[QUOTE="David J Robinson, post: 455164, member: 197198"] Yes, this is a problem I reported to Humax a long time ago, of course they have done nothing about it. :mad: Actually there are 2 faults, firstly it puts out PC levels (black = 0, white = 255 referred to an 8-bit signal) instead of TV levels (black = 16, white = 235). Hence the brightness is too low and the contrast too high. This is one reason why I feed it through my DVDO scaler, which has tweaks to take this error out. The second problem is the 'radio contrast bug' where selecting a radio channel causes the contrast to go even higher causing clipping of whites and blacks (because as noted above the signal is already at maximum so there is no headroom). There is a workround for this bug: select a radio channel, then cycle round the display settings on the V-FORMAT button. The radio contrast bug is then fixed and will remain so as long as mains power is not switched off. :rolleyes: Note to mods: it might be worthwhile to change the title of this thread to the actual model number HDCI-2000, then it will come up in a search. :cool: [/QUOTE]
