I'm building my first PC around a Radeon 9070 and want a monitor that can take advantage of it. HDR ratings are confusing: I've seen HDR10 and HDR10+ mentioned alongside brightness labels like HDR400, HDR600, and HDR1000, plus OLED displays described as having true blacks. Is HDR600 actually worthwhile, or should I be aiming for HDR1000 or an OLED/Mini-LED panel? I'd appreciate practical advice from people who have used HDR for gaming and know which specifications matter in real-world use.

If you want genuinely black pixels, OLED is the clearest choice because each pixel can turn itself off. Standard LCD monitors use a backlight, so dark areas usually look more like dark gray. Mini-LED LCDs are a good middle ground: their local dimming can produce much better HDR brightness than OLED, though bright objects can still cause a gray or white glow around them.
Don’t rely on the HDR number printed on the box. HDR400 and many HDR600 monitors often just get brighter without having enough contrast or local dimming to make HDR look worthwhile. HDR1000 is a better target, but it still depends heavily on the panel and backlight. Check detailed reviews that measure brightness, contrast, local-dimming behavior, color coverage, and HDR performance in actual games.
For the best HDR image, choose OLED. For very bright highlights and less concern about burn-in, a good Mini-LED display may be preferable. Keep in mind that HDR support in games and Windows can be inconsistent, and some titles need calibration or fixes to look right. HDR can look spectacular in certain games, but I’d treat it as a nice feature rather than choosing a monitor based on the label alone.

That’s helpful. I’ll focus more on measured performance and reviews instead of just the certification number.
