I've just updated to 1239 firmware on my KS9500. I have a Roku+ and wonder if there is any way to test the HLG, given we don't have Sky HLG yet in the UK?
Use a websocket client to see if the Sky Q box sees an HLG enabled TV. In a websocket client, type ws://192.168.0.xx:9006/as/system/status where 192.168.0.xx is the IP address of the Sky Q box
Should see an HDMI section like this - so just check if "SinkHLG is true.
So i've just installed FW1239 on my KS7000 and checked the Sky Q box using the websocket client and I can confirm:
We finally got the fix! Just need Sky to launch HDR now!
Meant to post this earlier and some will be aware, however seems will be a while we have a further wait before we can enjoy SkyQ HDR in the UK. Apparently other priorities at the moment (some detailed in this article), however many will not think other offerings are as important (even if not everyone is interested in HDR).
It turns out Hdr with be coming to Sky Q Boxes from 27th of May, so shorter delay after all. Will be using HLG for some nature programmes and will follow later on Sky original Shows. However it seems the older 1TB boxes will not be compatible, though the rest should be fine. Reported on a few sites but has not yet been the fanfare of an official announcement.
