|
|
First of all hello, i am a new member in the fórum, my name is Jose and i am from Spain.
i am new in the world of calibration too but i think it is fascinating so i am trying to learn as much as i can.
Finally i decided to buy a LG OLED, and as i can see it is clearly that if i make a good calibration of my tv i can have even a better picture quality.
I have a old Toshiba LCD 32" to train, but i have some doubts.
Now i am using a Xrite i1 display pro and AVSHD 709 calibration disc plus HCFR sofware to training myself in the Toshiba.
The source is a LG BP740.
As much as i know i need to make a calibration to each source, is that correct?
In my particular case if i make a calibration and then change for example LG BP740 for another BD players like Samsung, Panasonic, Sony etc maybe the settings are incorrect in the tv, is this right?
I have an old betamax collection, is a pal system.
How i can calibrate the tv for this source? Maybe using a PAL DVD pattern as a reference?
Hope you can help me.
thanks

Each display needs to be independently calibrated. Most people do have different calibrations for each source however. That's certainly something you can try (if you display supports a per-input calibration or you have an easy way to toggle back and forth).
Most people do not different calibrations for a display for each source because it's a pain and more importantly: Because most sources will provide similar signal levels if things are set the same between sources. For example, many sources will let you choose between a 0-255 or 16-235 signal range. Set all your sources the same way and calibrate to that. I would also turn off any image enhancement features or similar in the source that could affect greyscale/colour/gamma. Just have the source send the signal "pure".

I would simply calibrate the display using your 'best' source (likely Blu-ray or similar) and be done with. You'll likely get 99% of the way there with other sources.
Good luck!

Many Thanks for help me.
i just read the grayscale calibration for dummies and i believe to understand that d65 grayscale is independent of gamut and is the same in SD and HD.
So if i can calibrate properly the grayscale, and if i make a good calibration of REC709 to my best source (in my case the LG BLURAY), PAL gamut and REC709 gamut are not much different like REC709 and NTSC so maybe i have a good start point to see the SD and my old betamax tapes whit HD calibration settings

Thanks for all.
I have a last doubt.
Is correct to say that if you see a upscaled DVD in a bluray player this source converts PAL gamut in my case in REC709 HD gamut?
