I also have a UHD65 and am just getting to calibrating my HDR settings. While testing the settings I have noticed that the flash of the HDR overlay icon is not always consistent especially if it's already displayed for a specific source device (e.g. Roku Ultra). That despite having played SDR content in between HDR content. To make matters just a little more confusing is that when you actually have the "HDR" Display Mode enabled but move to SDR sources (Menu or non-HDR encoded content) the screen flashes and you notice the image colors change but if you check the UHD65's menu the display mode is still HDR and you must manually change it to a SDR display mode (e.g. Cinema).
I can always tell if the projector is recognizing HDR content by checking the Display Mode selection menu:
1. HDR is ONLY available as an option if the video source is HDR encoded
2. If you had already selected HDR display mode and returned back to the Display Mode selection menu HDR is still highlighted and ALL other modes are grayed out
3. Go to the projector's on screen menu Information panel. Scroll down below "Lamp Hours" and look at "Color Format". You will see:
- BT709 SDR and BT601 SDR (for any non-UHD source). The BT601 SDR is a [email protected]
source in this case (a PC).
- BT2020 SDR (for UHD non-HDR source and Display mode is NOT HDR selected)
- BT2020 HDR (for UHD HDR sources with Display Mode HDR selected)
4. Make sure that the Display mode you are using has the Image Settings->Dynamic Range->HDR "Auto". If HDR is set to "Off" your brain is going to hurt when testing HDR content because you'll never get to set HDR display mode.
I don't know if the "Color Format" can be altered by modifying an "Image Setting" so #3
's comments are true for out-of-the-box image settings. I didn't include looking at the Information panels "Color Depth" as it seems to reflect the input device rather than the source content. Example a Roku Ultra always showing 10 bit independent of the content encoded color bit depth.
