Who it fits
Good fit for
You should consider this monitor if you edit photos or videos and play competitive shooters. The 4K resolution and 99% DCI-P3 coverage ensure accurate colors for creative work. The 240Hz refresh rate and G-SYNC support provide fluid motion for fast games. The Neo Proximity Sensor helps protect the OLED panel when you step away from your desk. If you want a compact 27-inch screen that handles both professional tasks and high-speed gaming, this setup fits your needs.
Who should skip it
You might want to look elsewhere if you primarily use a single monitor for office work. The 27-inch size with 4K resolution requires you to sit close to see details clearly. If you need a larger screen for media consumption or casual gaming, a 32-inch or 34-inch ultrawide may be more comfortable. Additionally, if you are sensitive to the potential for OLED burn-in despite the protection features, an IPS LCD might offer more peace of mind for static content usage.
Verdict: This monitor delivers a compelling mix of 4K clarity and 240Hz speed for users who need both. The OLED care features and color accuracy make it a strong choice for creative gamers.
Key specs explained for this monitor
Panel Type: QD-OLED
This panel combines quantum dots with organic light-emitting diodes. You get deep, perfect blacks because individual pixels turn off completely. Colors appear vibrant and accurate without the grayish wash of older screens. This technology is ideal for gamers who want high contrast and viewers who edit photos, as it delivers true blacks that standard LCDs cannot match.
Resolution: 3840 x 2160
This 4K UHD resolution provides four times the pixel count of 1080p. Text looks sharp and clear, making it suitable for productivity tasks alongside gaming. You see fine details in games without needing to scale interfaces. When comparing ultrawide monitors, note that this 16:9 aspect ratio fills the screen differently than 21:9 models, offering a more traditional viewing rectangle for most content.
Refresh Rate: 240Hz
The screen updates 240 times per second, which is significantly faster than the standard 60Hz. This reduces motion blur and makes fast-moving scenes look smoother. Competitive shooters benefit most from this high rate, as you can track enemies more easily. When shopping, compare this to 144Hz or 165Hz models; the higher number offers diminishing returns for casual users but helps in fast-paced titles.
Response Time: 0.03ms
This is the time it takes for a pixel to change color. A 0.03ms response time is nearly instantaneous, minimizing ghosting and trailing artifacts behind moving objects. You will notice less blur during rapid camera turns in games. This spec is crucial for high-refresh-rate displays, ensuring that the fast frame rate is not hindered by slow pixel transitions, unlike slower IPS panels.
Design and build quality
The monitor measures 24.1 inches wide, 20.1 inches tall, and 6.6 inches deep. It weighs 16.4 pounds. The listing describes the color as black. This finish helps the display blend into most desk setups without drawing attention away from the screen. The physical footprint is compact for a 27-inch class device, which matters if you have limited desk space.
According to the listing, the unit includes a custom heatsink design. This component aids thermal management during long gaming sessions. Proper cooling supports the monitor’s longevity and consistent performance. The build also integrates ASUS OLED Care Pro with a Neo Proximity Sensor. This sensor detects when you leave your desk and switches the screen to black. This feature reduces burn-in risk when the monitor is idle.
The overall construction prioritizes durability and heat dissipation. The 16.4-pound weight suggests a sturdy base and internal components. You should ensure your desk or mount can support this mass. The design choices reflect a focus on sustained high-performance use. The black exterior and internal cooling system work together to maintain visual quality over time. This approach suits users who plan to keep the monitor powered on for extended periods.
Setup and everyday use guide
You connect this monitor via standard video inputs to drive its 4K resolution at 240Hz. The display supports G-SYNC synchronization, which pairs it with compatible NVIDIA graphics cards to eliminate screen tearing. This sync technology ensures that frame rates remain consistent during fast-paced gaming sessions. The panel’s 0.03ms response time minimizes ghosting, allowing you to track moving objects clearly without visual blur.
For daily use, the monitor includes ASUS OLED Care Pro. This feature utilizes a Neo Proximity Sensor to detect when you are away from the desk. When you leave, the screen switches to a black state to reduce burn-in risk. This automation helps protect the panel during long work or gaming periods. The display also employs OLED Anti-Flicker 2.0 technology. This algorithm reduces flicker by 20% compared to previous generations, providing a more stable image for extended viewing.
The monitor’s physical dimensions are 24.1 inches wide, 20.1 inches tall, and 6.6 inches deep. It weighs 16.4 pounds. You should ensure your desk can support this weight. The custom heatsink design manages thermal output during intensive tasks, maintaining performance over time. The listing notes a 3-year warranty with ARR and burn-in coverage, offering long-term security. You also receive a free 3-month Adobe Creative Cloud subscription with purchase. This bundle supports photo and video editing workflows, leveraging the monitor’s 99% DCI-P3 gamut and true 10-bit color accuracy.
Before you buy this monitor
You need a powerful GPU to drive 4K at 240Hz. Ensure your NVIDIA card supports G-SYNC for full compatibility. The monitor includes a Neo Proximity Sensor. You must keep it powered to detect when you leave. This feature switches the screen to black to prevent burn-in. You should also check your desk space. The unit weighs 16.4 pounds and measures 24.1 inches wide. It fits standard stands but requires solid support. Color accuracy is high, making it suitable for editing. However, OLED panels require care. You should avoid static images for long periods. This model uses 4th-gen QD-OLED tech for better longevity. It sits alongside other high-end options in our 1 review. You get a three-year warranty with burn-in coverage. This adds peace of mind for daily use. The included Adobe Creative Cloud subscription is valid until 2028. You should verify the offer terms before relying on it. Regular updates to the firmware may also be needed.
Check before you buy
- Verify your GPU supports G-SYNC at 4K resolution.
- Ensure your desk can hold 16.4 pounds.
- Check proximity sensor placement for accurate detection.
- Confirm Adobe Creative Cloud offer validity date.
