so i recently got the koorui 24e3 and while the motion clarity is a nice upgrade (from my asus vg249, the colors made it borderline unusable. after tweaking the colors for a few days, i wanted to share my color settings to hopefully help you enjoy the monitor more. keep in mind this only applies to you, if your monitor also came overly saturated + too much orange/green. apparently from what others have said, this monitor is very volatile when it comes to display color by default. some will get very good colors out of the box, others will get unlucky and have very bad color accuracy and will need to spend time tweaking things.

monitor color settings

brightness:40 (preference, can increase if you want)

contrast 50 (contrast/gamma is more on the white/light side, but will be tweaked in nvidia instead)

r 41 (by default there is too much orange, this brings it down. even though there is an overtint of orange, this monitor actually struggles with actual orange and yellow, always comes out slightly brownish. mostly fixed with the rest of the settings)

g 36 (way too much green by default, this removes most of it, the rest in nvidia control panel to tone it down just a bit more, hard to fully remove though without ruining the other colors)

b 50 (struggles with blues, but turning this up would ruin the rest of the color scheme, mostly fixed with nvidia control panel)

gamma 1 (gamma 2 makes it too dark. although gamma 1 brings too much on the white balance side, but will be toned down in control panel section)

nvidia control panel color settings

color channel: green

brightness 47% (too much green by default, this helps bring it down so blues can come through better)

color channel: all channels

gamma .95 (helps with contrast/darks, there is still a slight white film presence)

digital vibrance: 42% (colors are oversaturated by default, reducing vibrance helps bring it more in line with natural colors. can use anywhere from 41-45%, for my case/preference 42% looked best)

hue: 7% (final thing to bring things more in line with a natural color, removes the slight pink tint)

keep in mind, this is me just eyeballing it, with another monitor for reference (that is mostly color accurate). the only way to get closer would be to use something like colorimeter, which i dont have, but if anyone wants to try and leave their settings for others to use, feel free to do so.

also keep in mind that not all monitors from this lineup come with the same colors, as ive mention earlier. according to what other people have said, some get better colors out of the box, others get worse. in my case, i got a monitor that is overly saturated and has overly strong orange and green tints that completely looks bad. ive managed to get things pretty in line after a few days of changing settings, waitng a day, re tweaking with fresh eyes, waiting, retweaking etc.

very satisfied at this point with the colors and this is closer to a 4.5/5 as a monitor now. hate the fact that i had to do so much trial and error though, but at least i got it to a very useable state from default.

obviously it all comes down to preference, but if youve used any display that is close to color accurate, it is very annoying and almost unusable to have to look at something so badly color tuned. although in this case, with how brightly orange and green it was + the over white balancing film, it borderline would hurt to look at.

hope this helps you with your settings, will update this if i end up changing anything, but things are pretty locked in at this point, again the only way id get closer is with a colorimeter or something.

(also why does the light under the monitor blink constantly when the pc is off, it's so annoying) (you can turn the monitor off by pressing the joystick in, but you have to turn it back on everytime which is also annoying) (covering with black tape is a partial fix)

(also idk what flair to use)
