Overclocking a monitor

[Shock34]

I have absolutely no idea how to. I only just found out you could overclock monitors a few days ago on a youtube video posted years ago. Is it easy? Are there any requirements besides a pc and monitor?

Some monitors cannot be overclocked, and if you do it do it in small increments. Also when you overclock monitors the colors change so you will need to re-calibrate them

If you can't find any info on how to overclock a certain monitor, chances are that it's not possible.
Also, if you attempt overclocking a monitor, be sure to have both an HDMI and a Display Port cable at your disposal, as different monitors respond better to one than the other.
Also, to get the higher overclocks where it's actually worth it, you may need to adjust some more advanced values for the monitor. Hopefully you'll find a guide online with recommended values.
More than affecting colors, it can also affect the pixel response time to such degree where it's noticeable (partly because each frame lasts shorter, but also because the display has to work harder where it may suffer reduced performance).

I think overclocking monitors is actually the simplest overclock there is, since you immediatelly can tell if it works or not (if it updates refresh rate smoothly or if the display shows an error message that the refresh rate isn't supported), as well as you visually keep an eye for artifacts (frameskipping, severely reduced pixel response time). The only reason I think it's simple though is because I found a guide for my monitor with edited values available, I've never attemped editing display values on my own.

Is it an Nvidia GPU or AMD GPU you use? Or perhaps internal graphics/APU? The approach differs depending on this. Also what monitor?
