Thank you very much for answering my questions... I have gone ahead and done the HDR and the SDR adjustments. I am a noob at this, but I am very happy with the update and the settings, the image looks very nice. The blooming is indeed much better than with the G!
Some issues I have come across so far.
****EDIT: Yet to replicate sound loss, but no solution either*********
The sound loss happened during settings adjustments on TV (antenna), I am not sure if adjusting the settings triggers a bug but that is how it happened to me. Restarted the TV and it worked again.
Solution: Nvidia Shield was going to sleep after 20 mins of inactivity and turning the TV off. There is a setting in the nvidia settings CEC that allows it to go to sleep without turning the TV off.
-TV turned off by itself.
After I restarted the TV, I went back to do some more image setting adjustments when I was in the last setting and finished it just turned off for no reason at all.
I do have a Denon 1600H receiver connected via eARC, I am not sure if the powering down is happening with something to do with eARC. Before updating to the H the TV turned off by itself whilst watching Netflix, which was on the firmware the TV came out of the box 2550 leading me to think it is not a H firmware issue but something else.
If anyone has a suggestion or fix for these issues could you please let me know.
