I found out, that sometimes my images are darker on my tv than on my monitor. I then, adjusted the gamma, but it takes some tweaking and it seems to be different for some of my other images.
Is there a good rule or a formula on how I could set this for future renders? This is both for still images and animation.
My guess is, that if there is a way to preset this, then it’s 1 to 1 between 2 screen types. So I assume that on yet another TV, I would again have to tweak it. Am I on the right track in understanding this?
If you have colour management turned on, and after rendering apply an sRGB profile, the hardware should then be able to correctly display the image. From there, the issue is more about correctly setting up the hardware.
Even on the manufacturer’s default settings, there is no guarantee the image will display the same on the TV and monitor, due to differences in white point, black point, brightness, contrast etc. The image could also appear differently depending on the ambient lighting.
In short, the difference is more likely because of the way the display devices are set up. You could look into using a hardware calibration device to set up your monitor, and if you use the TV as a monitor, you should be able to create a profile for that too, as it is effectively a display device, like your monitor.
These links were very helpful. It looks like I’m going to try to take my knowledge about this to the next level, so I’m looking around for a good colorimeter.
