It says it has HDR10 and HDR400. Which is it? null

HDR 400. It is mediocre and i do not recommend using it.

It's both! The LG 34'' UltraGear™ 21:9 Curved WQHD Nano IPS 1ms 144Hz HDR Gaming Monitor with G-SYNC® Compatibility, Model # 34850-B is a VESA DisplayHDR 400. DisplayHDR is the open standard for HDR quality and performance and only displays that meet all the specifications may carry the DisplayHDR logo. If a monitor claims HDR support without a DisplayHDR performance specification, or refers to pseudo-specs like “HDR-400” instead of “DisplayHDR 400” it’s likely that the product does not meet the certification requirements. Often, we see the question of how to compare HDR10 and DisplayHDR. Which is better, and why? The answer in this case is very easy: DisplayHDR is better, but this is a little tongue-in-cheek because they aren’t really the same thing. DisplayHDR is a performance spec that measures different aspects of HDR quality, including luminance, color gamut, bit depth and rise time. HDR10, on the other hand, is a protocol, which is how HDR data is represented in a format that is understood by the GPU and the display. Other protocols you may have heard of are HDR10+, DolbyVision, and Hybrid Log Gamma (HLG). If you really wanted to compare HDR10 with the alternatives then it should be compared with these three other protocols for HDR. However, to make this very simple, HDR10 is the de-facto standard used by all HDR devices. Many devices support more than one protocol, but more than 99% of devices support HDR10 – so this is the protocol that provides the most extensive interoperability with other devices. Windows only supports HDR10 for the output from a GPU to an external display. While HDR10 is a protocol, and DisplayHDR is a performance spec, one of the fundamental requirements of a DisplayHDR certified device is that it supports the HDR10 protocol as a foundational minimum requirement. Hence, it’s fair and accurate to say that DisplayHDR is better than HDR10, because it includes HDR10 and then adds further requirements beyond that! The DisplayHDR specification for LCDs establishes distinct levels of HDR system performance to facilitate adoption of HDR throughout the PC market: DisplayHDR 400, DisplayHDR 500, DisplayHDR 600, DisplayHDR 1000, and DisplayHDR 1400. All tiers require support of the industry standard HDR10 format...^IFV
