Samsung LCD LNxxA950 series – notes

Greetings

I had a chance to play with one last night. Interesting set. Client was using shared settings from someone else on the forum and boy was that image blue … even in Warm 2. The auto color gamut was actually close to 709 with yellow being slightly oversaturated and outside the triangle.

Using a mix of both what Mike Woods has told us as well as good old experience with the samsungs, the results were interesting.

The expert mode was turned on first with the cal-night and cal-day modes and I tried the calibration there but quickly realized that the TV could not be properly set up there as the grayscale controls simply did not have enough range. The dark end was changing color to green … ugh. I abandoned this mode and went back to the normal service mode calibration of the movie mode in the TV.

The cal-night and cal-day modes stayed so that was an initial surprise. Two more place holders similar to movie mode in the TV.

The Smart LED stays on in the movie mode SM so you have to calibrate it there. Worked out fine. Lots of range and the grayscale came in nicely although the dark end was going green again. I kept the dark end a bit more to the blue side. Calibrated the Warm 2 mode … and them proceeded to copy those numbers to normal, warm 1 and cool 2 locations. This transfers the calibrated grayscale over to the Standard and Dynamic modes of the TV and gives the client more choice for other modes.

Dynamic – Day mode (use color temp cool 2 or normal … as cool 1 is not calibrated)
Standard – Night Time with lights on mode
Movie – Night mode.

Cal-Night became the Cable TV mode for night
Cal-Day became Cable Day

Inputs have separate Color space memories so write down the numbers and prepare for lots of copying.

The CMS actually calibrated very well and was put on the 709 nicely matching the brightness values too. Problem is … the image then looked undersaturated for color. It looked like the color was about 5 to 8 clicks too low now. So watch out for this. It might be attributed to the viewing angle we were at as this person had the TV on a high fireplace mantle and the TV was not tilted down at all.
