Hi,
I'm trying to use my MacBook Pro to send calibration patterns to an HDTV
over a TB->HDMI cable. These patterns are to be read from the screen
using a DTP-94 and ColorHCFR, a free display calibration tool.
However, it's essential that these patterns reach the HDTV unmodified, and
as far as I'm aware OS X applies a display profile to all outgoing video
signals. As a result, the video patterns would differ from what was
expected and so the calibration would be affected.
So, first question: am I right in assuming that a display profile is
always applied? OS X seems to assign a generic profile no matter what I
do, but maybe it simply acts as a passthrough?
Second question: if I'm right and OS X always assigns a modifying display
profile to any given display, is there any way of disabling it, even
temporarily?
Thanks.
