No one with a gun will be standing by your side, if you want to use one of these "inexpensive" monitors for YouTube delivery.
That is not what we're talking about when we are talking about meeting Dolby Vision minimum specs.
This only apples if you're planning to deliver for one of the streamers- HBO, Netflix, Disney, Apple etc.
All these deliveries must be done in an Dolby Vision approved facilities. That means, that Dolby representative will show up and inspect your monitor and it will be properly calibrated, if needed.
If you missing a monitor, that meets specs, you will not be given Dolby Vision approval, simple. But that was true before Covid. No more in-person traing and facilities visits, all is done remotely now.
And a couple of days ago that has changed again. Starting next year Dolby will stop certifying facilities.
Instead, they will be certifying colorists and engineers. It is all very new and details are still sketchy, but the bottom line, if you delivering for Youtube, you're good using pretty much any monitor you can afford and deem "good enough".
For proper Dolby Vision deliverables, not so much
