How did you set the HDR10 flag when doing your calibration?
I just picked up a P65-C1 a few weeks ago, and my coworker has a P75-C1 (and talked me into buying a new TV because of it), and we are both interested in calibrating our sets. Our current plan is to pick up a i1Display Pro and use HCFR for the calibration. I was thinking to either use my Chromecast or the built in casting to the TV. I saw you post earlier that the built in casting doesn't currently work right. So I am thinking that using the Chromecast is my best option. The Chromecast I have is fairly old and the stick kind rather than the circle, would that make a difference in the integrity of the pattern to the screen? And if I were to pick up the Chromecast ultra, would HCFR be able to cast with the HDR10/DV flag to put the TV into those modes for calibration?
Last question, if the issue(s) were fixed for casting to the internal TV cast interface, would that be the pseudo holy grail of being able to just use any computer with the meter plugged in and calibrate both SDR and HDR without having to worry about the pattern/signal being correct on the screen? I know the idea is to use whatever source you watch from in order to put up the patterns for calibration. I just stream all my content or game on PS4 Pro, so thats why I have been planning to go that route rather than burning a DVD/Blue-ray.
Thanks in advance!
HDR10 is supported in my latest build of HCFR, look at this post: HCFR - Open source projector and display calibration software
I think that any Chromecast should work, but I haven't tested it with the first gen devices. I only have the round 1080P one (gen 2). I know that HCFR works with it and with my Vizio (as in it finds it and connects to it). HCFR sends images rather than video data to the Chromecast, therefore when you use the built in Chromecast in the display, the video look up tables (LUTs) are not loaded, and changing calibration values in the menus doesn't affect the image and readings. I haven't tested it with the recent firmware versions, though, so maybe things changed, but I doubt it. This also means that a CCU won't help to get HDR10 working from HCFR. Currently the only generators that support HDR10 are GDI and GDI (no background).
In theory, casting a video stream, be it SDR, HDR10 or DV should have the most neutral results, because there is no influence on the data displayed by inaccuracies of external devices.
So it would be the most accurate for streaming content, and inaccuracies of different HDMI devices will simply carry over as is and will not be affected by the 'offset' introduced by the source device you're calibrating with. On the other hand I think that since you're not going to be performing a professional calibration, the errors introduced by the PC or a player will be negligible or marginal at worst anyway. The i1 Display Pro is great, but it's not a reference spectro and not a high-end colorimeter.
