Yes, I only meant for Display 2/LT. I have no experience with i1 Pro... yet.

(still not sure what to do)

Yes, you do. I use a female to female straight serial cable.

Make sure you have everything shut off when fastening the connector to the TV's serial port.

Yikes, I wish the instructions that come with ControlCAL were a bit more explicit in terms of such basics, like hooking it up. OK, I'll have rummage in the attic to see if I have a female serial-to-serial, otherwise its another trip to Radio Shack.

I am re-measuring as we speak, and things are looking a lot better in terms of the readings. With contrast set to 33, I am measuring 156 cd/m^2 (or about 46 ftL). This
seems more in line with what you were saying earlier. If I reduce brightness down by 3-4 notches, I get the 100% IRE window measurement to be around 39 ftL.

Interestingly, the gray scale really flattens out at the low end if I keep the contrast at 33 or so. Otherwise, things get a bit messed up at the low end.

OK, gray scale looks amazingly flat and RGB levels are all very close all the way from 10 to 100 IRE. The CIE chart looks a little better than before, with all primaries very close (and secondaries as well).

Get ready for the surprise! The gamma curve is .... still messed up! It looks a little bit better than before, but not by a lot. It varies from near 1.1 at the high end to > 2.5 at the low end.

Any suggestions? (I need to get ControlCAL working, of course).
