75hz 1080p 64 hz 1440p

so i have a 1440p monitor on amazon I see people say they have it at 80 hz but its able to do 75 why can I do 77hz at 1080p but only 64hz at 1440p? any tips for a reason why?

Probably something to do with the bandwith of the cables? What monitor are you looking at?

Not getting the best example of that monitor? If the monitor wasnt advertised as 1440p 75Hz then you can only accept it (or return it, like an a**hole)

@Jurrunio my point was more about it can do 75 hz at 1080p but not 1440p meaning it should be able to since it can refresh that often

In addition to this. If Op is talking about OCing a monitor. I've never done it. But have heard it is also quality dependent. Not all same monitors can OC the same.

ill understand if it cant ever hit 75 hz but why can it do it at 1080p but not 1440p

Generally smaller (in number of pixels) panels are easier to refresh faster. The best 1080p panels can do 240hz, 1440p can do 165hz, and 4k hasn't really gone above 60hz.

With monitors, the higher the resolution, the lower refresh rate they'll be able to do.

 

Your monitor's default is 1440p @ 60Hz, So you shouldn't gripe about not getting 1440p @ 75Hz.

An increase of 4Hz at the max resolution is decent. It's a bit of a lottery with the quality of the panel.

 

Monitors have a clock-rate, sorta like your Graphics card or CPU, where it determines how much information can be pushed to the panel per second. You get this number by multiplying pixels by refresh rate.

 

If you lowered the monitor to 900p or maybe 720p then I reckon you could get a higher refresh rate like 80Hz or higher.

The screen is refreshed one line at a time from top to bottom, so to refresh all 1080 lines on a 1080p screen it has to go through the lines at a certain speed to be able to refresh the whole thing 75 times per second. If there are 1440 lines and they have to be done in the same amount of time, there is less time to refresh each line, so 1440p 75 Hz does actually require faster refreshing than 1080p 75 Hz. This is called the horizontal refresh rate. Screens have speed limits on that in addition to the vertical refresh rate.

@GlenwingThank you I didn't know that and well that explains why it can do it at 1080p and not 1440p COUNT THIS TOPIC CLOSED
