L o l, I thought that’s what EDID was reporting based on all the previous posts, back to square 0. It must be hidden in the TVs firmware. I don’t recall seeing anything in service menu or ez adjust of my E7.

Since it's quite a old TV, it might not support TV-LED.
Ah that sucks. Am I missing a lot if I can only use LLDV?

What is the internal config for tmax in our C2
It's apparently 810 nits AFAIK. 990 nits for the G2.
Mine measures around 815-825 nits IIRC.

Interesting, maybe get calibration commands can tell us something. I didn’t calibrate my E7, I applied someone else’s calibration file. I’ll browse and see if there’s something there I can use on my 2017 E7 (nope I get asyncio.exceptions.TimeoutError, most likely doesn't work with older models).

Not much since Chroma Weight is rarely used in real content.

Ok thanks I'll check those out. I saw Vincent's video saying how the TV-LED is better because the colors are more accurate. But I have also seen comments here that that video doesn't mean much. Is TV-LED more accurate for the colors or does that video not matter?

Better color mapping, maybe? but I wouldn't say LLDV has inaccurate colors as long as the player doesn't have bugs (shield red push) and Chroma Weight is not used by the colorist.

The difference shown in Vincent's video is definitely Chroma Weight and the Spears and Munsil montage he used is a VERY bright grade(4000+) which is not representative of the average Movie HDR grading (0-1000nits) so indeed, his video doesn't mean much for real content viewing.

Oh good. Does the X700 have bugs like that?

Red push, no.
It has issues with EDID higher than 1000nits though but your TV is only 500nits so you're ok.

Ok good thanks, cause I saw another comment of yours saying the X800M2 having less bugs than X700 and I thought maybe I should have gone with that one.

For just DV playback, the x700 and oppo have the DT-DL TS/MT2TS rip bug which locks the player if you try to play two files in a row (quite annoying).
The X800m2 does not have this bug.

Good to know. I thought I wasted my money for a second because apperantly I cannot do TV-LED but with LLDV for real content there is no difference I guess.

@RESET_9999, from that GH link you shared I learnt how to unpack LG firmware for my TV. Currently browsing it, unsure if I'll find something relevant to our DV discussions (tmax,...).

Oh I found a dolby folder with DoVi configuration files, though there's no Tmax > 600 that I found. Those files have a lot of detailed info. Maybe not relevant, who knows :shock:

So we have only one device capable of true TV led and is the Apple TV and, of course, the UHD BD players (Oppo, Sony etc)
For Player Led (LLDV) we have more players (shield, homatics, ugoos, Firestick etc) But none of them is without problems (inaccurate colours, inaccurate EOTF tracking, inaccurate brigtness rendering etc.).
Correct?
So, BD players apart, maybe the best device presently is the ATV with Infuse.

Yes, it's either the ATV: I'm pretty sure cmv4.0 is broken and all my TV-LED measurements from the ATV were noticeably darker than the Shield and X800m2
or the Shield: Red push, lots of dropped frames, Resume is buggy, the UI is not great and also buggy.

On my end, I switched to Kodi C2 internal app with MKV and I use my X800m2 only for FEL or when the lossless audio is important (action movies).
