When connecting to a DVR, you may lose the option to change that particular option. This means that the DVR is communicating the signal scale (0-255 or 17-237) to the TV and the TV is automatically using that setting, so it would be unwise to set it differently anyway. If it's a modern DVR it should be sending the 0-255 signal flag, in which case you do not
want to use the Low setting. Low should only
ever be used if your equipment does not support the full range for HDMI. That hasn't been the case for most equipment for a good three years now, as most do in fact use the full range instead of clipping the signal.
