Hello.

I have a Bravia KD-49XF9005 television running through a Sony STR-DN1080P receiver. I am also using a virgin Media V6 box. I have connected to the HDMI/ARC input using good quality high speed hdmi cables.

For some reason I can access the BBC iplayer HDR test through the TV menu and the TV is flagging that it is an HDR signal, however although the BBC Dynasties series is telling me on iplayer that it is UHD this is not being picked up as UHD on the picture menu. I can access all of the UHD Netflix programs, HDR, Dolby Vision etc.

Also the 4k channels on the V6 box (BT Sport, Virgin 4k channel) are not flagging up as UHD. However I can receive a UHD signal on BBC iplayer through the V6 box. I have looked at both the TV settings as well as the hdmi settings on the receiver and have set the enhanced hdmi features to standard as setting to enhanced switches UHD off completely.

Are there any further hdmi settings on either the TV or receiver that I am missing?
