What's the reason for high refresh rates?

No Stupid QuestionsEnglish • 5 months ago

I was reading an article on the new LG display with a refresh rate of 7680Hz and it says:

While a typical refresh rate for a monitor might be 60Hz-240Hz, an outdoor display designed to be viewed from a distance needs to be much higher

The idea that there’s an intrinsic link between refresh rate and viewing distance is new to me and feels unintuitive. I can understand the need for high brighteness for far view distance. I also could understand refresh rate mattering for a non-persistent (CRT) display. But for an Led display surely you can see it far away even if it refreshes once a second?

Refresh rate normally needs to be high enough to avoid pixels “jumping” between refreshes on high resolution displays, so wouldn’t higher view distances allow you to decrease the refresh rate?

Is the article just spouting bullshit? Or is there an actual link between refresh rate and view distance?

Rules (interactive)

Rule 1- All posts must be legitimate questions. All post titles must include a question.

Rule 4- No self promotion or upvote-farming of any kind.

That’s it.

Rule 5- No baiting or sealioning or promoting an agenda.

Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it’s in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.

Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

Rule 8- All comments should try to stay relevant to their parent content.

Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.

Rule 10- Majority of bots aren't allowed to participate here.
