AMD renamed Freesync 2 as Freesync 2 HDR this month, with a view to better marketing and undeniably to compete with NVIDIA's G-Sync HDR.
Previously, foreign media said that if you want to pass Freesync 2 HDR certification, the display needs to meet the VESA DisplayHDR 600 standard, but AMD explained today (June 27th) that there is a deviation in the TPU.
AMD emphasized that the Display HDR of the Freesync 2 HDR and VESA are two sets of standards, the former being a year old.
In terms of parameters, Get Freesync 2 HDR-certified monitor definitely exceeds DisplayHDR 400 (mainly color gamut) but not fully HDR 600 (Mainly brightness requirements are not so high), so, there will be Freesync 2 HDR logo certification, but at the same time only meet the Display HDR 400 such monitors.
Of course, if both the Freesync 2 HDR and the Display HDR 600 are definitely the best, the latter compensates for the former's relaxation of the brightness, while the former makes up for the lack of the latter in the game refresh rate.

Finally, a brief review of the respective standards:
Display HDR 400: Supports global dimming with a peak brightness of no less than 400 nits, a global continuous brightness of no less than 320 nits, and an ITU-R BT.709 color gamut (basic and sRGB color gamut coverage of no less than 95%), and support for HDR -10.
Display HDR 600: requires screen with 10-bit processing capability, peak brightness 600nit, continuous brightness 350nit, black and white brightness response time not exceeding 8 frames, color gamut coverage 99% ITU-R BT.709, 90% DCI-P3.
Freesync 2 HDR: HDR high dynamic range, refresh rate above 60Hz, 90% DCI-P3 color gamut, etc.
