I bought a Bush FreeSat HD receiver a few years ago and have always noticed a problem with the picture it produces - the EPG and any Now/Next/Programme Info and notices like Mute and Subtitles that come up have got a fine black and white levels and full contrast for the display in question... but the TV channel that is displayed always has just a dark grey background when it's meant to be black, like the picture has a lower contrast. This has varied only slightly from display to display that I've tried and it also varies depending on whether the Bush or the display is turned on first, but the picture contrast is always dark grey rather than black. Please advise about how to fix this, as it is really rather unpleasant to try to watch TV that looks washed out. I have tried changing the brightness and contrast on the displays I've tried it on to compensate, but it is always there, and what's more, the Sony Blu-ray player I also use looks fine on it, and I wouldn't want to change b&c each time, especially as I'm using an HDMI switch. Can anyone help me? Or at least advise me on a better model of FreeSat HD receiver?
