Heads up you guys! I made a post just like this before, but man, I am blown away! This is slightly off-topic, but I'd thought I'd share in case it helps someone out!
I decided to test my monitors separate presets out recently, after playing R&C on the Pro, and discovered a whole new world of color. I tried out the "game mode" on my display, which is something I've never done, thinking that it would just un-sharpen the image like a TV would do. What I wasn't prepared for was the sudden blowout of color; color that was seemingly non-existent on the standard mode for my display. The weird part is that I never thought I was missing color before, and the game mode actually is kinda how I remember the games looking! Now, when I switch back to game mode, everything literally becomes gray and boring. Right after my discovery, I immediately decided to seek out anything that would prove that the image was just getting over-saturated, but found no proof when using various tests. Some colors even remain the same when switch between the modes, so I thought about this: What if the game mode on my monitor kills all presets on my screen and allows games to use their own "pallets" in a way, as if the standard mode's color presets conflicted with the games' presets. That is just some totally stupid theory of mine though; I don't actually know what makes the game mode different!
Anyways, I took 2 pics of Hitman with one shot being the standard mode, and the other the game mode. I think I need to decompress after making my discovery. I have been playing game on standard with no issue for 2 1/2 years, but now it's impossible to go back ;_; And like I said before, the standard mode never looked bad to me!
The reason why I made this post was to hopefully have some people dig into their displays and take the time to make simple or complex calibrations! Seek out ways to get the best out of your screens (especially new buyers of those fancy boy 4K screens!)
