Monitor Refresh rate vs it's pixel response time

[Agentak74u]

I am planning on buying a 144hz monitor (I never tried anything above 60hz), but while extensive searching I got something confusing me and I didn't find any article or something about it; does the pixel response time make a refresh rate to be "true or fake" and I mean by a very small margin +-1ms (i.e 144hz require a 6.9 response time and high end monitors range from 10-4ms), so does it matter if a monitor achieve a 144hz with a 7.5ms and the other with a 6.5 Ms ?will even a 0.5ms increase over 6.9ms will make 144hz feels choppy or bad in anyway?

P.S: I am only talking about IPS monitors

Pretty good article that mostly explaines what you're asking

Monitor Refresh Rates: Why higher isn't always better

We've created this refresh rate guide, so you're well prepared for the next time you're looking to buy a gaming monitor.

In my personal experience if you're at least averaging 100 FPS or higher the experience feels pretty good but at least for me not all games benefit the same... Shooters I prefer 120hz or more but for something like Witcher 3 80fps is more than enough. So as long as the monitor can handle that you're golden compared to 60hz.

My only other recommendation is buy a good one Mid tier or lower ips can have a ton of issues with backlight bleed and all ips can have a certain amount of glow making dark scenes look grey.


This is currently my favorite ips monitor

Yeah thank you dude but I already read the article but I didn't got what I want.
And I was going for the aorus until I saw the response time which is pretty high compared to other options within the same price group (especially considering it's a freesync monitor) so mostly I am going for Asus pg279q or mg279q unless I saw something better

I went through 3 PG279Q all had terrible backlight bleed I ended up settling on the TN variant as it looks about 95% as good and doesn't have that issue. The MG I have no experiences with. It's been a couple years though so maybe Asus has sorted that out.

Asus refreshed it with the PG27QZ but that has the Same response time as the Aorus of 9.3ms vs 7.6ms for the old model

Higher refresh rate means, less motion blur and better for your eyes long term. There is a new monitor which includes low motion blur + freesync together and yet is 155hz 27 inch, 32 inch 144hz. I would buy that one, matter of fact i will buy that one when is out, the only downside is you cant have it with hdr.

"The ELMB stands for Extreme Low Motion Blur ".

ASUS Announces TUF Gaming Monitors with ELMB-SYNC ASUS has announced a trio of new displays from their TUF Gaming line, with 27-inch and 32-inch models each

I believe it will not be expensive. Probably around $400 for the 32 inch.

so does it matter if a monitor achieve a 144hz with a 7.5ms and the other with a 6.5 Ms ?

Yes because 7.5ms is higher than 6.94ms (the required average response time for 144Hz). You MAY see slight ghost on monitor. But if you are talking about 6.5ms vs 5.5ms then it should be no for normal operation. But it is meaningful for any form of blur reduction technology such as ULMB , ELMB or DyAc since every ms help reduce strobe crosstalk.

will even a 0.5ms increase over 6.9ms will make 144hz feels choppy or bad in anyway?

Like I said before You MAY see slight ghost. Not everyone is sensitive to ghosting.

Yeah man that is exactly what I was looking for, thank you !
And yes I am only asking about these monitors above 6.9ms and I don't care about pixel response time as long as it's below 6.9ms
But how I can tell if I am sensitive to ghosting or not since I've never tried something above 60 hz :/ , but in 60hz I find it very unpleasing to my brain and kinda hard to keep tracking of objects when I move my mouse in fps games

You more or less answered your own question. If you are happy with the image that your display provides than carry on and be happy with what you have. If you see an improvement from a display you're looking at getting and you like it more, go with that and be happy. It's all about personal preference and use-case scenario. Everyone has different eyes and perception of vision. What is great to one person may not be good for another and vice-verse.

For example, I personally have 144hz dual displays, but only run them at 120hz. This is because I can not tell the difference above 120hz and the math works better for some programs that need a frame time that is a multiple of 30.

Here's the real story with pixel response times - note I just picked a random high refresh monitor review for this

Points of interest:

- the advertised G2G response is never what you get for all transitions of color. Its a best-case scenario.
- advertised G2G may or may not include results from overdrive modes, but usually dó.
- not all overdrive modes are equal. This one does very little across its different settings, but the positive side is that there is also no overshoot (ghosting).

All things considered, ignore advertised G2G and check a review from https://www.tftcentral.co.uk

Another technology that is already mentioned up here is strobe, that can be used to reduce motion blur; also called BFI (Black Frame Insertion) or ULMB / ELMB. It introduces a black frame in between each screen refresh, which gives the image a more 'CRT' feel to it, at the cost of brightness. If you get a monitor that uses this, look for how bright it can be with it active and whether that suits your gaming area.

As for sensitivity to monitor qualities... its not only subjective, but it also changes over time; you get used to different monitors/display technologies and may notice the subtler details much later. The key point to avoid that is consistency; the overall G2G response number is less important than the outliers-the red boxes you see above here. Those are noticeable.

the advertised G2G response is never what you get for all transitions of color. Its a best-case scenario.

However, to meet several international regulations, including US regs, you have to be within 2% of stated specs and they do tests. Customs can be very rough.
