Hi,

I have a projection room with a W1090 (1080p SDR). KODI is used to access a server content via DLNA. The server running MezzMo is located in a technical room. The projector is connected to a Xiaomi Mi Box S (1th gen). I cannot get tone mapping to work.
 
On the Mi Box, there are no tone mapping settings with DV/HDR10 content. I can see these options when I disable Hardware Acceleration (Surface), but this setting must be activated for proper playing.
   
On a Fire TV Stick Lite (which is not powerful enough to properly decode UHD videos), the tone mapping settings are visible, even with both Hardware Acceleration settings activated. 

My question is simple : Which box/stick should I buy to make sure I get tone mapping settings with hardware acceleration enabled ?

Mi Box S 2nd Gen ?
Fire TV Stick 4K 2n Gen ?
Other ?

Thanks !

My question is simple :

This is really a hardware issue, and with all said baggage in the post, is less than simple given the hardware eluded. So I've taken the liberty of moving this post to the hardware forum. Suggest you avail yourself of https://forum.kodi.tv/showthread.php?tid=376035 and any advice given by users in this area.

You'll probably find you get more control on a non-Android platform - like CoreElec or LibreElec.  If you need Android for DRM streaming reasons - it's trickier.

Tonemapping HDR to SDR, and Rec 2020 Wide Colour Gamut to Rec 709 regular HDTV colour primaries, is not always that satisfactory - you often find that the HDR UHD Blu-ray converted to SDR looks worse than the SDR Blu-ray because the latter has been optimised for SDR (either manually or by post-production algorithms rather than stuff that a cheap STB can do on-the-fly)

Thank you both for your advice.

Finally, I'm thinking of buying a new projector. The tests I've made with the software's tonemapping functions haven't satisfied me (too dark, not enough contrast, burnt highlights).
