can be a minor inconvenience for cable management.
- Achieving the full 144Hz requires using the HDMI port, so ensure your graphics card has an available HDMI output.
- The matte finish is effective at reducing glare, even in brightly lit rooms.
Frequently Asked Questions

Yes, the monitor is VESA 100x100mm compatible, allowing you to use a monitor arm or wall mount.
Is this monitor suitable for competitive gaming?
While it has a 144Hz refresh rate, the VA panel is prone to ghosting and smearing, which makes it less ideal for competitive gaming where quick, clear motion is crucial.
What kind of ergonomic adjustments does the stand offer?
The included stand only allows for tilt adjustments, specifically -5 degrees forward and +15 degrees backward. It does not offer height, swivel, or pivot adjustments.
Does this monitor support HDR?
Yes, it supports HDR10. However, user feedback suggests the HDR effect is not as pronounced as on more premium monitors.
Buying Guide
When looking at a monitor like this, you need to balance what you're getting for the money. A 27-inch screen at 1080p means pixels are bigger, so images won't be as crisp as on a smaller screen or higher resolution. The 144Hz refresh rate is a big win for smoother motion, but because it's a VA panel, you might see 'ghosting' – a blurry trail behind fast-moving objects. This is a trade-off for the deeper blacks VA panels offer compared to IPS panels.
VA Panel
VA (Vertical Alignment) panels are known for their high contrast ratios, meaning deeper blacks and more vibrant colors than TN panels. Think of it like watching a movie with really dark scenes – VA panels handle those better. However, they can sometimes have slower response times, leading to ghosting.
144Hz Refresh Rate
This is how many times per second the screen updates. A 144Hz monitor updates 144 times per second, making motion appear much smoother than a standard 60Hz monitor. It's like watching a flipbook with more pages – the animation flows better, especially in games.
FHD 1080p Resolution
This refers to the number of pixels on the screen (1920 pixels wide by 1080 pixels high). On a 27-inch screen, 1080p means the pixels are spread out more, so you might notice individual pixels if you sit close. It's like having a photo printed on a large canvas – if the resolution isn't high enough, it can look a bit grainy.
FreeSync
This technology synchronizes the monitor's refresh rate with your graphics card's frame rate. It prevents 'screen tearing,' which looks like a horizontal line breaking up the image. It's like having a conductor for an orchestra, making sure the music (your frames) and the performance (the monitor's refresh) are perfectly in sync.
Alternatives
If ghosting is a concern, look for monitors with an IPS panel and a 1ms response time. If you need sharper images, search for a 27-inch monitor with 1440p resolution or a smaller 24-inch 1080p model.
