Tv calibration what you using
Discussion
OK, for anybody curious about calibrating colours and white balance all I can say is its very much worth it. Its night and day how much nicer it is to watch tv or movies with the warmer colours and the image looks all natural. Also the fact that all material is made to a spec and thats the spec you're after.
Anyway I have done two different Epson projectors and a couple of TV's. I also use the colormunki display. In case you didn't already know you will need a test pattern disc. I use Spears and Munsel on Bluray. I also use the PS4 as the source.
Here is the guide that I used and it starts off quite heavy but be patient.

Now after you have set brightness, contrast, sharpeness etc you will be ready for the greyscale. For this you use the white pattern. 0% ire as its called is black. 100%ire is white and every 10% inbetween are shades of grey. With the program your objective is the use the correct pattern at the correct time and use the tv's white balance to correct the Red Green and Blue of it. On the bottom left of the hcfr program you will see how much of each colour is showing in percentage. Adjust each colour up and down so they read 100%. the closer you are the more accurate your D65 white balance will be. After doing each ire you need to go over it again because they will change as they affect each other. After you are happy with the greyscale you move onto the 6 colours. Red, Green, Blue, Yellow, Cyan and Magenta. The process is much the same. You only use 100%ire with these. In the guide it tells you to aim for specific coordinates which is correct but to get there is simple. The same bottom left Red, Green and Blue bars showing percentages will work again. Use the colour management on your telly to adjust the colours to get them bang on 100% each.
Now if you think once you've done that you are finished then you are not. Altering the colours will have affected the white balance so go over and check it again. Then, recheck the colours. Then recheck the white balance etc.. each time you will perform minor tweaks until the figures are bang on. All I can say is my epson projector is bang on colour and white balance wise. However my gamma is poor most likely caused by me using a white screen. My sister uses a grey screen and her gamma is much better. Gamma as I understand it it is how different the white and black are from each other and in a perfect world it would be on 2.2
I hope this helps you and anybody else thinking of doing this.

cheers for that well so far its frustrating! adjusting the rgb at the different levels is fine until 50 and 60ire even if i go say plus 50 in the red it may have only crawled from 98.3% to 99.2% so im still ending up with a deltaE of say 6 yet below that they are all a deltaE of 0.1-0.2
wish that guide actually talked more about available lcd controls rather than projector and crt

I know what your saying there. Every tv has different controls. I have the Samsung ks7000 tv and using the 10 point white balance I could not get it at all but with the 2 point I got it fine. The two point uses 30% and 70% ire. The principle is the same for all types of monitor. I don't remember if the guide says it but green is the limiting factor because it is the least made colour. So it is near impossible to raise. Blue is the highest, so on some guides I've read or watched it is something to consider that you bring the red and blue to match the level of the green. But, I've not had to do it. It is frustrating and time consuming. You could look at things like skin tone setting, gamma or whatever your specific telly has.
