today i see that my 55mu7000 (2017) (Holland) updated 1280.5 without permission for automatic update. i can't see any difference om my tv. i don't know what is the changelog. anyone ?
Here you can find changelog. They update it in first post when there is new software.
I dont think the MU series will ever get true HDR10+ via HDMI as it needs HDMI 2.1 version and the hardware is only equipped with HDMI 2.0. Even the GTX10 series GPUs are not HDMI 2.1 certified, hence, has no hardware support for Variable Rate and Dynamic Metadata protocol over HDMI.
The Media Player Classic, using the madVR renderer was able to detect different hdr metadata from a movie file with HDR10+ and treated it as separate video stream. It was able to send the HDR metadata over HDMI 2.0 and the TV seamlessly switched according to that hdr metadata..
Maybe its not a real HDR10+ but just an on-the-fly hdr adjustments - which samsung attempts to market as updated support to HDR10+. It is also a bit noticeable when the TV tries to adapt to the new HDR metadata. Just open your TV's profile on madVR and check "send hdr metadata to display" or something option.
The best possible HDR10+ support could be from a media file directly played on the TV over network/usb. thats the only thing i can think of that should allow the tv to support hdr10+.
Got the notification this morning, 50MU6300 updated to 1280.5 and the only thing I've noticed is they added Disney+ to my apps and also installer Mccafee antivirus again 😑😑 apart from that no major change 🤷🏻♂️
