Previously all was fine on a LED TV. When I changed channels I can see the channel info display, see the menu to change language, subtitles, Astro settings etc.

However, after I changed to a new UHD TV yesterday, none of that info is displayed anymore. To further check, i connected my decoder to a another computer monitor and same thing. It looks like the decoder has changed some settings automatically. I can still Astro & flip channels, just the decoder UI has disappeared.

I am wondering whether anyone has encountered this problem before. Thanks.

It's been given away already.
