It's possible that the chip internally always downsamples to 16-bit. We'd have to take a look at the datasheet to be sure. The chip works by taking the raw pixel information directly from the video chip, so there isn't multiple versions (that I am aware of) of the same video. In other words, if you really have your display set at 24-bit, then the video chip is sending 24-bit information to the BT869. In order for the BT869 to display the data correctly, it must be told that the input is 24-bit data. What it does with that data internally (like decimating it to 16-bit) is not clear to me. The chip, unfortunately, is meant to be a cheap and simple chip and not meant for 'serious' video use. Here, take a look at the PDF for some more info: http://www.netroedge.com/~lm78/pdfs/bt869.pdf It answers more questions, more correctly than I can. ;') Phil On Mon, Mar 25, 2002 at 07:04:18PM +0000, Magnus R wrote: > hello > I dont get it to work at all at 24bit. it works great in xfree but on > the tv its defentily 16bit. > I changed the depth to 24bit but still its 16bit on the tv output... > Have you got it to work? > > bye > Magnus > > On Mon, 25 Mar 2002 09:44:39 -0800, phil at netroedge.com said: > > > > Did you try 24 bit?
