ASUS vs KTC Monitor Specs
Resolution clarity
The KTC H27P22S offers a 4K UHD resolution of 3840 x 2160 pixels. This provides significantly higher pixel density than the ASUS XG27AQDMGR, which is limited to 1440p (2560 x 1440). For tasks requiring sharp text or detailed imagery, the KTC panel delivers finer detail. The ASUS monitor uses a QHD resolution, which is standard for many gaming displays but lacks the crispness of 4K. If you prioritize visual fidelity and sharpness for productivity or high-resolution gaming, the KTC specification is superior. The ASUS option is adequate but less dense.
Panel technology
These monitors use fundamentally different panel types. The ASUS XG27AQDMGR features a WOLED panel, known for true blacks and infinite contrast ratios. It is described as glossy, which can enhance color vibrancy but may reflect more ambient light. The KTC H27P22S uses a Fast IPS panel. IPS technology generally offers wider viewing angles and consistent color reproduction, though it typically has lower contrast than OLED. The ASUS OLED provides better black levels, while the KTC IPS offers a different viewing experience. Your choice depends on whether you prefer the deep contrast of OLED or the reliability of IPS.
Refresh rate speed
The ASUS ROG XG27AQDMGR boasts a higher refresh rate of 240Hz. The KTC H27P22S runs at 160Hz, with support for 144Hz. For competitive gaming, the ASUS panel can display more frames per second, resulting in smoother motion. The 80Hz difference is noticeable in fast-paced titles. Both monitors support high refresh rates suitable for modern gaming, but the ASUS specification is objectively faster. If your workflow or gaming habits involve rapid movement and you want the highest possible frame rate, the ASUS monitor has the advantage in this category.
Response time
Motion clarity is determined by response time. The ASUS monitor specifies a 0.03ms gray-to-gray response time. The KTC monitor does not list a specific response time value in the provided data. OLED panels typically have near-instantaneous response times due to their technology, which helps eliminate ghosting. The ASUS specification of 0.03ms is extremely fast. Without a comparable figure for the KTC, the ASUS has a documented advantage in response speed. This spec ensures smoother transitions for fast-moving objects on the screen, particularly beneficial for action games.
Connectivity options
The KTC H27P22S provides a robust set of ports, including two HDMI 2.1 connections and two DisplayPort 1.4 outputs. The ASUS XG27AQDMGR data does not specify its connectivity ports. HDMI 2.1 is crucial for next-generation consoles and high-bandwidth PC connections. The KTC specification allows for more flexible cable management and device pairing. If you need multiple high-bandwidth connections, the KTC offers clear, listed options. The ASUS connectivity details are absent from the data, so we cannot compare port variety or version numbers directly.
Which monitor fits your needs
Competitive FPS gamers
The ASUS ROG XG27AQDMGR features a 240Hz refresh rate and a 0.03ms response time. This combination ensures smoother motion clarity and eliminates ghosting during fast-paced sessions.

Viewers wanting deep blacks
The ASUS model uses a TrueBlack WOLED panel that delivers perfect blacks and infinite contrast. This technology enhances HDR performance and color accuracy with a Delta E under 2. The 0.03ms response time further ensures that fast-moving scenes remain crisp. You get a premium viewing experience with superior contrast compared to standard IPS displays.
Users needing connectivity
The KTC monitor includes two HDMI 2.1 ports and two DisplayPort 1.4 interfaces. This connectivity allows you to link multiple devices easily.
