The AGON AG275UXM supports HDR10 but lacks advanced formats like Dolby Vision. 1. It uses an IPS panel with peak brightness of 350–400 nits, offering decent but not top-tier HDR performance. 2. The absence of local dimming results in less deep black levels during dark scenes. 3. It covers nearly 95% DCI-P3 for vivid colors, though real-world HDR effects depend on content optimization. 4. To enhance the experience, enable HDR10 in both GPU and game settings, calibrate display brightness and color, use HDR10-compatible sources, and avoid aggressive picture modes that distort visuals.

The AGON AG275UXM is a high-end gaming monitor that supports HDR, but it’s important to understand the specifics of its capabilities to know what kind of visual performance you can expect.

HDR10 Support – The Standard for Most HDR Content

This monitor supports HDR10, which is the most common HDR format used in games and video content. It means that when you're playing compatible games or watching HDR videos, the display can interpret the metadata included in the signal and adjust brightness and color accordingly. However, it doesn’t support more advanced formats like Dolby Vision or HLG, so if those matter to you, this might not be the monitor for your setup.

Peak Brightness and Contrast – Key Factors for HDR Performance

HDR effectiveness isn't just about format support—it also depends on how bright the screen can get and how well it handles contrast. The AG275UXM uses an IPS panel with a peak brightness around 350–400 nits, which is decent but not extremely high compared to some other HDR monitors. That means while highlights will look brighter than on standard displays, they won’t pop as dramatically as they would on a monitor hitting 600 or 1000 nits.

Also worth noting:

• Local dimming is absent, so black levels may not be as deep during dark scenes
• The wide color gamut (often close to 95% DCI-P3) helps bring out vivid colors in HDR content
• Real-world HDR experience may vary depending on game optimization and content type

How to Get the Best Out of HDR on This Monitor

To make the most of HDR on the AG275UXM:

• Make sure HDR is enabled in both your graphics card settings and the game you’re playing
• Calibrate your display for optimal brightness and color settings
• Use a source that supports HDR10—like newer PC games or streaming platforms such as Netflix or YouTube
• Avoid using overly aggressive picture modes that can wash out colors or crush shadows

It's also helpful to manually tweak the settings based on your environment. For example, in a darker room, lowering the overall brightness slightly can help with eye strain without sacrificing much in terms of HDR effect.

Overall, the AGON AG275UXM delivers basic HDR functionality through HDR10 support and decent panel performance, but don’t expect a top-tier HDR experience. It’s good enough for casual HDR use, especially in gaming, but lacks the extreme brightness and advanced features found in premium HDR monitors.
