The Projector Central review did mention that the Rec709 colours are way over-saturated, and the greyscale measured 8500K at the 6500K setting.HI
I did spend some time to understand more about the process. Got a good hold of the basics now.
I tried calibrating again my projector and end up with same results in colour management. I'm not sure if my grey projector screen is interfering the white point of the colour management?
I tried saturation sweep and adjusted the 75% quiet good for main colours(except one colour), but 100% saturation sweep is way out.
Here is the results of my projector calibration (attached) and CIE presented:

Then i planned to check the calibration with my LG 4K TV (Just took reading no correction made):
It looks like the colour space was much accurate (i can easily correct the small errors), but gamma is bit far.
I have attached the report and CIE diagram from my TV presented below:
At least my TV colour space looks much closer to REC 709.(i can adjust and make it good for sure)

But what I'm doing wrong with my projector calibration is what I'm scratching my head now.
Some of the thoughts i have:
1. Is grey projection screen have impact on colour space? if so any special settings needed?
2. Looks like my projector colour space is not even close to REC709? Could be that the manufacturer don't support that ?? It's highly unlikely as its a latest DLP projector (Viewsonic X-10 4k).
3. I used the same laptop for my TV, which works great and so my interface should be correct. I'm using mad VR .
4. i used an user settings in projector and trying to adjust for 6500 colour temperature and REC709. All extra processing i have defeated in the projector settings.
Any advice here? Is that anything special i need to do in the settings for my projector calibration.
I did spend yesterday 5-6 hours for gamma and colour correction, but only succeeded partially in gamma correction and no luck with colour management at all, even though i have corrected some saturations.
Also, it uses an RGBB LED light source, which your meter may not able to read accurately.
