Hello @djakac9,

there is a difference between 4K (UHD) and HDR.

I doubt any of these channels gets broadcasted in HDR.

Could you supply any info on where these channels claim to broadcast in HDR?

The channel TEST 2 on Astra 19,2e works in hdr mode(11024 H 3/4 23500) and the difference in the picture (the colors are much more pronounced and intense) and on the ifobar and the channel list, whether it should display information on the screen when it is in hdr mode because there is no info on the oled panel(message)

OK, so Travelxp 4K broadcasts HLG HDR, and your TV supports HLG HDR, but I think you aren’t watching Travelxp 4K on the satellite tuner on the TV for some reason, but instead via the Dreambox 900.

Does this support HLG HDR?

whether some info is required on the screen when HDR is turned on because the picture is great but I do not know if it has been switched to HDR mode in TV
