Well I took my PC from my room and hooked it up in the room where my TV is so that I could fiddle with the colorimeter today. I don't have a windows laptop and unfortunately the Mac version of HCFR does not do the EyeOne, so I had to pull the PC out.
Anyways, here is the results I got. Assuming the meter is accurate with LEDs, I was impressed with how well the display measured up with completely neutral settings (ISF Expert mode, everything zeroed out). After following the calibration steps from this thread
I was able to get the results even better (again, assuming the meter is accurate). Qualitatively it seems like the screen is a bit clearer now and I am happy with the result. I will stick with the settings for now and just leave it at that.
Here are some pictures of the before or stock condition:
Notice that the red primary is basically spot on, with no correction. Green is a little wide (was even wider with the TV on wide gamut setting) and blue is a little off but pretty close. All the white values fell within 10 dE except for I think the 10% IRE which was a little off. The luminance tracking seemed pretty impressive to me (especially considering the sample graphs in the directions!)
After calibrating the greyscale and RGBYCM colors here is the result. I was able to handle in the RGB levels and get all the luminance values to a dE of less than 2. Some minor tweaks to the primary/secondary colors (was not able to completely fix the blue and by extension the magenta) and the results at least theoretically are looking very good.
The gamma somehow got worse at the top end I'm not exactly sure why. But the total differences seem to be very minor from the before to the after condition.
In all a fun experiment and I'm quite happy with the display quality. Looks like this is about as good as I will be able to get it given my current equipment and it's plenty good for my needs. Heck I use the TV mainly for gaming anyways
. Sorry about all the pics for those on a slow connection.
