Are there any good tutorials for calibrating TVs/Porjectors WITHOUT .icc profile

[FowD8]

I tried looking around, but pretty much EVERYTHING that i’ve found only explains how to calibrate using the .icc profile generator. i’m trying to calibrate a projector that isn’t connected to a computer, but I have no clue where to start on what to change in the TV settings to properly calibrate. Like I’ll generate a measurement report but I have no clue what to do with those measurements to know what to change hue/contrast/brightness/saturation/RGB for all of the above. my projector has a ton of settings to really tune everything, but i don’t know what to adjust to get the results i’m trying to trend towards

Ue DisplayCAL’s cousin called “HCFR”, seek latest build from Arthur Lieberman.
Set TV on custom mode or whatever is labeled by vendor, the OSD mode with access to RGB gian (white) and 10-20point grayscale (grey color) and CMYRGB 6 axis control for simulating smaller gamuts.

set white and gamut boundaries and 10ppoint greyscale using the presets in HCFR. It’s like Calman.

Remember to match levels on device and software. You can use a raspi for patterns.

thank you,  this is really useful info to get me going in the right direction. i might have additional questions as I get more into it. would this be the right place for those questions related to HCFR calibration, or is there a better place for me to ask (since this forum is supposed to be for DisplayCAL)

but i’ll def start playing around with it tonight, thank you

There is a thread on AVS Forum, sub forum Display Calibration. IDNK if the current HCFR developer writes there:

https://www.avsforum.com/forums/display-calibration.139/

There is some “commercial activity” by CalMAN/Lightillusion developers, but one you accept it you can ask whetever you need.

Thanks for the advice, was actually able to get a pretty decent white balance result

I’m mostly having trouble figuring out how to play around to correct the RGBCMY tuned in, i have options to tune Hue/Saturation/Brightness for all 6 colors (as well as a “flesh tone” option for those options as well?) but having trouble figuring out what to move around to get a better delta, i kind of move things up and down randomly for say, green, trying all the green options and it kind of gets to a smaller delta, but not by much

Run a 1000 patch verification after you set primary colors to see how the TV performs overall.

You may get primaries correct but inside the gamut may look bad. So you’ll have to make compromises. It’s better to pay attention to inside the gamut instead of getting 100% saturation correct because most video content isn’t always at 100% saturation.

So tune the display that gives you overall lower delta e. And pay attention to like skin tones, we notice those more when its off.
