There is no solution to this problem if you ask me. An image will always vary from monitor to monitor, unless everyone in the world sync up and everyone uses exactly the same brand of monitor and the same settings. There are software that will calibrate you monitor for you, but then everyone else will have it different from you nonetheless. So just don't worry, you work how things look on your monitor and hopefully it will look good on other people's monitors.
Yeah, I agree with Omar.
I even say, that two persons watching the same screen at the same angle and environmental light conditions, will still see different colors.
Even the same person with a different mindset (or having drunk coffee or not), but with all other factors the same, will see colors differently..
Don't worry...If you get a lot of complaints about your Renders, you should probably look into what's causing that, but otherwise...
The question mark in my mind has been resolved. Thank you for the replies.
