Does overclocking Hz make a differance?

[Nahiri_Menet]

I recently found out I can overclock my display in the Nvidia control panel, so I messed with it and got my 60Hz to run at 75hz, but does it make much of a difference? For me it feels smoother but I just wanna know if it does anything. Any response welcome, thank you in advance!

It'll display things slightly faster. It doesn't really hurt anything, so there's no real reason not to do it.

I've been running both my monitors at 75Hz for years.

 

For some games, it makes an objective difference. In Destiny 2 for example, there are a number of in-game elements that are tied to framerate. Historically, there was even a gun that had its damage tied to framerate, leading to higher framerates dealing more damage.

 

In everything that isn't a specific scenario in a game, you'll mostly just enjoy an overall smoother display and being able to see things ever so slightly sooner.

Doesn't this degrade image quality, induces ghosting etc, as the panel isn't designed for that clock ?

Do your games run at 60+ fps?  If so, then you get a smoother/better experience as they're running at 75fps visually.

 

It's subjective as to how much this really is noticeable by you though.

This can be an issue. I have a panel that I tried to OC to 75Hz and the level of ghosting wasn't worth it for me. Ironically, the panel had an "overdrive" setting (probably so it could advertise 1ms^TM response times) and even at 75Hz, the overdrive setting resulting in horrific levels of inverse ghosting that looked even worse.

 

The only real risk to this is that it could, in theory, damage the monitor. Just like with any overclocking, running something out of spec comes with a degree of risk. Monitors generally are passively cooled and designed to be so, and if it's overclocked, this can result in overheating - just like any overclocking. It's probably fine, but I feel like that caveat should be mentioned.

Yeah, it mostly depends on the panel. Some monitors are also designed to run at 75Hz out of the box, but because they don't run at 75 by default, people just don't find out about it until they go poking through custom resolutions and find out it's an option.

If a panel is designed to run at 75hz, then it should run fine with no issues.

 

The biggest damage from overclocking is typically that the monitor will die a little faster, but something like a 10-15Hz increase shouldn't hurt too much if it's a half-decent panel. Basically the same as any other component.

Image quality maybe, but usually no. As long as it's still keeping the same settings the image quality should be fine, but some screens can only reach higher refresh rates with the color depth turned down or chroma subsampling, which can cause small quality regressions. Even then the quality difference might be worth it for the higher refresh rate, that's for the user to decide.

 

Ghosting is also a maybe, but I think it's more likely than quality issues. This really depends on the panel. I haven't seen it personally, but multiple friends have had major ghosting with overclocked screens.

 

If neither of those issues appear, it's probably fine.

assuming that the display can process that signal at all.

 

some (cheaper) displays really dont like trying to run faster, my most extreme example was a TV that ran with 2 seconds latency if the input signal was anything else than 59.95Hz.

And if the cable actually can go above 60. Not all can.
