OLED Ultrawide Monitors With Real True Black HDR Contrast
True Black HDR is a specific VESA certification that only applies to OLED panels, because it requires the near-zero black levels that come from turning individual pixels fully off. That's different from the HDR10 or DisplayHDR 400 badges you'll see on VA and IPS ultrawides, which rely on backlight brightness tricks rather than true per-pixel contrast. If the phrase "true black" matters to your search, you're really asking for OLED, not just any HDR-labeled ultrawide.
Only a couple of monitors in this pool actually carry OLED panels with True Black certification. Everything else here is a VA or IPS ultrawide gaming monitor with a high refresh rate and HDR10 support at best, which is a real category of its own but not the same contrast experience. This guide ranks the true OLED options first, then lists the closest non-OLED ultrawides for anyone who wants the wide-screen gaming feel without OLED pricing or burn-in risk.
Picks were chosen from published panel type, HDR certification tier, refresh rate, and what recurring buyer feedback flags as strengths or weaknesses, not from hands-on testing.

What to look for
The spec that actually separates these monitors for this query is panel type plus HDR certification tier, not just refresh rate. "HDR10 support" on a VA panel means the monitor can decode HDR signal, but without per-pixel dimming or a real local-dimming array, blacks stay gray and contrast is limited. DisplayHDR True Black, by contrast, is only awarded to OLED panels and confirms the deep, uniform blacks that make HDR content look distinct from SDR. If a listing doesn't mention OLED or True Black specifically, assume it's using backlight-based HDR, which is a real step up from no HDR but not the same thing.
Beyond panel type, check refresh rate against your GPU. A 240Hz or 330Hz OLED ultrawide only pays off if your graphics card can push frames near that rate at the monitor's resolution; otherwise a 165Hz VA ultrawide will look nearly identical in practice while costing less. Also weigh OLED's well-documented burn-in risk with static UI elements (taskbars, HUDs) if you plan to also use the monitor for office work, since manufacturers note this as an inherent tradeoff rather than a defect.
