anfield, respect

Anfield, I'm using Xrite i1 with ColorHCFR on my projector. While doing greyscale calibration, I found out the Red too high in the original setting. I have to adjust the Red and Blue (RGB Gain/Offset) to get the 6500K target. The RGB post calibration looks OK but the Gamma is about 1.9 instead target 2.2. Is there anything missing here?

Thanks for grand sifu help.

Original setting:
display mode = cinema
degamma = film

New setting;
display mode = cinema
degamma = video

Is that always tunes with R/B instead of G (RGB gains/offset) in greyscale calibration? In my case, I cutdown R gain a lots (-22). Not sure it will cause the color composition to off red? I'm not able to do Color calibration due to HD-65 limitation of CMS.

The lamp is about 200hrs (STD mode). Yes, I'm using i1 Display LT, the affordable version

Display mode = Cinema/Bright/Photo/TV/User.

Degamma = Film/Video/Graphic/PC. I tried Film before but giving unstable D65 across IRE. Will try PC mode as you suggest.

BTW, I set ZERO both Brilliant Color & True Vivid setting. Image AI = Off and Color Temp = Medium.

Would give that a try. Thanks.

Anyone else doing own calibration? It is a good platform to exchange idea

Anfield & Gang, my first calibration on 508XG. Any suggesting for further improvement is most welcome.

At first, I was surprise to see the Gamma curve , too good to be true on the original setting. Until I realized the RGB and Color Temp were quite off.

The whole calibration process took so long (~3 hrs) for newbie like me. At one hand look for how-to procedures and on other the hand try to familiarize the software. But the whole learning process is fun and rewarding. Better do it at late night so that no one is ka-ka-chau-chau. I really recommend AV enthusiasts to try on this, either DIY or pay professional calibrators to do it. Imaging the significant improvement you can get from the existing hardwares just with a small price to invest versus your HT investment cost. Now, I'm realize for almost 30yrs, I am looking at something off the standard

On the CIE curves, I found the R & G points slightly off from target. Already tried on the CMS setting and still cannot get the (x,y) on the dot. Any suggestion?











Note:
a) Meter: Xrite i1 display LT.
b) Software: Color HCFR, Color space standard: HDTV-REC 709
c) Test disc: AVS HD 709
d) Left graph with original settings and right graph with new settings.

Wow, you are keng chau. Yes, the original with Color Space 1 and the new with Color Space 2. I found out the Color Space 1 too much Red and need to cut a lots during Grayscale calibration.

If don't adjust the CMS too much, how to get the (x,y) for the Primary & Secondary colors?

Attached is the chc files. Thanks

Bro Anfield, thanks for the sharing.

Welcome to the club . Great to see more kaki into DIY Cal.

Be ready to poison by master Anfield.... he he

What meter you are using?
