IMHO as a user this means that the "Auto" option is broken, but I bet they wouldn't see it that way.
Actually NO, the "Auto" setting is not "broken" - it is working exactly
the way it is designed to work. In fact, it works the exact same way that ALL "Auto" settings work. (But I do
understand what you're saying.)
Let me explain.
When a connected video source device (in this case, a UHD Blu-ray player
) is first powered ON, it sends a request to the TV for an E-EDID (Enhanced - Extended Display Identification Data).
This E-EDID, provided by the TV, describes and relays its capabilities and operational characteristics to the player. (e.g. I'm capable of displaying 2160p, HDR, 10-bit content.)
This information, contained in the E-EDID, then allows the UHD Blu-ray player to generate and customize its video and audio data stream output for the unique capabilities and characteristics of the TV.
The whole point of the "Auto" setting is to use this E-EDID information in order to automatically
maximizes the functional compatibility between devices without requiring a user to configure them manually
, thus reducing the potential for incorrect settings and adjustments that could compromise the quality of the displayed images.
In other words, since this TV is capable of displaying 2160p content, then that is what will be output from the UHD player when set to "Auto".
If you were to connect the player
to a 1080p, SDR TV with the output set to "Auto", then the output would match the TV and be limited to the capabilities of the TV (i.e. it would NOT try to output a 2160p HDR signal in this case).
Hope this makes sense.
What you are talking about in your quote above, is for the player to have the ability to output a native
signal to the TV - native to the content
that is. You want the player to have the ability to distinguish between 1080p content and 2160p content and to output it at the content's native
resolution without requiring any input on your part. In this case, the TV would upscale the 1080p signal as opposed to the player doing the upscaling.
I agree with you that this would be a good feature to have.
But it would not be called "Auto"; it would probably be called "Native" instead.
