Confusion Between Hz and response time

[liammccracken]

I don't understand the difference between ms and hz whats a good number or hz to have? overall I'm just confused if you could lend some guidance that would be great thanks!

A milliscond is a thousands of a second, hertz is a measurment of how often something happens in a second.

 

I guess you're wondering about monitors when you ask:

In a monitor hz refers to how many fps it can display, normal monitors are usually 60hz and that's fine for most people. 100-166hz is what most "gaming" monitors are rated for. If you're not a hardcore cs player then a higher end gaming monitor would just a nice thing to have, but not a must. 

 

When it comes to response time(ms) it's how long it takes for a frame to be rendered until your monitors displays it. Keep it under 10ms and you'll be fine.

The Hz of a monitor is how many times it refreshes each second. So a 60Hz monitor will refresh the image 60 times a second. Higher refresh rate monitors allow for higher frame rates to be displayed. This is mainly beneficial for gaming right now, so if you're running a game at 100 frames per second, a 120Hz monitor would be able to display all of those frames, while a 60Hz monitor would only be able to display 60 of them. Higher FPS on a monitor that refreshes frequently enough to display them will generally result in a smoother gaming experience. 

 

Monitor response times are how long it takes for a pixel to change from one colour to another. This is normally quoted as Grey to Grey (GtG), so how long it takes to go from one shade of grey to another. So a 5ms monitor, will take 5 miliseconds (0.005 seconds) to change from one shade of grey to another. High response times can result in ghosting, which is kind of like an after image when things move on the display. 

 

There's quite a bit of debate on response times and how much they actually matter. Some say that anything above 1ms is terrible, while others say 10ms and below is fine and other say different. The issue here is that response times have no standard of measurement so they're unreliable for the most part. I would advise mostly ignoring them, unless they're a pro-grade colouring monitor, which can have very high response times, most are fine for gaming (assuming that is your usage)

That's not response time, that's input delay/lag. Response time is the time is takes for a pixel to change from one colour to another and is entirely separate from input delay/lag.

so I'm getting a monitor that's 75hz 1 ms if that ok?

Incorrect.

Resposne time is the time it takes a pixel to chaneg form one colour to another. You'll usualy see manufactuers state it as a grey to grey (G to G). Generaly speaking though, look for the lowest number you can get. 1-2ms for example.

Pixel delay is one of the weakness of LCD technology, trying to get a super fast pixel response 'usualy' results in a loss in some other aspect fo the panel, such a colour reproduction or contrast.

 

The confusing between Input Lag and Response time is an all to common mistake, and it doesnt help when its so often spread around like this. it is ofc unintentional, but none the less it does not help.

 

Input Lag, is what was described in the qoute. This is the time it takes for a display to receive and then display a frame. This is usualy not the kind of information manufactuers will show in their monitor and Tv specifications. Though when you do find it, it is usualy on monitors designed for gaming. Most fo the time its up to reviewers to find out the actualy Input lag/Delay. Anything under 20ms is considered good.
