Comparing the original 1000 nit waveform representing the grading monitor to a 500 nit clipped waveform representing the consumer television
How much of a problem this is really depends on how you choose to grade your HDR-strength highlights. If you’re only raising the most extreme peak highlights to maximum HDR-strength levels, then it’s entirely possible that the audience might not notice that the display is only outputting
800 nits worth of signal and clipping any image details from 801–1000 nits because there weren’t that many details above 800 anyway. Or, if you’re grading large explosive fireballs up above 800 nits in their entirety because it looks cool, then maybe the audience will notice. The bottom line is, when you’re grading for displays that are only capable of ST.2084, you need to think about these sorts of things.
Monitoring and Grading to ST.2084 in DaVinci Resolve
Monitoring an ST.2084 image is as simple as obtaining a ST.2084-compatible HDR display and connecting it to the output of your DeckLink 8K, DeckLink 4K Extreme 12G, or UltraStudio 4K Extreme.
TIP: If you’re monitoring with the built-in video scopes in DaVInci Resolve, you can turn on “HDR (ST.2084/HLG)” in the Waveform Scale Style settings in the Scopes option menu, which will replace the 10-bit scale of the video scopes with a scale based on nit values (cd/m2) instead.

Setting up Resolve Color Management to grade for ST.2084 is identical to setting up to grade for Dolby Vision. You’ll also monitor the video scopes identically, and output a master identically, given that both standards rely upon the same PQ curve.
Connecting to HDR-Capable Displays using HDMI 2.0a
If you have a DeckLink 4K Extreme 12G or an UltraStudio 4K Extreme video interface, then
DaVinci Resolve 12.5 and above can output the metadata necessary to correctly display HDR video signals to display devices using HDMI 2.0a when you turn on the “Enable HDR metadata over HDMI” checkbox in the Master Settings panel of the Project Settings.
The Enable HDR metadata over HDMI option in the Master Settings panel of the Project Settings lets you output HDR via HDMI 2.0a
